Granted: 2006-03-21
Abstract: A post-processor (317) and method substantially for enhancing synthesized speech is disclosed. The post-processor (317) operates on a signal ex(n) derived from an excitation generator (211) typically comprisi ng a fixed code book (203) and an adaptive code book (204), the signal ex(n) being formed from the addition of scaled outputs from the fixed code book (203) and adaptive code book (204). The post-processor operates on ex(n) by adding to it a scaled signal pv(n) deriv ed from the adaptive code book (204). A gain or scale factor p is determined by the speech coefficients input to the excitation generator (211). The combined signal ex(n) + pv(n) is normalised by unit (316) and input to an LPC or speech synthesis filter (208), prior to being input to an audio processing unit (209).

Abstract: L'invention permet de doser la puissance calorifique d'une installation de production combinée de chaleur et d'électricité par simple modification du régime, ce qui permet de maintenir les organes de régulation du moteur thermique dans la plage d'efficacité maximale. A cet effet, le moteur thermique dans sa position de pleine charge ou à son niveau optimal d'efficacité est amené à une vitesse inférieure ou supérieure de rotation uniquement par une réduction ou une augmentation respective du courant électrique fourni au réseau d'électricité, ce qui n'affecte guère le degré d'efficacité du moteur thermique. Le courant électrique peut être maintenu à la fréquence voulue par des convertisseurs de fréquence.

Title: Method and apparatus for interactively creating new arrangements for musical compositions
Inventor: GERSHEN JOSEPH S
IPC: G10H1/00
Filed: 1996-12-04
Granted: 2004-01-27
Abstract: The musical work is represented on a digital medium in the form of a database (150) comprising a plurality of fixed musical sequences, and a template comprising a plurality of sequence positions. Each sequence position may represent one track of a musical arrangement, such as the performance of one instrumental group, or a musical solo. The various tracks are intended to be played simultaneously, in parallel. In fixed-addition, some of the sequence positions may represent length, partial segments of a single track that are intended to be played serially. Using a menu-driven, graphical interface, a user interactively selects a plurality of the fixed musical sequences, as desired, and allocates the selected sequences among the various fixed sequence positions specified by the template. The musical sequences are then combined in accordance with the user's selections, thus creating a new arrangement of the musical work. In this way, users of varying levels of sophistication can be given a musically structured framework for interactively constructing new arrangements of recorded musical works.

Abstract: A decompression panel assembly (12) for use in an aircraft separation structure (14). The panel assembly includes a support pan (26) having an opening (28), a bull nose (64) extending outwardly from the support pan at the opening's edge, and a recess (62) surrounding the bull nose. An inner seal (70) is sized and located within the recess (62). A retaining ring (22) is provided and includes a number of fingers (84) formed from spaced-apart slits (86) extending into the retaining ring (22) from the ring's inner edge. The assembly (12) further includes a pressure relief panel (24) shaped similar to the support pan opening shape, though sized slightly larger. The pressure relief panel (24) is held between the support pan bull nose (64) and the retaining ring (22) during non-decompression use. A number of index pins (94) interconnect between the retaining ring and the support pan. A grill (30) is attached to the support pan to protect the pressure relief panel. During a rapid decompression event, the retaining ring fingers (84) flex slightly to reduce the holding force applied to the pressure relief panel (24), thus allowing the pressure relief panel to quickly and entirely detach from the assembly (12).

Filed: 1997-07-25
Granted: 2006-10-10
Abstract: A unidirectional roller chain sprocket (112) for use primarily in automotive engine drive chain applications which incorporates an asymmetrical tooth for improved noise reduction. The sprocket (112) includes a first plurality of sprocket teeth (132) each having a first engaging flank (134) with a first contact point at which a roller (128) contacts the first engaging flank (134), and a second plurality of sprocket teeth (136) each having a second engaging flank with a second contact point at which a roller (128) contacts the second engaging flank. The first engaging flanks (134) include a flank flat (144) which facilitates spacing the first contact point on the first engaging flank (134) relative to the second contact point on the second engaging flank to effect a time delay between an initial roller to first sprocket tooth contact and an initial roller to second sprocket tooth contact. The flank flat (144) is tangent to an engaging flank radius Rf and a first root radius. The asymmetrical tooth profile may also incorporate one or more inclined root surfaces which provide tooth space clearance for maintaining the chain rollers in hard contact with the root surface in the sprocket wrap. or added pitch mismatch wherein the sprocket chordal pitch is less than the chain link pitch to facilitate a "staged" roller-tooth contact as a roller (128) moves into full mesh from an initial tangential impact at the flank flat (144).

Granted: 2003-12-16
Abstract: A method is disclosed for accessing a removable storage medium. The removable storage medium is inserted within a removable storage drive. When the newly inserted removable storage medium is detected, an identifier is read therefrom. The identifier is used to determine if a symbolic link to that medium already exists. When a symbolic link exists, the symbolic link is updated to reflect the physical path to the storage medium. When the symbolic link does not exist, a symbolic link is created linking the identifier to the storage medium. The symbolic link indicates a non-standard storage medium. The symbolic link is then used to read data from and write data to the storage medium.
