A data object management method and a data object management system are provided. The data object management method includes the following steps. Generate a space allocation list according to an operation parameter of a space consuming device. The space allocation list records information about a plurality of storage spaces. Update the space allocation list and a target storage space. The target storage space is one of the storage spaces. Send a playlist corresponding to the space allocation list when a reading request corresponding to the space consuming device is received.

In a hybrid codec apparatus for data broadcasting, an encoder divides a source file into N sections, generates N principal encoded data after coding on a first finite field and k additional encoded data after coding on a second finite field, then transmits a group of coefficient encoded data and the N+k encoded data to a decoder. The decoder merges the group of coefficient encoded data and the N+k encoded data, and decodes the N principal encoded data on the first finite field. When the decoder fails to decode the N principal encoded data, the decoder uses the k additional encoded data to assist the data decoding on the second finite field. After the decoding, a recovered source file is produced.

A wireless communication network, including a destination node, a first node transmitting a first routing message, wherein the first node has a first routing table including a first entry for the destination node, and the first entry includes a first list field for child node(s). The network further includes a second node generating and transmitting a second routing message according to the first routing message, wherein the second routing message includes a second parent node field, and the second parent node field is marked as the first node that transmitted the first routing message. The first node further receives the second routing message and stores a first mark in the first list field for child node(s) of the first entry after determining that the second parent node field of the second routing message is marked as the first node, and the first mark denotes the second node.

A method and a system for motion tracking, capable of tracking a trajectory of a movable object by an architecture having at least three accelerometers arranged in a predefined structure. The trajectory, displacement and rotational angle of the movable object are determined by ways of extrapolation, numerical calibration and vector transformation according to the acceleration signals detected by the at least three accelerometers.

In a routing method, a control element firstly forms a forwarding table and an exchanging table according to a routing table. Next, a first forwarding element receives a packet, and then obtains a label from the forwarding table according to a destination address of the packet, and determines to output the packet from the first forwarding element or a second forwarding element according to the label. If the packet is to be outputted from the first forwarding element, it is directly outputted to the destination address of the packet; otherwise the second forwarding element receives the packet and the label. Next, the second forwarding element obtains a next forwarding path from the exchanging table according to the label to forward the packet. The control element and the first and second forwarding elements constitute a routing system.
