摘要： A bolometer circuit may include an active bolometer configured to receive external infrared (IR) radiation and a resistive load, which are configured to be connected in series in a bolometer conduction path from a supply voltage node to a common voltage node. A node in the bolometer conduction path between the resistive load and the active bolometer is coupled to a first input of an op-amp. A variable voltage source is coupled to a second input of the op-amp to provide a reference voltage level. The op-amp maintains the reference voltage level at the first input to generate a current flow in response to a resistance change of the active bolometer due to the external IR radiation. The amplifier circuit may be configured as a feedback amplifier or an integrating amplifier. The bolometer circuit may be configured to enable a low-power mode of operation.

摘要： Various embodiments of the present disclosure may include an imaging system. The imaging system may include a controller that is adapted to determine behavior typical of an object within an environment. The imaging system may additionally monitor the object within the environment and detect when the object behaves anomalously within the environment. Upon detection of anomalous behavior, the controller may output an alarm and/or a response message.

摘要： Various techniques are provided for an infrared sensor assembly having a hybrid infrared sensor array. In one example, such a hybrid infrared sensor array may include a plurality of microbolometers and a non-bolometric infrared sensor. The non-bolometric infrared sensor may be a thermopile or other type of infrared sensor different from a bolometer-based sensor. The non-bolometric infrared sensor may be utilized to provide a more accurate and stable temperature reading of an object or area of a scene captured by the array. In some embodiments, the non-bolometric infrared sensor may also be utilized to perform a shutter-less radiometric calibration of the microbolometers of the array. An infrared sensor assembly may include, for example, the hybrid infrared sensor array, as well as a substrate including bond pads and/or appropriate circuits to obtain and/or transmit output signals from the non-bolometric infrared sensor.

摘要： Techniques are disclosed for systems and methods to provide accurate, low lag, and reliable autopilot autorelease in a hydraulic steering system for mobile structures. A hydraulic steering system includes a logic device configured to communicate with an autopilot pump controller, a control surface reference sensor, an orientation sensor, and/or a gyroscope. Control and sensor signals provided by the pump controller and/or the various sensors are used to selectively enable and/or disable an autopilot release signal. The autopilot release signal enables or disables the autopilot pump controller and/or an autopilot pump, or controls the autopilot pump controller to enable or disable the autopilot pump.

摘要： Techniques are disclosed for systems and methods to provide reliable analyte spatial detection systems. An analyte spatial detection system includes an imaging module, a visible light projector, associated processing and control electronics, and, optionally, orientation and/or position sensors integrated with the imaging module and/or the visible light projector. The imaging module includes sensor elements configured to detect electromagnetic radiation in one or more selected spectrums, such as infrared, visible light, and/or other spectrums. The visible light projector includes one or more types of projectors configured project visible light within a spatial volume monitored by the imaging module. The system may be partially or completely portable and/or fixed in place. The visible light projector is used to indicate presence of a detected analyte on a surface near or adjoining the spatial position of the detected analyte.

摘要： 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.

摘要： Techniques using small form factor infrared imaging modules are disclosed. An imaging system may include visible spectrum imaging modules, infrared imaging modules, and other modules to interface with a user and/or a monitoring system. Visible spectrum imaging modules and infrared imaging modules may be positioned in proximity to a scene that will be monitored while visible spectrum-only images of the scene are either not available or less desirable than infrared images of the scene. Imaging modules may be configured to capture images of the scene at different times. Image analytics and processing may be used to generate combined images with infrared imaging features and increased detail and contrast. Triple fusion processing, including selectable aspects of non-uniformity correction processing, true color processing, and high contrast processing, may be performed on the captured images. Control signals based on the combined images may be presented to a user and/or a monitoring system.

摘要： An improved emitter tracking system. In aspects of the present teachings, the presence of a desired emitter may be established by a relatively low-power emitter detection module, before images of the emitter and/or its surroundings are captured with a relatively high-power imaging module. Capturing images of the emitter may be synchronized with flashes of the emitter, to increase the signal-to-noise ratio of the captured images.

摘要： Various techniques are disclosed for bolometer circuits and related methods for thermal imaging in a difference domain, where each pixel value represents a difference in incident IR radiation intensity between adjacent bolometers. For example, a bolometer circuit may include an array of bolometers each configured to generate a pixel signal in response to a bias and incident infrared radiation. Each column of the bolometer array may comprise an amplifier, a first plurality of switches each configured to selectively provide a supply voltage to a respective one of bolometers of the each column, a second plurality of switches each configured to selectively route a difference of the pixel signals of a respective adjacent pair of the bolometers of the each column to an input of the amplifier, and a third plurality of switches configured to selectively provide a common voltage to a respective one of the bolometers of the each column.

摘要： Techniques are disclosed for systems and methods for providing accurate and reliable compact sonar systems for mobile structures. In one embodiment, a sonar system includes a mounting bracket, a transducer support arm, and a pivoting mechanism pivotably coupling the transducer support arm to the mounting bracket such that, for forces acting on the transducer support arm that are less than a preselected kick-up level, the pivoting mechanism holds the transducer support arm against such forces and at a user selectable first angular position relative to the mounting bracket, and for forces acting on the transducer support arm that are equal to or greater than the preselected kick-up level, allows the transducer support arm to be moved by those forces to a second angular position relative to the mounting bracket.
