Abstract: A magnetometer (20) comprises a magnetic field pickup coil (22) and a magnetic field detector (26) that receives electrical signals from the pickup coil (22) and produces an electrical detector output (28) responsive thereto. The pickup coil (22) and detector (26), which are preferably made of high temperature superconductors, are enclosed in an insulated enclosure (32) having no vacuum insulation structure. Preferably, the enclosure is made of a foamed polymer material such as styrofoam. A coolant is provided to the interior of the enclosure, to cool the pickup coil and detector to a temperature below their superconducting transition temperature. A number of such modular magnetometers may be connected together to form an array.

Abstract: A biomagnetometer (10) includes a magnetic field sensor unit including a magnetic field pickup coil (12). A vessel (16) contains the sensor unit. The vessel (16) includes a flexible contact face (e.g., 240) with the magnetic field sensor unit mounted in the interior of the vessel (16) adjacent to the flexible contact face. Insulation at the flexible contact face (240) of the vessel (16) prevents excessive heat flow through the flexible contact face (240). Pickup units using this structure can be connected together into flexible or rigid arrays. In operation, the pickup coil is cooled to a temperature of less than its superconducting transition temperature. A detector (30) measures the magnitude of magnetic fields sensed by the sensor unit.

Abstract: An apparatus for making bioelectromagnetic measurements of the human body includes an apparatus for measuring the bioelectromagnetic reaction (18) of a living body to a tactile stimulation and a tactile stimulator (40) that controllably applies a tactile stimulation to the body without creating a magnetic or electrical field that is detected directly by the apparatus for measuring the bioelectromagnetic reaction. The tactile stimulator includes a pressure chamber (52) closed on one side by a movable body such as a piston (76) or flexible membrane (56), a conduit (60) that transmits pneumatic pressure to the pressure chamber, and apparatus for applying pneumatic pressure (62) to the conduit. The measuring apparatus, such as a biomagnetometer (18), may be located within a shielded room (28), and in this case the pressure chamber (52) and movable body (76,56) are preferably located within the shielded room (28), the apparatus for applying pneumatic pressure (62) is located outside the room, and the conduit (60) passes from the exterior to the interior of the room.
