Wireless audio headset

A headset worn by workers in retail stores and similar commercial settings is disclosed. The headset includes an ornamental bezel. The bezel may be attached to the headset body to provide distinguishing characteristics to the headset.

Customizable headset

A device has a communication link, a headset, and an electronics module. The headset is connected to the communication link and has a speaker, and a microphone. The electronics module is connected to the communication link and has a housing with an information conveying tag positioned on a surface, a processor communicatively coupled to the headset through the communication link, a battery, and a wireless transceiver communicatively coupled with a remote terminal.

A self calibrating dipole microphone formed from two omni-directional acoustic sensors. The microphone includes a sound source acoustically coupled to the acoustic sensors and a processor. The sound source is excited with a test signal, exposing the acoustic sensors to acoustic calibration signals. The responses of the acoustic sensors to the calibration signals are compared by the processor, and one or more correction factors determined. Digital filter coefficients are calculated based on the one or more correction factors, and applied to the output signals of the acoustic sensors to compensate for differences in the sensitivities of the acoustic sensors. The filtered signals provide acoustic sensor outputs having matching responses, which are subtractively combined to form the dipole microphone output.

Electronic device

A meshing gear assembly includes a toothed disk that is supported on a first gear so as to be frictionally engaged therewith, but rotationally and radially movable relative thereto. The circumferential width of each tooth formed on the toothed disk is preferably larger than the circumferential width of each tooth formed on the first gear, and the outer diameter of the toothed disk can be larger than the outer diameter of the first gear. The first gear and the toothed disk mesh with a second gear such that as the second gear rotates, the toothed disk and the first gear also rotate. However, the toothed disk and the first gear rotate at different speeds because the difference in the number of teeth formed thereon. Because the teeth formed on the toothed disk have a larger circumferential thickness and a larger outer diameter than the teeth formed on the first gear, a tight meshing engagement with the second gear is provided. This tight meshing engagement, in combination with the frictional engagement of the toothed disk with the first gear, takes up backlash between the first gear and the second gear.
