Title: Speech recognition system
Inventor: WATANABE SADAKAZU
IPC: G10L15/32
Filed: 1983-01-31
Granted: 1987-08-20
Abstract: An acoustic signal processing circuit extracts input speech pattern data and subsidiary feature data from an input speech signal. The input speech pattern data comprise frequency spectra, whereas the subsidiary feature data comprise phoneme and acoustic features. These data are then stored in a data buffer memory. The similarity measures between the input speech pattern data stored in the data buffer memory and reference speech pattern data stored in a dictionary memory are computed by a similarity computation circuit. When the largest similarity measure exceeds a first threshold value and when the difference between the largest similarity measure and the second largest measure exceeds a second threshold value, category data of the reference pattern which gives the largest similarity measure is produced by a control circuit to correspond to an input speech. When recognition cannot be performed, the categories of the reference speech patterns which respectively give the largest to mth similarity measures are respectively compared with the subsidiary feature data. In this manner, subsidiary feature recognition of the input voice is performed by a subsidiary feature recognition section.

Abstract: A one-piece plastics closure for a carbonated beverage bottle has a sealing ring (17) pivotally attached at the junction between its closure panel (10) and dependent skirt (11). The sealing ring is forked, having two annular and mutually divergent fins 20, 21.

Granted: 1991-08-22
Abstract: The invention relates to a coin sorter apparatus for sorting a group of mixed coins (11) by denomination and automatically terminating the sorting process in response to a sensed operating parameter. Sorting is provided by a stationary disc (21) and a rotating disc (19) positioned sufficiently proximate to one another so that when the group of mixed coins (11) are dropped into the centre opening of the stationary disc (21), they are rotated by the rotating disc (19) and guided by the stationary disc (21) on a radially outward spiral sorting path which exits each denomination of the coins at discrete locations (49) along the periphery of the stationary means. As the coins (11) are sorted, a sensing means (69) provides signals indicating the presence of a predetermined condition. A bridge guide (71) and a diverter guide (72), which are part of the stationary disc (21), are responsive to the signals from the sensing means (69) to redirect the radially outward sorting path of the coins (11) to a radially inward path so as to terminate the sorting process. Optionally, a circuit responsive to the sensing means (69) controls the application of power to the motor (37) powering the rotating disc (19) of the sorter apparatus and cuts off that power, when the sorting process is terminated in order to prevent abrasion of the re-circulating coins or damage to the sorter apparatus.
