Title: Apparatus and method for equalizing a corrupted signal in a receiver
Inventor: LABEDZ GERALD P
IPC: H04L27/38
Filed: 1991-12-17
Abstract: An equalization system for equalizing a corrupted signal is disclosed. The equalization system includes a complex matched filter (400) and a maximum likelihood sequence estimator (MLSE) (405) for removing the effects of phase shift, amplitude variations, intersymbol interference, etc. resulting from multi-pathing and noise contributed by the receiver front end. The system estimates a correlation signal C(t) (505) and synchronizes C(t) (505) to maximize its energy as seen on the taps of the complex matched filter (400). Taps having amplitude coefficients below a predetermined threshold are set to zero to produce a modified CIR estimate. The modified CIR estimate which has had the effects of noise virtually eliminated, is then used to construct the complex matched filter (400) and is also used as input to the MLSE (405) to produce a better equalized data signal.

Title: Sign stand
Inventor: GARDNER DONALD A
IPC: G09F7/20
Filed: 1993-09-15
Abstract: ABSTRACT OF THE DISCLOSURE         A sign stand for mounting a sign in a specific position above a concrete barrier extending alongside a roadway.  An inner portion of a base plate is secured under the barrier and a collar extends upwardly from an outer portion of the base plate.

Title: Video merging employing pattern-key insertion
Inventor: HANNA KEITH J
IPC: H04N5/272
Filed: 1992-09-10
Abstract: Disclosed is a technique for deriving a composite video image by merging foreground and background video image data supplied from a plurality of separate video signal sources employing pattern-key insertion, rather than prior-art color-key insertion, for this purpose.      Pattern-key insertion involves replacing a first pattern (202) in a video scene (204A) with a second pattern (204B). This is accomplished by first detecting the first pattern (202) in the video scene and estimating the pose of this detected first pattern with respect to a reference object in the video scene. The second pattern is then geometrical-ly transformed using the pose estimate of the detected first pattern. Finally, the detected first pattern is replaced with the geometrically-transformed second pattern.

Title: Laser diode distance measurement
Inventor: MEINZER RICHARD A
IPC: G01S17/32
Filed: 1992-11-19
Abstract: A laser diode distance measurement device includes a laser diode (10) which emits light (20) to a lens (22) which provides focussed light (24) incident on a target (26). The light (24) is reflected from the target (26) back to the laser diode (10) which causes the laser diode (10) to emit a light (28) which exhibits intensity pulses (due to coherent interference) related to the distance (L) to the target (26). A photodetector (30) provides a feedback signal indicative of the intensity of the light (28) to a distance measurement circuit (18). The laser diode (10) is driven by an up-ramp signal that reduces electronic processing and at a frequency that reduces speckle noise. The distance measurement circuit (18) blanks out a portion of the feedback signal during discontinuities of the laser diode drive signal to minimize associated noise from distorting the distance measurement.

Patent CA-2132269-A1 (CA)
Inventor: DOERRER RAINER H
IPC: G01N15/14
Filed: 1994-09-16
Abstract: An automated interactive cytology system provides expedited handling of samples, minimizing false negatives, while not substantially increasing the number false positives. A computerized system identifies and displays the cells which are of greatest interest to the cytologist. The system then processes this information on all cells identified to classify the slide as normal, abnormal, or questionable based on a statistical analysis of cells meeting given criteria. Before displaying the results of the statistical analysis, a cytologist reviews the cells which the computer has determined to be most significant. It is only then after the cytologist has determined whether the cells are positive, negative, or questionable, that the determination is inputted into the automated system. The automated system then compares the cytologist's analysis with its own statistical analysis. Based on the two opinions, the cytologist determines how to advise a doctor regarding the sample.
