摘要： Capacitors, including multilayer ceramic capacitors, may be subject to faults and failures that create short circuits between their dielectrics. Capacitors having fuses that protect the capacitors or the electrical devices using the capacitors when such faults occur are described herein. Embodiments include the presence of monolithic and non-monolithic structures including the fuse. Embodiments also include capacitors with multiple fuses that may prevent or mitigate capacitor failure. Methods for manufacturing and using the capacitors are also described.

摘要： At a processor of a camera-equipped electronic device, a first data set generated at a sensor incorporated within a camera module is obtained, and a second data set generated at one or more sensors external to the camera module is obtained. Based on the first set and second data sets, a first set of control signals is transmitted to the camera module. At a disturbance rejection controller integrated within the camera module, a second set of control signals is generated, based on the first set of control signals and on a third set of data obtained from the sensor incorporated within the camera module. The second set of control signals is transmitted to an actuator, which causes a displacement of a camera lens.

摘要： A multi-phase switch mode, voltage regulator has a transient mode portion in which a phase control output is coupled to one or more control inputs of one or more switch circuits that conduct inductor current through one or more transient phase inductors, from amongst a number of phase inductors. A slew mode control circuit detects a high slope and then a low slope in the feedback voltage and, in between detection of the high slope and the low slope, pulses the phase control output of the transient mode portion so that the switch circuit that conducts transient phase inductor current adds power to, or sinks power from, the power supply output. Other embodiments are also described.

摘要： In an embodiment, a system includes a power management unit (PMU), a non-volatile memory, a volatile memory, and a processor. The PMU may be configured to generate a power supply voltage, change a state of a status signal responsive to an event, and reduce a voltage level of the power supply voltage responsive to a predetermined period of time elapsing from detecting the event. The system may be configured to transition from a first to a second operating mode responsive to the change of the state of the status signal, and cancel pending commands to the non-volatile memory responsive to the transition to the second operating mode. The non-volatile memory may be configured to complete active commands prior the predetermined period of time elapsing.

摘要： In some implementations, a mobile device can be configured with virtual motion fences that delineate domains of motion detectable by the mobile device. In some implementations, the mobile device can be configured to invoke an application or function when the mobile device enters or exits a motion domain (by crossing a motion fence). In some implementations, entering or exiting a motion domain can cause components of the mobile device to power on or off (or awaken or sleep) in an incremental manner.

摘要： Interface circuits that may utilize a limited number of pins to detect a presence of an accessory, determine whether the accessory can provide or receive power, communicate with the accessory regarding at least that transfer of power, and transfer power accordingly. One example may provide detection circuitry for a host that may detect the presence of a pull-down resistor on a data pin of an accessory. The pull-down may indicate that a power consuming accessory has been connected. This example may detect the presence of power on a power pin. The presence of the power on the power pin may indicate that a power providing accessory has been connected.

摘要： Power and thermal management that uses trigger circuits to activate power telemetry. A power consumption level of a subsystem is monitored using a trigger circuit while power telemetry mode for the subsystem is inactive. When the monitored power consumption level exceeds a threshold, the trigger circuit activates the power telemetry mode of operation in which telemetry information of the subsystem is provided to a controller. Power consumption of the subsystem is then managed by the controller based on telemetry information obtained under the power telemetry mode. The controller can determine whether a power consumption level of the subsystem has dropped below a threshold, based on telemetry information obtained under the power telemetry mode. The controller may terminate the power telemetry mode when the power consumption level has dropped below the threshold. Other embodiments are also described and claimed.

摘要： An electronic device may include a conductor sensing assembly for sensing movement of a conductor, for example, in order to provide an input assembly that may be operative to detect a user's manipulation of a distance between the conductor and a portion of the conductor sensing assembly for controlling a functionality of the device. The conductor sensing assembly may include an oscillator that may produce oscillations that decay at different rates dependent upon a variable distance between a component of the conductor sensing assembly and a conductor of the input assembly. As the decay rate may be dependent on or otherwise correlate with the magnitude of a distance between the oscillator and a conductor, detection of the decay rate of the oscillator may enable determination of a state of a button input assembly that includes a conductor operative to be movable by a user with respect to the oscillator.

摘要： An accessory strobe device for a mobile device may operate to provide illumination at the same time as an internal built-in strobe (flash) of the mobile device. The accessory strobe device may receive a single, unidirectional signal from the mobile device that provides signals related to the timing of the internal strobe. The accessory strobe device may process the received signal to control its illumination using the timing and relative intensity levels of the internal strobe during metering and main (normal) flash operations associated with a camera on the mobile device. With the accessory strobe device operating using timing and relative intensity levels in a predetermined relationship with the timing and relative intensity levels of the internal strobe, the accessory strobe device may be used to complement the internal strobe during the metering and main (normal) flash operations for the camera.

摘要： Methods, circuits, and apparatus to distribute power among devices in an electronic system where a device may receive power from more than one source, may have a bidirectional power connector, or both. One example may resolve conflicts when an electronic device receives power from more than one source. In this example, the device may determine which source may provide the most power, and may select to receive power from the power source that may deliver the most power. Other examples may have a preference to receive power from a particular source or via a specific connector. Other examples may switch from receiving power over a first connector to providing power over the first connector, while others may receive and provide power over different connectors at the same time. Another may be connected to a battery, and may draw power from the battery or not depending on the type of battery.
