Title: Test card for integrated circuits measuring low current levels
Inventor: SCHWINDT RANDY J
IPC: G01R31/02
Filed: 1996-11-26
Abstract: The test card for measurement of extremely low currents, to check integrated circuits and the like, is a dielectric card such as of glass/epoxy material, fitted with an opening. A number of scanning measurement units, such as ceramic platelets, are located round the opening edge so that their scanning components or needles pass below the opening in a pattern suitable for testing the component.

Each cable section on the card is coaxial, with an inner layer between the inner dielectric and the outer conductor to suppress the friction electrical effects.
Patent DE-19651709-A1 (DE)
Inventor: ALTVATER ULRICH
IPC: H04B1/713
Filed: 1996-12-12
Abstract: The invention describes a method for operating a network of secondary users (13) which uses a circuit of channels (f(K)) in a frequency spectrum (23) used by primary users (24, 25, 26) in the frequency jumping method for data transmission. A channel (f60) selected each time by the network of secondary users (13) is listened to before a possible data transmission and thus checked for whether primary users (24, 25, 26) are using this channel (f60) at a given time. Depending on the result of this examination, the network of secondary users (13) either transmits data via the selected channel (f60) or selects a new channel for examination and possible data transmission. In order to optimize data throughput, a circuit of the channels (f(K)) available for secondary users (13) is produced by removing, at least temporarily, a channel (f(K)) that is not only momentarily used by a primary user (24, 25, 26) from the circuit of channels.

Title: Simple but precise pressure injection moulding method producing cartridge complete with nozzle used to contain e.g. mastic
Inventor: BRUENING WERNER
IPC: B29C45/36
Filed: 1997-01-30
Abstract: Here is a novel method making a cartridge with attached nozzle. This has an annular shoulder (12) bordered by a cylindrical cartridge. The nozzle (14) projects from the annular shoulder, tapering to a tip. Melt is injected into the hollow mould containing a core. During the first phase of injection, the core is supported. This support is afforded by the centring region (41) at the transition between shoulder and nozzle. This region includes a number of conical centring bridges (40), against which the core rests. There is an after-injection phase. During this, the core or a part of it, is retracted. This allows those regions providing support, and therefore initially void of filling, to be completed. Also claimed is the corresponding equipment to make the nozzle cartridge, essentially as described.

Patent DE-19721902-A1 (DE)
Inventor: NICKELL STEPHAN
IPC: A61B5/00
Filed: 1997-05-26
Abstract: The invention relates to a method and a device for in vivo detection of the direction of Langer's lines in the skin. Light is irradiated as primary light into the skin at one precise point (7) identified through the epiderm (6), in such a way that it is transported in the skin (5) by dispersion or absorption, while part of said irradiated light comes out again as secondary light in the region surrounding the irradiation point. An amplitude-dependent feature of secondary light coming out again from the skin (5) around the irradiation point is measured so as to determine the preferential direction of the diffuse light transport in the skin (5) and, consequently, the orientation of Langer's lines thereof.

Patent DE-19729580-A1 (DE)
Title: Motor vehicle control
Inventor: SCHULMEISTER ULRICH
IPC: F02D41/02
Filed: 1997-07-10
Abstract: The control unit (21) is connected to receive input signals from e.g. a lambda sensor (13) and pressure sensor (19). The control unit contains a microprocessor with a read only memory containing a program to control the engine. The actual timing of the injection of fuel via an injection valve (8) into the combustion chamber (4) occurs according to a time grid assigned by the sequence of preset angles of rotation of a shaft in the engine (1). The smaller the grid, the smaller the angle of rotation so the more exact the actual time for the fuel injection.  When the engine has a higher revs and a greater load, the grid has wider angles. The control unit therefore has less time to process, however the time is increased by the wider angle and is thus compensated for. When the engine revs are lower, the control unit has more time, which is also compensated for by the smaller angle distances.

Title: Target detection method with radar system
Inventor: BODENMUELLER EDELTRAUD DIPL IN
IPC: G01S7/292
Filed: 1997-08-09
Abstract: The method involves selecting a measurement field of defined size, and dividing it into small fields containing a known number of radar cells with possible echo amplitudes. Small fields are marked with echo amplitudes exceeding the mean echo amplitude over the measurement field by a defined factor. All echo amplitudes from a marked field are fed directly to a target extractor which determines a first target frame. Echo amplitudes outside the frame are rotation corrected and fed to the extractor for target detection.
