  • Lead-free photodetector and method for manufacturing the same
    Patent number: 12260999
    Abstract: Disclosed are a lead-free photodetector and a method for manufacturing the same. The lead-free photodetector includes a light-side electrode, a light-side conductive layer formed on the light-side electrode, a perovskite layer formed on the light-side conductive layer, a rear-side conductive layer formed on the perovskite layer, and a rear-side electrode formed on the rear-side conductive layer.

  • REAR SEAT APPARATUS FOR VEHICLE
    Publication number: 20250091493
    Abstract: A rear seat apparatus for a vehicle includes a back frame and a cushion frame. The back frame is not interlocked with the cushion frame and is individually rotated in the forward-and-rearward direction independently of the cushion frame. The cushion frame is not interlocked with the back frame and individually slides in the forward-and-rearward direction independently of the back frame. A front seating state and a rear seating state of a passenger are implemented through individual sliding movement of the cushion frame in the forward-and-rearward direction.

  • POWER-EFFICIENT MIXED-SIGNAL CIRCUIT INCLUDING ANALOG MULTIPLY AND ACCUMULATE ENGINES
    Publication number: 20250077804
    Abstract: A first circuit is configured to split a first integer value into a first coarse value and a first fine value, and split a second integer value into a second coarse value and a second fine value. A second circuit performs an analog multiply and accumulate (MAC) operation on the first and second coarse values to produce a first analog output, perform an analog MAC operation on the first coarse value and the second fine value to produce a second analog output, perform an analog MAC operation on the first fine value and the second coarse value to produce a third analog output, and perform an analog MAC operation on the first and second fine values together to produce a fourth analog output. A third circuit is configured to perform analog-to-digital (A/D) conversion on and combine the analog output signals to produce a reconstructed digital output signal.
