Abstract: A method and circuit for distinguishing between a first voltage signal having a high amplitude and a second voltage signal having a low amplitude, the first and second voltage signals comprising respective AC components superimposed on a DC level. The DC level of the first and second voltage signals is blocked and the respective AC components of the first and second signals are attenuated by an attenuation factor which is voltage dependent and substantially frequency independent, so that the respective AC components of the first and second voltage signals after attenuation have similar amplitudes. The respective attenuated AC components of the first and second voltage signals are then processed so as to distinguish between the first and second voltage signals according to their respective frequencies.

The non-volatile memory comprises a write-protected area containing an original initialization and download operation program version, and an unprotected area containing an upgradable initialization and download operation program version. Upon initialization, the upgradable, or the original version, of the initialization and download operation program version is copied into a second memory and/or into a memory location. The embedded system is operated from the second memory and/or memory location, enabling the downloading of the new operating software and/or initialization program versions and programming the unprotected area with the downloaded versions.

Abstract: An electrically powered coolant pump particularly suited for an internal combustion engine has a pump housing having an elongate shape which encloses a pump wheel on the inlet side and subsequently downstream therefrom encloses an electric motor. An annular flow passage for the coolant is formed between the pump housing and the outside of the electric motor. The electric motor is encapsulated against the coolant, and the structural component of electric motor and pump wheel is retained in the axial range of the electric motor with at least one web in the pump housing through which connections for driving the electric motor are routed. The electric motor is cooled by the coolant flowing by, and may therefore be operated at very high rotational speeds, so that a small structural size and a low weight may be realized. Widely varying installation locations for the coolant pump are therefore possible.

A particularly advantageous-design of the embossing rollers (1a, 1b) provides foil webs which have knobs with a draped or folded type structure.

Abstract: A method of anticipating an access code such as a telephone number. A database of reference access codes is provided. As each character of a new access code is dialed, the database is searched for reference access codes that have the same leading digits. If one match is found, that matching reference access code is displayed to allow the user to call it without dialing new characters. If more than one match is found, the matching reference access codes are ranked according to a selection criterion. Preferably, the database includes an indication of the history of usage of the reference access codes and the selection criterion is based on the usage histories of the reference access codes, for example, according to their times of most recent usage, and also according to other criteria such as current day of the week. The highest ranking reference code is displayed. If the user completes dialing with no match found, then the newly dialed access code is included in the database.

Abstract: The invention relates to a die stamping method and to a device for performing the method. The problem of the invention is to reduce the production of waste during die stamping. This is brought about in that on supplying the foil web to the stamping station a sensor means monitors whether there is a defect therein. If a defect is detected, the foil web supply to the stamping station is controlled in such a way that the defect is conveyed through the stamping station between two stamping operations. Thus, the defect does not arrive in the stamping or printing area of the stamping station, so that no waste is produced.

During printing operation, the printing drums 25 and 26 are rotated with a rotational phase angle of 180 degrees relative to the press drum and, at termination of printing operation, the printing drums 25 and 26 are stopped at respective stationary rest positions which are out of ink stain zones of respective printing drums.

Abstract: In a hot pressing apparatus, a hot-plate pressing cylinder is provided at the center of a moving plate, and a substantially central part of each of the materials to be laminated between hot plates, which are pressed by a fixed plate and a moving plate, is pressed by a hot-plate pressing cylinder of the moving plate. Thus, a uniform pressure can be applied to the materials to be laminated, thereby preventing the occurrence of defects such as wrinkles and bubbles in the products.

Abstract: The invention relates to a high frequency board-to-board connector for interconnecting electronic sub-assemblies. The high frequency board-to-board connector includes a row of conductive pins received in an insulative housing for connecting with receptacles of a design. Two discrete electronic sub-assemblies, for example PCBs, can be mechanically and electrically connected without the need for a gender male connector on one PCB and a corresponding gender female connector on the other PCB. A plurality of follower arms spaced apart along the grounding plate facilitates contact with a ground plane in the design to form a ground path. The ground path reduces electromagnetic coupling between any pair of conductive pins and consequentially lowering cross-talk noise. Furthermore, inductive parasitics of the conductive pins is reduced, further facilitating high frequency operations.
