Preco Electronics Inc is a multinational vendor of radar-based object detection systems headquartered in Boise, Idaho, United States.
Preco was founded in 1947 by Edwin R. Peterson as a rebuilder of electronic water pumps, generators, and batteries [1] and introduced the first reverse-motion alarm in 1967.
PreView is a solid-state, pulsed-radar object detect system engineered to alert vehicle operators of both moving and stationary obstacles. [2] The system can also be combined with automatic braking systems to stop vehicles when an obstacle is near. [3] PreView is designed to work in extreme environmental conditions. [4]
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 and a receiver and processor to determine properties of the objects. Radio waves from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds.
Lidar is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. It can also be used to make digital 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has terrestrial, airborne, and mobile applications.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
Rome Laboratory is the US "Air Force 'superlab' for command, control, and communications" research and development and is responsible for planning and executing the USAF science and technology program.
Passive radar systems encompass a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of bistatic radar, the latter also including the exploitation of cooperative and non-cooperative radar transmitters.
Micropower impulse radar is a low-power ultra wideband radar developed in the mid-1990s at Lawrence Livermore National Laboratory, used for sensing and measuring distances to objects in proximity to each other.
The AN/MPQ-64 Sentinel is an X-band electronically steered pulse-Doppler 3D radar system used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. It is currently produced by Raytheon Missiles & Defense.
S. Scott Crump is the inventor of fused deposition modeling (FDM) and co-founder of Stratasys, Ltd. Crump invented and patented FDM technology in 1989 with his wife and Stratasys co-founder Lisa Crump. He is currently the chairman of the board of directors of Stratasys, which produces additive manufacturing machines for direct digital manufacturing ; these machines are popularly called “3D printers.” He took the manufacturing company public in 1994 (Nasdaq:SSYS). He also runs Fortus, RedEye on Demand, and Dimension Printing – business units of Stratasys.
The AN/SPS-67 is a short-range, two-dimensional, surface-search/navigation radar system that provides highly accurate surface and limited low-flyer detection and tracking capabilities.
North Truro Air Force Station (AFS) is a closed United States Air Force General Surveillance Radar station. It is located 2.2 mi (3.5 km) east of North Truro, Massachusetts.
A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system, or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar (all-weather) and sometimes laser (LIDAR) and cameras to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems.
BRP Andrés Bonifacio (PF-7) was a Philippine Navy frigate in commission from 1976 to 1985. She was one of six ex-United States Navy Barnegat-class small seaplane tenders/ex-United States Coast Guard Casco-class high endurance cutters received from the United States after the Vietnam War, two of which were acquired to supply spare parts for the other four. Andrés Bonifacio was considered the lead ship of her class in the Philippine Navy, and she and her three commissioned sister ships were the largest Philippine Navy combat ships of their time.
BRP Diego Silang (PF-9) was an Andrés Bonifacio-class frigate of the Philippine Navy in commission from 1976 to 1990. She and her three sister ships were the largest Philippine Navy ships of their time.
The BRP Francisco Dagohoy (PF-10) was an Andrés Bonifacio-class frigate of the Philippine Navy that served from 1979 to 1985. She was one of six ex-United States Navy Barnegat-class small seaplane tenders and ex-United States Coast Guard Casco-class high endurance cutters received from the United States after the Vietnam War, two of which were cannibalized for spare parts without entering service. She and her other three sister ships were the largest Philippine Navy ships of their time.
The BRP Gregorio del Pilar (PF-8) was an Andrés Bonifacio-class frigate of the Philippine Navy in commission from 1977 to 1990. She was one of six ex-United States Navy Barnegat-class seaplane tenders/ex-United States Coast Guard Casco-class high endurance cutters received from the United States after the Vietnam War, two of which were acquired to supply spare parts for the other four. She and her three commissioned sister ships were the largest Philippine Navy combat ships of their time.
The Elta 2052 is an X-Band airborne active electronically scanned array Fire Control Radar (FCR) designed for air-to-air superiority and strike missions based on fully solid-state Active Electronically Scanning Array (AESA) technology for fighter aircraft. It has been fitted for the SEPECAT Jaguar as part of Indian Air Force (IAF) DARIN III upgrade program. It has also been fitted for HAL Tejas, and described as suitable for use on the F-15, MiG-29, and Mirage 2000. The EL/M-2052 is an advanced Airborne Fire Control Radar (FCR) designed for air superiority and advanced strike missions.
Convergent encryption, also known as content hash keying, is a cryptosystem that produces identical ciphertext from identical plaintext files. This has applications in cloud computing to remove duplicate files from storage without the provider having access to the encryption keys. The combination of deduplication and convergent encryption was described in a backup system patent filed by Stac Electronics in 1995. This combination has been used by Farsite, Permabit, Freenet, MojoNation, GNUnet, flud, and the Tahoe Least-Authority File Store.
The TRML is a family of air defense radars first developed by Telefunken and currently produced by Hensoldt. It is a development of the earlier TRMS.
