摘要： Monitoring system for use in detecting the presence of an obstacle in or proximate to an aperture (20). Materials are applied to one or more reflecting surfaces adjacent the aperture, enabling the improvement of the signal-to-noise ratio in the system without requiring tuning the system for the particular environment. The choice of specific material depends upon the type of radiation used for aperture monitoring and whether an obstacle is detected as an increase or decrease in reflected radiation. A calibration LED within the monitoring system enables predictable performance over a range of temperatures. The monitoring system is also provided with the capacity to adjust to variations in the background-reflected radiation, either automatically by monitoring trends in system performance or by external command. The latter case includes the use of a further element for communicating to the monitoring system directly or indirectly.

摘要： An object detection system (100) employs a photo-emitter (102) and photo-detector (104) for synchronously detecting and processing an optical signal (105) reflected from an object in a pinch zone of a window or door opening (101). A photo-emitter light signal (103) is modulated by a modulation signal (109) having an active phase and an inactive phase. The optical detector (104) provides an optical detector signal (107) that is a function of the intensity of the received light (105). The detected light (107) signal is synchronously detected using a switching amplifier (108) that multiplies the reflected modulated light signal by a first gain during the active phase and by a second gain during the inactive phase. The duration of the active and inactive phases and the first and second gains are selected such that the system gain will average to zero for ambient light when integrated over a predetermined measurement period. The synchronously detected signal is substracted (118) from a predetermined offset voltage, and this difference is then integrated over the measurement period. The output of the integrator (114) in then compared to a predetermined threshold value.

摘要： A hybrid obstacle detection system for a power driven closure (12) including a non-contact obstacle detection system (14) and a contact-based obstacle detection system (100). The hybrid system combines the beneficial aspects of contact and non-contact systems while avoiding the deficiencies characteristic of the constituent systems when employed alone. In the non-contact system, the closure itself may interfere with and degrade performance. In the contact-based system, physical contact with an obstacle is required before the obstacle can be detected and corrective action can be taken. Inputs from both the contact-based system and the non-contact system may be utilized over the entire closure travel path, or may be invoked only within a specific portion of the closure travel path. Either or both of the constituent systems may be used to ascertain the location of the closure. A central controller (202) may be used for coordinating the inputs from the two systems, or a controller associated with one of these systems may be adapted for this purpose. If the central controller is employed, it may be a controller dedicated to this function, or one which is already utilized in the environment of the aperture for another purpose.

摘要： In an infrared obstruction detection system, an apparatus is used to detect the presence of ambient light and initiate compensation to minimize the effects of the ambient light on the performance of the system. In one embodiment, the magnitude of the ambient light is measured and an offset proportional to that magnitude is fed to the obstruction detection system such that the data indicative of an obstacle are not obscured. In another embodiment, the apparatus continually monitors the effect of ambient light and adjusts the obstacle detection information during the changing states of the ambient light detected.

摘要： An obstacle detection system for vehicular environments including a monitoring sensor system and a mounting system enables an installer to make aiming adjustments, in the factory or field, to account for tolerance stack-up. The system includes a housing for mounting the monitoring sensor system to minimize cross-talk and interference between transmitter and receiver sections, to limit sensor system movement, and to enable gross and fine amining adjustments. In one embodiment, a circuit board (120) is disposed within a cradle assembly (62) which, in turn, is mounted in (110) or integral to the housing (60) to position the sensor as necessary. The cradle in one embodiment is an enclosure for the circuit board. The sensor housing is mounted to the interior vehicle trim, door panel, and/or door sheet metal and ensures consistent mounting regardless of interior trim or factory installation variations. Integral adjustment mechanisms are incorporated for adjusting the orientation of the sensor system.
