Abstract: Disclosed are methods, systems and non-transitory computer readable memory for gesture control. For instance, a system may include a wearable device configured to be worn on a portion of an arm of a user. The wearable device may include a plurality of electrodes disposed on an interior of the wearable device and configured to obtain biopotential signals from the user's arm; and a biopotential chip. The biopotential microchip may be configured to output, directly or indirectly, biopotential data, acceleration data, and/or angular rate data, or derivatives thereof (“gesture data”), to a machine learning classifier. The machine learning classifier may be configured to generate, based on the gesture data, a gesture output indicating a gesture performed by the user. In some cases, the plurality of electrodes may include one or more wristband electrodes and/or a plurality of hub electrodes in a hub. In some cases, the hub may be curved.

Abstract: New apparatuses and methods for introducing varying levels of skill into wagering games that have historically been games of luck or strategy are provided. A card value and suit is invisible or hidden to a player initially and associated with a value and suit dealt to the player. The game enables the player to elect to display the associated value and suit. If the player exercises the option, the associated value and suit is displayed and a poker or blackjack evaluation is made based on the displayed associated value and suit. In various embodiments, the same associations are maintained for a single hand or play, multiple hands or plays or on a long term fixed basis. Associated symbols are also implemented with the game of slot.

Abstract: An apparatus for measuring the time delay between adjacent clock edges includes target and delay signal paths, a variable delay module in said delay signal path, the delay cell having a delay bias input, and a phase detector having respective inputs coupled to the target and delay signal paths. The variable delay module is operable to delay a first clock signal on the delay path so that a bias input signal presented to the delay bias input, when a bias input signal is present, corresponds to the time delay between the first clock signal and a second clock signal on the target signal path.

Abstract: A method of calibrating a timing vernier includes autocalibrating a plurality phase-delayed clock signal edges to match respective ideal signal edges, the phase-delayed clock signal edges dividing one period of a reference clock, comparing a vernier clock signal edge to one of the plurality of phase-delayed clock signal edges after the phase-delayed clock signal edges have been autocalibrated, and adjusting the vernier clock signal edge to match the one phase-delayed clock signal edge so that the clock edge is calibrated and available for calibrated use by a user.

Abstract: A method for autocalibrating a plurality of phase-delayed clock signal edges within a reference clock period includes measuring delay spacing between the plurality of clock signal edges, calculating programmed delay spacing, calculating ideal signal edges from the programmed delay spacing and adjusting the clock signal edges to match the respective ideal signal edges. A plurality of calibrated clock signal edges is produced that are selectively available to a user.
