The advent of listening and recording devices has significantly increased the number of cases involving illegal surveillance. This is cause for concern, primarily due to ethical considerations that often threaten an individual’s right to privacy. Bugs, also known as Covert Listening Devices, make it possible for anyone at any time to spy on you, with or without your knowledge or permission. Next time you stay at a hotel, motel or resort or become a new tenant in an apartment building, you might want to consider buying a bug detector to determine if you’re being watched. Here are some purchasing tips you should keep in mind:

Know the level of surveillance you may be facing
Most bugs you’ll probably encounter are low-level types, the kind used by amateur spies, voyeurs and landlords. If this is the case, a basic over-the-counter type of bug detector will work just fine. This type of detector will be able to sense bugs running on radio waves.

Look for a good range of detection
When purchasing a bug detector, check the range. This is usually expressed in MHz. A basic bug detector that can sense radio waves running from 1 MHz to about 3 MHz should work nicely for general needs.

Decide on the best warning feature that works for you
When purchasing a bug detector, ask what kind of warning feature it uses. Some bug detectors send out an audible alarm (usually beeps), while other units vibrate. Others have a small LED light that flashes to indicate the presence of a bug.

For general use, you might want to invest on a quiet bug detector. In case you go on a trip and decide to check a room, it will be discreet enough to use. That way, you can sweep a room, detect bugs and clear them without anyone else knowing it.

Too high-tech for you?
There are certain bugs that may not register on your bug detector. This usually happens if your detector can only sense radio waves. If a bug works on infra red, you could sweep a room completely and think it’s ‘clean’ when it’s not.

If you tried sweeping an area and nothing comes up and yet, there is still a bug present, it could be because the bug installed is the type used by government operatives or law enforcement officers. If this is the case, you might require the use of specialized bug detectors. These are usually made available to professionals such as detectives and law enforcement, which means you might have to hire someone to help you detect the bug and remove it. Your basic bug detector may not work in this case.

Bug detectors can be your best friend during this time of espionage and lack of respect for privacy. Find only the best bug detector for you.

With the advent of 3D printing technology the perimeters of design and engineering protocols have changed. Traditional protocols for engineering and design work required long periods of time between stages of development. 3D printer technology has dramatically shortened the time necessary between stages. Before the development of 3D printing technology prototyping required many man hours to produce a working prototype and the time necessary was multiplied each time a design change to the prototype had to be made. This added to the cost of product design and delayed products from moving to the next stage of development. 3D printing technology saves design teams a considerable amount to time and energy to produce prototypes and the application of design changes.

3D Printer Prototypes

With 3D printing technology come many advantages for the production of prototypes. From the conceptual to testing stage the technology has improve production speed, cost, and simplicity. A 3D printing system using rapid prototype technology enhances the design process by producing a 3 dimensional model. The 3D printing system produces an actual model that can be seen and manipulated by designers during various stages of the development process which helps engineers to facilitate prototype corrections and enhancements. Compared to a 3D printer, usual methods of producing prototypes is time consuming, costly and has to be repeated even if the smallest change is made to the design. Using a 3D printing system to enhance product designs is more efficient and cuts a great deal of time off the various stages of product development.

A 3D printer helps to reduce the bottom line cost of research and development by facilitating the prototyping process. Product development is a costly and prototype design and production can add considerable expense to a project. Multiple design changes, failure to meet deadlines and retooling only add to the bottom line expense of the production process. Utilizing a 3D printer will enhance the design process and cut costs where design changes have to be made by eliminating many of the costs associated with prototype production. With a 3D printing system no additional retooling or reengineering is necessary, because changes only have to be made in the computer assisted design software program. The whole process of creating, changing and constructing prototypes is enhanced through the use of 3D printing technology.

3D Printer Prototype Testing

3D printing technology assists in the prototype testing phase by producing prototypes in a more efficient and time sensitive manner. Where redesigning, retooling and recreating prototypes took a considerable amount of time, the 3D printing system can have a redesigned prototype ready for the next phase of testing in a much shorter period of time then conventional methods. Testing often requires product redesign and retesting, by having a swift technology like a 3D printer, testing can continue according to schedule without any undue delays and expense. It is not very often that a product is able to survive the testing phase of product development without some kind of design change. The 3D printer allows designers and engineers to utilize the advanced technology to their advantage and create better products.

Product testing is an important stage of new product development and a 3D printing system can enhance the testing phase and make the results more effective. Because a 3D printer reduces testing costs the process can be that much more effective. No one wants to be the one who tests a product after they have spent a substantial amount of money on it. As 3D printing technology continues to advance the product testing and development phase everyone will benefit from the technology. When a company can reduce research and development costs by using 3D printing technology, every one will benefit from the savings. The costs or savings for the testing, designing and producing of new products is always passed on to the purchaser of those products.

Polyjet Technology

Polyjet printing continues to utilize innovative and new approaches in 3D prototyping hardware, software and fabrication materials. Polyjet printing and a function of rapid prototyping technology is a design process using computer programming to guide the creation of a three dimensional model through the layering of fabrication material. The Polyjet heads deposit fabrication material in a building tray layer by layer and with concise precision until the prototype is built to complete specifications. Polyjet printers are able to use many different types of fabrication materials to build models and prototypes. Polyjet technology uses resins, polymers or photopolymers either singularly or in different combinations to build many different types of models.

Polyjet printing techniques utilize computer assisted design (CAD) which guides the building process step by step and ensures the correct construction of even the most complex of prototype designs. Polyjet printing heads are able to layer precise amounts of fabrication material during the layering process and build prototypes rapidly and accordingly to design specifications. During various stages of the Polyjet building process ultra-violet lights cure the fabrication materials which harden and produce a functional model or prototype. The Polyjet printing process is simple and easy including setup, printing and cleaning of the prototype model or product. Polyjet techniques for producing prototypes assist engineers in solving complex design issues early on in the development process.

Polyjet Advancements

Polyjet technology advancements are assisting designers to solve even the most complex design issues in the production of prototypes. A wide range of design flexibility is available to engineers with Polyjet printing techniques that were not previously available. Advancements in the computer assisted production of models now permits design changes to be implemented during any stage of the process. With the introduction of new polymer fabrication materials and the ability of Polyjet printers to utilize multiple materials in a single prototype project, designers can engineer many new features into their prototypes and models.

The introduction of advanced Polyjet technology allows the production of prototypes using thinner building lines, innovative fabrication materials and design accuracy. Polyjet printing technology continues to advance the ability to produce high quality and sophisticated prototypes. Polyjet printers are easy to program, set-up and rapidly produce prototypes. Instant and fully cured prototypes which need little post production work make Polyjet printing technology faster and very cost efficient for today’s competitive businesses and companies.

Increasingly video-based surveillance and security systems are being widely adopted by both corporations and consumers primarily due to increasing need for surveillance in these turbulent times but also due to affordability of security systems, ease with which surveillance systems can be installed and value-add features such remote monitoring that address special surveillance needs. As a result video-based surveillance systems are increasingly appearing in public areas such as airport lounges, shopping centres, retail stores, colleges, universities, manufacturing facilities and corporate offices. These video surveillance systems can be CCTV or IP based. Consider the benefits that a video surveillance system provides and the broad adoption by the market is quite understandable. A surveillance and security system:

• Helps deter employee theft and shoplifting theft,
• Helps monitor & document performance in manufacturing or other facilities resulting in potential reduction in maintenance cost and/or employee productivity improvement,
• May help reduce insurance cost and fraudulent liability claims, and
• Can continuously document events so your entire business has greater protection.

Reasons for Large LCD Monitor Adoption: Within these surveillance systems packages, large LCDs monitors (>42”) are becoming the industry norm. The reasons being:

• Size: Large screens allow for continuous and simultaneous monitoring of multiple camera video feeds on one screen with clarity. Smaller screens require that the images from the video feeds to rotate creating holes in the monitoring data.
• 24×7 Operations: Professional LCD monitors are meant for 24×7 “round the clock” operations with long life. CRT televisions or Plasma television each have their issues with round the clock operations such as static or flicker for CRT televisions. Also, the life of a CRT or Plasma TV is much shorter when operated in 24×7 operation mode as compared to an LCD monitor. CRT and Plasma televisions are built to be on for a few hours per day.
• Picture Quality: Most large LCDs are high definition. High definition LCDs provide better picture resolution, better contrast ratio, high brightness, high colour reproduction and fast response time resulting in better picture clarity which is especially helpful when the camera is being zoomed in or multiple images are viewed simultaneously. High Definition LCD TV allows you to view minute details like number plates of a speeding car, face of a person etc. Further, the non glare feature of LCDs allows for easy viewing in ambient light or where there is background light being reflected on the screen. It is harder to reduce glare in CRT or plasma televisions. Most new LCDs have 176° viewing angle, making it easy for viewing. Check the viewing specifications to make sure meets your quality requirements.
• Robustness: LCDs generate less heat than a CRT or Plasma television. The fan-less design for most large LCD monitors results in a closed box display with less noise. The fan-less design and the closed box display also results in less dust entering the system and provides for a more robust architecture.
• Space: LCD monitors are flat panel displays requiring less space than normal CRT TVs. They can be wall mounted. The LCD monitor can be encapsulated in a fire retardant frame to protect the display
• Better Video and Data Merger: Increasingly programs are being utilized to identify theft or issues in real time and data is being merged onto the video stream in real time. LCDs provide for better merging and viewing of data with video.
• Remote Monitoring and Operation of Large LCD Screens: Alarms can be set if an LCD screen is switched off. Power and other controls can be monitored remotely. For example, an energy saving feature can be activated so that when there is no signal, a power save mode is activated to reduce the brightness of the LCD backlight.
• Value-add Features: Value-add features such as touch screen zoom-in /zoom-out and image swap or other functions such as internet access can be easily found or added onto LCD monitors.

Purchase Consideration When Buying a Large LCD Monitor: Besides price there are a few items to consider when purchasing an LCD monitor.

• Match LCD Monitor to Camera Capabilities: If you buy a monitor with lower resolution than the cameras installed then the camera capabilities will not come through. Ideally the monitor should be equal or better resolution than the camera. Also, if the cameras are black and white, then a black and white monitor can be used.
• Input /Output Connectors on the Monitor: With the increasing use of PC and digital video devices, it is important to have both analog VGA and digital DVI input terminals to the monitor. Also, be sure that the monitor has BNC connectors for direct connection from a video feed to the display. BNC connectors support video looping, which provides output (loops back) to a centralized recording facility (DVR) or to other displays in a daisy-chain pattern. When scrolling through different images, this allows for seamless integration between pictures .
• Picture Quality Features: Consider the resolution, contrast ratio, brightness, colour reproduction and response time to meet your surveillance need.
• Value-add Features: Consider the value-adds that address your need. Such as, do you need remote monitoring, touch screen capability, or internet access?

Make the knowledgeable decision and your surveillance system can address your needs for many years.

Electronic book readers are in a funny place.

e-book readers are essentially cool gadgets – but the target market (avid readers) is a group likely to be more concerned with substance over style.

e-book readers work pretty well – but they’re new and still something of an unknown quantity. Most people still biding their time… so we still don’t know whether they’re the new iPod or the new Betamax.

e-book readers are money savers – and one of the great advantages is that you can get tons of reading material either free (out of copywrite literature) or for less than paper copies… and yet they cost about £200.

e-readers are also coming to maturity just at the time when people arew starting to spend less… so their fate be determined partly by completely unrelated economic factors…

So – should you take the plunge into e-books or not?

A few things to consider:

How much do you read?

 This is going to influence a) how much use you get out of the reader b) how much the convenience factor plays a part (if you only carry a single book once in a while, you won’t gain much from the portability of the reader) c) how much you will save on not buying hard-copy books.

In short, if you’re a light reader, e-book readers are probably not worth you’re while.

What do you read?

If you are into the classics and obscure books rather than bestsellers, getting a reader is going to mean that your reading material pretty much becomes free from now on! Popular books are cheaper on e-book than in hard-copy, but not by a lot.

Where do you read?

If you read at home (and particularly if you read in the

bath) then you’re probably better off with an old-fashioned book. If you travel a lot or commute, then the e-book reader really comes into its own.

Do you study?

e-book readers will probably become big news for students.

Being able to get all of your course books cheaper, lighter, and in one, portable place will make student’s lives a lot easier.

So are you an e-bookophile or a sceptic? If you’re interested in ebook readers, you can find out more and compare models at electronic book readers.

Happy reading, whatever you’re reading on!
