Patent CA-2140273-C (CA)
Title: Tamper evident closure
Inventor: TANSEY CHARLES MARTIN
IPC: B65D55/02
Filed: 1993-07-14
Granted: 2002-07-09
Abstract: A container closer (10) particularly for use on screw top containers such as carbonated beverage containers, the container closure (10) having a generally cylindrical continuous tamper evident band (11) joined by a plurality of frangible bridges (13) to the free edge of a skirt (16) of the closure (10). The band (11) has a segmented internal rib (18) which engages an external retaining flange of the container when the closure (10) is applied to the container so that on removal of the closure (10) the tamper evident band (11) remains on the container or is visually clearly damaged by removal of the closure (10) from the container. The band (11) is provided with longitudinal reinforcement by projections (25 and 28) or other areas of thickening (26) to provide the band (11) with longitudinal stiffness while still permitting it to expand over the retaining flange on the container. The rib (18) has a first annular side (21), the first annular side (21) having a compound surface comprising a radially outer frusto-conical portion (23) which assists in the molding of the rib (18) and a radially inner substantially planar portion (24) which increases the difficulty of removing the closure (10) intact from the container without rupturing the bridges joining the tamper evident band (11) from the remainder of the closure (10).

Abstract: The present invention relates to a method and apparatus for identifying an examined object having a discernible boundary.  An image of the object is formed (34) and segmented into a plurality of pixels (36). The boundary of the object in the image is detected (40) and the parameters of the boundary pixels form an ordered sequence: p1...pk...pN, where p1 is the parameter value of the first boundary pixel; where pN is the parameter value of the last boundary pixel; N is the total number of boundary pixels and k is the index to the N pixels. The pk data point is determined (42) such that k satisfies the relationship (I): i-I/M < k/N <  i/M, where M is the total number of quantile partitions and i is the ith quantile partition. The object is identified based upon the pk data point value, which is the ith quantile in M partitions developed from the above relationship.

Title: Speech signal quantization using human auditory models in predictive coding systems
Inventor: CHEN JUIN-HWEY
IPC: G10L19/06
Filed: 1996-09-17
Granted: 2001-02-13
Abstract: A speech compression system called "Transform Predictive Coding", or TPC, provides for encoding 7 kHz wideband speech (16 kHz sampling) at a target bit-rate range of 16 to 32 kb/s (1 to 2 bits/sample). The system uses short-term and long-term prediction to remove the redundancy in speech. A prediction residual is transformed and coded in the frequency domain to take advantage of knowledge in human auditory perception. The TPC coder uses only open-loop quantization and therefore has a fairly low complexity. The speech quality of TPC is essentially transparent at 32 kb/s, very good at 24 kb/s, and acceptable at 16 kb/s.

Title: Bus monitor system

Granted: 2003-07-08
Abstract: BUS MONITOR SYSTEM        A bus monitor system comprises eight identical pro-grammable monitor circuits that are each connected to a monitored bus and to a local 16-bit event bus. There are three interfaces to they event bus within each monitor circuit. one interface asserts a predetermined bit pat-tern on the event bus when match conditions occur between bit patterns on the monitored bus and predetermined bit patterns stored in monitor circuit registers. A second interface asserts a signal on an external pin when bit patterns on the event bus match a predetermined bit pat-tern stored in a monitor circuit register. A third inter-face asserts a predetermined bit pattern on the event bus when an external device has asserted a signal on an ex-ternal pin. Each monitor circuit is capable of reading and asserting any of the bits of the event bus. The event bus is used to enable or disable monitor circuit inter-faces. If any asserted bit on the event bus matches a corresponding bit of one of the predetermined bit pat-terns stored in the interface enable and disable regis-ters, that interface will be enabled or disabled, respec-tively. The event bus gives the monitor system the abil-ity to simultaneously monitor for multiple bit patterns on the monitored bus, and to monitor for a sequence of bit patterns by halving one monitor circuit trigger another.
