Abstract: A TDMA network (100) for reader-transponder communications including a receiver (132) having an antenna (116) for receiving and transforming radiated energy to a first RF signal and a detector (106) for demodulating and converting the first RF signal to a digital signal. A protocol logic device (110) is provided for decoding the digital signal and for executing a protocol. The protocol comprises a plurality of randomly selected time slots (152) to gain admission to the TDMA network (100) and a plurality of assigned time slots (154) to transmit messages (164) during the reader-transponder communications. In a transponder (114) implementation, an oscillator (108) is provided for converting protocol formatted digital signals from the logic device (110) to a second RF signal. Thereafter, the antenna (116) transforms the second RF signal to radiated energy and transmits the radiated energy. In a preferred embodiment, the TDMA network (100) includes a transmit/receive switch (130) for directing the first and second RF signals along the receive and transmit paths, respectively. A digital memory (138) which communicates with the protocol logic device (110) is provided for storing data unique to a transponder (114). The protocol also includes a reader control message time slot (156) for interrogating the transponder (114) and an acknowledgment time slot (158) for indicating the reception of a message (164).

Abstract: A liquid crystal display device is constituted by a pair of electrode plates each having a plurality of elongated electrodes, and a layer of ferroelectric liquid crystal disposed between the electrode plates so as to form a pixel at each intersection of elongated electrodes disposed respectively on the pair of electrodes plates. At least one electrode plate is provided with an unevenness at each pixel so as to form a cell thickness gradient (α₁α₂), within each pixel, and at least one electrode plate is provided with at least three types of color filters each corresponding to a pixel. Further, each color filter and/or each pixel (R,G,B) is set to have an area and/or a shape varying depending on a local cell thickness so that light quantities or sensible light quantities transmitted through the respective filters and the liquid crystal layer are identical to each other regardless of the type of color filter. A similar pixel pattern deformation is effective for providing a linear T (transmittance) - log V (voltage) characteristic. Color pixels pattern deformation may preferably be effected in a complementary manner with respect to different colors.

Abstract: When the processing circuitry of a signal processor can handle data at a faster rate than the rate of arrival of signal units to be processed, the processor is able to execute a cycle of microcodes for each arriving signal unit. To generate the cycle, the signal processor contains base address reproducing means, for in each cycle reproducing a standard sequence of successive base addresses BA(i) (i=1..N). The base address reproducing means feed microcode selecting means for selecting, in step with each base address and under control of signal data received from the processing circuitry, an associated microcode address MA(i) from a repertory of microcode addresses indicated by the base address BA(i). Selection is implemented by adding each base address BA(i) to an associated index IA(i), determined in dependence on signal data received from the processing circuitry. Usually, the indices IA(i) require fewer bits than the base addresses BA(i); the indices are determined in codependence of the base address, or of a signal identifying a class to which the base address belongs. The signal data is collected from the processing circuitry via a shift register.

Abstract: By reacting cyanuric halides with organopolysiloxanes containing primary amino groups in substituents, organopolysiloxanes can be obtained in which two polysiloxane chains are linked via a divalent radical. The divalent radical contains 1,3,5-triazine rings to which a halogen atom is also bonded. The organopolysiloxanes obtained in this way are suitable for softening fibre materials. In particular, textile fabrics containing cellulose fibres can thus be provided with a soft hand (handle), the permanency of the finishing effects during washing processes being very good.

Abstract: The invention relates to an optical scanning arrangement for identifying a code 11 composed of successive light and dark zones forming in each case a module 16, 17, 18, 19, 20, 21, 22 consisting of an upwardly limited integral multiple of basic running lengths Bl to a module width M, in which code a predetermined number of successive modules 16, 17, 18, 19, 20, 21 and basic running lengths Bl form one character 25. The scanning device guides, by means of a light transmitter 14, a light spot 13, whose extension is smaller than the basic running length Bl, but is at a maximum only slightly larger than the basic running length Bl of the code 11, periodically successively over the modules 16, 17, 18, 19, 20, 21, 22. By means of its light receiver 15, the light scattered back from the region, of the code 11, encountered by the light spot 13 is received, and a corresponding electric signal is output at the output 24. By means of differentiation and rectification, a series of individual pulses 41 is formed. Connected to the light receiver 15 is a differential stage 26 with rectification and a counting stage 27 for the clock pulses generated by a clock generator 28 between in each case two predetermined levels of the edges of successive individual pulses 41. The individual counting results are applied to a memory 29 and stored there. Subsequently, a two-module selection stage 30 records in each case the measured width M' of two successive modules in units of the basic running length Bl. A correction stage 31 corrects each module width in the direction of the actual module width M in accordance with correction values stored there previously for each module width pair. For each measured module width M', a corrected module width signal is output.

Abstract: High melting temperature Pb/Sn 95/5 solder balls (18) are connected to copper pads on the bottom of a ceramic chip carrier substrate (10) by low melting temperature eutectic Pb/Sn solder. The connection is made by quick reflow to prevent dissolving Pb into the eutectic solder and raising its melting temperature. Then the module is placed on a fiberglass-epoxy circuit board with the solder balls on eutectic Pb/Sn solder bumps on copper pads of the board. The structure is reflowed to simultaneously melt the solder on both sides of the balls to allow each ball to center between the carrier pad and circuit board pad to form a more symmetric joint. This process results in structure that are more reliable under high temperature cycling. Also, to further improve reliability, the balls are made as large as the I/O spacing allows without bridging beam on balls; the two pads are about the same size with more solder on the smaller pad; the pads are at least 75% of the ball diameter; and the eutectic joints are made as large as possible without bridging between pads. For reliability at even higher temperature cycles or larger substrate sizes columns are used instead of balls.
