  • Publication number: 20220004269
    Abstract: A control circuit for an input device including a micro-switch is provided. The control circuit includes an input circuit, a receiver circuit, a control unit, and a detecting unit. The input circuit includes a first contact and a second contact for electrically connecting to the micro-switch. The receiver circuit includes a third contact and a fourth contact for electrically connecting to the micro-switch. The control unit is electrically connected to the first contact and the third contact for providing an input signal via the first contact to the micro-switch and receiving a switching signal from the micro-switch via the third contact. The detecting unit detects a voltage of the second contact to generate a detecting signal. The control unit receives the detecting signal to determine a type of the micro-switch.

  • Publication number: 20080097971
    Abstract: A peer-to-peer based secondary key search method and system for cluster databases is disclosed. A cluster database has a plurality of storage nodes and each storage node is assigned with a node number and stores a plurality of records. A search term input means couples to the plurality of storage nodes for retrieving a record at a storage node. The search term input means calculates a first node number based on a hash function of a secondary key, queries the first storage node with the secondary key for retrieving a corresponding primary key, calculates a second node number based on a hash function of the primary key, and then queries the second storage node with the primary key for retrieving a corresponding record.

  • Publication number: 20070257431
    Abstract: A 3D jigsaw puzzle includes puzzle pieces each having multiple arms and cutouts structurally complementary to the arms of an adjacent puzzle piece. A surface engagement exists between a peripheral edge defining each of the arms of a puzzle piece and a peripheral edge defining each of the cutouts of the adjacent puzzle piece so that the two adjacent puzzle pieces are combined. A linear engagement exists between opposite sides defining each arm of the puzzle piece and opposite sides defining each cutout of the adjacent puzzle piece.
