Title: Hydraulic fork positioner
Inventor: LUU CHARLIE
IPC: B66F9/12
Filed: 2000-02-01
Abstract: The principle of the invention is to improve:      A) the strength of the frame structure;      B) the smooth positioning operation of the forks; and C) the handling ability of the fork positioner. The fork positioner is attached to the lift truck by a set of hooks bolted onto the back of two mounting plates. The frame of the fork positioner is made by combining two I  beams identical in cross section bolted to the front of the mounting plates. A center key bolt at the back of the top I beam is used to position the fork positioner to the center of the lift truck carriage. A spacer is bolted onto the back of the lower I beam is used to ensure that the lower I  beam is fully supported by the lower carriage bar of the lift truck. Both left-hand and right-hand forks are formed by welding two sets of hooks and a lug to the back of the shank of each fork. Each hook on the fork is installed with a bronze bearing. The bearings fit the profile of these I beams and provide smooth travel of the forks along the I-beams. The operations of these forks are controlled by two hydraulic cylinders. The base of the cylinders are anchored to the frame and the rods are anchored to the lug of the forks. The hydraulic pressurized fluid is supplied equally to the cylinders from the lift truck through the flow divider valve of the fork positioner. When the pressurized fluid is supplied at the base of the cylinders, the cylinder rod extends and the forks open. When the pressurized fluid is supplied at the retainer side of the cylinders the cylinder rods retract and the forks close.

Abstract: This detection device has an armrest that reduces arm strain upon the user.  The armrest is ergonomically designed to fit the user's forearm. The user does not have to shift their concentration from searching due to body fatigue. The principal concern of the invention is to provide an improved lighted inspection mirror that has a unique, versatile, and non restraining armrest for use by law enforcement personnel, military, bomb technicians, corrections personnel, private and governmental security agencies which telescopes and provides a non glare illumination of items. The mirror is detachable and this allows the user to just pop out the mirror if it is broken, rather than replace the whole frame, as it usually required in other surveillance detectors. The mirror has the ability to pop out of its bearing with minimal resistance. The mirror is pivotal and this allows the user to move the mirror as is needed for their investigation. The mirror can pivot and the angle range is from 65 degrees to 200 degrees. The holder that contains the flashlight is also pivotal. The user can determine where to tilt and align the light as required. The light can be angled to where it can give the user greatest illuminousity. The flashlight is designed to not shine directly onto the mirror. Therefore, reducing the glare from the mirror, which competes with the sight that the user is investigating.

Title: Methods and oligonucleotides for detecting nucleic acid sequence variations
Inventor: NADEAU JAMES G
IPC: C12Q1/68
Filed: 2000-04-19
Abstract: The present invention provides methods for detecting and identifying sequence variations in a nucleic acid sequence of interest using a detector primer. It has been found that the reduced efficiency of primer extension by DNA polymerases when the 3' end of a primer does not hybridize perfectly with the target can be adapted for use as a means for distinguishing or identifying the nucleotide in the target which is at the site where the diagnostic mismatch between the detector primer and the target occurs. The detector primer hybridizes to the sequence of interest and is extended with polymerase. The efficiency of detector primer extension is detected as an indication of the presence and/or identity of the sequence variation in the target. The inventive methods make use of nucleotide mismatches at or near the 3' end of the detector primer to discriminate between the nucleotide sequence of interest and a second nucleotide sequence which may occur at that same site in the target. The methods are particularly well suited for detecting and identifying single nucleotide differences between a target sequence of interest (e.g., a mutant allele of a gene) and a second nucleic acid sequence (e.g., a wild type allele for the same gene).

Title: System and method for displaying a three-dimensional object using motion vectors to generate object blur
Inventor: WHITE GEORGE L JR
IPC: G06T13/20
Filed: 2000-05-01
Abstract: A system, method, and computer-usable medium for simulating object blur uses motion vectors. A motion vector, or array of motion vectors, may be specified on either a per-vertex or per-primitive (i.e. per-object) basis. A motion vector is opposite to the direction of the motion, and thus points in the direction of the blur. The magnitude of the motion vector represents the distance the vertex or the primitive (i.e. each vertex in the primitive) travels in one unit of time. When a scene is rendered, only those objects which are in motion, or which are subject to depth of field blurring, are rendered over a series of time slices.      All objects which are static (i.e. nonmoving) are rendered directly into a color buffer, rather than being repeatedly rendered over a series of time slices. Thus, static (i.e. non-blurred) objects are rendered only once, while objects which are to be blurred are rendered over a series of time slices.

Title: Enhanced dual counter rotating ring network control system
Inventor: HURREN ALAN
IPC: H04L69/40
Filed: 2000-06-12
Abstract: A control system enables transport of payload data across a dual counter rotating ring (DCRR) network having two or more nodes, each node providing access to the DCRR network by a respective local area network (LAN) subtending the node. The control system comprises a topology learning entity operative within each node for monitoring individual links of the DCRR, discovering the active topology of the DCRR, communicating topology changes to other nodes in the DCRR, and informing frame forwarding and learning processes of the topology to enable failover to redundant resource upon detection of a network component failure. A frame forwarding process selects a shortest path route between a source and a destination node in the DCRR, and forwards frames to the destination node via the selected shortest path route. An address learning process inspects a source medium access control (MAC) address in each received frame to learn a shortest path route for each MAC address.

Abstract: A method of playing a blackjack-type wagering game where the playing cards have ranks and suits. Initially, the dealer deals a hand to each player making an ante bet and the banker. This dealing step includes the step of hitting each player and the banker as desired thereby. Next, it is determined whether each player has a winning hand, a losing hand or a push hand. For each push hand, it is then determined whether a poker value of that push hand is greater than or less that of the banker's.  Finally, the ante bet of each respective player is paid to (a) each respective player if each respective player has a total hand value considered a winner over a total hand value of the banker or for a push hand if the poker value is greater than the banker's, or (b) the banker if each respective player has a total hand value considered a loser over a total hand value of the banker or for a push hand if the banker's poker value is greater than the player's. In a preferred embodiment, the dealing step includes allowing splits and hitting the hand of the banker until the total hand value is greater than 16.  In addition, the valuing of a poker value is first by rank from higher to lower of ace to 2, and then by suit in the order of higher to lower of spades, hearts clubs, and diamonds.
