Title: Multimode digital modem
Inventor: WU SONG S
IPC: H04L1/00
Filed: 1997-10-01
Granted: 2005-08-02
Abstract: A modem that operates selectively in the voice-band frequency band and at higher frequency bands is provided. This modem supports multiple line codes, like DMT and CAP.      The modem uses a Digital Signal Processor (DSP), so that different existing ADSL line codes, such as Discrete MultiTone (DMT) and Carrierless AM/PM (CAP), can be implemented on the same hardware platform. The modem negotiates in real-time, for a desired line transmission rate to accommodate line condition and service-cost requirement.      The line code and rate negotiation process may be implemented at the beginning of each communication session through the exchange of tones between the modems. A four-step MDSL modem initialization process is provided for line code and rate compatibility.      A new synchronization startup procedure for CAP based MDSL modems is provided. The handshake protocol and receiver algorithm allow reliable modem synchronization over severely amplitude distorted channels such as standard telephone twisted-pair wire. The algorithm makes use of a short length sequence to train a synchronizing equalizer at the receiver. After training to this sequence, a matched filter or correlator is used to detect the inverted sync sequence. The detection of the inverted sequence signals the start of the normal reference training of the CAP demodulation equalizers.      The MDSL line connection management process provides a simple, efficient, and flexible interface to manage the line connection between MDSL-C (MDSL in Central Office site) and MDSL-R (MDSL in resident site) in the telecommunication Wide Area Networking environment. An internal state machine in an MDSL modem records and monitors the line status and notifies the state change to the other MDSL and also the host processor. The protocol used for exchanging line connection management messages is a simplified Link Control Protocol (LCP) for MDSL.

Abstract: A middle expanded, removable disk im-plant (22) with substantially rectangular cross--sectional shape with a minimal height (H) and a width (W) greater than the height which is de-tachably mounted to an applicator (52) for in-sertion into the anatomical region between two adjacent vertebrae (16, 18) from which a por-tion of the intervertebral disk has been removed. The implant is positioned by anterior-posterior movement in the disk space to the position in which both the expanded middle portion and the smaller diameter end (25, 36) portions of the im-plant engage the bodies (12, 14) of the adjacent vertebrae and then rotated to bring the sides (34) of the implant defining the height of the implant into engagement with the bodies of the adjacent vertebrae. A lock (24) is then secured to the im-plant to prevent further rotation thereof. In the event the adjacent vertebrae need to be aligned before fusion, an elongate implant (112) is pro-vided which is split longitudinally into side-by-side members (113, 114) movable relative to each other and which is inserted into the disk space between two misaligned vertebrae (133, 137). The members are provided with teeth (138) for engaging the adjacent vertebrae and the implant formed by the two side-by-side members is rectangularly-shapedin cross section, the height (H6) of the rectangularly-shaped cross section being less than the width (W6) so that the implant can be inserted between the adjacent vertebrae with the lesser, height dimension oriented in the same direction as the axis of the spinal column and the larg er width dimension at approximately a right angle to that axis. One member is then moved relative to the other from the first side-by-side position along the longitudinal axis of the implant to a second position in which the members are aligned with the respective, adjacent, misaligned vertebrae and the implant is rotated 90.degree. to engage the teeth to the bodies of the adjacent vertebrae. The two members are then brought back into the first side-by-side position to draw the vertebrae into alignment and the implant is rotated approximately 90.degree. to disengage the teeth from the vertebrae for removal from the disk space.

Abstract: A pump which has a piston (30) which is reciprocatingly moved inside a tubul ar housing (32) to extract fluid from the bottom of a well (29). The piston (30 ) is driven by motor (12) and has a horizontally extending base plate (50) wit h opening (52) provided with a plug/check valve (64). As the fluid is pumped, the plug (64) is raised and the fluid flows into a high pressure reservoir (35). When the pressure inside reservoir (35) exceeds a specified level, the  base plate (50) is moved downward against an upward biasing force. This open s an annular port (51) exposing bleed ducts (56) and allows some fluid in reservoir (35) to flow back into low pressure chamber (37). Grooves (43) are  also provided on the peripheral surface of base plate (50) for allowing smal l amounts of fluid to continuously escape from the reservoir (35) as long as pressure in the reservoir (35) is higher than in low pressure chamber (37). This allows the pump to idle at start-up and starts the pump smoothly, as we ll as preventing overpressure conditions.

Abstract: A method of microdissection which involves: forming an image field of cells of the tissue sample utilizing a microscope, identifying at least one zone of cells of interest from the image field of cells which at least one zone of cells of interest includes different types of cells than adjacent zones of cells, and extracting the at least one zone of cells of interest from the tissue sample. The extraction is achieved by contacting the tissue sample with a transfer surface that can be selectively activated so that regions thereof adhere to the zone of cells of interest to be extracted. The transfer surface includes a selectively activatable adhesive layer which provides, for example, chemical or electrostatic adherence to the selected regions of the tissue sample. After the transfer surface is activated the transfer surface and tissue sample are separated. During separation the zone of cells of interest remains adhered to the transfer surface and is thus separated from the tissue sample and may be molecularly analyzed.
