Abstract: A wireless audio system using low overhead in-band control and audio transmission is provided. The wireless audio system includes a first wireless audio device configured to operate separate physical layer channels for audio data and control data, and transmit the audio data and control data using a single wideband carrier. The wireless audio system also includes one or more second wireless audio devices configured to receive the audio data and control data, and execute an instruction based on the control data.

Abstract: A method for synchronizing baseband clocks in an OFDMA wireless microphone system is disclosed. An example method includes receiving a plurality of pilot subcarriers from an audio transmitter. The method also includes determining a timing offset estimate based on the pilot subcarriers. The method further includes determining a tuning value by passing the timing offset estimate through a proportional-integral controller. The method still further includes determining a modified reference signal by modifying a reference oscillator based on the tuning value. And the method yet further includes controlling (i) an audio sample clock and (ii) an antenna data clock based on the modified reference signal.

Abstract: A snow removal system. The snow removal system includes a housing having an inlet disposed on a front side thereof, wherein the inlet is in fluid communication with a first chamber. An auger is disposed transversely across the first chamber, wherein the auger is operably connected to a motor within the housing. The auger rotates about a longitudinal axis thereof to mash snow and transport the mashed snow into a second chamber when the motor is actuated. The second chamber includes a primary heating element therein, the heating element designed to heat snow within the second chamber to produce steam. An outlet is disposed through a sidewall of the second chamber, wherein the outlet can emit steam from the second chamber.

Abstract: A wireless audio system including a transmitter using multiple antenna diversity techniques for different signal types is provided. Multipath performance may be optimized, along with improved spectral efficiency of the system.

Abstract: A wireless microphone system is disclosed. The system includes a plurality of wireless microphones each classified in accordance with one or more audio quality parameters. The system also includes a control device communicatively coupled to the plurality of wireless microphones. The control device is configured to determine that a first wireless microphone corresponds to a first audio classification, and that a second wireless microphone corresponds to a second, different, audio classification. The control device is also configured to determine a first modulation and coding scheme for the first wireless microphone based on the first audio classification, and a second modulation and coding scheme for the second wireless microphone based on the second audio classification. The control device is further configured to transmit, to the first and second wireless microphones respectively, the determined first and second modulation and coding schemes.

Abstract: A knotless tissue repair assembly for attachment of tissue to bone includes an anchoring implant with a length of suture threaded therethrough. The implant is preferably a soft flexible three-dimensional structure. The implant may be actuated from a first elongate low profile shape into a second short radially expanded shape having a larger diameter than the hole through which it was placed. The suture extends through the anchor, through a tissue to be secured, and back through a designated suture-binding region or passageway within the anchor enabling the suture to be secured therein and without the need for a physician to tie a knot. Further tension applied to a suture leg approximates the tissue to the anchor until a desired tension or distance between the tissue and anchor is achieved.

Abstract: A graft suspension device for suspending a ligament in a bone hole having a first loop and a second loop suspending from an 8-hole anchor, and a cradle at the opposite end of the loops to the anchor. The loose ends of the suture are routed through holes in the anchor separate from the loops and are joined together to form a single tail. A finger loop allows a surgeon to adjust the distance of the cradle from the anchor with the cradle staying centered with respect to the anchor as the distance is adjusted.

Abstract: A food product storage and vending kiosk includes a cold storage unit, an oven unit, and a transportation mechanism. The cold storage unit includes a plurality of food packages, an active shelving system storing the plurality of food packages, and a freezer. Each of the food packages includes a food product in a box. The oven unit includes a base oven deck for receiving the food product and rising to meet and seal with a main body to form a sealed oven cavity for cooking the food product. The transportation mechanism is for moving a food package out of the cold storage unit, onto an elevator platform that lifts the food package to the oven unit, pushing the food product from the box onto the base oven deck for cooking, and pushing the food product off of the base oven deck into the box and out of a delivery chute.
