Abstract: A combined systems user interface (CUI) may be configured with an advanced technology screening checkpoint (ATSC), which is a passenger-friendly, high performance system for screening passengers and carry-on items to detect assembled bombs, bomb components, metallic and non-metallic weapons, and other contraband items. The CUI may include a baggage, passenger, and secondary screening status regions. The baggage screening status region displays screening information generated by an explosives screening system and a baggage imaging system, while the passenger screening status region displays screening information generated by an explosives detection portal and a metal detection portal. In some implementations, a secondary screening status region displays screening information generated by a body scanning system and an enhanced explosives screening system.

Abstract: A new and improved leg assisted forward facing rowing system is disclosed wherein a rower applies leg power to propel a boat by means of a rope connected between his or her foot and an oar. A unique feature is a roller, fastened under the heel of the rower's foot, that rolls along the bottom of the boat supporting the weight of the rower's leg while the reciprocating motion of the leg is transmitted by rope going through pulleys to reverse the force applied to the oar. The oar is pivoted at the center of the boat above the rower's knees by a mechanism that includes provision for applying lifting force to support the oar weight thereby holding the oar blade out of the water when no force is applied. The rower's legs, back and arms simultaneously apply rowing force. Feathering at the end of a stroke and squaring action at the beginning are provided by wrist action to rotate the oar blade.

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: Techniques for producing and manipulating magnetic fields. The techniques employ the mutual repulsion of magnetic fields to create uniform magnetic fields and to manipulate the uniform magnetic fields. The uniform magnetic field is created between two planar magnets. The planar magnets have cores which describe a closed curve. Like poles of the electromagnets are connected by the cores. When the electromagnets are activated, repulsion between the magnetic fields generated by the electromagnets creates a magnetic field which extends above and below the planes of the planar magnets. If the planar magnets are positioned parallel to each other and aligned so that the magnetic fields generated by the planar magnets repel each other in the space between the planar magnets, the repulsion between the fields generates a resultant field.

Abstract: The linear synchronous motor consists of a specific primary and secondary part. The secondary portion is a ferromagnetic back plate. An array of permanent magnets are attached to the back plate so that a fixed or variable pole pitch occurs in a precise manner between at least two magnets of alternating polarity which improves existing methods for attaching, guiding, protecting and enhancing the overall flux array produced and emitted by the permanent magnets. A one-piece electrically synchronous linear secondary stator member accompanies a primary member, the synchronous linear permanent magnet motor. The stator electrical frequency is customizeable to allow for a wide variety of braking applications.

Abstract: An explosives detection system which includes computed tomography (CT) and quadrupole resonance (QR) sensors for identifying particular explosive compounds present in passenger baggage. The CT sensor may be configured to automatically identify the presence or absence of bulk military, commercial, and sheet explosives during CT scanning of the baggage. Similarly, the QR sensor may be configured to responsively generate RDX and PETN signals during QR scanning of the passenger baggage. Using any of a variety of inspection protocols, the explosives detection system may generate an output alarm based upon data obtained from the CT and QR sensors.

Abstract: A magnetic insole provides cushioned 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 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.

Abstract: An inspection system including a radio frequency (RF) subsystem and a quadrupole resonance (QR) tube array coil. The RF subsystem may include a variable frequency RF source to provide RF excitation signals at a frequency generally corresponding to predetermined, characteristic QR frequencies of a specimen. The QR tube array coil may be implemented using a plurality of conductive tubes defining a cavity of predetermined volume. Typically, the plurality of conductive tubes are spaced at a distance relative to one another to form at least two non-conductive gaps between tubes in the array. After RF excitation signals are applied to the specimen within the cavity, the QR tube array coil may generate a QR output signal responsive to QR signals generated by the specimen.

Abstract: An impeller and at least a portion of a cooperating peripheral volute may be integrated into, and preferably are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless d.c. motor with low length (L) to diameter (D) ratio and suitable for use in a variety of other applications. In one practical embodiment of such a motor, a rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a permanently magnetized ring shaped rotor magnet having a number of poles of alternating polarity defined about its inner circumference and separated by a relatively small cylindrical air gap from the outwardly projecting radially oriented selectively magnetized poles of a fixed stator assembly. In one exemplary embodiment, the rotor may have 8 poles and the stator may have 9 poles.

Abstract: Techniques used in systems that employ pairs of coils arranged around an axis to make a magnetic field that rotates around an axis to reduce or eliminate the effects of corners where adjacent ones of the coils meet on the uniformity of the magnetic field. The techniques are particularly useful in plasma reactors that employ magnetically-enhanced reactive ion etching technology. The techniques employ elements that are low cost and may be easily retrofitted to existing plasma reactors. The elements include magnetic shunts that are fitted to the corners of the coils to compensate for the corner effects, trim coils fitted to the corners that, when energized, compensate for the corner effects, and sets of coils that function as 180° coils and thereby reduce the corner effects. The magnetic shunts may be combined with the trim coils.

The device places the sensor arrays in close proximity to a subject's body, including the head and feet if desired, for screening purposes. The portal can have multiple excitation sources oriented to generate a multi-axis excitation field, and multi-axis sensors. The portal can also have an interlock with the door of the controlled area.

Abstract: A Reciprocating Generator Wave Power Buoy consists of a reciprocating generator rigidly attached to the underside of an ocean buoy and creates electric power from the surface ocean swells. The generator coil maintains a stable position beneath the ocean surface while the magnetic field housing reciprocates with the vertical motion of the buoy in response to interaction with swell and waves on the surface of the ocean. Damping plates attached to the generator coil inhibit the motion of the generator coil, thus keeping it in a stable position relative to the motion of the magnetic housing. The magnetic housing focuses the magnetic field through the generator coil and the relative motion between the magnetic housing and generator coil creates an electromotive force in the coil. The design of the generator provides a uniform field of single magnetic orientation throughout the entire stroke of the generator.

The portal has at least one excitation coil oriented to cause the excitation field to have zero mutual inductance with the gradiometers.

Abstract: Magnet spirals for therapeutic application with a minimum one foil strip made of a rubber-type flexible, preferably skin compatible, plastic which is coiled up along its lengthwise dimension in the form of a spiral, whereby the foil strip is magnetically polarized in an axial (perpendicular) direction relative to its longer lateral faces prior to coiling. The longer lateral faces of the foil strip are magnetically polarized in an axial direction of the foil—that is, in the thickness direction of the foil strip, preferably up to its total saturation. In the coiled condition of the foil, one side of the lateral area thus faces the other side of the 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: Flexible and elastic magnetic joint wraps incorporate superstrong magnets with alternating polarities to provide enhanced magnetotherapeutic effects. Magnetotherapeutic joint wraps that are flexible and elastic incorporate superstrong magnets in an attachably detachable manner so as to provide magnetotherapy to joints and surrounding tissues. NEOPRENE® or the like may incorporate superstrong magnets such as those based on iron (magnetic ferrite) or neodymium (particularly neodymium-iron-boron (NdFeB)) in order to provide superstrong static magnetism by which magnetotherapy may be effected. Elements that are generally oppositely opposed serve to detachably attach portions of the magnetic wrap to one another so that the magnetic joint wrap may conform to the local shape and form of the area adjacent the joint. Such attachment elements may include VELCRO® hook and loop fasteners as well as buttons, snaps, and the like.
