  • Patent number: 10386955
    Abstract: A liquid crystal display device includes a panel unit and a driving unit driving the panel unit. The driving unit includes as operation modes a first mode in which a detection operation of a first external object is performed in units of a divided region obtained by dividing an entire surface of a touch region of the panel unit and a second mode in which a detection operation of a second external object is performed on the entire surface of the touch region of the panel unit. The first mode is a mode detecting, in units of the divided region of the panel unit, a contact position of the first external object with each divided region, and the second mode is a mode detecting, on the entire surface of the panel unit, whether or not the second external object approaches the entire surface.

  • Publication number: 20190041393
    Abstract: Based on an endogenous peptide whose peptide sequence is known among endogenous peptides produced in vivo and on a full-length sequence of a precursor protein of the endogenous peptide, a database creation unit 11 generates a peptide sequence as a target peptide sequence, the peptide sequence containing one or more residues of a partial sequence of the endogenous peptide, thereby creating a target peptide sequence database 111 including a plurality of the target peptide sequences. The mass spectrometry unit 12 performs mass spectrometry on a peptide sample. A peptide assignment unit 14 determines a peptide sequence of an endogenous peptide contained in the peptide sample based on the plurality of target peptide sequences generated by the database creation unit 11 and on a mass spectrum obtained by the mass spectrometry unit 12.
