Abstract: Provided is a device for visualizing a temperature and an amount of static electricity, wherein the device is arranged adjacent to a substrate processing liquid providing unit including a pipe to provide a passage through which a substrate processing liquid is transferred and a processing liquid storage module for storing the substrate processing liquid, the device including a photographing unit configured to generate a plurality of partially captured images by photographing a plurality of areas of a measurement target, a static electricity sensor configured to measure static electricity levels of the plurality of areas of the measurement target, a thermal imaging camera configured to measure temperatures of the plurality of areas of the measurement target, a processor configured to generate an entire image by combining the plurality of partially captured images with each other, and an output unit configured to output a visualization image.

Abstract: Input light comprising an optical signal associated with a spectrum of at least a portion of the input light is received into an interferometer. Data comprising an image is provided using a detector array comprising detection elements. Output light is received from the interferometer into a set of one or more optical elements, which provide an optical interference pattern associated with an intensity of at least a portion of the output light that is distributed over a set of detection elements. Detection of the optical signal is stabilized based at least in part on the data using a control system comprising: a light-control module that controls a first feedback loop that stabilizes the portion of the output light; and/or a temperature-control module that controls a second feedback loop that stabilizes a temperature sensed by at least one temperature sensor within a thermal environment associated with the interferometer.

Abstract: A mouse pad with improved self-cleaning and traction features. The mouse pad is a planar structure with a parallel top control layer and a bottom anti-skid coating. Formed on the top layer is a top control layer with a plurality of alternating, equal height, prismatic and pyramidal shapes, which provide improved cleaning and traction properties. Small troughs are formed between the adjacent shapes, which collect fine dirt and dust particles that are swept from the surface of the mouse ball during use. In one embodiment, the top control surface is made of flexible material that allows the prismatic and pyramidal shapes to bend slightly when the ball of a mechanical mouse rolls over the top surface. This bending action provides improved self-cleaning and traction features. In another embodiment, the top layer is made of transparent material. An ink layer may be applied to the bottom surface of the top layer.
