  • Patent number: 11669833
    Abstract: Quantum security may be enhanced through the use of quantum-safe validators for transactions whereby the quantum-safe validators process quantum-safe addresses and signatures of parties to the transactions. Quantum safety may be added to conventional blockchain transactions, for example, via smart contracts which are executed using cryptographic interlocks to between conventional smart contract execution engines and quantum-safe validators to ensure both quantum-safe processing of addresses and signatures and legitimacy of quantum-safe validators in presenting transactions for incorporation on the chain.

  • Patent number: 10678494
    Abstract: Systems and methods for using distributed Universal Serial Bus (USB) host drivers are disclosed. In one aspect, USB packet processing that was historically done on an application processor is moved to a distributed USB driver running in parallel on a low-power processor such as a digital signal processor (DSP). While a DSP is particularly contemplated, other processors may also be used. Further, a communication path is provided from the low-power processor to USB hardware that bypasses the application processor. Bypassing the application processor in this fashion allows the application processor to remain in a sleep mode for longer periods of time instead of processing digital data received from the low-power processor or the USB hardware. Further, by bypassing the application processor, latency is reduced, which improves the user experience.

  • Patent number: 10639204
    Abstract: A navigation and monitoring system to track positions of surgical components during surgery of a patient. Some embodiments include a power source to emit a tracking signal during surgery of the patient, a first sensor mounted to a region of the patient to respond to the emitted tracking signal, and a control unit to track a position of the region relative to a fixed region of the patient as the region moves with respect to the fixed region, based on the response of the first sensor. The system can calibrate and register a movable reference point of the patient relative to a fixed reference point, and can maintain that reference point when the movable reference point moves in space during a surgical process.

  • Publication number: 20190209802
    Abstract: A humidifier includes a base configured to retain a body of liquid therein, a top cover, and a seal disposed between the top cover and the base. At least a portion of the base is constructed of a heat conducting material. The top cover defines both an inlet and an outlet communicated with an interior of the base. The inlet is configured to receive pressurized breathable gas and the outlet is configured to deliver the pressurized breathable gas with added humidity.

  • Publication number: 20170373881
    Abstract: Systems and methods for controlling isochronous data streams are disclosed. Particular aspects of the present disclosure are designed to be used with almost any isochronous data stream, but are well-suited for use with the Universal Serial Bus (USB) protocol. Further, aspects of the present disclosure are flexible to accommodate existing configuration possibilities within the USB protocol as well as accommodate proposed future changes in the USB protocol. The flexibility of the systems and methods is provided by calculating: (1) drift between a USB host system time and the application and (2) drift between the USB host system and a USB device clock. Based on these two drift calculations, a time stamp may be synthesized to program a next delivery schedule. Using this time stamp, jitter correction can take place and uniformly-sized packets may be assembled to pass to an application processor.
