    摘要: An apparatus for producing a vacuum arc plasma source device using a low mass, compact inductive energy storage circuit powered by a low voltage DC supply acts as a vacuum arc plasma thruster. An inductor is charged through a switch, subsequently the switch is opened and a voltage spike of Ldi/dt is produced initiating plasma across a resistive path separating anode and cathode. The plasma is subsequently maintained by energy stored in the inductor. Plasma is produced from cathode material, which allows for any electrically conductive material to be used. A planar structure, a tubular structure, and a coaxial structure allow for consumption of cathode material feed and thereby long lifetime of the thruster for long durations of time.

    摘要: Hearing devices configured to fit within the bony portion of the ear canal and batteries that may be used with same. One such hearing device includes a hearing device core, defining a size and a shape, and including a battery and an acoustic assembly, with a microphone and a receiver with a sound port that is adjacent to a portion of the battery, and a flexible seal apparatus on the hearing device core. The size, shape and configuration of the hearing device core, and the flexibility of the seal, are such that the hearing device is positionable within the ear canal bony region with the entire microphone medial of the bony-cartilaginous junction.
