摘要： A system, method and mirror are provided in order to more reliably detect the presence of an object, such as a person. In the context of a system, the system includes a sensor configured to emit signals having a predefined wavelength and to detect a reflection of the signals having the predefined wavelength. The system also includes a reflective surface positioned relative to the sensor such that the signals emitted by the sensor are directed toward the reflected surface. The system further includes a filter associated with the reflective surface and positioned relative to the sensor such that the signals emitted by the sensor are also directed toward the filter. The filter is configured to attenuate at least signals having the predefined wavelength.

摘要： A system includes a computer including a processor and a memory. The memory stores instructions executable by the processor to receive a reflection magnitude from an infrared sensor during a movement of an object relative to the infrared sensor, to determine a change of the reflection magnitude, and to detect the object based on comparing the determined change of the received reflection magnitude to a change threshold.

摘要： A system to detect obstacles includes a power beam transmission circuit, a power beam reception circuit arranged to receive a power beam from the power beam transmission circuit, an emitter module, and a detector module arranged to distinguish between a first characteristic and a second characteristic. The emitter module includes a first emitter arranged to emit a first signal having the first characteristic, the first signal emitted in proximity to the power beam, and a second emitter arranged to emit a second signal having the second characteristic, the second characteristic different from the first characteristic, the second signal emitted in proximity to the first signal. The detector module includes a first detector arranged to respond to the first signal emitted by the first emitter, wherein the detector module is arranged to determine when an obstacle is in or near a line-of-sight transmission path between the first emitter and the first detector.

摘要： An information handling system manages operation of an infrared time of flight sensor to provide accurate and timely user presence and absence detection through modulation in the frequency domain of infrared light, such as by hopping or multiplexing through plural infrared frequencies sensed by the time of flight sensor. An application of the information handling system retrieves calibration information from the infrared time of flight sensor and applies the calibration information to select the plural infrared frequencies. If one or more predetermined conditions, such as a change in ambient light characteristics, the application commands an update of the calibration information to enhance user presence and absence detection.
