Abstract: A packet transmission system, a packet transmission method, a packet update method, a host apparatus, and a computer program product thereof for the packet transmission system are provided. The packet transmission method comprises the following steps: transmitting a first positioning packet that has a first message serial number; receiving the first positioning packet; generating a temporary packet that has a second message serial number; determining that the first message serial number is smaller than the second message serial number; transmitting the temporary packet; receiving the temporary packet and updating the first message serial as the second message serial number; and transmitting a second positioning packet that has the second message serial number. Thereby, the system not only prevents repeat transmission, but also enhances positioning reliability by using two-way transmission.

Abstract: A network address assigning and allocating method and a routing method for a long-thin wireless network are provided. First, a plurality of nodes in the long-thin wireless network is classified into a plurality of clusters, in which nodes ranging from a child node of a bridge node to a next bridge node are classified as the same cluster. Then, a network address is assigned to each of the nodes, in which the network address includes a cluster ID and a node ID, the cluster ID is used for identifying the clusters and for routing a packet between the clusters, and the node ID is used for identifying the nodes in each of the clusters and for routing a packet in the cluster. Thereby, the routing and network transmitting efficiency of the long-thin wireless network can be improved.

Abstract: A backlight module and a method for manufacturing a base thereof are provided. The backlight module base includes a back plate and a frame. The back plate has a plate body and at least one sidewall, which includes a wall body and a folding structure bending from the top of the wall body. The folding structure, the plate body, and the wall body together enclose a groove. The frame is formed on the plate body and adjacent to an inner surface of the sidewall. A part of the frame is embedded into the groove. The engagement between the frame and the groove increases the contact area between the frame and the back plate to improve the connection strength. In addition, the folding design of the sidewall increases the rigidity of the whole structure.

Abstract: A network address assignment method and a routing method for a long thin ZigBee network are provided. The routing method includes the following steps. A network address is assigned to each node of the ZigBee network, wherein each network address includes a cluster ID and a node ID. The cluster ID is used for identifying a plurality of clusters of the ZigBee network. The Node ID is used for identifying a plurality of nodes of each cluster. When a packet is transmitted, check whether the current node holding the packet and the destination node are in the same cluster. If they are in the same cluster, the packet is routed within the cluster according to the node ID of the destination node and a predetermined algorithm. If they are not in the same cluster, the packet is routed among the clusters according to the cluster ID of the destination node.

Abstract: A method, a network apparatus, and a tangible machine-medium thereof for detecting a looping network packet are provided. A receiving module receives a network packet. A memory stores a routing table comprising an address related variable, a sequence number related variable and a radius related variable. A determining module determines whether the network packet is a looping network packet by comparing the parameters of the routing table with those of the network packet. With these arrangements, the routing loop caused by transmission of the network packets can be detected using current network structures.

Abstract: A communication apparatus originally transmits data packets via a first channel based on a first beacon interval. A memory thereof records the first beacon interval. A receiving interface thereof receives information of a second channel. A processor thereof determines whether the second channel has been used according to the information.

Abstract: A system, a method, a computer program product, and a computer readable medium thereof for a new node joining a wireless network are disclosed. The wireless network system comprises a plurality of child nodes and a plurality of father nodes corresponding to those child nodes. Each of the child nodes and each of the father nodes can send a beacon packet, which comprises an absolute time index and a relative time index. When the new node collects the absolute time indexes and relative time indexes of neighboring child nodes, it can calculate the occupied absolute time index quickly and derive its absolute time index from the unoccupied absolute time index. Based on the same reason, when applying the system to a scheduling algorithm, the scheduled result can be derived quickly. In addition, the system can prevent the accumulated error. The system can be applied to a low-rate wireless network.

Abstract: A silicon bulk-micromachining technology is used to fabricate a GMR filter by exploiting the structure of a suspended silicon nitride (SiNx) membrane on the silicon substrate. A first silicon nitride (SiNx) thin film and a second silicon nitride (SiNx) thin film are formed on opposite sides of the silicon substrate. A first opening is defined in the first silicon nitride (SiNx) thin film, and a grating structure is defined in the second silicon nitride (SiNx) thin film. By etching off a portion of the silicon substrate exposed from the first opening until a portion of the second silicon nitride (SiNx) thin film is exposed from the first opening, a light path space is defined.

Abstract: A ZigBee network system, method with roaming function, and computer readable medium thereof are provided. The ZigBee network system comprises a first node, a second node, a coordinator and a first roaming node. The first node, the second node and the coordinator are connected directly or indirectly. The first roaming node connects to the first node wirelessly. The method comprises the following steps. The first roaming node transmits a roaming-request packet when the first roaming node roams within a connecting range of the second node. The second node transmits a roaming-identify packet in response to the roaming-request packet. One of the first node and the coordinator transmits a roaming-confirm packet in response to the roaming-request packet. The second node transmits a roaming-response packet in response to the roaming-confirm packet. The first roaming node connects to the second node wirelessly after the first roaming node receives the roaming-response packet.

Abstract: A power-saving wireless network, a packet transmitting method for use in the wireless network, and computer readable medium therefor are provided. The wireless network comprises a PAN coordinator, a receiving node and a transferring node. When the transmitting node has a packet planed to be transmitted to the receiving node which is in a sleep mode, the packet is alternatively transmitted to the PAN coordinator. As soon as the receiving node wakes from the sleep mode, all packets are transmitted to the receiving node from the PAN coordinator. After the packets are all successfully transmitted, the receiving node turns back to the sleep mode subsequently. Thereby, the performance of the wireless network would not be restricted to the sleep period and memory capacity. Thus, the nodes in the wireless network would greatly facilitate saving power.

Abstract: A wireless communication apparatus, system, method and computer readable medium therefor for transmission between a parent node and a child node are provided. The child node transmits a first packet to the parent node via point-to-point transmission. When the parent node tries to transmit a second packet to the child node, a synchronization signal is transmitted first and then the second packet is transmitted to the child node via broadcast transmission after a certain period. If the child node fails to receive the second packet during the certain period, the child node sends a signal to the parent node. The parent node re-transmits the second packet to the child node via point-to-point transmission.
