  • Publication number: 20250151340
    Abstract: Systems, apparatuses, and methods provide for predicting a remaining useful life of semiconductors utilizing quantum sensors. A layer of 2-D material of the quantum sensor is excited via a microwave field source and a light source of a quantum sensor while also subject to a magnetic field, where the quantum sensor is located adjacent a semiconductor device. The excitation of the layer of 2-D material is sensed, via a photodetector of the quantum sensor. A magnetic field, a temperature, and/or a strain field effect of the semiconductor device are measured based on the sensed excitation of the layer of 2-D material. A remaining useful life of the semiconductor device is predicted based on one or more of the measured magnetic field, the measured temperature, or the measured strain field effect.

  • Patent number: 11972613
    Abstract: Apparatus and methods for determining an atmospheric condition in an environment of a vehicle are described herein. A long wave infrared camera may be used to produce thermal image data from a field of view of the LWIR camera that includes an unknown atmospheric condition. The thermal image data may include a characteristic that may be compared to characteristic of thermal image data for a known atmospheric condition. A result of the comparison may be used to make a determination related to the unknown atmospheric condition which may be used in controlling the vehicle.

  • Publication number: 20230177889
    Abstract: Techniques for determining a degraded state associated with a sensor are discussed herein. For example, a sensor associated with vehicle may captured data of an environment. A portion of the data may represent a portion of the vehicle. Data associated with a region of interest can be determined based on a calibration associated with the sensor. For example, in the context of image data, image coordinates may be used to determine a region of interest, while in the context of lidar data, a beam and/or azimuth can be used to determine a region of interest. A data metric can be determined for data in the region of interest, and an action can be determined based on the data metric. For example, the action can include cleaning a sensor, scheduling maintenance, reducing a confidence associated with the data, or slowing or stopping the vehicle.

  • Patent number: 11052510
    Abstract: The present invention is an imprint device for imprinting a unique identification mark on a surface of an object with imprinting particles of different sizes that increase uniqueness and without the need for electric power. The imprint device includes a vertical member, a hammer member, a trigger assembly, a charging unit, a barrel and at least one pocket. In the operative configuration, a trigger of trigger assembly is activated such that hammer member impacts a cartridge filled with at least one munition of imprinting particles and releases imprinting particles. The imprinting particles travel through the barrel where acceleration is increased and impact on surface is made to form microcraters and unique identification marks. The imprinting particles can be of same size, material and shape or they can be of different sizes, material and shapes or the combination thereof for increasing uniqueness.

  • Patent number: 10671906
    Abstract: The present invention is a method for analyzing an imprint configured on a surface of an object at a source location and verifying at a destination location to determine the object's authenticity. The method includes capturing at least one image at a source location and examining and analyzing the captured image. The analysis is performed by dividing the captured image into multiple layers. For each layer area, size, threshold points, distance between threshold points and angle of lines are determined and then stored in the first database. Afterwards this data is encrypted by a source user and uploaded to a blockchain. When the object reaches the destination location the destination user performs the same operation of capturing, examining and analyzing by dividing the captured image into multiple layers in the same fashion as performed by the source user and then stored in a second database.
