Abstract:
A sensor arrangement comprises at least a first, a second, and a third light sensor. A three-dimensional framework comprises at least a first, a second, and a third connection means which are connected to the at least first, second, and third light sensor, respectively. The first, the second, and the third connection means are configured to align the at least first, second, and third light sensor along a first, second, and third face of a polyhedron-like volume, respectively, such that the sensor arrangement encloses the polyhedron-like volume. The invention also relates to a method for operating the sensor arrangement.

An apparatus and method for detecting an intensity of radiation in a process chamber, such as an ultraviolet curing process chamber, is disclosed. An exemplary apparatus includes a process chamber having a radiation source therein, wherein the radiation source is configured to emit radiation within the process chamber; a radiation sensor attached to the process chamber; and an optical fiber coupled with the radiation source and the radiation sensor, wherein the optical fiber is configured to transmit a portion of the emitted radiation to the radiation sensor, and the radiation sensor is configured to detect an intensity of the portion of the emitted radiation via the optical fiber.
Abstract:
A liquid crystal display (LCD) includes a graphic processor, a number of sensors, an optical signal collecting unit, a property saving unit, a property comparing unit, and a property setting unit. The optical signal collecting unit receives optical analog signals generated by the number of sensors, and converts the received optical analog signals into optical digital signals. The property saving unit saves a number of predetermined display properties and a number of predetermined optical signal ranges. The property comparing unit receives the optical digital signals and compares the optical digital signals with the plurality of predetermined optical signal ranges, and correspondingly selects corresponding predetermined display properties. The property setting unit receives the selected display properties and outputs the selected display properties to the graphic processor to adjust display properties of the LCD.

Abstract:
A light sensor assembly 10 and a method for detecting ambient light 100 which logarithmically amplifies a first signal which is representative of the certain amount of sensed light and a second offset signal and which adds the logarithmically amplified signals to a voltage signal, thereby allowing an accurate signal to be produced which indicative of the sensed amount of light by use of only a positive type electrical power supply and which is effective to allow the output signal to fall within the relatively narrow operating range of a cost effective digital to analogue converter.
Abstract:
The specific disclosure provides a device which includes a circuit having a pair of phototransistors. One of the phototransistors senses the amount of light transmission from a light source through an oil chamber. The other phototransistor is in direct optical communication with the light source, and generates a signal in response to ambient temperature which is used as a basis for adjusting the intensity of light emitted by the light source. A diminution of light transmission through the chamber is indicative of a degradation of the oil therein.
