摘要： Methods, apparatuses, and systems for creating a proxy magnetic reference signal by frequency modulating a desired magnetic field proxy modulation onto an RF wave. A RF pulse sequence for an RF excitation source to apply a RF field to the magneto-optical defect center material can be based on a magnetic field proxy modulation and a base RF wave. The magnetic field proxy modulation can be indicative of a proxy magnetic field. A magnetic field measurement from a magneto-optical defect center material can be detected using the optical sensor and can include a proxy magnetic field based on the magnetic field proxy modulation.

摘要： 와전류 센서 장치는 코일부와 케이싱을 포함한다. 코일부는, 제1 자기장을 발생시키기 위한 여자 코일과, 제1 자기장에 의해 타겟 구조물에 유도된 와전류가 발생시키는 제2 자기장과 상기 제1 자기장의 합성 자기장에 상응하는 전기신호를 검출하는 센싱 코일을 포함한다. 케이싱은 상기 코일부를 내부에 수용하면서 둘러싸서 외부와 차단한다. 케이싱의 내부에 수납 고정되어 케이싱과 코일부를 타겟 구조물에 자력으로 고정시키기 위한 자력부를 더 포함할 수 있다. 긴장력에 기초하여 변동하는 응력을 제공하는 텐던의 긴장력을 텐던과 앵커헤드 사이에 압입되어 텐던의 응력에 따라 자기투자율이 변하는 적어도 하나의 쐐기의 표면에 와전류 센서가 설치된다. 긴장력 모니터링부는 와전류 센서에 여자 신호를 제공하는 한편, 와전류 센서가 검출한 전기신호를 이용하여 텐던의 긴장력에 관한 정보를 산출한다. 산출된 긴장력이 허용 임계값 이하로 떨어지면 위험 경보를 자동으로 발한다. 검사차량에서 자기유도방식으로 긴장력 모니터링부로 구동 전력을 제공하고 그 긴장력 모니터링부로부터 와전류 센서가 계측한 텐던 긴장력 정보를 수집할 수 있다.

摘要： In situ measuring devices, methods of making the same, and methods of using the same are provided herein. The in situ measuring devices can include a capillary tube having a reference material sealed inside the capillary tube, where the capillary tube is positioned inside of a solid state or MAS NMR rotor. A target sample can also be positioned in the interior of the solid state or MAS NMR rotor but is sequestered from the reference material by a capillary tube wall. The in situ measuring devices can be used in solid state MAS NMR spectroscopy to quantify one or more parameters of a target sample, such as the quantity of a sample, chemical identity of a sample, or temperature of a sample.

摘要： A method of calibrating an evaluation arrangement for non- destructive evaluation of test objects on the basis of magnetic Barkhausen noise. The evaluation arrangement comprises a magnetization coil, a sensor for sensing magnetic Barkhausen noise, and an apparatus for evaluating the test object based on signals from the sensor. The method comprises creating a varying magnetic field of an expected magnitude, measuring the magnitude of the created varying magnetic field and determining a deviation from the expected magnitude, and adjusting the evaluation arrangement to compensate for said deviation. The evaluation arrangement is used in one of the steps of creating and measuring the varying magnetic field.

摘要： A magnetic particle imaging apparatus includes magnets [106,107] that produce a gradient magnetic field having a field free region (FFR), excitation field electromagnets [102,114] that produce a radiofrequency magnetic field within the field free region, high-Q receiving coils [112] that detect a response of magnetic particles in the field free region to the excitation field. Field translation electromagnets create a homogeneous magnetic field displacing the field-free region through the field of view (FOV) allowing the imaging region to be scanned to optimize scan time, scanning power, amplifier heating, SAR, dB/dt, and/or slew rate. Efficient multi-resolution scanning techniques are also provided. Intermodulated low and radio-frequency excitation signals are processed to produce an image of a distribution of the magnetic nanoparticles within the imaging region. A single composite image is computed using deconvolution of multiple signals at different harmonics.

摘要： In one aspect, a mobile robot includes a chassis, a shell moveably mounted on the chassis by a shell suspension system, and a sensor assembly configured to sense a distance and a direction of shell movement relative to the chassis. The sensor assembly includes a magnet disposed on an underside of the shell. The sensor assembly further includes three or more Hall effect sensors disposed on the chassis in a triangular pattern at fixed distances such that the three or more Hall effect sensors are positioned beneath the magnet when no force is applied to the shell, wherein relative motion between the magnet and the Hall effect sensors causes the sensors to produce differing output signals. The mobile robot also includes a controller configured to receive output signals from the Hall effect sensors and to determine a distance and a direction of movement of the shell relative to the chassis.
