System and method for collecting financial transaction data

Abstract: The present invention is a system and method for collecting transaction data. A system for collecting transaction data in accordance with the invention includes at least one transaction provider (12) which provides at least an electronic receipt of financial transactions offered by each transaction provider; at least one user device (14), in communication with each transaction provider, which provides to each transaction provider a selection by a user of the user device of an offered financial transaction and in response to receipt of an acceptance of the financial transaction recorded in the received electronic receipt; and at least one user information system (18), coupled to at least one of the at least one transaction provider or the at least one user device, which stores at least electronic receipts which are received from the at least one user device or the at least one transaction provider which are verified by the user information system to have been accepted by the user of the user device. At least one intermediate service provider (20) may be coupled to the at least one transaction provider processes information relating to the accepted financial transactions transmitted to the at least one intermediate service provider to produce processed information pertaining to the accepted financial transactions.

High-redshift quasars found in Sloan Digital Sky Survey commissioning data

Abstract: We present photometric and spectroscopic observations of 15 high-redshift quasars (z > 3.6) discovered from ~140 deg2 of five-color (u', g', r', i', and z') imaging data taken by the Sloan Digital Sky Survey (SDSS) during its commissioning phase. The quasars are selected by their distinctive colors in SDSS multicolor space. Four of the quasars have redshifts higher than 4.6 (z = 4.63, 4.75, 4.90, and 5.00, the latter being the highest redshift quasar yet known). In addition, two previously known z > 4 objects were recovered from the data. The quasars all have i* < 20 and have luminosities comparable to that of 3C 273. The spectra of the quasars have similar features (strong, broad emission lines and substantial absorption blueward of the Lyα emission line) seen in previously known high-redshift quasars. Although the photometric accuracy and image quality fail to meet the final survey requirements, our success rate for identifying high-redshift quasars (17 quasars from 27 candidates) is much higher than that of previous multicolor surveys. However, the numbers of high-redshift quasars found is in close accord with the number density inferred from previous surveys.

A method for creating a dynamic talk group

Abstract: The invention relates to dynamically creating talk groups in a communications system. A new dynamic group is created by a user who defines a group definition message in his subscriber station. This group definition message uniquely identifies the new group in the system, and can be distributed to the intended group members using the usual messaging facilities available in the specific communications system. The recipients of the group definition message can store the message in their subscriber stations for subsequent use. Thus, group creation and membership management are handled at user level without interacting with the system. The role of the system is restricted to establishing a means for communication in the group whenever there are users who have activated the group for communication.

Coding, storage and signalling of scalability information

Abstract: A method and device for encoding, decoding, storage and transmission of a scalable data stream to include layers having different coding properties. The method includes: producing one or more layers of the scalable data stream, wherein the coding properties include at least one of the following: Fine granularity scalability information; Region-of-interest scalability information; Sub-sample scalable layer information; Decoding dependency information; and Initial parameter sets, and signaling the layers with the characterized coding property such that they are readable by a decoder without the need to decode the entire layers. Also, a method of encoding, decoding, storage, and transmission of a scalable bit stream, wherein at least two scalability layers are present and each layer is characterized by a set of at least one property, such as Fine granularity scalability information; Region-of-interest scalability information; Sub-sample scalable layer information; Decoding dependency information; and Initial parameter sets, that may be different from that of the entire stream, and wherein the set of at least one property is signaled for at least one layer that is different from the entire stream, wherein signaling of the set of at least one property may be in the scalable bit stream, in a file format container containing the scalable bit stream, or in a transmission or control protocol for transmission or control of at least one layer of the scalable bit stream.

Mobile station having enhanced standby mode

Abstract: When a mobile station (10) is in a DCCH camping state it monitors its assigned page frame. After making RSSI and possibly also Bit Error Rate/Word Error Rate (BER/WER) measurements the mobile station monitors the rate of change of the RSSI. If the rate of change is small and remains so, the mobile station is assumed to be in a stationary state. After determining that it is stationary, the mobile station may give an audible alert and/or display a message to request the user to confirm that the mobile station is (and will remain) stationary. When in the stationary state the mobile station inhibits making neighbor channel measurements for DCCH reselection. The mobile station continues to monitor its assigned page frame within an assigned digital control channel and to measure its own channel RSSI and possibly also the BER/WER. If these values subsequently indicate that the mobile station is no longer stationary, the mobile station immediately resumes all neighbor channel measurements.
