Abstract: A differential space-time block coder produces successive space-time blocks of symbols from M-PSK symbols to be encoded, in accordance with an orthogonal matrix and a normalization factor. Differentially encoded space-time output blocks, for transmission via a plurality of transmit antennas (16, 18) of a wireless communications system, are produced by multiplying (42) each space-time block from the space-time block coder (40) by the respective previous (44) differentially encoded space-time output block. Decoding is independent of channel estimation, and the arrangement is simple, avoids error propagation, and is applicable to different numbers of transmit antennas.

Abstract: Disclosed is method for measuring a change in a cellular morphological parameter, for example, the position and/or the shape of a cell. The method comprises labelling a population of cells with a marker substance which is in a non-detectable state, but which may be caused to become detectable by exposure to light of a suitable first wavelength. By exposing a sub-population of labelled cells to light of an appropriate first wavelength in a predetermined pattern, the sub-population of cells may be defined in which the area covered by the sub-population conforms to the pattern of illumination used. Subsequent examination of at least a portion of the population of cells using illuminating light of a second wavelength selected to be suitable for detection of the marker, will reveal patterns of distribution of the marker substance indicative of a change in said cellular morphological parameter.  Also described and claimed is a method for screening for a test agent whose effect on the cellular morphological parameter is to be determined.

Abstract: Changeover clutch discs for a direct coupling clutch and a change-speed clutch, respectively, are disposed in two stages in a radial direction across a movable element which can move in axial directions of an input shaft.   A carrier and the movable element are brought into meshing engagement with each other such that the movable element does not rotate relative to the carrier. The changeover clutch discs mesh with clutch discs which are disposed on the input shaft and a casing, respectively. A coned disc spring and an electromagnetic actuator are disposed such that operating directions of the spring and the actuator are opposed to each other. The coned disc spring keeps the direct coupling clutch in a normally engaged condition with its biasing force, and the electromagnetic actuator brings a change-speed clutch into engagement after it has released the engagement of the direct coupling clutch by virtue of its thrust.

Abstract: A rotary pulser for transmitting information to the surface from down hole in a well by generating pressure pulses encoded to contain information. The pressure pulses travel to the surface where they are decoded so as to decipher the information. The pulser includes housing containing a stator forming passages through which drilling fluid flows on its way to the drill bit, a rotor, and a replaceable wear sleeve enclosing the rotor. The rotor has blades that are capable of imparting a varying obstruction to the flow of drilling fluid through the stator passages depending on the circumferential orientation of the rotor, so that rotation of the rotor by a motor generates the encoded pressure pulses. The rotor is located downstream of the stator and the rotor blades are shaped so that when the motor is not in operation, a hydrodynamic opening torque is imparted to the rotor that tends to rotate the rotor blades away from the circumferential orientation that results in the maximum obstruction and toward the circumferential orientation that results in the minimum obstruction. A torsion spring provides a mechanical force that also tends to rotate the rotor into the orientation that provides the minimum flow obstruction.
