Granted: 1990-08-16
Abstract: Pour dépister des cassures du verre dans la région du goulot (1a; 1b) de bouteilles en verre par des procédés opto-électroniques, chaque bouteille (1) est mise en circulation sur un trajet semi-circulaire et est en même temps mise en rotation autour de son axe longitudinal (3). Sur son trajet semi-circulaire, la bouteille (1) est guidée à travers la marche des rayons d'un dispositif de mesure. Le faisceau de mesure (5) traverse obliquement l'axe longitudinal (3) de la bouteille, dans la région du goulot (1a, 1b). Le signal localisé de balayage fourni par le dispositif de mesure lors de chaque opération de balayage, correspondant à une position de rotation angulaire minimale de la bouteille (1), présente une modulation caractéristique de l'intensité. La présence d'une cassure du verre peut être reconnue par le fait que l'intensité maximale normalement détectée est absente au cas où le verre est cassé à cet endroit. L'absence d'intensité maximale est détectée par des procédés de mesure qui consistent à mesurer l'écart entre deux intensités maximales adjacentes et à comparer l'écart mesuré avec une valeur de référence.

Title: Block pattern detection circuit
IPC: G11B20/12
Filed: 1987-07-24
Granted: 1992-12-09
Abstract: Block pattern detection circuitry for the read subsystem of a streaming tape drive system comprises a state machine (20), a pattern decoder (30), a tape mark detector (40), a block/gap filter (50), a block/gap meter (60), a verify count section (10), and a block read/verify section (80). The incorporation of a hardware state machine (20) within the block detect circuitry permits the application of historical detect data in the interpretation of present detect data. This provides more certain pattern recognitions. Also, state data is fed back to the block/gap filter (50) allowing precise block boundary triggers which are used by position capture circuitry and the drive controller to effect more precise re-try positioning. The use of the block/gap filter (50) increases the detect circuitry's immunity to noise. The advantage is enhanced where the block/gap filter (50) uses stochastic thresholding, which is also advantageously employed by the tape mark detector (40).
