Granted: 2002-06-25
Abstract: Methods and apparatus for electronically displaying metered electrical energy are disclosed. A first processor receives voltage and current signals and determines electrical energy. The first processor generates an energy signal representative of the electrical energy determination. A second processor, connected to said first processor, receives the energy signal and generates a display signal representative of electrical energy information. A display is connected to receive the display signal and displays the electrical energy information. In a first embodiment, it is preferred for the first processor to determine units of electrical energy from the voltage and current signals and to generate an energy signal representative of the determination of such units and the rate at which the units are determined. In another embodiment, the first processor determines and displays watt units, apparent reactive energy units and the rate at which such units are determined. The display may provide energy flow direction information.

Title: System and method for allocating channel elements in a code division multiple access radio telecommunications network
Inventor: RAHMAN MOHAMED ANISUR
IPC: H04W4/90
Filed: 1998-03-31
Granted: 2005-10-04
Abstract: A method and system for allocating channel elements in a code division multiple access (CDMA) radio telecommunications network is disclosed. The method begins by a contribution assessor (79) determining a candidate set of base stations having sufficient signal strength with the entering mobile station (93) to establish a voice channel. Next, the contribution assessor measures the signal strength between each base station (83-87) of the candidate set of base stations and the operating mobile stations served by each of the base stations. The contribution assessor determines which base station of the candidate set of base stations has the weakest signal strength with one of its served operating mobile stations. Then, a load processor (81) reallocates a channel element (107) away from the mobile station (89) having the weakest signal strength to the entering mobile station (93).

Title: Mesure de la densite des formations par utilisation de neutrons pulses
Inventor: ODOM RICHARD C
IPC: G01V5/12
Filed: 1998-01-29
Granted: 2005-11-29
Abstract: La présente invention concerne un appareil qui, pour mesurer la densité d'une formation, utilise une source haute énergie de neutrons pulsés induisant des rayons gamma dans la formation, et qui utilise l'atténuation des rayons gamma produits par la diffusion inélastique des neutrons rapides pour déterminer la longueur de la diffusion gamma de la formation. L'outil de trou de forage contient la source neutronique ainsi qu'un détecteur des rayonnements dans le proche gamma et un détecteur des rayonnements dans le lointain gamma. Les détecteurs de rayonnements gamma sont situés à différentes distances de la source de neutrons rapides et sont suffisamment éloignés de la dernière source de neutrons rapides de façon à réduire sensiblement l'effet du rayonnement gamma inélastique sur le transport des neutrons rapides et la production gamma de la formation. Les événements rayonnement gamma peuvent faire l'objet de tris et de dénombrements dans des caissons à dépendance temporelle et énergétique. Cette invention présente plusieurs avantages sur le carottage rayons gamma-rayons gamma, et notamment une pénétration profonde des rayons gamma. En outre, cette invention présente des supériorités par rapport aux systèmes qui mesurent notamment la porosité liée à l'hydrogène.

Title: Method and apparatus for dynamically exchanging data among participants to a conference call
Inventor: LAM YUK-MING PETER
IPC: H04M3/56
Filed: 2000-06-01
Granted: 2004-12-07
Abstract: A media exchange monitor is disclosed that selectively (i) introduces a mixer into a two-party call when the two-party call becomes a conference call (ad-hoc conference), and (ii) removes the mixer when one or more conference call participants drop out, leaving only two participants behind. When a party to a two-party call requests to convert the call into a conference call, the packet telephony system responds to the conference call request by connecting a mixer to service the conference call between the parties. When parties drops out of a conference call, leaving only two parties behind, the mixer is removed from the conference call. In one implementation, the mixer is removed from the conference call only if the two remaining parties can exchange media directly. When the media connection among the parties must be changed to introduce or remove the mixer, the media exchange monitor achieves the desired connectivity by initially querying the parties for their capabilities. Thereafter, the media exchange monitor instructs the parties to establish a direct connection for a two-party call or to connect to the mixer for a conference call. The media exchange monitor processes the results of the capability query to select a compatible compression algorithm.

Abstract: In a mobile communications service system, various value-added services can be provided for each mobile node. A mobile node transmits a registration request to a foreign agent. The foreign agent transfers a Mobile request message to an authentication process server home agent (AAAH) through an authentication process server foreign agent (AAAF). The AAAH extracts from a service control database a service profile that identifies the value-added services to be supplied to the mobile node. The service profile is distributed to a home agent using a Home agent registration request message, and to a foreign agent using a mobile request message. The home agent and the foreign agent provide services according to the distributed service profiles.

Abstract: A disc brake assembly includes an improved pad holder for holding a brake pad in the brake assembly. The pad holder takes the form of a simple spring clip, preferably a wire form, that holds the rear surface of the pad tightly against the front surface of the piston or pistons of the associated caliper to prevent brake drag and brake rattle. The clip is simple and inexpensive to manufacture and can be easily installed without removing the disc or the caliper from the brake assembly. Indeed, the pad/pad holder subassembly can be removed from the brake assembly, without using any special tools, simply by imposing sufficient upward vertical retraction forces on the pad/pad holder subassembly to deflect the spring clip and to remove the pad holder from the pistons to which it is attached.

Filed: 2001-03-02
Granted: 2005-10-18
Abstract: The essential feature is the step of generating a controllable 'dynamic' intensity field profile with a controllable beating pattern in a multimode superposition of different modes, as e.g., a fundamental mode and a higher order mode as e,g., the TE0 mode and TE1 mode of an input wavelength entering the input site of an AWG apparatus, whereby said beating pattern is controlled in a fixed, or in variable, predetermined way, as e.g., with a fixed or a wavelength dependent power ratio and beating pattern, for improving the mode overlap in a receiver waveguide associated with an output site of said apparatus. With variable conditions, a lower number of converter units is required. In a 8:1 multiplexer, for example, there is needed just one converter unit at its output. A 1:8 demultiplexer can be obtained by solely reversing the AWG apparatus. (fig. 9)

Abstract: A dynamoelectric machine includes a stator having teeth fabricated from a non-magnetic material and containing at least one embedded conductor. The teeth are unitary with a back portion that is mounted to a stator back iron. Permeance variations induced by a stator winding mounted on the non-magnetic stator teeth are low which facilitates a reduction of motor noise. Specifically, since the non- magnetic teeth reduce production of permeance variations, changes in air gap forces between the rotor and the stator are decreased.
