Title: Wet nappy monitoring system - uses electronic or battery operated device to signal wetness of children or incontinent adults
Inventor: BENKERT LEONHARD
IPC: A61F13/42
Filed: 1977-01-21
Abstract: The electronically controlled alarm, both optical and acoustic, signalling that a baby's nappy or pants have been soiled, can be applied to washable and throw away nappies or pants. It is useful in hospitals and nurseries, prevents a child from developing nappy rash from not being changed when needed and is time saving for staffs as the child does not have to be removed fron the nappy for examination when the nappy might still be dry. The alarm nappy is connected to a 2 volt battery, a mains connector or transformer by a plug top that lights up as the humidity increases. The system can be used in hospitals for incontinent adult patients.

Title: Record player pick=up return monitor - uses changeover device synchronised with motor to supply parallel signals to equaliser
Inventor: SCHROEDER ERNST DIPL ING
IPC: G11B21/04
Filed: 1979-02-05
Abstract: The record player uses a spiral groove to return the pickup arm at the finish of the record. A groove generates a sound signal at the loudspeaker, and is continued with a monitoring system to indicate if the groove is faulty. This prevents the pick-up arm from repeating its movements endlessly. Signals from the pick-up are passed to a switching device which operates at a frequency controlled by the motor, so that the switch is reversed for each rotation of the motor spindle. The signal are thus alternately diverted along parallel paths to two storage devices, with their outputs connected to an equaliser. When a difference signal is received, the equaliser operates the sound monitor.
