Abstract: A high-insulation multilayer planar transformer (1) includes a pair of iron cores (20) and a circuit board integration (10a). The circuit board integration (10a) is stacked between the iron cores (20) and has a through hole (100a). The circuit board integration (10a) includes a first to a third insulating layers (11a, 12a, 14a) and a first to a second coil windings (13a, 15a). The first and third insulating layers (11a, 14a) include at least two insulating plates (111a, 141a) stacked with each other respectively. The second insulating layer (12a) includes at least one insulating plate (121a). The coil winding (13a, 15a) is disposed between the adjacent insulating layers and surrounds the through hole (100a) planarly. Therefore, the reinforced insulation requirement of safety regulations may be achieved.

Abstract: The present disclosure relates to a grouped multi-device anti-loss warning system with multiple warning devices categorized as one group in which the warning devices granted an identical Group ID and not divided into mater/slave devices communicate with one another; a warning message can be activated among these warning devices in which contacts are disabled for broadcasting a notification that a group member (warning device) is considered as being out-of-touch within a preset period and fulfilling an anti-loss effect by mutual reminders among warning devices in the same group.

Abstract: A method and an apparatus for encrypting/decrypting packet data of a precise time synchronization protocol and a time synchronization system are illustrated. The method is suitable for the time synchronization system using a precise time protocol. The time synchronization system includes a master node and a slave node, wherein the slave node synchronizes its time with the master node. In the method for encrypting/decrypting packet data of the precise time synchronization protocol, an encryption/decryption hardware device is disposed on the hardware protocol layer of each of the master node and the slave node. The hardware protocol layer is under the data link layer, and includes the data link layer. A synchronization message is encrypted by using the encryption/decryption hardware devices of the master node to generate a frame data, and the frame data is decrypted by using the encryption/decryption hardware devices of the slave node to obtain the synchronization message.

Abstract: Provided are a network slave node and a time synchronization method using precision time protocol-like (PTP-like) in a network. The network slave node includes a packet detection unit for detecting whether the slave node receives or sends a synchronization protocol packet and recording a synchronization protocol packet receiving time and a synchronization protocol packet sending time; a hardware clock; and a control unit controlling the packet detection unit and the hardware clock. The control unit reads out the packet receiving time and the packet sending time from the packet detection unit and informs a local master node. The local master node calculates a time offset between the local master node and the slave node, and informs the control unit. The control unit adjusts the hardware clock based on the time offset so that the local master node and the slave node are time synchronized.

Abstract: In a communication network, a network connection apparatus accepts timing information of a grand master to achieve timing synchronization. Next, the network connection apparatus requests slave nodes to be in timing synchronization with itself to achieve the timing synchronization. Even when the grand master is removed or crashed, when a new slave node is added, or when a hack node tries to hack the communication network, the network connection apparatus still periodically requests the slave nodes to be in timing synchronization with itself so that the timing synchronization inside the communication network is not negatively affected.

Abstract: The present invention includes a method for speech encoding and decoding and a design of speech coder and decoder. The characteristic of speech encoding method relies on the type of data with high compression rate after the whole speech data is compressed. The present invention is able to lower the bit rate of the original speech from 64 Kbps to 1.6 Kbps and provide a bit rate lower than the traditional compression method. It can provide good speech quality, and attain the function of storing the maximum speech data with minimum memory. As to the speech decoding method, some random noises are appropriated added into the exciting source, so that more speech characteristics can be simulated to produce various speech sounds. In addition, the present invention also discloses a coder and a decoder designed by application specific integrated circuit, and the structural design is optimized according to the software.

The direct memory access system comprises: a first bus interface, a second bus interface, a FIFO memory, an iSCSI CRC module and a direct memory access controller. According to the invention, the iSCSI CRC module is mounted in the direct memory access system to automatically calculate the iSCSI cyclic redundancy codes and update the digest of the iSCSI protocol data unit during directly accessing the iSCSI protocol data unit between the iSCSI protocol and the TCP/IP protocol. Therefore, the direct memory access system of the invention can reduce the loading of CPU and the latency of repeatedly reading the iSCSI protocol data unit so as to raise the speed and efficiency for processing the iSCSI cyclic redundancy codes and to reduce the reading memory time and the waiting time.
