Filed:

Nov 27, 1995

Appl. No.:

8/563033

Inventors:

Xiao Ping Hu - Mountain View CA

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 1300

US Classification:

345524

Abstract:

An image alpha blending method utilizing a parallel processor is provided. The computer-implemented method includes the steps of loading unaligned multiple word components into a processor in one machine instruction, each word component associated with a pixel of an image; alpha blending the multiple word components of different source images and a control image in parallel; and storing the alpha blended multiple word components of a destination image into memory in parallel.

Abstract:

An optical module includes an enclosure and an optical output assembly mounted on the enclosure. An emitter mounted in the enclosure is configured to emit a beam of light toward the optical output assembly. A connector, which includes two conductive layers separated by a dielectric layer, has a first side connected to the enclosure and a second side connected to the optical output assembly. An electrical trace disposed on the enclosure is connected to the first side of the connector so as to define a test circuit having a capacitance. Control circuitry is coupled to sense the capacitance of the test circuit, and configured to inhibit operation of the emitter upon sensing a change in the capacitance that exceeds a predetermined threshold.

Abstract:

Systems and methods for assessing a non-accessible parameter from accessible parameters are provided. A training process produces three databases: A dynamical model database containing input/output (I/O) models relating ABP/CBFV to ICP when estimating ICP; a mapping function database containing a mapping function for each entry in the model database, providing estimated of the dissimilarity between the unknown ICP and simulated ICP using the corresponding dynamical model on a given instance of ABP/CBFV; and a query feature database of vectors extracted from an instance of ABP/CBFV. New ABP/CBFV measurements are analyzed to extract query features that are evaluated by each mapping function in the database. The output is dissimilarity metrics providing estimates of the quality of the simulated ICP using the database models for a given ABP/CBFV instance. The dissimilarity metrics are ranked to find the optimal model. The model is used to simulate ICP using the new ABP/CBFV.
