  • Patent number: 8330449
    Abstract: A clamp-on multimeter measures alternating current flow in an electrical conductor. The multimeter includes a display, a housing including the display, a first sensor, a second sensor, a processor and an integrator. The first sensor has a magnetizable material core and inductively senses the alternating current. The first sensor includes a first clamp portion fixed to the housing and a second clamp portion pivotally coupled to the first clamp portion. The second sensor includes a Rogowski coil that has a non-magnetic core and inductively senses the alternating current. The processor receives an input signal in a first voltage range and sends an output signal to the digital display. The integrator scales a signal from the second sensor in a second voltage range to the first voltage range. The housing includes the processor, the integrator, and a selector configured to select the input signal to the processor from one of the first sensor and the integrator.

  • Patent number: 8259099
    Abstract: A solution for supporting servicing an outsource operation(s) using a three-dimensional (3D) data center is provided. In particular, a solution is provided in which a 3D data center is created from aggregating information technology (IT) resource data received from a plurality of outsourced operation locations that may be geographically or task distributed amongst multiple IT service providers.

  • Publication number: 20080288220
    Abstract: The present invention creates and/or uses a 3D data center that mirrors physical operations that may not all be co-located in one physical space. The 3D data center can cluster geographically dispersed similar physical assets into one area of the 3D data center, e.g., all of a company's physical world wide mainframes on one virtual floor of the 3D data center. Human experts that reside anywhere geographically could enter the 3D data center, service, manage, monitor their physical machines and applications and/or train other individuals living in different geographical locations, or working for other companies.

  • Patent number: 5820251
    Abstract: A self-illuminated, decorative ornamental device intended for indoor or outdoor residential use is suitable for day and night viewing. The device includes a planer surface having a two-dimensional color graphic image, and a multiplicity of electric lamps which are arranged on the surface to define a pattern which corresponds to the color graphic image. The color graphic image may include reflective elements to reflect light from the electric lamps.

  • Patent number: 5775540
    Abstract: A wall mounted inner housing in which a pair squeeze rollers are mounted in fixed side wall bearings. The front roller shaft can be selectively engaged by the outer housing, a three sided closure that hinges on the roller's shaft, where it serves two functions. Following a succession of direct finger squeezing/ dispensing actions the squeeze rollers are rotated, pulling the tube upwards, thereby compressing the tube, scavenging, consolidating and reconstituting the finger indented tube. The closure is then disengaged from the roller shaft wherein it again functions as a closure. A wall mounted device includes a two part housing, a pair of squeeze rolls set in fixed side wall bearings of inner housing. The outer housing, a three sided enclosure hinges on shaft of front roller, to which it can be locked, so as to rotate the squeeze rolls. An inverted collapsible tube is supported by the squeeze rolls its contents being dispensed by direct finger squeezing the neck of the tube.

  • Patent number: 5432706
    Abstract: A min/max time stamp for a multimeter provides display of minimum and maximum measured values recorded since enabling a min/max function. The minimum and maximum values, as well as a present value, may be displayed, together with the relative or absolute time at which the measured minimum or maximum occurred. An alert signal is generated to indicate a new maximum or a new minimum measurement.

  • Patent number: 5227984
    Abstract: An instrument having a continuity test feature wherein a change in continuity state from open-to-short or short-to-open is captured and displayed. A comparator provides continuity state information for a circuit under test. A storage device receives the state information and provides logic indicative of the continuity state which is read by a controller that executes a continuity capture program initiated by keypad or function selector input. A first transition between different continuity states is captured during a present capture cycle and is displayed in a form indicative of the type of transition captured. Subsequent transitions during the present capture cycle are ignored.
