Abstract: A method of attaching a line to a support structure includes providing a holder having a fastening section, a side-part section, a closure section, and an engagement section, where the fastening section, the side-part section, and the engagement section define a ring having a gap. The method further includes fastening the fastening section to the support structure, bending the side-part section with respect to the fastening section after the fastening section has been fastened to the support structure, inserting the line through the gap into the ring, and bending the closure section with respect to at least one of the fastening section, the side-part section, and the engagement section such that the closure section engages the engagement section and closes the gap.

Abstract: A holder for attaching a line to a support structure includes a fastening section, a side-part section, a closure section, and an engagement section. The fastening section has a perforation for passage of a fastening element and the fastening section has a receptacle for receiving a nose of a fastening tool.

Abstract: A discharge protection circuit for discharging a full-bridge circuit in a brushless DC fan, wherein the brushless DC fan comprises a control circuit outputting at least one first control signal and at least one second control signal to the full-bridge circuit. The second control signal is a reverse signal of the first control signal; and the full-bridge circuit comprises a first impedance, a second impedance and a switch. The switch has a first terminal, a second terminal, and a third terminal that is grounded. The first terminal and the first impedance are in series connection for receiving the first control signal to control the status of the switch. The second terminal and the second impedance are in series connection and are connected to the input terminal of the second control signal of the full-bridge circuit, and the full-bridge circuit is discharged according to the status of the switch.
