20080239771 | Asymmetrical Interleaving Strategy for Multi-Channel Power Converters - In a power converter having m=two or more channels of power factor correction (PFC) circuits connected in parallel and an electromagnetic interference (EMI) filter connected in series therewith, phase shifts in switching between the respective PFC channels can allow increase of EMI filter corner frequency allowing reduction of size and cost of the EMI filter at some switching frequencies. Asymmetrical phase shifts (other than 360°/m) such as 360°/2m and other phase shifts and variations in m allow increase of EMI filter corner frequency at switching frequencies where symmetrical, 360°/m phase shifts provide no benefit to EMI filter design by providing cancellation or partial cancellation of different harmonics of the switching noise; which cancellation may be arranged to be complementary to the EMI filter function at more than one peak of the noise spectrum. (Such asymmetrical phase shifts do not significantly increase ripple and consequent switching noise). Alteration of m and corresponding alteration of phase shift may be performed adaptively for purposes of improving efficiency at light loads and the like. | 10-02-2008 |

20100202583 | Systems and Methods for Exact or Approximate Cardiac Computed Tomography - A computed tomography (CT) system has a composite scanning mode in which the x-ray focal spot undergoes a circular or more general motion in the vertical plane facing an object to be reconstructed. The x-ray source also rotates along a circular trajectory along a gantry encircling the object. In this way, a series of composite scanning modes are implemented, including a composite-circling scanning (CCS) mode in which the x-ray focal spot undergoes two circular motions: while the x-ray focal spot is rotated on a plane facing a short object to be reconstructed, the x-ray source is also rotated around the object on the gantry plane. In contrast to the saddle curve cone-beam scanning, the CCS mode requires that the x-ray focal spot undergo a circular motion in a plane facing the short object to be reconstructed, while the x-ray source is rotated in the gantry plane. Because of the symmetry of the mechanical rotations and the compatibility with the physiological conditions, this new CCS mode has significant advantages over the saddle curve from perspectives of both engineering implementation and clinical applications. | 08-12-2010 |
