摘要:
Systems and methods for changing items of a computer file, such as an archive file, can include an application programmed to create a file including a first item and a second item, the application storing the file on a storage medium. Systems can also include an input/output module associated with the application, the input/output module retiring the first item upon a change to the first item resulting in an increase or a decrease in a size of the first item. Upon retiring the first item, the input/output module can write a third item at an end of the file, the third item including the change to the first item. Methods can include retiring the first item upon a change to the first item, and writing a third item after the second item, the third item including the change to the first item.

Systems and methods for changing items of a computer file can include a storage medium, and an application programmed to create a file including a first item and a second item, the application storing the file on the storage medium, and the first item including padding. The system can also include an input/output module associated with the application, the input/output module being programmed to use at least a portion of the padding of the first item to accommodate a change in a size of the first item. A method can include providing a file including at least a first item and a second item, the first item including padding, changing the first item, and using at least a portion of the padding of the first item to accommodate a change in a size of the first item.

Migrating a chat messaging service provided for a chat user is disclosed. At a second chat server from a first chat server, static information associated with a chat user is received. The static information is received before the chat user is indicated as being associated with a migration state. At the second chat server from the first chat server, dynamic information associated with the chat user is received. At least a portion of the dynamic information is received after the chat user is indicated as being associated with the migration state. After the chat user is no longer indicated as being associated with the migration state, a chat message for the chat user is received at the second chat server.
摘要:
In an online conference session involving a presenter at an endpoint device and a plurality of attendees at respective endpoint devices, screenshots of content displayed at the endpoint device of the presenter and content displayed at the endpoint devices of each of the attendees are captured on a periodic basis. First data is stored that represents screenshots of content displayed at the endpoint device of the presenter and of content displayed at the endpoint devices of each of the attendees for each screenshot capture instance. Second data is stored that represents captured screenshots at each of a plurality of screenshot capture instances at the endpoint device for each attendee during the conference session. An attention metric is generated for one or more attendees based on the first data and second data.

The claimed subject matter provides a method for publishing location information. The method includes receiving the location information from an entity. The entity may be associated with a geographic location. The method further includes identifying one or more entities to be notified of the location information. Additionally, the method includes sending the location information to the identified entities.
摘要:
A battery charger with a discrete switched regulator provides relatively high efficiency and relatively low cost. Unlike known battery chargers which incorporate switched regulator ICs, the battery charger in accordance with the present invention utilizes the microprocessor for a dual function. In particular, the microprocessor not only controls the charging characteristics of the battery charging circuit but also directly controls the power output of the battery charger by direct control of the discrete switched regulator circuit. By using a discrete switched regulator circuit and redefining the role of the microprocessor, the battery charger in accordance with the present invention is relatively less expensive than known battery chargers which incorporate switched regulator ICs.

Described are a method and apparatus for charging an electric vehicle powered by ultracapacitors. The vehicle includes a current collector device for collecting power from an external power source, an electric motor module for providing a driving force to the vehicle, an ultracapacitor module, and a charger device. The ultracapacitor module includes one or more ultracapacitors. The ultracapacitor module is coupled to the current collector device for receiving power and is coupled to the electric motor module for providing power. The charger device is connected to the current collector, the ultracapacitor module, and to a temperature signal associated with one or more of the one or more ultracapacitors. The charger device is configured to adjust power supplied to the ultracapacitor module based on the temperature signal.

The present invention relates to a preparation method of a long cycle life negative electrode as well as the organic hybrid capacitor battery using this negative electrode. The preparation steps of the negative electrode include: blending all materials including carbon material with a fast lithium intercalation capability, and a binder, and adding in solvent; pressing the blended material to get an electrode plate of a certain thickness; stirring the conductive agent to a paste, and attaching it to a cathode current collector; attaching the electrode plate to the conductive agent coated negative current collector; Drying, grinding, cutting and vacuum drying to form a negative electrode. In the present invention, the process of pressing the electrode plate into shape first and then attaching to the negative current collector is used, which enables the negative electrode to have a high compressed density and cycle life. The organic hybrid super capacitor battery in the present invention has high energy density (up to 45-80 Wh/Kg), high power density (>4500 W/Kg), and can be widely used in electric vehicles, power tools, solar energy storage, wind energy storage, portable electric appliances and other fields.
