The base portion may also include electrical components suitable for displaying, wirelessly transmitting, and/or otherwise conveying the measured electrical parameters. In some embodiments, the distal end of the probe may be removably received by the base portion, such that the probe forms a loop encircling the conductor when measuring it. In other embodiments, the probe may resiliently clip on to the conductor. In another example, an electrical sensor includes an attachable tag that can be mounted to the conductor to be measured.

    Abstract: A probe sensor has a printed circuit comprising a coplanar transmission line, a ground plane, a plated-through contact via, and a part-circular ring of ground vias surrounding the contact via. The coplanar transmission line and ground plane are formed on a first layer of the printed circuit, and the contact via and part-circular ring of ground vias are plated with a conductive biocompatible material on a second layer of the printed circuit. A system uses a network analyzer with the probe to measure electrical properties of biological tissue. Also described is a method of using the system to determine qualities of stored blood.

  • Patent number: 8917084
    Abstract: The present invention is an efficient high voltage sensing mechanism that operates only when an individual needs to test the voltage across a wire. The present invention attaches around a tested wire using a jaw and a hook. The hook is tensioned using an expansion spring. The operator propels the hook outwards from the jaw, around the tested wire; thereafter, the expansion spring retracts to latch onto the tested wire against the jaw. An on-off switch is integrated into the mechanical hook device. As the hook is propelled outwards, the on-off switch moves into the “on” position, which powers the electrical processing and voltage analysis equipment. Once the hook is returned to the initial position, the on-off switch moves to the “off” position. This arrangement allows the present invention to remain unpowered for any instance a wire is not being tested. The present invention detects voltage through capacitive coupling.

  • Publication number: 20140320145
    Abstract: An oscilloscope system includes a current probe, a processing unit and a display unit. The current probe includes a high and low gain signal paths for receiving simultaneously a signal of interest from a device under test (DUT), and to output amplified small and large current portions of the signal of interest, respectively. The processing unit receives first and second digitized data corresponding to the amplified small and large current portions output by the high and low gain signal paths, respectively, and processes the first and second digitized data for display as zoomed-in and zoomed-out waveform data, respectively. The display unit displays simultaneously a zoomed-in waveform in a first display window, based on the zoomed-in waveform data, and a zoomed-out waveform in a second display window, based on the zoomed-out waveform data, using the same time scale. The small current portion is less than a predetermined threshold.
