Abstract: A wireless detecting apparatus and a wireless detecting system are disclosed. The wireless detecting apparatus is applicable to a golf club. The apparatus includes an accelerometer, a terminal wireless module and a terminal microprocessor module. The accelerometer is used to generate an accelerating variable and output an electric signal. The terminal microprocessor module receives the electric signal, and generates a golf swing dynamic signal according to the electric signal, and outputs the golf swing dynamic signal to a wireless remote device via the terminal wireless module. The wireless remote device includes a remote wireless module, a remote displayer and a remote microprocessor module. The wireless remote device receives the golf swing dynamic signal via the remote wireless module and controls the remote displayer for displaying the golf swing dynamic signal. The wireless detecting apparatus and the wireless remote device form the wireless detecting system.

Abstract: A crosslinked positioning method sets one of the intercommunicated positioning devices as a master and the remaining ones as slaves through a crosslink allocation. The method includes the steps of searching several devices at the same time, receiving IDs and comparing the IDs. The device with a higher ID is a master, and the other devices with a lower ID are slaves. The master and slaves perform a data link through a search mode, a call mode, a frequency hopping mode, a transmission power adjusting mode or a correction time mode. After the data link is accomplished, positioning data of the master and the slaves are displayed simultaneously on a screen.

Abstract: A sends and receives advertisement data through wireless LAN. The location based service system includes a plurality of commercial store base stations and at least one client end apparatus operatively connected to the commercial store base stations through the wireless LAN. Therefore, consumer can know the commodity information of the commercial store when he is within an accessible region of the commercial store base station. Moreover, the consumer can know desired commodity information and geographic location of the store with client end apparatus thereof.

Abstract: A many-to-many crosslink communication positioning apparatus includes a CPU, a RF circuit, a GPS circuit, an electronic compass circuit and a display device. Several devices are searched for their serial numbers at the same time, and the serial numbers are compared. The device with a large serial number is a master, and the device with a small serial number is a slave. Data including the search mode, call mode, frequency hopping mode, transmission power adjusting mode and correction time mode of the master and the slave are linked, and then related position and distance of the master and the slave are displayed on a screen of the communication positioning apparatus.
