Patent EP-0454345-A2 (EP)
Inventor: ARROYO CANDIDO JOHN
IPC: H02G3/30
Filed: 1991-04-16
Abstract: An undercarpet cable (40) includes a plurality of longitudinally extending interlocking segments (42-42). The segments are designed each to have an optical fiber (33) housed therein or when interlocked in an assembly to provide a longitudinally extending cavity for receiving an optical fiber. The assembly of segments is capable of being routed along at least two paths which are normal to each other. Advantageously, longitudinal relative motion between adjacent ones of the segments and between the optical fiber and the segments is allowed. As a result, the cable may be routed in tortuous paths under a carpet to service workstations as desired.

Abstract: A distributed trunked radio frequency (RF) switching network (switch) distributes audio routing control and processing throughout the switch, thus avoiding a centralized mixing matrix, increasing fault tolerance and providing low routing request latency time. Each audio source (e.g., RF repeater transmitter, dispatch console microphone) is preassigned an audio channel on a time division multiplexed (TDM) digitized audio network or bus. The audio sources continually broadcast digitized audio signals to all other nodes over the TDM network. Audio routing is performed at the audio destinations (e.g., nodes associated with RF repeater receivers, dispatch console speakers) by selectively "listening" to active TDM network channels. In the preferred embodiment, audio is routed unidirectionally on an "as needed" basis (e.g., in response to radio transceiver "keys" and "unkeys"), and audio routing pathways may change dynamically during an on-going call.

Abstract: In a semiconductor memory device having memory cells (21 i , 21 i+1  disposed at intersections of bit lines (BL,            BL     ¯           ) and word lines (WL i , WL i+1 ) and operating on an internal power source voltage (V D  ) which is lower than an external power source voltage for the memory device, sense amplifiers (41) are activated by a voltage on a drive common node (NS), and a comparator (110) is activated by the control signal (PAS) and compares the voltage on the common node (PS) with the internal power source voltage (V D ). The comparator has an output which is in a first state when the common node (PS) voltage is not higher than the reference voltage (V R ) and which is in a second state when the common node (PS) voltage exceeds the reference voltage (V R ). A latch circuit (120) is turned from a first state to a second state when the control signal (PAS) is turned active, thereby to activate the comparator (110) and a power source supply circuit (130, 132) which then supplies a drive voltage to the common node (PS). The latch circuit is turned from the first state to the second state when the output of the comparator (110) is turned to the second state. The latch circuit deactivates the comparator (110) when it is turned to the first state.

Abstract: To be able to transmit television pictures in a digital format on a medium having a limited bandwidth, the picture is subjected to some coding operation and thereby converted into a series of transmission bit blocks TRB n  of variable length (for example DCT and variable length coding). Each transmission bit block is divided into a main block H n  comprising at least the most important code words and an auxiliary block S n  comprising the other code words. By carrying out a formatting operation, a group of transmission bit blocks is converted into a channel bit block consisting of a number of sub-channel bit blocks SCB n  of equal length. The main blocks are accommodated at the first bit positions of the sub-channel bit blocks and the bits of the auxiliary blocks are spread over the remaining bit positions (Fig. 6E). It is thereby achieved that the most important information is always found at fixed locations so that the influence of sync losses is reduced considerably.

Abstract: A method of mixing a powder material and a binder in a predetermined ratio and kneading the mixture so that substantially whole surface of the powder particles are covered by the binder, molding the kneaded mixture into the shapes of desired products, then removing the binder from the moldings without causing expansion or cracks in the moldings before sintering. The binder comprises one or more organic binding substances soluble to an alcohol or to an mixed solvent of an alcohol and benzene or one or more ketones and one or more organic binding substances insoluble to the alcohol or to the mixed solvent. The moldings are put in contact with the alcohol or the mixed solvent to extract the organic binding substances soluble to the alcohol or to the mixed solvent from the moldings. The organic binding substances insoluble to the alcohol or to the mixed solvent are then removed by heat-decomposition. The dissolution of the organic binding substances soluble to the alcohol or to the mixed solvent can be controlled to an appropriate rate by the constituents of the mixed solvent and their ratio of mixture. 
     By this method, it is made possible to remove the binder from the moldings made of powders with small particle sizes and large specific surface areas, which are difficult to remove the binder from without causing defects by the conventional methods, in short time without causing expansion or cracks in them.

Abstract: When using as a plastics material a polyaniline which has been doped with a protonic acid, the difficulty is how to combine the melt-processability and neutrality of the material. A well processable, with a protonic acid doped polyaniline has heretofore always been so acidic that it has disturbed both the processing apparatus, and the environment as a finished product. It has now, anyhow, been invented a process for the preparation of a plastics material which is based on a doped polyaniline, wherein during or after bringing in contact a polyaniline or a derivative thereof and a protonic acid also a metal compound is admixed. The metal compound is preferably first reacted with a first acid, whereupon the obtained product is brought together with a blend or reaction product formed by a polyaniline or a derivative thereof and a second protonic acid. In the mentioned process as the metal compound e.g. zinc oxide is used, as the first acid preferably the same acid as for the second protonic acid, i.e. dodecylbenzenesulphonic acid, is used. The plastics mixture thus prepared is preferably brought together with a thermoplastic polymer such as a polyolefin, wherein a neutral, plastic, stabile plastics material having a low percolation threshold is obtained.

Abstract: A return line (20) for a probe station includes a sheet-like conductive strap (25) having a first end (52) connected electrically to a first probe (22) and a self-coiling second end (54) connected automatically detachably to a second probe (24), as by insertion of the second probe centrally within the coils of the second end (54). If the spacing between the probes (22,24) exceeds a maximum distance, the strap (25) harmlessly disconnects. The flat central portion of the strap (25) automatically tracks any reductions in the spacing between the probes, which enables fast probe travel and minimizes noise pickup. Preferably a spindle (104) rotatably engages the coiled probe (22) and has a post member (102) that carries the second end (54) of the strap to a far side of the probe to improve tip visibility and electrical connection during close-in probing. A process of making the strap (25) includes depositing layers of metal on a substrate using thin film technology. Self-coiling behavior of the strap is promoted by preheating the substrate (120) and by choosing, for one of the layers, a metal, thickness, and deposition process that will result in strong compressive forces acting internally in the layer. For ease of removal from the substrate, self-releasing behavior of the strap is promoted by providing an ultrasmooth substrate, a first layer material (128) that bonds weakly to the substrate but has a controllable thickness, and a second layer of material (132) that bonds variably to the substrate depending on the thickness of the first layer (128).
