Abstract: A device and method for selectively engaging or penetrating a layer of a luminal organ wall where the luminal organ wall has a plurality of layers including an outermost layer and an innermost layer adjacent to the lumen of the organ. The device and method select one of the plurality of layers of the organ wall other than the innermost layer and deploy from within the lumen of the organ a tissue device through the innermost layer to a specific depth to engage or penetrate the selected one of the plurality of layers. The device and method may be employed to create luminal pouches or restrictive outlets. In a stomach organ, the device and methods may be employed to treat obesity by forming a gastric pouch with or without a restrictive outlet.

Abstract: An UWB Transceiver for Multi-Band OFDM communication including an antenna switch (342), a receive front end and down-converter (303), an up-converter and power amplifier (305), and a frequency synthesizer (211). The transceiver achieves high dynamic range by employing a synthesizer (211) with very low spurious components and a receive front end with an efficient receive RF filtering embodiment. The synthesizer (211) may rapidly switch frequencies in a manner that minimizes spurious components outside the band group used for communication. The receiver (200) also achieves high selectivity and sensitivity by dividing the receive signal path into even and odd band groups.

Abstract: Enhancing the sound quality of a mechanical acoustic sound generation device that has a plurality of notes that have a perceived low sound quality by digital sampling the corresponding notes of a mechanical acoustic sound generation device and playing them in conjunction with the notes of the device when a note having a lower perceived sound quality is generated by the device.

Abstract: A sorting system and method that sorts records based on multiple fields by converting the fields to a common data type and sorting the common data type fields using a single sorting algorithm whereupon the records can be ordered based on the sorted common data type fields. The single sorting algorithm can quickly, efficiently, and accurately sort the records because the index fields have been converted to appropriate simple values in a common data type.

Abstract: A method and apparatus of detecting a tandem link and performing tandem tunneling when a tandem link is detected. The detection of a tandem link includes generating a HAIL and ACK signal where a voice compression unit on one end of the link receives the signals and generates an ACK signal for a voice compression unit on the other end of the link when the HAIL signal is detected. The tandem tunneling prevents the VCUs that comprise the tandem link from decompressing packets received on a network link, adds HDLC header information to the packet to generate HDLC framed packets on the subscriber side, removes HDLC header information from HDLC framed packets received on the subscriber side, and passes the unframed packets to the network side.

Abstract: A complex frequency shift keyed homodyned diplexed radar system and method that can accurately determine the range of one or more targets where the targets have little or no velocity relative to the radar system. The system and method generates a FSK electromagnetic wave that is reflected off the one or more targets and converted into a delayed or phase shifted baseband signal and undelayed baseband signal where the delayed and an undelayed baseband signal may be analyzed to determine the range of the one or more targets.

Abstract: An apparatus and method for advancing and extracting a component from a tube or channel of a magazine by the employment of a vacuum to a port that engages an open proximal end of the tube or channel of the magazine where the vacuum is sufficient to advance and hold the component as the head is moved away from the proximal end in a direction parallel to the long axis of the tube or channel of the magazine.

Abstract: A method for producing a cephalometric lateral profile usable for growth forecasts and treatment simulations particularly for use by orthodontists and maxillo-facial surgeons in planning treatments for their patients. The method includes obtaining a lateral cephalometric x-ray and image of a subject, e.g. by an x-ray machine and a video camera, creating a polyline outline of the lateral profile of the image, identifying a set of pre-defined points on the outline, and converting the polyline outline to a corresponding series of Bezier curves using the identified points as anchor points. The pre-defined points preferably include a set of points on the polyline outline at which the ratio of the subject's soft tissue to the subject's hard tissue is known, e.g. the glabella, the soft nasion, the tip of the nose, the subnasal, the soft A-point, the upper lip, the upper lip embrasure, the lower lip embrasure, the lower lip, the soft B-point, the chin, and the soft menton.

Abstract: A method and apparatus for flipping or rotating a component 180 degrees. The apparatus includes a rotatable plate having a component opening where the component may pass through and a top and a bottom shutter where when the plate is rotated in a first direction, the top shutter closes and the bottom shutter opens and when the plate is rotated in a second, opposite direction, the bottom shutter closes and the top shutter opens. The top shutter and the bottom shutter may be coupled to a proximal and distal cam following bearing where the proximal and distal cam following bearings are located within a proximal and distal cam slot of a cam barrel.

Abstract: A synchronized frequency hopping method and apparatus for use in a cellular communication system where the cellular communication systems has a plurality of cells and a plurality of frequencies available to be assigned to the cells. At predetermined times, cells in the system synchronously change or hop to a new frequency. The new frequency to which a cell hops to may be a function of the present frequency the cell is assigned. In addition, synchronized frequency hopping may occur at predetermined intervals and the pattern of hopping may periodically repeat. This technique limits the period of time a non-system source of interference may impair communications in any cell since the cell hops to different frequencies periodically.

Abstract: A flexible forceps device comprises a distal end to be inserted into a patient, a proximal end to remain outside the patient and a flexible, elongated body extending between the ends. The flexible body has at least one lumen and may have a smooth, sealed external surface. An effector assembly is attached to the distal end and includes a support piece and at least one movable element. A control assembly is attached to the proximal end and includes a push-pull mechanism. A coaxial actuating assembly extending through the lumen of the flexible body consists of a flexible tube having a lumen, with a control wire slidably disposed within the lumen of the tube. The tube provides a flexible, yet relatively incompressible column support between the effector assembly and control assembly. The proximal end of the control wire is attached to the push-pull mechanism and the distal end is linked to the movable elements, whereby operation of the control assembly moves the movable elements relative to the support piece.

Abstract: A flexible biopsy forceps device for acquiring more than one tissue sample comprises an elongated, flexible body having a central lumen and having a proximal end and a distal end. A control assembly is adjacent to the proximal end of the flexible body and a jaw assembly is coupled to the distal end. A jaw actuating means extends from the control assembly to the jaw assembly. The jaw assembly includes a pair of jaws that pivot from an open position to a closed position in response to movement of the jaw actuating means to surround and excise tissue samples. In their closed position, the jaw pair has a proximal opening aligned with the central lumen of the flexible body sized to allow passage of tissue samples. An intake means is disposed within the distal portion of the central lumen and may extend into the proximal opening of the jaw pair.

Abstract: Disclosed herein are methods and apparatus for detecting the presence of a CDPD carrier in a channel of a cellular system (although the invention is broadly applicable to detecting a specific kind of carrier associated with an "overlay" system, wherein an "overlay" system is one that shares the frequency allocation of another system on a non-cooperating basis). This specification describes a spectral estimation technique for detection of a CDPD carrier. In addition, this specification describes an MMSE (minimum mean-squared error) method that improves on the spectral estimation method.
