  • Patent number: 9518708
    Abstract: A lighting apparatus includes a plurality of LEDs arranged in a row; an elongated wiring board on which the LEDs are mounted; and an optical lens covering all the LEDs and controlling distribution of light emitted from each LED. The light emitted from each LED has an optical axis orthogonal to the wiring board. The optical lens is a converging lens and includes a first light incident surface on which the light emitted from the LED is incident, a medium that guides the light incident from the light incident surface, a light emitting surface, and a diffusion section that contains diffusing particles for causing the light incident from the LED to diffuse. The concentration of the diffusing particles in the diffusion section is high in the vicinity of the optical axis of the light emitted from the LED and gradually decreases as a distance from the optical axis increases.

  • Publication number: 20160159366
    Abstract: A driving assistance system includes a history storage unit, a behavior detecting unit, a state determining unit, and a notifying unit. The history storage unit stores a behavior history which is a past behavior history of a driver. The behavior detecting unit detects a current behavior of the driver. The state determining unit determines an unsafe state by comparing the transition of the behavior detected by the behavior detecting unit with the behavior history of the driver corresponding to a current driving path. If the state determining unit determines the unsafe state, the notifying unit gives notification to the driver.

  • Patent number: 9361022
    Abstract: A plurality of characters that are candidates for entry are displayed on a display surface of a display corresponding to an operation surface of a touch panel as character buttons. A touch detector judges whether a user touches the operation surface either with a single point or plural points, and detects a position touched by the user. An input receiver receives an entry of a character associated with a character button in the position touched by the user among the plurality of characters displayed on the display surface of the display. Then, the input receiver receives the entry of the character which varies in type depending on whether the user touches an area in the operation surface corresponding to an identical character button with a single point or plural points.

  • Patent number: 9310046
    Abstract: A light emitting module includes a surface emitting panel and an optical member located at the light emitting surface side of the surface emitting panel. The surface emitting panel has a light emitting region and a non-light emitting region. The optical member has a reflector in the region corresponding to the light emitting region. The reflector has a reflectivity distribution in which the average reflectance per unit area varies. According to this configuration, light emitted from the surface emitting panel and guided by the optical member is reflected by the reflector and emitted in front of the non-light emitting region. By this way, a region in front of the non-light emitting region is difficult to be dark, thus allowing the light emission area to be increased. Further, where a number of light emitting modules are arranged in a matrix as a lighting device, a uniform illumination surface is provided.
