  • Patent number: 8344311
    Abstract: An optical touch panel comprises a transparent plate, a plurality of light-emitting devices and a plurality of light-receiving devices arranged around the transparent plate, a first substrate to which some of the light-receiving devices are fixed, and a second substrate to which others of the light-receiving devices are fixed. Each of the substrates has a surface layer that has a surface roughness which causes diffuse reflection of the same kind of light as light emitted by the light-emitting devices. A region having the surface roughness on a surface of the surface layer includes a region on the surface of the surface layer included in directivity ranges of the light-receiving devices fixed to the substrate.

  • Patent number: 8292520
    Abstract: A shield cover is provided with urging components that urge a light guide in the direction in which the light guide is inserted into a receptacle body to prevent the light guide from making contact with a light emitting element and a light receiving element when a receptacle body mates with a shield cover. Even if the light guide does not completely mate with the receptacle body, the urging components make contact with the light guide before the light guide makes contact with the light emitting element and the light receiving element so that an urging force by the urging components make the light guide completely mate with the receptacle body.

The first multiplier multiplies one of the resolver detection signals sin ? sin(?t+??) by the sine value sin ? of the digital output angle ? obtained from the angle calculation section. The second multiplier multiplies the other resolver detection signal cos ? sin(?t+??) by the cosine value cos ? of the digital output angle ? obtained from the angle calculation section. The adder adds the output of the first multiplier and the output of the second multiplier to output the sum signal sin(?t+??) as the reference signal.
