Dashcam
A dashboard camera or simply dashcam, also known as car digital video recorder (car DVR), driving recorder, or event data recorder (EDR), is an onboard camera that continuously records the view through a vehicle's front windscreen and sometimes rear or other windows. Some dashcams include a camera to record the interior of the car in 360 degrees inside camera, usually in a ball form, and can automatically send pictures and video using 4G. EDRs and some dashcams also record acceleration/deceleration g-force, speed, steering angle, GPS data, voltage of the power source (vehicle's electrical net), etc. A wide-angle 130, 170° or more front camera may be attached to the interior windscreen, to the rear-view mirror (clip on), or to the top of the dashboard, by suction cup or adhesive-tape mount. A rear camera is usually mounted in the rear window or in the registration plate, with a RCA video output to the display monitor/screen. The resolution will determine the overall qual ...

Onboard Camera
An onboard camera or in-car camera is a camera placed upon a moving object, such as a vehicle. In motor racing, onboard cameras are often used to give a better perspective from the driver's point of view, whilst in films, these cameras are designed to increase the intensity and action of a specific scene. Onboard cameras were used in movies such as ''Le Mans'' and ''The Fast and the Furious'' series, for this purpose. Much of the original development work which led to the onboard cameras used today was performed by Australia's Seven Network, which introduced the technology at the 1979 Hardie-Ferodo 1000 endurance race at Mount Panorama. The original, Channel Seven, development team of John Porter and Peter Larsson moved to the states and formed Broadcast Sports Technology Inc.. BST then proceeded to recruit other staff from Channel Seven, notably Michael Katzmann. American audiences were first introduced to RaceCam at NASCAR's 1979 Daytona 500 on CBS network, and later at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear-view Mirror
A rear-view mirror (or rearview mirror) is a flat mirror in automobiles and other vehicles, designed to allow the driver to see rearward through the vehicle's rear window (rear windshield). In cars, the rear-view mirror is usually affixed to the top of the windshield on a double- swivel mount allowing it to be adjusted to suit the height and viewing angle of any driver and to swing harmlessly out of the way if impacted by a vehicle occupant in a collision. The rear-view mirror is augmented by one or more side-view mirrors, which serve as the only rear-vision mirrors on trucks, motorcycles and bicycles. History Among the rear-view mirror's early uses is a mention by Dorothy Levitt in her 1909 book ''The Woman and the Car'' which noted that women should "carry a little hand-mirror in a convenient place when driving" so they may "hold the mirror aloft from time to time in order to see behind while driving in traffic". However, earlier use is described in 1906, in a trad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trusted Timestamping
Trusted timestamping is the process of securely keeping track of the creation and modification time of a document. Security here means that no one—not even the owner of the document—should be able to change it once it has been recorded provided that the timestamper's integrity is never compromised. The administrative aspect involves setting up a publicly available, trusted timestamp management infrastructure to collect, process and renew timestamps. History The idea of timestamping information is centuries old. For example, when Robert Hooke discovered Hooke's law in 1660, he did not want to publish it yet, but wanted to be able to claim priority. So he published the anagram ''ceiiinosssttuv'' and later published the translation ''ut tensio sic vis'' (Latin for "as is the extension, so is the force"). Similarly, Galileo first published his discovery of the phases of Venus in the anagram form. Sir Isaac Newton, in responding to questions from Leibniz in a letter in 167 ...

Dashboard
For business applications, see Dashboard (business). A dashboard (also called dash, instrument panel (IP), or fascia) is a control panel set within the central console of a vehicle or small aircraft. Usually located directly ahead of the driver (or pilot), it displays instrumentation and controls for the vehicle's operation. Etymology Originally, the word ''dashboard'' applied to a barrier of wood or leather fixed at the front of a horse-drawn carriage or sleigh to protect the driver from mud or other debris "dashed up" (thrown up) by the horses' hooves. The first known use of the term (hyphenated as ''dash-board'', and applied to sleighs) dates from 1847. Commonly these boards did not perform any additional function other than providing a convenient handhold for ascending into the driver's seat, or a small clip with which to secure the reins when not in use. When the first "horseless carriages" were constructed in the late 19th century, with engines mounted beneath the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Event Data Recorder
An event data recorder (EDR), more specifically motor vehicle event data recorder (MVEDR), similar to an accident data recorder (ADR) sometimes referred to informally as an automotive black box (by analogy with the common nickname for flight recorders), is a device installed in some automobiles to record information related to traffic collisions. In the USA EDRs must meet federal standards, as described within the U.S. Code of Federal Regulations. The term generally refers to a simple, tamper-proof, read-write memory device. The role of the EDR is limited compared to journey data recorders such as digital tachograph in Europe or electronic logging device in the USA which may also be referred to as a black box or in-vehicle data recorder. In modern diesel trucks, EDRs are triggered by electronically sensed problems in the engine (often called faults), or a sudden change in wheel speed. One or more of these conditions may occur because of an accident. Information from these de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wide-angle Lens
In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it. Another use is where the photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away. This exaggeration of relative size can be used to make foreground objects more prominent and striking, while capturing expansive backgrounds. A wide angle lens is also one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length. This large image circle enables either ...

Touch Screen
A touchscreen or touch screen is the assembly of both an input ('touch panel') and output ('display') device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is optio ...

Advanced Driver-assistance Systems
An advanced driver-assistance system (ADAS) is any of a groups of electronic technologies that assist drivers in driving and parking functions. Through a safe human-machine interface, ADAS increase car and road safety. ADAS uses 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, depending on the features installed in the car. As most road crashes occur due to human error, ADAS are developed to automate, adapt, and enhance vehicle technology for safety and better driving. ADAS are proven to reduce road fatalities by minimizing human error. Safety features are designed to avoid crashes and collisions by offering technologies that alert the driver to problems, implementing safeguards, and taking control of the vehicle if necessary. Adaptive features may automate lighting, provide adaptive cruise control, assist in avoiding collisions, incorporate satellite navig ...

Motion Detector
A motion detector is an electrical device that utilizes a sensor to detect nearby motion. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. They form a vital component of security, automated lighting control, home control, energy efficiency, and other useful systems. Overview An ''active'' electronic motion detector contains an optical, microwave, or acoustic sensor, as well as a transmitter. However, a ''passive'' contains only a sensor and only senses a signature from the moving object via emission or reflection. Changes in the optical, microwave or acoustic field in the device's proximity are interpreted by the electronics based on one of several technologies. Most low-cost motion detectors can detect motion at distances of about . Specialized systems are more expensive but have either increased sensitivity or much longer ranges. Tomographic motion detection systems can cover much larger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
