    摘要： A mobile device is described herein in which the mobile device has a housing that includes a transition point and an actuator that can be flexible and that can be used to initiate a predetermined action. The actuator can include a transition point. The mobile device can also have a stiffening component that can be configured to engage the actuator and can also have a flexible circuit. In one arrangement, the flexible circuit can be coupled to the stiffening component and the flexible circuit can be configured to relay signals in response to a force being applied to the actuator. In another arrangement, the actuator can be positioned such that the transition point of the actuator substantially aligns with the transition point of the housing of the mobile device.

    摘要： A switching mode power supply (SMPS) includes a transformer having a primary winding, a secondary winding for providing an output voltage, and an auxiliary winding. The SMPS also includes a power switch coupled to the primary winding. A first control circuit is coupled to the secondary winding, and is configured to provide a first electrical signal to the secondary winding when the output voltage of the SMPS is less than a reference voltage during a discontinuous time, whereupon a second electrical signal is induced in the auxiliary winding. A second control circuit is coupled to the auxiliary winding and the power switch. The second control circuit is configured to regulate the output of the SMPS by controlling the power switch in response to a feedback voltage signal from the auxiliary winding, and is further configured to turn on the power switch in response to the second electrical signal.

    摘要： A mobile electronic device has a dome switch assembly secured to the housing of the device, over a recess formed in the housing of device. The dome switch assembly has a substrate with a vent hole communicating between the recess of the housing and the space comprised between the substrate and a dome actuation portion of the dome switch assembly. Upon actuation of the dome switch assembly, air present between the dome actuation portion and the substrate flows into the recess of the housing.
