Patent number: 12047665Abstract: An inspection device includes a small shutter in an opening of an inspection chamber, and a large shutter behind the small shutter. The small shutter has a closed state, an inward-open state, and an outward-open state. The small shutter in the inward-open or outward-open state is pushed by a workpiece and pivots inward in or outward from the inspection chamber. The large shutter has a light-shielding state, a driven state, and a stationary state. The large shutter in the light-shielding state overlaps the small shutter in the closed state and closes a clearance between the opening and the small shutter. The large shutter in the driven state is pushed by the small shutter in the inward-open state and pivots with the small shutter. The large shutter in the stationary state is separate from the small shutter in the outward-open state and at a same position as in the light-shielding state.Type: GrantFiled: November 24, 2022Date of Patent: July 23, 2024Assignees: NIDEC COPAL CORPORATION, FUJIFILM CORPORATIONInventors: Sena Amemiya, Masaki Takamatsu, Jumpei Shiraishi, Kyohei Shibuya

Patent number: 12047590Abstract: A video encoder receives a minimum number of bits (MIN) and a maximum number of bits (MAX) to be used to encode a segment of a sequence of image frames, the segment including a set of pictures contained in the sequence of image frames. The video encoder encodes the set of pictures using a total number of bits greater than the minimum number of bits (MIN), and not exceeding the maximum number of bits (MAX). Thus, the transmission bit-rate of the video encoder can be constrained to lie within a maximum and minimum rate. In an embodiment, the constraints are enforced over relatively short time intervals.Type: GrantFiled: August 22, 2022Date of Patent: July 23, 2024Assignee: Texas Instruments IncorporatedInventors: Soyeb Nagori, Naveen Srinivasamurthy, Anurag Jain
