  • Patent number: 10605844
    Abstract: An isolation test system for a vehicle includes a communication interface, a current sensor, a plurality of impedances and a controller. The controller is programmed to electrically connect a selected one of the impedances between a traction battery of the vehicle and a low voltage subsystem of the vehicle. The connection creates a leakage path between the traction battery and the subsystem. The controller is further programmed to output a diagnostic status based on a current associated with the leakage path and a signal received via a communication interface indicative of an isolation fault between the battery and subsystem.

  • Patent number: 10585203
    Abstract: A radio frequency (RF) imaging device comprises a position sensor, an optical sensor, a processor, and an output. The position sensor determines a position of the RF imaging device relative to a surface. The optical sensor captures optical image data representing an optical image of an area of the surface. The optical image data is associated with position data representing a position relative to the surface derived from the determined position of the RF imaging device. The derived position data corresponds to the area of the surface imaged by the optical sensor. The processor produces a composite image in which one or more portions of the optical image data are simultaneously viewable with RF image data representing an RF image of a space behind the surface at the same position as the optical image data. The output displays the composite image. The output may be a projector.

  • Patent number: 10578649
    Abstract: Vertical probe heads having a space transformer laterally tiled into several sections are provided. This change relative to conventional approaches improves manufacturing yield. These probe heads can include metal ground planes, and in embodiments where the ground planes are provided as separate metal plates parallel to the guide plates, the metal plates can also be laterally tiled into several sections. Such tiling of metal plates improves manufacturing yield and alleviates thermal mismatch issues. Probes are not mechanically connected to the space transformer, which facilitates replacement of individual probes of an array.

  • Patent number: 10571591
    Abstract: A radio frequency (RF) imaging device comprises an optical position sensor, an RF sensor assembly, a processor, and a memory. The optical position sensor captures an optical image of a field of view and outputs data representing the optical image. The RF sensor assembly is disposed at a first position and receives an RF signal for capturing an RF image of a portion of a space disposed behind a surface at the first position and outputs data representing the RF signal. The processor receives the data representing the optical image and the RF signal, and determines that an optical signature of a reference marker is present in the optical image. If the optical signature is present in the optical image, the processor defines the first position of the RF assembly as a reference position. The memory stores the data representing the RF signal in association with the reference position.

  • Patent number: 10557882
    Abstract: The present invention relates to an apparatus and a method for sensing an event occurring from a target device in a smart plug installed on a supply route of power applied to the target device. To this end, a power measurement unit which comprises the smart plug measures power supplied to the target device, and an event determination unit predicts an event occurring from the target device on the basis of a power signal characteristic of the supplied power measured by the power measurement unit. The power signal characteristic indicates a variation characteristic of the supplied power caused by the occurrence of the event on the basis of supplied power before the event occurs from the target device.

  • Patent number: 10539706
    Abstract: A ranging signal and a reference signal are generated. The reference signal has a lower frequency than the ranging signal. The reference signal is transmitted through a geological formation to be received by a ranging tool in a ranging well while the ranging signal is launched down a target well. The reference signal is reconstructed in the ranging well and a signal that is a combination of the ranging signal launched from the target well and noise are received in the ranging well. The received signal may be in the form of magnetic or electric field values or changes in these fields. The reconstructed reference signal, in combination with the received signal, is used to produce a filtered ranging signal. A relative location of the target well can then be determined in relation to the ranging well based on the filtered ranging signal. The location information can be used to direct drilling operations.

  • Patent number: 10534048
    Abstract: A Q value of the RF irradiation coil is easily obtained in a state in which an object is disposed in an MRI apparatus, and an SAR is predicted with high accuracy. For this, an irradiation coil 14a irradiates an object 1 with a high frequency magnetic field pulse in a state in which the object 1 is disposed in an imaging space, and a transmitted voltage and a reflected voltage of the irradiation coil 14a are detected. A Q value of the irradiation coil in a state of the object 1 being disposed is obtained on the basis of the transmitted voltage and the reflected voltage. A specific absorption rate (SAR) in a case of executing an imaging pulse sequence on the object is predicted by using the Q value.
