Title: Device for automatically waking a sleeping individual after a dream
Inventor: KARRAS DETLEF
IPC: A61M21/00
Filed: 1981-01-21
Abstract: For psychotherapeutic purposes and for research into unconscious emotional processes it is important and necessary to remember dreams. The best method of remembering a dream is to be woken immediately after a dream and to record its contents immediately. The invention is based on the object of permitting automatic waking after a dream. For this, the rapid eye movement phase (REM phase) which occurs during dreaming is recorded by electronic means. The drawing shows that the waking process is achieved in that at least two electrodes (1) are fastened in the eye region of the sleeping individual and are attached via supply lines (2) to a handy, electronic control device (3) in which the voltages caused by the eye movements are intensified and analysed in such a way that they lead to triggering of a waking signal when a value exceeds a threshold value and then falls below this, and when a further voltage increase is missing during a predetermined time interval.

Title: Circuit arrangement for determining the characteristic features of liquids and/or gases, in particular the haemoglobin concentration of the blood
Inventor: CSEREY LASZLO
IPC: G01J1/16
Filed: 1981-02-25
Abstract: Built into the circuit arrangement is a photometer which has two light paths and contains a reference light sensor (7) and a character converter (9) whose character ratio is determined by programmable, continuous or periodic testing, as a result of which it is ensured that the entire measurement channel is monitored. The character processing is performed by series expansion or by taking logarithms to carry out break-point interpolation, or by an averaging process for which adjustable, error-determining subcircuits (11) are built in. The great advantage of the circuit arrangement consists in that the instability of conventional photometers is eliminated and a higher measurement accuracy can be ensured. In addition, the invention ensures the possibility of testing and therefore - since self-monitoring is carried out - the supply of reliable measured data. <IMAGE>
