Abstract:
A probe station is equipped with an integrated guarding system which facilitates the use of the station for low-current measurements, as well as integrated Kelvin connections to eliminate voltage losses caused by line resistances. The station has a chuck assembly (20) which consists of at least three chuck assembly elements (80, 81, 83). A first element (80) supports the test device, while an underlying second element (81) acts as a guard to reduce leakage currents. These elements are electrically insulated from each other and from their underlying supporting structure, which is the third element (83). Ready-to-use, selectively detachable electrical connector assemblies (108, 110) provide for signal and guard connections to the first and second chuck assembly elements (80, 81) respectively, as well as providing Kelvin connections thereto. The capacitance between the respective chuck assembly elements (80, 81, 83) is extremely low due to the provision of air space as the primary electrical insulator. Unique electrical connectors (128, 130) for individually-positionable probes (30) provide both guarding and Kelvin connection capability together with separate EMI shielding movable in unison with each probe individually.

Abstract:
A system and method for maintaining an air inflation mattress configuration sufficient for patient support and comfort. Infrared illumination levels are measured within individual or groups of inflated mattress chambers. A staggered approach to illumination monitoring of chambers or sections to eliminate crosstalk between the infrared sensors is carried out. Distributed microprocessor controllers established in a network configuration utilizing controller network protocols reduces the wiring and connections necessary for the assembled system. Various mattress cushion construction techniques, such as sewing and or RF welding methods, are used for the creation of individual chambers utilizing specific types of IR translucent, transparent or reflective materials. The construction of the cushions and bladders in the system includes the use of various types of fabrics with low to high air loss qualities as required. The overall mattress assembly, including the control systems and the methodologies associated with such control systems, provide a unique approach to the maintenance of a consistently comfortable patient support surface. The use of a handheld unit for both programming the system and downloading information about the operation of the system is also anticipated. The specific cushion construction designs associated with the head, body, and foot cushion components of the mattress are tailored to operate specifically with the control capabilities (sensors and air flow regulators) of the invention.
