Abstract:
A security device including a Fresnel lens covering the entire face of the device, a housing, and a pyroelectric detector is disclosed. The center portion of the Fresnel lens which contains the Fresnel lens elements is molded flat, it's edges are molded in the final installed form and its edges contain appendages that secure the lens on the device so there are no gaps between the lens and the device.
Abstract:
The present disclosure is directed to a method for detecting a condition associated with a wheel bearing on a train car. The method may include detecting a size and a location of the wheel bearing. The method may also include detecting a temperature associated with the wheel bearing based at least in part on the size and the location of the wheel bearing. The method may further include determining a wheel bearing condition based on the detected temperature.
Abstract:
What is disclosed is a system and method for assessing peripheral vascular disease from a thermal image captured using a thermal imaging system. In one embodiment the present method involves the following. First, a thermal image is received of a region of exposed skin of a peripheral body part of a subject being monitored for PVD. The thermal image was acquired by a thermal imaging system. Pixels in the thermal image each have a corresponding temperature value. The thermal image is analyzed to stratify the peripheral body part into a plurality of skin surface regions. A skin surface temperature for each respective skin surface region is identified based on pixels in the thermal image associated with those regions. The temperatures are then extracted such that a progression of temperatures can be ascertained. A method for forecasting the progression for future times is also disclosed.

A thermal imaging system with a vacuum-sealing lens cap, includes (a) a thermal image sensor having an array of temperature sensitive pixels for detecting thermal radiation, and (b) a lens sealed to the thermal image sensor for imaging thermal radiation from a scene onto the array of temperature sensitive pixels and sealing a vacuum around the temperature sensitive pixels. A wafer-level method for manufacturing a thermal imaging system with a vacuum-sealing lens cap includes sealing a lens wafer, having a plurality of lenses, to a sensor wafer having a plurality of thermal image sensors each having an array of temperature sensitive pixels, to seal, for each of the plurality of thermal image sensors, a vacuum around the temperature sensitive pixels.
Abstract:
A system for interacting with a thermal detector includes at least one unmanned aerial vehicle and a sensor mounted to the at least one unmanned aerial vehicle. The sensor is configured to determine the presence of a component of the thermal detector and to generate a signal indicative of the presence of the component. The system also includes a beam emitter mounted to the at least one unmanned vehicle and in communication with the sensor. The beam emitter includes a beam source configured to direct a beam of thermal radiation to the thermal detector in response to the signal from the sensor.
Abstract:
A structure for detecting electromagnetic radiation having a predetermined wavelength. The structure includes a device wafer having a sensing element disposed on a predetermined region of a surface of the device wafer responsive to the electromagnetic radiation.

Abstract:
A thermal imaging camera monitors the temperature different zones in a pharmaceutical process such as ribbon compaction, coating, spray drying, fluid bed drying, high shear wet granulation, crystallization, lyophilization, precipitation, fermentation, and low dosage dispensing of a pharmaceutically active liquid. The thermal imaging camera can be used to produce a visual display of a temperature profile, or a spray pattern. In addition, feedback from the thermal imaging camera is used to control one or more processing parameters.

Abstract:
The present invention relates to a method and system for monitoring and controlling a glass container forming process. The radiation emitted by each hot glass container is measured with measurement unit immediately after the forming machine. The described method normalizes the measurement from glass container to glass container and thereby removes the effects of overall temperature variations between glass containers, changing ambient conditions, and other variations affecting the measurements, which provides a unique quality reference for each glass container. By reviewing this reference for each produced glass container, the quality of the produced containers can be improved.
