Abstract: Disclosed herein are systems and methods that allow activation of and intuitive interactions with a companion-display mode for an electronic device. In one aspect, a first device receives a request to annotate content on the first device. In accordance with a determination that a second device is available for displaying the content in an annotation mode and has not been previously approved to display the content in the annotation mode, the first device displays a selectable option that, when selected, causes the first device to send an instruction to display the content in the annotation mode at the second device. When the electronic device is available for displaying the content in the annotation mode and has previously been approved to display the content in the annotation mode, the first device sends an instruction to the second device to display the content in the annotation mode automatically without further user intervention.

The method also includes that in response to detecting the input, and while continuing to display the user interface, concurrently displaying on the display: a first selectable option for changing the display property of the user interface on the display of the first electronic device, and a second selectable option for requesting display at a second electronic device, distinct from the first electronic device, of a user interface that includes content from the user interface.

Abstract: A method and popping machine for popping different types of popcorn kernels is provided, where the different types of popcorn kernels include at least mushroom type popcorn and butterfly type popcorn. The method includes determining a selected one of the different types of popcorn kernels to be popped in a first popping cycle based upon a selection made by an operator, and then retrieving and using a first set of predetermined cooking temperature set points associated with cooking the selected one of the different types of popcorn kernels during performance of the first popping cycle. The cooking temperature set points determine several items which may include when to heat a kettle of the popping machine, when to signal an operator to take action such as loading kernels or dumping popped popcorn, and when to add sugar if a sweetened popped popcorn type is desired.

Abstract: An extremum-seeking control system for formation flight that uses blended performance parameters in a conglomerate performance function that better approximates drag reduction than performance functions formed from individual measurements. Generally, a variety of different measurements are taken and fed to a control system, the measurements are weighted, and are then subjected to a peak-seeking control algorithm. As measurements are continually taken, the aircraft will be guided to a relative position which optimizes the drag reduction of the formation. Two embodiments are discussed. Two approaches are shown for determining relative weightings: “a priori” by which they are qualitatively determined (by minimizing the error between the conglomerate function and the drag reduction function), and by periodically updating the weightings as the formation evolves.

Abstract: A popcorn popping assembly includes a popcorn popping kettle having a side wall extending from a bottom wall. The assembly includes a plurality of retainers. Each of the retainers includes a bottom wall extending between a pair of side walls. The side walls and the bottom wall define a cavity, and an aperture is formed in the bottom wall and defines an essentially closed shaped periphery. The assembly includes a plurality of studs, each configured to be inserted through a respective aperture of a respective retainer. A plurality of fasteners are each configured to be received within the cavity of a retainer and couple with a stud to secure the stud to the retainer. A temperature sensor may extend through at least one of the apertures. A stud may be configured to cooperate with the temperature sensor and hold the temperature sensor in a predetermined location.

The methods include monitoring a power signal to the portion of the cooking appliance, including monitoring a current and/or voltage of the power signal. The methods also include selectively interrupting power to the portion of the cooking appliance in response to: determining that the current fails to exceed a current threshold within a time threshold, determining that the voltage fails to exceed a voltage threshold within a time threshold, determining that the current exceeds a current threshold for a first time threshold but fails to exceed the current threshold for a second time threshold, and determining that the voltage exceeds a voltage threshold for a first time threshold but fails to exceed the voltage threshold for a second time threshold. The methods also include temperature sensing and controlling the power signal based thereupon.

Abstract: A computerized system and method for peak-seeking-control that uses a unique Kalman filter design to optimize a control loop, in real time, to either maximize or minimize a performance function of a physical object (“plant”). The system and method achieves more accurate and efficient peak-seeking-control by using a time-varying Kalman filter to estimate both the performance function gradient (slope) and Hessian (curvature) based on direct position measurements of the plant, and does not rely upon modeling the plant response to persistent excitation. The system and method can be naturally applied in various applications in which plant performance functions have multiple independent parameters, and it does not depend upon frequency separation to distinguish between system dimensions.

A heat control system is provided having a selector switch for selecting one of multiple rates of heat to be delivered to the kettle. An oil delivery system is coupled to the selector switch for selecting one of varying amounts of oil to be delivered to the kettle in conjunction with selecting the rate or amount of heat to be delivered to the kettle.

Abstract: Within a cotton candy machine a delay-on-break delay timer is used to delay the de-energization of the spinner-head motor for a predetermined period of time after the heater elements are turned off. Thus, while the heater elements are cooling down, the motor and spinner head continue to rotate. Once the heater elements are cooled to the point where they cannot melt or burn the sugar, then the motor can be de-energized and the spinner head allowed to stop.
