International Classification:

G06Q 40/00

US Classification:

705 43

Abstract:

A system and method is provided for an ATM having a display, a logic server coupled to the display, and a memory coupled to the logic server. The logic server dynamically controls the content of screens to be displayed on the display. The memory, which is accessible to the logic server, contains a profile of at least one user. In operation, the ATM detects the swipe of a user's card and requests the profile of the user whose card was swiped from a host. The ATM then receives the user's profile and stores the user's profile in the ATM.

International Classification:

G06K009/00

US Classification:

382/100000

Abstract:

A method for decoding a message embedded in a pattern of pixels. The method includes the steps of determining the pixel values for pixels from the pattern of pixels, determining binary values from the pixel values for pixels from the pattern of pixels; and determining the embedded message from the binary values. The pixels have a range of pixel values between a maximum and a minimum. The pixels are divided into cells each having glyph cell and background pixels. The binary value of a glyph pixel is determined by the contrast the glyph pixel has with its background pixels. The method can be used to decode embedded web-site address from an image with a foreground image and the embedded web-site address.

Appl. No.:

09/849719

Inventors:

Kenneth Chang - Foster City CA, US

International Classification:

G10L021/04

US Classification:

704/503000

Abstract:

Media encoding, transmission, and playback processes and structures employ a multi-channel architecture with different audio channels corresponding to different playback rates for a presentation to be transmitted over a network. Audio frames in the various audio channels all correspond to the same amount of time in the original presentation and have frame indexes that identify in the different audio channels the frames corresponding to the same time interval in the presentation. A user can make a real-time change in playback rate causing selection of a channel corresponding to the new playback rate and a frame required for prompt and smooth transition in the playback rate of the presentation. The architecture can additionally provide channels for graphics data such as image data that are displayed according to the index of the audio, and different audio channels with the same playback rate but different compression schemes for use according to available bandwidth on the network.

International Classification:

G10L021/00

US Classification:

700/094000, 381/001000, 704/503000

Abstract:

A time scaling process for a multi-channel (e.g., stereo) audio signal uses a common time offsets for all channels and thereby avoids fluctuation in the apparent location of a sound source. In the time scaling process, common time offsets correspond to respective time intervals of the audio signal. Data for each audio channel is partitioned into frames corresponding to the time intervals, and all frames corresponding to the same interval use the same common time offset in the time scaling process. The common time offset for an interval can be derived from channel data collectively or from separate time offsets independently calculated for the separate channels. Preprocessing can calculate the common time offsets for inclusion in an augmented audio data structure that a low-processing-power presentation system uses for real-time time scaling operations.

Appl. No.:

Inventors:

Kenneth Chang - Foster City CA, US

International Classification:

G10L021/04

US Classification:

704/503000

Abstract:

Preprocessing audio data to generate parameters associated with time scaling reduces the processing power required for real-time time scaling of the audio data. An augmented audio data structure includes the audio data and the parameters. The parameters for a frame of the audio data can identify best match blocks for time scaling or represent a plot of offset versus time scale that can be interpolated to determine an offset. The real-time time scaling uses the blocks that the parameters identify instead of performing a search for the best matching blocks. The parameters can also indicate which of the frames represent silence and can be scaled differently from frames that do not represent silence.

Abstract:

A print (e.g., on paper) user interface (PUI) device for decoding an embedded message to activate a function is described. The PUI can be used for transforming an embedded message into cognizable human sensory inputs. The device includes a reader and a processor. The reader can sense light from a pattern of pixels on a printed surface and determines the pixel values of the pixels. The pattern of pixels constitutes a foreground visual image that conveys cognizable information to an observer. The primary function of the embedded message need not be to launch a Web-site but to display more information related to the cognizable information. The processor has a program of computer codes readable by the processor to recover embedded message from the pattern of pixels, the program includes codes for determining the embedded message by determining binary values based on the pixel values for pixels from the pattern of pixels and codes for performing a function according to the embedded message to result in resultant information displayable by a display suitable for human sensory reception.
