  • Publication number: 20110031200
    Abstract: A collapsible rack includes a middle frame, a first lateral frame, a second lateral frame and at least one shelf. The middle frame includes a first pair of ears formed thereon and a second pair of ears formed thereon. The first lateral frame includes a pair of screws driven through the first pair of ears, thus pivotally connecting the first lateral frame to the middle frame. The second lateral frame includes a pair of screws driven through the second pair of ears, thus pivotally connecting the second lateral frame to the middle frame. The shelf includes a first edge pivotally connected to the middle frame and a second edge for engagement with the first and second lateral frames when the collapsible rack is in an extended position.

  • Publication number: 20100048314
    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.

  • Patent number: 7595751
    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.

  • Publication number: 20090164121
    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.

  • Patent number: 7093728
    Abstract: A shelf includes a plurality of support stands each having a periphery formed with a plurality of elongated flanges. Each of the flanges has two opposite sides each formed with a reduced neck. Thus, the flanges of each of the support stands are combined with the racks in various different angles, so that the angle and mode of assembly of the shelf can be changed arbitrarily so as to fit the requirement of different sites, such as the house, the exhibition place or the like, thereby enhancing the versatility of the shelf.

    Abstract: A shelf includes a plurality of support stands each having a periphery formed with a plurality of elongated flanges. Each of the flanges has two opposite sides each formed with a reduced neck. Thus, the flanges of each of the support stands are combined with the netted racks in various different angles, so that the angle and mode of assembly of the shelf can be changed arbitrarily so as to fit the requirement of different sites, such as the house, the exhibition place or the like, thereby enhancing the versatility of the shelf.
