Abstract: An object is to provide an electronic device capable of recognizing a user's facial feature accurately. A glasses-type electronic device includes a first optical component, a second optical component, a frame, an imaging device, a feature extraction unit, and an emotion estimation unit. The frame is in contact with a side surface of the first optical component and a side surface of the second optical component. The imaging device is in contact with the frame and has a function of detecting part of a user's face. The feature extraction unit has a function of extracting a feature of the user's face from the detected part of the user's face. The emotion estimation unit has a function of estimating information on the user from the extracted feature.

Abstract: To provide a measuring apparatus 1 and a system 100 for constructing a three-dimensional model which are compact and are capable of obtaining data in a wide range while preventing the cameras and scanners from entering the data. The measuring apparatus 1 and the system 100 include an inertia measuring unit 30, an omnidirectional camera 10 for photographing scenery of an upward direction and a sideward direction, and a scanner 20 for scanning scenery over 360 degrees in a circumferential direction, wherein the omnidirectional camera 10 is disposed above the inertia measuring unit 30 and the scanner 20 is disposed in an upward and sideward direction of the omnidirectional camera 10.

Abstract: A mixed acid anhydride consisting of higher fatty acid having 6 to 22 carbon atoms and sulfuric anhydride is reacted with amino acids, peptides or proteins in the presence of a base to form N-higher aliphatic acyl derivatives of amino acids, peptides or proteins respectively in good yield. The reaction mixture comprises N-acylated-amino acids, peptides or -proteins and sulfate salts and may be directly used as detergent.
