摘要:
An electronic device is disclosed for controlling a high-voltage power source with multiple low-voltage switches. The electronic device includes a low-voltage DC power supply that allows for low-voltage wiring and components to be used to control the high-voltage power source using multiple low-voltage switches. The electronic device includes a single pulse generator that generates a pulse signal upon activation of any one of the multiple switches. The pulse signal activates a bistable circuit controller that is coupled the a high-voltage electronic switch to control high-voltage power to the load.

A method and system for managing semantic and syntactic metadata. Heterogeneous data is received. After the heterogeneous data is received, the semantic metadata associated with the received heterogeneous data is captured and syntactic metadata associated with the received heterogeneous data is captured. The semantic metadata describes contextually relevant or domain-specific information about data based on an industry-specific or enterprise-specific metadata model or ontology. The syntactic metadata included grammatical rules and structural patterns governing an ordered use of formats and arrangement pertaining to specified data. The received heterogeneous data and said captured semantic metadata and said syntactic metadata are logically linked. The heterogeneous data is stored in a repository.

A system and method for accurately positioning a computer position, and identifying the specific rack position where the computer is without manual intervention. A camera is installed on the computer to read the contents of a tag on the rack, so as to identify the position information of the computer. Specifically, the computer is provided with a self-positioning function, wherein: a camera is installed on the computer, and the camera is configured to read the contents of a tag attached on a side of a rack to house the computer to identify the rack position where the computer is.

A holding member and system including a first holding member and a second holding member, wherein each of the first holding member and the second holding member are coupled to opposite sides of a load plate of a socket. A holding member includes a body including a pair of arms extending from a first side of the body and spaced to accommodate a portion of an integrated circuit chip package therebetween and at least one clip extending from a second side opposite the first side. Also, a method including coupling an integrated circuit chip package to a first holding member and a second holding member, wherein the first holding member is coupled to a first side of a load plate of a socket and the second holding member is coupled to a second side of the load plate; and inserting the package into a socket of a printed circuit board.

Disclosed is a normal-incidence broadband spectroscopic polarimeter containing reference beam, comprising a light source, a first reflecting unit, a first concentrating unit, a second concentrating unit, a polarizer, a first curved mirror, a first planar mirror, a second reflecting unit and a probing unit. Also disclosed is an optical measurement system, comprising the normal-incidence broadband spectroscopic polarimeter containing reference beam. The normal-incidence broadband spectroscopic polarimeter containing reference beam achieves an integral combination of the light beams after splitting, can maintain the polarization state of the light beams while increasing the light transmission efficiency, and has a low complexity.
摘要:
A system is described for providing a virtual environment corresponding to a scene from nature. The virtual environment can be used to present performance metrics to a user. In some examples, the virtual environment can be a pond where performance metrics are represented using lily pads. The visual appearance of the lily pad can be dependent on metadata of the corresponding performance metric and the lily pads can be grouped according to how the performance metrics are grouped in the database
