Abstract:
A light path restricting structure is provided, which is applicable in an optical inspection equipment including a light source module for providing a linear light source, a linear camera, a light-splitting unit for refracting light of the linear light source to an object to be inspected and the linear camera, a conveying mechanism for driving the object to be inspected to move, and a case for accommodating the elements. The light path restricting structure is disposed on a transmission path of the linear light source. The light path restricting structure includes a body, which includes a first surface facing the linear light source of the light source module and a second surface facing the linear camera. A plurality of light channels is disposed in the body, and each light channel includes a light inlet and a light outlet disposed on the first surface and the second surface of the body.
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:
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:
An optical disk drive includes a bracket, and a mecha module installed on the bracket. The mecha module includes a mounting plate fixed on the bracket, an optical pick-up head installed on the mounting plate in a slidable manner for reading or writing data in an optical disk, and a spindle motor installed on the mounting plate for rotating the optical disk. The optical disk drive further includes a rotary mechanism connected to the bracket and a base for driving the bracket to rotate into or out of an opening on a housing relative to the base.
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:
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 inspection device and inspection method is provided. 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.
