Abstract: A method and system for daisy chaining tournament audio controllers, where the method comprises, in a headset coupled to a first audio controller, the first audio controller being in a daisy chain of audio controllers: receiving a chat signal from a previous audio controller in the daisy chain of audio controllers, receiving a microphone signal from a microphone in the headset, summing the chat signal with the microphone signal, communicating the summed signal to a next audio controllers in the daisy chain, and communicating the chat signal to the headset. The microphone signal may be removed from the summed chat signal and microphone signal by adding a second microphone signal 180 degrees out of phase with the microphone signal. The chat signal may be summed with the microphone signal at an amplitude set by a user of the headset after the removal of the microphone signal.

Abstract: A method and system for daisy chaining tournament audio controllers, where the method comprises, in a headset coupled to a first tournament audio controller (TAC), the first TAC being in a daisy chain of TACs: receiving a chat signal from a previous TAC in the daisy chain of TACs, receiving a microphone signal from a microphone in the headset, summing the chat signal with the microphone signal, communicating the summed signal to a next TAC in the daisy chain, and communicating the chat signal to the headset. The microphone signal may be removed from the summed chat signal and microphone signal by adding a second microphone signal 180 degrees out of phase with the microphone signal. The chat signal may be summed with the microphone signal at an amplitude set by a user of the headset after the removal of the microphone signal.

Abstract: A method and system for a passive headset with dynamically controlled LEDs, where the method comprises, in a passive headset comprising speakers, light emitting diodes (LEDs), and LED driver circuitry: receiving an electrical signal that includes an audio signal and an LED control signal, filtering out the LED control signal from the received electrical signal and communicating a resulting output audio signal to the speakers, filtering out the audio signal from the received electrical signal and communicating a resulting output LED control signal to the LED driver circuitry, generating a bias voltage for each of the one or more LEDs utilizing the LED driver circuitry and the output LED control signal, and configuring a light output of the LED utilizing the generated bias voltage. The amplifier may include a mixer that sums an audio signal with a control signal.

Abstract: A headset accessory comprises circuitry and is configured to mechanically attach to an audio headset. The circuitry of the headset may be operable to establish a link to the audio headset that supports conveyance of bias voltage, bias current, and/or information between the circuitry of the accessory and circuitry of the audio headset. The headset accessory may be configured to attach to a housing of the headset on a surface of the housing opposite an ear cup. A state of the circuitry of the accessory may be controlled based on the information received from the audio headset via the link. The information may include characteristics of audio being processed by the audio headset. The circuitry of the headset accessory may comprise non-volatile memory, and the non-volatile memory may store parameter settings for configuring audio processing circuitry of the audio headset.

Abstract: A snow throwing machine including a housing, an engine, an impeller and an auger for collecting snow and directing it to the impeller. The auger including an auger shaft disposed transversely in the housing and drivable by the engine, and a plurality of flytes mounted on the auger shaft. Each flyte includes a hub and a plurality of fins and is mounted on the auger shaft with a shear pin extending through the hub and auger shaft. The flytes are configured such that an outer peripheral edge of adjacent flytes forms a helix around the auger shaft directing snow toward the impeller.
