Abstract:
Mechanisms for interferer detection can detect interferers by detecting elevated signal amplitudes in one or more of a plurality of bins (or bands) in a frequency range between a maximum frequency (fMAX) and a minimum frequency (fMIN). To perform rapid interferer detection, the mechanisms downconvert an input signal x(t) with a local oscillator (LO) to a complex baseband signal xI(t)+jxQ(t). xI(t) and xQ(t) are then multiplied by m unique pseudorandom noise (PN) sequences (e.g., Gold sequences) gm(t) to produce m branch signals for I and m branch signals for Q. The branch signals are then low pass filtered, converted from analog to digital form, and pairwise combined by a pairwise complex combiner. Finally, a support recovery function is used to identify interferers.

Abstract:
Representing a face by jointly quantizing features and spatial location to perform implicit elastic matching between features. A plurality of the features are extracted from a face image and expanded with a corresponding spatial location in the face image. Each of the expanded features is quantized based on one or more randomized decision trees. A histogram of the quantized features is calculated to represent the face image. The histogram is compared to histograms of other face images to identify a match, or to calculate a distance metric representative of a difference between faces.
Abstract:
A method for preparing a clinical restraint for a subject, the method comprises scanning the portion of the subject to be restrained to produce a 3D image data set, generating a three dimensional replica of the portion of the subject from the 3D image data set and preparing a clinical restraint using the three dimensional replica. A scanning system for generating the 3D image data set comprising one or more projectors (6) and one or more cameras (8) in combination with an image processing device is also disclosed. The imaging aspects are also applied in the monitoring of the treatment of a patient, the manufacture and fitting of medical items, such as compression hosiery and the like, as well as in the fitting of garments and items of clothing.
Abstract:
Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.

Abstract:
A workflow manager which executes software having one or more channels configured to communicate events-based messages between processes. Events are associated with transitions between states, which mark the progress of an order. An event remains in an associated channel for a period until is retrieved by a peripheral system or expired. When retrieved by a system, the event may trigger a task or process. The workflow manager further includes an event editor, coupled to the workflow manager and configured to retrieve a selected event for editing by a user. The event editor includes a graphical user interface allowing a user to define, monitor, or modify a workflow.
Abstract:
The invention provides a septal occluder for closing a patent foramen ovale (PFO). The septal occluder includes a flexible central portion connecting two occlusion shells for the percutaneous transluminal treatment of an intracardiac defect. The septal occluder includes two occlusion shells connected by an elongate member capable of pivoting or articulating. The elongate member pivots or articulates at the juncture of the occlusion shell and the elongate member, according to one embodiment, or in the center of the elongate member, according to another embodiment. The elongate member can have one or more pivot points.
Abstract:
A method for operating more than one thermal printer adapted to print images by transferring donor material from patches of donor material from a donor ribbon onto a receiver medium, each printer being operable to print images in a manner that exhausts a full donor patch or a fractional donor patch during printing. In accordance with the method, a print order is received and it is determined whether a fractional donor patch set is available for printing at each printer. Portions of the print order are directed to the printers in a pattern that minimizes the number of printers having donor ribbon with a fractional donor patch set available after the printing order has been executed.
