Assignee:

The Regents of the University of California - Oakland CA

International Classification:

G01C 916

US Classification:

33395, 33365

Abstract:

A tiltmeter device having a pair of orthogonally disposed tilt sensors that are levelable within an inner housing containing the sensors. An outer housing can be rotated to level at least one of the sensor pair while the inner housing can be rotated to level the other sensor of the pair. The sensors are typically rotated up to about plus or minus 100 degrees. The device is effective for measuring tilts in a wide range of angles of inclination of wells and can be employed to level a platform containing a third sensor.

Appl. No.:

09/419033

Inventors:

Steven L. Hunter - Livermore CA

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

G01P 1500

US Classification:

7351403, 7351409

Abstract:

A rate sensor for angular/rotational acceleration includes a housing defining a fluid cavity essentially completely filled with an electrolyte fluid. Within the housing, such as a toroid, ions in the fluid are swept during movement from an excitation electrode toward one of two output electrodes to provide a signal for directional rotation. One or more ground electrodes within the housing serve to neutralize ions, thus preventing any effect at the other output electrode.

Abstract:

Techniques for customizing draw styles of widgets to better accommodate a user's direct manipulation needs. A user can customize various attributes of a widget and its manipulators to suit the user's needs. The customizations are stored as a style. The stored style can subsequently be applied to the widget to control the appearance and behavior of the widget. Stored styles may be applied to other widgets and can also be shared between users.

Assignee:

Pixar - Emeryville CA

International Classification:

G06T 15/70

US Classification:

345473

Abstract:

A system and method enables animators to pose character models' feet. An initial foot model position is received. The initial foot model position specifies a foot model contact point. One or more foot roll parameters are specified that change the relative angle between at least a portion of the foot model and an initial orientation of an alignment plane. Foot roll parameters specify the rotation of the foot model around foot model contact points. Foot roll parameters can include heel roll, ball roll, and toe roll, which specify the rotation of the foot model around contact points on the heel, ball, and toe, respectively, of a foot model. To maintain the position of the foot model contact point, the foot model position is adjusted based on the foot roll parameter. The repositioned foot model is realigned with alignment plane, which restores contact at the foot model contact point.
