Abstract: A programmable logic controller checks each statement of an instruction list (IL) program to determine if any such statement or the order of statements violates one of a set of syntax rules which are stored in a memory in the controller. If a rule violation is found, an error indication is generated to signify that the particular IL program under test by the controller can not be accurately converted or translated into a relay ladder diagram. However, if no rule violation is found by the controller, then the controller accepts the IL program.

Abstract: The method of measurement serves to determine the sliding friction coefficient between flexible, flat sheets of material such as, for example, for paper test strips A and B. The two test strips A and B to be measured are mounted with their ends parallel to the pulling direction and their loose ends are fed in the opposite direction through a slit disposed transversely to the pulling direction and formed from a roller pair (8; 9). The oppositely situated test strips A and B are loaded with a loading  force FN determined by the roller pair (8; 9) and, optionally, by loading weights (11). The actual measurement is performed by moving the test strips A and B parallel to the pulling direction at constant speed in opposite directions through the roller slit (14), the frictional force of the test strips A and B which glide over one another being measured by means of a force transducer (5). <IMAGE>

Abstract: To protect an automatic friction clutch of a motor vehicle, it is proposed periodically to calculate data for the instantaneous friction power of the clutch (5) by means of a computing device (23) and to sum them in a plurality of time window memories likewise updated periodically. The time window memories have different time windows and accordingly store a spectrum of averages for the work of friction. The time window memories are each allocated a plurality of limiting values, the magnitude of which is additionally a function of the air temperature of a clutch bell (37) surrounding the clutch (5). A computing device (23) initiates graduated protective measures as a function of the temperature measured by means of a temperature sensor (35) and of the limiting values decisive for this temperature. For safety reasons, none of the protective measures prevents the clutch (5) from operating completely. As the thermal loading on the clutch (5) increases, all that occurs is that the comfort of the clutch is increasingly reduced, active measures which do impair comfort, such as, for example, oscillations of an actuator (19) of the clutch (5) resulting in grabbing of the clutch (5) being brought about when the maximum load limit is approached. <IMAGE>
Patent EP-0445887-A2 (EP)
Inventor: OWEN FRANK CHARLES GWYN
IPC: H04B1/04
Filed: 1991-03-04
Abstract: In some TDD communications systems such as DECT it has been proposed that in an idle period a primary (or base) station transmits some basic system and timing information as a normal idle beacon message once every frame and that paging messages to secondary stations (or portables) be sent once every 16 frames. In relatively long idle periods, for example at night, these frequent normal idle beacon messages are not required and represent a source of undesirable interference and a waste of power. In order to reduce this undesirable interference it is proposed that the primary station, subject to certain conditions being determined by the primary station, invites in-range secondary stations to participate in a low duty cycle link mode in which the primary station transmits paging messages as required and low duty link reassurance messages at relatively long intervals. In this mode the secondary stations are controlled to wake up at the required intervals. However, if the surrounding interference increases, the system reverts to the normal idle state.

Abstract: A superconducting variable phase shifter (10) providing improved performance in the microwave and millimeter wave frequency ranges. The superconducting variable phase shifter includes a transmission (18,20,22) line and an array of superconducting quantum interference devices (SQUID's) (14) connected in parallel with and distributed along the length of the transmission line. A DC control current IDC varies the inductance of the individual SQUID's and thereby the distributed inductance of the transmission line, thus controlling the propagation speed, or phase shift, of signals carried by the transmission line. The superconducting variable phase shifter provides a continuously variable time delay or phase shift over a wide signal bandwidth and over a wide range of frequencies, with an insertion loss of less than 1 dB. The phase shifter requires less than a milliwatt of power and, if one or more of the Josephson junctions (24) fails, the whole device remains operational, since the SQUID's are connected in parallel.

Abstract: An active sound reproducer (76, 78) receives an audio signal and setting signals (volume settings, filter coefficients)  via  a digital bus (75) for processing the audio signal. Normally, the setting signals are applied by a suitable ("compatible") control unit (74). If this unit is not present, this task is taken over by one sound reproducer operating as a "master". In a setup procedure it is determined which one of the sound reproducers operates as a master. Each sound reproducer is adapted to receive remote control signals and to transmit these signals to the master reproducer  via  the digital bus. This master reproducer then distributes the setting signals to the relevant sound reproducers  via  the digital bus. The control unit or the reproducer operating as a master may be located in another space.

Abstract: An analog baseband signal (32) modulates a reference frequency carrier signal (38) to provide a double sideband, suppressed-carrier DSB-SC signal. The DSC-SC signal is converted in a voltage-to-frequency converter (54) to a series of pulses, the repetition rate of which is proportional to the level of the DSB-SC signal. The output signal of the voltage-to-frequency converter is demodulated to produce a digitally formatted version (62) of the baseband signal. A notch filter to reflect an undesired signal is provided as a feedback path from the output voltage-to-frequency converter (54) to a negative input of a summer (48) in the input line of the DSB-SC signal. The feedback path converts the frequency signal from converter (54) to a cancellation signal having the format of the undesired signal.
