摘要： An integrated circuit package and method of fabrication are described. The integrated circuit package includes a lead frame having a first surface and a second opposing surface and a semiconductor die having a first, active surface in which circuitry is disposed and a second opposing surface attached to the first surface of the lead frame. A magnet attached to the second surface of the lead frame has a non-contiguous central region and at least one channel extending laterally from the central region. An overmold material forms an enclosure surrounding the magnet, semiconductor die, and a portion of the lead frame.

摘要： A system and method of effectively measuring a change in a gradient of a magnetic field. The systems include a first magnet and a second magnet mechanically coupled together and aligned along a polarization axis. The first magnet and the second magnet are positioned such that a pair of like magnetic poles of the first magnet and the second magnet face in opposite directions. Further, the first magnet and the second magnet are configured to move along the polarization axis in response to a magnetic field. A sensing system is configured to measure a change in a gradient of the magnetic field based on the movement of the first magnet and second magnet along the polarization axis in response to the magnetic field.

摘要： In a general aspect, a vapor cell includes a body defined by a stack of layers that includes electrically conductive layers and electrically insulating layers. The stack of layers are bonded to each other and have first and second end layers at respective opposite ends of the body. The stack of layers also has intermediate layers between the first and second end layers that define an internal cavity of the body. The internal cavity extends through the body between the first and second end layers and includes a vapor or a source of the vapor disposed therein. Adjacent electrically conductive layers are separated by at least one electrically insulating layer. Moreover, each electrically conductive layer defines an electrode of the vapor cell and includes a contact surface on an exterior side of the body. The contact surface defines an electrical contact of the electrode.

摘要： In a general aspect, a method includes interacting a beam of light with a vapor in a vapor cell. The vapor cell includes a body defined by a stack of layers that includes electrically conductive layers and electrically insulating layers. The stack of layers are bonded to each other and have first and second end layers at respective opposite ends of the body. The stack of layers also has intermediate layers between the first and second end layers that define an internal cavity of the body. A vapor is disposed in the internal cavity. The method includes applying respective voltages to one or more electrodes to alter an electric field in the internal cavity. The method also includes measuring one or both of an ion signal based on charged particles in the vapor and an optical property of the beam of light after interacting with the vapor.

摘要： A scalar magnetometer includes a sensor element, a circuit carrier, a pump radiation source, a radiation receiver and evaluation means. The pump radiation source emits pump radiation. The sensor element preferably includes one or more NV centers in diamond as paramagnetic centers. This paramagnetic center emits fluorescence radiation when irradiated with pump radiation. The radiation receiver converts a intensity signal of the fluorescence radiation into a receiver output signal. The evaluation means detects and/or stores and/or transmits the value of the receiver output signal. The material of the circuit carrier is preferably transparent for the pump radiation in the radiation path between pump radiation source and sensor element and transparent for the fluorescence radiation in the radiation path between sensor element and radiation receiver. The components sensor element, pump radiation source, radiation receiver and evaluation means are preferably mechanically attached to the circuit carrier .

摘要： A microelectronic device has a Hall sensor that includes a Hall plate in a semiconductor material. The Hall sensor includes contact regions in the semiconductor material, contacting the Hall plate. The Hall sensor includes an isolation structure with a dielectric material contacting the semiconductor material, on at least two opposite sides of each of the contact regions. The isolation structure is laterally separated from the contact regions by gaps. The Hall sensor further includes a conductive spacer over the gaps, the conductive spacer being separated from the semiconductor material by an insulating layer.

摘要： A radiofrequency (RF) shielding conduits that can be embedded within a doorframe and/or a door of a magnetic resonance imaging (MRI) room are disclosed. The RF shielding conduits can form, upon closing of door onto the doorframe, an RF shielding channel to enclose and/or allow passage of tubing of medical equipment extending from an interior of the MRI room to an environment that is external to the MRI room, while providing a RF shielding of the MRI room.

摘要： An integrated magnetoresistive device includes a substrate of semiconductor material that is covered, on a first surface, by an insulating layer. A magnetoresistor of ferromagnetic material extends within the insulating layer and defines a sensitivity plane of the sensor. A concentrator of ferromagnetic material includes at least one arm that extends in a transversal direction to the sensitivity plane and is vertically offset from the magnetoresistor. The concentrator concentrates deflects magnetic flux lines perpendicular to the sensitivity plane so as to generate magnetic-field components directed in a parallel direction to the sensitivity plane.
