Title: Speech synthesizer having an acoustic element database
Inventor: OLIVE JOSEPH PHILIP
IPC: G10L13/06
Filed: 1996-08-02
Abstract: A speech synthesis method employs an acoustic element database that is established from phonetic sequences occurring in an interval of a speech signal in establishing the database, trajectories are determined (220) for each of the phonetic sequences containing a phonetic segment that corresponds to a particular phoneme (210). A tolerance region is then identified based on a concentration of trajectories that correspond to different phoneme sequences (230). The acoustic elements for the database (260) are formed from portions of the phonetic sequences by identifying cut points (250) in the phonetic sequences which corespond to time points along the respective trajectories proximate the tolerance region (240). In this manner, it is possible to concatenate the acoustic elements having a common junction phonemes such that perceptible discontinuities at the junction phonemes are minimized.  Computationally simple and fast methods for determining the tolerance region are also disclosed.

Title: Animal foot trap
Inventor: ROSE HUGH QUENTIN
IPC: A01M23/34
Filed: 1996-09-20
Abstract: An animal trap consisting an anchored activating spring (16) with detachable safety catch (26), secured by tension to a trigger mechanism (10), and a partable noose (29). The cord of the noose (29) passes through the rings (19 and 21) on the ends of the upper and lower arms (20) and (18) of the spring (16) in a pulley--like arrangement and is fixed to the attachment (22).  The noose (29), constructed from soft but bite-resistant materials, incorporates a flat, leg-gripping part (30) containing a reusable, partable catch (31) and a resilient lock (37). When set, the noose (29) overlies the trigger means (14) so that when the latter is trodden on by an animal, the spring (16) is released and, pivoting in the channel (11), raises the noose (29) vertically up the animals leg, simultaneously tightening it. The spring (16) then separates from the trigger mechanism (10) to act as a cushioning spring, automatically releasing animals smaller or more powerful than the target animal.

Inventor: MURRAY LESLEY J
IPC: A61K35/12
Filed: 1996-10-29
Abstract: Myeloproliferative leukemia receptor (mpl) ligands, such as thrombopoietin, act on a primitive subpopulation of human stem cells having the characteristics of self-renewal and ability to give rise to all hematopoietic cell lineages. Thrombopoietin supports both megakaryocytic differentiation and primitive progenitor cell expansion of CD34+ and CD34 sub-populations (CD34+Lin-, CD34*Thy-1+Lin-, and CD34+Lin- Rh12310). Thrombopoietin also stimulates quiescent human stem cells to begin cycling. Thus, mpl ligands are useful for expanding primitive stem cells for restoration of hematopoietic capabilities and for providing modified human stem cells for gene therapy applications.
