摘要:
A hybrid power supply used in a device generally includes a fuel cell plant configured to produce a DC voltage via electrochemical conversion of a fuel, a fuel reservoir attached to the fuel cell plant for supplying the fuel to the fuel cell plant, and a rechargeable battery electrically coupled to the fuel cell plant. The fuel cell plant keeps rechargeable battery substantially charged while rechargeable battery accommodates load variations resulting from operation of the device. In this way, the hybrid power supply maintains operation of the device when the fuel reservoir is removed.

A power source management system disposed within a device is configured to communicate with a power source and perform an authentication procedure to determine whether the power source is an approved power source. The authentication procedure may involve the use of a challenge-response procedure using keys resident in the device and the power source. If it is determined that the power source is not an approved power source, the power source management system prevents use of or disables certain functionality of the device.

A rechargeable battery includes a housing having an external surface including a user interface region. A battery cell within the housing is characterized by a charging status, a state of charge, and a state of health. A processor disposed within the housing determines and/or stores the charging status as well as one or more of the state of charge and the state of health of the battery cell. The user interface region provides a plurality of visual components configured to provide a plurality of visual cues relating to the charging status, the state of charge, and the state of health of the battery cell. The plurality of visual components may include a persistent display, an on-demand display, and an input component. The input component may be used to select the manner in which the visual cues are provided.

Described is a method of supplying power to recharge a battery and drive at least one load separate from the battery, wherein the load is connected to the battery. A current amount supplied to only the battery is determined. A battery voltage is determined. Power is disabled to the battery when the current amount is less than a predetermined current termination threshold and the battery voltage is greater than or equal to a voltage limit.

Under the present invention, an enterprise application and corresponding client properties file is provided on a mobile device. Upon initiation of the mobile device, the client properties file is read into application memory. The user can then make modifications to the client properties file to change the user settings as he/she desires. If an updated properties file is later received from the server, it is reconciled with the client properties file. Thus, the user's modifications are not discarded or overwritten. In addition, the reconciled properties file could be synchronized to the server so that if the mobile device is lost or fails, the user's settings can be restored.

Methods, systems, and apparatuses for charging a battery in a mobile device are described. In embodiments described herein a power supply voltage and/or a power supply current of a power supply coupled to charger of the mobile is reduced. The reduction in power supply voltage and/or current results in a reduction in heat dissipation and power dissipation by the charger.
摘要:
Described is a method wherein a computer terminal is coupled to a power supply through a docking arrangement. The docking arrangement includes a protection circuit. A current supplied to the computing terminal is detected. When the current is greater than a predetermined value, the computer terminal is decoupled from the power supply. After the computer terminal is decoupled from the power supply, the computer terminal is recoupled to the power supply, and the method repeats beginning with detecting the current supplied to the computing terminal.
摘要:
A method, system and apparatus for synchronization queue management. A synchronization queue management system can include a connection manager programmed to establish a synchronization link between a host pervasive device and a synchronization partner platform. The system further can include a link quality analysis service programmed to indicate a link quality for an established synchronization link. Finally, the system can include a synchronization application coupled to the connection manager and the link quality analysis service. The synchronization application can be configured to synchronize data in a synchronization queue in the host pervasive device with the synchronization partner platform over the established synchronization link. The synchronization application further can be configured to manage the synchronization queue based upon a link quality indicated by the link quality analysis service. Preferably, the link quality can be a throughput measurement or a usage cost measurement.

A method, system, and computer program product for displaying and navigating a tree. The method comprises: selecting a node on a level of the tree, wherein the node has a number of child nodes on a next level of the tree; determining if the number of child nodes of the selected node exceeds a predetermined level maximum number of child nodes; and, if the number of child nodes of the selected node exceeds the predetermined level maximum number of child nodes, displaying a single subset of the child nodes and at least one selectable affordance for displaying another subset of the child nodes.
摘要:
A computer-implementable method, system, and computer-usable medium designed to move data from a source file to multiple target documents by inserting a copy of an insertion point into each of multiple target files; associating specific source data, from a source file, with the insertion point; and pasting the specific source data into the insertion points that have been inserted into each of the multiple target files.
