Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units (15) such as bar code readers to a central computer (10) which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations (12, 13, 14), then sent by the base stations to the central computer (10) by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations (12, 13, 14), receiving only during a rigid time window following a transmission from the remote unit. The base stations (12, 13, 14) cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange.

Abstract: Beim Zuführen von Dosenzargen in den Wirkbereich einer Schweißeinheit ist es von wesentlicher Bedeutung, daß die zusammengehörigen Längsränder der Dosenzargen dem Schweißvorgang ohne gegenseitigen Versatz in Längsrichtung zugeführt werden. Um der genannten Forderung entsprechen zu können, wird der Vorschlag unterbreitet, die Transporteinheit für die Dosenzargen (1) lediglich aus einem zentral angeordneten Umlaufelement (5) aufzubauen. Die Mitnehmer, deren Längsmittelebene mit derjenigen der die Dosenzargen abstützenden Schiene (3) zusammenfällt und deren gegenseitiger Abstand (A+L) größer ist als die Länge (L) der Dosenzarge (1) in Föderrichtung, sind - in der Mitnahmestellung in Draufsicht betrachtet - als Schwinge (18) mit der Förderrichtung (Pfeil 2) entgegengerichteten Schenkeln ausgebildet, welche über Schwenkachsen (5 b) mit dem Umlaufelement (5) in Verbindung stehen. Jede Schwinge (18) weist an ihrer in Förderrichtung weisenden Vorderseite als Mitnahmefläche zwei Vorschubzapfen auf, deren gegenseitiger Abstand größer ist als die Schienen-Breite und die in der Mitnahmestellung beiderseits neben den Längsrändern liegend gleichzeitig an eine Dosenzarge (1) anlegbar sind. Dabei weist jeder der Schwingen-Schenkel einen sich über die Schwenkachse hinaus erstreckenden Steuerarm auf, an dem eine Steuerfläche angebracht ist.

IPC: G01R23/15
Filed: 1990-11-02
Abstract: A photodetector produces an output signal in response to irradiation by an optical beam from a pulled laser. A delay unit delays the output signal for a period corresponding to one-half of one cycle of a beat frequency generated by interaction of two frequency components in the optical beam corresponding to two predetermined longitudinal modes of operation of the laser. A differential mixer subtractively combines the output of the photodetector with the output of the delay unit, to produce an output signal having the main profile of the laser pulses suppressed, and the beat frequency component, if present, amplified. A resonant circuit and amplifier may be provided to further amplify the beat frequency component. The output of the amplifier is integrated to produce a DC signal having a magnitude which corresponds to the amplitude of the beat frequency component. The DC signal is compared with a threshold value to discriminate between single and multi-mode operation of the laser. An optical shutter may be closed in response to sensed multi-longitudinal mode operation to block the laser beam and protect equipment which would otherwise be damaged thereby.

Abstract: A circular scan streak tube system (10) for recording fast optical data includes a target (30) having a first array of detection elements (32) and a second array of corresponding storage elements (34). Changes in the scanning electron beam current representing optical events are detected and stored in the first array (32). The first and second arrays are segmented into two halves for continuous operation. Data stored in one half of the first array are transferred into the corresponding storage elements while data are written into the other half of the first array. Data stored in the first array are transferred in parallel to the second array. After a triggering event, the data are shifted circumferentially through the second array for output as serial data. The target is formed in a unitary planar semiconductor substrate (70) having a buried channel (72) for storing and conducting electric charge representing the stored data.

Abstract: A code-excited linear-predictive (CELP) coder for speech or audio transmission at compressed (e.g., 16 kb/s) data rates is adapted for low-delay (e.g., less than 'five ms. per vector) coding by performing spectral analysis of at least a portion of a previous frame of simulated decoded speech to determine a synthesis filter of a much higher order than conventionally used for decoding synthesis and then transmitting only the index for the vector which produces the lowest internal error signal. In other contexts, performing less critical portions of analysis on a previous frame of data has been termed "backward-adaptive". Two types of gain adaptation are used in respective implementations, both of which are backward-adaptive and one of which is dynamic to the extent that weighting coefficients are iteration-dependent. The spectral analysis is twentieth-order to fiftieth-order linear prediction analysis. Pseudo-Gray coding is used to reduce errors induced by channel noise; and the effects of the gain and specrtral analyses are taken into account in the training procedures which determine the sets of vectors which are the reference or candidate excitation vectors.

Abstract: An apparatus comprising a Viterbi decoder which decodes received convolutional code data in accordance with the Viterbi algorithm and provides path metrics. Among the path metrics, a path metric comparator detects the maximum and minimum path metrics for each data symbol. The path metric comparator selects the minimum difference among differences between the maximum and minimum path metrics. An apparatus also comprises a field strength detector which detects the electromagnetic field strength of a radio signal containing the convolutional code data. Upon the minimum path metric difference and the field strength, an interference detector checks if interference exists in the radio signal. The minimum path metric difference may be used for an antenna diversity system.
