  • Publication number: 20240118149
    Abstract: A stretchable strain sensor includes a light-emitting element, an optical structure, and a photo-detective element. The stretchable strain sensor is located in a path of light emitted from the light-emitting element. The optical structure is configured to have optical properties that change in response to stretching of at least a portion of the stretchable strain sensor. The photo-detective element is configured to detect light transmitted through the optical structure or reflected through the optical structure.

  • Patent number: 5918252
    Abstract: A method and apparatus for generating a modulo address for accessing a circular buffer. The method and apparatus accept as inputs a length L of the circular buffer, a current address A of the circular buffer, and an offset M between the current address and the next address to be generated. The offset M may be positive or negative. During operation of the present invention, the current address A first is broken down into a base address B and an offset from the base address a. Then, in accordance with the length L and the offset M, the invention determines an absolute offset and a wrapped offset. One of these offsets is added to the base address B to generate a next address for the circular buffer. The determination of which offset to add to the base address B is made by performing one of two comparisons.

  • Patent number: 5365460
    Abstract: An apparatus and method using a neural network processor for target detection is described. An array of injection mode infrared detectors, whose output signals convey intensity change information of detected objects in a pulse train output form is combined with a frequency division multiplexer to apply the information to a minimum number of multiplexed channels, and transmit the detector output signals to the processor in a continuous mode. A multi-layer neural network processor is used to localize global information and concentrate on areas of interest through matrix transformation applied by the various neural layers.
