Method and apparatus for improved building automation

An improved building automation system is provided which is modular in design thus minimizing the amount of instruction necessary to affect control of a particular building system. A relatively small set of interprocess control commands define an interprocess control protocol which is utilized in relatively high level scripts and control applications. The improved building automation system operates to translate control instructions in one particular control protocol to control instructions in a second control protocol. A text parsing program routes interprocess communication commands between modular communication programs to affect control over the automated building systems. The text parsing program includes executable instructions which allow for conditional communication of interprocess control commands depending upon system events.

A surgical instrument includes a shaft having a proximal end and a distal end with an operating device disposed at the distal end. A cable assembly is carried by the shaft and extends proximally to a terminus. A handle assembly coupled to the cable assembly concludes a first handle and a second handle. The first handle includes portions configured to receive the terminus and the proximal end of the shaft while portions of the second handle are configured to receive the terminus of the cable assembly. The proximal end of the shaft and the terminus are simultaneously rotatable to cover the proximal end of the shaft to the portions of the first handle and to couple the terminus to the portions of the second handle. The handle assembly can be made sterilizable with a minimum of non-bearing surfaces, while the shaft assembly can be made disposable and interchangeable with various operating devices.

Method for driving an ultrasonic system to improve acquisition of blade resonance frequency at startup

The ability of an ultrasonic system to sweep and lock onto a resonance frequency of a blade subjected to a heavy load at startup is improved by applying a high drive voltage or a high drive current while systematically increasing the level of the applied signal. Increasing the drive signal to the hand piece results in an improved and more pronounced “impedance spectrum.” That is, under load, the increased drive signal causes the maximum phase margin to become higher and the minimum / maximum impedance magnitude to become more pronounced. Increasing the excitation drive signal to the hand piece / blade at startup significantly alleviates the limiting factors associated with ultrasonic generators, which results in an increase of the maximum load capability at startup.

Method and apparatus for improved building automation

The improved building automation system of the present invention is modular in the extreme. This diminishes the amount of custom programming required in order to affect control of a particular building. It allows for a relatively open architecture which can accommodate a variety of unique control applications which are scripted for a particular building. By modularizing many of the common processes utilized in the automation system, the custom programming required to control any particular building is minimized. This modularity in design allows for uniform and coordinated control over a plurality of automation subsystems which may be incompatible with one another at the device or machine level, but which can be controlled utilizing a relatively small and uniform set of "interprocess control commands" which define an interprocess control protocol which is utilized in relatively high level scripts and control applications which may be written for a particular building.

Implantable joint prosthesis

The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable. Desirably, the outer surfaces of the shells are adapted to allow for bony ingrowth, which further stabilizes the shells in place. The inner surfaces of the shells are relatively smooth, and adapted to slide easily across a portion of the outer surface of a central body disposed between the shells. The central body has a shape that cooperates with the shape of the inner surface of the shell so as to provide a range of motion similar to that provided by a healthy joint. A flexible sheath extends between edges of the opposing shells. The inner surface of this sheath, together with the inner surfaces of the rigid shells, defines a cavity encasing the central body. At least a portion of this cavity is filled with a fluid lubricant, further decreasing the frictional force between inner surfaces of the shell and the surface of the central body.

Symmetrically and asymmetrically stacked transistor group RF switch

A silicon-on-insulator (SOI) RF switch adapted for improved power handling capability using a reduced number of transistors is described. In one embodiment, an RF switch includes pairs of switching and shunting stacked transistor groupings to selectively couple RF signals between a plurality of input / output nodes and a common RF node. The switching and shunting stacked transistor groupings comprise one or more MOSFET transistors connected together in a “stacked” or serial configuration. In one embodiment, the transistor groupings are “symmetrically” stacked in the RF switch (i.e., the transistor groupings all comprise an identical number of transistors). In another embodiment, the transistor groupings are “asymmetrically” stacked in the RF switch (i.e., at least one transistor grouping comprises a number of transistors that is unequal to the number of transistors comprising at least one other transistor grouping). The stacked configuration of the transistor groupings enable the RF switch to withstand RF signals of varying and increased power levels. The asymmetrically stacked transistor grouping RF switch facilitates area-efficient implementation of the RF switch in an integrated circuit. Maximum input and output signal power levels can be withstood using a reduced number of stacked transistors.

Light from the first light source is guided to the first light guide element, and the guided light undergoes reflective diffusion at the groove (a character section). As a consequence, a desired character, or the like, is luminously displayed. In the meantime, light generated by the light emission unit exits through the first light guide element, whereupon an area (a background area) other than the groove (the character section) is illuminated in color that differs from the color of light from the first light source.
