Abstract: A first input to a mobile device indicates a first navigation destination at a first level of specificity. The mobile device initiates navigation towards a first location corresponding to the first navigation destination. While navigation towards the first location corresponding to the first navigation destination is ongoing and before reaching the first location, in accordance with a determination that one or more first criteria are satisfied, the mobile device prompts for an input for determination a second location corresponding to a second navigation destination with a second level of specificity, the second level of specificity more specific than the first level of specificity. The mobile device receives a second input in response to the prompt. In accordance with a determination that the second input satisfies one or more second criteria, the mobile device initiates navigation towards the second location corresponding to the second navigation destination.

Abstract: Notifications for instructing user behavior can be determined and presented when appropriate. Current fitness data are accessed. This data is used to determine whether a user fitness goal is likely to be achieved. If not, a notification may be determined and presented at a user device.

Abstract: Utilization of a diode in the input of the vertical deflection drive amplifier serves to render the amplifier insensitive to power supply variation and shortens the response time of the amplifier to changes in the vertical centering circuit. In one embodiment the diode is connected in series with the variable terminal of the centering potentiometer in the input of the vertical drive amplifier. In a second embodiment, wherein the vertical deflection drive amplifier includes a differential amplifier, the diode is connected to one input of the amplifier and the centering circuit is connected to the second input of the amplifier. In both embodiments the diode forms part of a time constant circuit which controls the linearity of the sweep signal applied to the input of the amplifier and also controls the response time of the amplifier to DC voltage level change.
