This application provides a radio frequency (RF) front-end module, relating to the field of RF technology. The RF front-end module includes a power amplification module, a signal coupling module, and a detection module. The signal coupling module includes a control unit and a bidirectional coupling circuit, which is connected between the power amplification module and the detection module. The control unit is configured to control the bidirectional coupling circuit to be in a conducting state. The bidirectional coupling circuit is configured to couple the RF signal on the signal transmission line of the power amplification module to the detection module. The detection module is configured to detect a pre-distortion signal based on the coupled signal transmitted by the bidirectional coupling circuit. This application achieves bidirectional coupling by coupling the transmitted and echo signals on the signal transmission line of the power amplification module to the detection module, thereby enabling accurate detection and feedback of the nonlinear characteristics of the power amplification module's core. Based on this, the pre-distortion signal determined is more accurate.

The invention provides a gas detection sound-light alarm device and an alarm state identification method, and relates to the technical field of industrial gas detection.The device comprises a detector host module, a safety barrier module and a sensor sensing component which are arranged in a detector explosion-proof cavity, and a sound-light alarm module assembled outside the detector explosion-proof cavity; the detector host module is electrically connected with the sensor sensing part and the safety barrier module, and the safety barrier module is electrically connected with the sound-light alarm module through a two-wire system. And when the detected gas concentration information reaches a preset alarm threshold value, or the sensor sensing part has a fault and the detection is out of range, the detector host module synchronously realizes power supply on-off and parameter configuration signal transmission to the sound-light alarm module through the safety barrier module. The device has the advantages of low wiring and intrinsic safety cost, compact size, safe and reliable driving scheme and the like, can be widely applied to gas detector alarm devices, and guarantees the safety of personnel life and production equipment.

This application discloses a multi-functional outdoor fan, comprising: a body and two heads of different specifications, one of which is installed on the body; each head includes: a head shell and a head connector, the head connector partially protruding from the bottom of the head shell, and an upper conductive component; the body includes: a body shell, a lithium battery, a body connector, and a lower conductive component; the body and head are slidably assembled via the body connector and head connector, and the upper and lower conductive components are electrically connected after assembly. This utility model allows for the installation of either a fan head or a lamp head on the body, depending on usage requirements; with the fan installed, it functions as a handheld fan, and with the lamp head installed, it functions as a flashlight, offering multiple functions; a display screen is provided on the front cover of the fan head, making it easier for the user to observe the displayed content when holding the body and aligning the air outlet with the user.

This utility model discloses a bottled medicine inspection machine, belonging to the field of light inspection machines. It includes a power base, an arranging body, an assembly frame, and light inspection equipment. The arranging body includes a bottle-holding ring, an arranging disc, a drive shaft, a lifting linkage, a first telescopic rod, a rotating disc, a second telescopic rod, a transmission assembly ring, a lifting guide plate, gears, a limiting structure, a tooth groove, an elastic element, a sliding ball assembly seat, and a sliding ball. By providing a rotating disc on the bottle-holding ring that rotates with the arranging disc, the bottled medicine is also driven to rotate by the rotating disc during inspection. At the same time, the rotation of the bottle-holding ring also drives the lifting linkage to rotate synchronously. The rotation of the lifting linkage drives the bottle-holding ring to rise and fall with the concave and convex structure of the lifting guide plate, thereby causing the bottled medicine on the bottle-holding ring to rise and fall as well. This allows for the inspection of all sides of bottled medicines at different heights, increasing the accuracy of the inspection. Moreover, the rotation and lifting do not require additional power or wiring, reducing the inconvenience of wiring and subsequent maintenance.

This utility model discloses a wireless hysteroscope with a screen, including a handle, a circuit board, an insertion part, a wireless display screen, and a wireless module. The wireless module is electrically connected to the circuit board, which is mounted on the handle. The insertion part is elongated, with its tail end mounted on the handle and its head end away from the handle. The wireless display screen is detachably mounted on the handle and is also wirelessly connected to the wireless module. Therefore, this wireless hysteroscope with a screen eliminates the need for cable connections, making it convenient to use and suitable for rapid examinations and treatments, including in outpatient settings. Furthermore, since the wireless display screen is detachably mounted on the handle, it is easy to detach and assemble. After use, the wireless display screen can be removed and reused, while the rest can be discarded.

This invention belongs to the field of fiber optic sensing and detection technology, and provides a method for detecting the strain field of an engine turbine disk based on a fiber optic grating sensor string and a high-speed smooth ring. The scheme includes an engine, fiber optic grating sensors, a high-speed smooth ring, a fiber optic grating signal demodulator, and a host computer.
