Wireless Smoke Detector

Wireless Motion Detector: Uses and advantages

Wireless motion detector which speaks volumes of the technological advancement characterizing the modern century, is yet another device based on the principal of electromagnetism. As it makes use of electromagnetic waves to transmit signals or data, it does not involve the use of wires or cables.

 

Wireless motion detector which is used for security reasons, consists of a detector capable of detecting infrared rays and that of a transmitter module which is basically wireless. Both the detector and the infrared module are powered by batteries or electricity. The transmitter or the emitter emits infrared light or signals, while the detector receives the same. The modules which are positioned near a door or an opening to be monitored thus intercepts any obstructions between them, converting the same into light flash or a signal. Thus it intercepts the infrared rays converting them into light or sound energy.

 

Wireless motion detector is capable of ensuring complete domestic security. Any loopholes or any opening making possible way for an unwanted element or an intruder can be monitored by the means of a wireless motion detector. In keeping with the users convenience it can be switched on and off. There are different modes to which it can be attuned; depending on whether the person is awake or asleep at home or away from it. Some of the detectors are so attuned with a film that they do not register the movements of the object beneath a certain height. In this way possible movements of pets along the opening being monitored, do not unnecessarily send off panic alarms.

 

It is an automated way to ensuring home security. By giving out flashes of light and hooters, it is capable of frightening thieves or unwanted intruders. Moreover its small size makes for its convenience; as it can be used without appearing to be conspicuous. Besides these it is a wireless device and one need not worry about wires being messed up.

 

Certain kinds of advanced wireless motion detectors can also be used to indicate the infiltration of gas, smoke and floods. In this way a possible emergency can be avoided.

 

Various companies dealing with wireless security products have come up with devices which are also cost efficient and also a must for the purpose of home security. Apart from ensuring home security, it also has its use in industry. The detectors especially designed for the purpose, are useful for safeguarding industrial installations from unauthorized entry.

Why are they cutting NASA's budget so much?

They embody the people's dream of exploring space, and has done so much. The defense budget for last year was ~20% of federal spending, while NASA has accounted for >1% for the fast 35 YEARS.

Many advancements in science have been made by them, such as CAT scans, water purification tech, wireless gadgets, Smoke detectors, even those incredibly comfy memory foam pillows. They've made over 6000 patents, ad in return they get a budget cut.

They've inspired with these flights into space.
The Fisher pen wasn't designed for NASA, and both factions used pencils and they both switched to the pressurized pens because they don't want broken pencils and shaving floating around. Herp a derp

It's absolutely ridiculous. It's because they are spending all of our money on an unnecessary war. It's just sad.

The March of Technology (MIT)

Moore’s law and energy efficiency emerge as themes in these two lectures on
past and future progress in microprocessors and robotics.

Back in the old days, recalls **Rodney Brooks**, people were not allowed near
computers, because the smoke from human cigarettes might damage delicate
machinery. Then humans had to steer clear of robots, lest they come out on the
losing end of an encounter with a hulking machine limb. But following the
explosion of PC and portable computing technology, the last 10 years have
brought robots into close proximity with people. Brooks says more than nine
thousand robots now serve in the U.S. military, and six million work in human
homes -- including his own line at iRobot.

Brooks attributes this proliferation of AI aides to “IT exponentials that
beget other exponentials.” Leaps in processing speed enormously aided in the
development of essential robotics systems, such as vision, machine learning,
wireless networking, and speech understanding. He shows a robot, “The Cart,”
from Stanford’s AI lab circa 1979. The device relied on a giant mainframe
(shared with the music department), and moved 20 meters in six hours. By 2005,
Stanford’s AI vehicle Stanley was traveling 200 kilometers ...
