Abstract:
A cylindrical contact-type microphone relates to the technical field of audio devices, and solves the technical problem of inconvenient assembly of an existing contact-type microphone. The microphone comprises a shell, and a circuit board (4), a piezoelectric ceramic sheet (2), a lower-stage connection plate (3) and a conductive polar ring (5) which are mounted within the shell, wherein the shell is a two-section cylindrical conductive cylinder body, and a negative signal lower connection sheet of the lower-stage connection plate (3) is electrically connected to a step (13) at a joint portion of an upper cylinder section (11) and a lower cylinder section (12) of the shell.
Abstract:
A constructing method for a concrete cylinder of a construction steel bar of a high-rise steel structure adopts a constructing method of supporting inside and climbing outside. The outside of the cylinder adopts hydraulic mutual-climbing adhesive lifting scaffold creeping formwork system (100), and also has an outside wallboard mechanical formwork erection function and an outer frame protection function. For the inside of the cylinder, except that an appropriate structure is left for later processing according to a schedule requirement, beam walls all adopt a steel cylinder support to perform formwork erection, so as to greatly reduce the workload of repeatedly mounting/dismantling the scaffold and the formwork at a high place. The scaffold itself carries the formwork erection system, so formwork erection and formwork removal can be mechanized, thereby reducing the risk of formwork erection and formwork removal at a high place

Abstract:
A method and devices for restoring at least one setting are provided, the client device receives a code generated by a management device based on a time value and a parameter value that uniquely identifies the client device; the client device determines whether the code is valid; and if the code is valid the client device restores the at least one setting of the client device. It provides a convenient way to restore at least one setting of a client device.
Abstract:
This disclosure provides methods and servers to transmit data packets via Transmission Control Protocol (TCP) connections. In some aspects, transmitting data packets includes receiving a data packet from a first application on a first server. The data packet is analyzed to determine a destination address associated with a second server. The data packet is transmitted based on the address associated with the second server.
