Filed: 1993-04-02
Granted: 2001-12-18
Abstract: A method and apparatus for video editing, in which video clips (and optionally also still image and audio clips) are stored as digital data in a computer memory, selected clips are displayed in elongated tracks on a display screen, and editing operations are performed on the clips in response to manipulation of displayed cursors and icons to assemble and preview an edited video program.      Preferably, the inventive apparatus is a computer system programmed to display video, still image, and audio clips, and special effect icons, in tracks along a displayed time line. The system assembles a video program from stored clips in response to arrangement of displayed clips and special effect icons in a desired sequence along the time line. The computer system is preferably programmed to select a new in or out point for a clip by positioning a cursor at an edge of the displayed clip and dragging the edge relative to the time line, to select a special effect transition between displayed clips by positioning a transition icon in a special track in alignment with overlapping portions of the clips, to select special effect parameters by manipulating an icon in a special effects track, to filter selected video clips with a mosaic filter having user-selectable time-varying filter characteristics, and to control superimposition of an overlay clip with a main clip in response to manipulation of a level control icon displayed in alignment with the overlay clip.

Abstract: An elevator motor provided with an external rotor and a traction sheave is so implemented that it simultaneously constitutes the counterweight of a rope-suspended elevator. The elevator motor is mounted to one of the side platesof the counterweight, so that this side plate acts simultaneously as a supporting structure of the motor and as a frame of the counterweight. In this motor/counterweight structure, rotating induction motors can be used. A gear is not necessary because the construction of the invention and the placement of the motor allow the use of a motor with a large diameter and therefore a high torque. As the length of the motor still remains small, the motor/counterweight of the invention can be accommodated in the space normally reserved for a counterweight in an elevator shaft.

Title: Selective control valve system with float
Inventor: MILLER MATTHEW THOMAS
IPC: F15B11/08
Filed: 1994-03-22
Granted: 1998-09-01
Abstract: A pilot operated directional control valve communicates fluid between a hydraulic actuator, a pump and a reservoir.  A lockout valve is connected between each main control valve work port and a corresponding cylinder port, and operates to reduce fluid leakage therefrom.  Each lockout valve includes a pressure responsive poppet valve member which is exposed to fluid pressure in a lockout chamber.  A vent control valve is connected between each lockout valve and a corresponding one of the pilot valves.  Each vent control valve includes a vent check valve which controls fluid venting from the lockout chamber and a vent piston which is biased to urge the vent check valve to a closed position thereby trapping fluid in the lockout chamber.  When both pilot valves are energized, both lockout valves are vented and a float valve moves to a position wherein both cylinder ports are communicated, via the lockout valves and the float valve, with each other and with the reservoir.  The float function is obtained without the requirement of additional solenoids or by compromising the available modulation range of the main control valve.

Abstract: In a multipulse processing device for achieving a high encoding efficiency without using a high sampling frequency for an input signal and with a great degree of freedom given to positions of multipulses, an input speech signal is subjected by an LPC analyzer/processor 3 to LPC analysis of each analysis frame for extraction of LPC coefficients after sampled by an A/D converter 2.      Multipulses are retrieved as a result of decision by a multipulse analyzer 20 with a degree of freedom given relative to sampling points of a sampled speech signal supplied through an auditorily weighting filter 4.      Encoded by an encoder 41 and together with k parameters used as an example of the LPC coefficients, retrieved multipulses are multiplexed by a multiplexer 42 for delivery to a synthesis side. A multipulse waveform synthesizer 45 synthesizes a waveform by using decoded multipulse data and the LPC coefficients.

Granted: 2004-07-27
Abstract: A method and system for dynamically generating object connections is provided. In a preferred embodiment, a connection can be generated between a source object and a sink object using a connection point object. A source object has connection point objects where each connection point object corresponds to a particular interface. A sink object implements one or more notification interfaces for connecting to a source object. A connection point object of a source object can connect to multiple notification interfaces, which belong to one or more sink objects. A connection point object keeps track of pointers to the notification interfaces to which it has been connected. In order to generate a connection, a sink object requests from a source object a connection point object corresponding to a particular interface. The source object determines whether it supports such a connection point object, and if so returns a pointer to the connection point interface of the determined connection point object. The sink object then requests to be connected to the connection point object using the returned connection point interface pointer and passes a reference to a notification interface of the sink object corresponding to the particular interface. The connection point object then stores the reference to the notification interface of the sink object, creating a connection between the sink object and the source object. At some later time, the source object can utilize the connection to notify the sink object through the connected notification interfaces.

Abstract: Un système de bus de communication à canal unique et multistation peut accueillir des stations maîtresses et des stations esclaves. Une station maîtresse arbitre, détecte le résultat d'arbitrage, et formate. Un bloc possède une adresse esclave et des signaux de commande esclaves et peut accueillir une pluralité de périodes d'octets de données jusqu'à un premier maximum, chaque période comprenant un bit d'accusé de réception. En l'absence du bit d'accusé de réception, l'octet de données associé est répété. Pour un transfert prévu d'un message dont la longueur d'octet de données dépasserait ce premier maximum, le message est divisé en messages partiels dont chaque nombre d'octets de données de blocs associés est inférieur à ce premier maximum, et ce message est assigné à un bloc de bus respectif. Pour chaque bloc, à la fois les périodes d'octets et les bits d'accusé de réception reçus sont comptés. Si le premier maximum est atteint par ce nombre de périodes d'octets de données avant que le comptage d'octets de données du bloc ne soit atteint par le nombre de bits d'accusé de réception, le bloc a alors échoué. Tout transfert dans ce bloc est ensuite ignoré et une répétition est  effectuée.
