1230 results about "Vertical angle" patented technology

Vertical Angles. Vertical Angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down.

Lens sheet and method of manufacturing the same

In a lens sheet, a lens portion (3) made of activation energy curing resin such as ultraviolet curing resin has a plurality of lens units, the lens portion (3) is disposed on at least one side of a transparent substrate (2) such as plastic sheet, a relaxation layer (1) is disposed between the transparent substrate (2) and the lens portion (3), and the thickness of the relaxation layer (1) is within a range of 1% to 30% of the height (H) of the lens units. The relaxation layer (1) is made of activation energy curing resin and formed integrally with the lens portion (3). The refractive index of the transparent substrate (2) is lower than that of the lens portion (3). The lens units are elongated prisms each having a substantially triangular cross section. The thickness of the relaxation layer is within a range of 1 mum to 10 mum, for example. The prisms have the vertical angle of 50° to 75° and are arranged with a pitch of 10 mum to 150 mum. The lens sheet having the relaxation layer (1) is obtained by providing activation energy curing composition to an area between a lens portion transferring pattern surface of a lens forming mold and one side of the transparent substrate to form a composition layer between the lens forming mold and the transparent substrate, and making the thickness of the composition layer uniform with use of a nip roll disposed so as to confront the other side of said transparent substrate while nip pressure of the nip roll is regulated by pressure regulating means. Due to the relaxation layer (1), the deformation of the surface of the lens portion caused by polymerization shrinkage of the activation energy curing composition is suppressed so as to prevent occurrence of the optical defect in the lens sheet such as spot pattern, glare, etc.

Light source device

InactiveUS6874902B2Using efficiency of the light amount of a primary light source can be enhancedIncrease brightnessPrismsMechanical apparatusLight guideConvex side
A light source device having a light guide (3) for guiding light emitted from a primary light source and emitting light obliquely from a light emission face (33) thereof, and a light deflecting device (4) disposed so as to be adjacent to the light emission face. Plural elongated prisms are arranged in parallel to one another at a light incident surface (41) of the light deflecting device. Virtual elongated prisms (I) each having a vertical angle θ of 50 to 70° arranged in the same arrangement pitch as the elongated prisms are assumed so that the peak emission light in the light emission distribution of light emitted from the light emission face is incident on one virtual prism face of the virtual elongated prism, internally totally reflected by another virtual prism face and then emitted in a desired direction from a light emission surface (42) of the light deflecting device. A prism face of each elongated prism at the far side from the primary light source is designed to have a convex surface shape with respect to the shape of the virtual elongated prism. The value (r / P) of the radius of curvature r normalized by the arrangement pitch P is equal to 7 to 30, and the ratio (d / P) of the maximum distance between the convex-surface-shaped prism face of the elongated prism and the virtual prism face to the arrangement pitch P is equal to 0.05 to 5%.

Real-time street view navigation method and device

The invention provides a real-time street view navigation method and device. The method comprises the following steps of: sending a navigation route acquisition request including a geographic coordinate of a current position of a terminal and positional information of a destination to a network-side device, and receiving navigation route information generated by a network side; determining the geographic coordinate of the current position of the terminal through GPS (Global Positioning System) information received by the terminal at the current position; transforming the geographic coordinates of all navigation points in the navigation route information into pixel coordinates on a display screen according to the geographic coordinate of the current position of the terminal and a horizontal angle and a vertical angle which are monitored by a sensor of the terminal, and displaying the transformed navigation route information on the display screen of the terminal; and collecting real-time street view of the position at which the terminal is located by an acquisition unit of the terminal in real time during driving and displaying the street view on the display screen, determining the current navigation point matched with the geographic coordinate in the received GPS information in real time from the all navigation points of the navigation route information, and displaying the current navigation point in a displayed navigation route on the display screen.
