Abstract: For the automatic choice of a hearing program, a hearing aid (1) detects whether it is located in the immediate vicinity of an external transmitter (10, 10?). The transmitter (10, 10?) generates a transmitter-specific signal so that an assignment of different transmitters can be made. In addition, in the case of the hearing aid (1), the current time of day and the day of the week can also influence the choice of the active hearing program.

Abstract: A printed circuit board configuration with a multipole plug-in connector has plug pins fixed parallel to the board layer on respective signal conductor tracks. The signal conductor tracks are configured essentially parallel and alternately side-to-side with ground conductor tracks. Furthermore, a ground shielding surface is provided on an adjacent board layer.

Abstract: For the automatic choice of a hearing program, a hearing aid (1) detects whether it is located in the immediate vicinity of an external transmitter (10, 10′). The transmitter (10, 10′) generates a transmitter-specific signal so that an assignment of different transmitters can be made. In addition, in the case of the hearing aid (1), the current time of day and the day of the week can also influence the choice of the active hearing program.

Abstract: In a serial, bidirectional data transmission method for communication between a programming device and a service device which is to be programmed, such as a hearing device, data are transmitted from the programming device and clock pulses are transmitted to the service device for individual adjustment of the application-specific data of the service device. Using a single signaling line, clock pulses that are variably formed for data transmission, are applied at the signaling line, and the digital information is recovered at the service device side by means of clock pulse variation and is subsequently processed with the transmitted clock pulse. Clock pulsewidth variation is performed as the clock pulse variation.

Abstract: An interface for serial data transmission between a hearing aid and a control device has a first data terminal for bi-directional data transmission to and from the hearing aid, a second data terminal for receiving a data format containing a start bit from the control device, and a third data terminal for data to be received by the control device, plus at least one coupler for data transmission from the second terminal to the first data terminal and at least one coupler for data transmission from the first data terminal to the third data terminal. The two couplers have an interactive (shared) connection which is normally placed at a first logic level, but which can be modified to a second logic level by signals either from the control device or from the hearing aid. The logic level at which the interactive connection is set determines which path data will be transmitted between respective terminals.
