Abstract: An internal-reflective telecentric lens system includes a first lens assembly, a reflector, and a second lens assembly. The first lens assembly includes a first lens. The second lens assembly includes a second lens, a third lens, and a fourth lens, that are disposed in sequence along a light path. The first lens assembly is configured to receive and output one or more light beams towards the reflector. The reflector is configured to reflect the light beams towards the second lens assembly. The second lens assembly is configured to receive and converge the light beams reflected by the reflector at a diaphragm between the second lens and the third lens, and transmit the light beams past the diaphragm through the third and the fourth lenses for imaging.

Abstract: This application provides a frame display method in a game application performed by a computer device. The method includes: receiving a frame message within a first cooldown period of a target skill; determining whether the first cooldown period ends, according to a remaining time of the first cooldown period and a frame interval time; determining a compensation time corresponding to the first cooldown period according to an actual time of the first cooldown period and a adjusted cooldown time of the target skill when the first cooldown period ends; and displaying a skill cooling image of the target skill in a next image frame, and entering a second cooldown period of the target skill. In this application, the number of frames overflowed previously is made up each time a skill is released, to ensure that the actual number of frames under acceleration/deceleration is close to the theoretical number of frames.

Abstract: A method for speech recognition based on language adaptivity comprises obtaining voice data of a user. The method also comprises extracting, based on the obtained voice data, a phoneme feature representing pronunciation phoneme information. The phoneme feature is input to a pre-trained language discrimination model that is pre-trained based on a multilingual corpus. A language discrimination result corresponding to the phoneme feature and in accordance with the language discrimination model is obtained. The method also comprises obtaining a speech recognition result of the voice data based on a language acoustic model of a language corresponding to the language discrimination result. The method further comprises determining a speech recognition result of the voice data based on a language acoustic model of a language corresponding to the language discrimination result.

Abstract: This application provides a positioning method performed at a computer device. The method includes: obtaining an image photographed by an image capturing apparatus disposed at a roadside and a photographing orientation of the image; determining pixel coordinates in the image for a target object in the image; determining a relationship between the pixel coordinates corresponding to the photographing orientation and location coordinates in a physical world; and determining location coordinates of the target object in the physical world according to the relationship and the pixel coordinates. According to this application, location information of an object can be accurately determined according to a correspondence between pixel coordinates in an image and location coordinates in a physical world, and a transform relationship between pixel coordinates in different photographing orientations, and avoiding the problem that the target object cannot be positioned due to a blind area in a view field.

Abstract: Disclosed is a microfluidic chip, including a chip upper cover, a chip lower layer, a membrane, a sealing gasket and a sealing ring. The microfluidic chip is provided with a sample storage zone, a droplet formation zone, a droplet storage zone, a droplet detection zone and a waste liquid storage zone. The sample storage zone, the droplet formation zone, the droplet storage zone, the droplet detection zone and the waste liquid storage zone communicate by means of a micropore or a micro-channel. The droplet formation zone is used to transform the sample phase into tens of thousands to millions of droplets, the droplets undergo the PCR reaction in the droplet storage zone, the droplet detection zone is used to perform optical detection on the droplets after PCR reaction, and the waste liquid storage zone is used to collect and store the detected droplets and continuous phase.

Abstract: The invention relates to a recommendation method for an internal service entity service entrance of a network platform. The method comprises the following steps of: S1, sending service keywords of each service entity as a word source of tokenizer to the tokenizer of a network platform; S2, sending a core corpus corresponding to each network content in the network platform to a tokenizer, wherein the core corpus is the core content of the network content; S3, carrying out word segmentation on that core corpus by the tokenizer, and matching with the service keywords after the word segmentation is completed; S4, if the participle of the core corpus is matched with the service keywords, setting a service entrance of the service entity corresponding to the matched service keywords in the network content corresponding to the core corpus.

Abstract: A cleaning module includes a box body, at least one driving mechanism, and at least one rotating plate assembly. The at least one driving mechanism is positioned on a bottom surface of the box body and includes at least one drive shaft. Each rotating plate assembly is connected to a corresponding drive shaft and includes a cleaning surface, and the cleaning surface is configured to rotate under the drive of the corresponding drive shaft to clean a to-be cleaned surface.
