  • Patent number: 10595443
    Abstract: An open-ended screwless positioning module of an access apparatus includes an external frame body and an operation handle pivotally connected to the external frame body. The external frame body has a base, two arms, positioning bumps, an installing portion, an unlocking switch and a pivot portion. The arms extend downwards from the base in which a holding space for receiving the access apparatus is defined by the base and the arms. The positioning bumps are integrally formed on the arms for engaging with securing holes of the access apparatus. The installing portion is disposed on an upper surface of the base, the unlocking switch is movably assembled on the installing portion, and the pivot portion is disposed to a main body of the operation handle.

  • Patent number: 9760509
    Abstract: A memory storage device including a first and a second connection interface units, a memory control circuit unit and an interfacing circuit is provided. The first connection interface unit and the second connection interface unit are electrically connected to an input/output channel of the memory control circuit unit. The interfacing circuit is disposed between the memory control circuit unit and at least one of the first and the second connection interface units. The interfacing circuit is configured to provide determination information of an electrically connecting configuration between at least one host system and the at least one of the first and the second connection interface units. The memory control circuit unit is configured to provide different operation functions to the at least one host system based on the determination information.
