Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a complex controller by controlling a micro actuator that is connected to a positioning arm so that it can be rotated according to a position error signal(PES) and controlling the controlling of a voice coil motor according to the sum of the PES and a relative positional signal for reflecting the position of the actuator regarding the arm. SOLUTION: In a first addition node 30, a positional signal (y) of a read/write head that is fitted to a micro actuator 20 is subtracted from a reference track signal (r) to generate a head position error signal(PES) e2 for indicating a tracking error. The actuator 20 is moved to a position y2 that is relative to the arm by a first control signal u2 based on the PES e2. In a second addition node 34, the PES e2 is added to the relative position signal y2 to generate a motor error signal e1. The motor 10 moves an arm 12 to a position y1 that is relative to the motor 10 according to the second control signal u1 based on the motor error signal e1.

Abstract: PROBLEM TO BE SOLVED: To provide a method for permitting a client to speedily and efficiently access a function installed in a server interface. SOLUTION: The method for managing client server communication is provided. The function and an interface method are supplied to a server with the method. Reference to the interface method is provided to the client and the request of the client is processed by invoking the interface method on the server via reference. Ideally, the interface method is implemented by providing the server with the table of a pointer to the function and providing the client with reference to the table of the pointer.

Abstract: PROBLEM TO BE SOLVED: To provide a system and a method that specify and manage a mode of connection of a broadband cable modem network station to a network. SOLUTION: This system has a state drive type network manager that has functions such as a central error processing state, initialization, dynamic host configuration, configuration download, start simple network management and peripheral state to an operating state. In the operating state, an error and other messages communicated from the other state are monitored, an error message is set to the central type error processing state, and a message is requested to an operation support system interface management task. The error processing state receives the error message and requests an error event logging from an operation support system interface management task. A revision upper-stream or downstream channel task optimizes channel selection.

Abstract: PROBLEM TO BE SOLVED: To provide an enhanced cable modem link layer bridge. SOLUTION: The cable modem link layer bridge includes a downstream transfer task and an upstream transfer task. The downstream transfer task is configured to receive a 1st message from a cable network and transfer the 1st message to equipment (CPE) at customer's premises. The upstream transfer task is configured to receive a 2nd message from the CPE and transfer the 2nd message to the cable network, and multi-task processing is applied to the upstream transfer task and the downstream transfer task so that the upstream transfer task transfers the 2nd message, while the downstream transfer task transfers the 1st message.

Abstract: A network station subsystem architecture that uses a simplified interface reference discovery method and system is provided. In one embodiment a method for managing client-server communications is disclosed that includes providing a server with functions and interface methods; providing a client with references to the interface methods; and processing client requests by invoking the interface methods on the server via the references. Ideally, the interface methods are implemented by providing the server with a table of pointers to the functions, and providing the client with references to the table of pointers, ideally at the time of design. In another embodiment, a system for managing communications in a network station for a data-over-cable network having a plurality of network stations is provided. The system includes a plurality of components in the network station, each of the plurality of components having a functionality set and a table of pointers for the functionality set; a station manager having references to the tables of pointers in the plurality of components; and an interface manager for communication with the plurality of components and the station manager, the interface manager configured to process station manager requests for functionality from the components through the interface manager via the references to the tables of pointers.
