Title: Bit-splitting for pulse width modulated spatial light modulator
Inventor: DOHERTY DONALD B
IPC: G09G3/34
Filed: 1996-08-26
Abstract: A method of implementing pulse-width modulation in a display system (10, 20) that uses a spatial light modulator (SLM) (15). Each frame of data is divided into bit-planes, each bit-plane having one bit of data for each pixel of the SLM and representing a bit weight of the intensity value to be displayed by the pixels. Each bit-plane has a display time corresponding to a portion of the frame period, with bit-planes of more significant bits having longer portions. Then, the display times for one or more of the more significant bits are segmented so that the data for those bits can be displayed in segments rather than for a continuous time. (FIGURE 3A).  The segments are distributed throughout the frame period to reduce visual artifacts. (FIGURE 3B).

Title: Locking arrangement
Inventor: STEINBRINK WILFRIED
IPC: E05B27/04
Filed: 1996-09-03
Abstract: A locking arrangement has a plurality of cylinder locks having a cylinder core (14) in an outer core (13). The cylinder core (14) can be actuated by rotation by means of a master key or a suitable individual key (16'). The outer core (13) is rotatably supported in a cylinder housing (12). Spring-loaded tumbler pins (21a to 26c) which are divided into different segments (a, b, c) are arranged in the cylinder housing (12), the outer core (13), and cylinder core (14). In order to increase the security of the locking arrangement, the outer core (13) only extends over a partial length (34) and accordingly over only some of the spring-loaded tumbler pins (23a to 26c), while the rest of the spring-loaded tumbler pins (21a to 21c) are covered by an auxiliary outer core (13') which can be rotated together with the cylinder core via an individual key (16'). This individual key (16') has a rib (32') on its back which is shorter than that of the respective master key. The auxiliary outer core (13') has a continuous slot (31') for the engagement of the rib (32') and the rib (32') of the individual key (16') extends at most until the inner end (35) of the auxiliary outer cylinder (34').

Patent CA-2194972-A1 (CA)
Title: Frame synchronization in multicarrier transmission systems
Inventor: ASLANIS JAMES T
IPC: H04L5/06
Filed: 1995-07-11
Abstract: A discrete multitone modulation transmission system is described in which frame synchronization is monitored at the receiver by correlating frequency domain complex amplitudes of a synchronizing frame with a stored synchronizing pattern. If the correlation result falls below a threshold, indicating a loss of frame synchronization, a plurality of correlations are performed, in each case using the stored complex amplitudes of the synchronizing frame multiplied by a respective complex value representing a respective complex derotation corresponding to a respective possible time shift of the synchronizing frame.  The best correlation result, if it exceeds another threshold, indicates a time shift for restoring frame synchronization, this being possible before the next synchronizing frame is received.

IPC: C12Q1/68
Filed: 1997-07-22
Abstract: .alpha.-Boronated deoxynucleoside triphosphates, when incorporated into a double-stranded restriction endonuclease recognition/cleavage site for a restriction endonuclease, induce nicking by the restriction endonuclease .alpha.-Boronated deoxynucleoside triphosphates (dNTP.alpha.

Patent CA-2208000-A1 (CA)
Title: Side-pumped lasers
Inventor: HOBBS JOHN W
IPC: H01S3/094
Filed: 1995-12-18
Abstract: Methods and apparatus for side pumping lasers are disclosed. By pre-collimating radiation emitted by laser diode arrays (62, 66), the present invention provides transverse mode matching to achieve fundamental, or TEM00, mode operation in the corresponding (nominally vertical) axis. Optics associated with the resonant cavity (106, 114, 110, 118) additionally redirect energy longitudinally through the gain media, enhancing fundamental mode operation in the (nominally horizontal) other axis as well. With dual forty-watt linear arrays of laser diodes (62, 66) and four longitudinal passes, TEM00 mode outputs exceeding fifteen watts have been achieved. By de-tuning the pumping radiation from the absorption peak of the lasing material (14) improved matching of pumping energy to the lasing volume is achieved.

Abstract: A method is provided for forming a molten oxide ceramic electrode for a plasma arc ignited between first and second electrodes within a plasma arc chamber, wherein the conductivity the oxide ceramic is a function of temperature alone. Following ignition of the plasma arc, a mixture is formed of a small quantity of molten oxide ceramic and a sufficiently high concentration of a volatile contaminant to render the mixture electrically conductive.

Title: Automatic in-process gauging of ground shafts
Inventor: SOMMERS ALLEN
IPC: B24B49/00
Filed: 1997-11-12
Abstract: The gauging system for measurement of ground shafts during grinding has a gauge unit mounted on a slide and cylinder assembly for forward/reverse travel between a home position and an operating position. The gauge unit has spaced-apart finger probes extending therefrom with opposing distal tips biased towards each other, the gauge unit thus providing a signal indicating a distance between the distal tips. In the home position the tips are positioned on a gauge master, and in the operating position they are positioned on the shaft being ground. The gauge master is used to zero or calibrate the gauge during each machine cycle. The grinding is stopped when the desired shaft diameter is reached, as indicated by a signal from the gauge unit. Roundness and accuracy are then verified at a lower rpm.
