    摘要: Techniques are disclosed for facilitating multiple microbolometer selection for simultaneous readout. In one example, a device includes a plurality of microbolometers. The plurality of microbolometers includes a first set and a second set of serially-connected microbolometers. The device further includes a first plurality of switches configured to selectively short the plurality of microbolometers. The device further includes a second plurality of switches configured to selectively couple the plurality of microbolometers to ground. The device further includes a third plurality of switches configured to selectively provide a bias signal to the plurality of microbolometers. The device further includes a processing circuit configured to configure the first plurality, second plurality, and third plurality of switches to cause simultaneous read out of one microbolometer of the first set and one microbolometer of the second set. Related methods and systems are also provided.

    摘要: A highly visible overlay system may include a display system and contrasting visible element configuration components configured to define contrasting visible elements. An imaging component is configured to capture an image of a target scene for display. A processing component is configured to construct the plurality of contrasting visual elements in accordance with a visual acuity factor, and generate an electronic overlay constructed of the contrasting visual elements. A display component is configured to display the constructed overlay in combination with the image of the target scene, with the overlay being displayed as an overlay on the image of the target scene. The contrasting visual elements may include a white block and a black block, configured to satisfy visual acuity factor, display configuration and field of view information.

    摘要: Systems and methods are directed to vertical legs for an infrared detector. For example, an infrared imaging device may include a microbolometer array in which each microbolometer includes a bridge and a vertical leg structure that couples the bridge to a substrate such as a readout integrated circuit. The vertical leg structure may run along a path that is parallel to a plane defined by the bridge and may be oriented perpendicularly to the plane. The path may be disposed within, below, or above the plane defined by the bridge.

    摘要: Techniques are disclosed for systems and methods to provide proactive directional control for a mobile structure. A proactive directional control system may include a logic device, a memory, one or more sensors, one or more actuators/controllers, and modules to interface with users, sensors, actuators, and/or other modules of a mobile structure. The logic device is adapted to determine a steering angle disturbance estimate based on environmental conditions associated with the mobile structure, and the steering angle disturbance estimate is used to adjust a directional control signal provided to an actuator of the mobile structure. The logic device may also be adapted to receive directional data about a mobile structure and determine nominal vehicle feedback from the directional data, which may be used to adjust and/or stabilize the directional control signal provided to the actuator.

    摘要: Techniques are disclosed for facilitating pulse detection and imaging. In one example, a device includes a detector configured to detect electromagnetic radiation and generate a detection signal based on the detected electromagnetic radiation. The device further includes an input circuit configured to provide, based on the detection signal, a first signal and a second signal. The device further includes an imaging integration circuit configured to generate an image of at least a portion of a scene based at least in part on the first signal. The device further includes a pulse detection circuit configured to perform pulse detection to generate an indication of whether a pulse is detected in the portion of the scene based at least in part on the second signal. Related methods and systems are also provided.

    摘要: Various techniques are provided to process captured thermal images to determine whether the thermal images exhibit degradation associated with environmental effects and/or security conditions. In one example, a method includes capturing a plurality of thermal images of a scene. The thermal images are processed to generate first and second background images associated with first and second time periods to filter out changes in the scene occurring within the associated time periods. The first and second background images are edge filtered to generate first and second edge images. The first and second edge images are compared to determine a change in edges associated with the scene. A device is selectively operated in a fail-safe mode in response to the comparing. Additional methods and related systems are also provided.
