摘要： In a computerized method for messaging, a Web page includes an embedded tag specifying a message extension program. The Web page is requested from a Web server by a Web browser of a first client computer connected to the Web server computer by a communications network. The extension program corresponding to the message tag is retrieved. A multimedia message is recorded as digital signals in a file of the client computer using the extension program. The file is sent to a second client computer as an electronic mail message.

摘要： In a computerized method a continuous signal is segmented in order to determine statistically stationary units of the signal. The continuous signal is sampled at periodic intervals to produce a timed sequence of digital samples. Fixed numbers of adjacent digital samples are grouped into a plurality of disjoint sets or frames. A statistical distance between adjacent frames is determined. The adjacent sets are merged into a larger set of samples or cluster if the statistical distance is less than a predetermined threshold. In an iterative process, the statistical distance between the adjacent sets are determined, and as long as the distance is less than the predetermined threshold, the sets are iteratively merged to segment the signal into statistically stationary units.

摘要： Speech signals from speakers having known identities are used to create sets of acoustic models. The acoustic models along with their corresponding identities are stored in a memory. A plurality of sets of cohort models that characterize the speech signals are selected from the stored sets of acoustic models, and linked to the set of acoustic models of each identified speaker. During a testing session speech signals produced by an unknown speaker having a claimed identity are processed to generate processed speech signals. The processed speech signals are compared to the set of models of the claimed speaker to produce first scores. The processed speech signals are also compared to the sets cohort models to produce second scores. A subset of scores are dynamically selected from the second scores according to a predetermined criteria. The unknown speaker is validated as the claimed speaker if the difference between the first and a combination of the subset of scores is greater than a predetermined threshold value.

摘要： A pretensioned cable transmits power along a first support member (link) from a rotary actuator to a rotating output joint, typically an output pulley fixed to a second link arm but rotatable in a coupling between the first and second links. A reducer, typically two sets of coupled idler pulleys of different diameter, is mounted at a point removed from the actuator, and preferably as close as possible to the output joint. An axially split spool mounted on the actuator output wraps the outgoing and returning cable sections on different halves of the spool in opposite directions to provide pretensioning of the cable in the entire cable circuit at one point. To form a differential, a pretensioned cable carried on paired pulleys having smooth outer surfaces parallel to the axis of rotation couples the pulleys. The pulleys have axes of rotation that can intersect and their cable carrying surfaces are closely spaced, preferably by less than half the width of the cable. The outer surfaces can be stepped to accommodate two or more cables for bi-directional operation, or to create a conventional differential with a spider. The links and pulleys of the transmission are long and narrow. This high aspect ratio provides a compact configuration that is conducive to whole arm manipulations where any exterior surface of the links can engage an object. A low inertia, low friction brushless D.C. motor operating under the control of a pulse width modulated controller responsive to the current drawn by the motor, in combination with the cable transmission of this invention, provide excellent force control.

摘要： In a computerized method for processing speech signals, first vectors representing clean speech signals are stored in a vector codebook. Second vectors are determined from dirty speech signals. Noise and distortion parameters are estimated from the second vectors. Third vectors are predicated, based on estimated noise and distortion parameters. The third vectors are used to correct the first vectors. The third vectors can then be applied to the second vectors to produce corrected vectors. The corrected vectors and the first vectors can be compared to identify first vectors which resemble the corrected vectors.

摘要： A technique for accessing an item of interest within a particular one of a plurality of stored representations of data is disclosed. In one embodiment, the technique is realized by having a processing device searching a plurality of stored annotations corresponding to different items within the plurality of stored representations to locate an annotation of interest corresponding to the item of interest. The annotation of interest has an associated search identifier and an associated location identifier corresponding to a location of interest within the particular one of the plurality of stored representations. The processing device then searches a plurality of stored search identifiers associated with the plurality of stored annotations to locate the search identifier and an address identifier corresponding to a location of the particular one of the plurality of stored representations within the plurality of stored representations. The processing device then accesses the item of interest at the location of interest using the address identifier and the location identifier.
