A traffic light system (10) with an impedance matching circuit (14) for electrically coupling an optical assembly (12) to a switched AC power supply (26) is described. The impedance matching circuit (14) has a matching transformer (20), a first resistor chain (22) and a second resistor chain (24). Each resistor chain (22,24) has an input and an output. Each of the inputs is common with a respective electrical node of the matching transformer (20). Each of the outputs is common with a respective ...

Computer instructions that operate to determine if one or more geometry pieces of a mechanical design are within a view boundary and automatically generate and order one or more identifiers corresponding to the geometry pieces within the view boundary, when executed, is disclosed. In one embodiment, the computer instructions are part of a mechanical design software application. In one embodiment, the mechanical design software application including the computer instructions are embodied in a dis...

A display device having an integral docking station to facilitate the display device to be used in conjunction with a palm sized computing device for applications executing on the palm sized computing device is disclosed. The display device includes a flat panel display, a display controller, a microcontroller, a docking station including a communication interface, and a chassis integrally housing the earlier enumerated elements. Together, the enumerated elements facilitate removable coupling of...

An emulation system equipped to emulate multiple circuit designs concurrently is disclosed. The emulation system includes an emulator having reconfigurable emulation resources for emulating circuit designs, and a host system programmed with programming instructions that operate to generate coordinated configuration information for a number of circuit designs to enable the reconfigurable emulation resources to be configured in a coordinated manner to allow the circuit designs to be emulated concu...

A "state" icon having a plurality of manifestations corresponding to a plurality of states associated with saving a copy of a current information page being browsed is automatically displayed for a user. The "state" icon denotes to the user whether the information page or other variants have been previously saved. A "single click" icon is employed to facilitate saving a copy of the current information page being browsed for a user. The saving is accomplished without requiring further interaction...

An optical networking module is formed with an integrated module including optical, optical-electrical and protocol processing components, and complementary software. In one embodiment, the integral protocol processing component is a single ASIC and supports multiple protocols. The module is further equipped with support control electronics in support of control functions to manage the optical, optical-electrical as well as the multi-protocol processing component. The integrated module together ...

An apparatus comprising a storage medium and a communicatively coupled processor are presented. The storage medium has stored therein a plurality of executable instructions which, when executed, implement an information server which, upon receiving a request including a resource identifier for an information page that may or may not exist, constructs and issues commands to retrieve the requested information and dynamically generates instructions to create the requested information page for provi...

An improved infrared (IR) imaging arrangement for a turbine component inspection system includes a platform having a turbine component base feature to receive a turbine component for inspection. Disposed on the platform are a number of mirrors around the turbine component feature. The number of mirrors simultaneously reflects a number of sides/edges for detection by an IR imager. As a result, the IR imager simultaneously view more than one sides/edges of a turbine component.

A programming environment can be modified to provide automatic support for reverting program memory states. Such memory reversions are used to provide automatic support for state-reversion, undo, redo, and abort operations for application programs written with the programming environment. Memory allocation code (e.g., functions, procedures, etc.) are modified to mark allocated memory as protected, and an exception handler is assigned to such memory. Attempts to access the memory cause an excepti...

An overhead processor processes overhead bytes in a stream of Synchronous Optical Network (SONET) frames in multiple levels. In one embodiment, the overhead processor includes three stages. A first stage provides access for external processing of a first set of overhead bytes in the stream of SONET frames. A second stage is programmable to process a second set of overhead bytes in the stream of SONET frames. A third stage processes a third set of overhead bytes in each frame in the stream of SON...
