  • Patent number: 10717447
    Abstract: The present invention includes: a visual perception target determination unit for determining a visual perception target by using a saliency model for determining that an object to be visually perceived at a glance is a visual perception target, a surprise model for determining that an object behaving abnormally is a visual perception target, and a normative model for determining that an object to be visually perceived by a viewing action of a driver serving as a norm is a visual perception target; and a visual guidance unit for determining whether or not an overlooked visual perception to which a line-of-sight direction detected by a line-of-sight detection unit is not directed is present, and guiding a line-of-sight of a driver toward the overlooked visual perception target, when the overlooked visual perception target is present.

  • Publication number: 20200225190
    Abstract: A collimated beam (23) of a surface acoustic wave propagates on a piezoelectric substrate (22) while passing through sensitive film (25) to adsorb a sensing gas. Signal processing unit (40) transmits an exciting burst signal to sensor electrode (24) to excite the collimated beam (23), receives first and second returned burst signals after the collimated beam (23) has propagated, and calculates a target gas parameter by a target leakage factor of the background gas and a relation between reference gas parameters and reference leakage factors of reference gases, the leakage factor is provided by first and second attenuations of the first and second returned burst signals, respectively, using waveform data of the first and second returned burst signals.

  • Publication number: 20190360966
    Abstract: System and method for measuring a gas concentration are provided. A ball sensor generates a collimated beam of a surface acoustic wave including fundamental wave of first frequency and harmonic wave of second frequency, which propagates through a orbital path on piezoelectric ball while passing through sensitive film to adsorb a target gas. Temperature control unit controls ball temperature of the ball sensor. Signal processing unit transmits a burst signal to sensor electrode of the ball sensor to excite the collimated beam, receives burst signals after the collimated beam has propagated a predetermined number of turns around the piezoelectric ball, and calculates the gas concentration and the ball temperature by first and second relative changes in delay times of the first and second frequencies, respectively, using waveform data of the burst signals.

  • Patent number: 8247578
    Abstract: The present invention provides a process for producing a 3-aralkyloxypyrrolidine derivative which is important for production of pharmaceutical products and the like. In the present invention, a N-protected-3-hydroxypyrrolidine is converted into a N-protected-3-aralkyloxypyrrolidine by allowing an aralkyl halide to act in the presence of a base and at least one of a metal halide and a phase-transfer catalyst followed by deprotecting a N-protecting group to convert it to a 3-aralkyloxypyrrolidine derivative and subsequently treating the derivative in a solvent containing a polar solvent, thereby obtaining the 3-aralkyloxypyrrolidine derivative as a crystal. According to the present invention, a 3-aralkyloxypyrrolidine derivative of high purity can be produced conveniently and efficiently on an industrial scale.

  • Patent number: 7473803
    Abstract: The invention provides processes for producing efficiently optically active 2-halogenocarboxylic acids useful in the preparation of drugs or the like and salts thereof with amines. Specifically, an optically active 2-halogenocarboxylic acid is produced by halogenating an optically active amino acid in water in the presence of a hydrophobic organic solvent and nitrous acid with the configuration retained and with the racemization inhibited through the removal of 2-hydroxy-bromocarboxylic acid formed as a by-product; the obtained optically active 2-halogenocarboxylic acid is transferred to an aqueous phase by converting it into a salt thereof with a base, followed by the removal of the organic phase; and the optically active 2-halogenocarboxylic acid is transferred again to an organic solvent phase, followed by the removal of the aqueous phase, whereby an optically active 2-halogenocarboxylic acid is obtained through the removal of a halogen component.
