Patent DE-19549297-A1 (DE)
Inventor: STIELAU GUENTER
IPC: A61B3/113
Filed: 1995-12-22
Abstract: The invention relates to a bio-feedback process for affecting the human psyche and a device for implementing it. According to the invention, eye movements, physiological parameters of eye muscles and/or nose root (22) muscles of a person are measured by sensors (1a, 1b) and the measurements transmitted to an evaluation system (2), which, by means of the measurements made in the immediate vicinity of the eyes and information stored in the evaluation system (2), assesses the psychological condition of the person. Depending on the data measured, the person is then stimulated by a stimulation system (3) with relaxing or tensing stimuli. It is thus possible to relax or stimulate a person's psyche in a targeted manner, whereby the person's psychological condition can be easily and accurately measured in the immediate vicinity of the eyes.

Patent DE-19609234-A1 (DE)
Inventor: KOOPS HANS W P DR
IPC: H01J17/44
Filed: 1996-03-09
Abstract: In known electronic tube systems the upper limit frequency and noise characteristics are limited by the known methods of producing miniaturised multiple electrode tubes, i.e. diodes, triode tubes and multi-electrode tubes. The tube systems disclosed here comprise one or more field-emission or field-ionisation cathodes connected in parallel for electrons or ions, a grid electrode with one or more annular apertures, and one or more anodes. All electrodes are formed consecutively or simultaneously, using corpuscular radiation lithography with indexed deposition, on a planar conducting strip structure which delivers the voltages. The electrode spacing is made sufficiently small to ensure that on average only a mean free path length of the molecules at normal pressure can pass between the emitters and the anode. The range of possible uses of the invention is very wide but relates in particular to high-frequency technology.

Patent DE-19633338-A1 (DE)
Title: Circuit for controlling threshold switch of railway vehicle wheel detector
Inventor: SCHMIDT HARALD DIPL ING
IPC: H03K5/08
Filed: 1996-08-07
Abstract: The circuit contains an oscillator inductively damped by passing wheels or a transmitter/receiver whose coupling is varied by passing wheels. A threshold switch compares the oscillator or receiver voltage with a reference voltage and responds to the voltage exceeding or falling below the reference, taking hysteresis into account, whereby the reference voltage is cyclically varied using clock pulses between values corresp. to sensor voltages with the sensor unaffected by wheels and with the sensor removed from the rails.  Each clock pulse reads in the current binary state of the threshold switch's output signal into a state memory with its leading edge. The non-affected state of the wheel sensor sets a timing element (T5) for operating a switch (S5) coincident with the trailing edge of the clock pulse. The switch sets the reference voltage input (+) of the threshold switch (SW) to a potential below the threshold switch's switch-on voltage.
