Patent CA-2264954-A1 (CA)
Inventor: ITO JIRO
IPC: H04N9/31
Filed: 1998-10-09
Abstract: In a projection display device, emergent light from an illumination optical system is diffused by microlenses provided in a liquid crystal light valve. Emergent light from the liquid crystal light valve diffused by these microlenses is efficiently drawn into a projection optical system whose f-number is set to be less than the f-number of the illumination optical system. As a result, it is possible to prevent light utilization efficiency from being deteriorated due to light diffusion by the microlenses.      Consequently, it is possible to obtain a bright projection image in a projection display device in which a liquid crystal light valve having microlenses is incorporated.

Title: Combined interference cancellation and maximum likelihood decoding of space-time block codes
Inventor: NAGUIB AYMAN F
IPC: H04B7/06
Filed: 1998-10-06
Abstract: Block-encoded transmissions of a multi-antenna terminal unit are effectively detected in the presence of co-channel interfering transmissions from other multi-antenna terminal units, when the base station has a plurality of antennas, and interference cancellation is combined with maximum likehood decoding. The signals received in one base station antenna are employed in processing the signals received in a second base station antenna so as to cancel the signals of one terminal unit, while decoding the signals transmitted by the other terminal unit. Zero-forcing and MMSE approaches are presented. In another embodiment of the invention, the basic decoding approach is used to obtain an initial estimate for the symbols from each terminal. Assuming that the signals of the first terminal unit has been decoded correctly, the receiver employs this initial decoded signal of the first terminal unit to cancel their contribution to the signals received at the base station antennas while decoding the signals of the second terminal unit. This process is then repeated assuming that the signals of the second terminal unit have been decoded correctly; the receiver employs this initial decoded signal of the second terminal unit to cancel their contribution to the signals received at the base station antennas while decoding the signals of the first terminal unit. The above disclosed techniques are variable for any number K of terminal units concurrently transmitting over a given channel, where each terminal unit is using a space-time block code with N transmit antennas, and a base station has at least K receive antennas.

Title: Proximal actuation handle for a biopsy forceps instrument having irrigation and aspiration capabilities
Inventor: TURTURRO VINCENT
IPC: A61B19/00
Filed: 1998-02-03
Abstract: A biopsy forceps instrument is provided having a proximal actuation handle, a flexible multi-lumen tubular member, at least one control member extending through a lumen, an irrigation means, an aspiration means, and a distal assembly. The proximal actuation handle includes a shaft and a spool slidably mounted on the shaft. The actuation handle is coupled to the proximal ends of both the flexible tubular member and the control member. Lumens of the tubular member form irrigation and aspiration conduits. The distal assembly includes a hollow jaw cup coupled to the aspiration conduit and a hollow movable jaw coupled adjacent the irrigation conduit. The movable jaw is coupled to the control member, such that actuation of the actuation handle moves the movable jaw relative to the jaw cup. Moving the hollow jaws into a closed position provides a substantially fluidtight coupling between the irrigation and aspiration conduits. The actuation handle is also provided with an assembly to control irrigation to and aspiration from the distal assembly. A proximal sample chamber having a removable screen is provided for filtering tissue samples aspirated from the distal assembly. The jaws are activated to cut a tissue sample and the irrigation and aspiration means are activated to move the sample into the sample chamber for retrieving the sample without removing the instrument from a patient.

Abstract: A training projectile (10) that utilizes flutes (120) or flats (220) to augment roll damping characteristics and thereby cause the projectile to crossover into a gyroscopically unstable trajectory pattern at a predetermined time. Prior to the crossover, the training projectile maintains a gyroscopically stable trajectory while enables extrapolation to ascertain the trajectory of a non-training projectile that does not have an augmented roll damping section (100). The unstable trajectory pattern substantially reduces the distance the training projectile (10) can traverse, thereby reducing the amount of area required for a training range.

Abstract: A diagnostic test unit for deterministically measuring one or more parameters, such as dead band, dead time, response time, gain, or overshoot, of a process control device that is connected in a process control loop during operation of a process includes a switch controller, a signal generator, a switch, a response accumulator mechanism, and an analyzer mechanism. The swtich controller monitors a process signal during operation of the process to determine whether the process signal is substantially stable. In the event that the process signal is substantially stable, the switch replaces a control signal with a diagnostic test signal generated by the signal generator. The response accumulator is in communication with the process control loop to obtain an indication of the response of the process control device to the diagnostic test signal. The analyzer unit then determines the device parameter from the test signal and the response indication.
