摘要:
A safety device for a power window is achieved, which considers variation in capacitance during raising of a window glass, and considers variation in capacitance due to a use situation so as to reduce a possibility of false operation.The safety device has a window position counter that allows repetitive pulses to be generated depending on amount of rotation of a raising/lowering motor that raises or lowers a window glass, and counts the pulses to acquire opening information of the window glass; a storage unit that detects capacitance of an electrode provided on the window glass during raising of a window glass, and stores change in the capacitance with being related to window position information given by the window position counter; and a controller that sets a reversal threshold value with the stored change in capacitance, which is stored in the storage unit with being related to the window position information, as a reference, and reverses the raising/lowering motor to lower the window glass irrespective of a state of the operational switch in the case that a value of capacitance detected by a capacitance detector during raising operation of the window glass exceeds the reversal threshold value for each window position information.

An optical module includes a substrate, one or a plurality of planar optical devices mounted on the substrate, and a waveguide block including one or a plurality of curved waveguides formed on a plane. The waveguide block is mounted on the substrate such that the plane on which the curved waveguides are formed is perpendicular to the substrate and the curved waveguides and an incidence face or an emitting face of the planar optical device are opposed to each other on one end face of the waveguide block. Further, the waveguide block is configured so that an optical fiber can be connected to the other end face of the waveguide block which is orthogonal to the one end face.
