    Abstract: A firearm training system includes a training firearm (40) which includes a laser transmitter module (22) that emits a laser signal along a longitudinal centerline of the barrel (10) of the firearm in response to a mechanical wave generated from pulling the trigger of the firearm. A laser-detecting target (42) includes a planar array of laser light detectors capable of detecting the exact location that the laser signal hits the target. The laser signal transmitted by the training firearm (40) is preferably a modulated laser pulse that the target (42) can easily discriminate from noise and interference. The target is connected to a computer (44) which reports laser hit information and keeps track of a sequence of laser hits fired by a competitor or trainee. Computer (44) can be linked via a communications network to similar firearm training systems to enable competition between shooters at different geographic locations.

    Abstract: An apparatus and method for sensor-based interface with feedback are provided for user input to programmable electrical systems, the sensor having a long life and high reliability and being activated by a user action, where the sensor is, for example, a photoelectric sensor, magnetic sensor, Hall effect based sensor, sensor based on capacitance change, proximity sensor, and a resistance sensor. Inputs are made in a predetermined sequence of preset nulltime windowsnull by having a user, while in close proximity to the sensor, provide power to the electrical system to initiate a programming sequence and then activate the sensor one or more times in order to set the preprogrammed sequence of variable control values. Feedback of each activation as it is sensed by the sensor is provided immediately to the user, for example by a light emitting diode (LED) and default values result from lack of input.

    Abstract: Detection of interfering light is performed based on an interfering light detection timing signal Si set immediately before a blockage detection timing signal Sr. If interfering light is detected consecutively with respect to the same optical axis according to interfering light detection timing, the length of blank period tb is reduced to shift the positions of pulses of the blockage detection timing signal, thereby avoiding overlap between these pulses and pulses of interfering light on the time axis. In this manner, mutual interference between multiple-axis photoelectric sensors can be prevented without providing sync line wiring between the photoelectric sensors.

    Abstract: An integrated circuit package including an optical sensor array is provided with a transparent window comprising a thermoset plastic, such as an epoxy transfer clear molding compound, that is resistant to the elevated temperatures found in semiconductor processing and is configured as a lens, to improve the image quality of the image incident on the sensor. As an example, a field flattener lens is incorporated into the window to form an integral element that also acts as an hermetic seal. Thus, the field flattener is made integral with the sensor. The thermoset lens provides two functions: (1) it improves the image quality; and (2) it protects the sensor from damage and contamination. This protection is normally provided by a glass window on the sensor, but is no longer necessary by virtue of the present invention.

    Abstract: An approach is provided for detecting EM waves using a photodetector coupled to an amplifier stage. The amplifier stage uses capacitive feedback to reduce or cancel intrinsic capacitance of the photodetector. A variety of capacitance structures may be used to provide the capacitive feedback such as shielded capacitors and capacitor arrays. The amplifier stage may be either single-ended or fully differential, depending upon the requirements of a particular application. Noise cancellation circuitry may also be included to reduce noise and offset sources present in the amplifier stage. The approach is applicable to a variety of contexts and applications. Example applications include, without limitation, detection of both brightness and Time of Flight (TOF) in 3D sensing applications. The approach may also be used to detect EM wave intensity in 2D sensing systems and, in general, for any application requiring simultaneously high speed and high sensitivity EM detection.
