  • Patent number: 10048145
    Abstract: A sensor assembly comprises a base plate and a sensor member displaceable relative to the base plate. A spring arrangement operates in first and second stages in response to displacement of the sensor member relative to the base plate. Different resolutions of force and torque measurements are associated with the first and second stages. A light sensitive transducer senses displacement of the sensor member relative to the base plate and generates corresponding output signals. A collimator directs a plurality of light beams onto the light sensitive transducer so that the light beams strike different pixels of the light sensitive transducer to sense displacement of the sensor member relative to the base plate.

  • Patent number: 9311255
    Abstract: The present invention relates to a microcontroller designed for protection of intellectual digital content. The microcontroller includes a secure CPU, a real-time cipher, and a user programmable multi-layer access control system for internal memory realized by programmable nonvolatile memory. Programmable nonvolatile memory allows in-system and in-application programming for the end user. The programmable nonvolatile memory is mainly used for program code and operating parameter storage. The multiple-layer access control is an integral part of the CPU, providing confidentiality protection to embedded digital content by controlling reading, writing, and/or execution of a code segment according to a set of user-programmed parameters. The cipher incorporates a set of cryptographic rules for data encryption and decryption with row and column manipulation for data storage. All cryptographic operations are executed in parallel with CPU run time without incurring additional latency and delay for system operation.

  • Publication number: 20150100500
    Abstract: A method of handling negotiations between a seller of an item and prospective buyers of the item is disclosed. A first offer for the item is received. The first offer includes a first item price and a first item quantity. A second offer for the item is received. The second offer includes a second item price and a second item quantity. It is detected that a first prospective buyer submitted a payment corresponding to the first offer before a second prospective buyer submitted a payment corresponding to the second offer. Based on an item quantity of the seller being less than the first quantity plus the second quantity, the seller is notified that the seller has an obligation to provide the first item quantity of the item to the first prospective buyer, but not the second quantity of the item to the second prospective buyer.
