Abstract:
A power management method for an electronic apparatus powered by a battery unit and installed with an operating system includes the steps of inputting a user-defined remaining capacity for the battery unit into the electronic apparatus, and reporting the user-defined remaining capacity to the operating system. The operating system supports a power management specification and is operable so as to obtain an actual remaining capacity of the battery unit. When the operating system compares the user-defined remaining capacity with a reference value according to the power management specification, and determines the user-defined remaining capacity to be lower than the reference value, the operating system enables operation of the electronic apparatus in a low power consumption mode.
Abstract:
A portable electronic device includes a base module with a housing defining upper and lower sliding grooves at each of two opposite side walls of the housing, and a system module mounted slidably on the base module through a pair of sliding units. Each of the sliding units includes an upper rolling member that is received in the upper sliding groove and that is in rolling contact with a respective one of the side walls, and a lower rolling member that is received in the lower sliding groove and that is in rolling contact with a respective one of the side walls.
Abstract:
A method for acquiring information is implemented in a hand-held mobile communications device to access information in a remote information server through the Internet. The method includes enabling the communications device to acquire information from the information server at predetermined times, to filter the acquired information according to a filtering rule, and to display information complying with the filtering rule or a notification message relating to the information complying with the filtering rule according to a user setting. The method and device permits user convenience and ensures information confidentiality, without incurring extra fees.
Abstract:
A power supply system for supplying power to a load of an electronic apparatus includes first and second battery units, and a selector coupled to the load and the first and second battery units. The selector is operable so as to break electrical connection between the second battery unit and the load and to simultaneously make electrical connection between the first battery unit and the load when a remaining capacity of the first battery unit is higher than a predetermined reference value, and so as to break electrical connection between the first battery unit and the load and to simultaneously make electrical connection between the second battery unit and the load when the remaining capacity of the first battery unit is lower than the predetermined reference value. A controller coupled to the selector, is responsive to a first control command, which may be issued by the electronic apparatus, so that the controller overrides the detector and enables operation of the selector in the first state.
Abstract:
A portable electronic apparatus includes first and second modules, and a control unit. The first module includes a first charging circuit to be coupled to a first power source, and a first battery unit coupled to the first charging circuit. The second module is connected removably to the first module, and includes a second charging circuit to be coupled to a second power source, and a second battery unit coupled to the second charging circuit. The control unit enables the first and second battery units to be charged independently and respectively through the first and second charging circuits using the first and second power sources when the second module is disconnected from the first module, and enables the first and second battery units to be charged through the first charging circuit using the first power source when the second module is connected to the first module.

Abstract:
A wireless interface device includes a display that can interface with a host computer in a stand-alone configuration or a host computer connected in either a wired or wireless local area network (LAN). Once connected to a host computer, the wireless interface device takes control of the host and displays anything that is being displayed on the host.
Abstract:
A method for acquiring information is implemented in a hand-held mobile communications device to access information in a remote information server through the Internet. The method includes enabling the communications device to acquire partial content of information from the information server at predetermined times, to filter the acquired partial content according to a filtering rule, download information that complies with the filtering rule according to the filtering result, and to display the information complying with the filtering rule or a notification message relating to the information complying with the filtering rule according to a user setting. The method and device permit user convenience and ensure information confidentiality, without incurring extra fees.
