Patent number: 11983994Abstract: An electronic gaming device includes a display device and a processor configured to execute instructions stored in a memory device. When executed, the instructions cause the processor to at least initiate a primary bonus game in response to a free play trigger condition being satisfied during a base game and determine a number of free spins of a plurality of reels for use during the primary bonus game. The instructions further cause the processor to control the display device to simulate spinning and stopping the plurality of reels in conjunction with sequentially counting up from an initial numerical indicium to a final numerical indicium in association with spinning the plurality of reels according to the determined number of free spins and initiate a secondary bonus game that includes a free spin count-down from the final numerical indicium to the initial numerical indicium.Type: GrantFiled: March 31, 2022Date of Patent: May 14, 2024Assignee: Aristocrat Technologies, Inc.Inventors: David Marsh, Daniel Marston

Patent number: 10144477Abstract: A gear drive balancing scooter is provided that has a left side, a right side, and a center section located between the left and right side. The center section is coupled to the right and left sides through a gear. As the left side moves with respect to the center section, the right side moves in an opposite direction with respect to the center section. Both sides have a respective wheel motor assembly that is used to balance the scooter. To steer the scooter, the user angles one side differently than the other side. The angle of each side determines the rate and direction that each wheel motor assembly rotates. An optional staff extends upwardly from the center section to provide stability.Type: GrantFiled: November 9, 2016Date of Patent: December 4, 2018Inventors: Garrick Theodore Lankford, Michael David Marston, Weiwei Wang, Yong Wang

Patent number: 8626550Abstract: A method, system and apparatus for scheduling subsidiary meeting locations can include sending an invitation to a selection of invitees to a meeting in a collaborative environment for at least one primary location. The method further can include processing both complete acceptances and declinations to the meeting from individual ones of the invitees for the primary location, and also partial acceptances to the meeting from a set of the invitees in the selection. In respect to the partial acceptances, an alternative location to the primary location can be determined which has not already been designated as an acceptable subsidiary location to the meeting. In response, when a number of invitees in the set of invitees exceed a threshold value, the alternative location can be designated as an acceptable subsidiary location to the meeting. Consequently, acceptances can be processed for the set of invitees.Type: GrantFiled: March 31, 2005Date of Patent: January 7, 2014Assignee: International Business Machines CorporationInventor: David Marston

Patent number: 8578346Abstract: Disclosed is a system and method for validating and repairing flow diagrams using a process modeling validation method in conjunction with a process modeling repair method. The process modeling validation method points out structural ambiguities in a flow diagram that can make its automatic interpretation difficult. It also proposes fix to resolve such ambiguities. The method discloses a process semantic annotation scheme that can interpret process semantics in a flow graph implicit in a flow diagram. Further, the validation process compares one or more components of one or more drawings to a set of rules determined by a business process modeling standards and provides a set of semantic errors describing faulty parts of the drawing that do not comply with the business process modeling standards. The process modeling repair method corrects the drawing to ease and enable its automatic interpretation of the flow diagram and make the faulty parts of the drawing comply with the business process modeling standards.Type: GrantFiled: September 10, 2010Date of Patent: November 5, 2013Assignee: International Business Machines CorporationInventors: Tian-Jy Chao, Pankaj Dhoolia, David Marston, Debdoot Mukherjee

Patent number: 6348038Abstract: A method for the measurement of cardiac output in a patient in which the arterial blood pressure waveform of a patient from a blood pressure monitoring device over a period of time is subjected to various transformations and corrections, including a Fourier analysis in order to obtain the modulus of the first harmonic.
