Pocket Radar
Pocket Radar products are handheld K‐band Doppler speed radar guns developed and manufactured by Santa Rosa, Calif.‐based Pocket Radar, Inc. It was intended for those wishing to measure the speed of everyday objects (such as cars and people). Functionality Pocket Radar utilizes very similar microwave signal emission and detection methods found in the Doppler speed radar guns used by law enforcement agencies. The device measures and weighs . when equipped with two AAA batteries. It operates at the 24.125 GHz K-Band frequency and can measure speeds ranging from {{convert, 7, to, 375, mph, abbr=on with an accuracy of ±1 mph (±1.6 km/h) and can also measure feet/second and meters/second. Pocket Radar, Inc Pocket Radar was developed and manufactured by Pocket Radar, Inc. of Santa Rosa, California. The company’s founders, Chris Stewart, Steve Goody, and Grant Moulton were developers in wireless and communication technology companies Hewlett Packard, Cerent Cor ...

K Band (IEEE)
The IEEE K-band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27-Gigahertz (GHz). The range of frequencies in the center of the K-band between 18- and 26.5-GHz is absorbed by water vapor in the atmosphere due to its resonance peak at 22.24-GHz, . Therefore these frequencies experience high atmospheric attenuation and cannot be used for long distance applications. For this reason the original K-band has been split into three bands, Ka-band, K-band, and Ku-band as detailed below. The K stands for Kurz which stems from the German word for short. Subdivisions Because of the water vapor absorption peak in the center of the band, the IEEE K-band is conventionally divided into three sub-bands: * Ku-band: K-under band, 12–18-GHz, mainly used for satellite communications, direct-broadcast satellite television, terrestrial microwave communications, and radar, especially police traffic-speed detectors. * K-band 18–27-GHz: Due to the 22-GHz wate ...

Doppler Radar
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Concept Doppler effect The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference between the observed frequency and the emitted frequency of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession. This variation of f ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

AAA Batteries
The AAA battery (or triple-A battery) is a standard size of dry cell battery. One or more AAA batteries are commonly used in low-drain portable electronic devices. A zinc–carbon battery in this size is designated by IEC as R03, by ANSI C18.1 as 24, by old JIS standard as UM-4, and by other manufacturer and national standard designations that vary depending on the cell chemistry. The size was first introduced by The American Ever Ready Company in 1911. An AAA battery is a single cell that measures in diameter and in length, including the positive terminal button, which is a minimum . The positive terminal has a maximum diameter of ; the flat negative terminal has a minimum diameter of . Alkaline AAA batteries weigh around , while primary lithium AAA batteries weigh about . Rechargeable nickel–metal hydride (NiMH) AAA batteries typically weigh . Use AAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital camer ...

Hewlett Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally esta ...

Cerent Corporation
Cerent Corporation was an optical equipment maker based in Petaluma, California. It was founded in 1997 as Fiberlane Communications with funding from Kleiner Perkins Caufield & Byers and Vinod Khosla as the managing VC. The company was founded with three divisions: Systems in Petaluma, Chip Design in Mountain View, California and Network Management Systems in Burnaby, British Columbia. In early 1998 the company split into two companies with the Petaluma branch becoming Cerent and the Burnaby and Mountain View branches becoming Siara Systems (Acquired by Redback Networks in 1999). The Cerent 454 Cerent's first product was the Cerent 454 (later the Cisco 15454). The Cerent 454 was a second generation SONET ADM (Add-Drop Multiplexor) that also supported TCP/IP data switching. When operating as a pure ADM, the 454 could add and drop circuits from OC-192 down to Digital Signal 1 (DS1) -- later it would support Wavelength Division Multiplexing (WDM). Unlike the ADMs that preceded it, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
