A urinary catheter kit is provided. The catheter kit includes a catheter with a flared end and a package provided with interior protrusions for cooperating with the flared end of the catheter. The largest outer diameter of the flared end of the catheter is slightly larger than the smallest diameter of the package at the protrusions. Thereby, the protrusions will function as a backstop for the catheter. The rigidity of the catheter at the flared end is selected so that—depending on the angle of the flared end—the flared end will be able to flip over if it is subjected to a force over a predetermined level. Thereby the catheter will be able to be entered back into the package.

A liquid sensor may comprise a first electrode, a second electrode disposed inside the first electrode, and a partition wall comprising a surface defining a storage space with a first opposing surface of the first electrode and a second opposing surface of the second electrode. One of the first electrode, the second electrode and the partition wall may comprise a first communication opening communicating an inside of the storage space and an outside of the storage space and disposed at an upper portion of the storage space. One of the first electrode, the second electrode and the partition wall may comprise a second communication opening communicating the inside of the storage space and the outside of the storage space and disposed lower than the first communication opening. An opening direction of the first communication opening may be different from an opening direction of the second communication opening.

The invention discloses a method for generating a computational hologram of a three-dimensional point cloud model, comprising: (1) reading the original three-dimensional coordinate data of each object point in the three-dimensional point cloud model, and numbering each object point; The Z coordinate of an object point is added with a predetermined hologram recording distance; (3) the Z coordinates of each object point are used as the main cycle condition, and a two-dimensional blank surface is established for each cycle; (4) all object points are traversed, and the The object points whose Z coordinates are equal to the Z coordinates of the object point of the current cycle are found one by one, and correspondingly mapped to the two-dimensional blank surface to generate a two-dimensional surface containing point cloud model information; (5) the two-dimensional surface The method based on FFT is used to calculate the corresponding light field on the holographic plane; (6) Repeat (3)-(5) to superimpose the light fields obtained in each cycle to obtain a calculated hologram. The application of the invention can reduce the amount of calculation for calculating the hologram, and avoid the large amount of time consumed by the point source method and the extra storage space brought by the look-up table.

The invention relates to a method and a system for extracting, looking up and comparing visual patterns based on frame-to-frame variation characteristics. The method comprises the following steps: performing effective video preprocessing, and unifying various videos with different qualities and resolution ratios to a level with accordant resolution ratios and video qualities as much as possible; performing calculation of relativity between a number of adjacent frames to find out a plurality of image blocks with obvious (such as the biggest difference) characteristics between a number of the adjacent frames, and coding the plurality of the blocks to form frame fingerprints; and combining the sequences of the frame fingerprint to form the visual patterns. Simultaneously, because the method for extracting the visual patterns has good robustness, a visual pattern comparison and lookup algorithm which is matched with the method for extracting the visual patterns and is based on matched inverted row query and window sliding is invented. Under the condition of ensuring the accuracy of the query, the retrieval rate is greatly improved. The method and the system can be applicable for real-time operations.
