An electrical waveform generator for driving an electromechanical load includes a digital signal processor connected to a waveform generator component in turn connected to an amplifier section with a filter network, the latter being connected to sensing and conditioning circuit componentry that is in turn connected to analog-to-digital converter circuitry. A digital memory stores digitized voltage and current waveform information. The processor determines a phase difference between voltage and current waveforms, compares the determined phase difference to a phase difference command and generates a phase error or correction signal. The processor also generates an amplitude error signal for inducing the amplifier section to change its output amplitude to result in a predetermined amplitude error level for a respective one of the voltage and current waveforms.

A connection broker (44), located between lower-level system entities (16, 58, 264) associated with a narrowband-broadband interface (250) and a call server (18) that controls call connection across the narrowband-broadband network, contains a memory (251) that stores connection-related information and protocol converters. The connection broker (44) accesses the protocol converters to interpret control messages received from the call server (18) and, where necessary, transposes messages for the call server into a standardised format for use over a uniform fabric application interface (66). Control messages pertaining to connection paths within the narrowband-broadband network (250) and relayed via the connection broker (44) are appropriately phrased (by the connection-related information and protocol converters) to ensure that meaningful information and instruction is communicated between the call server (18) and the lower-level system entities (16, 58, 264). Use of the protocol converters therefore enables connection attributes and network operation and configuration to be altered and advised in-call by having the connection broker (44) both change connection-related information and communicate any change in network configuration to the call server and lower-level system entities, as appropriate.

Access control for each part in an HTML document constituting a Web page is performed according to the origin of the part in the document. Thereby, a content provided by a malicious user or server is prevented from fraudulently reading and writing other parts in the HTML document. More precisely, on a server side, each content (including a JavaScript program) is automatically provided with a label indicating the domain that is the origin of the content. Thereby, the control of accesses to multiple domains (cross domain access control) can be performed on a client side. Under this configuration, a combination of the contents, metadata and the access control policy is transmitted from the server side to the client side.

An improved rocker-type switch has a toggle member pivotably mounted on a central pivot member in a frame of a top housing part joined to a bottom housing part holding switch contacts in a modular block subassembly. A pair of movable contact arms is actuated by spring-biased actuator members held in the central pivot member. The modular block subassembly has an insulative top block member, a top switch contact plate with switch contacts on upright tabs inserted through slots in the top block member, an insulative bottom block member sandwiching the top switch contact plate, and a bottom switch contact plate having switch contacts on upright tabs inserted through slots in the bottom and top block members, forming a pair of opposing switch contact positions for the movable contact arms. The switch contact plates have clip portions for inserting the tabs of respective switch contact terminal plates therein. For different switch configurations, e.g., single-pole, double-pole, 3-way, or 4-way operation, the switch contact plates are changed, but the same block subassembly and other parts can be used, thereby minimizing change of the surrounding parts, limiting insulative molding costs, eliminating tolerance stack-up, and facilitating assembly through automation.

A program operation in a non-volatile memory is segmented at predefined junctures into smaller segments for execution over different times. The predefined junctures are such that they allow unambiguous identification when restarting the operation in a next segment so that the operation can continue without having to restart from the very beginning of the operation. This is accomplished by requiring the programming sequence of each segment to be atomic, that is, to only terminate at a predetermined type of programming step. In a next segment, the terminating programming step is identified by detecting a predetermined pattern of ECC errors across a group of programmed wordlines.
