A shutter operation state monitoring method performed in a thermal imaging camera includes, controlling a shutter of the thermal imaging camera to be closed, capturing a first thermal image, calculating a correction offset value for the first thermal image, controlling the shutter to be opened, capturing a second thermal image, applying the correction offset value to the second thermal image, measuring a sound with a microphone when controlling the shutter to be closed and/or when controlling the shutter to be opened, determining whether the measured sound matches an operation sound of the shutter, and outputting an alarm indicating malfunction of the shutter if the measured sound does not match the operation sound.

Multi-modal, portable, handheld devices for tissue assessment (e.g., wound assessment) are provided, as are methods of fabricating and methods of using the same. The devices can be used for virtual medicine (VM)-based wound management, such as VM-based diabetic foot triage (DFT) and management. The device can be used to take physiological measurements of temperature and/or tissue oxygenation of a wound to assess the wound, for example in a remote setting environment. The device can also be used to provide therapy for tissue repair and/or wound healing, apart from the multi-modal imaging of the tissue surface of the patient. For example, light therapy, such as low-level light therapy (LLLT) can be provided via one or more light emitting diodes (LEDs) and/or laser diodes.

Techniques are provided for variable sensitivity in infrared imaging. In one example, an infrared imaging system includes an infrared imager and a logic device. The infrared imager is configured to capture a first infrared image of a scene using a sensitivity setting. The logic device is configured to determine a temperature associated with the scene based on a second infrared image of the scene. The logic device is further configured to determine the sensitivity setting based on an ambient temperature associated with the infrared imager and the temperature associated with the scene. Related devices and methods are also provided.

A system for monitoring brick in a rotary kiln includes an infrared sensor and a computing system configured to: obtain a digital model of a brick layer of a rotary kiln having a plurality of bricks, wherein the digital model of the brick layer is based on a measured brick thickness correlated with a measured infrared temperature for each brick; obtain infrared data of the rotary kiln with the at least one infrared imaging sensor; determine the measured infrared temperature for each brick; determine a brick thickness of a first brick in the brick layer of the rotary kiln based on the measured infrared temperature assigned to the first brick with the digital model of the brick layer; and provide the brick thickness of the first brick in a brick thickness report.

A targeting device for a firearm having a sighting device, the targeting device having a mount capable of being secured to the fire arm, and a camera capable of capturing images in a field of view including the sighting device, the camera being adjustable relative to the sighting device such that it can be aligned with the sighting device.

A thermal imaging device, comprising: a housing (3), which comprises a front housing (31); a lens mount (1), fixedly connected to the front housing (31), a sealing gasket (2) being provided between the front housing (31) and the lens mount (1); a lens (4), threaded with the lens mount (1); and a manual lens focusing structure, comprising a focusing wheel (8) and an axial positioning structure, wherein the focusing wheel (8) and the lens (4) are connected to each other in a synchronous rotation and relative axial movement mode, and the axial positioning structure implements axial positioning on the focusing wheel (8). In the process of focusing, the lens (4) axially moves with respect to the focusing wheel (8), and the focusing wheel (8) may not move axially due to the axial positioning structure.

A glazed element includes a vehicle glazing having an external main face intended to be oriented toward an exterior and an internal main face intended to be on a passenger compartment side, the glazing including a through-hole between the internal main face and the external face, the through-hole being delimited by a side wall of the glazing, and, in the through-hole, an insert made of material that is transparent in an LB range of wavelengths in an infrared spectrum ranging at least from 9.5 μm to 10.5 μm, the insert being made of material of refractive index n in the LB range, with an interior face and an exterior face, wherein the interior and exterior faces of the insert form a non-zero angle at an apex A, the insert having a thickness e that is variable and decreasing toward an upper edge of the glazing.
