Title: System and method for determining pitch contours
Inventor: OLIVE JOSEPH PHILIP
IPC: G10L25/90
Filed: 1996-07-11
Granted: 2001-10-30
Abstract: A system and method are provided for automatically computing local pitch contours from textual input to produce pitch contours that closely mimic those found in natural speech. The methodology of the invention incorporates parameterized equations whose parameters can be estimated directly from natural speech recordings. That methodology incorporates a model based on the premise that pitch contours instantiating a particular pitch contour class can be described as distortions in the temporal and frequency domains of a single, underlying contour. After the nature of the pitch contour for different pitch contour classes has been established, a pitch contour can be predicted that closely models a natural speech contour for a synthetic speech utterance by adding the individual contours of the different intonational classes and adjusting the boundaries of these to match the boundaries of the adjacent intonation curves.

Abstract: A hydraulic inertial vibration isolator (1) is connected between a vibrating body (3) and an isolated body (5). The vibration isolator (1) comprises a cylinder (7) which includes two chambers (35, 37) and a piston (9) therebetween. The chambers (35, 37) are connected by a tuning passage (31) in which a solid tuning slug (33) is slidably disposed. The chambers (35, 37) and the tuning passage (31) are filled with liquid.  Bypass passages (57, 61) connecting the tuning passage (31) to the chambers (35, 37) allows file liquid pressure in the chambers (35, 37) to equalize when the amplitude of the tuning slug's oscillatory motion is sufficiently large, thereby limiting the tuning slug's amplitude. Dashpots (45, 47) axially disposed adjacent to either end of the tuning slug (33) act to damp excessive tuning slug motion and to bias the tuning slug (33) toward the center of the tuning passage (31). An electronic control system (69) is used to supply alternate current to magnetic coils (67) adjacent to the tuning slug (31), thereby matching the isolation frequency to the vibration frequency.

Abstract: A light weight, upholstered panel for use in modular and free standing office landscaping systems. The panels form free standing partitions which can be rearranged and assembled into an office system. Panels can be interconnected and positioned over a range of angles relative to adjacent panels. The panel core is composed of a light weight composite structural material with perimeter frame members along each edge. Each frame member has the same cross-section along its length. The horizontal perimeter horizontal frame members are inter-connected with the vertical frame members by corner connectors. The corner connectors have protrusions which engage hollow cavities in the ends of the frame members. The perimeter frame acts to transfer loads imposed on the panel to the structural core. The perimeter frame members incorporate formations to secure the panel fabric, trim and the inter-panel connection system in place and provide recesses for fasteners and support hardware.

Abstract: Un système compact est fourni pour l'élimination de liquide d'un flux de gaz sortant d'une tête de puits de gaz naturel. Le système présente un train de tiges d'entrée communiquant avec la tête de puits pour fournir le flux de gaz à partir de celle-ci. Un séparateur de gaz-liquide généralement cylindrique et allongé présente une entrée communiquant avec le train de tiges d'entrée pour y recevoir le flux de gaz. Le séparateur sépare le liquide du flux de gaz pour fournir un flux de gaz sec et stocke temporairement un volume prédéfini de liquide. Le séparateur comprend une chambre de séparation en communication fluidique avec l'entrée pour changer la vitesse du flux de gaz entrant, et au moins un élément de cloisonnement dans la chambre de séparation pour engager le flux de gaz afin de pousser le liquide à se fondre avec celui-ci et à tomber sous l'effet de la gravité vers une extrémité du séparateur. Une sortie du séparateur libère le flux de gaz sec vers un train de tiges de sortie pour transporter le flux de gaz sec vers un réseau de distribution de gaz. Un boîtier isolé loge le séparateur et au moins une partie des trains de tiges d'entrée et de sortie. Le boîtier est élevé au-dessus de la surface du sol et est entièrement supporté sur les trains de tiges d'entrée et de sortie. Une ouverture dans le boîtier permet au liquide de sortir du séparateur et du boîtier pour un déversement sur le sol ou une collecte ailleurs.

Abstract: A seat restraint system (110) whose torso belt (103) inflates upon impact to  protect the occupants of a vehicle such as an automobile. The inflating component of the present invention is a braided tube (101) linked to a gas generator and crash sensor. When an impact is detected, the gas generator is  ignited, inflating the braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube. The contracting tube pretensions the seat belt system by pulling any slack out of the seat belt system. The inflated structure restricts the forward motion of an occupant and distributes crash loads over a larger occupant surface area to reduce both primary and secondary injuries. In a si de impact the inflated structure restricts occupant motion, distributes crash loads and provides head protection.
