Title: Recognizing speech by using wavelet transform and transient response therefrom
Inventor: HUI SIEW KOK
IPC: G10L25/27
Filed: 1992-11-13
Abstract: Wavelet transform means 35 decomposes digitized input speech templates into energy vectors represented by coefficients assigned to fundamental building blocks; a plurality of the wavelet coefficients represents speech signals in time, scale and frequency domains. A profile of the input speech utterance is then constructed by accumulating the energy vectors in blocks. At the same time, the transient response of the energy vectors are also obtained 50. The transient response is the difference in the magnitude of an energy vector and that of the adjoining block. With the transient response, the input speech templates are aligned with those of the reference templates in the library 65 without having to time warp the time axis of the respective templates. The distance between the transient response of a test template and that of a reference template is then checked 60. If a threshold is exceeded, then there is no matching. <IMAGE>

Title: Multi-compartment container with mixing means
Inventor: WATSON GAVIN ROBERT
IPC: A61J1/00
Filed: 1996-01-31
Abstract: A container 5 is adapted to store at least two different ingredients in isolation. The ingredients are stored in compartments defined by projecting members (14), that project radially inward from the interior of the container wall 9, and extend for the length of the container. These members do not extend to the centre of the container, instead abutting with a central plugging means 10, coaxial with the longitudinal axis of the container, which seals the compartments. The plugging means may be flexible, for example a membrane or inflatable diaphragm, or inflexible, such as a cork. The plugging means may be released by pulling an attached cord 11, that may be connected to the cap 6 of the container, or to a ringpull (57), thus unsealing the compartments and allowing the ingredients to mix. Another embodiment comprises a container with a teat (77) that forms both the outlet and the plugging means. An annular compartment (63) is defined by an annular projecting member (71), and is sealed by a section of the inwardly extending teat, keeping it isolated from the main volume. The container is opened by pulling the teat outwards, thus breaking the seal, allowing the ingredients in the compartment and the main volume to mix.

Patent GB-2314139-A (GB)
Title: Shaft encoder with adjustable backlash compensation
Inventor: SMITH MICHAEL
IPC: F16D1/12
Filed: 1996-06-13
Abstract: To overcome the problem of backlash in a shaft encoder, the shaft encoder disc 3 rotates on its own bearing 2 and is driven by a pin of a drive pin assembly 5, 6 which cooperates with a slot in the shaft encoder disc. The length of this slot is equal to the backlash of a leadscrew 13. Rotating the leadscrew in one direction causes the drive pin to drive the encoder disc 3 producing an output from the encoder. When the direction of rotation of the leadscrew 13 is reversed the pin will move in the slot and as the length of this slot is equal to the backlash there will be no output until the backlash has run out and the drive pin will once again drive the encoder disc producing an output. The number of slots on the disc depends on the pitch of the leadscrew.
