  • Patent number: 10553020
    Abstract: A method can include determining, based on elevation data of a geographic region corresponding to a location at which an image was captured and a solar elevation angle at a time the image was captured, whether each pixel of the image is a shadow or a non-shadow to create a shadow mask of the image, generating an eroded shadow mask that includes the shadow mask with a specified number of pixels from a perimeter of each shadow in the shadow mask changed to respective values corresponding to non-shadows, generating a dilated shadow mask that includes the specified number of pixels in the shadow mask changed to values corresponding to shadows, and refining the shadow mask using the eroded shadow mask and the dilated shadow mask to create a refined shadow mask.

  • Patent number: 10411744
    Abstract: A method for transforming and reconstructing a signal includes receiving a plurality of samples of a waveform of the signal at different points in time. The waveform of the signal is transformed, for each sample, into an in-phase (I) component and a quadrature (Q) component. A derotational circuit applies a delayed complex conjugate multiple (DCM) to the signal to determine a constant product having an I component (Ic) and a Q component (Qc). A magnitude component is determined based on Ic and Qc. A delta phase component is determined based on Ic and Qc. The magnitude component is processed to create a processed magnitude component. The delta phase component is processed to create a processed delta phase component. An IQ waveform is created by reconstructing the waveform of the signal based on the processed magnitude component and the processed phase component.

  • Patent number: 8896701
    Abstract: An active infrared sensor may include an imaging infrared sensor to provide an output signal conveying time-sequential infrared images of a scene which includes a subject, a beam generator to generate a millimeter wave energy beam, and a processor. An initial infrared image of the scene may be stored in a memory. After storing the initial infrared image, the beam generator may illuminate the subject with the millimeter wave energy beam. A temperature change across the subject due to the millimeter wave energy beam may be estimated based on the output signal and the stored initial infrared image. The beam generator may stop illuminating the subject when a highest temperature change across the subject is at least equal to a predetermined temperature change limit.

  • Patent number: 7178345
    Abstract: A gas-expansion cooler assembly has an expansion structure with an expansion orifice and an expansion reservoir in fluid-flow communication with an expansion-orifice outlet. A heat exchanger has a heat-exchanger inlet, and a heat-exchanger outlet in fluid-flow communication with the expansion-orifice inlet. The heat exchanger includes at least two heat-exchanger plates stacked in a facing relationship along an assembly axis. Each heat-exchanger plate includes an in-plane channel lying substantially in a plane perpendicular to the assembly axis. The in-plane channels of the adjacent heat-exchanger plates are in fluid-flow communication with each other and with the expansion-orifice inlet to form a continuous high-pressure fluid-flow path from the heat-exchanger inlet to the expansion-orifice inlet. The heat exchanger further includes an axial channel extending parallel to the assembly axis.

  • Patent number: 5347360
    Abstract: A ring laser gyro uses means for shaping the gas flow, which inevitably develops as a result of a DC discharge, to optimize the effect of the Fresnel-Fizeau drag on the output signal of the gyro. In one embodiment, a sufficient component of the gain medium flow is provided to produce a substantially constant Fresnel-Fizeau component of the output signal even in the presence of variations of the discharge current. In another embodiment, a sufficient component of gain medium flow is provided to substantially eliminate the Fresnel-Fizeau component of the output signal at a predetermined level of discharge current.
