Abstract: A magnetotherapeutic device incorporates bio-ceramic fibers so as to provide simultaneous magnetotherapy and far infra-red wave therapy. Generally encased in clear plastic or the like, the magnetotherapeutic device of the present invention may take the form of a transparent disk having a plastic rim. A stainless cap may provide an attractive top surface into which a logo or symbol may be embossed. It also enhances the magnetic affects on the side opposite the stainless steel cap, the side that is applied to the body. A strong magnet such as one incorporating neodymium may underlie the stainless steel cap to provide magnetotherapy in the present invention. Bio-ceramic fibers emitting the far infra-red wavelengths of 8-14 microns underlie the strong neodymium magnet. A mat of woven bio-ceramic fibers or the like may provide such a structure.

Abstract: A device for applying a time-varying magnetic field to a human or animal body for therapeutic purposes comprising magnetic unit that is made to rotate about two separate axes at the same time housed within non-magnetic components, which insrotatably housed in a non-magnetic free moving member, which itself may rotating about an axis oblique to the axis of rotation of the magnet. The device may be held in the operator's hand or attached to his or her clothing, and is powered by a small electric motor that drives the gears necessary to produce the separate rotary movements. One axis of rotation is in the direction of a rod mounted to the magnet, and the other axis is along an imaginary line that runs through the center of the magnet body, roughly perpendicular to the rod. The two rotational movements of the magnet produce both a time-varying field of magnetic flux density and a time-varying field of angular flux displacement.

Abstract: Magnet spirals for therapeutic application with minimum one foil strip made of a rubber-type flexible, preferably skin compatible, plastic which is coiled up along its lengthwise dimension in form of a spiral, whereby the foil strip is magnetically polarized in an axial direction relative to its larger lateral face (i.e. in its lengthwise direction). The larger lateral faces of the foil strip are magnetically polarized in an axial direction of the foil—that is, in the lengthwise direction of the foil strip, preferably up to its total saturation. In the coiled condition of the foil, one side of the larger lateral area thus faces the other large lateral area. Starting at the center this configuration creates in a radial direction a sequence of varying magnetic polarizations within the cross section of the magnet spiral. The effect of this series arrangement of the magnetic polarizations causes the creation of a particularly strong magnetic field in the vicinity of the magnet spiral.

Abstract: An apparatus for and a method of measuring material thickness with magnetics. The thickness monitoring system includes a thickness monitor, a probe, and a target. In a preferred embodiment, the probe is positioned on one side of an article for which the thickness is to be determined. The target is positioned on the opposite side of the article from the probe. The probe includes an excitation coil, a field compensation coil, and a magnetic sensor. The method includes energizing the excitation coil to excite a response from the target, compensating for the effect of the excitation coil on the magnetic sensor, measuring the response of the target with the magnetic sensor, and determining the thickness of the article from the measured response. The preferred mode of energizing the excitation coil is with an AC waveform; however DC, multi-frequency AC, or a combination of AC and DC waveforms may be used.

Abstract: A probe instrument using room-temperature sensor(s) that can measure magnetic susceptibilities variations. The instrument includes room temperature magnetic sensors, and detects the sample, that is the tissue response to an applied field coil. The sensors that can be used include magnetoresistive, fluxgate and magnetoinductive sensors. The applied field coil dimensions are chosen so that the applied field is optimized for maximum response from the item of interest while minimizing the effects due to the overlying tissue and at the same time not unduly increasing the sensitivity of the instrument to adjacent organs. To minimize noise introduced in the sensor due to fluctuations in the applied field, the applied field is canceled at the position of the sensor. To overcome variations in the sensor output due to fluctuations in the applied field, change in the ambient temperature and mechanical relaxation of the instrument, the detector assembly is oscillated while the examined patient remains stationary.

Abstract: A method and system for canceling extraneous signals in a nuclear quadrupole resonance (NQR) system used for the detection of explosives and drugs. A specimen is irradiated with a specific sequence of electromagnetic pulses, referred to as a spin-locked inversion mid-echo (SLIME) pulse sequence with each pulse having a specified phase and duration. The pulses are separated by specified time intervals. The SLIME pulse sequence has a single excitation pulse. As a result of the characteristics of the SLIME pulse sequence, if the target substance to be detected is present in the specimen, sets of oppositely-phased NQR echo signals are generated from the target substance. NQR echo signals of one phase are subtracted from NQR echo signals having the opposite phase, rendering a cumulative echo signal, and simultaneously subtracting out the same-phase extraneous signal.

Abstract: A magnetic insole provides magnetotherapy for the soles of a wearer's feet. A laminated insole in the general shape of a foot is inserted into a shoe to provide magnetotherapy to the wearer's foot adjacent the sole. Collateral therapeutic effects may be effected as such magnetotherapy may affect the nerve endings in the foot and collateral, corresponding, or related tissue structures in the body. A leather upper is used to bear the abrasion between the foot and the magnetic insole. A flexible magnetic core provides alternating magnetic fields in a regular pattern thereby to provide magnetotherapy to the foot. A cushioning base acts as an underpad for the magnetic insole in order to provide greater comfort and cushioning for the user's foot. The flexible magnetic core is constructed by mixing strontium ferrite, barium ferrite, or other strongly ferromagnetic material and with an elastic binder such as neoprene. Additional minor constituents are also added to aid processing.

Abstract: An eye mask or face mask incorporating sources of spatially alternating yet static magnetic fields provides magneto-therapy to the eyes and/or face. In one embodiment, an eye mask is provided that has an opaque eye plate and opaque rearwardly projecting cushion about its perimeter. A sheet of alternating magnetic material provides alternating magnetic fields when travel is made in any direction. The eye mask may be attached to the face by elastic straps or other means which may be adjusted for comfort. The perimeter cushion serves to hold the eye mask away from the eyes and projecting eyelashes of the wearer so that greater comfort is achieved. The opaque nature of both the eye plate and the cushion serves to keep light out, allowing the eyes to enjoy a dark environment, especially appropriate for sleep. The eye mask may be worn during lengthy periods of repose such as sleeping.

Abstract: A Q-damping subsystem for either an NQR or NMR contraband detection receiver for effectively reducing the dead time and increasing sensitivity of the contraband detection system. The invention acts as an addition to the standard transmit circuits of NQR and NMR based scanners and spectrometers. The active Q-damping devices require additional circuitry for an NQR/NMR detection receiver and a programming for the control thereof. Typically, the detection receiver generates a high-voltage RF pulse on the order of 200-1000 V with normal operation of 100-300 microseconds in length to provide sufficient magnetic field characteristics to perturb the precessing nuclei. The NQR or NMR detection receiver electronics are very sensitive and have to detect a very weak nuclear induction pulse signal that is in the nano/micro-volt range.
