2results about How to "Composite function" patented technology

This application relates to an integrated optical module that implements APR (Automatic Presence) function, comprising: two optical amplifier units connected by an optical fiber link; each optical amplifier unit includes: a first optical amplifier for transmitting signals and a second optical amplifier for receiving signals, and a control transmission module; the control transmission module is electrically connected to the first and second optical amplifiers, and is used to control the power of the first optical amplifier and monitor the operating status of the second optical amplifier; the control transmission module is connected to the optical fiber link via a WDM coupler; and an MCU control unit can control the OSC (Optical System Control) optical module to periodically transmit low-frequency signals or tuning signals to the optical fiber link, so that when one of the optical fiber paths is disconnected, the MCU control unit can control the optical amplifier unit at the other end to switch the OSC optical module from transmitting low-frequency signals to transmitting tuning signals and fiber LOS (Loss of State) signals, and control the first optical amplifier connected to itself to shut down, thus entering the APR process.

This invention discloses a gear cutting machine tool with a measuring tool function, relating to the field of gear cutting technology. The invention includes a cutting table, a gantry frame mounted on top of the cutting table, a laser cutting assembly installed on the inner top of the gantry frame, a lifting cylinder mounted on top of the gantry frame, and a cutting module fixedly mounted at the bottom of the telescopic end of the lifting cylinder. A bottom mold is fixedly mounted at the bottom of the mounting shaft, and several adjustable molds are provided on the top of the bottom mold. Both the bottom mold and the adjustable molds have cooling chambers located at the gear teeth. This invention adopts an integrated mold shielding and cooling design, which can prevent accidental cutting, provide a measuring tool for the gear, and, based on the high heat flow density at the tooth tip and root, set cooling channels in corresponding areas to achieve precise thermal management. It integrates cutting guidance and active cooling into the same mold, resulting in a compact structure and multifunctional design.
