Title: Cortical hearing aid - had harmonic generator connected between AF pre-amplifier and AF amplifier
Inventor: SCHAFER CURTISS REINECKE
IPC: A61F11/04
Filed: 1977-08-10
Abstract: "Hearing" without involving the ear is realized by electrical conduction of the sound-representing signals on a carrier optimally in the frequency range of 15-60 kHz, from an electrode held against a person's head to the auditory cortex and possibly to the auditory nerve. This is called a "cortical hearing aid". The ability of the person to recognize sounds with a cortical hearing aid is enhanced by introduction of significant distortion of the audio signals, especially low-order harmonics of the audio frequencies. The distortion acts as a substitute for distortion ordinarily occurring in the ear but disregarded in the hearing process.

Title: Pulse generator using Wiegand wire - assigned to induction coil and responsive only to one direction of rotation of magnetised stator
Inventor: HAULER PETER DIPL ING
IPC: G01P13/04
Filed: 1978-04-20
Abstract: A pulse generator is based on the relative displacement of a first part, having sections of alternate magnetic polarity i.e. a rotor, on a second part fitted with a Wiegand wire and a receiver coil assigned to the wire. A simple, detection of direction of movement of the rotor is realised since pulses are introduced in the receiver coil only during relative movement of the sections of alternate magnetic polarity in one direction relative to the Wiegand wire. No pulses are induced during movement of the rotor in the opposite direction. Thus, the Wiegand effect wire axis is inclined at an acute angle relative to the direction of movement of the alternate magnetic polarity sections.
