Abstract: An electronic device, with a touch-sensitive surface and a display, includes one or more sensors to detect intensity of contacts with the touch-sensitive surface. The device detects a contact on the touch-sensitive surface while a focus selector corresponding to the contact is at a respective location on the display associated with additional information not initially displayed on the display. While the focus selector is at the respective location, upon determining that the contact has an intensity above a respective intensity threshold before a predefined delay time has elapsed with the focus selector at the respective location, the device displays the additional information associated with the respective location without waiting until the predefined delay time has elapsed; and upon determining that the contact has an intensity below the respective intensity threshold, the device waits until the predefined delay time has elapsed to display the additional information associated with the respective location.

Abstract: An electronic device with a display, a touch-sensitive surface, and sensors to detect intensity of contacts with the touch-sensitive surface displays, on the display, an affordance corresponding to respective content at a respective size and detects a gesture that includes an increase in intensity of a contact followed by a subsequent decrease in intensity of the contact. In response to the increase in intensity, the device decreases a size of the affordance below the respective size. In response to the subsequent decrease in intensity: when a maximum intensity of the contact is above a content-display intensity threshold, the device ceases to display the affordance and displays at least a portion of the respective content; and when a maximum intensity of the contact is below the content-display intensity threshold, the device increases the size of the affordance to the respective size and forgoes displaying the respective content.

Abstract: An electronic device with a display, a touch-sensitive surface and one or more sensors to detect intensity of contacts with the touch-sensitive surface displays a respective control icon with simulated three-dimensional characteristics and a cursor over the respective control icon. The device detects, on the touch-sensitive surface, a stationary press input that includes an increase in intensity of a contact that corresponds to the cursor. In response to detecting the stationary press input, the device changes an appearance of the respective control icon in accordance with the simulated three-dimensional characteristics of the control icon and moves the cursor laterally on the display in accordance with the change in appearance of the respective control icon.

Abstract: An electronic device with a touch-sensitive surface, a display, and one or more sensors to detect intensity of contacts, detects a contact, determines a location and intensity of the contact on the touch-sensitive surface, and displays a response, the response being based at least in part on an input-output mapping of intensity to response at the contact location. The input-output mapping including a first input-output relationship between intensity and response over a first range of intensity values, a second input-output relationship between intensity and response over a second range of intensity values, and a transitional intensity value where the first range of intensity values meets or overlaps the second range of intensity values. At the transitional intensity value, the first input-output relationship has a first rate of change, the second input-output relationship has a second rate of change, and the first rate is substantially the same as the second rate.

Abstract: An electronic device displays a user interface in a first display state. The device detects a first portion of a gesture on a touch-sensitive surface, including detecting intensity of a respective contact of the gesture. In response to detecting the first portion of the gesture, the device displays an intermediate display state between the first display state and a second display state. In response to detecting the end of the gesture: if intensity of the respective contact had reached a predefined intensity threshold prior to the end of the gesture, the device displays the second display state; otherwise, the device redisplays the first display state. After displaying an animated transition between a first display state and a second state, the device, optionally, detects an increase of the contact intensity. In response, the device displays a continuation of the animation in accordance with the increasing intensity of the respective contact.

Abstract: Methods and systems related to interfaces for interacting with a digital assistant in a desktop environment are disclosed. In some embodiments, a digital assistant is invoked on a user device by a gesture following a predetermined motion pattern on a touch-sensitive surface of the user device. In some embodiments, a user device selectively invokes a dictation mode or a command mode to process a speech input depending on whether an input focus of the user device is within a text input area displayed on the user device. In some embodiments, a digital assistant performs various operations in response to one or more objects being dragged and dropped onto an iconic representation of the digital assistant displayed on a graphical user interface. In some embodiments, a digital assistant is invoked to cooperate with the user to complete a task that the user has already started on a user device.

Abstract: The invention provides a novel method for controlling the oxidant injection to a reactor by determining fluctuations in the requirements from monitoring the flow rates and pressures of an upstream reactor. The method is used to oxidize carbon monoxide in a hydrogen-rich reformate stream supplied to a fuel cell.

Abstract: A method for controlling the power and temperature and fuel source of a combustor in a fuel cell apparatus to supply heat to a fuel processor where the combustor has dual fuel inlet streams including a first fuel stream, and a second fuel stream of anode effluent from the fuel cell and reformate from the fuel processor. In all operating modes, an enthalpy balance is determined by regulating the amount of the first and/or second fuel streams and the quantity of the first air flow stream to support fuel processor power requirements.

Abstract: A foldable knife is provided having two lock blades each of which or both of which simultaneously may be locked in their open position against movement in either direction about their respective pivots. A separate locking member and tumbler is provided for each blade but only a single spring is utilized to operate both locking members and urge them toward their locked position.
