Abstract:
According to the present invention, there is provided a micro-fluidic sensor system (6) including a micro-conduit (56) for carrying fluid therethrough having a flexible wall portion (18), at least one micro-fluidic actuator having a closed cavity, flexible mechanism defining a wall of the cavity (11) and flexible wall portion (18) of the micro-conduit for deflecting upon an application of pressure thereto, and expanding mechanism (14) disposed in the cavity for selectively expanding the cavity and thereby selectively flexing said expanding mechanism, and sensor mechanism in fluid communication with the micro-conduit for sensing the presence or absence of molecules. The present invention further provides for a micro-fluidic system for moving micro-fluid amounts including a micro-conduit and at least one micro-fluidic actuator in fluid communication with the micro-conduit.
Abstract:
A probe position sensing system for accurately determining a spatial location in a coordinate system of a distal end of a probe assembly. The probe assembly includes an articulated arm having a pair of sections interconnected by a flexible joint and at least one element. The element extends through the joint and is positioned to be subjected to a degree of flexure due to relative displacement of the sections. A flexure of the element induces a change in a physical property associated with the element. An instrument monitors the physical property and derives an angle between adjacent sections from variations of the physical property.
Abstract:
A micro-fluidic pump (22) has a pulsating micro chamber (46) which includes a walled chamber (50). The walled chamber further includes at least one pulsating portion (52) actuable to pulse and change an interior volume of the walled chamber. An actuating mechanism (10) peristaltically moves fluids through a micro conduit (56). The actuating mechanism includes a closed pocket (11) adjacent to the conduit. A flexible mechanism (18) defines a portion of a wall of the micro conduit (56). An expanding mechanism (14) which is understood to be a fluid is disposed within the pocket (11) for expanding a volume of the pocket and thereby flexing the flexible mechanism (18) into the micro conduit thereby changing the volume of the conduit (56).
Abstract:
An insulation displacement connector device includes a base body, with a cutting clamp mounted on the base body and a closing element which may be displaced relative to the base body. The base body including an operating volume into which an operating tool may be introduced. The operating tool may be pivoted in a pivoting direction within the operating volume. The closing element may thus be moved between an open and a closed position. The closing element defines the operating volume on one side viewed from the pivoting direction.
Abstract:
