Title: System for switching base stations in mobile communications
Inventor: WATANABE MASATOSHI
IPC: H04W36/08
Filed: 1997-09-19
Granted: 2004-11-30
Abstract: A CDMA/TDD type radiocommunication system and a method therefor. At the time of switching the base station of a communication partner in accordance with movement, a moving station monitors the received electric power of data, as received from a peripheral base station, by a received power detector ( l2). When the received power from a base station other than the main one in communication exceeds a preset value, the base station is employed as a follower one to transmit the same data as those of the main base station so that the data from the main and the follower base stations are simultaneously received by a correlator (5) and a correlator (6). When the received power of the follower base station then exceeds that of the main one, the moving station switches the main base station to the follower base station and transmits the data to a new base station.

Abstract: A solid burnable fuel composition which contains a major proportion of spent dried coffee grounds is described. The fuel composition includes at least 50% dried spent coffee grounds and a combustible wax which are mixed together and compressed into a suitable shape for combustion. The fuel composition may further include a small amount, 10% or less, of a coking agent useful to control burn rate and to prevent cracking of compressed fuel during combustion. Small amounts of cellulosic material may also be incorporated to improve the structural properties of the composition. Due to its superior heat and flame production, dried spent coffee grounds are an excellent fuel source for processed fuel products such as fire-logs and fuel pellets. The advantage is a hotter, cleaner burn which produces less soot and smoke, releases fewer harmful pollutants and provides a brighter flame over a longer period of time.

Abstract: The present invention relates to glial cell line-derived neurotrophic factor (GDNF), a potent neurotrophin that exhibits a broad spectrum of biological activities on a variety of cell types from both the central and peripheral nervous systems. The present invention involves the cloning and characterization of receptors for GDNF. Nucleic acid and amino acid sequences are described for GDNFR protein products. A hydrophobic domain with the features of a signal peptide is found at the amino terminus, while a second hydrophobic domain at the carboxy terminus is involved in the linkage of the receptor to the cell membrane. The lack of a transmembrane domain and cytoplasmic region indicates that GDNFR requires one or more accessory molecules in order to mediate transmenbrane signaling. GDNFR mRNA is widely distributed in both nervous system and non-neural tissues, consistent with the similar distribution found for GDNF.

Title: Secure distribution of digital representations
Inventor: ZHAO JIAN
IPC: G09C5/00
Filed: 1999-02-09
Granted: 2011-05-03
Abstract: Techniques for secure distribution of digital representations that combine encryption and watermarking. When a user at a client desires to download a digital representation, the user makes a request to a server for the digital representation, which encrypts the digital representation using a first key and downloads the encrypted digital representation to the user. Before the user performs any operation on the decrypted digital representation, a secret fingerprint watermark identifying the user is added to the digital representation. The fingerprint watermark is added either at the server or at the client and a copy of the fingerprinted digital representation is kept at the server. If the user makes an impermissible use of the digital representation, the secret fingerprint watermark can be used to identify the user. The request made by the user indicates the type of use that the user whished to make of the digital representation. If the use involves storage of the digital representation at the client, the server provides a second key that the client employs to encrypt the digital representation. If the user has permission to do so, the user may modify the digital representation and return the modified digital representation to the server for further distribution. In this case, the second key is used to encrypt the digital representation when it is sent to the server. The second key also serves as the user identification in the fingerprint watermark. If the user loses the second key, it can be recovered from the copy of the fingerprinted digital representation kept at the server. The first and second keys and any decrypted copy of the digital representation are kept in secure storage in the client.

Title: Low complexity decision feedback sequence estimation
Inventor: JAVERBRING STEFAN
IPC: H03M13/00
Filed: 1999-08-17
Granted: 2008-01-15
Abstract: A Decision Feedback Sequence Estimator (DFSE) metric is determined by storing one or more tables of Decision Feedback Estimation (DFE) hypotheses in a memory, and then using values of the DFE hypotheses that are retrieved from storage to determine the DFSE metric. The DFE hypotheses may be precalculated and stored into the memory prior to performance of any retrieval operation. Alternatively, the table may start out empty, and the DFE hypotheses may be determined as needed for a particular DFSE  metric computation. The determined DFE metric may then be stored into a table for later retrieval if the metric is needed again. The DFE hypotheses may be stored into a single table or, to reduce memory requirements and computational complexity, may be stored into corresponding ones of plural tables. MLSE hypotheses, which are also used in the DFSE metric determination, may similarly be stored into one or more tables for later retrieval as needed.

Abstract: A first telecommunications system (20 1), with radio trans-mission access utilizing code division multiple access (CDMA) with a time division multiple access (TDMA) component, has at least partially geographically overlapping coverage with a sec-ond telecommunications system (20 2), base station (BS) of the first system communicates over an air interface with a subscriber station (SS) and broadcasts a common broadcast physical chan-nel (BPCH) including broadcast system identity information on at least an active carrier/timeslot combination (C/TS). The sub-scriber station uses the broadcast system identity information to distinguish between transmissions of the two telecommunica-tions systems, and for framing transmissions in the first system.  The base station of the first system broadcasts at least two com-mon broadcast physical channels active on different timeslots.  Preferably, a fixed direct sequence CDMA code is employed for the common broadcast physical channel. In accordance with an instant dynamic channel selection procedure of the present invention, the subscriber station selects a carrier/timeslot for sending an access request to the first system base station. The carrier/timeslot selected is also used for a traffic channel and is preferably a least interfered carrier/timeslot. In response to the access request, the first system base station sends an answer on a next down-link carrier/timeslot included in a duplex pair with the selected carrier/timeslot. At any given moment a connection between the first system base station and the subscriber station is borne on a physical channel of the first telecommunications system, the physical channel being defined by a code, timeslot, and frequency.

Abstract: The present invention coordinates paging, network restriction, and other network-based communications (e.g., mobile measurement requests for O & M) in a mobile telecommunications network. Paging messages, network messages, and other messages may be consolidated in one message so that the mobile need only power up once to retrieve the various information provided in the one message. In one example, non-limiting embodiment, paging groups of mobile stations and network access restriction group of mobile stations are merged into a single set of paging and network access restriction groups to which different mobile stations belong. A mobile station therefore need only process one message in order to be informed about paging and network access restriction information pertinent to that mobile station. In the example mobile groups embodiment, that one message corresponds to its consolidated paging and network access group, and the single paging and network access group message is transmitted during a specified time interval associated with the group. As a result, an idle mobile station belonging to that group need only leave a power savings sleep mode to receive that message during the specified group time interval.  Otherwise, the idle mobile station can return to the power savings sleep mode to conserve its battery life.
