Patents by Inventor Glenn Chance Dunlap, III

Glenn Chance Dunlap, III has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7541795
    Abstract: A regulator is provided. In one embodiment, the regulator operates as follows. During steady-state conditions, the switching frequency is maintained substantially constant. During start-up and/or in response to an over-current event, the reference voltage is attenuated. For example, in one embodiment, during a soft-start, the reference voltage ramps upward. During the soft-start, the switching frequency is attenuated in proportion to the attenuation of the reference voltage. The switching frequency is attenuated by skipping a number of pulses that is proportional to the reference voltage attenuation, or through another method. In another embodiment, a dynamic over-current protection scheme is employed.

  • Patent number: 6965223
    Abstract: A circuit and method for enabling a rapid adjustment of a reference voltage during a disable period such as a fault condition, shutdown condition, and the like, of a voltage regulator is described. A soft start circuit that is arranged to couple a reference voltage input of an error amplifier to a portion of an output voltage avoiding high current surges and optimizing start up time is modified to include a low resistance switch that provides a path for a reference node capacitance to rapidly discharge. The faster discharge may allow the reference voltage to match the output voltage even when the switch is activated for a very brief interval. This in return allows the output voltage to start up in a controlled manner after a disable period.

  • Patent number: 6093138
    Abstract: A method is provided for making a universal packaging bag that has a window through which a component on a product can be visually perceived. The method provides for the bag to be used on differently designed bagging machines, such a right-handed bagging machine or a left-handed bagging machine.

  • Patent number: 6033112
    Abstract: A universal flexible packaging bag is provided that contains a stack of products, such as a plurality of disposable absorbent training pants, in which each product has a component, such as a graphic on a front panel of a training pant, that is to be visually perceived through a window in the bag. The bag is uniquely designed to accommodate differently designed bagging machines, such as a right-handed bagging machine and a left-handed bagging machine, so that a stack of products can be positioned in the bag such that the component is visible through the window.
