摘要： A light-guide assembly and an access control system are provided. The light-guide assembly is used as an interface for touch input. The light-guide assembly includes a light-guide element and a light source disposed on a lateral surface of the light-guide element. The light source emits a first light with a first wavelength. The light-guide element has an upper surface, a lower surface, and an inner layer that is made of a light-transmissive material. The first light enters the light-guide element through the lateral surface and propagates inside the light-guide element for reacting to the touch event occurring on the upper surface. A verification data used in an access control system is formed when the touch event is sensed and identified. A light-activation element of the assembly activates the first light propagating inside the light-guide element and produces a second light that is used to provide a visual effect.

摘要： A method and node for processing messages within an Internet of Things (IoT) network and network packet thereof are provided. Multiple fields of a header of a network packet broadcasted over the IoT network are referred to in the method. When a node receives a network packet broadcasted over the IOT network, it checks if the node's ID is recorded in an ID field of the network packet. The node ID is added to the network packet if the network packet does not record the node ID, and the network packet is then broadcasted to the IOT network; otherwise, the network packet is not broadcasted if the node ID has been recorded in the ID field. The node also performs a function indicated in a function field of the network packet when the node ID is not recorded in the network packet.
