  • Patent number: 11147895
    Abstract: A CPAP equipment sanitizing system that includes an oxidizing gas generator, a sanitizing chamber and tubing. The oxidizing gas generator has an outlet port. The sanitizing chamber includes an enclosure, a fitting and a closure mechanism. The enclosure has an opening. The enclosure is adapted to receive CPAP equipment. The enclosure has an aperture formed in a surface thereof. The fitting that extends through the aperture and sealingly engages the sanitizing chamber. The closure mechanism is capable of substantially closing the opening. The tubing operably attaches the outlet port on the oxidizing gas generator and the fitting.

  • Patent number: 10751592
    Abstract: A peripheral visual training system using a peripheral visual trainer that includes an orientation monitor operably mounted on an athlete's head or an a helmet that is secured to the athlete's head as the athlete participates in an activity to help the athlete develop his or her peripheral vision by alerting the athlete through an alarm to concentrate on using peripheral vision rather than central vision when the peripheral visual trainer detects the athlete is using central vision for an object that should be viewed using peripheral vision.

  • Patent number: 8335272
    Abstract: A MIMO transmitter has a modulator (40,41,42, 120, 122) a demultiplexer 100 arranged to divide the information into one or more demux streams for transmission over different ones of the channels, and a diversity splitter (110) to derive one or more sub-streams of the same information. A decorrelator (120) such as a scrambler (150, 155) decorrelates the sub-streams before or after the modulation. The arrangement is configurable to vary in use a ratio of demultiplexing and of diversity splitting. This balances between the gains from diversity and spatial multiplexing, without needing major changes to the transmit and receive processing.

  • Patent number: 7819957
    Abstract: An operating room filter system connectable to a surgical body gas evacuator, such as a trocar, that includes a carbon monoxide filter media that removes carbon monoxide from a surgical waste gas. In addition, the inclusion of further filter media upstream of the carbon monoxide filter media inhibits the saturation of the carbon monoxide filter media to thereby provide an extended life to the filtration system.
