  • Publication number: 20220295169
    Abstract: A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.

  • Patent number: 4202004
    Abstract: A crystal of a semiconductor material has an electrically conducting loom assembly embedded therein, whereby the crystal and loom assembly define a unit which converts light or other electromagnetic radiation into an electrical current for flow to an external electrical circuit. The loom assembly has a plurality of electrodes coated with another semiconductor material so that the semiconductor materials define a plurality of n-p junctions within the crystal. Radiation absorbed by the crystal will liberate electrons which will flow across the junctions and along electrical paths formed in the loom assembly to conductor means which can be connected to an external electrical circuit. The loom assembly comprises a plurality of very small loom units comprised of pairs of spaced electrodes, one of the electrodes of each loom unit having a coating of a semiconductor material in contact with the semiconductor material of the crystal.
