    摘要： An electrical device including an electrical power cord secured to a base of the electrical device by using a plug having a pair of resilient prongs. The plug is inserted into an opening in the base to secure a strain reliever on an end of the electrical power cord into the opening. The resilient prongs flex towards each other when the plug is inserted into the opening. The prongs return to their original positions after passing through the opening and seat the plug in the opening. When seated, the plug secures the strain reliever into the opening thereby securing the electrical power cord to the base.

    摘要： An apparatus is disclosed for rotating a structural profile quickly and easily on a single spindle drill line without the use of a crane. The apparatus has two arms which can lay flat or create any angle less than 180 degrees between the two. The apparatus can move horizontally along the drill line and can lift the structural profile vertically for movement and during rotation. This will allow a drill machine operator to rotate large and heavy structural profiles on a drill line and position them with the datum blocks in order to drill the different sides without the need for an overhead crane or other lifting device and without any additional labor to assist with manual flipping and positioning.

    摘要： A processor receives interrupts of a same type from hardware. The processor determines a rate at which the interrupts are being received. The processor compares the rate at which the interrupts are being received to a threshold rate. In response to determining that the rate at which the interrupts are being received is greater than the threshold rate, the processor sends just the first received interrupt to firmware for processing. All other of the interrupts are not sent from the processor to the firmware but instead are suppressed by the processor. By comparison, in response to determining that the rate at which the interrupts are being received is less than the threshold rate, the processor can send all the interrupts from the processor to firmware for processing.

    摘要： A radio frequency receiver comprising a receiver module, an intermediate frequency (“IF”) module, a synthesizer module and a controller module. The receiver module receives a radio frequency signal and provides a baseband in-phase signal and a baseband quadrature signal eliminates a sideband of the in-phase and quadrature signals to create a first and a second signal, downconverts the first and second signal to a first and a second IF signal, and selects one of the first or second IF signals. The IF module receives the first or second IF signal, performs analog-to-digital conversion on the first or second IF signal, and demodulates the digitally converted. If signal The synthesizer module receives a programmable reference signal, downconverts the reference signal to an IF feedback signal, downconverts the reference signal to a baseband feedback signal provides the IF feedback signal to the IF module, and provides the baseband feedback signal to the receiver module. The controller module samples the digitally converted IF signal and provides the programmable reference signal to the synthesizer module to thereby provide a demodulated output signal.
