Abstract: A failsafe configuration for alternative network telephony is disclosed. An indication as to whether an alternative network telephony call processing system is available to process calls from an associated piece of telephone equipment is received automatically and transparently to a user of the telephone equipment. Calls placed from the telephone equipment at a time when the alternative network telephony call processing system is available to process calls are processed via alternative network telephony. Calls placed from the telephone equipment at a time when the alternative network telephony call processing system is not available to process calls are processed via the public switched telephone network (PSTN).

Abstract: The invention enables a recorder to mark a recording as an event is being recorded. The invention can enable the specification of a mark so that the mark is associated with recording data obtained at a time other than the time at which the mark is specified (“non-contemporaneous marking”), i.e., prior to the time of the mark (“retrospective marking”) or after the time of the mark (“predictive marking”). The invention can also enable the use of multiple types of marks, each type of mark having a particular meaning. Additionally, the invention can enable marking capability to be implemented so that specification of a mark causes predetermined operation of the recording unit in accordance with the type of the mark (“augmented marking”).

Abstract: A system and method are disclosed for multicasting information to a set of clients that includes transmitting the information to a primary client from a server and instructing the primary client to forward the information to a secondary client.

Abstract: A pushbutton user interface enables a user to preview the effect of activating a pushbutton of the interface before the pushbutton is activated. The pushbutton user interface can be implemented so that an input (preview input) to the pushbutton that does not produce an activation of the pushbutton is sensed and, in response to the sensed input, a preview is displayed that indicates the effect of activating the pushbutton. The preview input can be sensed using, for example, a force-sensitive resistor, potentiometer or strain gauge. The preview display can include, for example, a visual display, an audio display, a haptic display, or a combination of two or three such displays. The pushbutton user interface can be implemented so that the preview input and an activation input (i.e., an input that produces an activation of the pushbutton) are sensed as a result of an input to the pushbutton along the same axis or along different (e.g., orthogonal) axes.

Abstract: A system and method for providing interaction between a user and a computer system is disclosed. A computer system has a sensor configured to read and interpret a content hotspot and to read and interpret a context hotspot, and a processor configured to perform an operation that is based on content information interpreted from the content hotspot. The operation is influenced by context information interpreted from the context hotspot.

Abstract: Dense range data obtained at real-time rates is employed to estimate the pose of an articulated figure. In one approach, the range data is used in combination with a model of connected patches. Each patch is the planar convex hull of two circles, and a recursive procedure is carried out to determine an estimate of pose which most closely correlates to the range data. In another aspect of the invention, the dense range data is used in conjunction with image intensity information to improve pose tracking performance. The range information is used to determine the shape of an object, rather than assume a generic model or estimate structure from motion. In this aspect of the invention, a depth constraint equation, which is a counterpart to the classic brightness change constraint equation, is employed. Both constraints are used to jointly solve for motion estimates.

Abstract: A stream of time-ordered data, such as a movie, is divided into multiple fragments of equal length, which are repetitively transmitted at different respective repetition rates. The fragments are reordered for transmission so that those which occur near the beginning of the original data stream are transmitted more frequently than those which occur later in the data stream. When a user enters a request to utilize the data, the individual fragments are stored upon receipt at the user's premises, and reassembled into a contiguous stream. The ordering of the fragments is such that the wait time required before utilization of the data can begin is limited to a predetermined maximum, and at least one copy of every fragment becomes available by the time it is needed.

Abstract: A data-compressed audio waveform is temporally modified without requiring complete decompression of the audio signal. Packets of compressed audio data are first unpacked, to remove scaling that was applied in the formation of the packets. The unpacked data is then temporally modified, using one of a number of different approaches. This modification takes place while the audio information remains in a data-compressed format. New packets are then assembled from the modified data, to produce a data-compressed output stream that can be subsequently processed in a conventional manner to reproduce the desired sound. The assembly of the new packets employs a technique for inferring an auditory model from the original packets, to requantize the data in the output packets.

Abstract: Decompressing compressed video information using relatively less temporary storage is disclosed. A compressed bit stream of video information including a compressed portion is received. A reverse combination in the transform domain is performed on the compressed portion to produce two corresponding portions of video information, where the two portions represent the compressed portion in a less compressed form. The two portions of video information are temporarily stored as a reverse combination is being performed. One of said two portions of video information is transformed, decoded, and decompressed to produce a decompressed portion of video information. The decompressed portion of video information is output.

Abstract: A user can selectively engage some part or all of the haptic display of a haptic interface device to produce an enhanced interaction with an environment with which the user interacts using the haptic interface device. Further, the haptic interface device can be implemented so that the part of the haptic display that is engaged can be engaged to varying degree. The degree of engagement with the haptic display (together with whether part or all of the haptic display is engaged) determines the manner in which the haptic display is experienced by the user. The selective engagement with the haptic display is enabled by adding a haptic clutch model to the underlying haptic model used to produce the haptic display, the haptic clutch model engaging some part or all of the haptic model in response to user input. The addition of a haptic clutch model to the haptic model used to produce a haptic display provides a richer user interaction than is provided by a haptic display produced by the haptic model alone.

Abstract: The invention facilitates browsing of an indexed collection of electronic content by displaying information identifying a current location within the collection of electronic content using a non-visual display (e.g., audio display and/or haptic display). The information identifying the current location can be displayed with variable resolution and the content of the display of the information identifying the current location can be dependent on the resolution. The invention can be used to browse any type of electronic content, including, for example, audio content, visual content, text content or some combination of such content. The invention can be used to browse electronic content that is indexed in any way, such as, for example, electronic content that is indexed (partly or entirely) alphabetically, numerically or by date.

Abstract: Encoding/decoding a stream of bits is disclosed. An encoding unit uses a modified Z-coder to code the zero/non-zero significance function and Huffman coding for the non-zero coefficients themselves. The encoding unit includes a significance function generator that receives coefficients and outputs a single significance bit. A zero coefficient eliminator receives coefficients in parallel with the significance function generator and outputs coefficients if non-zero. Output from the significance function generator is coded using the modified Z-coder. Output from the zero coefficient eliminator is coded using Huffman coding. Both outputs are combined to form the resulting compressed stream. The modified Z-coder is similar to a standard Z-coder but uses a different technique for the LPS (least probable symbol) case during encoding and decoding that results in a Z-coder that functions appropriately.

Abstract: The estimation of an HRTF for a given individual is accomplished by means of a coupled model, which identifies the dependencies between one or more images of readily observable characteristics of an individual, and the HRTF that is applicable to that individual. Since the HRTF is highly influenced by the shape of the listener's outer ear, as well as the shape of the listener's head, images of a listener which provides this type of information are preferably applied as an input to the coupled model. In addition, dimensional measurements of the listener can be applied to the model. In return, the model provides an estimate of the HRTF for the observed characteristics of the listener.

Abstract: Identification of starting and ending times of commercial breaks and commercials within those commercial breaks found in audiovisual content is disclosed. A solution to a “batch optimization” problem is used in which commercial locations within a set of audiovisual content are detected as a group by choosing a set of commercial locations which optimizes a cost function which can include considerations of, for example, 1) one or more cues, 2) relative locations of commercials within the audiovisual content, and/or 3) probability models based on statistics obtained regarding characteristics of typical commercial and commercial breaks. Optimization can be done over the total set of commercial location decisions, rather than on a per-commercial basis. Additionally, the cost function can be iteratively evaluated and many more types of cues and combinations of cues can be used in detection of commercials.

Abstract: Providing interaction between a user with remote data stored on a network is disclosed. A physical medium has at least one hot spot encoded with linking data enabling access to remote data. The linking data is encoded according to a spectral encoding scheme. At least part of the linking data is visible and is blended with and appears to comprise at least part of an un-encoded graphic or text visible on the physical medium such that it is not apparent to a viewer of the physical medium that said linking data is encoded in said at least one hot spot. A sensor measures the hot spot and decodes the linking data. A transmitter coupled to the sensor transmits the linking data to a remote computer system. The remote computer system responds to the linking data to retrieve the remote data and present the remote data to the user.

Abstract: A precision motion platform carrying an imaging device under a large-field-coverage lens enables capture of high resolution imagery over the full field in an instantaneous telephoto mode and wide-angle coverage through temporal integration. The device permits automated tracking and scanning without movement of a camera body or lens. Coupled use of two or more devices enables automated range computation without the need for subsequent epipolar rectification. The imager motion enables sample integration for resolution enhancement. The control methods for imager positioning enable decreasing the blur caused by both the motion of the moving imager or the motion of an object's image that the imager is intended to capture.
