  • Patent number: 9340128
    Abstract: In the left and right sides of the bezel, guide grooves are made, extending straight in the front-back direction. The cap has hinge pins, which are fitted in the guide grooves and which can slide along the guide grooves. Control pins protrude inward from the left and right sides of the bezel, and may abut on the back of the cap covering the opening of the bezel. If the cap is pushed, sliding the hinge pins along the guide grooves, the back of the cap slides on the control pins, and the cap swings around the hinge pins. As a result, the cap jumps up and is stored into the bezel.

  • Patent number: 9330660
    Abstract: A method and apparatus are provided for automatically acquiring grammar fragments for recognizing and understanding fluently spoken language. Grammar fragments representing a set of syntactically and semantically similar phrases may be generated using three probability distributions: of succeeding words, of preceding words, and of associated call-types. The similarity between phrases may be measured by applying Kullback-Leibler distance to these tree probability distributions. Phrases being close in all three distances may be clustered into a grammar fragment.

  • Patent number: 8937239
    Abstract: Provided are a light emitting control device, computer readable memory device, and method to control a light emitter associated with a pad capable of being struck to produce a sound. In response to detecting a striking of the pad, a tone associated with the pad is produced. A level of the tone produced is determined and a level meter brightness is determined based on the determined level of the tone. An output brightness for the light emitter is calculated associated with the struck pad using the determined level meter brightness and a brightness change pattern. The light emitter associated with the pad is controlled according to the determined output brightness.
