The fault detection circuitry detects whether a fault is present in the battery pack. The sensors include a current sensor that senses a battery current of the battery pack. The fault detection circuitry includes a detection circuit that monitors a rate of change of a voltage at a terminal of the battery pack, and detects whether a fault is present in the current sensor based on a result of a comparison between the rate of change and a threshold and based on the detection result.Type: ApplicationFiled: August 8, 2018Publication date: February 21, 2019Inventor: Guoxing LI

Publication number: 20190056458Abstract: A test system is characterized by including: a holding unit that holds a light-receiving unit receiving light emitted from a test object; and an optical path forming unit that is formed with an optical transmission path as a path of the light received by the light-receiving unit, in which the optical transmission path is formed of a different member from the light-receiving unit. Since the test system has such a configuration, replacement of the light-receiving unit that receives the light emitted from the test object can be facilitated.Type: ApplicationFiled: August 3, 2018Publication date: February 21, 2019Applicant: Kabushiki Kaisha Nihon MicronicsInventor: Osamu ARAI

Publication number: 20190056459Abstract: A magnetic sensor includes a magnetic field conversion unit, a magnetic field detection unit, and a magnetic film. The magnetic field conversion unit includes a yoke that receives an input magnetic field and generates an output magnetic field. The input magnetic field contains an input magnetic field component in a direction parallel to Z direction. The output magnetic field contains an output magnetic field component in a direction parallel to X direction. The magnetic field detection unit includes a magnetic detection element that receives the output magnetic field and generates a detection value corresponding to the output magnetic field component. The magnetic film absorbs part of magnetic flux resulting from a noise magnetic field, which is a magnetic field in a direction to which the magnetic detection element has sensitivity and which is other than the output magnetic field component.Type: ApplicationFiled: July 6, 2018Publication date: February 21, 2019Applicant: TDK CORPORATIONInventors: Keisuke UCHIDA, Kenzo MAKINO

Publication number: 20190056460Abstract: An object of the present invention is to provide a magnetic sensor having enhanced magnetic detection sensitivity by bending magnetic flux more largely. A magnetic sensor includes magnetic detection elements MR1 and MR2 positioned on a plane P separating a first space S1 and a second space S2, a first magnetic member 31 disposed in the first space S1 so as to be between the magnetic detection elements MR1 and MR2 when viewed in the z-direction, and a second magnetic member 32 disposed in the second space S2. The magnetic detection element MR1 is positioned between the first magnetic member 31 and a first part 32a of the second magnetic member 32 when viewed in the z-direction. The magnetic detection element MR2 is positioned between the first magnetic member 31 and a second part 32b of the second magnetic member 32 when viewed in the z-direction.Type: ApplicationFiled: October 20, 2016Publication date: February 21, 2019Applicant: TDK CorporationInventor: Kei TANABE

Publication number: 20190056463Abstract: A significant enhancement of detection capabilities of the room temperature MPQ is seen using optical lithography-defined, ferromagnetic iron-nickel alloy microdisks. Irreversible transitions between strongly non-collinear (vortex) and a collinear single domain states, driven by an ac magnetic field, translate into a nonlinear magnetic response that enables ultrasensitive detection of material at relatively small magnetic fields.Type: ApplicationFiled: August 15, 2017Publication date: February 21, 2019Inventors: Valentine NOVOSAD, Elena A.

Publication number: 20190056465Abstract: The present disclosure relates to a method for a magnetic resonance system to protect a patient from being damaged by irradiated radio frequency power. In the method, amount information about maximum energy is determined as a function of a damage model for a patient to be examined with the magnetic resonance system. The maximum energy indicates the maximum radio frequency energy that may be radiated into the patient during the examination of the patient. Furthermore, an amount of energy emitted by a radio frequency amplifier of the magnetic resonance system during the examination of the patient in the magnetic resonance system is determined, and the radio frequency amplifier is adjusted as a function of a comparison of the amount information with the amount of energy emitted by the radio frequency amplifier.Type: ApplicationFiled: August 14, 2018Publication date: February 21, 2019Inventor: Volker Schnetter
