Abstract: A machine for producing a packaging filler material employing inflated pouches or cells fabricated from a tubular supply of plastic-like material having a top and bottom integral fold so that a pair of sheets are defined with their opposing inner surfaces establishing a compartment. Sealed strips, which are spaced apart in parallel relationship, define the sides of each pouch compartment. The machine includes a first work station having a source of tubular material that is introduced to a second or cutter station for severing the top fold of the tubular material followed by introduction to a third or inflation station where a source of pressurized fluid is fed to the pouch compartment. A sealing station follows the inflation station where the top opening to the pouch is closed such as by heat sealing. Idler rollers smoothly conduct the material past each of the respective work stations in a serial fashion and provide a gap for effecting inflation.

Abstract: A packaging filler product and machine for making the product wherein the product includes an air-filled pouch having sealed edges and spots connecting the opposing sheets of the pouch together. The machine includes a frictional belt system for gripping a bulk supply of pouched package material and that urges the bulk material past an inflation device for serially introducing air to the interior of each pouch of the package material followed by employing a heater that heat seals the opening into the interior of each pouch. A trim cutter eliminates unnecessary material and individual pouches are separated from the bulk supply by using perforations provided between adjacent pouches. A feed mechanism including the belt system is provided for moving the bulk supply of pouches from a supply spool past the heater and through the trim cutter. Tensioning and idle rollers guide the bulk supply of pouches through the machine in an in-line series.

Abstract: An improved small computer systems interface multiplexer (SCSI Mux II) provides for coupling of a computer on a local bus with shared peripheral devices on a global bus. The SCSI Mux II is accessed by a pseudo-operation code that includes two local bus identifiers as the identifier for the SCSI Mux II. Once the SCSI Mux II is identified, the computer accesses the SCSI Mux II as a local bus peripheral device and the SCSI Mux II couples the local bus to the global bus by translating the target peripheral device identification into a global identifier to complete the transfer between the computer and the designated shared peripheral device.

Abstract: A maximum likelihood detector using the Viterbi algorithm for estimating a sequence of data bits received over a communication channel. Depending on the constraint length (C), a plurality of different states is associated with the transmitted bits (e.g. 16 if C=4). The detector comprises various data sources relating respectively to state transition probabilities (branch metrics, previous partial path metrics) and observed values of the received bits. Means are provided for calculating the partial path metrics for each state using values from said data sources. The calculating means comprise a common adder/accumulator for performing repeated additive arithmetic operations and for storing the cumulative result thereof. Multiplexing means are also provided for selectively coupling the data sources in a predetermined order to the adder/accumulator to implement the partial path metric calculation.

Abstract: A method of receiving data transmitted in a burst-mode radio communications such as GSM. Prior to transmission a set of first data elements (bits) relating to a first message which may be associated with a first channel type (e.g. a traffic channel (TCH) in GSM) has selected bits substituted or "stolen" by data elements (bits) relating to a second message which may be associated with a second channel type (e.g. a fast associated channel FACCH in GSM). The data elements relating to the first and second messages are interleaved over the same or a different number of bursts. In a normal GSM traffic burst two single-bit flags are set to `1` to indicate respectively when the even bits or the odd bits of the burst have been stolen for FACCH data. A detector (5) is used to monitor the flags from the same number of bursts over which the FACCH is interleaved.

Abstract: An electrical connector for establishing a positive interconnection between a first set of electrical contacts and a second set of electrical contacts which employs the use of a receptacle section and a plug section. The receptacle section includes a collet receiving opening therein. The plug section includes a plurality of collet fingers which are to be locatable within the collet receiving opening and establishing a positive interlocking therewith. The collet fingers are integrally formed within a sleeve which has a drawbolt slideably mounted therein. The drawbolt is movable by a manual actuation means between an extended position and a retracted position. With the drawbolt in the extended position the collet fingers are capable of being deflected thereby permitting movement of the receptacle section with respect to the plug section.
