Abstract: A battery monitoring device includes: a pair of terminals for measuring voltage or current of a battery, and to which a filter unit including a capacitive element is connected; an AD converter that measures a waveform of voltage between the terminals during charging or discharging of the capacitive element; and a time constant calculation unit that calculates a time constant of the filter unit based on the waveform measured. The AD converter is, for example, a first AD converter or a second AD converter. The filter unit is, for example, a first filter unit or a second filter unit.

Abstract: A packaged acoustic wave filter component can include an acoustic wave device including a first piezoelectric layer and an interdigital transducer electrode on the first piezoelectric layer. A support layer may be included over the acoustic wave device, and the packaged hybrid filter component can also include a bulk acoustic wave resonator over the support layer. A cap layer may extend over and encapsulate the bulk acoustic wave resonator. One or more external vias may extend through the support layer and the underlying layers of the acoustic wave device to provide electrical communication with the packaged bulk acoustic wave generator.

Abstract: An acoustic wave device includes a piezoelectric substrate, interdigital transducer electrodes including a predetermined number of electrode fingers disposed on an upper surface of the substrate, and a dielectric material layer having a first portion and a second portion. The first portion is disposed on the upper surface of the substrate and between the interdigital transducer electrode fingers. The second portion is disposed above the interdigital transducer electrode fingers. The acoustic wave device further includes at least one thermally conductive bridge disposed within the dielectric material layer and contacting upper surfaces of at least two adjacent interdigital transducer electrode fingers to dissipate heat therefrom.

Abstract: An acoustic wave filter component can include a surface acoustic wave device including a first piezoelectric layer, an interdigital transducer electrode on the first piezoelectric layer, and an additional layer, such as a temperature compensation layer, over the interdigital transducer electrode. The acoustic wave filter component can also include a bulk acoustic wave resonator supported by the additional layer. The additional layer may be a layer on which a surface acoustic wave of the surface acoustic wave device will propagate. The bulk acoustic wave resonator may include an air cavity, where a shape of the air cavity is defined in part by the additional layer.

Abstract: A radiography apparatus sequentially determines, on the basis of the positions of markers as time-sequential feature points (of a plurality of frames), positions at which the markers in the frames are displayed. This makes it possible to display a moving object while the position, direction and size thereof are properly set. Another advantage is that when a plurality of markers are extracted, information relating to the direction and size of the object is retained and the proximal and distal directions of the object and the length of a device (e.g., stent) can be intuitively determined from an image. Since positioning is performed using the plurality of positions of markers and the plurality of display positions, the position and direction of a corrected image to be finally displayed can also be set properly.

Abstract: An X-ray imaging apparatus includes an X-ray tube (1), an FPD (2), a holding unit (4) that holds the X-ray tube and the FPD, which face each other, a table (3) on which a subject is placed, and a control unit (5) that controls the movement of the holding unit so as to control an X-ray irradiation direction of the X-ray tube and an X-ray detection direction of the FPD in an interlocking response with a relative position of the table to the X-ray tube and the FPD or based on an operation during X-ray imaging, when the X-ray imaging apparatus performs the X-ray imaging while relatively moving the table with respect to the X-ray tube and the FPD.

Abstract: [Purpose] To provide a radiographic imaging apparatus capable of quickly acquiring three-dimensional image data of a target-of-interest when performing an operative procedure such as interventional treatment [Solving Means] A region-of-interest extraction unit 39 extracts a predetermined region as a region-of-interest from each of a series of two-dimensional images. The reconstruction unit 41 reconstructs a three-dimensional image of a region including a stent based on each of the images of the portion corresponding to the region-of-interest. That is, since the reconstruction unit 41 reconstructs each of a series of two-dimensional images P using an image of the region-of-interest corresponding to a part of the whole, the time required to reconstruct the three-dimensional image of the region including the stent can be shortened.

Abstract: An exhaust system apparatus for an engine includes an exhaust conduit member, which is connected to the rear face of the engine body, and a heat shield member, which covers the exhaust conduit member. The heat shield member has a curved-side body portion, which covers a curved portion of the exhaust conduit member, an inner flange portion, which extends from the curved-side body portion and is arranged in the region on the inner peripheral side of the curved portion, and an outer flange portion, which extends from the curved-side body portion and is arranged in the region on the outer peripheral side of the curved portion. The extending length of the inner flange portion in a direction away from the curved-side body portion is longer than the extending length of the outer flange portion in a direction away from the curved-side body portion.

Abstract: An X-ray tube and a flat panel X-ray detector (FPD) are constructed movable parallel to each other in the same direction along a body axis which is a longitudinal direction of a patient. The X-ray tube intermittently emits radiation and the FPD detects radiation transmitted through the patient irradiated intermittently whenever the X-ray tube and FPD move every pitch. X-ray images O1, O2, . . . , OI, . . . , and OM are decomposed for every pitch noted above. The decomposed images are composed for each projection angle to obtain projection images P1, P2 and so on. Therefore, a sectional image with a long field of view in the longitudinal direction can be obtained by carrying out a reconstruction process based on the composed projection images.
