The dihedral synchro-helix actuation door system is a type of door with a hinge mechanism which allows the doors to rotate 90° by sweeping outwards and upwards at the hinge. [1] It was designed and developed by Christian von Koenigsegg on behalf of high-performance sports cars manufacturer, Koenigsegg Automotive AB . [ 2 ]
High-speed doors are door systems, mainly used in industrial applications. They are technical enhancements of the generally known sectional doors, PVC fabric doors or roller shutters . The main difference is that the durable construction provides a higher operating speed and they are able to sustain a higher number of cycles (opening and ...
In high-security buildings, access control systems are sometimes set up so that ability to open one door requires another one to be closed first. Such setups are called a mantrap. Interlocks can be used as a high level entrance security. There are two kinds of interlocking systems for security.
Entrance to HM Prison Edinburgh. A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens.
The automatic door used a mat actuator. In 1960, they co-founded Horton Automatics Inc and placed the first commercial automatic sliding door on the market. [5] With the invention of the Gunn diode, microwave motion detectors became common in automatic doors in the 1970s. [6] [7] In 1980, the first automatic door using an infrared sensor was ...
A given VR-sensing system has a definite limit as to how slow the target can move and still develop a usable signal. An alternative but more expensive technology is Hall effect sensor . Hall effect sensors are true zero-rpm sensors and actively supply information even when there's no transmission motion at all.
If the signal lies close to the constant current supply voltage, there is no sensor present or the cable path has been interrupted. A signal close to the saturation voltage, indicates a short circuit in the sensor or cable. In between these two limits a functional sensor has been detected.
NonStop is a series of server computers introduced to market in 1976 by Tandem Computers Inc., [1] beginning with the NonStop product line. [2] It was followed by the Tandem Integrity NonStop line of lock-step fault-tolerant computers, now defunct (not to be confused with the later and much different Hewlett-Packard Integrity product line extension).
