Patent number: 6922580Abstract: A magnetic resonance imaging method and apparatus includes a navigator region defined within the subject by selective excitation. Blood flow is measured within the selected region using the principles of phase contrast MR angiography. A cardiac cycle plot is constructed from Fourier transformed data that represents measured velocity of blood flow through the navigator region as a function of time. On the basis of the cardiac cycle plot and the navigator measurements, data acquisition is synchronized or gated to portions of the cardiac cycle.Type: GrantFiled: June 4, 2002Date of Patent: July 26, 2005Assignee: Koninklijke Philips Electronics N.V.Inventors: Gordon D. DeMeester, Kecheng Liu

Patent number: 6784781Abstract: An improved reactor and ballast system is provided. The reactor includes a core having an I portion and a rolled portion which forms a core opening, a coil having an electrically insulated coil opening through which the I portion extends, and a spacer between the I portion and an edge of the rolled portion of the core. A portion of the coil extends into the core opening. The ballast system includes a core having a plurality of I portions and a rolled portion which form one or more core openings, a plurality of coils, each coil having an electrically insulated coil opening through which one of the I portions extends, and a plurality of spacers between the I portions and a first edge of the rolled portion and between the I portions and a second edge of the rolled portion. A portion of each coil extends into a corresponding core opening.Type: GrantFiled: April 8, 2003Date of Patent: August 31, 2004Assignee: General Electric CompanyInventors: Byron R. Collins, George E. Kiefer

Patent number: 6225621Abstract: A laser diode (22) emits laser light which is collimated into parallel rays with collimating lens (24). The collimated beams travels as much as 50 meters or more before being reflected back to a photoreceiver (28). A ball lens (26) focuses the reflected light onto the photoreceiver. The photoreceiver, preferably, is a synchronous detector which issues control pulses to a laser drive circuit (42) for causing the laser diode to emit intermittent bursts of laser light. The synchronous detector then compares the timing of received light with the timing of the control pulses to the laser diode to distinguish between true reflected light and stray light. An intensity adjustment (56) adjusts the intensity of the laser light in accordance with a distance between the laser diode/photoreceiver and a reflector. In this manner, distances of 1-70 meters can be accommodated with no lens modification.Type: GrantFiled: May 7, 1999Date of Patent: May 1, 2001Assignee: Automatic Timing & Controls, Inc.Inventors: John D. Rogers, Steven H. Mersch

Patent number: 6177751Abstract: The object of the present invention is to provide a rotary electric machine that provides bobbins with good assembling efficiency and allows no dislocation of the stator. A motor 2 comprises a case 4, a stator 6 secured inside the case 4, a rotor 10 formed into one piece with a rotating shaft 8. The stator 6 comprises stator yokes 32 and the stator yokes are secured in a radial manner in the case 4. Furthermore, resin 58 is filled in between the stator 6 and the case 4 with a space for the rotor being left. The stator yokes 32 comprise a salient pole 34, a bobbin 36 for holding the salient pole 34, and a magnetic wire 38 wound around the bobbin 36. A collar 39b of the bobbin 36 is formed so as to contact each other with notches 3 formed on two, upper and lower edge portions. Accordingly, combining two bobbins 36, 36 allows through-holes 5 penetrating the collar 39b thereof.Type: GrantFiled: August 20, 1999Date of Patent: January 23, 2001Assignee: Minebea Co., Ltd.Inventors: Yuzuru Suzuki, Sakae Fujitani, Kunitake Matsushita, Takayuki Yamawaki, Hiroshi Sano, Kazuo Muramatsu, Taichi Nishio

Patent number: 6099115Abstract: The ink reservoir comprises a bottle (1) into which is installed a foil bag (2). The bag (2) is designed at both axial ends as a standing bag. In one end of the bag (2) includes a thermoplastic connector (23) having an elastomer stopper (27) disposed therein. The stopper is piercable by a first hollow needle of the plotter. The connector (23) is snapped into a lid (4) of bottle (2) below a passage opening (44). The lid (4) is snapped onto the bottle (1). Below the lid (4), an absorbent body (3) is installed in the bottle (1) which surrounds the bag. By means of another opening (45) in lid (4) a second hollow needle of the plotter is inserted into the absorbent body (3). The absorbent body serves for acceptance of waste ink. With the described design, one attains simple handling during shipping and installation in the plotter.Type: GrantFiled: March 16, 1998Date of Patent: August 8, 2000Assignee: Pelikan Produktions AGInventor: Francisco Faoro
