  • Patent number: 10505343
    Abstract: The present invention provides an optical transmitter and a light intensity monitoring method that provide reliable APC feedback for a semiconductor laser equipped with an SOA. The optical transmitter includes an SOA integrated EA-DFB having a DFB laser, an EA modulator connected to the DFB laser, and an SOA connected to the EA modulator. In the structure of the optical transmitter, a light detector part is disposed forward of the output end side of an SOA part. The light detector part changes part of an output light beam from the SOA part into an electric current and detects light, while guiding the remaining part of the output light beam to a waveguide. With the light detector part disposed forward for the SOA part, it is possible to feed back the output result from the SOA part. Hence, good APC is possible.

  • Patent number: 7714595
    Abstract: A foreign object detection sensor applied to an electric sliding door apparatus is provided. The sensor includes a contact detecting section, a change detecting section, and a determination section. The contact detection section has a pressure sensitive portion which is capable of elastically changing in form through contact with a foreign object. The contact detecting section outputs a contact detection signal. The change detecting section measures the time required for the oscillation signal for a predetermined number of cycles to be outputted within a measurement period, which is set shorter than the response time it takes from when the object makes contact with the pressure sensitive portion to when the contact detecting section outputs the contact detection signal in the case where the movable body is in the closing operation at a predetermined maximum moving speed.

  • Publication number: 20040169653
    Abstract: In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale.
