Abstract: A portable electronic device including a first body, a second body, a stand, and a hinge structure is provided. The stand has a first pivot part and a second pivot part opposite to the first pivot part, wherein the first pivot part is pivotally connected to the first body, and the second body is pivotally connected to the second pivot part. The hinge structure includes a first bracket secured to the second body, a second bracket secured to the second pivot part of the stand, a first movable base, a first shaft secured to the first bracket and pivoted to the first movable base, a second movable base, a second shaft secured to the first movable base and pivoted to the second movable base, and a sliding shaft fixed to the second movable base and slidably connected to the second bracket.

Abstract: In a non-invasive human metabolic condition measuring apparatus and method, a micro-light source emits an incident light having a wavelength from 329 nm to 473 nm to trigger a mitochondrial metabolite of a human mucosa tissue, and the metabolite is excited to generate a fluorescent signal having a wavelength from 405 nm to 572 nm, and the fluorescent signal is filtered by an optical filter, received by a micro receiver, and amplified by an amplification circuit sequentially, and then a filter circuit and an analog/digital conversion circuit of a microprocessing unit are provided for filtering and performing an analog/digital signal conversion respectively, so that the metabolite content can be calculated by the computation to provide human metabolic conditions, and a combination of micro components and circuits is used for miniaturizing the apparatus to provide a convenient carry of the apparatus.

Abstract: A method of manufacturing a semiconductor structure is disclosed, which includes providing a substrate comprising a bottom surface and a growth surface opposite to the bottom surface; forming a buffer layer comprising a first surface which is not a C-plane substantially parallel with the bottom surface on the growth surface; forming a semiconductor structure on the buffer layer; forming at least one cavity in the buffer layer; extending the cavity along a main extending direction; separating the substrate and the semiconductor structure; wherein the main extending direction is substantially not parallel with the normal direction of the first surface.
