A three-dimensional data point encoding method, decoding method, and encoding device. The encoding method includes: determining maximum values of side lengths of a cuboid of three-dimensional data points to be encoded in three directions according to position coordinates of the three-dimensional data points to be encoded; performing at least one octree partition process on the cuboid, to obtain a plurality of first-type sub-blocks; performing at least one quadtree partition process or binary tree partition process on at least one first-type sub-block of the plurality of first-type sub-blocks; and encoding the three-dimensional data points to be encoded according to partition results of the cuboid.

Three-dimensional data point encoding and decoding method and device

A method for determining an altitude of a moving object includes obtaining pressure-dependent data from a plurality of sensors and computing the altitude of the moving object based on the pressure-dependent data from the plurality of sensors. Each of the sensors is mounted on the moving object with a respective primary orientation direction, and the primary orientation directions of at least two of the sensors are different.

A blower includes a housing, and an impeller and a motor received in the housing. The motor drives the impeller to rotate. The motor includes a stator and a rotor. The stator includes a stator core and windings wound around the stator core. The stator core includes a yoke and teeth extending from the yoke. A distal end of each of the teeth forms a tooth tip, with a slot opening formed between each two adjacent tooth tips. The rotor includes a permanent magnet forming a plurality of magnetic poles. The stator and the rotor define an air gap therebetween. A circumferential width of the slot opening is equal to or less than two times of a radial width of the air gap.

A two-dimensional barcode includes a plurality of macro modules arranged in a two-dimensional array in a spiral sequence, each of macro modules includes a predetermined number of data unit modules for storing data codewords of a predetermined binary stream of bits, a predetermined number of cluster unit modules for storing a predetermined cluster number representing a location of the macro module, and a predetermined number of rim unit modules which possess a predetermined color to form a rim of the macro module. The rim unit modules of two adjacent macro modules are contrasting with each other to enhance identification of the respective macro module.

2D coding and decoding barcode and its method thereof

The present invention relates to a scanning device with a positioning senor and a processing method to obtain images, comprising a casing, linear contact image sensor (CIS), further comprising a system processor Pfor controlling the work of said CIS by timing signal, the optical coordinate sensors and the displacement processor Pand Pfor estimating the coordinate increment () and the coordinate increment () of the real-time displacement, an A/D circuit and data buffer; said system processor Ppackets original scanning data with positioning information (), and then transfers to the upper machine. An image processing module in the upper machine de-packets said original scanning date (); Converts out the coordinate of the terminal pixel of said linear contact image sensor (CIS), and configures the image line in the object image configuring area; and calculates and rectifies the relative offset of the positioning coordinate of the two scanning bands making using of the statistical characteristic of part of pixel data in the overlapped area of the two scanning bands.

Scanning device with a positioning sensor and a corresponding processing method to obtain images

An insert-type barcode reader has a body support with an insertion slot for receiving a card with barcode. A circuit board and a CIS component module electrically connected to the circuit board with each mounted to the body support to scan and process signals. A roller is mounted to the body support for movement relative to the CIS component module to allow the card to be properly guided into the insertion slot and tightly pressed onto the CIS component for accurate scanning of the barcode on the card. Two photoelectric sensors mounted to the body support are electrically connected to the circuit board for sensing the card entering and leaving the insertion slot to control starting, running and stopping of the scanning function of the CIS component module.
