A manual slope-adjusting mechanism for an elliptical cross trainer having a front sleeve with side tubes at both sides of the bottom of the front end of the elliptical cross trainer. According to a main characteristic of the invention, a thermoplastic layer and a top layer of synthetic paper are laminated on the antenna support so that the antenna and the chip are trapped in the thermoplastic and the three layers cannot be separated and so that the device is resistant to water and humid environments. The gate driver outputs the gate signals to the gate signal lines in an aligned order of gate signal lines in a second direction when the frame frequency is F1, and the gate driver outputs the gate signals to the gate signal lines in different order from the array order when the frame frequency is F2. The administration server is in communication with the resource registry and provides controlled access to the resource records. The invention also comprises such a device.
