Title: Accelerometer producing digital output - uses vibrator with acceleration dependent resonant frequency produced by non-linear element, followed by frequency conversion
Inventor: EUER HARTMUT
IPC: G01P15/10
Filed: 1979-04-20
Abstract: An acceleratometer is designed to produce digital output signals at relatively lower cost than conventional arrangements which use analogue-to-digital converters. The sensor consists of an oscillating element arranged in a self-excitation circuit with an oscillation stimulator and an oscillation detector connected to it via a feedback circuit. The oscillator or vibrator has an oscillatory mass arranged to vary the resonant frequency of the oscillating element by virtue of its effective point variation under acceleration. The oscillation detector drives a frequency-code converter, producing a digital output signal corresp. to the instantaneous frequency of oscillation detected. The vibrating element has a non-linear spring characteristic for acceleration dependent resonant frequency variation. This may be augmented by a damping element.

Title: Anti-intrusion security device for surfaces, e.g. shop windows - has multiple reflective surfaces with light emitter and receiver to form optical protective curtain
Inventor: KREUTTNER ALBERT DIPL ING
IPC: G08B13/184
Filed: 1980-04-22
Abstract: The surface to be protected e.g. shop window (1), has a reflective border situated at the upper and lower part of the internal frame (2,3), and in the upper corner of the frame, a light source (4) is fixed, and in the opposite upper corner, a receiver (5). The light source (4) can be a Galluim-arsenide diode or similar, and the light emitted by it reaches the receiver (5) after being reflected a number of times back and forth by the reflective borders (2,3). This forms a light curtain which changes in intensity at the receiver (5) if an object or person enters the field of coverage. The mirror-like reflective borders (2,3) are made up of a number of parallel running 'V'-shaped channels, each one forming a 90 degree angle mirror, made of plastic, and numbering about twenty to thirty channels per border. This enables a cheaply produced security device for windows to be manufactured by the injection moulding process.
