摘要： A motor and fan structure 10 includes direct current motor assembly 18 having a stator assembly 20 including a flux plate 22 and permanent magnet structure 24 mounted on the flux plate 22. The flux plate 22 defines one end of the motor assembly and define a magnetic flux path of the motor assembly. The motor assembly also includes a generally cylindrical armature assembly 32 defining another end of the motor assembly. The armature assembly is radially wound with windings 40, and an outermost part of the armature assembly and at least a portion of the windings is exposed to the environment. The structure includes a fan 12 having a generally cylindrical hub 14 receiving and covering the outermost part and the portion of the windings of the armature assembly. The hub 14 has a plurality of blades 16 extending therefrom. Thus, the weight and axial length of the motor assembly can be reduced since no case is required to cover the armature assembly yet the armature assembly is protected by the fan hub.

摘要： Systems and methods for breast x-ray tomosynthesis that enhance spatial resolution in the direction in which the breast is flattened for examination. In addition to x-ray data acquisition of 2D projection tomosynthesis images ETp1 over a shorter source trajectory similar to known breast tomosynthesis, supplemental 2D images ETp2 are taken over a longer source trajectory and the two sets of projection images are processed into breast slice images ETr that exhibit enhanced spatial resolution, including in the thickness direction of the breast. Additional features include breast CT of an upright patient's flattened breast, multi-mode tomosynthesis, and shielding the patient from moving equipment.

摘要： A method of linking commutator bars of a commutator for a motor wherein N is the number of magnetic poles of the motor and N is an even integer greater than 2. The method include a) arranging a plurality of commutator bars to be generally equally spaced in a circular arrangement to define the commutator, each commutator bar having a tang extending therefrom, b) contacting an end of a continuous, insulated conductive member to a tang, c) moving the member to contact a second tang which is disposed at an angle of 720°/N from the previously contacted tang to form a link, and when N is greater than four, repeating this step until N/2−1 links are created, d) moving the member to contact a tang which is immediately adjacent to the second tang contacted in step (c) such that the member defines a bridging portion between the adjacent tangs, e) repeating steps (c) and (d) and until all tangs have been contacted by the member, and f) cutting the bridging portion between adjacent tangs.

摘要： A choke 10, for suppressing radio-frequency interference of a brush-type motor, includes a single wire having a portion 15 wound about a coil axis A to define a plurality of coils 14 including two outermost coils 16 and 18. An attaching structure 20 extends from each outermost coil and is disposed generally transverse with respect to the coil axis. Each attaching structure is constructed and arranged to be inserted through an associated opening in a supporting structure and to be bent so as secure the choke to the supporting structure. An elongated end portion 22 extends from each attaching structure so as to be spaced from and generally parallel to the coil axis. The elongated end portions extend in opposite directions. One of the elongated end portions is constructed and arranged to be directly electrically connected to an electrical connector of a motor and the other of the elongated end portions is constructed and arranged to be in electrical connection with a brush of the motor.
