  • Operating room safety zone
    Patent number: 10265854
    Abstract: Methods and devices for identifying and defining a safety zone for restricting movement of a robotic arm in an operating room during a medical procedure are disclosed. The disclosed method utilizes medical navigation system, which receives an initiation input indicating initiation of defining of the safety zone. In response to receiving the initiation input, the system tracks an instrument and determines the location of the tracked instrument relative to a reference point. The system detects changes in the location of the tracked instrument until a termination input is received at the medical navigation system. The termination input indicates the termination of the defining of the safety zone. The system stores, in memory, change data indicative of the changes in the location of the tracked instrument. The data identifies the safety zone relative to the reference point.

  • Enabling RX signal path synchronization and alignment signals in a highly integrated TX RFIC
    Patent number: 10270583
    Abstract: A transmit (TX) signal path circuit in a multiple-input, multiple-output (MIMO) transceiver responsive to a digital front end (DFE) for generating receive (RX) path phase alignment signals is disclosed. A digital up-conversion block uses a first numerically-controlled oscillator (NCO) for generating digital intermediate frequency (IF) signals for ordinary TX signal generation, and a different, second NCO for generating digital IF signals for RX phase alignment signal generation. An RF up-conversion block uses a TX local oscillator (LO) for generating analog RF signals for ordinary TX signal generation, and a different feedback (FB) LO for generating analog RF signals for RX phase alignment signal generation. Thus, phase alignment of the circuitry used for ordinary TX signal generation is left undisturbed by RX phase alignment signal generation.

  • Producing high-purity chlorine dioxide gas
    Patent number: 10266406
    Abstract: A high-purity chlorine dioxide gas may use hydrogen peroxide as a reducing agent and may use horizontal generator, evaporation crystallizer, dryer and other devices to produce chlorine dioxide gas (product) and sodium sulfate (by-product). Compared to the conventional chlorine dioxide preparation system, the chlorine dioxide reaction and the sodium sulfate crystallization are performed in two processes. These processes are relatively separate and independent, and continuously produce chlorine dioxide gas with high purity and low moisture content while the by-product salt cake is evaporated, crystallized, filtered and dried, thereby producing sodium sulfate, without generating solid and liquid waste.
