  • Patent number: 9289139
    Abstract: A method employed in a prior art arm-worn blood pressure monitor to measure the height position of the heart has been an indirect method that merely estimates the position of the heart, and therefore has had the problems that the measurement accuracy and the reliability of the measurement are low, and that the measuring position is awkward and it is difficult to achieve correct position alignment. An arm-worn blood pressure monitor includes a cuff, a microwave transmitting unit for radiating a microwave onto a human subject, a microwave receiving unit for receiving a reflected wave Doppler-shifted relative to the radiated microwave due to a heartbeat of the subject, and a correct position detector for detecting, based on the reflected wave, whether the cuff worn around an arm of the subject is located in a correct position relative to the position of the heart of the subject.

  • Publication number: 20160070211
    Abstract: Damage caused to a transfer medium due to heat when partially using transfer material regions is suppressed. An image forming apparatus (1) includes a transporting unit (4A, 4B) which transports a belt-like transfer medium (4) on which transfer material regions (Y, M, C, OP) of a first size respectively corresponding to transfer materials are arranged in a predetermined order in a repeated manner along a longitudinal direction thereof, and an image forming unit (3) which transfers the transfer materials in sequence by heating the respective transfer material regions and thereby forms on a recording medium an image with the first size or an image with a second size which is not larger than one half the first size. When forming an image with the second size, the image forming unit either uses unused portions of transfer material regions that have already been used to form an image with the second size or uses new transfer material regions on the transfer medium.

  • Patent number: 9257141
    Abstract: A polarization conversion element includes a phase reversal element and a polarization plane rotation element including a liquid crystal layer. The liquid crystal layer has a plurality of regions disposed along circumferential direction with the intersection point of the polarization plane rotation element and the optical axis as the center with alignment directions different from each other. When electric voltage in accordance with the wavelength of linear polarization incident on the polarization plane rotation element is applied, each region rotates the polarization plane of the polarization component transmitted by each region, and thereby converts linear polarization to radial polarization. The phase reversal element reverses, among the first and the second annular portions alternately disposed along the radial direction with the optical axis as the center, the phase of light incident on the first annular portion relative to the phase of light incident on the second annular portion.
