Abstract: An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers (140) facilitates the particulate transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself.  The system employs a multiple o-ring canister assembly (110) which can be attached to either the discharging port (120) or charging port (135) of a piece of processing equipment.  The canister has a series of circumferential o-ring grooves (115) which allows the attachment of a series of individual containers. In a charging mode, once the particulate is charged to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section (149) of the first transfer container. The first transfer container is removed through a bag-out sleeve (143) which is an integral part of the second transfer container. The process is repeated in a stepwise fashion by moving to the next groove in the canister until the process equipment is completely charged in a particulate contained manner.

Abstract: A method of assigning downlink time slots to receive units where the units may generate data using different modulation schemes. The method preferably assigns the downlink time slots as a function of the complexity of modulation schemes employed by the units. Further, the method preferably assigns the time slots from the least complex modulation scheme to the most complex scheme. The method may further assign uplink time slots to transmit units where the transmit units may generate data using different modulation schemes. The method preferably assigns the uplink time slots as a function of the complexity of modulation schemes employed by the uplink units. Further, the method preferably assigns the uplink time slots from the least complex modulation scheme to the most complex scheme. In other embodiments, the downlink time slots are assigned as a function of the bit per symbol rate employed by the receive units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate. Further, the uplink time slots are assigned as a function of the bit per symbol rate employed by the transmit units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate. The present invention is also a method of simplifying the encoding of a predetermined number of bits of data into frames. The method adds error coding bits so that a ratio of the frame length times the baud rate of the frame times the bit packing ratio of the data divided the total bits of data is always an integer. The method may also convolutionally encode the bits of data so that the same equation is also always an integer. The present invention is also a method of updating the weights of a FIR filter where the filter processes symbols having variable modulation rates. When the modulation rate of the incoming symbols changes, the weights corresponding to the first symbol having the new modulation rate are changed based as the symbol propagates through the filter.

Abstract: An ink manager running at a computer system receives ink information entered at a pen-based input/display device and accumulates the ink information into ink strokes. The ink manager communicates with a handwriting recognition engine and includes an ink phrase termination engine that is configured to detect the occurence of one or more ink phrase termination events by examining the ink information. Upon the occurrence of an ink phrase termination event, the ink manager notifies the handwriting recognition engine and organizes the preceding ink strokes into an ink phrase data structure. The ink manager may also pass the ink phrase to an application executing on the computer system that is associated with the ink information, and it, in response, may return a reference pointer and a recognition context to the ink manager. The reference pointer and recognition context are then appended to the ink phrase data structure. Utilizing the recognition context identified by the application, the handwriting recognition engine generates one or more hypotheses for the ink phrase, and provides them to the ink manager. The ink manager forwards the hypotheses together with the reference pointer to the application and may also append them to the ink phrase data structure.

Abstract: A constraining sheath for use around an endoprosthesis (e.g., a stent device, with or without a graft covering), which may be a balloon expandable endoprosthesis but more preferably is a self-expanding prosthesis. The endoprosthesis is coaxially enclosed within the constraining sheath, which is an outer, disruptable, preferably implantable tubular sheath, preferably made of ePTFE. The constraining sheath and endoprosthesis are preferably mounted together as an assembly on an angioplasty balloon for delivery. Deployment of the endoprosthesis entails inflating the angioplasty balloon to a pressure sufficient to disrupt or break the constraining sheath in a prescribed fashion, thereby allowing a self-expanding endoprosthesis to spontaneously deploy. The constraining sheath of ePTFE may be attached to the endoprothesis and implanted along with the device, or alternatively attached to the balloon catheter shaft and removed with the balloon catheter. The angioplasty balloon's working length is preferably shorter than the length of the endoprosthesis. A endoprosthesis assembly incorporating a constraining sheath according to one embodiment of the invention is also provided with an additional packaging sheath.
