Abstract: A system for playing card games remotely includes both a multimedia communication system that allows players located remotely from each other to seeand hear each other, and a "card toaster" and associated image recognition system at each game site which receives and manages a physical deck of cards at every site at which the game is being played. The toaster has the capability of (1) reading cards, for example, by scanning them, (2) finding particular cards, and, if necessary, sorting them, and (3) distributing cards, such as by dealing them. The system enables the players to deal and then play a game, such as the game of bridge, in a manner which closely approximates the manner in which a game is played when all players are co-located. Thus, once play is started, the image recognition system reads the cards played on a table at any site, and transmits information regarding those cards to the other sites. At the other sites, the card toaster is signaled and arranged to distribute the same cards, face up on the table. (Fig. 1)

Granted: 2000-11-07
Abstract: A private base station location register supports the registering of multiple mobile stations at a private base station and provides control information for enabling a personalized call delivery feature at the private base station for each registered mobile station. When registration of a mobile station with a private base station is performed, the private base station location register receives mobile station information from a private base station along with assignment of a local unique address for each one of the multiple mobile stations registering with the private base station. When the private base station receives an incoming call for a particular one of the mobile stations, this local unique address associated with the particular station is provided by the base station location register as part of the incoming call information also received by the base station thereby allowing the base station to distinctively alert the particular mobile station. By receiving a local unique address for each of the mobile stations from the base station location register, the private base station is also able to advantageously offer various intelligent features which are personalized according to customer needs. For example, a calling party may have his or her name displayed on the reached mobile station for the convenience of the user at this mobile station.

Title: Network-based migrating user agents for personal communication services
Inventor: LAPORTA THOMAS F
IPC: H04L29/06
Filed: 1996-06-18
Granted: 2000-11-14
Abstract: The present invention is a user process that resides in network nodes to act as an agent for the mobile terminals in PCS environments. The user process handles all negotiation and complex signaling functions for the user, thus reducing the amount of signaling traffic that must travel over the valuable air interface. To achieve low call establishment times the user process is migrated as users move. Three embodiments of mechanisms for migrating the user process are disclosed. The NAIVE approach enables the amount of data size to be transferred to be optimized, leading to low overhead. This approach also provides flexibility when migrating across heterogeneous environments. A second alternative, termed the TERN approach, is promising for cases when the program is compute intensive and asynchronous migration is essential. The last approach considered, Condor, provides high reliability in the form of checkpointing, but incurs a high migration delay and has high memory requirements for the network processors.

Abstract: A flotation control system for controlling the boom of a tractor or brush cutting machine. Three hydraulic valves operate together and work in conjunction with the existing main valve of the tractor or brush cutting machine to provide flotation control or automatic movement up and down of the boom in response to ground surface variations. The system also allows the amount of weight that the cutter or other attachment exerts against the ground to be increased or decreased. The first valve is a flow control valve or a flow restricting or dividing valve that divides hydraulic flow from the pump of the tractor to the flotation control system. The second valve is a pressure reducing valve that provides the general operation of the flotation control system. The third valve is a directional valve and functions as an on/off for the flotation control system. The third valve allows a float mode by moving a cylinder which is already present in the tractor hydraulic system up or down to control movement of the boom up or down. The system is used in either a closed center or open center hydraulic system. A method of providing flotation control for controlling the boom of a tractor or brush cutting machine is also disclosed.

IPC: H04B10/08
Filed: 1995-04-24
Granted: 2006-11-28
Abstract: An air bubble in the core of an optical fibre constitutes a broad band reflector to light waves propagated in the fibre. A fibre end is first stripped and cut in the conventional way, after which in the end surface, a pit in the core region is produced by etching. The fibre end is therefore treated with e.g. diluted hydrofluoric acid, that etches the higher doped core more rapidly than the cladding.      The etched fibre end is then welded to a standard fibre so that a splice is obtained where the desired air bubble is enclosed in the fibre core. The magnitude of the reflectance of the produced reflector can then be changed by repeated heating steps, in the same way as in welding of the splice and/or by filling the bubble with another medium than air or by a coating one of its walls with a suitable material, e.g. a metal.

Title: Method, apparatus, and radio for optimizing hidden markov model speech recognition
Inventor: KUSHNER WILLIAM M
IPC: G10L15/14
Filed: 1996-01-29
Granted: 2001-04-10
Abstract: In a statistical based speech recognition system, one of the key issues is the selection of the Hidden Markov Model that best matches a given sequence of feature observations. The problem is usually addressed by the calculation of the maximum likelihood, ML, state sequence by means of a Viterbi or other decoder. Noise or inadequate training can produce an ML sequence associated with a Hidden Markov Model other than the correct model. The method of the present invention provides improved robustness by combining the standard ML state sequence score (416) with an additional path core (418) derived from the dynamics of the ML score as a function of time. These two scores, when combined, form a hybrid metric (420) that, when used with the decoder, optimizes selection of the correct Hidden Markov Model (422).
