Abstract: A drive circuit includes a switch controller, a first monitor, a second monitor, and a safety controller. The switch controller can selectively control a light-emitter apparatus to emit light and stop emitting the light. The first monitor can monitor light-emitting energy of the light-emitter apparatus. The second monitor can monitor a light-emitting duration of the light-emitter apparatus. The safety controller can control the light-emitter apparatus to stop emitting the light by a switch controller in response to at least one of the light-emitting energy reaching a first threshold or the light-emitting time reaching a second threshold.

Abstract: A light detector comprising: an array of photodetectors for receiving light signals and generating electrical signals corresponding to the light signals, an array of switches comprising a plurality of first switches, each of the plurality of first switches couples to a respective one of the array of photodetectors, and each of the plurality of first switches is configured to control an operating state of the respective one of the array of photodetectors for a signal output terminal of the respective one of the array of photodetectors to output the electrical signals, and a selector configured to select the respective one of the array of photodetectors in the operating state to output the electrical signals.

Abstract: This invention relates to a method for synthesizing polyoxymethylene on a substrate. The method includes depositing monomer capable of forming polyoxymethylene by an initiated polymerization reaction and an initiator, via initiated chemical vapor deposition (iCVD) onto a surface of a substrate in an initiated chemical vapor deposition reactor.
