Communication apparatus for interfacing between wired and wireless voice / data generating / receiving apparatuses and a physical telephone line of a communication network that comprises a telephone outlet, which is mounted within a wall of a building and includes first and second connecting means. These connecting means are electrically connected to each other and to the physical telephone line. The second connecting means allow connecting a wired telephone apparatus to the telephone line. A detachable module is designed to be completely embedded within the telephone outlet, whenever inserted into the outlet, mechanically fits into, and electrically adapted to cooperate with the outlet. The module has a wireless end and first and second wired ends, and provides wireless coupling between the voice / data generating / receiving apparatus and the telephone line by utilizing the wireless end and wired coupling between the module to the telephone line, which is obtained by utilizing the first wired end and the first connection means. The module comprises all the circuit components required for receiving and transmitting the wireless voice / digital information and, if required, to transform the format of the received voice / digital information into a format complying with a communication protocol suitable to be fed to the communication network. The first wired end of the module comprises electrical contacts for providing the circuit components power, which exists on the telephone line, and signal connectivity, and is capable of mating with the first connection means. The second wired end of the module is designed to be completely embedded within the module, and intermediates between a wired telephone apparatus and the telephone line.

A method and apparatus for taking a sample from a flowing suspension formed by polymer particles and hydrocarbon diluent in a olefin polymerization process including at least one filter situated at a plane of an inside surface of a transfer conduit between reactors. Each filter includes perforations or pores having a size to prevent substantially any of the catalyst used in the polymerization process from passing through the filter, e.g., smaller than the smallest particle size of a catalyst used in the polymerization process. The pore or perforation size of each filter is preferably 0.1-10 .mu.m, preferably between 0.2-1 .mu.m. A pressure difference permits at least partial vaporization of the sample as it passes through the filter.

The embodiment of the invention provides an alliance block chain system based on a Kubernetes platform. By deploying bottom layer service of an alliance block chain in container carriers of a Kubernetes cluster, an alliance block chain system container is mirrored, and accordingly, horizontal expansion and plug-pull of a program module can be achieved conveniently through the dispatching and management functions of Kubernetes to a containerized application module. Thus, the flexibility of deploy and maintenance of the alliance block chain system are improved, and the alliance block chain system can support business systems with different demands conveniently.

The invention discloses a head-mounted device. The head-mounted device comprises a virtual reality helmet (1), a control portion (2), a transmission wire (4) and a headband portion. The virtual reality helmet (1) comprises a face shield attached to a face and a display screen disposed at the front end of the face shield; the control portion (2) is integrally connected with the virtual reality helmet (1) through the transmission wire (4), for controlling operation of the head-mounted device; and the headband portion is used for putting the virtual reality helmet (1) on the head portion of a user. According to the invention, through arrangement of the control portion connected with the virtual reality helmet, the head-mounted device does not need external connection with any other devices, and thus the portability and the compatibility are improved; through arrangement of a microphone and a shooting module, the man-machine interaction capability of the head-mounted device is enhanced; and through arrangement of an earphone seat on the transmission wire and arrangement of an detachable and adjustable rotation headband and an adjustment headband, user experience is improved.

Systems and methods for a test harness that are provided that allow for effective control over both the data records and the test methods that are used in a software test run. Data records and / or test methods can be associated with a priority, such that a level of priority may be selected for a particular test run, and substantially only data records and test methods of the selected priority are used in the test. The invention may be implemented as a data driven test pattern class library. The data driven test pattern class library may generate concrete prioritized test cases dynamically using code document object model (code DOM) for substantially each data record by using a class decorated with known custom attributes. The invention can be used to help testers implement data driven tests effectively and in an easily maintainable fashion with minimal code.

The invention discloses an emission microscope chip failure analyzing method. The method comprises the following steps of: developing chip test stimulus by utilizing a hardware description language; simulating the chip test stimulus by software, burning the chip test stimulus into an FPGA (Field Programmable Gate Array) substrate after the simulation becomes normal; outputting a plurality of stimulus pattern outputs to a plurality of pins of a chip to be analyzed by the FPGA substrate to ensure that the circuit of the chip to be analyzed enters a failure stimulus mode; and capturing a light-spot through the emission microscope, and performing circuit analysis and failure analysis on the light-spot. The invention also discloses an emission microscope chip failure analyzing system. By adopting the emission microscope chip failure analyzing method and system, multi-channel complex test vector application can be realized, a defect of the emission microscope chip can be positioned, the cost for chip failure analysis can be reduced, and the analyzing efficiency can be improved.
