Abstract: An impact protection controller for an electric height-adjustable desk. The controller comprises an MCU, a motor drive circuit, a motor current sampling circuit, a current amplifier circuit, a Hall pulse generator, and a Hall filter. The MCU controls the motor drive circuit. A signal transmitted by the Hall pulse generator is sent to the MCU via the Hall filter. A motor current is sampled by the motor current sampling circuit, and the result is sent to the MCU via the current amplifier circuit to detect a change of the current. The controller further comprises a shock switch provided outside of and connected to the MCU, or provided inside of the MCU. The present invention combines current detection and shock detection to improve sensitivity and reliability of impact protection.

Abstract: A touch controller having a display screen comprising a display screen, a touch integrated module, a control circuit and a housing. The display screen, touch integrated module and control circuit are separately fixed to the housing. The touch integrated module is connected to the control circuit, and the touch integrated module can be triggered to send an instruction to the control circuit. The display screen is connected to the control circuit, showing the operational information of the instruction after the data processing of the control circuit. The touch controller having a display screen can simultaneously control at least two drivers.
