Abstract: A method for in-situ calibration of a fixed radiation dose rate instrument is provided, comprising: in a reference radiation field, calibrating a standard device, a first device to be calibrated to an nth device to be calibrated under a proposed database type, and obtaining a response signal of a first nonhomogeneous extended field generated by a first radiation source, and then establishing a database about type-relative position relationship-statistical data; generating a second nonhomogeneous extended field by a second radiation source with the same type as the first radiation source during in-situ calibration; and searching the type of a current device to be calibrated, and obtaining a final in-situ calibration factor of the current device to be calibrated according to a value in the database corresponding to the type.

Abstract: Provided is a gamepad with detachable handgrip which is related to the technical field of electronic products. The gamepad includes a holder and a left handgrip and a right handgrip that are respectively provided on left and right sides of the holder. The left handgrip and/or the right handgrip is detachably connected with the holder. By changing the fixed connection between the handgrip and the holder in traditional mobile phone gamepads and providing a detachable connection between at least one handgrip and the holder, users can replace the detachable handgrip with handgrips having different functions according to their own requirements. This helps to reduce the cost for users to buy gamepads and increases the flexibility of use of gamepads.

Abstract: The present application relates to a clamping type game operating handle. The clamping type game operating handle comprises a left handgrip, a right handgrip and a bearing balance seat, the right handgrip and the left handgrip are mutually complementary in structure; and the left handgrip (10) utilizing the front tension spring (40) and the right handgrip (20) utilizing the back tension spring (50) perform telescopic movement in the left-right direction corresponding to the bearing balance seat (30). According to the clamping type game operating handle, a user can stably fix an electronic device by gripping the handgrips, thereby preventing palms or fingers from excessively occupying a limited screen space of the electronic device, not only ensuring the experience effect of a game, but also fully releasing the palms or the fingers.
