20120031808 | TRAY AND SLIP SHEET FOR TRANSPORTING RUBBER - A tray and slip sheet system for transporting aggregated bales of rubber that provides a manner for thawing rubber being transported, that prevents large rubber bales being transported from fusing together, and that does not damage or contaminate the packaged rubber when a forklift's forks are inserted between two stacked aggregated bales using the tray and slip sheet system. The tray and slip sheet system uses a tray sheet, a slip (when transporting more than one stacked aggregated bale of rubber), and a strap securing system. The tray and slip sheet system provides a system that defines an air recirculation system that allows the first two levels of bales of rubber stacked over the footprint to be defrosted in hot air chambers after winter transport. Systems not having ventilation slits do not allow the first two levels of bales being transported from being completely defrosted. | 02-09-2012 |

20110279155 | Slew rate PWM controlled charge pump for limited in-rush current switch driving - Circuits and methods to limit an in-rush current of a load circuit such as a processor are disclosed. A charge pump is used as driver for switches with pulse modulation width (PWM) control on the duty cycle of a clock. A clock generator generates a ramp signal with variable slope and a reference voltage. The slope of the ramp signal is dependent on the in-rush current of the switch. No dedicated slew rate driver or an external capacitor is required. The main building blocks are: a charge pump used as driver connected to single supply domain, one external (or internal) switch device, a single capacitive feedback between the switch device and the PWM control, and a PWM control comprising a fix frequency voltage triangular pulse generator with variable slope proportional to the in-rush current measurement. | 11-17-2011 |
