Compensation for low drop out voltage regulator
ActiveUS6977490B1High gainDesign moreElectric variable regulationAudio power amplifierVoltage regulation
A voltage regulator apparatus includes an error amplifier that amplifies a voltage difference between a reference and a sampled output voltage of the voltage regulator apparatus. A driver amplifier has an input that is responsive to the amplified voltage difference to produce a gate driving voltage at its output. An output transistor having a drain, a gate, and a source is also included. The gate is responsive to the gate driving voltage to produce a regulated output voltage at the source. To stabilize the voltage regulator apparatus, a Miller compensation capacitor is provided to feed a sample of the regulated output voltage back to the input of the driver amplifier; and additionally, an Ahuja compensation circuit is provided to feed back a portion of the regulated output voltage back to the input of the driver amplifier.

Animate load bearer radial adjuster device for cargo transport carriers
InactiveUS7513018B2Easy accessFacilitates manipulationSnap fastenersTravelling sacksCombined useRegulators (device)
A radial adjuster device is provided for use in conjunction with cargo transport carriers worn by animate load bearers. The radial adjuster device allows an animate load bearer to adjust each laterally positioned cargo transport carrier shoulder strap or other such support structure single-handedly, or alternatively to adjust each shoulder strap simultaneously using each hand to engage and rotate the radial adjuster device to achieve a desired position or balance of the cargo transport carrier. The radial adjuster device simplifies and optimizes cargo transport carrier adjustment to facilitate animate load bearers in properly positioning cargo transport carriers, and consequently avoiding the injury and discomfort associated with bearing improperly balanced cargo transport carriers. The spooling mechanism of the inventive radial adjuster device eliminates the inconvenience, unsightliness, and potential hazards associated with free-hanging strap ends of cargo transport carriers.

Each time the first count reaches a first count threshold, the electro-kinetic system is temporarily shut down for a predetermined period, the second count is incremented, and the first count is re-initialized. The electro-kinetic system restarts after the predetermined period. When the second count reaches a second count threshold, the electro-kinetic system is shut-down until a reset condition is satisfied.

Active noise control system in unrestricted space
The adaptive speed to changes in a primary source noise is increased through a noise detecting means feeding parallel multi-passband means and multi-transverse adaptive filter means, where each adaptive filter has its own individual adaptive step size means adjusted automatically according to the signal strength at each passband output. The output from each of the multi-adaptive filter means drives a secondary canceling source generating means where each multi-adaptive filter means is automatically adjusted to produce minimum sound in its passband at an error detecting means. Alternatively, the output from the noise detecting means is negated through a negation means, passed through a plant neutralization inverse means and an inverse delay means before driving the secondary source generating means. The secondary source output is aligned and match in amplitude to that of the primary sources, through a delay buffer means and an amplitude regulator means, which are adjusted successively until the output at the error detector means is a minimum.

Flow regulator device
InactiveUS20090151800A1Reduced opening sizeIncrease opening sizePipe supportsOperating means/releasing devices for valvesEngineeringMechanical engineering
A fluid flow regulator of the present invention comprises in combination a stationary hollow duct housing having a first end and a second end through which fluid flows. The device also incorporates a movable member aligned concentric with the duct having an end essentially similarly shaped and sized to the first end of the housing. The member may be spaced apart from the duct so that fluid can enter the duct housing through an opening defined by the space between the end of the member and the first end of the duct, with the movement of the member serving to change the size of opening. The movement of the member is controlled by the movement of a float located within the duct. The position of the float can be preset by the operator of the invention so that when fluid flow into the duct is at a predetermined amount the float will remain stationary, and when the fluid flow increases above such predetermined level the float will be moved in the direction of the fluid flow and when fluid flow into the duct is below said predetermined amount, the float will move the member opposite the direction of fluid flow.
