摘要： An arc detection system includes an obtainer and a determiner. The obtainer obtains a measurement result for current flowing in a power supply line to which power is supplied from a DC power source. The determiner determines, based on a component of a specific frequency band in the measurement result for the current obtained by the obtainer, whether an arc fault has occurred. The determiner determines that the arc fault has occurred when a specific time for which the component of the specific frequency band is at least a threshold is longer than an occurrence time in which an arc can occur when a device is attached to or detached from the power supply line.

摘要： A contactor includes: at least one moveable contact mounted on a contact carrier; at least one stationary contact mounted on a housing; an electromagnet arranged to cause the contact carrier to move relative to the housing between a first position and a second position, and thus to cause the at least one moveable contact to travel from a contacts open position to a contacts closed position with respect to the at least one stationary contact; a sensor coupled to one of the contact carrier and the housing and arranged to detect an intermediate position, in between the first position and the second position, at which the housing and the contact carrier are located at a given moment in time as the contact carrier moves relative to the housing between the first position and the second position; and a controller connected to receive the signals from the sensor.

摘要： A system includes a dry contact with a first pair of switchable electrodes, a wet contact with a second pair of switchable electrodes, an arc suppressor operatively, and a controller circuit operatively coupled to the arc suppressor and the first and second pairs of switchable electrodes. The controller circuit is configured to detect a failure of the wet contact and determine a stick duration associated with the first pair of switchable electrodes. The controller circuit generates a health assessment for the first pair of switchable electrodes based on a comparison of the determined stick duration with an average stick duration associated with a window of observation.

摘要： Disclosed are systems and methods of operation for capacitive radio frequency micro-electromechanical switches, such as CMUT cells for use in an ultrasound system. An RFMEMS may include substrate, a first electrode connected to the substrate, a membrane and a second electrode connected to the membrane. In some examples, there is a dielectric stack between the first electrode and the second electrode and flexible membrane. The dielectric stack design minimizes drift in the membrane collapse voltage. In other examples, one of the electrodes is in the form of a ring, and a third electrode is provided to occupy the space in the center of the ring. Alternatively, the first and second electrodes are both in the form of a ring and there is a support between the electrodes inside the rings.

摘要： An in-plane sliding parallel capacitive radio frequency (RF) switch includes a substrate, first to third drive components, an insulating layer, and a sliding component. Where a drive voltage is applied between the first and second drive components, the sliding component slides to the top of the first and second drive components; in this case, relatively large capacitance is formed between the first and second drive components and the sliding component, a RF signal is almost completely reflected, and the transmission is cut off. Where the drive voltage is applied between the second and third drive components, the sliding component slides to the top of the second and third drive components; in this case, no facing area between a first drive electrode and the sliding component exists in a vertical direction, the capacitance is rather small, and the RF signal may be transmitted basically without loss.

摘要： According to one embodiment, a MEMS element includes a first member, and an element part. The element part includes a first fixed electrode fixed to the first member, a first movable electrode facing the first fixed electrode, a first conductive member electrically connected to the first movable electrode, and a second conductive member electrically connected to the first movable electrode. The first movable electrode is supported by the first and second conductive members to be separated from the first fixed electrode. The first conductive member has a meandering structure. The second conductive member includes a first conductive region and a second conductive region. The second conductive region is between the first movable electrode and the first conductive region.

摘要： The present disclosure provides scalable nanotube fabrics and methods for controlling or otherwise adjusting the nanotube length distribution of a nanotube application solution in order to realize scalable nanotube fabrics. In one aspect of the present disclosure, one or more filtering operations are used to remove relatively long nanotube elements from a nanotube solution until nanotube length distribution of the nanotube solution conforms to a preselected or desired nanotube length distribution profile. In another aspect of the present disclosure, a sono-chemical cutting process is used to break up relatively long nanotube elements within a nanotube application solution into relatively short nanotube elements to realize a pre-selected or desired nanotube length distribution profile.
