  • Patent number: 11143847
    Abstract: A compact, small form factor optical system for cameras that provides multiple optical paths to capture images of an object field in different portions of the light spectrum. The optical system includes a front lens group that captures visible and near-infrared (NIR) light from an object field and refracts the light to a beam splitter that splits the visible light and the NIR light onto two paths. On the visible light path, a visible light lens group refracts the visible light to form an image of the object field at a visible light sensor. On the NIR light path, a NIR light lens group refracts the NIR light to form an image of the object field at an NIR light sensor. The optical system thus provides images of the object field at two sensor planes, one image in the visible spectrum and the other image in the NIR spectrum.

  • Patent number: 11131721
    Abstract: The semiconductor device includes a Hall element, a first differential pair, a second differential pair, an output amplifier circuit, and a voltage divider circuit. The Hall element outputs a signal that is dependent on stress to be applied to a semiconductor substrate to the first differential pair. The voltage divider circuit divides a voltage into a divided voltage having a voltage dividing ratio that is dependent on the stress. The first differential pair outputs a first current based on the signal. The second differential pair outputs a second current based on the divided voltage and a reference voltage. The output amplifier circuit outputs a voltage based on the first and second currents. A gain of the output amplifier circuit is approximated by a sum of a difference between stress dependence coefficients of transconductances of the first and second differential pairs and a stress dependence coefficient of the voltage dividing ratio.

  • Patent number: 10754142
    Abstract: Systems are provided including night vision goggles and up-conversion circuits for converting short wave infrared (SWIR) light into near infrared (NIR) light or other visible light in low-light environments. An array of electrically coupled photodiodes, amplifiers, and NIR light emitters generate and amplify a current in response to SWIR, powering the light emitters to generate NIR light. The NIR can then be directed into a photomultiplier tube to amplify the light and allow an operator to see in low-light environments.
