IPC: A61N1/32
Filed: 1990-04-06
Abstract: Transcutaneous electric nerve stimulator for producing in a predetermined sequence different types of waveforms (in which the frequency varies, the signal is successively and/or intermittently created, etc.). When the user depresses a predetermined switch (SW0-SW5) while a desired waveform is being outputted, a low-frequency signal of the waveform is thereafter continuously produced. 
     The transcutaneous electric nerve stimulator is capable of selectively producing low-frequency signals of at least two different kinds, and a kind of output signals at a termination of a treatment is stored in a memory (6) such that a low-frequency signal of the stored kind is produced when the stimulater is started for a subsequent treatment.

Abstract: An electronic stimulating device is disclosed, with the stimulating device particularly illustrated being a transcutaneous nerve stimulating (TENS) device for effecting suppression of pain by nerve fiber stimulation. Biphasic constant current output pulses are applied to a user through electrode pairs (32,33;35,36) noninvasively positioned at the skin of the user. Microprocessor generated control pulses control generation of the biphasic output pulses at a biphasic output stage associated with each electrode pair, and the generated biphasic output pulses are capacitively coupled from each output stage which also includes a bleeder network (92,93) for effecting capacitor discharge. Stimulation may be continuously applied at a level selected by the user or may be applied in timed varying intensities the maximum level of which is selectable, and displays (23,30) of intensity and sensed faults, including low battery voltage, are also provided.

Abstract: A process for chemically resolving a mixture of enantiomers of primary amines, such as enantiomers of 1,3-dimethyl-5-methoxyoxindolylethylamine, provides one of the enantiomers in the form of a tartaric acid salt. In carrying out the process, an enantiomeric mixture is contacted with a chiral acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The resulting precipitate can then be recovered. The chiral acid is selected from the group consisting of dibenzoyl-D-tartaric acid, dibenzoyl-L-tartaric acid, ditoluoyl-D-tartaric acid, and ditoluoyl-L-tartaric acid. The precipitates can be used in the synthesis of stereospecific forms of physostigmine.

Abstract: A method for decoding bar code symbols in which a bar code reader and associated components scan a bar code symbol produce a representation of the symbol, and attempt to decode that representation in order to produce a character message. The method consists of the steps of storing a first representation of the bar code symbol corresponding to a first scan path through a first portion of said symbol smaller than the entire symbol, and storing a second representation of the bar code symbol corresponding to a second scan path through the symbol. The method then processes said representations in the event a successful decode has not taken place by utilizing the signal from a first scan with the signal from a subsequent scan to determine whether the information from successive scans can be concatenated to form a combined signal. The process is repeated with different subsequent scans until successful decoding of the combined signal.

An axially projecting annular web (8) is moulded on from the base of an annular space (7) formed by the outer and inner edges (4 and 5) of the lid. When the lid (1) is closed, said annular web introduces axial forces, caused by stacking, dropping etc., directly into the barrel neck (3). Arranged on both sides of the annular web (8) are sealing rings (13) which rest with prestress on the opening edge (14) of the barrel neck (3) when the lid (1) is closed.

Abstract: A predetermined number of logical page addresses are effectively translated into corresponding real ones. The number of the logical page addresses is determined by (M+N) bits and, each of the logical page addresses includes upper M-bit and lower N-bit. Logical page address registers, whose number is equal to 2 N , are provided to respectively store the predetermined number of logical page addresses applied. Address translation buffers (whose number is also equal to 2 N ) each stores 2 M  real page addresses which are grouped according to each of the lower N bits. The address translation buffers receive the upper M-bit of one of the logical page addresses, and output real addresses. An address translation controller receives the outputs of the address translation buffers and also receives the lower N-bit, and selects the real page addresses using the lower N-bit. The selected real page addresses are applied to a plurality of real address registers. A page number comparator determines whether or not the upper M-bit of one of the logical page address coincides with the upper M-bit of each of the remaining logical page addresses. The page number comparator outputs the comparison results which allow the real address(es) stored in the real address registers to be applied to a main memory.

Abstract: A disk drive within the dimensional confines of a form factor can optimise volumetric density by using the full height dimension to house disks (13), but must thereafter utilise the remaining space for electrical components. The structure shown uses a stack of parallel cards with an interface card (84) on the rear end wall to provide the principal drive control and data circuits outside the head-disk assembly (HDA; 13). The motor driver circuitry (107, 111) is mounted on a flat flexible cable (72) and is secured to the front wall (18) at the opposite end of the drive in heat transfer relation. The heat generating motor drive circuits are physically isolated from the data/control circuits by the frame and HDA while some of the printed circuit cards are secured to the frame in a manner that enhances rigidity; the allocation of modules to the cards anticipates flow of data and control signals so as to minimise the number of connections and signal delays that impair performance.

Abstract: The invention relates to methods and apparatus for regulating traffic in a Broadband Integrated Services Digital Network (B-ISDN) 30. Terminal adapters 20,21 interface between terminals 10,11 and the B-ISDN 30. Whenever a first terminal 10 wishes to transmit a data message to a second terminal 11, the source adapter 20, connected to the first terminal, allocates transmit bandwidth for the transmission of the message and sends a request message to a destination adapter 21, connected to the second terminal, for checking availability of and allocating receive bandwidth. The data message is sent only if bandwidth has been allocated on both ends. Overflow traffic is throttled at the adapters before it enters the network, thereby reducing the number of data cells lost because of the limited storage of the network.

Abstract: Programmable logic devices which include multiple blocks of combinatorial function generators and storage elements, and which are interconnected by a programmable interconnect structure are used, among other things for performing arithmetic functions which use logic for generating the carry function. When a large number of bits is to be processed, the carry function typically causes significant delay or requires significant additional components to achieve a result at high speed. The present invention provides dedicated hardware within the logic blocks for performing the carry function quickly and with a minimum number of components. The invention takes advantage of the fact that a carry signal to be added to two bits can be propagated to the next more significant bit when the two binary bits to be added are unequal, and that one of the bits can serve as the carry signal when the bits are equal.
