Abstract: An information processing apparatus according to an embodiment of the present technology includes a control unit. The control unit detects, on a basis of an optical image of a cell in culture captured at a first imaging interval, whether there is a change in a state of the cell, and switches, when detecting the change in the state, an imaging mode from the first imaging interval to a second imaging interval shorter than the first imaging interval.

Abstract: A device for making EMC test measurement is provided, the device comprising a measurement cell configured as a mobile box. The box comprises an opening at one side, which may be opened and closed again at least partially, where the opening is configured such that a system to be inspected can be introduced into the interior of the box through it. The interior of the box is subdivided into two areas, a measurement device can be arranged in either one of the areas, and the system to be inspected can be arranged in the other area. The subdivision of the interior of the box into two areas results from a plate, wherein the plate comprises an absorber layer, a damping layer, or a shielding layer, in order to prevent disturbances of the system to be inspected by the measurement devices.

Abstract: Systems, methods, and apparatuses having an array of micro mirrors that rotate according to absorbed radiation and reflect light to generate light spots. In a first setting, a processor obtains an image of the light spots, determines positions of the light spots using a computationally efficient but less accurate method to calculate the intensities of radiation directed at the micro mirrors, and provides the calculated radiation. In a second setting, the processor does not determines the position; and the image is transmitted to a separate computing device to determine positions of the light spots using a computationally intensive but more accurate method to calculate the intensities of radiation directed at the micro mirrors. The system can dynamically switch between the first setting and second setting without a need to adjust hardware.

Abstract: The present disclosure is directed to a contrast phantom having a first region with a first reflection coefficient, a second region with a second reflection coefficient, and a third region with a third reflection coefficient, wherein the first reflection coefficient, the second reflection coefficient and the third reflection coefficient are increasing or decreasing in value in discrete steps, and wherein at least one of the regions includes an electrically conductive material having a thickness of about 200 μm. Methods of testing the contrast resolution of an active millimeter wave imaging system using the contrast phantom are also described.

Abstract: An air-conditioning control apparatus includes a detector that obtains a thermal image of an occupant, a processing unit that estimates the thermal sensation of the occupant from a temperature distribution obtained by the detector, and a control unit that controls an air conditioner according to the estimation result of the thermal sensation. Upon detecting the occupant, the detector captures a thermal image of an area around the occupant.

Abstract: A method of detecting concealed objects using a thermal imager includes obtaining an output comprising a plurality of pixels representing a person, analyzing each pixel matching a contour of the person and excluding any pixel within a blob bounding box of the person, and determining whether a pixel address is represented in a pixel map. In addition, the method includes comparing a value of each remaining pixel to an allowable minimum threshold value representing a lower pre-defined body temperature, and comparing the value of each remaining pixel greater than or equal to the allowable minimum threshold value to an upper allowable threshold value representing an upper pre-defined body temperature. The method also includes excluding any of the remaining pixels within a range between the lower and upper pre-defined body temperatures to define final set of pixels, and calculating a pixel difference to indicate a severity of the difference.

Abstract: Various techniques are provided for binning (e.g., clustering or grouping) two or more infrared sensors of a focal plane array (FPA) to permit configuration of the FPA to various dimensions and/or pixel sizes. For example, according to one or more embodiments, switchable interconnects may be implemented within the FPA, wherein the switchable interconnects comprise a plurality of switches adapted to selectively connect or disconnect infrared sensors of the FPA to/from column lines, row lines, and between each other. The switchable interconnects may also comprise another set of switches adapted to selectively connect adjacent column lines together. By selectively opening and closing appropriate switches of the switchable interconnects, two or more neighboring infrared sensors may be binned together to form a binned detector. Advantageously, the binned detector, along with the array and associated circuitry, may provide increased sensitivity, reduced power consumption, and/or increased frame rate.
