  • Publication number: 20210221204
    Abstract: A pickup truck bed cover includes foldable horizontal sections retained on a mounting frame by left and right latches attached under the sections. The latches mounting plates, left and right locks, and left and right operating mechanisms. The operating mechanisms are connected to the locks to pull the locks into disengagement with the mounting frame allowing the sections to be folded. Connecting members connect the operating mechanisms. When a handle of one of the operating mechanism is being twisted, both the left and right locking blocks are simultaneously retract to disengage with the mounting frame. When the handle is released, the left and right locks extend to engage the mounting frame. The rotation of the handles may be coupled to the locks by sliding cylinders having spiral surfaces engaged by inside protrusions in the handles. Springs inside the handles bias the sliding cylinders apart to engage he locks.

  • Patent number: 8237055
    Abstract: A circuit board includes an insulation layer, a signal layer disposed on one side of the insulation layer, and a ground plane and a power plane disposed on the insulation layer at a side opposite to the signal layer. The insulation layer forms a separating area arranged between the ground plane and the power plane. At least two signal traces parallel to each other are arranged on the signal layer at one side corresponding to one of the ground plane and the power plane. A width of the signal trace close to the separating area is wider than that of the signal trace away from the separating area.

  • Publication number: 20090071702
    Abstract: A circuit board (10) for reducing a variation in impedance of signal traces thereon includes a first signal plane (30) and a second signal plane (50). The first signal plane includes a first signal trace (31) arranged thereon. The first signal trace has a first width. The second signal plane includes a plurality of second signal traces (51) arranged thereon. An orthographic projection of the first signal trace onto the second signal plane crosses the second signal traces. A width of the first signal trace at positions where the orthographic projection thereof onto the second signal plane at the intersections with the second signal traces transitions to a second width less than the first width of the first signal trace.

  • Publication number: 20020066017
    Abstract: A security system and security method is provided for internet transactions for use in an electronic funds transfer environment and for confirmation of transactions over the internet. The system and method includes online processing of business transactions between at least one buyer, at least one seller, and at least one bank, where each user communicates via the internet and where each transaction incorporates use of a security key, said key comprising: code generated by a code engine independent of the buyer, the seller and the bank, said code being conveyed to the buyer by means independent of the internet, said code being supplied in machine readable format. The code is electronically verified by the seller and banker with the code engine before the transaction occurs.
