The invention discloses a mobile terminal and an NFC antenna. The mobile terminal includes: a terminal body; an NFC antenna, the NFC antenna is arranged on the back of the terminal body, and the NFC antenna passes through the The longitudinal centerline and / or the transverse centerline, and the parts of the NFC antenna located on both sides of the longitudinal centerline and / or the transverse centerline on the back of the terminal body are asymmetrical. The mobile terminal according to the embodiment of the present invention has a small resonance frequency shift when performing P2P operations, and has the advantages of high communication sensitivity, high communication success rate, and strong communication capability.

The invention provides a backlight module and a display panel. The backlight module sequentially comprises an optical film group, a light guide plate, a reflection sheet and a bottom plate, and further comprises a frame connected to the bottom plate and arranged opposite to the side surface of the light guide plate, wherein a gap exists between one end of the optical film group and the frame. Thetechnical effect of the backlight module is that the gap is reserved on one side of the optical film group, so that the optical film group still remains flat at high temperature, high optical characteristics are kept, and the product competitiveness is improved.

The embodiment of the invention relates to the technical field of semiconductor lasers, and especially relates to a DLP (Digital Light Procession) projection system applying multiple semiconductor lasers. The DLP projection system is used for solving the problems of complicated structure and high cost due to the additional arrangement of a speckle eliminating device in the projection system in theprior art.

The invention provides a CT (current transducer) energy acquisition-based ultrasonic bird repelling device for a series compensation platform, and can effectively prevent and control the problem of bird trouble of a series capacitor compensation device. In the ultrasonic bird repelling device, a circuit energy acquisition CT is adopted to supply power, large current passing through a circuit is converted into a required current, the current passes through an isolated CT realize electrical isolation, the high frequency part of power frequency current is filtered by virtue of a low-pass filter, direct current voltage is rectified and output by virtue of a rectifier, a high-frequency signal generator generates a high-frequency voltage signal between 16 and 25kHz immediately, and the high-frequency voltage signal is loaded to a piezoelectric ceramic plate of an ultrasonic speaker and is amplified to generate a high-volume ultrasonic wave which is between 16 and 25kHz and has a sound pressure level not lower than 90dB by virtue of the speaker. According to the bird repelling device, the energy acquisition CT is used as a power supply to guarantee stable high-power output, so that all-weather 24-hour uninterrupted large-area bird repelling is guaranteed; and a mode that two ultrasonic speakers are connected in parallel is adopted, and ultrasonic wave with variable frequencies is alternately and continuously generated, so that birds cannot adapt to the ultrasonic wave, and the durability of bird repelling effect is guaranteed.

The invention relates to the technical field of floor drains, in particular to a through-type deodorization floor drain with a float. The through-type deodorization floor drain is used for solving the technical problem that in the prior art, the deodorization effect of an existing floor drain is bad. The through-type deodorization floor drain comprises a shell, a cover and the float; the end, facing the cover, of the shell is open, and a water outlet is formed in the end, far away from the cover, of the shell; the float is arranged in an inner cavity of the shell and separably connected to the water outlet of the shell in an abutting mode; the cover is arranged on the shell and provided with a water inlet communicated with the inner cavity of the shell; the middle of the shell is provided with a float channel for allowing the float to stretch out. The through-type deodorization floor drain with the float can effectively solve the technical problem that the deodorization effect of the floor drain is bad.

The invention discloses a protection device of a wireless indicator diagram sensor of a pumping unit and belongs to the field of oil extraction equipment. The protection device comprises a protection cylinder and a protection box, wherein the protection cylinder and the protection box are connected in sequence. The protection cylinder is used for containing the transmitting end of the wireless indicator diagram sensor, the protection box is used for containing the pressure bearing end of the wireless indicator diagram sensor, and a polish rod of the pumping unit is sleeved with the protection box. An activating hole and a transmitting hole are formed in the protection cylinder, and the activating hole corresponds to an activator of the wireless indicator diagram sensor in position, and the transmitting hole corresponds to a transmitter of the wireless indicator diagram sensor in position. An activating hole plug is arranged on the activating hole in a matched mode, a transmitting hole plug is arranged on the transmitting hole in a matched mode, and both the activating hole plug and the transmitting hole plug are made of insulating materials. According to the protection device of the wireless indicator diagram sensor of the pumping unit, the transmitting end and the pressure bearing end of the wireless indicator diagram sensor can be effectively protected, and normal work of the wireless indicator diagram sensor is guaranteed; and using is convenient, and large-scale application and popularization are facilitated.

The invention discloses an emergency escape rope ejection system for a public bus and aims at solving the problem that passengers in the existing public bus are easy to fall down to be injured duringjumping windows in case of an emergency. According to the key point of the technical scheme, the emergency escape rope ejection system for the public bus comprises an ejection device, a bearing assembly and a control circuit, wherein the ejection device is arranged on one side of a window and comprises a box body, a pull rope, a force bearing part, a force applying assembly, an opening and closingassembly and a rope outlet, wherein the force bearing part is fixed at the other end of the pull rope; the force applying assembly is arranged in the box body and used for ejecting the force bearingpart out of the box body; the opening and closing assembly is arranged in the box body and used for controlling the force applying assembly to apply an ejection force to the force bearing part when the window is broken; and the rope outlet is formed in the box body; the bearing assembly is arranged on the other side of the window and used for limiting the pull rope to cross over the window; and the control circuit is used for detecting the integrity of the window and controlling the opening and closing assembly to be opened when the window is broken so that the force applying assembly appliesthe ejection force to the force bearing part. The emergency escape rope ejection system for the public bus has the advantages that convenience is provided for the passengers to grab an escape rope, and falling and injuries are reduced.
