Title: Brake light for road vehicle
Inventor: BAIRLEIN WILHELM ALEXANDER
IPC: B60Q1/44
Filed: 1997-03-29
Abstract: The action of the rear brake light of a vehicle is enhanced by an additional control which reacts to the release of the accelerator pedal. It operates the brake lights a split second before the brake pedal is pressed. The control system also operates the brake lights before the vehicle slows following release of the accelerator pedal. This gives the following driver an earlier indication of danger and contributes to a reduction of collisions.

Title: Method for establishing irradiation position in scanning electron microscopy
Inventor: KANOH EIJI
IPC: H01J37/256
Filed: 1997-09-12
Abstract: The method for setting an electron or laser beam on the surface of an object in order to detect foreign bodies uses an X-Y table (21) with a plate (51) bearing a very small projection (51a), approximately 2 mu  in height and diameter. This table can be moved relative to an external laser source (32) and a photodetector (33). In order to position the table accurately, it is first moved so that the beam falls on the projection. This position is then identified and used as a reference, as detected by the longitudinal and lateral reference coders (22a,22b). The position of foreign bodies on the surface of an object placed on the table is then more easily detected and identified.

Patent DE-19747562-A1 (DE)
Inventor: BOEHNKE GERD DIPL PHYS
IPC: H04R9/02
Filed: 1997-10-28
Abstract: The aim of the invention is to improve the propagation of magnetic fields by electrodynamic/-magnetic transducers, especially in telecommunications devices, in such a way that the static magnetic fields generated by the transducers are essentially screened and the dynamic magnetic fields are essentially emitted unhindered. To this end, a magnetic cover which is essentially impermeable to the static magnetic fields of an electrodynamic/-magnetic transducer is used at least in the sound delivery area of the transducer. The cover is penetrated by a number of openings whose dimensions are such that the cover maintains a predetermined resistance and rigidity when provided with the openings compared to its original resistance and rigidity, so that it is still easy to assemble mechanically, so that the openings allow through a predetermined sound pressure level which can be produced by the transducer, and so that the openings physically limit eddy currents on the cover caused by dynamic magnetic fields of the transducer, thus preventing them from reaching their full strength.

Patent DE-19810573-A1 (DE)
Inventor: SENN BRUNO
IPC: H05B41/00
Filed: 1998-03-11
Abstract: The control circuit for a light setting apparatus, to harden dental material by light polymerization using a hand-held light gun, controls the power supply with a preset nominal power rating. The cable (16) between the apparatus and the light gun is in the control circuit. The control suppresses the switching on of the apparatus (10), or generates a signal, when the nominal power has a voltage which breaches the control voltage bias (39) following a voltage drop at a field effect transistor (FET) (46) or a corresponding current. A voltage monitor (72) registers the terminal voltage of the lamp (24), and a current monitor (70) registers the lamp current. Their signals are passed to an evaluation circuit (60) by a control line (44) through the cable (16). The feeder station (12) has a control circuit (38) and especially a switch control, and controls the FET (46), linked by a control line (44) through the cable (16). The hand unit (14) has a calibrator (80) to calibrate the monitors (70, 72) and the evaluation circuit (60), especially as a digital/analog converter in the evaluation circuit (60). The evaluation circuit (60) is connected to a switch button (22) at the hand unit (14), especially as a key function to give an immediate start signal when the button (22) is pressed. The control circuit (38) at the feeder station (12) has a control characteristic curve which begins with a soft start value of the output voltage (54) for the lamp (24) through the cable (16), followed by a linear increase through a rising control voltage. The rate of increase from the control circuit (38) to the FET (46) is ≥ 1. The power control at the hand unit (14) takes into account the length of the cable (16) between the hand unit (14) and feeder station (12). The FET (46) delivers a controlled output voltage (54) to the cable (16). An auxiliary feed voltage (42) is fed through the cable (16) to the hand unit (14) for a blower (26), and also for other auxiliary units (66), independently of the controlled output voltage (54). The evaluation circuit (60) has an output connection for the blower (26), where the duration of the switched-on time for the blower (26) to cool the lamp (24) is determined from the total illumination time of the lamp, or its total uninterrupted lighting time. The calibrator (80) registers all the components of the hand unit (14) which are subject to tolerances, on the comparisons, and the calibration data are stored especially in an EEPROM. Each hand unit (14) is calibrated independently of the cable (16) length between it and the feeder station (12). The evaluation circuit (60) has a signaling unit (62) to indicate a lamp change, when the internal resistance of the lamp (24) is outside a given threshold value. The threshold value matches a value of the controlled output voltage (54). The value of the control voltage bias (39) is also the minimum voltage drop of the FET (46).

Patent DE-19830016-A1 (DE)
Title: Electronic over-current release operating method for power switch
Inventor: ETTE BERND
IPC: H02H1/04
Filed: 1998-06-26
Abstract: The method involves calculating at least one characteristic size for a curve shape of the current within each period in the over-current release. The characteristic size is compared with a preset threshold value specific to the connected load, and the switching off of the power switch is triggered only at the overstepping of the measured characteristic size above the preset threshold value.  A slope element of the current, calculated within each period as a ratio of a slope and an effective value of the current, is preferably evaluated as the characteristic size.

Title: Method of heat quantity measurement for heating circuits with flowing heating media
IPC: G01K17/10
Filed: 1998-07-14
Abstract: The method involves measuring the volume flow and temperature of the heating medium through the heating circuit with a volume flow transducer (10). There are temperature sensors (11,12) in the forward and return flow paths (5,6) and a computer. The computer forms a temperature difference and combines this with volume flow data. The two temperature sensors are first placed at a common measurement point in the circuit before being placed in the forward and return paths, enabling simultaneous detection of the forward temperature. The resulting data are stored for each sensor over a wide range of temperatures and later used in conjunction with the measurement data.
