You remember those cheap spy gadget glasses or the disappearing ink that were in back of comic books but never delivered on their promise, but that was yesterday and today there are spy gadgets that are so high tech only you will know their secrets, not to mention most spy cameras are now in high definition and can record over 8 gigs of data all while still being wireless and affordable.

I know what your thinking and your right, spy gadgets are evil little electronics designed to trick us or catch us off guard, however this is quite the opposite. We have all been victims in the past and wondered if there was a way to catch who did us wrong whether it be stealing or vandalism, etc. Today’s technological advancements have paved the way for some secret covert spy gear. There are HD pinhole cameras, spy camera watches, video and audio sunglasses, spy pens, listening devices, and some real sneaky spy gadgets in places you never knew existed. Think of what your wearing right now as there is potential to replace any article of clothing or jewelry into a secret high tech spy gadget so you are always ready for any situation that may come up.

The cell phone technology has gone wild, but it’s very hard to look inconspicuous when trying to use these cameras and it is very obvious when you are trying to record video or snap a photo using it. Think of how many times you’ve been caught doing that already, the goal is to avoid blowing your cover. While being covert you can catch that neighbors dog eating your flowers, the lunch thief at work, record a conversation that has a potential “he said, she said” later on for your own protection, and use spy camera surveillance on any type of potential vandalism on your car, home or business, plus see who or what has been messing around in your backyard.

There are also many different kinds of nanny cams to keep a close eye on your loved ones and pets in addition to your property. Having trouble with a roommate or sibling and can’t prove it? Well, now you can with the right spy gadget in place and have the unmistakable proof to show police and law enforcement. You can even use your own bug detector to see if someone is spying on you! The police swat teams use all sorts of gadgets to catch the crooks and now you have access that type of spy gear as well.

Your probably wondering where can you buy spy equipment, the best spy gadgets can be found online in a matter of seconds. I live in a big city and have yet to find a good “spy store” in retail form.

High Technology Motion Sensors

Accelerometers

Accelerometers can be single or three axis devices; a typical single axis device is packaged in a 25 x 25 mm casing weighing 45 grams. This contains a pendulum (proof-mass) that senses acceleration. Relative displacement between the pendulum and casing is sensed by a high gain capacitance pick-off and a pair of coils.

A closed loop servomechanism feedback signal (proportional to acceleration) is then amplified and demodulated. This feedback signal (analogue current or digital pulses) is applied to the coils to restrain the pendulum at the null position.

The feedback required to maintain the null position is proportional to the sensed acceleration; this becomes the accelerometer’s output signal. Because of the high gain of the servomechanism electronics used, pendulum displacements are limited to microradians. An integral temperature sensor provides thermal compensation. The IRU contains three devices, measuring acceleration in the longitudinal, lateral and normal axes of the aircraft.

The primary sensors used in inertial navigation systems are accelerometers and gyros to determine the aircraft’s movement. These sensors provide outputs that are processed to provide basic navigation data.

The inertial navigation system needs to establish a local attitude reference and direction of true north for navigation purposes. During this process, the aircraft should not be moved.

MEMS based sensors

Developments in micro-electromechanical systems (MEMS) technology has led to silicon accelerometers that are more reliable and can be manufactured onto an integrated circuit. MEMS is the integration of mechanical elements, sensors and electronics on a common silicon substrate through micro-fabrication technology.
