| 20100008108 | NOVEL ADAPTIVE SLOPE COMPENSATION METHOD FOR STABILIZING A CONTINUOUS CONDUCTION MODE CONVERTER - An embodiment of the invention relates to a power converter operable in a continuous conduction mode and a discontinuous conduction mode that includes a current-sense circuit element configured to produce a current-sense signal dependent on a current in an inductor of the power converter, and a difference circuit configured to produce a difference signal representing a difference of the current-sense signal and a signal representing an output characteristic of the power converter such as an output voltage. The difference signal is constrained to be above a difference signal threshold value. A slope compensation circuit is configured to produce a slope-compensated signal comprising a sum of the difference signal and the current-sense signal. A controller is configured to control a duty cycle of a power switch of the power converter in response to the slope-compensated signal by comparing the slope-compensated signal with a voltage threshold controlled by a feedback circuit. | 01-14-2010 |

| 20100258775 | Automatic Rising Jack Stand - Jack stands having support arms that automatically rise to meet lifted loads are disclosed herein. According to one embodiment, a jack stand includes a base having a collar, a support arm, a locking mechanism, and a lifting mechanism. The support arm is movable within the collar and has a plurality of teeth defining grooves and ridges. The locking mechanism has a handle and a stopper and is rotatably coupled to the base at an axis of rotation for movement between a first position where the stopper engages at least one of the grooves to restrict the support arm from moving downwardly, and a second position where the support arm is movable upwardly and downwardly. The lifting mechanism is coupled to the base and is in communication with the support arm to automatically raise the support arm relative to the collar when the locking mechanism is moved to the second position. | 10-14-2010 |
