IPC: G01N21/93
Filed: 1995-03-15
Abstract: The sheet of glass to be examined (1) is placed horizontally in a support frame (2) and is illuminated uniformly with white light from a source (4). The light falling on the glass plate is reflected on to a screen (6). The image appearing on this screen is captured by one or several colour video cameras (12-15). For each primary colour, and for each point on the image the luminance is determined, and the relative colour reaction for each colour is calculated by dividing the luminance value for one colour by the sum of the luminance values for that point. These relative colour fractions are then compared with predetermined reference values.

Title: Turbocharged engine
Inventor: HOERSTER CHRISTOPH DR
IPC: F02D41/00
Filed: 1996-06-27
Abstract: The engine has two or more exhaust pipes containing turbochargers. A common unit detects the air delivered. A setting device for the air acts on all the turbochargers. The fault detector monitors the charge-air pressure downstream of the turbochargers and initiates protective measures when a threshold value is exceeded. This can consist of a single pressure-sensor for all the air from the turbochargers, and the threshold value can be between 1.05 and 1.2 times the desired charge-air pressure at the particular operating condition. The protective action can consist in stopping firing of individual cylinders in a multi-cylinder engine.

Title: Automatic dialling method especially for automatic generation of call loop of established telephone number
Inventor: KIM JONG-KWANG
IPC: H04M1/72502
Filed: 1996-07-08
Abstract: The method uses a VOX switch to detect a state without speech and a tone detector detects an engaged tone to provide information when a call has ended. A memory stores an external telephone number and a loud speaker telephone carries out a telephone call via an external microphone and a loud speaker. The mobile station has an on/off switch to determine an open state and a closed state of a switch. It also has a call key to forward a call. The method involves receiving a key input signal corresponding to an external telephone number for automatic calling of a remote person to register the input signal in the memory. An automatic call mode is established to automatically call the remote person and dial the registered telephone number after receiving a call command to generate the call. The call is ended when the end of the call is detected and the automatic calling mode is converted into a standby condition.

Title: Radar signal processing method, especially for pulse Doppler vehicle distance radar
Inventor: ELTERICH ANDREAS DIPL ING
IPC: G01S13/931
Filed: 1996-09-12
Abstract: The measuring process is divided into several successive intervals and each interval into cells and the individual cells defined by the parameters characterising the radar signals to be detected. The method employed is the cell averaging process and average values for interference power are derived from the measurements on individual cells. To prepare for constant false alarms, the process is enhanced by means of ordered statistics, the OS-CFAR method. The interference has to be adapted to the target and an estimate of the interference is selected as a basis for the calculations.

Patent DE-19643179-A1 (DE)
Title: Stability control for motor vehicle
Inventor: MONZAKI SHIROU
IPC: B60T8/172
Filed: 1996-10-18
Abstract: The vehicle is fitted with sensors to determine instability eg. drift during cornering. The control selectively applies the front and rear brakes to correct the drift. The control system has an added mode of control to prevent hunting of the braking system which, when applied near the resonant frequencies of the vehicle dynamic state, could cause additional instability. The control system limits the maximum rate at which the brakes are applied and varies this rate w.r.t. the vehicle dynamic state ie. the steering setting and the vehicle speed etc. The control has different threshold values when the brakes are not applied, which are reduced as soon as braking begins.

Title: High power solid state laser apparatus for material processing e.g. work piece production
Inventor: HOLLEMAN GERALD W
IPC: H01S3/106
Filed: 1997-01-09
Abstract: The apparatus has a laser resonator formed with two reflectors (10,12) with at least one solid state amplifier (18), e.g. a zig-zag amplifier, within the resonator. A pumping control circuit (22) controls a series of pump diodes (20) adjacent to the amplifier, the circuit turning the pump diodes on and off. Also within the resonator path is an acousto-optical modulator (14) and a polariser (16).  A radio frequency source is coupled to the modulator to produce a sequence of laser output pulses of constant pulse width and pulse amplitude during each pump macro impulse to control the energy output from the laser. The pump diode control circuit determines the length and frequency of pumped macro impulses to control the number and total energy of emitted laser pulses without the back-coupling of the laser radiation to control the modulator. The duration of the output pulses last between 100 nanoseconds to 300 nanoseconds, interspersed by the natural relaxation frequency of the laser.
