Title: Fractionally spaced maximum likelihood sequence estimation receiver
Inventor: WAN YONGBING
IPC: H04L25/03
Filed: 1993-03-23
Granted: 2002-03-19
Abstract: The channel-impulse-response estimator (44') in a maximum-likelihood-sequence-estimation receiver produces channel-model parameters for a model that produces outputs not only for symbol times but also for intermediate times between the symbol times. A symbol-sequence-derivation circuit (42') determines the most-likely sequence on the basis of metrics computed from the differences between the received signal and the responses of the model to candidate sequences not only at the symbol times but also at the intermediate times. An interpolator (100) receives the symbol decisions from the symbol-sequence-derivation circuit (42') and generates intermediate values from them by simulating the Nyquist filter formed by the concatenation of pulse-shaping filters (22 and 24) in the transmitter and matched filters (36 and 37) in the receiver.      The channel-impulse-response estimator (44') uses these values together with the derived-symbol values as inputs to its updating process to maintain the model.

Patent CA-2114219-C (CA)

IPC: H02K3/12
Filed: 1992-07-29
Granted: 2002-04-30
Abstract: Known flat winding layers that can be prefabricated and inserted into soft magnetic bodies insufficiently utilize the available space in the grooves and winding overhang of polyphase machines and thus increase the volume and weight of the machine. A new winding design allows high power and force densities to be obtained, thanks to the utilization of the whole available space, and are economic to produce. For that purpose each winding layer (4d) is composed of several conductor lanes (22-24) whose number corresponds to the number of phases. The height of the conductor lanes is reduced at the points (25-33) where they intersect,due to the fact that the conductors are mutually offset, and thus pass over each other inside the layer. By variably adapting the width of the conductor the space in the winding overhang through which the magnetic flow is directed in the soft magnetic body is utilized. The space available in the winding overhangs is completely utilized thanks to double winding layers of which each second layer mirrors the first and is offset by a pole pitch with respect to the first. The winding is suitable fox motors and generators whose volume and weight can be advantageously reduced.

Another automatic sorting apparatus comprises two or more endless conveyors having different excursion diameters and disposed one inside another at an interval. The sorting holes of each endless conveyer are smaller than those of the next outer endless conveyor. An inner receiver is disposed inside the innermost endless conveyor for receiving pieces under process falling through the sorting holes of that endless conveyor. An outer conveyor is disposed outside and below a U-turn portion of each endless conveyor for receiving pieces under process falling through the sorting holes of that endless conveyor.

Title: Joint prosthesis augmentation system
Inventor: BROWN ROBERT S
IPC: A61B17/58
Filed: 1996-11-26
Granted: 2005-10-18
Abstract: An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block having an aperture disposed therein. A collet having an expandable distal end, extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a cavity that receives an expansion pin that is adapted to communicate with the collet to expand the collet. The distal end of the collet is adapted to fit within a mounting cavity of a joint prosthesis. With the augmenting block placed on the appropriate surface of the joint prosthesis, the distal end of the collet is positioned within the mounting cavity. Advancement of the expansion pin causes the distal end of the collet to expand, thus frictionally and/or mechanically engaging the interior walls of the mounting cavity to firmly secure the augmenting system to the prosthesis. The expansion pin can include threads which mate with corresponding threads within the cavity of the collet.  Alternatively, the pin and collet cavity can include ratchet and pawl-like surface features.
