Abstract: A sensor device has a metal sensor housing with a housing base coupled to a frame base of a metal optical frame. A device mounting plate is orthogonal to the frame base. A securing device secures an optical communication device to the device mounting plate. A barrel mounting channel has first and second sidewalls, each extending obliquely to the frame base and defining a linear translation pathway along the frame base for a metal lens barrel. A fastener secures the metal lens barrel to the first and second sidewalls. A glass lens is in contact with three protrusions extending outward from an inner annular surface of the lens barrel. The optical communication device is configured to be in optical communication with the lens and is secured in a particular position in a translation plane mutually defined by the device mounting plate and the optical communication device.

Abstract: A foreign object detecting system and a method are provided. A control circuit controls a light transmitter and a light receiver. The light transmitter is disposed adjacent to a detected object and emits a light signal toward the detected object. The light receiver is disposed adjacent to the detected object in a path along which the light signal reflected by the detected object travels. The light receiver receives the light signal reflected to the light receiver. In a pre-operation, the control circuit defines the light signal received by the light receiver when the foreign object is not on the detected object as a first reflected light signal. In a detection operation, the control circuit determines that a difference exists between the light signal currently received by the light receiver and the first reflected light signal, the control circuit determines that the foreign object is on the detected object.

Abstract: An illumination device and method are provided herein for calibrating individual LEDs in the illumination device to obtain a desired luminous flux and a desired chromaticity of the device over changes in drive current, temperature, and over time as the LEDs age. The calibration method may include subjecting the illumination device to a first ambient temperature, successively applying at least three different drive currents to a first LED to produce illumination at three or more different levels of brightness, obtaining a plurality of optical measurements from the illumination produced by the first LED at each of the at least three different drive currents, obtaining a plurality of electrical measurements from the photodetector and storing results of the obtaining steps within the illumination device to calibrate the first LED at the first ambient temperature. The plurality of optical measurements may generally include luminous flux and chromaticity, the plurality of electrical measurements may generally include induced photocurrents and forward voltages, and the calibration method steps may be repeated for each LED included within the illumination device and upon subjecting the illumination device to a second ambient temperature.
