Title: Emergency mode circuit arrangement for communication terminals
Inventor: METZGER UWE
IPC: H04Q11/04
Filed: 1997-07-10
Abstract: The circuit arrangement includes a network termination (NT) to which terminals (TE) are connected directly or via an interposed telecommunication unit when in normal mode. A polarity of the supply voltage determined to the normal mode is supplied to the terminals in the normal mode. A power supply with an inverse polarity is supplied to the connection line (13) at the terminal, in the emergency mode when the local supply in the network termination or in the telecommunication terminal fails. The circuit arrangement consists of an additional circuit (36) which is connected in series to a terminal.  The polarity of the supply voltage for the norm mode is provided at the output of the additional circuit independent on the polarity of the supply voltage at the input of the additional circuit. The additional circuit includes an inductive operating current decoupler and current coupler for supplying the terminal with voltage. The current decoupler and current coupler are set up symmetrically.

Patent DE-19735149-A1 (DE)
Title: Application of coating to surface
Inventor: ELVIDGE DAVID RICHARD
IPC: B05C11/02
Filed: 1997-08-13
Abstract: The coating is discharged at a coating chamber which opens towards the surface and the surface is moved relative to the chamber. The amount of coating is dosed in a dosing gap (28) formed between the surface and dosing device. The dosing device can swing constantly in the rolling gap in order to reduce the amount of coating which the dosing device passes with the surface while the surface leaves the chamber. The vibration or swinging of the dosing device reduces the thickness of the film passing through the rolling gap for a predetermined pressure on the dosing rolling gap.

Patent DE-19807066-A1 (DE)
Inventor: MESSERSCHMID ERNST
IPC: B60R25/34
Filed: 1998-02-20
Abstract: Electronic anti-theft devices can be circumvented by exchanging or bridging critical components in a shielded manner. The present new invention avoids this by making the protection a functional part of the object to be protected. The security device, for example in a motor vehicle, is activated by irreversibly deactivating and/or deleting at least one of the components (5, 6, 7, 8) and/or information within at least one of these components (5, 6, 7, 8) essential for running the vehicle. In this way even the removal or bridging of the component concerned has no effect since the acquisition of a functional replacement part becomes unavoidable. The components can be housed, for example, in the engine electronics centre (6), the steering wheel lock (7), the door lock (8) and/or the key (5). By miniaturizing the receiver any electronic device can be protected, including mobile telephones, (Euro)cheque and cash cards, credit cards, telephone cards, keys for electronic locking devices, mobile electronic devices such as cassette decks, CD players, watches, computers, etc.

Patent DE-19825263-A1 (DE)
Title: Period counting circuit
Inventor: ISODA KAZUNARI
IPC: G01R23/10
Filed: 1998-06-05
Abstract: The circuit has a timer (203), which receives a clocking signal (T11) and performs a counting operation. A detector circuit (209) receives an input signal and detects at least the leading edge or the trailing edge of an input signal and initiates a detection signal. A holding resistor (204) is connected to both the detector circuit and the timer to hold one of the current values which has been counted by the timer. The detection signal acts as the trigger signal for the hold signal. A control circuit, which has a preset critical frequency, is connected between the detector circuit and the holding resistor, to compare the frequency of the detection signal with the preset critical frequency. If the detection signal frequency is greater than the critical frequency, the control circuit isolates the holding resistor from the detector circuit and a frequency measurement operation is discontinued. If the opposite is true, the control circuit connects the two and the holding resistor receives the detection signal as the hold trigger circuit. The timer simultaneously receives a cancellation signal for the values counted, resetting the values to an initial value and the counting operation recommences.
