摘要： Radio frequency (RF) shields used with magnetic resonance imaging (MRI) apparatus may experience gradient field induced eddy currents and RF field induced eddy currents. These eddy currents can cause the RF shield to heat up at an undesirable rate. RF shields are designed to have a desired degree of RF shielding and a desired heating attribute. Design goals for RF shields include gradient field transparency and RF field opacity, both of which can be influenced by eddy currents. Example methods identify a gradient field that will induce eddy currents and identify an RF field that will induce eddy currents. If a region on the RF shield is identified where the desired heating attribute will not be achieved, then a pattern of axial cuts and azimuthal cuts can be made in the RF shield to reduce gradient eddy current heating in the RF shield while maintaining desired RF shielding.

摘要： The present invention provides an apparatus for reducing acoustic noise in a magnetic resonance imaging device including passive shielding located outside the actively shielded gradient winding elements in order to reduce the magnitude of fields that spread outside the gradient coil assembly in unwanted directions and interact with the magnet cryostat or other metallic magnet parts, inducing eddy currents that cause consequent acoustic noise. The passive shielding elements are conducting layers located on the outer radius of the cylindrical gradient coil assembly in a cylindrical magnet system, conducting layers located at the ends of the gradient coil assembly in a cylindrical magnet system, and conducting layers located inside the actively shielded gradient winding inner elements in a cylindrical magnet system. The passive shielding could also be located on separate structures that are vibrationally isolated from the magnet cryostat. The actively shielded gradient winding can also be extended to portions at the ends of the actively shielded gradient winding and further to portions inside the inner radius of the inner portion of the actively shielded gradient winding. The actively shielded gradient windings and passive shielding should be designed concurrently in order to substantially optimize the gradient linearity and reduce the eddy currents generated in metallic parts of the magnetic resonance imaging system.

摘要： In a magnetic resonance imaging apparatus, a main magnet assembly (12) produces a uniform magnetic field through an imaging region (14). An imaging region is defined within a subject by selecting gradient magnetic fields spatially encode the main magnetic field. A whole body birdcage radio frequency coil (26) excites magnetic resonance in dipoles of the subject. The resonance signals are received by the whole body coil (26) and by a second, local birdcage radio frequency coil (16). The first radio frequency coil (26) produces and is sensitive to a uniform radio frequency field in the imaging region (14) while the second radio frequency coil (28) is sensitive to a field that varies sinusoidally in space. From one radio frequency excitation, the two birdcage coils (26, 16) receive different sets of data with which to fill k-space, accelerating data collection.

摘要： An electrical connector (1, 1′) straddle-mounted on an edge (20, 20′) of a printed circuit board (2, 2′) includes an insulative housing (10) having an elongated groove (11) for mating. A number of receiving channels (13) each used to receive a support subassembly (3, 3′) is formed adjacently to and communicated with the mating groove (11). The support subassembly includes a base (30, 30′) with signal terminals (5, 5′) and a grounding member (4, 4′) attached thereon. Every terminal includes an engaging end (51, 51′) exposed to the mating groove (11) and a tail end (52, 52′) extending out of the receiving channel (13). The grounding member includes a number of contacting legs (42, 42′) extending therefrom. A notch (34, 34′) with a thinned area is disposed on the base to define a separating portion (33, 33′) from the base. The notch is used to facilitate relocating the separating portion relative to the base. The separating portion of the base can be positioned between the tail ends of the terminals and the contacting legs of the grounding member to electrically insulate them from each other while the shape of the tail ends and the contacting legs are changeable for being mounted on another desired printed circuit board with a different thickness. The separating portion can be moved for the assembling of every terminal and the grounding member when they need to put together to form the support subassembly for being inserted into the housing.

摘要： An electrical connector (1) includes an insulative housing (10) and a number of contacts (28) attached to the housing. The contacts each have a contact tail (36) downwardly extending beyond a mounting surface (32) of the insulative housing for inserting into throughholes (42) of a PCB (40). The contact tails are overlapped in pairs and each pair of contact tails is inserted into the same throughhole of the PCB. Some pairs of contact tails, called retention contact tails (68), have protrusions (52) deviating from each other for bearing against peripheral walls of the throughholes of the PCB thereby producing retention force. The other pairs of contact tails, called non-retention contact tails (70), do not have protrusions and do not interfere with peripheral walls of the other throughholes thereby reducing the insertion force. The retention contact tails can be modified to the non-retention contact tails by severing the protrusions therefrom.

摘要： A modular storage system for cylindrical objects, such as rolled carpet mats, having an open frame in the form of a right parallelepiped comprised of a horizontal rectangular base, a horizontal rectangular top, and vertical standards connecting the corners of the base and top. Within the frame there are disposed a plurality of pairs of left and right face-to-face vertically extending abutting mirror image formed or shaped shells. Each mirror image shell is formed to define a plurality of alternating inwardly facing one-half storage cells separated by oppositely facing one-half storage cells of substantially identical shape and cross-section. Each abutting pair of face-to-face shells forms a composite unit and defines a vertical row of spaced apart horizontal storage cells. Each adjacent abutting composite unit defines a vertical row of similar horizontal storage cells in staggered relation to the first row. The composite units substantially fill the space within the open frame and are supported by the frame top and base. Although the storage cells are preferably of hexagonal cross-section they may alternatively be of square cross section arrayed either horizontally or diagonally.

摘要： A machine (50) is disclosed that assembles an electrical connector (10) to the edge (18) of a printed circuit board (12). The machine incorporates an actuating mechanism that requires only a single input motion to achieve a Variety of functional motions within the machine. The machine includes a carriage assembly (54) that moves substantially vertically within the frame of the machine to sense the thickness of the circuit board and then to align the centerline of the connector held on fixture (280) with the exact center plane (44) of the board. A slide member (140) then moves toward the connector, causing a pair of comb members (252, 254) to close into position in front of the moving connector. The solder tails (38,40) of the connector (10) then enter spaced slots (260) in the edges of the comb members for support and the connector housing engages the face (272) of the combs, pushing them toward the circuit board. Angled free ends of the solder tails (38, 40) of the connector then engage the corners of upper and lower board surfaces (14, 16) at the board edge (18), and the center row of ground bus posts (32) are forced into apertures (26) in the edge of the board by a pusher member (174) until they contact plated through holes (24) in the board while the outer rows of tails cam out to and bear against and along the two opposite major board surfaces and into contact with solder pads thereon.
