Abstract: A brush module for a rotary table includes: a housing, a brush unit, a first pushing unit and a second pushing unit, the brush unit includes a brush disposed in the housing, a conductive wire electrically connected to the brush, and a pushing force for pushing the brush towards the opening of the housing. The first and second pushing units oppositely provided on the housing provide the brush a first and a second pushing forces in opposite directions to resist the lateral thrust generated by friction between the brush and the rotary disk of the rotary table, thereby greatly reducing the vibration, shaking, slipping, line contact and other conditions of the brush caused by high-speed rotation of the rotary disk, avoiding damaging the peripheral surface of the rotary disk, and maintaining good electrical contact between the brush and the rotary disk.

Abstract: A system, an apparatus, and a method for cloud resource allocation are provided. The cloud resource allocation system includes a plurality of worker nodes and a master node. The master node includes: an orchestrator configured to: obtain multiple node resource information respectively reported by a plurality the worker nodes through a resource manager; and parse a job profile of a job request obtained from the waiting queue through the job scheduler and decide to execute a direct resource allocation or a preemptive indirect resource allocation for a job to be handled requested by the job request based on the node resource information and the job profile.

Abstract: A convolution operation module comprising a first memory element, a second memory element and a first operation unit is presented. The first memory element is configured to store a first part of a first row data of an array data. The second memory element is configured to store a second part of a second row data of an array data. Wherein the second row data is adjacent to the first row data in the array data and the first part and the second part have a same amount of data. The first operation unit is coupled to the first memory element and second memory element. Wherein the first operation unit integrates the first part and the second part into a first operation matrix. Wherein the first operation unit performs a convolution operation on the first operation matrix and a first kernel map to derive a first feature value.

Abstract: An ultrasonic sensing device includes a support body and an ultrasonic sensor. The support body includes an accommodating space, and a positioning space at a center of the accommodating space. The ultrasonic sensor includes a body portion in the positioning space, at least one sensing channel portion extending from the body portion and in the accommodating space, at least one piezoelectric unit at one end surface of the sensing channel portion, and a second channel passing through the body portion. An inner diameter of the positioning space is greater than an inner diameter of the accommodating space, and an outer diameter of the sensing channel portion is smaller than the inner diameter of the accommodating space. Thus, a gap is formed between the sensing channel portion and the accommodating space, and the piezoelectric unit is located outside the accommodating space to come into contact with an exterior.

Abstract: The present invention relates to a RC filtering device, consists of: a lower substrate, a first intermediate substrate, a second intermediate substrate and an upper substrate. On top surface of the lower substrate is a cross form electrode layer. At both ends of the electrode layer in one direction forms a pair of air gaps to function as over voltage protection. The first intermediate substrate is formed above the lower substrate also has a pair of grooves corresponding to said air gaps, and on the top surface of the second intermediate layer, there is a transmission wire. The said transmission wire is formed with metallic layer at its both ends and the metallic oxide layer made with electrical resistance, this transmission wire and the electrode layer on the lower substrate form an RC filtering device.

Abstract: A file management system is used in a peer-to-peer file-share mechanism. The file management system is used for managing at least one file transmitted between at least one data terminal and at least one abstracting terminal via networking. The data terminal stores the file and a searching data corresponding to the file. The searching data comprises a characteristic data of the file and a location of the file. After the characteristic data is chosen at the abstracting terminal, the abstracting terminal traces the location via networking, couples to the data terminal, and further abstracts the file corresponding to the characteristic data. The data terminal uses an encryption module to encrypt the file to an encryption file. A software package is used for conveniently transmitting the file to the abstracting terminal. Thus, the software package can decrypt the encryption file to the file for a user subsequently to use at the abstracting terminal.

Abstract: A file access controlling method applied to a network for controlling access of a file transferred via a predetermined transmission scheme. The file access controlling method includes obtaining characteristic data corresponding to the file, and comparing a look-up table with the characteristic data, wherein if the look-up table includes a record corresponding to the characteristic data, an access limitation is imposed on the file according to the record to control access of the files.

Abstract: A peer-to-peer digital copyright management method and system are disclosed. The invention uses a network with a peer-to-peer connection structure. Each workstation has equivalent abilities and responsibilities. This style is distinguished from the client/server structure, where some computers are assigned to service other computers. In general, the peer-to-peer network is simpler. It does not need to be equivalent to the strong execution abilities and bandwidths of the client/server network. However, it has the drawback of being hard to manage. The invention combines all advantages of the peer-to-peer network platform and the client/server structure. In addition to providing a search share system, which can peer-to-peer rapidly distribute digital contents, it further provides an effective copyright management system which strictly controls file sharing and downloads. Network service points or equivalent currencies for each shared file download are accurately obtained from the download user.
