Abstract: In one embodiment, a charged-particle trajectory measurement apparatus for measuring a trajectory of a cosmic ray muon as a charged particle includes: a plurality of detectors, each of which generates a detection signal at the time of detecting a cosmic ray muon; a signal processing circuit that processes the detection signal from the detector; a time calculator that calculates the generation time point of the detection signal from the detector on the basis of the signal outputted from the signal processing circuit; a trajectory calculator that calculates the trajectory of the cosmic ray muon on the basis of the generation time point of the detection signal and the positional information of the detector having detected the cosmic ray muon, wherein the signal processing circuit and each of the detectors are integrally configured by being coupled to each other.

Abstract: A head mounted display has a display unit to generate a displayed image, an illumination unit to emit illumination light to the display unit, a projection unit to project image light from the display unit, and a light guide unit to transmit image light from the projection unit to pupils of a user. Here, the illumination unit has light source units, a microlens array that is illuminated by light emitted from the light source units and becomes a virtual secondary light source, a condensing optical member to focus light from the microlens array on the display unit, and a diffusion plate to diffuse light from the microlens array, and the diffusion plate is arranged closer to the condensing optical member than to the microlens array. As a result, a conjugate image is inhibited from being generated with the adoption of a microlens array.

Abstract: An optical pickup including a two-wavelength multilaser for generating a tracking error signal and a focusing error signal with high accuracy without light quantity variations which otherwise might be caused by the interference. An optical beam of first wavelength is emitted from first laser light source, and an optical beam of second wavelength longer than the first wavelength is emitted from second laser light source. The optical beams of the first and second wavelength are each split into at least one main optical beam and two sub-optical beams by a grating having, in a single plane, a first grating pattern area for splitting the optical beam of the first wavelength and a second grating pattern area for splitting the optical beam of the second wavelength. The area of the first grating pattern area is larger than the area of the second grating pattern area.

Abstract: A disposable excreta management device has a longitudinal centerline and a transverse centerline, and comprises a flexible bag to contain excreta and an adhesive flange to attach the device to the body of the wearer. The flexible bag has a wearer facing portion and a garment facing portion. The wearer facing portion has an opening surrounded by the adhesive flange. The disposable excreta management device is characterized in that expansibility of the garment facing portion of the flexible bag is greater than that of the wearer facing portion of the flexible bag when the flexible bag contains excreta.
