Granted: 2006-01-03
Abstract: Methods and apparatus for wireless communication in systems such as omni-beam and narrow-beam fixed wireless loop (FWL) systems. In a first technique in accordance with the invention, referred to as code division duplex (CDD) time-slotted CDMA, uplink and downlink portions of the system are separated using code division duplexing, while the users within a given cell are also separated using codes, e.g., using time- slotted CDMA. In a second technique in accordance with the invention, referred to as time division duplex (TDD) time-slotted CDMA, uplink and downlink portions of the system are separated using time division duplexing, e.g., time slots, while the users in a given cell are separated using codes, e.g., time-slotted CDMA. Both the CDD and TDD techniques may make use of an electronically-steered beam which is designed to provide simultaneous coverage within a given cell for two or more users separated by codes. In a third technique in accordance with the invention, referred to as orthogonal frequency division multiplexing (OFDM), uplink and downlink portions of the system are separated in frequency, while the users are, e.g., also separated in frequency.

Abstract: A telephone line-powered power supply, a method of operating the same and telephone line-powered ancillary equipment. In one embodiment, the power supply includes: (1) a transformer having a primary winding and a secondary winding and (2) an energy storage device (which may, but is not required to, be a capacitor) series-coupled to the primary winding, the primary winding and the energy storage device adapted to be coupled to, and provide a terminating resistance for, a telephone line. A node between the primary winding and the energy storage device provides DC power.      Another embodiment employs a control switch to regulate an energy storage device, thereby dispensing with a need for the transformer.

Abstract: L'invention concerne un procédé d'usinage de pièces par enlèvement de matière, à l'aide d'un outil qui est guidé au-dessus de la pièce à usiner, dans des voies de passage. A cet effet, dans chacun des points, l'angle de pivotement et de piqué de l'outil est choisi de manière à optimiser la largeur d'une zone de tolérance dans laquelle se situe la zone active (K) de l'outil dans une zone de tolérance de la surface théorique (Psi) voulue de la pièce. A cette fin, l'écart entre les deux points (Pl, Pr) qui caractérisent les points les plus extérieurs de la zone de tolérance, est maximisé. Ce procédé permet de produire des surfaces de grande précision avec un nombre réduit de voies de passage.

Granted: 2002-04-30
Abstract: A data processing system uses a plurality of individual code segments, forming unique and autonomous tools, which are bound into a complete executable process only at the time of loading or executing the process. This enables process code to be short and the required tools to be brought into and out of local memory only when required.      The system may have an interconnected array of processor nodes and allocates processes in a parallel fashion between nodes automatically and transparently to the user, ensuring that the most efficient use is made of the processing power available. Tools are stored in a virtual code that enables portability between different hardware architectures.

Abstract: A pharmaceutical dosage form such as a capsule capable of delivering therapeutic agents into the body in a time--controlled or position-controlled pulsatile release fashion, is composed of a multitude of multicoated particulates (beads, pellets, granules, etc.) made of one or more populations of beads. Each of these beads except an immediate release bead has at least two coated membrane barriers. One of the membrane barriers is composed of an enteric polymer while the second membrane barrier is composed of a mixture of water insoluble polymer and an enteric polymer.  The composition and the thickness of the polymeric membrane barriers determine the lag time and duration of drug release from each of the bead populations. Optionally, an organic acid containing intermediate membrane may be applied for further modifying the lag time and/or the duration of drug release. The pulsatile delivery may comprise one or more pulses to provide a plasma concentration-time profile for a therapeutic agent, predicted based on both its pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.
