  • Patent number: 11983994
    Abstract: 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.

  • Publication number: 20240105015
    Abstract: An electronic gaming device includes a display device and a game controller in communication with the display device. The game controller includes a processor and a memory storing instructions, which when executed by the processor, cause the game controller to: cause display of a base game including a plurality of reels; control the plurality of reels to display a combination of symbols corresponding to a primary game outcome; determine that the primary game outcome satisfies a bonus game condition and an enhancement condition to trigger a bonus game having at least one enhanced characteristic; identify outcomes for one or more free spins of the bonus game having the at least one enhanced characteristic; randomly select an outcome for each free spin from the identified outcomes; and initiate the bonus reel game that includes display of the randomly selected outcome for each of the one or more free spins.

  • Patent number: 10144477
    Abstract: 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.

  • Patent number: 8626550
    Abstract: 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.

  • Patent number: 8578346
    Abstract: 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.

  • Patent number: 7231250
    Abstract: A method of setting or adjusting a cardiac pacemaker in a patient diagnosed with cardiac asynchrony, which method comprises the steps of: i) implanting cardiac pacing wires into at least the right ventricle and the left ventricle of the heart of the patient, ii) continuously monitoring and recording the cardiac output, nominal stroke volume and/or arterial pressure of the patient on a beat-by-beat basis, iii) continuously monitoring and recording the respiratory cycle of the patient, and iv) adjusting the conduction delay between the electronic impulses to the cardiac pacing wires until a synchronization of respiratory changes with changes in the cardiac output, stroke volume or arterial pressure of the patient is obtained.

  • Patent number: 6348038
    Abstract: 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. The nominal stroke volume is then determined from the first harmonic and data relating to the arterial blood pressure and heart rate. The nominal cardiac output is then obtained from the nominal stroke volume.

  • Patent number: 6216094
    Abstract: A method of analyzing a signal representing a physical parameter to obtain information from said signal and to extrapolate information contained in said signal and/or to ignore an interfering component in part of said signal, said signal representing either only a first portion of a skew distribution, or a first portion of a skew distribution and a second portion containing an interfering component, in which the area of a skew distribution, preferably a lognormal distribution is measured. The method is particularly applicable to the measurement of cardiac output. Apparatus for carrying out the method is also disclosed.

  • Patent number: 6071244
    Abstract: 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 autocorrelation, whereby the pulsatility and heart rate of the patient are obtained. The nominal stroke volume is then calculated from the pulsatility and the nominal caridac output obtained by multiplying the stroke volume by the heart rate.
