Abstract: A lithium ion battery comprises a shell, a cell disposed in the shell, and two lugs connected to the cell. Each of the lugs comprises a conductive foil with a surface and a PTC layer disposed on the surface of the conductive foil. The lugs conduct currents between the lithium ion battery and an outer circuit.

Abstract: The present invention discloses a group of histone deacetylase inhibitors and use thereof. The histone deacetylase inhibitors are useful in the treatment of malignant tumors and the diseases associated with differentiation and proliferation.

Abstract: A portable electronic device includes a housing, at least one thermoscope unit mounted on the housing, a processor unit connected to the thermscope unit, and at least one light emitting unit connected to the processor unit. The processor unit stores data of predetermined different light colors corresponding to different ambient temperature ranges. The thermoscope unit detects ambient temperature, the processor unit obtains the ambient temperature from the thermoscope unit and controls the light emitting unit to emit light in predetermined colors corresponding to the ambient temperature range according to the stored data.

Abstract: A method, apparatus and computer program product are provided for providing power consumption notification and management. More particularly, application power consumption models and device battery energy levels can be used to determine a device discharge duration. A device power consumption rate can be determined from application power consumption models.

Abstract: Event triggered snapshots of display content of software applications facilitate for a user, typically in the role of a software application developer, in the process of power-optimising an application under development. The invention provides the developers with an ability to correlate specific software application events, e.g. user interface events, to power consumption peaks and lows.
