    摘要: Provided are a light guide element and an image display apparatus capable of suppressing the occurrence of multiple images. The light guide element includes a light guide plate and a first incidence diffraction element, a second incidence diffraction element, a first emission diffraction element, and a second emission diffraction element that are provided on the light guide plate, in which the first and second incidence diffraction elements diffract incident light in different directions to be incident into the light guide plate, the first emission diffraction element emits light that is diffracted by the first incidence diffraction element and propagates in the light guide plate, the second emission diffraction element emits light that is diffracted by the second incidence diffraction element and propagates in the light guide plate, a period of a diffraction structure of the first incidence diffraction element and a period of a diffraction structure of the second incidence diffraction element are different from each other, a period of a diffraction structure of the first emission diffraction element and a period of a diffraction structure of the second emission diffraction element are different from each other, the first and second emission diffraction elements are disposed at a position where the first and second emission diffraction elements overlap each other in a plane direction of a main surface of the light guide plate, and a periodic direction of the diffraction structure of the first emission diffraction element and a periodic direction of the diffraction structure of the second emission diffraction element intersect with each other.

    摘要: A base unit and a modular centrifugal separator are disclosed. The base unit includes a stationary frame, a rotatable member, and a drive unit. The rotatable member delimits an inner space being configured for receiving at least one part of an exchangeable separation insert therein. The rotatable member is provided with a first opening at a first axial end configured for a first fluid connection of the exchangeable separation insert to extend through the first opening. The rotatable member includes a second opening at a second axial end configured for a second fluid connection of the exchangeable separation insert to extend through the second opening.

    摘要: An electronic identification band can be tightly attached to and surrounded around operating room instruments of various types or specifications for wireless identification by appropriately trimming the length thereof and then peeling off a release paper. The electronic identification band includes a protective housing directly formed on a mounting portion of an elongated flexible substrate to encase an RFID unit therein, such that the RFID unit can be isolated from an ambient environment by a simple structure, thereby achieving the protective function and thus significantly enhancing the economic efficiency in manufacturing the electronic identification band.

    摘要: The invention relates to an apparatus and a method for generating a Low-Density Parity-Check (LDPC) code. The apparatus includes: a LDPC encoder, a look-ahead circuitry and an exclusive-OR (XOR) calculation circuitry. The LDPC encoder is arranged operably to encode a front part of a user data using a 2-stage encoding algorithm with a parity check matrix to generate a first calculation result. The look-ahead circuitry is arranged operably to perform a dot product operation on a rear part of the user data and one of a plurality of feature rows corresponding to the parity check matrix to generate a second calculation result in each iteration. The XOR calculation circuitry is arranged operably to perform an XOR operation on the first calculation result and the second calculation result to generate a front part of the LDPC code.
