Anti-hijack System
An anti-hijack system is an electronic system fitted to motor vehicles to deter criminals from hijacking them. Although these types of systems are becoming more common on newer cars, they have not caused a decrease in insurance premiums as they are not as widely known as other more common anti-theft systems such as alarms or steering locks. It can also be a part of an alarm or immobiliser system. An approved anti-hijacking system will achieve a safe, quick shutdown of the vehicle it is attached to. There are also mechanical anti-hijack devices. Diversify Solutions, a company in South Africa, has announced its research and development at the Nelson Mandela University of a GSM based Anti hijacking system. The system works off a verification process with added features such as alcohol sensors and signal jamming capabilities, this comes after increasing rates of hijackings in South Africa and alarming rates of accidents caused by driving under the influence and texting whilst d ...

Access Control
In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of ''accessing'' may mean consuming, entering, or using. Permission to access a resource is called ''authorization''. Locks and login credentials are two analogous mechanisms of access control. Physical security Geographical access control may be enforced by personnel (e.g. border guard, bouncer, ticket checker), or with a device such as a turnstile. There may be fences to avoid circumventing this access control. An alternative of access control in the strict sense (physically controlling access itself) is a system of checking authorized presence, see e.g. Ticket controller (transportation). A variant is exit control, e.g. of a shop (checkout) or a country. The term access control refers to the practice of restricting entrance to a property, a building, or a room ...

Embedded Systems
An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is ''embedded'' as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems. In either case, the processor(s) us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crime Prevention
Crime prevention is the attempt to reduce and deter crime and criminals. It is applied specifically to efforts made by governments to reduce crime, enforce the law, and maintain criminal justice. Studies Criminologists, commissions, and research bodies such as the World Health Organization, United Nations, the United States National Research Council, the UK Audit Commission have analyzed their and others' research on what lowers rates of interpersonal crime. They agree that governments must go beyond law enforcement and criminal justice to tackle the risk factors that cause crime, because it is more cost effective and leads to greater social benefits than the standard ways of responding to crime. Multiple opinion polls also confirm public support for investment in prevention. Waller uses these materials in '' Less Law, More Order'' to propose specific measures to reduce crime as well as a crime bill. The ''World Health Organization Guide'' (2004) complements the ''World Repor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automotive Accessories
The automotive aftermarket is the secondary market of the automotive industry, concerned with the manufacturing, remanufacturing, distribution, retailing, and installation of all vehicle parts, chemicals, equipment, and accessories, ''after'' the sale of the automobile by the original equipment manufacturer (OEM) to the consumer. The parts, accessories, etc. for sale may or may not be manufactured by the OEM. According to a report by the International Trade Administration in the US Department of Commerce, "''Aftermarket parts are divided into two categories: replacement parts and accessories. Replacement parts are automotive parts built or remanufactured to replace OE parts as they become worn or damaged. Accessories are parts made for comfort, convenience, performance, safety, or customization, and are designed for add-on after the original sale of the motor vehicle.''" The aftermarket encompasses parts for replacement, collision, appearance, and performance. The aftermarket provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blaster (flamethrower)
The Blaster (also called the "BMW Flamethrower") was a 1998 invention by South African inventor Charl Fourie as an car-mounted laterally-firing flamethrower, designed to provide a defence against carjackings. The Blaster was a liquefied petroleum gas flamethrower installed along the sides of the vehicle under the doors. Should a group of carjackers suddenly attack the vehicle while it is stopped in traffic (the typical scenario), the occupant could flip a switch and direct plumes of flame upward into the facial area of anyone trying to enter the vehicle through the doors or windows. Fourie claimed it was unlikely to kill but would "definitely blind" the assailant. In South Africa, it is legal to use lethal force in self-defence if in fear of one's life, and ownership of flamethrowers is unrestricted. The invention came in response to the increasingly severe violent crime situation in South Africa, which in 1998 had already made the country (particularly Johannesburg) the per ...

Vehicle Tracking System
A vehicle tracking system combines the use of automatic vehicle location in individual vehicles with software that collects these fleet data for a comprehensive picture of vehicle locations. Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software. Urban public transit authorities are an increasingly common user of vehicle tracking systems, particularly in large cities. Active versus passive tracking Several types of vehicle tracking devices exist. Typically they are classified as "passive" and "active". "Passive" devices store GPS location, speed, heading and sometimes a trigger event such as key on/off, door open/closed. Once the vehicle returns to a predetermined point, the device is removed and the data downloaded to a computer for evaluation. Passive systems include ...

Car Alarm
A car alarm is an electronic device installed in a vehicle in an attempt to discourage theft of the vehicle itself, its contents, or both. Car alarms work by emitting high-volume sound (often a vehicle-mounted siren, klaxon, pre-recorded verbal warning, the vehicle's own horn, or a combination of these) when the conditions necessary for triggering it are met. Such alarms may also cause the vehicle's headlights to flash, may notify the car's owner of the incident via a paging system, and may interrupt one or more electrical circuits necessary for the car to start. Although inexpensive to acquire and install, the effectiveness of such devices in deterring vehicle burglary or theft when their only effect is to emit sound appears to be negligible. History An early version of a car alarm for use as a theft deterrent was invented by an unknown prisoner from Denver in 1913. This version was manually armed, and triggered when someone tried to crank the engine. A later alarm inspired b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immobiliser
An immobiliser or immobilizer is an electronic security device fitted to a motor vehicle that prevents the engine from being started unless the correct key (''transponder'' or ''smart key'') is present. This prevents the vehicle from being "Hotwiring, hot wired" after entry has been achieved and thus reduces motor vehicle theft. Research shows that the uniform application of immobilisers reduced the rate of car theft by 40%. Description The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbuel and patented in 1919. They developed a 3x3 grid of double-contact Electric switchboard, switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and Car alarm, sounding the Vehicle horn, horn. The system settings could be changed each time the car was driven. Modern immobiliser systems are automatic, mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hazard Lights
The lighting system of a motor vehicle consists of lighting and signalling devices mounted to or integrated into the front, rear, sides, and in some cases the top of a motor vehicle. They illuminate the road ahead for the driver and increase the vehicle's visibility, allowing other drivers and pedestrians to see its presence, position, size, direction of travel, and its driver's intentions. Emergency vehicles usually have distinctive lighting equipment to warn drivers and indicate priority of movement in traffic. History Early road vehicles used fuelled lamps before the availability of electric lighting. The Ford Model T used carbide lamps for headlights and oil lamps for tail lights. It did not have all-electric lighting as a standard feature until several years after its introduction. Dynamos for automobile headlights were first fitted around 1908 and became commonplace in 1920s automobiles. Silent film star Florence Lawrence is often credited with designing the first " ...

Microswitch
A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism. Switching happens reliably at specific and repeatable positions of the actuator, which is not necessarily true of other mechanisms. They are very common due to their low cost but high durability, greater than 1 million cycles, and up to 10 million cycles for heavy-duty models. This durability is a natural consequence of the design. The defining feature of micro switches is that a relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation). Most successful designs also exhibit hysteresis, meaning that a small reversal of the actuator is insufficient to reverse the contacts; there must be a significant movement in th ...
