摘要： A level including level vial(s) having enhanced visibility are provided. The level may include a level vial including a material that is attracted to the interface or border of a globule within the level vial which improves visibility of the interface. The level may include a solid level indicator having easy to see end surfaces that are generally vertically oriented when in the level position. The end surfaces of the solid level indicator may allow the user to more easily compare the position of the solid level indicator to indicating lines formed on the level vial. The level may include a level vial including a first liquid and an immiscible second liquid forming a globule with the first material. The globule formed from the second material may improve visibility compared to a typical air bubble.

摘要： A slope/level indicating apparatus for determining the degree of slope or grade being created by a machine, such as a grader. The apparatus comprises a slope indicator unit which transmits slope information through a cable to a digital display which can be viewed by an operator. The slope indicating unit comprises one or more tubular chambers, each of which has a substantially rectangular transverse cross-section, and each of which includes a disk that can move freely within the tubular chamber. The tubular chamber is machined or molded with the longitudinal axis curved in an arc of one or more predetermined radii so that the disk moves within the tubular chamber according to the earth's gravitational force vector. A plurality of photodetectors are situated preferably evenly spaced behind the tubular chamber and are preferably placed such that they detect transitions of slope of the tubular chamber based on the position of the disk within the tubular chamber. A light source located on the opposite side of the tubular chamber shines light onto and through each tubular chamber, the light being received by the respective photodetectors except the one being blocked by the disk. In this manner, the machine operator is kept apprised in real time of the level of slope being created and/or used by the machine.

摘要： A ferrofluid sensor assembly includes a closed housing containing a movable inductance core material that is isolated from the inner walls of the housing by an isolating material. The isolating material forms a layer between the inductance core material and the walls of the housing to prevent their contact. A detector also is included for detecting the position of the inductance core material within the housing.

摘要： A ferrofluid sensor assembly includes a permanent magnet which is supported in a hermetically-sealed housing by ferrofluid rings at each end of the magnet. However, the housing is large enough that the ferrofluid rings do not seal the end of the magnet against the walls of the housing. The housing is filled with a non-magnetic liquid that is immiscible with the ferrofluid. The nonmagnetic liquid wets the walls of the housing such that the ferrofluid rides on the thin film of the nonmagnetic liquid. The non-magnetic fluid is selected to have low viscosity, so that the magnet has a fast response time.
