Patent EP-0289401-A2 (EP)
Inventor: SCHROEDER GENE F
IPC: H04J1/05
Filed: 1988-04-21
Abstract: The frequency division multiplexed input signal is sampled in an analog-to-digital converter. The samples are translated by mixing with base band frequency signals to yield real and imaginary values corresponding to phase information in the original modulation signals. After transla­tion, the translated samples are filtered in real and imaginary digital filters. After filtering, the original modulation information is recovered by analysis of the position of vectors in the complex plane represented by the real and imaginary values. In the preferred embodiment, a successive approxi­mation technique is used to determine the angle of the vectors to the real axis. Low pass output filtering may be employed after recovery of the modulation signal for improvements in signal to noise ratio. 
     In the preferred embodiment, the translation is performed by multiplying the input samples by digital values corresponding to sine and cosine values of local oscillator signals at base band frequencies. Preselect filtering may be employed prior to translation to decimate the input samples where possible to reduce subsequent processing requirements. 
     In the preferred embodiment, the unit is operated in a first initialization mode in which a microprocessor supplies appropriate filter coeffi­cients corresponding to the frequencies of the   channels to be demodulated. Thereafter, the microprocessor does not directly control supply of samples or coefficients to the filters for evalua­tion. Very high data rates are thus made possible.

Abstract: Method for addressing the processor units of a device for monitoring and/or controlling, in which processor units equipped with addresses can exchange information items. An automatic addressing of the processors unit is made possible by the fact that the processor units are provided with individual addresses in an addressing phase and, in a subsequent identification phase, send information items to an addressing device which provide the possibility of determining the arrangement of the processor units in the message transmission network. The method can be advantageously used in devices for monitoring systems in telecommunication engineering. <IMAGE>

Abstract: A safety device for preventing oxyhydrogen explosions is indicated, wherein the explosive gas mixture containing hydrogen and oxygen is passed along a surface suitable for initiating a controlled hydrogen oxidation. To achieve high conversions for the hydrogen oxidation in a small space, a heater element (4) which can be heated to the ignition temperature of the gas mixture is fixed inside a chamber (8) with porous chamber walls (2) through which the gas mixture can enter the chamber, see Figure 1. On the heater element, the oxidation of the hydrogen is initiated. The chamber walls (2) are here held at a temperature which is below the ignition temperature of the gas mixture in the surroundings of the chamber (2). Sintered material or porous ceramics are suitable for forming the porous chamber walls (2). A wire mesh or wire netting can also be used. <IMAGE>

Abstract: In the reference-position detection method and ap­paratus for detecting a reference position of a scale, first and second patterns are disposed on the scale so that respective detection timings shift inversely to each other in response to a deviation in attitude of the scale. The first and second patterns are detected with timings dif­ferent from each other by corresponding first and second sensors, and the reference position of the scale is deter­mined according to outputs of respective sensors. Hence, even if the attitude of the scale changes from a predeter­mined attitude due to an inclination of the scale or a deviation in position of the scale, it is possible to ex­actly detect the reference position of the scale. Accord­ingly, it becomes also possible to increase the performance of a displacement measuring apparatus.

Abstract: The surveillance device has an ultrasonic transmitter and an ultrasonic receiver for generating and detecting the sound waves occurring in the surveillance space, said sound waves being detected by an evaluator and, if appropriate, reported in an alarm. In order to obtain a particularly reliable and sensitive device, it is proposed that the transmitter repeatedly radiates a constantly reproducible transmission pulse of defined transmission duration into the surveillance space and the ultrasonic receiver detects the interference field for a measurement time which is exactly matched thereto, said interference field resulting both from the transmission pulses and from the reflection signals in the surveillance space. The time/measured value profile occurring during the measuring time is stored by an evaluator and compared with a profile which has occurred with a preceding transmission pulse. If the detected deviation lies outside a specific tolerance range, the alarm is activated. <IMAGE>

The invention also provides prosthetic devices which incorporate amniotic cells, and compositions for cosmetic use based upon amniotic cells or cell extracts. A further development uses amniotic cells in the form of a semi-permeable membrane, or coated onto, for example, microspheres; these structures act as filtration devices for the removal of toxic materials from, for example, blood or urine.

Abstract: A very slim and generally compact card reader for use with a so-called "smart card", i.e. having an integrated circuit connected to external contact pads to enable stored information to be read. A carriage (3) is slidably mounted in a chassis (2) and an abutment (4) supports and guides the card as it is inserted into the reader. Card reading contacts (13a) are supported by a plinth (13b) which is spaced from the card (1) when the carriage is in an initial card receiving position (see Figure 4a). Insertion of a card into the reader causes the carriage to slide along a lazy Z-shaped path (8) generally in the direction of card insertion towards a final card reading position (see Figure 4b) and the carriage thus presses the card against the abutment (4) causing the card to bend so that the contact pads are urged into engagement with the contacts on the plinth. Deflectable fingers (11,21) on the carriage or the chassis grip the card and help to maintain both the card and the carriage in the card reading position.

Abstract: In a proximity-reading coded-tag system, a coded tag (10) responds to a high-frequency interrogation signal by providing a binary signal of a predetermined low frequency and bearing a code that is unique to said tag; and by transmitting a high-frequency response signal of a given high frequency, with the response signal being modulated with the uniquely coded low-frequency binary signal; and a coded-tag reader (12, 12a) receives and demodulates the high-frequency response signal to detect the uniquely coded low-frequency binary signal. The modulator (24) of the coded tag modulates the response signal by shifting the center frequency of the response signal during each pulse of the low-frequency uniquely coded binary signal to thereby vary the amplitude at the given high frequency in the response signal in accordance with said unique binary code and at the rate of the predetermined low frequency; and the demodulator (36, 37) of the coded-tag reader is tuned to the predetermined low frequency of the coded binary signal for detecting the unique binary signal code in accordance with amplitude or phase variations at the given high frequency in the received high-frequency response signal caused by the frequency shifting.

Abstract: A two-dimensional input/output system (300) for a massively parallel SIMD computer system (100) providing an interface for the two-way transfer of data between a host computer (200) and the SIMD computer. A plurality of buffers (330) equal in number, and distributed with the individual processing elements (120) of the SIMD computer are used to provide a temporary storage area which allows data in different formats to be mapped in a format suitable for transfer to the host computer or for transfer to the SIMD processing elements. The temporary storage is controlled in such a way as to transfer entire blocks of data in a single SIMD system clock cycle thereby achieving an input/output data rate of N bits/cycle for a SIMD computer consisting of N processors. The system is capable of handling irregular as well as regular data structures. The system also emphasizes a distributed approach in having the input/output system divided into N pieces and distributed to each processor to reduce the wiring complexity while maintaining the I/O rate.
