    摘要: A triac dimmable compact fluorescent lamp including a power feedback circuit. The power feedback circuit helps to maintain the level of current drawn from the triac to at least the level of the triac holding current especially during low dim levels. In one preferred embodiment, the feedback circuit is fed into a junction joining together a pair of fast recovery diodes for converting the high frequency square wave signal into a unidirectional signal supplied to an inverter. Overboost voltages across a buffer capacitor are minimized during low dim levels.

    摘要: A dimmable fluorescent lamp including a feedback circuit for drawing sufficient current to maintain an appropriate charge across the buffer capacitor. A bypass capacitor provides a path for diverting a portion of the power which would otherwise be fed back to the buffer capacitor during low level dimming. Consequently, overboost voltages across the buffer capacitor during low level dimming are substantially reduced.

    摘要: A circuit for processing a jump operation also enables handling pending interrupts or exceptions. The jump operation has an operand specifying a destination address. If an interrupt or exception is pending, a destination program counter is set to the contents of the operand. Then the program counter is set to an interrupt or exception handler address. If no interrupt or exception is pending, then the program counter is set to the destination address.

    摘要: A lock detector for a phase locked loop circuit, wherein an oscillator is controlled by a control signal produced by comparing the output signal of the oscillator to a reference signal. The lock detector samples the control signal, examines a plurality of samples according to criteria associated with a prescribed lock condition between the reference signal and the oscillator output signal, and generates a lock signal indicative of the lock condition being met if the samples satisfy the criteria. In a favorable embodiment, the lock detector forms a first group of samples sampled at a rate controlled by the reference signal and a second group of samples sampled at a rate controlled by the oscillator output signal. The samples are stored and shifted at the respective rates in respective shift registers. The contents of each stage of the shift registers are then examined according to a logic function. In an embodiment, the control signal includes first and second commands and is subjected to an initial logic function whose output is sampled by the shift registers.

    摘要: A control system comprises multiple consumer electronics devices and task-driven control means coupled to the devices for controlling an interaction among the devices. The control means acts on respective software representations of each respective one of the consumer devices. By encapsulating the variable complexity of the task within a software representation, it can be made as simple or as sophisticated as needed to bring the capabilities up to a common level. Since the level of interface is common to the devices, applications can uniformly manipulate devices which embody very different levels of sophistication.

    摘要: A decision support system for the management of an agile supply chain that provides an architecture including a server side and a client side. The server side includes a decision support system database that interfaces with a model engine that performs analysis of the data to support planning decisions. The server side includes a server manager that coordinates requests for service and information. The client side includes decision frames that present the various view points available in the system to the users. A frame manager coordinates the requests from decision support frames to access the needed data and models. The decision support frames provide a view into the supply chain and integrate analytical models responsive to the view point of a business process such as demand management. The frames include a supply management frame, a demand management frame, a vendor managed replenishment frame, a Planning, Sales and Inventory planning frame, and a distribution network design frame. The frame manager includes a system integrator and a functional integrator. A database management system manages the supply and maintenance of information needed by the modeling processes through the frame manager. A domain management process limits data available to saidl frame responsive to a user selection. The system also includes a demand and supply reconciliation process; a capacity planning process; a vendor managed replenishment process; and a scenario management process.

    摘要: A user interface for a full-text document retrieval computerized system comprises a display with a words window in which each query word is displayed by means of a distinctive representation uniquely associated with each displayed word. In a subsequent results window, each document header or title or representation is accompanied by an indicator which employs the same distinctive representation to directly indicate to the user the relative contributions of the individual query words to each listed document. In a preferred embodiment, the distinctive representation is integrated with an associated weight first indicator in a words window, and in the results window the distinctive representations are also integrated with an associated weight second indicator. The distinctive representation can take several forms, such as by a different color or by means of hatching or shading or by displayed icons.

    摘要: A ballast for powering a high intensity discharge lamp including an ignitor and a resonant circuit. Ignition pulses produced by the ignitor are added to a boosted low frequency voltage produced by the circuit operating near its resonant frequency during start up of the lamp. The circuit is disabled after a predetermined period of time has elapsed following ignition of the lamp. Application of the signal precedes application of the ignitor pulses to the lamp. Disablement of the circuit can render the ignitor inoperable.

    摘要: A system that includes a multihop broadcast network of nodes that have a minimum of hardware resources, such as memory and processing power. The network is configured by gathering information concerning which nodes can communicate with each other using flooding with hop counts and parent routing protocols. A partitioned spanning tree is created and node addresses are assigned so that the address of a child node includes as its most significant bits the address of its parent. This allows the address of the node to be used to determine if the node is to process or resend the packet so that the node can make complete packet routing decisions using only its own address.

    摘要: An electrical connector for use in completing at least one electrical circuit is provided which includes a first half-connector body having an inner and outer flange structure which upon insertion into a housing comprising an orifice is effective to substantially envelop edge portions of the orifice to provide a substantially continuous seal between at least side and bottom edge portions of the orifice and connector. The first half-connector body also includes at least one opening for making electrical connection between electrical power-providing components and electrical power-receiving components. In especially preferred embodiments, the inner and outer flange structure define a substantially continuous groove about the periphery of the side and bottom edge portions and the connector includes an upper wall portion having a groove for containing a complementary tongue portion.
