  • Patent number: 7525328
    Abstract: A lossy dielectric device dissipates, absorbs, and/or dampens electric fields. The lossy dielectric device may be used with any transmission path, such as a transmission line or resistor in a probe head. The lossy dielectric device preferably includes a lossy dielectric material contained within a container. The container is positionable and securable substantially adjacent the transmission path to improve the curve of a frequency response. Preferably, the container is insulative, puncture resistant, and thin. In some preferred embodiments, a temporary or permanent connection mechanism is also included.

  • Patent number: 7432698
    Abstract: A modular active test probe and removable tip module therefor. Within the scope of the invention, there is a probe tip module comprising a first probe tip adapted for probing a circuit under test to receive a signal therefrom. The probe tip module includes an amplifier having a first input solidly connected to the probe tip, an output connected to an output connector, and a housing for supporting the probe tip, the amplifier, and the output connector. A probe body is cooperatively adapted with the housing for repeatably removably receiving at least the output connector.

  • Patent number: 7378832
    Abstract: Apparatus and associated systems and methods may relate to a wide bandwidth cable assembly that may include an active amplification stage to receive high frequency signals (e.g., 1 GHz or above) through a transmission line extending distally to a passive, high density signal probe stage. In an illustrative example, the probe stage may receive multiple analog or digital signals from a device under test (DUT). In some embodiments, the probe stage may include probe pins with integrated series resistance to control signal loading, and an equalizer to shape the signal path's frequency response. The amplification stage may provide a virtual ground reference for a termination impedance that may match the transmission line's impedance and may connect in series with a feedback impedance. In one example, a minimally invasive probe head may facilitate measurement of multiple channels of a high speed data bus with minimal signal distortion and/or attenuation.

  • Patent number: 7321234
    Abstract: A test probe tip constructed substantially from resistive material. The resistive material is made of resistive conducting material substantially enclosed in and dispersed throughout encapsulating material. The test probe tip has a probing end for probing electronic circuitry and a connection end for interfacing with a probing head. The resistive conducting material forms at least one path through the encapsulating material from the probing end to the connection end. The resistive conducting material may be a plurality of longitudinally-extending resistive/conductive members or a plurality of particulate resistive/conductive members.

  • Patent number: 7317312
    Abstract: A guide for tip to transmission path contact includes a guide insulator having at least one passageway defined therein. Each passageway has a tip passageway end and a transmission path passageway end. The tip passageway end is suitable for at least partially accommodating the tip of a probing head. The transmission path passageway end is suitable for at least partially accommodating a transmission path of a circuit board component. The tip contacts a transmission path through a passageway when the transmission path is positioned in the transmission path passageway end and the tip is positioned within the tip passageway end.

  • Publication number: 20070219819
    Abstract: A method of detecting title fraud utilizes an electronic database in which is stored information relating to one or more title transactions. Such information includes common addresses of real estate properties, and at least one of a type of title transaction involved, and identifying indicia of parties to the title transactions. The method initiates a title order to a settlement agent for a new title transaction involving settlement services relating to a particular real estate property, and then searches the database for at least one other title transaction involving the same particular property, parties, or other indicia in common with said title order, and for any copendency during a period between the title order initiation and subsequent registration and indexing of the title transaction after the title transaction is completed.

  • Patent number: 7262614
    Abstract: A substantially planar (in an x-y plane) probing tip includes a probing tip body and two test point connector projections. The first test point connector projection is movably attached to the body to allow motion therebetween. The second test point connector projection is also attached to the body. The motion actuator actuates motion that the motion translator, in turn, converts to move at least one of the test point connector projection connection ends in a third dimension out of the x-y plane. The probing tip has an open position in which the relative distance between the test point connector projections is relatively large. The probing tip also has a closed position in which the relative distance between the test point connector projections is relatively small. In one alternative preferred embodiment, the second test point connector projection body end is also movably attached to the body to allow motion therebetween.
