Fiber
Optic Impact and pressure Mat sensor (floor sensor)
Abacus Optical Mechanics fiber optic mat sensor consists of a flexible rubber /vinyl mat in which the sensor fiber is embedded. Any impact or vibration on or of the mat can be detected by the fiber sensor. When a certain threshold of impact is reached the optoelectronics box can trip a relay, which can reverse or stop a motor or sound a buzzer or trigger an electrical device. The sensitive of the device is adjustable down to impact of 1400 ergs. (Equivalent to a dime dropped from one inch.) |

Fiber
Optic Impact Edge Sensor
Abacus Optical Mechanics fiber optic "edge sensor" consists of a flexible rubber /vinyl extrusion in which the sensor fiber is embedded. Any impact, pressure, vibration on or of the edge sensor can be detected by the fiber sensor. When a certain threshold of impact is reached the optoelectronics box can trip a relay, which can reverse or stop a motor or sound a buzzer or trigger an electrical device. The sensitive of the device is adjustable down to impact of 1400 ergs. (Equivalent to a dime dropped from one inch.) |

Pressure/
Compression/ Impact (automotive window "anti squeeze sensor")
The fiber optic "anti-squeeze sensor" for car door windows consists of an optoelectronics box and a loop of fiber optic cable. The sensor fiber trunk is imbedded in the window seal and is sensitive to impact. When a certain threshold of impact is reached (due to body part e.g. finger) trapped in a closing window the electrical window motor is programmed to reverse |

(vehicle counter and weight in motion sensor) This device is used in automotive traffic control counting the number of vehicles passing a point as well as the weigh of each axle of the vehicle The sensing fiber trunk is embedded in a rubber extrusion that can be manufactured to any length. This extrusion is stretched across a street surface. Any impact on the extrusion caused by a vehicle passing over the extrusion results in a change in the optical signal. The greater the force of impact (which is proportional to speed and weight) the greater the resultant optical signal. Vehicle speed can be calculated timing the impact form the first sensor to the second sensor fiber. Knowing the impact force and the speed of the vehicle will enable the user to calculate the weight of each axle crossing the fiber sensor rubber hose. |
