US Patent:

6418240, Jul 9, 2002

Filed:

Dec 3, 1997

Appl. No.:

08/984450

Inventors:

Raymond Yu - Fremont CA

Assignee:

Alaris Inc. - Fremont CA

International Classification:

G06K 936

US Classification:

382232, 382236, 3484301

Abstract:

A method and apparatus for performing multiple frame image compression and decompression of motion video data are provided. In one embodiment, a plurality of sequential frames in a motion video sequence are collected and digitally filtered as a single image. At least some of the results of the digital filtering are then encoded to generate compressed data. In another embodiment, a plurality of sequential frames are filtered as if the boundary of each frame is adjacent to a boundary in the same spatial location of another of the plurality of sequential frames.

Appl. No.:

10/999064

Inventors:

Raymond Yu - San Jose CA, US

Assignee:

Immersion Corporation - San Jose CA

International Classification:

G06F 3/033

US Classification:

345161, 345156, 345157

Abstract:

A device comprises a manipulandum moveable in at least two degrees of freedom including a first link rotatably moveable about a pivot axis and a second link rotatably moveable about a pivot axis. The first link and the second link are coupled to a ground member. A first actuator is configured to engage the first link and provide an output about a drive axis of the first actuator. A second actuator is configured to engage the second link and provide an output about a drive axis of the second actuator. The drive axis of the first actuator is substantially parallel to the drive axis of the second actuator. The first actuator and the second actuator are each configured to receive a signal associated with a force feedback. The force feedback being associated with the manipulandum.

International Classification:

G09G 5/08
G06F 3/00

US Classification:

345167, 715701

Abstract:

Systems and methods for providing a haptic manipulandum are described. In one described system, a lever arm is pivotably coupled to a housing, and configured to apply a processor-controlled force to a substantially-spherical manipulandum to provide a haptic effect. The described system may include a processor in communication with an actuator for providing the haptic effect.

International Classification:

B60L 7/00

US Classification:

188161000

Abstract:

Systems and methods for providing resistive and vibrotactile feedback from a single actuator are described. One described system comprises a manipulandum, and a resistive haptic actuator configured to generate a resistive haptic force in order to generate a vibrotactile haptic effect.
