Abstract: A projection apparatus including a projection device, a reflecting component, and an image capturing device is provided. The projection device is adapted to project an image light beam to form a projection image. The reflecting component is disposed on the projection device and has a reflecting surface. The image capturing device is disposed on the projection device and has an image capturing end. The image capturing end faces the reflecting surface. The reflecting surface is adapted to reflect the projection image to the image capturing end.

Abstract: A sensor package includes a substrate, a light sensor disposed on the substrate, at least one optical filter disposed on the light sensor, and an optical functional layer that is light-permeable, is disposed on the substrate, covers the light sensor and the optical filter, and includes multiple light-scattering particles. The light sensor has a light receiving region, and receives light through the light receiving region. The optical filter covers the light receiving region. When the light passes through the optical filter within an incident angle range and is received by the light receiving region, the light sensor responds to a wavelength range of the light, and a response spectrum is obtained. Within the incident angle range, an absolute value of an offset measured at a crest of a waveform of the response spectrum is less than or equal to 10 nm. An electronic device is also provided.

Abstract: An antimicrobial peptide, the peptide comprising 2 to 20 variable domains, each variable domain is a sequence of 2 to 20 consecutive basic amino acids, wherein (a) the variable domains are separated from each other by a variable linker, (b) the variable linker can have 1 to 20 any amino acids other than two or more consecutive basic amino acids, and (c) the peptide has no more than 100 amino acids.

Abstract: A pharmaceutical composition comprising: (a) an isolated peptide, wherein the peptide includes three or four arginine-rich domains (ARDs) from the carboxy-terminal region of hepatitis B virus core protein (HBc) and exhibits an anti-microbial activity; and (b) a pharmaceutically acceptable carrier.
