Abstract: The present invention relates generally to functional pathway configurations at the interfaces between integrated circuits (ICs) and the circuit assemblies with which the ICs communicate. More particularly, the present invention relates generally to the functional pathway configuration at the interface between a semiconductor device (e.g., computer chips like microcontrollers, microprocessors, application specific integrated circuits (ASIC), programmable gate arrays (PGA) and other devices and/or combinations thereof) and the circuitry of a system including the chip. Even more particularly, the present invention relates to a 14-pin microcontroller functional pathway configuration for the interface between the microcontroller and a system in which the microcontroller is embedded to support infrared communications.

Abstract: A valve and stem sealing assembly capable of preventing leakage under demanding environmental and operating conditions. The valve comprises a body and bonnet secured together to house a flow-element, stem, and stem sealing assembly. The body may contain a body joint encapsulated within its liner. The flow-element is positioned between a first port and second port on the valve. The body and bonnet may be configured to eliminate rotational forces from being translated to the bonnet. The stem sealing assembly comprises a primary seal, primary shaft insert, spacer, and force transmitting member. The stem sealing assembly may also comprise a secondary seal and secondary shaft insert. The stem seal assembly is substantially adjacent to the stem, and configured to fit within an annular space or cavity between the stem and the first body half, second body half, and bonnet. The valve may also include a leak detection port.
