Abstract: The robotic arm operating system includes a control device, a plurality of joint devices and a brake release monitoring device. The control device is used to generate an operation instruction. The joint device is coupled to the control device. Each joint device includes a motor and a driver. The drivers of the joint devices receive the operation instruction to generate corresponding multiple unlocking signals. The unlocking signals are used to release a braking state of the motors of the corresponding joint devices. The brake release monitoring device is coupled to the control device and the joint devices, and includes a plurality of monitoring circuits. When one of the plurality of monitoring circuits does not receive the corresponding unlocking signal, the brake release monitoring device notifies the control device that the operation instruction is not allowed.

Abstract: A printing system includes a controller and a thermal printing head including multiple driving elements and an integrated transmission control interface. The thermal printing head is coupled to the controller. The driving elements are configured to print. The integrated transmission control interface coupled to the controller and driving elements is configured to receive from the controller at least one of a compensation data, a printing data, a clock signal, a data signal, a latch signal or a start-heating signal, and send to driving elements the at least one of the compensation data, the printing data, the clock signal, the data signal, the latch signal or the start-heating signal.

Abstract: A solar tracking device for solar panel includes a barrel body, a light transmitting unit, a projecting unit, a photosensor unit, and a lens. The light transmitting unit is disposed at a first end of the barrel body oriented toward the sun. The light transmitting unit has a light-transmittable crossing point provided at a center thereof. The projecting unit is an opaque member arranged between the first end and a second end of the barrel body. The photosensor unit is arranged to one side of the projecting unit, so that the projecting unit is located between the light transmitting unit and the photosensor unit. The photosensor unit has a locating center preset at a center of the projecting unit. The lens is arranged between the projecting unit and the photosensor unit. The barrel body is a telescopic barrel enabling the solar tracking device to switch between different operating angle modes.

Abstract: A light emitting diode lens structure includes a lens having an upper section and a lower section. The lower section is provided with a light emitting diode accommodation part. The upper section is coated with a specular reflection layer to form a reflecting surface facing the light emitting diode accommodation part. An illumination apparatus with the light emitting diode lens structure includes a lampshade, a locking module, an electrode module, and a light emitting diode. The lampshade has a reflecting light surface and an aperture. The locking module is coupled on the lampshade and has a through hole corresponding to the aperture. The electrode module is coupled on the locking module and corresponds to the through hole. This design provides a significant reduction in glare to reduce eyestrain.
