Abstract: An anti-interference ranging method and an anti-interference ranging apparatus are provided. The method includes: detecting, by a first light detection and ranging device, whether a light detection process is interfered by a second light detection and ranging device in the ranging system; delaying, by the first light detection and ranging device, the light detection process for a preset time period if it is detected that the light detection process is interfered by the second light detection and ranging device; and acquiring, by the first light detection and ranging device, detection data collected in the light detection process, and processing, by the first light detection and ranging device, the detection data to obtain a ranging result if it is detected that the light detection process is not interfered by the second light detection and ranging device.

Abstract: A touch pen comprises a penholder, an electrically conducting core, a flexible covering and fabric covering. The electrically conducting core is coupled to the penholder. The electrically conducting core is ensheathed in the flexible covering, while the fabric covering wraps around the flexible covering, wherein either flexible covering or fabric covering has electrical conductivity. In the present invention, the flexible covering and the fabric covering are shaped under the pressure exerted by the electrically conducting core and a touch panel so as to increase the contact area between the touch pen and the touch panel and, meanwhile, the fabric covering is capable of reducing the friction between touch pen and the touch panel, thereby improving the sensitivity and touch effect.
