Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.

Abstract: Various embodiments related to monitoring for optical faults in an optical system are disclosed. For example, one disclosed embodiment provides, in an optical system comprising a light source, a light outlet, and an optical element disposed between the light source and the light outlet, a method of monitoring for optical system faults. The method includes detecting, via a light sensor directed toward an interface surface of the optical element closest to the light source, an intensity of light traveling from the interface surface of the optical element to the light sensor, and comparing an intensity of light detected to one or more threshold intensity values. The method further includes identifying an optical system fault condition based on comparing the intensity of light detected to one or more threshold values, and modifying operation of the optical system.

Abstract: Technology for detecting a change in a configuration position of one or more elements in an illumination system is described. A light source generates an illumination signal, and an element of the system directs a portion of the light of the signal back to a light detector. In one example, the portion of light is reflected back to the light detector. By monitoring an output signal of the light detector based on the directed light, control circuitry can detect that a position of an element of the system has changed. In one example, an off-the-shelf integrated circuit laser diode package including a monitor photodiode can be used with a reflective element. In one example, the reflective element is a tilted optical element. Changes can be detected in the configuration of one or more optical elements of the illumination system which are outside the laser diode package.

Abstract: An optical sensor for detecting motion or movement in an area of interest and a method of operation is provided. The system includes a CMOS sensor having an array of pixels that captures images in an area of interest. The system monitors the average pixel value for the array to define a first state. If the average pixel value changes beyond a defined threshold, the system defines a second state. For each change in state, a signal is generated. In one embodiment, the optical sensor is used with a meter having a dial with an indicator. The optical sensor generates a signal each time the indicator passes through the area of interest to allow for the remote monitoring of a consumable commodity.
