  • Publication number: 20240131268
    Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

  • Publication number: 20240112540
    Abstract: An electronic gaming device including a display device, a memory device storing instructions, and a processor in communication with the display device and the memory device is described. The instructions, when executed by the processor, cause the processor to cause display of a plurality of symbols, present an output amount, determine that the plurality of symbols includes a plurality of consolidating symbols, cause display of the plurality of consolidating symbols consolidating into a consolidated symbol, fill any vacant symbol positions with new symbols, determine a second output amount, and present the second output amount. The instructions also cause the processor to cause display of a third plurality of symbols, the third plurality of symbols and the consolidated symbol defining a fourth plurality of symbols, determine a third output amount based upon the fourth plurality of symbols, and present the third output amount.

  • Publication number: 20240112529
    Abstract: Disclosed are video slot games, including Class II and III gaming machines and systems, comprising a five reel video (5RV) arrangement that includes metamorphic symbols that incrementally expand, enlarge, balloon, widen, lengthen, or grow, e.g., when the metamorphic symbol lands on a predetermined position, or a winning payline, and that communicate the effect to the player of the incremental growth or increase in size by providing an enhanced user interface with information about the player's progress toward a potential special awards or status. The metamorphic symbols may incrementally expand, enlarge, balloon, widen, lengthen, or grow with each successive winning land, and may, in some examples, ultimately snap, crack, pop, deflate, or explode, while optionally deforming adjacent presentations to provide various award enhancements.

  • Patent number: 11948427
    Abstract: An electronic gaming machine includes a processor configured to control at least one display device to display at least one of a matrix of symbol positions and a plurality of multipliers, and to evaluate a bingo card to determine a bingo game outcome. The processor is also configured to evaluate a bingo card to determine a bingo game outcome, and to determine whether the bingo game outcome is a winning outcome. If the bingo game outcome is a winning outcome, the processor is also configured to determine an award value associated with the winning outcome, and to obtain an award quotient based at least in part on the award value and a value of at least one multiplier of the plurality of multipliers. In addition, the processor is configured to determine a winning reel outcome associated with the award quotient, where the winning reel outcome includes a winning plurality of symbols.

  • Publication number: 20240087415
    Abstract: A slot type game with one or more dynamic paylines and/or dynamic payline modifiers includes a grid or matrix of symbols for which one or more symbol outcomes may be determined and presented. In embodiments with a dynamic payline, the slot type game also includes a payline determination for which a payline outcome may be determined and presented. The payline outcome may correspond to positions of symbols in the grid or matrix and may determine whether or not the corresponding symbols in the grid or matrix are winners. In embodiments with a dynamic payline modifier, the slot type game also includes a payline modifier for which a payline modifier outcome may be determined and presented. The payline modifier outcome may correspond to positions of symbols in one or more paylines and may determine whether or not the one or more paylines and/or symbols are modified.

  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Publication number: 20240009550
    Abstract: Embodiments of the disclosure provide an electronic gaming machine, systems and methods with a wheel feature mode dependent on base game outcomes. Specifically, a gaming machine comprises a user interface, a display device, and a game controller. The wheel feature mode is triggered during a base game based on wheel feature mode trigger conditions. The wheel feature mode animates a graphical user interface to present a spinning feature wheel that provides credit value awards, dependent on base game outcomes (e.g., one or more base game bingo pattern outcomes), through a sequence of player-initiated feature wheel spins. If one or more winning base game outcomes remain in the base game, the wheel feature mode continues with each wheel slice value reset, such that the minimum wheel slice value is equal to or greater than the previous spinning feature wheel credit value award which continues until no winning base game outcomes remain.

  • Publication number: 20230080994
    Abstract: A free spin count-up bonus game and a subsequent banked free spin count-down secondary bonus game are described herein. The free spin count-up game may be triggered during play of a base game. A numerical indicium may be provided. During the free spin count-up bonus game, the indicium may count up from an initial value to a final value. When the indicium reaches a maximum or final value, the value may be regarded as indicating a number of “banked” free spins. The number of banked free spins may be compared to one or more threshold values. If the number of banked dree spins is greater than or equal to one or more threshold values and there is a successful outcome on a random determination, a secondary bonus game may be initiated, during which the indicium is decremented from the final value back down toward the initial value.

  • Publication number: 20230081422
    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.
