Filed:

Mar 28, 2003

Appl. No.:

10/400287

Inventors:

Eric Long-Chia Chang - Irvine CA, US

International Classification:

A47B 27/00

US Classification:

248460, 248447, 248458

Abstract:

A portable easel comprises an easelback and palette box joined by two lockable hinges mounted on opposing sides, the hinges having friction washers, and having knobs extending outward from shafts of each hinge, the shafts defining a rotational axis. With knobs loosened, the easelback may be rotated to a desired angle relative to the palette box, and, with knobs tightened, the friction washers lock the easelback into position. The easelback further comprises a canvas-holder having a vertically adjustable slidable lower support plate and a vertically extendable shaft, said shaft having a horizontal cross member configured with rotatable hooks for securing a canvas. The palette box further comprises a right-angle baseplate for tripod connection to advantageously place the opened easel's center of gravity at the baseplate-to-tripod connection. The easelback may comprise slots for storing canvases, and the palette box may be configured with multiple compartments for storing paints and accessories.

G06F 17/30

US Classification:

707755, 707E17058

Abstract:

A system and method for searching for content in a user device includes a receiver receiving a plurality of data objects. The user device includes a search module comprising a parsing module parsing search data from the plurality of data objects and a memory interface module storing search data within a memory of the user device. The search module comprises a search performance module searching the search data in response to a search query. The search module comprises a search results module generating search results from the search data. The user device is associated with a display that displays the search results.

International Classification:

G03B 910

US Classification:

352214

Abstract:

A shutter system for a movie camera or the like for controlling the film exposure including a main shutter wheel rotatably mounted on main drive shaft driven by a first motor and at least one adjustable shutter wheel positioned adjacent to and coaxially rotating with the main shutter wheel, the adjustable shutter wheel being mounted on a secondary shaft independently driven by a second motor. Both the aperture (determined by the relative positions of the shutter wheels of the main shutter wheel and adjustable shutter wheel) and the shutter speed are set by a controller which regulates the speed of each of the motors.

International Classification:

G05B 1302
G06F 1518

US Classification:

364152

Abstract:

A heuristic control system and method for use with a computer-aided design, capable of learning complicated control and achieving an optimizing task with a fewer number of iteration. The heuristic control system includes: rule-based system for choosing and evaluating a rule among a plurality of given rules; training system for choosing strongly a rule whose evaluation result is favorable based on a predetermined value which evaluates an evaluation result of the rule-based system, and for generating a learning pattern; and neural network for designing an optimized circuit based on a signal fed from the training system and for sending a resultant signal to the rule-based system for another iteration of heuristic control. The learning method includes the steps of: choosing and evaluating a rule among a plurality of given rules; choosing strongly a rule whose evaluation result is favorable based on a predetermined value; generating a learning pattern which brings a desirable result based on the evaluating step; designing an optimized circuit based on the learning pattern generated; and choosing and evaluating iteratively a rule among a plurality of given rules.

Inventors:

- Monrovia CA, US
John Desjarlais - Pasadena CA, US
Eric Chang - Walnut CA, US

International Classification:

C07K 16/46

Abstract:

Novel Heterodimeric IgG-Like Bispecific Antibodies (HILBAs) are provided herein. Such bispecific antibodies are similar to IgG in structure and, thus, do not exhibit a limited half-life like previous antibody fragment-based bispecifics. Moreover, such heterodimeric IgG-like bispecific antibodies advantageously do not entail complicated generation methods such as Fab arm exchange and common light chain methods. Unlike canonical IgG antibodies, the HILBAs described herein include at least one monomer that is from N- to C-terminus: a VH-scFv linker-VL-CL-domain linker-CH1-hinge-CH2-CH3.

International Classification:

G06F 3/00

Abstract:

A system and method for operating system includes a first user device, a second user device, and a first device having a controller and a first database storing a first data object of a first type of data associated therewith and a second database storing a second data object of a second type of data associated therewith different than the first type of data. The second database is accessible separately from and simultaneously with the first database. The second data object forms a second portion of a display. The controller has an application interface selecting a selected database from the first, second database or both and separately and simultaneously accessing the first and second database based on the first user input command and the second user input command to obtain stored data and separately and simultaneously communicating stored data to the first user device and to the second user device.
