Abstract: An object detection system includes an emitter, a receiver, and a controller adjacent a window assembly which typically includes a moveable glass member and a frame. In operation the emitter transmits the electromagnetic through a defined field adjacent a closure path of a moveable glass member. The controller constructs a map of the signal received by the receiver such that insertion of an object within the defined field produces a variation in the map. The controller halts or reverses the movement of the moveable glass member to prevent trapping the object between the closing moveable glass member and the frame.

Abstract: A power window apparatus that inhibits leakage current when submerged in water. The power window apparatus includes an operation switch. A microcomputer controls a motor. A connector has a down terminal and an up terminal connecting the operation switch and the microcomputer, and a ground terminal used to connect the operation switch and the ground. When operated, the operation switch connects the down terminal or the up terminal to the ground terminal and generates a low-level input signal in the down terminal or in the up terminal. The microcomputer drives the motor in response to the low-level input signal. An inhibition mechanism arranged in the connector inhibits, when water enters into the connector, a leakage current from flowing between a connecting terminal and a ground terminal.

Abstract: A detector, that prevents erroneous detection of a foreign object caught in a window glass when the engine of a vehicle is being operated and when the engine is stopped using a relatively simple control method. The detector includes a pulse sensor for detecting rotational speed of a motor. A microcomputer calculates a cycle difference sum based on the rotational speed of the motor. The microcomputer compares the cycle difference sum with a obstruction determination threshold to determine whether a foreign object has been caught. The microcomputer detects whether the engine is stopped. When detecting that the engine is stopped, the microcomputer changes the obstruction determination threshold so that the probability of the microcomputer determining that a foreign object has been caught is lower than that when the engine is being operated.

Abstract: An antipinch circuit prevents the motor driven closure of an automotive window if a soft obstacle is compressed between the window and the top of the door frame, and the window is opened in response to the sensing of the obstacle. The circuit measures the motor torque (by measuring motor current) and the motor shaft speed (by measuring motor back EMF). The torque and motor speed are compared to “signatures” of these values in the case of the window closing normally against the top of the door frame, or against an obstacle, and either stopping or reversing the motor rotation accordingly.

Abstract: An improved system for detecting the presence of an object in the path of a liftgate relies upon the sensor/transmitters that are used for collision avoidance systems to detect the presence of an object rearwardly of a vehicle moving in a reverse direction. Known sensors are provided to look for the presence of an object when the vehicle is being moved in a reverse direction. The sensors are now also actuated when the liftgate is being moved to its closed position. Should an object be detected, further movement of the liftgate is stopped. The present invention thus detects the presence of an object in the path of a liftgate prior to any contact. Further, the invention combines two prior control modules into a single control module.

Abstract: A control apparatus and method for a panel movable between at least two positions by an electric motor having a rotatable armature. The control generates time periods for the rotation of the armature over a constant angular distance. An average time period is computed over a predetermined number of time periods and compared with a threshold time period to determine if an obstacle is present in the path of movement of the closure. Transient counts are accumulated for increasing average time periods over a number of time period samples to detect an obstacle. A compensation factor is used to adjust a threshold upon detecting a start-up transient during an initial movement of the motor armature coupled to the panel to delay activation of obstacle detection until the start-up transient diminishes.

Abstract: An impact sensing system for a powered roll-up door combines an electrical switch and a breakaway coupling. To avoid damage or injury resulting from the door's roll-up curtain accidentally closing upon an obstacle or something striking the curtain, the breakaway coupling responds to such a collision by breaking away, which releases a lower portion of the curtain from between its two vertical guide tracks. Each breakaway coupling includes a set of electrical contacts that make or break in response to the coupling breaking away. When the curtain's lower portion becomes effectively derailed from its guide track, the electrical contacts disable continued operation of the door to prevent the door's drive motor from jamming the curtain. In some embodiments, the breakaway coupling is releasably held together by way of magnetic attraction between two coupling segments, with one electrical contact on each segment to comprise one set of functional contacts.

Abstract: A force-responsive sensor comprises upper and lower cover layers, the upper layer being resilient and flexible and shown as transparent for ease of illustration. An electrically conductive layer carries separate individual electrically insulating spacers which separate it from two electrically conductive members. Each of these members has a plurality of spaced resilient fingers, the fingers of the two members being inter-digitated. The members are formed as films on the layer. Where the members are not supported by the spacers, they are normally held apart from the conductive layer by the resilience of the upper layer. In response to an applied force, one or more of the fingers is pressed into contact with the conductive layer to enable the production of a corresponding electrical signal. The positioning of the spacers ensures that they do not increase the overall width of the sensor. A force applied by a relatively large-area flat object is transmitted by a protruberance to one of the fingers.
