Abstract: A method (200) is provided for reducing stresses applied to one or more bonded interconnects (106) of a substrate (103) and a PCB (Printed Circuit Board) (104). The method comprises the steps of coupling (204) a compound (108) on a top surface of the substrate, wherein the compound has the property of expanding when a heat profile is applied thereto, coupling (206) a cover (102) to the PCB that overhangs at least a portion of the compound, and applying (208) the heat profile to the compound and optionally the cover and/or PCB. More than one apparatus implementing the method is also included.

Abstract: The invention concerns a method (200) and system (100) for charging a battery (110). The method includes the steps of receiving (212) an input power supply signal (300), monitoring (216) the input power supply signal to determine when the input power supply signal reaches first and second predetermined thresholds (314, 316) and in response to the monitoring step, selectively controlling (217) a charging switch (122) that controls the flow of the input power supply signal to the battery. The controlling step can include activating (220) the charging switch when the input power supply signal reaches the first predetermined threshold and deactivating (226) the switch when the input power supply signal reaches the second predetermined threshold.

Abstract: A portable electronic device and a method to protect the portable electronic device from a battery bounce are provided. The portable electronic device (100) can comprise a free-fall condition sensor (105) enabled to detect a pre-battery bounce condition in the portable electronic device and a processor (110) coupled to the free-fall condition sensor (105). The processor (110), in response to a detection of the pre-battery bounce condition by the free-fall condition sensor (105), can be programmed to place the portable electronic device (100) in a pre-battery bounce setting. The method can include detecting a pre-battery bounce condition in the portable electronic device (405) and in response to the detection of the pre-battery bounce condition (405), placing the portable electronic device in a pre-battery bounce setting (410).
