Abstract: A method and apparatus for antenna switching, grouping, and channel assignments in wireless communication systems. The invention allows multiuser diversity to be exploited with simple antenna operations, therefore increasing the capacity and performance of wireless communications systems. Channel characteristics indicative of signal reception quality for downlink or bi-directional traffic for each channel/antenna resource combination are measured or estimated at a subscriber. Corresponding channel characteristic information is returned to the base station. Channel characteristics information may also be measured or estimated for uplink or bi~directional signals received at each of multiple receive antenna resources. The base station employs channel allocation logic to assign uplink, downlink and/or bi-directional channels for multiple subscribers based on channel characteristics measured and/or estimated for the uplink, downlink and/or bi-directional channels.

Abstract: A chromatography cartridge with a packed bed is manufactured from an inner and outer chamber (11), the inner chamber being in an insert (12) that is slidable into the outer chamber (11) with openings in each such that a slurry that is originally placed in the interior of the outer chamber (11) as the parts are being pressed into each other. During the assembly, the particles in the slurry are compressed to fill the smaller volume of the inner chamber and excess liquid is discharged through ports in both chambers. The construction allows for a highly precise and reproducible column filling process with a minimum of steps and operator intervention and thereby low cost and reduced error.

Abstract: A patient is provided with an increased sense of satiety by increasing resistance to the outflow of food from the stomach and through the intestines.  Stomach emptying may be slowed with devices implantable within the gastrointestinal tract below the stomach. Implants are preferably removable and can include artificial strictures that may be adjustable to vary the rate of stomach emptying. Slowing gastric emptying may induce satiety for a longer period and may therefore reduce food consumption. Many of the embodiments include intestinal liners or sleeves, but they need not. The resistor concept may be applied to a simple anchor and resistor without a long liner.

Abstract: An annuloplasty repair segment and template for heart valve annulus repair. The elongate flexible template may form a distal part of a holder that also has a proximal handle. Alternatively, the template may be releasably attached to a mandrel that slides within a delivery sheath. the template being released from the end of the sheath to enable manipulation by a surgeon. A tether connecting the template and mandrel may also be provided. The template may be elastic, temperature responsive, or multiple linked segments. The template may he aligned with the handle and form a two- or three-dimensional curve out of alignment with the handle such that the annuloplasty repair segment attached thereto conforms to the curve. The template may be actively or passively converted between its straight and curved positions. The combined holder and ring is especially suited for minimally-invasive surgeries in which the combination is delivered to an implantation site through a small access incision with or without a cannula, or through a catheter passed though the patient's vasculature.

Title: Banknotes with a printed security image that can be detected with one-dimensional signal processing
Inventor: JORDAN FRED
IPC: G06T1/00
Filed: 2005-10-12
Granted: 2014-12-02
Abstract: The present invention aims to propose a method to generate a security pattern to be embedded in an original image having the particularity that the detection of the security pattern can be achieved through a simple, low processing capability device. The present invention proposes a method for generating a security image comprising an original image and a security pattern, characterized in that the security pattern has the form of a grating in which the lines width and/or the line spacing is modulated to embody a predefined data, the security image is generated by the modulation of at least one color of at least a part of the original image with the grating. The present invention belongs to the fields of security printing and copy protection of banknotes. It aims at preventing illegal copy and duplication of banknotes by printing a security image on the banknote. A device capable of detecting this security image with one-dimensional signal processing is described. Acquisition and printing devices that contain this detector can perform a quick, on-the-fly analysis of the images that transit through them during their normal course of operations, and refuse to perform their function on an image if it contains the security image. This analysis is fast enough relatively to the normal operation of the device so as to go unnoticed by the user. The security image is incorporated by a bi-level halftone image. The Fourier transform of this halftone image contains a two-dimensional pattern with a circular symmetry that is built by applying a 360-degree rotation to a one-dimensional signal. This one-dimensional signal exhibits a degree of self-similarity across a given range of scale changes. It may be detected by traversing the two-dimensional pattern along a straight line passing through its center.

Title: Method and system for coating sections of internal surfaces
Inventor: TUDHOPE ANDREW WILLIAM
IPC: F16L58/00
Filed: 2006-03-06
Granted: 2010-07-27
Abstract: A method and system for coating the internal surfaces of a localized area or section of a workpiece (10) is presented. Conductive structures (12 and 14) are inserted into one or more openings of a workpiece to define the section to be coated. In some embodiments, a bias voltage (32) is connected to a workpiece section, which functions as a cathode. A gas source (18) and vacuum source (22) are coupled to each conductive structure through a flow control system (48 and 50). The flow control system enables a first opening to function as a gas inlet and a second opening to function as a vacuum exhaust.  Only the section encompassed by the conductive structures is coated. When the coating process is completed, a means for varying the conductive structures along the length is utilized to move onto the next section to be coated.
