摘要:
A multi-node time division multiplexing (TDM) system is disclosed. The improved method and apparatus utilizes an asynchronous synchronization packet (ASP) to synchronize the timing in all the nodes of the system. In some embodiments, the ASP also maps the time slots in a data frame to particular nodes. The ASP is sent at the start of each data frame to all the nodes in the system and each node synchronizes itself to the time of receipt of the ASP, thus establishing frame-based timing for all the nodes. Additionally, the ASP can contain a table that maps the data frame time slots to the nodes in the system.
摘要:
We describe an apparatus including a plurality of sensing elements, a conductive layer, and a compressive layer interposed between the plurality of sensing elements and the conductive layer. The conductive layer can include a plurality of segments. A user applies a force to an actuator positioned over the conductive layer. The actuator changes a capacitance of at least one capacitor formed by at least one of the plurality of sensing elements, the conductive layer (at least one segment), and the compressive layer by reducing the distance between the at least one of the plurality of sensing elements and the conductive layer responsive to the applied force. The device measures and calculates a magnitude and direction of the force by measuring the change in the capacitance.

The present invention includes systems and methods for customization of internet applications. Multiple levels of customization are applied to both static and functional aspects of user interface elements including, for example, tab-order, tab-over, immediate access keys, and hotkeys. Customization is also achieved with respect to searching over multiple user interfaces, presentation of information on a user interface, and the interaction model used by the internet application. Customization is enabled on any client supporting standard browser functionality.

摘要:
A therapeutic foam for the treatment of, inter alia, varicose veins comprises a sclerosing solution foamed with a physiological gas such as carbon dioxide, oxygen or a mixture thereof. The foam has a nitrogen content of less than 0.8%. It may be generated using a pressurised canister system incorporating a fine mesh of micron dimensions through which the gas and sclerosing liquid are passed to make the foam. Alternatively, the foam may be generated by passing gas and solution between two syringes through a fine mesh. Techniques are described for minimising the amount of nitrogen in a canister or syringe based product. A technique for generating and delivering foam simultaneously using a syringe based device is also disclosed.
摘要:
An improved key matrix scanning technique conducts a first pre-scan on a first array of connections in a key matrix to identify any activated keys or buttons associated with the first array. A second sub-scan is conducted on a second array of connections in the key matrix but only for the connections in the first array that are detected as having activated keys.
