In a system and method for analyzing and treating a body lumen, a lumen-expanding balloon catheter with integrated one or more delivery waveguides and one or more collection waveguides is used to perform optical analysis of the tissues surrounding the lumen during expansion. The catheter can comprise an angioplasty catheter with integrated delivery waveguides and collection waveguides to perform spectroscopy of a stenotic plaque during angioplasty.

An automatic charging station for an autonomous mobile machine includes a base, a housing, and a signal transmitter. The base is mounted on the ground or on a planar surface. The housing is rotatably mounted on the base, having at least one guide member and a plurality of electrically conductive members on a surface thereof. The electrically conductive members are located on the housing. The signal transmitter is mounted on the housing for transmitting a signal. When the autonomous mobile machine senses the signal transmitted by the transmitter while moving, the autonomous mobile machine moves along a route towards the housing and then forces the guide member to enable the housing to rotate for facing and accommodating the autonomous mobile machine and to further enable the autonomous mobile machine to contact against the housing to have its electrodes in contact with the electrically conductive members for charging.

This invention relates to an electrophoretic display comprising cells of well-defined shape, size and aspect ratio, which cells are filled with charged pigment particles dispersed in a solvent, and novel processes for its manufacture.

An antenna, including a planar dielectric substrate and a conductive ground plane formed on the substrate. A conductive monopole is formed on the substrate and has an end point located in proximity to a feed region of the ground plane. A conductive coupling element is formed on the substrate and is coupled to the ground plane at a coupling region of the ground plane. The coupling element is folded around the monopole.

A head-mounted display system comprises: a display device freely detachable and attachable on a user's head; a direction detector for detecting the orientation of the user's head in at least the horizontal direction, the direction detector being disposed on the display device; an image generator for generating an image in accordance with the orientation of the user's head detected by the direction detector; a displacement-calculating unit for calculating displacement, the displacement being the difference between directional data of the current orientation of the user's head detected by the direction detector and directional data of the orientation of the user's head detected a predetermined amount of time ago; and an image processor for sending an image generated in the image generator to the display device after shifting the image in at least the horizontal direction in accordance with the displacement calculated by the displacement-calculating unit.

An optical probe includes a tubular outer envelope and a optical fiber which extends in the longitudinal direction of the outer envelope inside the outer envelope. By fixing a light deflecting element to the optical fiber and rotating the optical fiber by a driver, the light deflecting element is rotated. A protective member which has a higher resistance to wear than the outer peripheral surface of the optical fiber is fixed to a part of the outer peripheral surface of the optical fiber in a position near the front end of the optical fiber and is borne for rotation by a bearing portion on the probe outer envelope.

An optical tracking system can include at least one scanning detector having a scanning mirror and one or more fixed photo-detectors located near the scanning mirror. The scanning mirror can be configured to deflect a light beam from a source towards a retroreflective target and the photodetectors are configured to collect a portion of the light beam that is retroreflected from the target. A scanning optical detector apparatus may optionally comprise a substrate, a scanning mirror having at least one portion monolithically integrated into the substrate, and one or more photodetectors monolithically incorporated into the substrate.

A freeze indicator employs, as active indicator element, dispersion of solid particles in a liquid medium which can be water or aqueous and which coagulates to provide an irreversible appearance change when subject to freezing. The liquid dispersion can be contained in an indicator volume around which extends a vapor block layer. The vapor block layer can prevent loss of liquid vapor from the dispersion and consequent drying out and dysfunctionality of the freeze indicator. For containing an aqueous medium, bilayer and trilayer laminate materials can be used which have a low water vapor transmission rate. The active indicator element can be a dilute colloidal dispersion of a metal such as gold or silver or other inorganic pigment material in water or an aqueous medium. Some embodiments avoid use of dispersants and the like and employ an active indicator element consisting of inorganic pigment particles, water and optionally an ice nucleating agent. Heavy water, or deuterated water can be components of the water, if desired.

The present invention relates to microfluidic devices and to their method of manufacture. The microfluidic devices are original by their specific structure (of sandwich type) and by the materials from which they are made (mainly glasses, glass ceramics, ceramics), and also by their specific method of manufacture, which is based on a vacuum-forming operation. The microfluidic device includes a first assembly including a microstructure and a first substrate, wherein the microstructure is constructed and arranged on the substrate under vacuum. A second assembly includes a second substrate positioned on the microstructure after the first assembly is presintered and adhered thereto by heat treatment to form a one-piece microstructure defining at least one recess between the first and second substrates.

The present invention discloses a metallic nanowire-graphene bridge structural composite material which comprises multiple layers of grapheme and metallic nanowires and is characterized in that the metallic nanowires are arranged at one side or two sides of the surface of a grapheme sheet layer, the metallic nanowires are welded to the metallic nanoparticles at the surface of the grapheme, and a metallic nanowire-graphene bridge structural composite material is formed. According to the composite material, the transmittance is larger than 85% to 92%, the surface resistance is smaller than 1 Omega at the same time, in an optimal embodiment, a transparent conductive film with the transmittance larger than 90% and the surface resistance smaller than 1 Omega is realized, and the current and future industrial application requirements are fully satisfied. Through growing the metallic nanoparticles with proper density at the surface of the single-layer or few-layer grapheme and assembling and welding the metallic nanowires (such as silver nanowires and copper nanowires) on the metallic nanoparticles, grapheme-metallic nanowires are formed and are assembled and processed to form a grapheme-metallic nanowires bridge structure, a transport path is provided for electrons, and thus the surface resistance of a grapheme assembly film is greatly reduced.

A pair of through-holes 41a and 41b having the same shape are formed and aligned in a flexible board 4 on which a wiring pattern 42 is formed. A piezoelectric actuator 3 made of a piezoelectric bi-morph device is inserted into the first through-hole 41a and then into the second through-hole 41b from the opposite surface side. As a result, both the ends in the longitudinal direction of the piezoelectric actuator 3 contact the same surface of the flexible board 4. The flexible board 4 is disposed so that it contacts a touch sensor portion except for a part of the flexible board 4. Thus, a high performance force sense feedback function caused by the panel that deforms corresponding to an input operation can be accomplished at low cost.
