  • Publication number: 20110301458
    Abstract: An imaging probe is suitable to be inserted into a tubular object so as to detect an interior image of the tubular object. The imaging probe includes a light source excitation assembly, an ultrasonic transducer and a receiver. The light source excitation assembly includes a pulsed laser, a first optical fiber and a cone-shaped reflecting member. The pulsed laser is suitable to generate a pulsed light energy. The cone-shaped reflecting member is suitable to reflect the pulsed light energy to let the pulsed light energy annularly irradiate the inner wall of the tubular object so as to produce a photoacoustic signal. The ultrasonic transducer is suitable to generate an ultrasonic signal. The ultrasonic signal annularly irradiates the inner wall of the tubular object so as to produce an ultrasonic echo signal. The receiver receives the photoacoustic signal and the ultrasonic echo signal.

  • Publication number: 20110127927
    Abstract: A buck-store and boost-restore converter is to be electrically connected to a pre-stage circuit, which provides a pre-stage output direct current (DC) voltage to a first capacitive load. The converter has an inductance element and is to be electrically connected to a second capacitive load. When the pre-stage output DC voltage is reduced from a first DC voltage to a second DC voltage, the inductance element outputs a current to the second capacitive load so as to transfer electric energy, which is stored in the first capacitive load, to the second capacitive load. When the pre-stage output DC voltage is raised from the second DC voltage to the first DC voltage, the inductance element outputs a current to the first capacitive load so as to transfer electric energy, which is stored in the second capacitive load, to the first capacitive load.
