Title: Digitizer for bar code reader
Inventor: BRIDGELALL RAJ
IPC: G06K7/00
Filed: 1994-10-31
Abstract: ABSTRACT      A multi-bit digitizer  (30)  for a barcode reader detects  the presence  of  edges  of  a  scanned barcode symbol, and also measures the strength of each detected edge.  A polarity or edge direction signal (8) indicates the direction of each detected edge, and a timing signal (6) is representative of the timing and also, by means of a variable pulse width, the strength of each edge.   A gating  signal  (200)  indicates  that  the  data  are unreliable and invalid if the measured voltage applied to the scanner motor of the barcode reader is higher or lower than defined limit values.  Any scans made at a speed which were too high or too low are rejected.

Title: Method for detecting erasures
Inventor: SPRUYT PAUL
IPC: H04L1/00
Filed: 1995-04-18
Abstract: ABSTRACT                METHOD FOR DETECTING ERASURES A method is described for detecting erasures in a stream of  sets  of  digital  signal  values  received  at  a receiver side after transmission from a transmission side. Subsets of these sets are modulated on distinct carrier signals, each transmitted and received thus modulated carrier signal corresponding to one of a number of predetermined subset related points and to a receipt point on a carrier dependent  modulation  representing  map  respectively.  The method includes the steps of: - selecting  for  each  receipt  point  the  nearest  of  the predetermined subset related points; - calculating a distance between the receipt point and the nearest subset related point and multiplying this distance with a map dependent weight factor; - summing  the  thus  obtained  weighted  distances  for  all subsets of a set; and - marking the latter set as an erasure when the thus obtained result exceeds a predetermined threshold.

Filed: 1995-09-15
Abstract: An identification device, particularly for the identification of persons such as babies or patients in hospital, is formed by a base sheet of a computer-printable material, preferably a fibre cloth resistant to tearing, with spaced parallel perforated separation lines extending laterally to form identification bands between successive separation lines. Each band has an identification region on which information can be printed by computer, and head and tail end regions between the identification region and the opposed longitudinal edges of the base sheet. An adhesive, such as a double-sided self-adhesive tape, is secured to the base sheet in the region of the head ends of the bands, with a backing sheet attached to the other side of the tape. The tape and backing sheet have perforations in register with the feeder holes adjacent each longitudinal edge of the base sheet. The bands can be computer printed in the hospital ward with information relating to the patient or mother and baby, and separated from the other bands to be applied to the person concerned, thereby reducing the risk of different information being written on the band from that held in the ward records.

Title: Sequencing and Error Detection of Template Instantiations During Compilation of C++ Programs
Inventor: STREETER DAVID JOSEPH
IPC: G06F19/00
Filed: 1996-06-12
Abstract: A priority queue is used to sequence template instantiations in compiling C+ + programs. If the analysis of a C+ + code fragment encounters a name that requires full instantiation and no matching full instantiation exists, the parse is terminated and rescheduled, and a full instantiation is scheduled as an antecedent of the failed parse. "Antecedent" means that the failed parse code fragment will not be reparsed until after the full instantiation has succeeded. Only when the full instantiation has succeeded will the terminated parse be reconsidered. Parsing full instantiations may causeadditional full instantiations. These are handled in the same manner; the additional instantiation is scheduled, and the current parse is failed and rescheduled. At the time of scheduling, the antecedent instantiation is marked with its dependent, so that the dependent chain give the chronology of the instantiation. This makes it easy to generate historical or "traceback" information for meaningful error messages.
