Abstract: A panel inspection device and inspection method is provide. At least an image capturing element is disposed above or below a spacing between a first conveyer and a second conveyer. During a panel is conveyed from the first conveyer to the second conveyer, the image capturing element captures the image of the panel as the panel passes through the spacing.

Abstract: An address learning method for a network device having a plurality of connection ports, at least one of which is electrically connected to a terminal device. The method includes a fetching process, a hashed-address generating process, a data registering process and an address registering process. The fetching process fetches an address data string from a first memory unit by a programmable logic device (PLD). The hashed-address generating process generates a hashed-address by the programmable logic device. The data registering process writes the address data string into an address data table. The address registering process writes the hashed-address into a hashed-address table. A network device for performing the address data learning method is also disclosed.

Abstract: Positioning apparatus applied on equipment with one or a plurality of single axles is fixed on two bases opposite to each other. Adjusting device is located in each base and corresponding to each cross or single axle, which is configured for adjusting the position of the cross or single axle in a direction parallel to the base. Fixing device is configured for fixing the adjusting device on the base. The fixing device is moved in one direction vertical to the adjusting device adjusted in another direction.

Abstract: A substrate cassette suitable for storing at least a substrate is provided. The substrate cassette includes a top plate, a bottom plate, multiple supports and multiple suspending arms. The top plate is opposite to the bottom plate, and the supports are connected to the top plate and the bottom plate to form a storage space. The suspending arms are fixed on the supports, and each suspending arm extends from the support to the inside of the storage space. Wherein, one of the suspending arms is fixed on each support at the same horizontal level for carrying the substrate. The substrate cassette has multiple substrate input and output entrances, and each substrate input and output entrance is located between the adjacent supports. Besides, a transport system is also provided.

Abstract: A panel positioning device utilizes fixed positioning elements and the trench so as the fixed positioning device may apply to the panel with different sizes. The positioning element may slide in the trench to the corresponding location and be fixed there. The location where the positioning element fixed in is a gap between the panel and the printed wiring board (PWB) or at an edge of the panel.

Abstract: A network switch device includes a processor, a memory module, a PCI Bus, a switch fabric module, and an inspection module. In this case, memory module is cooperated with the processor. The switch fabric module has a plurality of first connecting terminals and connects to the processor through the PCI Bus. The inspection module has a plurality of second connecting terminals and a plurality of third connecting terminals. The second connecting terminals connect to the first connecting terminals respectively.

Abstract: A redundant link management switch for use in a stack of switches forming a closed-loop link topology, including a stacking module, a processor and a management module. The stacking module has an uplink port for connecting a next-higher switch in the stack and a downlink port for connecting a next-lower switch in the stack. The processor instructs the stacking module to disable a downlink control bus within the downlink port when receiving a disconnect command, and instructs the stacking module to enable the downlink control bus when receiving a reconnect command. The management module asserts the disconnect command if a link status, received from the processor, indicates that the redundant link management switch and the stack of switches are stacked into the closed-loop link topology. Additionally, the management module asserts the reconnect command to recover a redundant link if the management module detects that the closed-loop link topology is changed.

Abstract: A linking apparatus is provided for establishing interconnection for stackable network switch. The linking apparatus includes an electronic circuit configured for providing stacking interconnection between two stackable network devices. A miniature GBIC-compliant (Gigabit Interface Connector) connector locates at an end of the electronic circuit. And two USB (Universal Serial Bus) connectors are arranged as a stacking module at the other end of the electronic circuit for providing uplink and downlink connections.

Abstract: Disclosed is a floater energy generator which includes a sealable water tank to create inside the water tank a water and an air pressure smaller than an external atmospheric pressure, such that water inside the tank will not overflow the tank from a lower manifold. Floaters are sent into the water tank via the lower manifold and are allowed to float and stay in a space left in a top portion of the water tank, such that when an upper outlet of the tank is opened, the floaters are allowed to fall out of the tank to impact on blades of a blade wheel disposed below the water tank, causing the blade wheel to rotate continuously and generates kinetic energy output. The floaters and water in the water tank can be recovered for repeated use.

Abstract: A semi-automatic, adjustable picking and weeding implement comprises a stationary prong and an adjustable prong with which a horizontal handle, a stop pad, a spring, two horizontal, partly-threaded shafts, two stop pegs and four nuts are associated so that the implement can be vertically pushed into soil, and one prong can be slantingly pressed toward the other to pluck up weeds easily and promptly. After that, the prong that is slantingly pressed can automatically recover its vertical position. In order to weed various sizes of weeds, the span between the stationary prong and the adjustable prong can be modified. Essential methods for using such an implement are also disclosed.

Abstract: A weeding and picking tool includes a shaft member having a handle formed on an upper portion of the shaft member and two stick members bifurcated on a lower portion of the shaft member, with a first stick member straightened to be longer than a second stick member of which a hook portion is formed on a bottom of the second stick member adapted to hold weed roots on the hook portion when digging the tool into the earth, whereby upon a rotation of the tool about the first straight stick member, the weed roots will be wound on the two stick members for an easier pulling and removal of the weeds from the earth.
