Abstract: An apparatus for and method of implementing a novel buffer based full duplex communication system is disclosed. The disclosed invention is particularly useful in native signal processing systems wherein heavy contention of processor resources typically exist, such as in systems running multi-tasking operating systems. The communication system of the present invention includes a receiver, transmitter, echo canceler, CODEC and telephone hybrid. The major components of the system operate on a buffer of input samples consisting of a set of input bits. The communication system operates to generate a buffer of output samples consisting of a set of output bits. The invention utilizes a novel buffer switching mechanism to optimize the tradeoff between processing response time, on one hand, and robustness to interrupt latency and processor implementation on the other hand.

Abstract: A high-precision multi-channel blending operation replaces a single pass blending operation to overcome distortions resulting from an insufficient number of bits available per pixel in a hardware frame buffer. A desired frame buffer configuration, with a fewer number of channels, and a larger number of bits available per channel than available for a single pass blending operation, is specified and allocated in memory. The same, fewer number of channels from a destination image are written into the frame buffer. The frame buffer is configured for blending, and the same, fewer number of channels from the source image are blended into the frame buffer. The contents of the frame buffer is written into a memory location. The above steps are repeated, until all of the channels have been blended and written into different parts of memory. The channel information from the memory locations are combined to form an image having a user-desired bit resolution.

Abstract: A snap-on hinge assembly (20) for pivotally mounting a door (14) to a base (12) including a pivot saddle or pin (22) and a snap-acting gripping assembly (24) formed to slidably mount over, and resiliently snap into gripping engagement with, pivot pin 22. The gripping assembly (24) and pivot pin (22) are formed for pivoting of the gripping assembly (24) around the pivot pin (22) while in gripping engagement therewith, and the hinge assembly (20) further is formed with over-travel stopping surfaces (15, 38) positioned so that reaction forces between the door (14) and the base (12), upon relative engagement in an open position, urge the gripping assembly (24) and the pivot pin (22) in a direction preventing unsnapping of the gripping assembly (24) from the pivot pin (22).

Abstract: Document information is encoded in a graphic symbol applied to the document. The symbol is read to retrieve the document information which is then translated into a humanly discernible form different from that appearing on the document. In one embodiment of the invention, a symbol is applied to sheet music and encoded with the music score printed thereon. The symbol can then be read to produce an audio rendition of the music score. Also, a symbol can be applied to a printed text page and text encoded. The symbol can then be read to produce a vocal reading of the text. Other applications using encoded symbols to uniquely identify or memorialize persons named on credit cards and business cards are disclosed.

Abstract: A pump includes a coaxially integrated pump bypass/relief valve element of high density polymer material seats against a hard metallic sleeve that is pressed into a first counterbore around the bypass flow channel with an interference fit. That axial end of the sleeve bearing the valve seat face projects, for a substantial proportion of the sleeve length, beyond the first counterbore shoulder into a second counterbore space to provide an annular space around the outside diameter surface of the sleeve to free the seat face end of the sleeve from direct structural restraint.

Abstract: A current mode of operation is provided to a Walsh spreader (203), and based on the current mode of operation, the Walsh spreader (203) either varies a Walsh code at a symbol rate, or holds the Walsh code constant. During multi-carrier transmission a first symbol within a data stream (210) is spread with a first Walsh code, while symbols immediately preceding and following the first symbol are spread by a another, differing Walsh code. The sequence of Walsh codes exiting the spreader (201) is further scrambled by a pair of Pseudo-Noise (PN) codes (224) that are held constant for three Walsh code periods during multi-carrier transmission, and are not held constant during direct-spread transmission.

The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles.

Abstract: A transmitter (300) comprises summers (301-307, 3178-319), and mixers (309-315, 333). During multi-carrier transmission, multiple I and Q components enter the transmitter. I.sub.1 is summed with I.sub.3, Q.sub.3 is subtracted from Q.sub.1, Q.sub.1 is added to Q.sub.3, and I.sub.3 is subtracted from I.sub.1. The outputs of a first and a second summer (301, 305) enters a first and a second mixer (309, 313) where they are mixed by a cosine function. Similarly, the outputs of a third and a fourth summer (303, 307) enter a third and a fourth mixer (311, 315) where they are mixed by a sine function. The output from first and the second mixer (309, 311) enter a first summer (317) where they are summed along with the I.sub.2 component. The output from the third and the fourth mixer (313, 315) enters a second summer (319) where they are summed along with the Q.sub.2 component.

Abstract: A computer system provides a graphical user interface (GUI) to assist a user in completing electronic forms. The computer includes components such as a processor, user interface, and video display. Using the video display, the processor presents a row entry template including a menu field and an associated data field. The user completes the menu field by selecting a desired menu entry from a list of predefined menu entries. The user completes the data field by entering data into the data field. This format is especially useful when the data entry provides data categorized by the menu entry, explains the menu entry, or otherwise pertains to the menu entry. Each time the GUI detects activation of a form expand key, it presents an additional row entry template for completion by the user. Upon selection of a submit key, data of the completed form is sent to a predefined destination, such as a linked list, table, database, or another computer.

Abstract: Optical media is imaged by a combination of components for splitting a coherent beam into two co-propagating optical beams; converging the optical beams to produce a pattern of interference fringes having a pitch; varying the pitch and/or amplitude of the interference pattern fringes; axially rotating the fringes around the media; and axially rotating the co-propagating optical beams so as to maintain rotary synchronism with the axially rotating fringes as the permanent fringes are formed in the media whereby the longitudinal index of refraction is modulated along the media preferably with circular symmetry. The media is positioned as a work piece along a workpiece axis, with some of the system components translated along and/or rotated about the workpiece axis. Independently variable design parameters can, according to the preferred control system, be specified in advance with a high degree of flexibility.
