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.

Abstract: A biomagnetometer (20) includes a dewar vessel (34) having a helmet-shaped recess (54) at the lower end of its body (36). The recess (54) is angled at about 45 degrees to the dewar body axis of the dewar vessel. Biomagnetic sensors (26) are positioned within the interior of the dewar vessel body (36) around the periphery of the recess (54). The angled recess (54) permits the biomagnetometer (20) to be used with subjects (24) whose heads (22) are inclined from 0 to 90 degrees to the horizontal by pivoting the dewar vessel (34) over an angle of from -45 degrees to +45 degrees to the vertical, without spilling the cryogenic fluid within the dewar (34) or causing excessive evaporation of the cryogenic fluid.

Abstract: A biomagnetometer comprises an array of biomagnetic sensors, the array comprising a first plurality of magnetic field pickup coils, and a second plurality of detectors, each of which receives a pickup coil output from a pickup coil. There is a third plurality of signal processors, each of which receives an output from a detector, the third plurality of signal processors being fewer in number than the first plurality of pickup coils. The biomagnetometer further includes a selector that selects a subset of pickup coils, equal in number to the third plurality of signal processors, from the first plurality of pickup coils for signal processing by the signal processors. This biomagnetometer permits the placement of a very large array of relatively inexpensive pickup coils adjacent to a subject, and then processing information from subsets of that large array selected to optimize the gathering of data, while maintaining the cost of the signal processing electronics at a more economical level.
