    Abstract: A point cloud encoding and decoding method, an encoder, and a decoder are provided. The encoder determines a processing order of point cloud data during point cloud encoding. The encoder determines a coordinate-axis-order index corresponding to the processing order. The encoder encodes the coordinate-axis-order index and signals encoded bits into a bitstream. The encoder processes the point cloud data according to the processing order, to obtain point cloud data to-be-encoded. The encoder encodes the point cloud data to-be-encoded and signals encoded bits into the bitstream. The decoder parses a bitstream to obtain a coordinate-axis-order index, determines a processing order of point cloud data during point cloud decoding according to the coordinate-axis-order index, parses the bitstream to obtain recovered data of the point cloud data, and determines a position of coordinate data of the point cloud data in a storage unit of the recovered data according to the processing order.

    Abstract: An Illumination device includes light emitting devices and an optical system for collimating light emitted by the light emitting devices. A first group of the light emitting devices are arranged in a first array having first gaps, and a first optical system is arranged near the first group of light emitting devices. At least one second group of the light emitting devices are arranged in a second array, and the second array has second gaps. The second optical system is arranged near the second group of light emitting devices. The first and second optical systems are arranged so that, in a distance from the illumination device, light emitted by the first group of light emitting devices, collimated by the first optical system, and light emitted by the second group of light emitting devices, collimated by the second optical system, are superimposed to form a gap-free illumination field.

    Abstract: Automatic fire protection sprinkler assemblies having a trigger assembly with a thermally responsive element and a yoke that seats and facilitates heat flow over the thermally responsive element. The yoke includes an elongate support member with a central region centered between two end portions with linear portions extending between the central region and the end portions. The yoke defines a heat impact region in which the end of the trigger assembly is received and seated. The yoke also provides a lateral access to define a fluid flow path in fluid communication with the heat impact region to facilitate heat flow over the thermally responsive element.

    Abstract: An immunogenic composition is provided herein. The immunogenic compositions are used to identify and select immunogenic antigens that elicit immune responses in a subject and may be subsequently used in multi-antigen vaccine compositions against one or more diseases or conditions. According to some embodiments, the immunogenic composition may include a plurality of nucleic acid fragments or minigenes derived from a nucleic acid library, wherein each nucleic acid fragment encodes a different antigen or functional portion thereof, and wherein the different antigens or functional portions thereof are associated with one or more disease or condition. The immunogenic composition may also include a delivery medium loaded with the plurality of nucleic acid fragments and in some embodiments, the delivery medium is loaded with nucleic acid fragments in such a way that individual antigen presenting cells receive only a subset of the nucleic acids within a vaccine in order to minimize antigenic competition.
