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 system that uses radio waves to determine the distance (ranging), direction, and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
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. Lidar may operate in a fixed direction or it may scan multiple directions, in which case it is known as lidar scanning or 3D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array 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).
Advanced driver-assistance systems (ADAS) are technologies that assist drivers with the safe operation of a vehicle. Through a human-machine interface, ADAS increase car and road safety. ADAS use automated technology, such as sensors and cameras, to detect nearby obstacles or driver errors, and respond accordingly. ADAS can enable various levels of autonomous driving.
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.
The Type 81 Surface-to-Air Missile (81式短距離地対空誘導弾) or Tan-SAM (短SAM) is a Japanese developed surface-to-air missile currently in service with the Japan Ground Self-Defense Force.
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.
Adaptive cruise control (ACC) is a type of advanced driver-assistance system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. As of 2019, it is also called by 20 unique names that describe that basic functionality. This is also known as Dynamic cruise control.
A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system (FCW), 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.
Pocket Radar products are handheld K‐band Doppler speed radar guns developed and manufactured by Pocket Radar, Inc, a company based in Santa Rosa, California. It was intended for those wishing to measure the speed of everyday objects.
LEDDAR is a proprietary technology owned by LeddarTech. It uses the time of flight of light signals and signal processing algorithms to detect, locate, and measure objects in its field of view.
Human sensing encompasses a range of technologies for detecting the presence of a human body in an area of space, typically without the intentional participation of the detected person. Common applications include search and rescue, surveillance, and customer analytics.
Pedestrian crash avoidance mitigation (PCAM) systems, also known as pedestrian protection or detection systems, use computer and artificial intelligence technology to recognize pedestrians and bicycles in an automobile's path to take action for safety. PCAM systems are often part of a pre-collision system available in several high end car manufacturers, such as Volvo and Mercedes and Lexus, and used less widely in lower end cars such as Ford and Nissan. As of 2018 using 2016 data, more than 6,000 pedestrians and 800 cyclists are killed every year in the US in car crashes. Effective systems deployed widely could save up to 50% of these lives. More than 270,000 pedestrians are killed every year in the world. An excellent analysis of technology capabilities and limitations is provided in Death of Elaine Herzberg. Pedestrian safety has traditionally taken a secondary role to passenger safety.
RF CMOS is a metal–oxide–semiconductor (MOS) integrated circuit (IC) technology that integrates radio-frequency (RF), analog and digital electronics on a mixed-signal CMOS RF circuit chip. It is widely used in modern wireless telecommunications, such as cellular networks, Bluetooth, Wi-Fi, GPS receivers, broadcasting, vehicular communication systems, and the radio transceivers in all modern mobile phones and wireless networking devices. RF CMOS technology was pioneered by Pakistani engineer Asad Ali Abidi at UCLA during the late 1980s to early 1990s, and helped bring about the wireless revolution with the introduction of digital signal processing in wireless communications. The development and design of RF CMOS devices was enabled by van der Ziel's FET RF noise model, which was published in the early 1960s and remained largely forgotten until the 1990s.
