Title: Wireless telecommunication system with prepaid architecture
Inventor: LABONTE SYLVAIN
IPC: G06Q20/00
Filed: 1999-07-20
Granted: 2007-04-10
Abstract: There is disclosed a prepaid system (10) and method for permitting a prepaid subscriber of the cellular wireless telecommunication system to revise call features during a call within the operators node and from roaming locations to debit the subscribers prepaid account on a real-time basis. The system includes a switching node (14) permitting (50) a call to be set up with the prepaid subscriber (16) when a prepaid service credit balance exists and terminating the call when the prepaid service credit balance is nil. The switching node continually generates (52, 54) real-time call event Data Message Handier (DMH) formatted messages related to the call made by the prepaid subscriber and forwards these call event messages to a prepaid administrative network (38). The prepaid administrative network stores (56) the prepaid service credit balance of the prepaid subscriber and generates at call set up an initial charge debiting rate (60) used during the call to reduce the prepaid service credit balance. The prepaid administrative network, in response to the real-time call event messages received from the detailed call event generation means, revises the initial charge debiting rate to generate a real-time debiting rate used during the call to reduce the prepaid service credit balance.

Abstract: A stent is positioned on an undersized mandrel and the stent is coated with an excess of a polymer and drug solution. The stent is rotated to spin off the excess of the coating. The stent is then moved into a new, clean position on the mandrel. The process is repeated a few times, after which time the coating is already dry and non-sticky. This process forms a conforming coating. Various important polymer solution parameters include viscosity, solvent evaporation rate and several others The actual type of coating polymer is not as important as how the surface of the stent is treated, according to the steps described herein.

Abstract: A MEMS (Micro Electro Mechanical System) electrostatic device operated with lower and more predictable operating voltages is provided. An electrostatic actuator, an electrostatic attenuator of electromagnetic radiation, and a method for attenuating electromagnetic radiation are provided. Improved operating voltage characteristics are achieved by defining a non increasing air gap between the substrate electrode and flexible composite electrode within the electrostatic device. A medial portion of a multilayer flexible composite overlying the electromechanical substrate is held in position regardless of the application of electrostatic force, thereby sustaining the defined air gap. The air gap is relatively constant in separation from the underlying microelectronic surface when the medial portion is cantilevered in one embodiment. A further embodiment provides an air gap that decreases to zero when the medial portion approaches and contacts the underlying microelectronic surface. A moveable distal portion of the flexible composite is biased to curl naturally due to differences in thermal coefficients of expansion between the component layers. In response to electrostatic forces, the distal portion moves and thereby alters the distance separating the flexible composite from the underlaying microelectronic surface. Structures and techniques for controlling bias in the medial portion and the resulting air gap are provided. The electrostatic device may be disposed to selectively clear or intercept the path of electromagnetic radiation. Materials used in the attenuator can be selected to pass, reflect, or absorb various types of electromagnetic radiation. A plurality of electromagnetic attenuators may be disposed in an array and selectively activated in subsets.

Abstract: The invention provides a blast compression wave absorbing device, comprising means for generation of a negative pressure wave and positioned close to the facility or structure being protected {in atmosphere or under water). The device comprises at least one container having an interior filled with a gas or air having a pressure below ambient pressure (under vacuum). When a blast compression wave reaches the device, in accordance with various embodiments of the invention, the container collapses, ruptures, or its interior is being connected to the environment through rupturable diaphragm or fast-actuating valve. The ambient air starts to fill the internals of the container generating a negative pressure wave, which interteres with blast compression wave and reduces the pressure and impulse affecting the facility or structure being protected. The device can be used to protect high-risk facilities (nuclear and military installations, petrochemical plants, embassies), submerged structures, or to protect personnel in tunnels and bunkers from shock waves of fuel-air explosives.

Title: Integrated beamforming/rake/mud cdma receiver architecture
Inventor: BIERLY SCOTT
IPC: H04K1/00
Filed: 2001-02-09
Granted: 2010-06-29
Abstract: A spread-spectrum demodulator architecture (10) is presented which utilizes parallel (Fig. 1) processing to accomplish rapid signal acquisition with simultaneous tracking of multiple channels, while implementing an integrated multi-element adaptive beamformer, Rake combiner, and multi-user detector (MUD). A matched filter computational architecture is utilized, in which common digital arithmetic elements are used for both acquisition and tracking purposes. As each channel is sequentially acquired by the parallel matched filter, a subset of the arithmetic elements are then dedicated to the subsequent tracking of that channel. Additionally, multiple data inputs and delay lines are present, connecting the sampled baseband data streams of numerous RF bands and antenna elements with the arithmetic elements. The matched filter/despreader processing is virtually independent of channel origin or utilization; e.g., CDMA users, RF bands, beamformer elements, or Rake Fingers. Integration of the beamformer weighting computation with the demodulator results in substantial savings by sharing the existing circuitry performing carrier tracking and AGC. An optimal demodulator solution can be achieved through unified "space/time" processing, by providing all observables (element snapshots, Rake Fingers, carrier/symbol SNR/phase, etc.), for multiple channels, to a single adaptive algorithm processor that can beamform, Rake, and perform joint detection (MUD).
