Title: Integral video game and cardio-waveform display
Inventor: CLAYMAN HENRY M
IPC: A61B5/0402
Filed: 1997-06-26
Abstract: A video game which incorporates a video game player's cardio-waveform into the video display and integrates the wave-form with the activities of the video game being played. A cardio-waveform sensor is attached to a video game player. The sensor produces a signal which is transmitted to an input interface of a micro-processor.      A joystick or other control system which enables a player to control the play of the video game is also attached to the input interface of the micro-processor. The micro-processor produces a display signal dependant on the signal's generated from the joystick and cardio-waveform sensor. The player's cardio-waveform is also displayed on the video display and is incorporated into the activities of the game being played. In one embodiment the cardio-waveform represents a boundary which confines the activities of a roaming icon.

Abstract: A RAKE receiver which is employed in a direct sequence spread spectrum communication system, and which can effectively receive multipath signals.  A path searcher measures the amplitude of each path, selects N paths with larger amplitudes in descending order of magnitude, where N is the number of despreaders, and assigns the despreaders to the selected paths to despread the signals of the paths.  This assignment of the despreaders to the paths is carried out such that a path with a large amplitude and a path with a small amplitude are assigned to adjacent despreaders and are input to the same pre-detection combiner.  The outputs of the despreaders are combined by the pre-detection combiners, and detected by detectors whose outputs are RAKE combined by a post-detection combiner.

Abstract: A machine (90) for forming a metal roof panel (50) of indeterminate length from a uniform width supply strip (96) of sheet metal having a pair of parallel straight longitudinal edges (98, 100). The machine (90) has a series of spaced forming stations (102) each having upper and lower shaping rollers between which the sheet metal strip (96) is passed so as to impart a desired shape to the sheet metal strip (96) which is uniform along the length of sheet metal strip (96) after it exits the apparatus.

Title: A process to improve mineral flotation separation by deoxygenating slurries and mineral surfaces
Inventor: NEWELL ANDREW JAMES
IPC: B03D1/02
Filed: 1998-03-13
Abstract: A process for the separation of minerals of different mineralogical character.  The process involves conditioning a milled slurry or flotation concentrate of a mixture of valuable sulphidic minerals and non-sulphidic gangue material with an inert/non-oxidising gas and/or a reducing/deoxifying agent. The conditioning is conducted to achieve a controlled dissolved oxygen content or electrochemical reduction potential conducive to the separation of the valuable sulphidic mineral, non-sulphidic gangue material. The inert/non-oxidising gas and/or reducing/deoxifying agent may be added to the milled slurry or flotation concentrate in a quantity sufficient to increase rejection of the non-sulphidic gangue minerals or to improve the selectivity between the valuable sulphidic minerals and non-sulphidic gangue minerals.

Abstract: Both an apparatus and a method for detecting slag (19) in a flow of molten metal (1) conducted through a ladle shroud (11) are provided. In the apparatus, first (31) and second (33) conductive pins are mounted beside one another in a wall (22) of the laddle shroud (11), the first (31) being in contact with the flow of molten metal (1), but electrically insulated from both the wall (22) and from the second conductive pin (33), the second (33) being in electrical contact both with the wall and with the flow of molten metal (1). A voltmeter (34) is connnected between the two conductive pins (31, 33) for detecting differences in the electrical potential between them as molten metal (1) flows through the shroud (11). Abrupt changes in potential caused by the passage of a metal (1) slag (19) interface through the shroud (11) indicate the presence of slag (19) in the molten metal (1).

Inventor: D AMICO ANTHONY
IPC: A61F5/045
Filed: 1998-08-05
Abstract: A cervical traction device which can be used on a support surface such as a bed which applies a tractive force to the back of the patient's skull approximate to the occipital bone through the use of contoured blocks which can preferably be positioned behind the patient's head and mounted on a head rest assembly.  The tractive force can be administered in a continuous cyclical or intermittent manner controlled by the patient during a cervical traction session.  The device has an integrated damping system which permits return of tractive force to the patient during each cycle in a gradual fashion.  This gradual return enables this unit to closely simulate cyclic, and cyclic intermittent traction performed in the more expensive in-office equipment used by physical therapists.  The head rest assembly slides on the bed or similar surface and can be vertically and laterally adjusted to vary the flexion-extension angle.  The cervical traction device can be operated by the patient with or without the help of a second party.  The mechanism is configured with gas springs to control the rate of descent of the weight and apply a constant tractive force to the patient in a manner which maximizes safety.

Title: Detection of nucleic acids by fluorescence quenching
Inventor: LINN C PRESTON
IPC: C12Q1/68
Filed: 1998-09-22
Abstract: Detector nucleic acids are employed for detection of nucleic acid target sequences by fluorescence quenching mechanisms. The detector nucleic acid comprises at least two oligonucleotides and is partially single-stranded and partially double-stranded. One of the two dyes of a donor/acceptor dye pair is linked to the first oligonucleotide and the other is linked to a second oligonucleotide such that they are in close spatial proximity when the first and second oligonucleotides are base-paired and donor fluorescence is quenched. A single second oligonucleotide may be hybridized to the first oligonucleotide or multiple second oligonucleotides may be hybridized to the first oligonucleotide and to each other, forming a junction structure comprising multiple donor/acceptor dye pairs. The detector oligonucleotide retains its partially single-stranded and partially double-stranded conformation in the absence of target. In the presence of target, however, the second oligonucleotide(s) of the detector nucleic acid is/are completely or partially displaced from the first, increasing the distance between the donor and acceptor dyes and causing a change in fluorescence which may be detected as an indication of the presence of the target sequence.

Abstract: A bottle for perfume and the like has two separate compartments. Each of the two interior spaces (S1, S2) has its own closure/dispenser (e.g. spray fitting or pump) (D1, D2), one at each end, so that two different liquids can be contained and dispensed separately in different ways. An outer container space (S1) is defined between an outer wall (W1) and an inner wall (W2); the inner containing space (S2) is inside the inner wall (W2). The inner (W2) and outer (W1) walls are joined where the neck of the inner-wall container meets the bottom of the outer-wall container. The bottle may include end caps (C1, C2) which cover the two closures/dispensers (D1, D2) at either end, for a symmetrical, elongated shape somewhat like a cigar. The end caps (C1, C2) may also double as closures.
