Title: Optical tomography of tissue structure and blood perfusion
Inventor: BLAZEK VLADIMIER PROF DR ING
IPC: G01N23/04
Filed: 1997-01-10
Abstract: Device comprises a CHIRP enabled coherent laser light source, with the CHIRP process running in two multiplexed modes, time and frequency. Through the transit time evaluation of the "chirped" photons, a purely electronic depth scan of the object can be rapidly carried out. Using the frequency phase, photons marked using the Doppler effect, the device is used for determination of blood perfusion. Lateral scanning of the object is carried out with multiple point light sources linked by time delaying fibre optic cable and with electronic separation. Structural information carried by back scattered photons is used to produce a tomographic, panoramic image.

Patent DE-19725522-A1 (DE)
Inventor: BERNAUER CHRISTOF
IPC: H02P6/08
Filed: 1997-06-17
Abstract: The invention relates to an electronically commutated motor, comprising a stator, said stator supporting several winding phases, with several magnetic poles and grooves, and a rotor. A defined position of the rotor and the stator in relation to each other can be identified by means of a position-detection device. The rotational speed and power output of the motor are easy to influence since the magnetic poles have areas which have air gaps with the rotor at different heights and since the times at which the current is applied consecutively to the phase windings and/or the duration of the phase winding can be modified in relation to the positioning of the rotor and stator.

Title: Internal combustion engine combustion state determining device
Inventor: TAKAHASHI YASUHIRO
IPC: G01M15/04
Filed: 1997-08-06
Abstract: The device has a coil (4) which generates a high voltage for ignition. A spark plug (8) ignites an air/fuel mixture in a cylinder of the engine by discharging the high voltage. An ion current detector detects an ion current signal corresponding to the number of ions that are generated in the cylinder directly after the combustion of the air/fuel mixture. A pulse-generating circuit (20) executes wave-shaping of the ion current signal into an ion pulse signal. A crankshaft angle sensor generates a signal indicating a first and second reference crankshaft angles (75 and 5 deg  before top dead centre). An electronic control unit generates an ignition signal to excite or de-excite the coil according to the crankshaft angle and which determines the combustion state in the plugs according to the ion pulse signal. The electronic control unit has a flank detector for the end flank of an ion pulse which is contained in the pulse signal in the detection zone extending from the second to the first reference angle. A level detector detects the level of the pulse signal at the first reference angle. It also has a device to determine the combustion state of the engine according to the outputs received from the previous two devices.
