  • Patent number: 6684717
    Abstract: A high-resolution pressure-sensing device is disclosed. The device includes an insulating flexible matrix having a plurality of filler particles. Application of a force to the matrix causes compression of the matrix. This results in the filler particles occupying a greater amount of space within the matrix relative to when no force is applied. A detector attached to the matrix detects or measures the volume of the filler particles relative to the volume of the matrix, and therefore determines the force applied to the matrix. Preferably, the resistivity of the matrix is inversely proportional to the volume percent of the filler particles, in which case the detector is a resistance-measuring circuit.

  • Patent number: 6684720
    Abstract: A fluid transfer device includes a cylinder and a displacement rod. The cylinder is fabricated rigid enough to minimize distortion of volume yet compliant enough to create a seal between itself and the surface of the displacement rod. The cylinder is constructed with a bore hole through its central portion running from end to end. The diameter of the bore hole is larger than the diameter of the displacement rod. The displacement rod is constructed of a rigid material. At least one end of the cylinder has a diameter reduced so the diameter of the bore hole and the diameter of the displacement rod are substantially the same to form a seal with each other. As the displacement rod is withdrawn from the bore hole, a sample is drawn into the bore hole. The volume of the sample drawn into the bore hole is a function of the volume of the displacement rod withdrawn from the bore hole. A cross hole, for venting undesired fluid such as gas bubbles or previous sample(s), is located on the displacement rod.

  • Patent number: 6684743
    Abstract: A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system consists of a drive shaft 330, a slip clutch 401, a clutch gear 116, a drive gear 110, and a staggered gear 112 which controls the paper cutter blade 106. During printing, clutch 401 allows the drive shaft 330 shaft to slip relative to the clutch gear 116. When printing stops, clutch 401 locks clutch gear 116 which is engaged with the first portion of staggered gear 112 and causes staggered gear 112 to rotate until the second portion of staggered gear 112 engages the drive gear 110. Staggered gear 112 is then driven by the drive gear 110. A cutter blade is controlled by staggered gear 112, with the blade cutting off the paper as the drive gear 110 is in reverse rotation.
