An ophthalmic surgical probe having a modular drive assembly and a skin that is removable from the drive assembly. This design simplifies probe manufacturing and provides greater manufacturing flexibility.

Aspects of the invention relate to a modular turbine vane assembly. The vane assembly includes an airfoil portion, an outer shroud and an inner shroud. The airfoil portion can be made of at least two segments. Preferably, the components are connected together so as to permit assembly and disassembly of the vane. Thus, in the event of damage to the vane, repair involves the replacement of only the damaged subcomponents as opposed to the entire vane. The modular design facilitates the use of various materials in the vane, including materials that are dissimilar. Thus, suitable materials can be selected to optimize component life, cooling air usage, aerodynamic performance, and cost. Because the vane is an assemblage of smaller sub-components as opposed to one unitary structure, the individual components of the vane can be more easily manufactured and more intricate features can be included.

An Internet enabled method and system (1) for designing, and manufacturing laser scanners of modular design and construction (231) using globally based information networks (3), such as the Internet, supporting the World Wide Web (WWW).

The present invention relates to an improved autonomous node seismic recording device having an integrated modular design and one or more features that assist coupling of the unit to the sea floor in order to improve the vector fidelity of seismic signal measurement.

A cardiovascular imaging and functional analysis system and method is disclosed, wherein a dedicated fast, sensitive, compact and economical imaging gamma camera system that is especially suited for heart imaging and functional analysis is employed. The cardiovascular imaging and functional analysis system of the present invention can be used as a dedicated nuclear cardiology small field of view imaging camera. The disclosed cardiovascular imaging system and method has the advantages of being able to image physiology, while offering an inexpensive and portable hardware, unlike MRI, CT, and echocardiography systems.The cardiovascular imaging system of the invention employs a basic modular design suitable for cardiac imaging with one of several radionucleide tracers. The detector can be positioned in close proximity to the chest and heart from several different projections, making it possible rapidly to accumulate data for first-pass analysis, positron imaging, quantitative stress perfusion, and multi-gated equilibrium pooled blood (MUGA) tests..In a preferred embodiment, the Cardiovascular Non-Invasive Screening Probe system can perform a novel diagnostic screening test for potential victims of coronary artery disease. The system provides a rapid, inexpensive preliminary indication of coronary occlusive disease by measuring the activity of emitted particles from an injected bolus of radioactive tracer. Ratios of this activity with the time progression of the injected bolus of radioactive tracer are used to perform diagnosis of the coronary patency (artery disease).

A method of controlling the conditional execution of elements and subsystems in a block diagram is disclosed. Data structures known as Execution Contexts are created and associated with individual block diagram elements and subsystems. The Execution Contexts allow execution of the associated element or subsystem upon satisfaction of a specified pre-condition. The Execution Contexts may be inherited by other elements and subsystems in the block diagram and propagated programmatically throughout the block diagram. The use of the Execution Contexts allows for efficient code generation and block diagram execution, as well as supporting modular design concepts.

An electronic electric meter for use in a networked automatic meter reading environment. The electric meter retrofits into existing meter sockets and is available for new meter installations for both single phase and three phase electric power connections. The meter utilizes an all electronic design including a meter microcontroller, a measurement microcontroller, a communication microcontroller and spread spectrum processor, and a plurality of other communication interface modules for communicating commodity utilization and power quality data to a utility. The electric meter utilizes a modular design which allows the interface modules to be changed depending upon the desired communication network interface. The meter measures electricity usage and monitors power quality parameters for transmission to the utility over a two-way 900 MHz spread spectrum local area network (LAN) to a remotely located gateway node. The gateway node transmits this data to the utility over a commercially available fixed wide area network (WAN). The meter also provides direct communication to the utility over a commercially available network interface that plugs into the meter's backplane or bus system bypassing the local area network communication link and gateway node.

An electrical connection box for wall mounting provides a recessed external plug for receiving or transmitting power to electronic components. The connection box is configured to receive a variety of signal connection modules for interconnecting associated audio / visual electronics such as DVD players, displays and the like in adjacent apertures. The signal connection modules are inserted or extracted from the face of the connection box; replacing blanking plates, and is optionally recessed from the face of the box into the wall cut-out. The configuration and mating features of the box and modules also provides for a common and isolated ground reference for surge protection of the connected components.
