Abstract: A method and apparatus for repairing isolated chondral defects using allograft implants. Lesions in articular tissue are corrected by forming a recipient socket in the tissue. A donor graft of a size corresponding to the recipient socket is harvested from a partial tissue specimen obtained from allograft material. The donor graft is implanted into the recipient socket.

Abstract: A method of processing data received at a local system in response to polling a remote device, wherein the local system includes a local clock, the method involving: sending a first poll to the remote device; receiving a response from the remote device to the first poll, the response to the first poll containing data and a time stamp indicating when the remote device responded to the first poll; for the data received in response to the first poll, computing a first time by using both a time that was derived from the local clock for a previous poll of the remote device and also the time stamp contained in the response to the first poll; comparing the computed first time to information that the local system stored in connection with the first poll, wherein the information that the local system stored in connection with the first poll was derived from the local clock; and determining how to process the data received in response to the first poll based on comparing the computed first time to the information that

Abstract: A method of merging a list of newly found network elements and a list of previously known network elements includes arranging the newly found network elements in a hierarchical structure, and determining one or more device matches between each network device in the list of newly found network elements and one or more network devices in the list of previously known network elements. The method further includes, for each of the one or more device matches, determining one or more network element matches between the newly found network element and the corresponding previously stored network device. The method also includes updating the previously found network device corresponding to each of the one or more device matches with the corresponding newly found network device.

Abstract: One or more tethered platforms, each comprising three or more, mill rotors, are operated at altitudes in relatively high winds to generate electricity. These windmill kites use one or more electromechanical tethers on each platform. Their position, attitude and orientation are monitored by one or more GPS receivers and/or gyros and controlled through differential thrusts and torque-reactions produced by the mill rotors. The kites can be electrically powered from a ground supply during relatively calm periods, or landed if desired. During windy periods the kites may be used to generate electricity by tilting the rotors at an angle, or incidence to the on-coming wind. In this generate mode the mill rotors simultaneously develop thrust while generating electricity.

Abstract: A collection and separation device for use in combination with a fluid collection container operatively coupled to a suction source to withdraw body fluids and collect tissue specimens from a patient comprising a tissue collection container operatively coupled between the patient and the fluid collection container having at least one tissue collection basket removably disposed therein to receive body fluids and tissue specimens from the patient including a separator to separate the body fluids and tissue specimens and a fluid collection chamber or zone disposed adjacent the separator such that body fluids and tissue specimens from the patient are received in the tissue collection basket where the body fluids and tissue specimens are separated whereby the tissue specimen is retained in the tissue collection basket for subsequent removal from the tissue collection container and the body fluids are collected in the fluid collection chamber or zone for collection and removal to the fluid collection container.

Abstract: A layer of open cell polyurethane foam adhered to a layer of a non-woven fibrous material of fine porosity relative to the foam results in an efficient fluid (e.g., air) filtering medium having a high capacity for retaining particulate contaminants. The combined layers are useful as an air filter element.
