Title: File structure for a non-volatile semiconductor memory
Inventor: ROBINSON KURT BRIAN
IPC: G11C16/34
Filed: 1991-11-25
Abstract: A non-volatile semiconductor memory comprises an active block for storing a first file, a reserve block for storing a second file, and a directory block. The second file is a copy of the first file. The copy is made during a clean-up operation prior to erasure of the active block. The directory block comprises a directory entry for identifying the first file. The file structure allows flash EEPROMS to be used as mass storage (eg: instead of magnetic disks). Non-deleted files are duplicated in a reserve block before the active block is erased. This enables the space occupied by deleted files in the active block to be released during the clean-up operation. <IMAGE>

Title: Bar code printer
Inventor: FUJII KENICHI
IPC: G06K1/12
Filed: 1992-02-28
Abstract: In a printer (2) capable of efficiently creating and printing bar code symbols in various versions thereof, the dot pattern is copied in the bar height direction by the number of rows required to print the bar code of the specified height. Typical patterns are predetermined and stored in a ROM (8). The printer (2) is capable of handling such bar codes as CODE 39 in which the patterns for different digits can be defined independently of each other, or such bar codes as ITF and WPC in which the pattern for each digit is defined according to prescribed rules. In case of WPC, when a flag code and the number of dots to form a minimum module are specified from an external device (1), a dot pattern for one row for each digit of a bar code is created and held within the printer, and when these conditions are not specified from the external device (1), predetermined values are adopted to create the dot pattern for each digit. <IMAGE>

Filed: 1992-06-03
Abstract: The operation of a driving system for a cigarette packing machine, wherein the driving system has a rotary main drive (18, Figure 1, for driving a conveyor) and several slave drives 37, 38, 39 electrically connected to the main drive, is controlled in such a way that any selected slave drive can be disconnected from, decelerated to zero speed, accelerated from zero speed to normal speed and reconnected into the drive system in predetermined angular positions of the main drive. Each slave drive transmits motion to one or more movable parts or units of the packing machine in a synchronised manner. Disconnection of a slave drive occurs when a defect in an array of cigarettes is detected such as by a monitoring device 41. Other monitoring devices include one (48, Figure 6) associated with the main drive to transmit signals denoting the actual angular position thereof for comparison with the predetermined values. <IMAGE>

Title: Connecting computers and peripheral devices
Inventor: MCATEER LEANDRE EDWARD AUGUSTI
IPC: H04L12/40
Filed: 1992-06-08
Abstract: An electronic circuit which includes interpretive circuitry, permits standard computers to be networked using RS485 lines convened to RS232 for connection to their serial interface, all linked to one serial port on the main host computer. The circuit also links the 'slave' computers to machinery, which can be controlled and monitored by the computers by means of serial information. The circuitry permits the host to communicate with one slave at anyone time. The slave can either communicate with the network OR the machinery it controls, but not both at the same time. Information received from the machinery can be transferred to the host along an RS485 line into one RS232 serial port of the host computer. This can then be used and manipulated by the host or any other computer using standard operating systems and programming languages. <IMAGE>

Title: A method and an arrangement of estimating transmitted symbols at a receiver in digital signal transmission
Inventor: LARSSON LARS GUSTAV
IPC: H04B7/005
Filed: 1993-05-28
Abstract: In a digital time-shared radio transmission system, a radio receiver (14) receives a signal (R(T)) whose symbol frequency (1/TS) is lower than the channel bandwidth of the system. A correlating and sampling circuit (15) receives a baseband signal (y(T)) samples (21) the signal eight times (y(k/8)) with each symbol time (TS), performs channel correlation (23), generates a channel estimate (HF) and samples down the once sampled signal (y(k/8)) to an observed signal (y(k/2)) with two values for each symbol time (TS). A channel equalizer (17) executes a fractional viterbi algorithm which utilizes two delta-metric values for each state transition and generates estimated symbols (@, D(k)). A channel estimating filter (31) receives a symbol sequence of alternating zero-value symbols  OMEGA and the estimated symbols (@, D(k)) and generates an estimated signal (y(k(2)). The channel estimating filter (31) is adapted (34) with the aid of an error signal (e(k/2) = y(k/2)-@, (k/2)) and the filter delivers a channel estimate (H(k(2)) to the channel equalizer (17). Weighting factors ( alpha  (k2)) are generated (35) with the aid of the error signal (e(k/ 2) and the two aforementioned delta-metric values are coweighted to a common delta-metric value with the aid of the weighting factors ( alpha (k/2)), this common delta-metric value being used to generate the estimated symbols (@, D(k)). The use of the weighting factors ( alpha  (k/2)) improves the metric calculation and enables the channel estimating filter (31) and the channel equalizer (17) to be relatively simple. The insertion of the zero-value symbols ( OMEGA ) simplifies the generation of the weighting factors ( alpha  k/2)) and the adaptation (34) of the channel estimating filter (31). <IMAGE>
