摘要： Apparatus and methods for measuring current flowing through a conductor include a device comprised of a magnetically conductive loop (110) having a plurality of strands and a magnetic field sensor. Each strand has a magnetically conductive material. The strands are configured to pass a magnetic field to a first magnetic field sensor that is positioned adjacent to an end of the first plurality of strands. The plurality of strands may be arranged in various patterns that allow the magnetically conductive loop to be more bendable or flexible than a current-clamp device.

摘要： A clamp-on multimeter (100) measures alternating current flow in an electrical conductor. The multimeter includes a display (130), a housing (120) 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 (142a) fixed to the housing and a second clamp portion (142b) pivotally coupled to the first clamp portion. The second sensor includes a Rogowski coil (200) 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.

摘要： The present application provides a battery tester capable of measuring resistance and voltage of a battery using the same input channel. When measuring the battery resistance, a testing signal circuit of the battery tester is electrically coupled to two electrodes of a subject battery to conduct a testing signal used in the battery resistance measurement. A response sensing circuit of the battery tester is also electrically coupled to the two electrodes of the subject battery to measure a response signal across the two electrodes of the subject battery. A resistance measuring module is electrically coupled to the response sensing circuit to measure the battery resistance based on the response signal detected by the response sensing circuit. The battery tester also comprises a circuit breaker, capable of disconnecting the subject battery from the testing signal circuit, and disconnecting the resistance measuring module from the response sensing circuit. Moreover, the battery tester can also provide automatic protection for the battery resistance measuring module.

摘要： A system and method of coordinating power states between two detachable units is disclosed. Only the primary unit has a user-controllable power control. The secondary unit is not directly user controllable. The power states of the two units are coordinated using an actuator mechanism when the units are attached. When the two units are detached, the state of the secondary unit is dependent upon the state of the primary unit and any subsequent commands transmitted by the primary unit to the secondary unit.

摘要： A method for detecting a target analyte having a first binding site and a second binding site. A substrate is provided having at least a first and a second patterned conductor, the first conductor being separated from the second conductor. The arrangement of the patterned conductors forms at least two substantially non-conducting gaps. The method may also include contacting to the substrate capture probes that bind specifically to the first binding site of the target analyte and providing electrically conductive nanoparticles having bound thereto binding sites that bind specifically to the second binding site of the target analyte. Then, contacting the substrate and the to electrically conductive nanoparticles with the target analyte under hybridizing conditions will bind the target analyte to the substrate and to the electrically conductive nanoparticles. The electrically conductive nanoparticles between the conductors can thus be electrically detected. Detection can be improved by silver deposition of the nanoparticles.

摘要： To create a multimeter (1) with an erroneous input prevention mechanism (50) with increased degree of design freedom by assigning more than one mode to an input terminal hole (41) located in the central section out of a plurality of input terminal holes (41, 42, 43) selected by a rotary switch (30) and by enabling placement of a common terminal hole (40) within the rotation range of a shutter board (51).
Structure
In the multimeter, when the rotary switch is rotated, the first and the second drive-side protrusions (711, 712) formed at locations on the selector (71) separated by predetermined angle push away the first or second slave-side protrusions (721, 722) on the slave wheel (72), causing the shutter board to rotate with the center at the negative common terminal hole. As a result, only the specific terminal hole out of the input terminal holes is made to be in the open state. When the first input terminal hole 41 is in the open state and the rotary switch is rotated to a different predetermined position, the shutter board does not rotate, leaving the first input terminal hole in the open state.
