摘要： Disclosed herein is an RF ablation system including a plurality of electrodes, a ground pad, and a signal generator. The electrodes are positioned at respective tissue sites within a patient's body, and the ground pad is positioned on the patient's body. The signal generator is coupled to the ground pad and the electrodes via corresponding channels including a selected channel and unselected channels. The signal generator commutates switching circuits for the corresponding channels to close the selected channel and to open the unselected channels, and measures a first impedance over the selected channel. The signal generator commutates the switching circuits to close the selected channel and the unselected channels, and then measures a second impedance. The signal generator computes a difference between the first and second impedances, and determines the ground pad has at least a poor electrical connection to the patient's body when the difference exceeds a threshold.

摘要： This applications relates to methods and apparatus for monitoring a socket (101), to detect a connection status of a mating plug (102), e.g. for monitoring an audio jack socket for connection of an audio jack plug. A monitor (115, 305) is configured to monitor a voltage (VM) at a monitoring node (114), which is coupled to a jack detect contact (112) of the socket and a voltage pull-up element (113). The voltage (VM) at the monitoring node (114) is monitored against a threshold (Vthv) and a threshold module (302) is configured to vary the threshold depending on an indication of signal activity (SACT) of a signal path for a first socket contact (103) which will be electrically connected to the jack detect contact when a plug when inserted in the socket.

摘要： A test coverage rate improvement system for pins of tested circuit board and a method thereof are disclosed. In the system, partial pins of a circuit board connector in a tested circuit board are not electrically connected to the boundary scan chip, test pins of the test pin board are pressed with the partial pins by a fixture of a boundary scan interconnect testing workstation to electrically connect the test pins to the partial pins. A test access port controller receives a detection signal for detecting the partial pins, which are not electrically connected to the boundary scan chip, of the circuit board connector through the test pin board from the test adapter card, and determines whether conduction is formed based on the detection signal, thereby achieving the technical effect of improving a test coverage rate for the pins of the tested circuit board.

摘要： A testing device includes a measuring unit, a testing board supporting the measuring unit and connected to the measuring unit, and a connecting interface coupled to the testing board. The connecting interface includes connecting terminals protruding in a direction away from the testing board, and is connected to a device under test (DUT) via the connecting terminals. When the DUT is connected to the connecting interface, the measuring unit supplies a constant electric current via the testing board and the connecting interface to the DUT for a preset duration to result in a voltage, measures the voltage, and determines, based on a result of measurement of the voltage, an electrical connection status of the DUT.
