    Abstract: The present invention discloses a method and apparatus for brain perfusion magnetic resonance imaging (MRI) technique with the removal of cerebrospinal fluid (CSF) pixels. This invention utilizes a CSF/brain-contrast-enhanced image, wherein the CSF/brain-contrast-enhanced image is defined as the signal difference between CSF and brain matter divided by a standard deviation of air background random noise is larger than 3, acquired from the subject's brain, and applies a segmentation technique to remove the CSF pixels. After removing the CSF pixels on parametric images, the extent of brain tissue with delayed perfusion can be better identified. By using a good region of interest enclosing the correct delayed-perfusion region, the measurement on the tissue volume and perfusion parameters would be more accurate than the area contaminated by CSF pixels.

    Abstract: A method for measuring a distance D2 between two points includes following steps. A first surface of a portable electronic device is parallel to a line defined by the two points. A distance D2 between the first surface and the line is obtained. A visible light beam B1 is rotated from an initial direction substantially perpendicular with the first surface and the line to direct at the point E1. A first angle defined by the visible light beam B1 striking the point E1 and the initial direction is computed. A visible light beam B2 is rotated from an initial direction to strike the point E2. A second angle defined by the visible light beam B2 striking the point E2and the initial direction is computed. A distance D1 is computed based on the distance D2, the first angle and the second angle. The distance D1 is outputted.

    Abstract: A switched linear regulator includes a control device with a controlled current path and a control electrode. The current path is connected in series with a source of voltage and a load. An error signal generator compares the load voltage with a reference value to generate a degenerative error signal. The error signal is coupled to the control electrode with a voltage offset. An OFF control signal source includes a transistor which is connected to the control electrode to swamp or overpower the error signal, and render the controlled current path nonconductive. Thus, the same active control element both linearly regulates and provides an ON-OFF function. A speed-up transistor responds to the OFF signal to short the control electrode to a reference voltage to quickly discharge capacitance at the control electrode.
