摘要： A wearable electric field detector configured to be worn by a wearer in an environment includes inner and outer housings which are movable relative to each other between a closed position and an open position. When in the closed position, a body of the inner housing is concealed within the outer housing, and when in the open position, the body is partially visible to visually indicate that the detector is open. The detector includes field detection circuitry which is configured to detect voltage in an electric field in the environment around the wearer. The circuitry is in communication with at least one of a speaker and a light source which are configured to be activated by the field detection circuitry.

摘要： A prober for testing devices in a repeat structure on a substrate is provided with a probe holder plate, probe holders mounted on the plate, and a test probe associated with each holder. Each test probe is displaceable via a manipulator connected to a probe holder, and a substrate carrier fixedly supports the substrate. Testing of devices, which are situated in a repeat structure on a substrate, in sequence without a substrate movement and avoiding individual manipulation of the test probes in relation to the contact islands on the devices, is achieved in that the probe holders are fastened on a shared probe holder plate and the probe holder plate is moved in relation to the test substrate.

摘要： A Kelvin probe according to one or more embodiments includes first and second probe pins in parallel to each other with a space in between. Each of the first and second probe pins includes: an elastic portion configured to expand and contract along a first line; a first contact on a second line parallel to the first line; and a second contact on the first line. The first and second contacts are directly electrically connected to each other, and supported such that at least one of the first and second contacts is reciprocally movable through an elastic force of the elastic portion. Both of the first contacts of the first and second probe pins are positioned between the first line of the first probe pin and the first line of the second probe pin when viewed on a plane comprising the first and second lines.

摘要： An electric field sensor for underwater, including a sensing unit that senses a change in an electric field and transfers a sensing signal of the electric field to a signal line, a waterproof sealing unit that keeps a signal transferring portion of the sensing unit in a waterproof state, and a water-passing protection unit that shields and protects an exposed portion of the sensing unit. The sensing unit includes a nonconductive hollow pipe connected to the signal line, a sheet of carbon fiber that is wound around the outer surface of the hollow pipe and that senses an electric field, and a terminal ring that is electrically conductively installed at an end portion of the sheet of carbon fiber to provide a connection portion of the signal line and that is watertightly sealed by the waterproof sealing unit.

摘要： In an embodiment, a testing system includes a frame, a DUT (device under test) testing module. The frame has at least one aperture extending from a front side of the frame to a rear side of the frame. The DUT testing module is inserted into the at least one aperture. The DUT testing module is operable to receive and hold a DUT receptacle including an electrical interface, an air flow interface, and a DUT coupled to the electrical interface. The DUT receptacle is configured to enclose and hold inside the DUT. Further, the DUT testing module is operable to couple to and to use the electrical interface and the air flow interface to perform a test at a controlled temperature on the DUT that is inside of the DUT receptacle.
