| 20100171742 | Method and Apparatus for Information Gathering and Display - Graphical variable indicators convey information gleaned from data gathered from a user interface or storage. In an example embodiment, a polygon drawn from values of the respective variable indicators conveys the information. In a medical implementation, the polygon drawn from patent related data quickly and easily conveys the status of a patient. Preferably, the graphical variable indicators include previous, current, and desired values for the variables. Thus, a preferred embodiment includes a polygon for each of the previous, current, and desired values for the variables. | 07-08-2010 |

| 20080319623 | Apparatus and method for power hop detection and mitigation - A method and system of detecting power hop of a vehicle involves generating signals, including a current signal and a previous signal, indicative of the current longitudinal acceleration of the vehicle, calculating the period and amplitude of the signals, determining if the combined period and amplitude of the current signal exceeds a first predetermined value, and determining whether the combined period and amplitude of the current signal exceeds a second predetermined value greater than the first predetermined value. The method may also involve determining if the amplitude of the current signal exceeds a predetermined percentage of the amplitude of the previous signal. Power hop is detected when the combined period and amplitude of the current signal exceeds the first predetermined value as well as the second predetermined value, and possibly also when the amplitude of the current signal exceeds the predetermined percentage of the amplitude of the previous signal. | 12-25-2008 |

| 20080277413 | Toy Water Gun with Selectable Pulse and Stream Discharge Nozzles - A toy gun is disclosed that may have a pressurized elastomeric supply bladder in fluid communication with an elastomeric pulse bladder via a trigger valve. The pulse bladder may also be in fluid communication with a pulse nozzle via a pulse valve that is operatively connected to the pulse bladder so that the pulse valve moves from a closed position to an open position when the pulse bladder expands. When the supply bladder is filled with pressurized liquid and the trigger valve is opened, pressurized liquid from the supply bladder is forced into the pulse bladder. As the pulse bladder expands, the expansion eventually causes the pulse valve to open and cause a burst of liquid to be discharged from the pulse bladder through the pulse nozzle. As the pulse bladder contracts during the burst of liquid, the pulse valve returns to the closed position so that the pulse bladder can continuously cycle through the sequence of filling with pressurized liquid and opening the pulse valve to release a burst of liquid as long as the trigger valve remains opened and the supply bladder forces pressurized liquid to the pulse bladder. | 11-13-2008 |

| 20110260628 | SYSTEM AND METHOD FOR ILLUMINATING A COMPONENT OF AN ELECTRONIC DEVICE - The disclosure describes a system and method for controlling a light for a component of an electronic device. An embodiment uses brightness evaluation zones and progresses through one or more of the zones to determine whether and when to activate the light for given conditions of ambient light. In doing so, the embodiment sets a current brightness evaluation zone for the device and sets an activation status of the light level to an activation value associated with the current brightness evaluation zone. The embodiment compares an ambient light level for the device to the current brightness evaluation zone. Evaluation loops are provided to test and change the current brightness evaluation zone against the detected ambient light. The light may be a backlight. | 10-27-2011 |

| 20110101937 | Voltage Regulator with Virtual Remote Sensing - An automatic voltage compensation circuit in a voltage regulator compensates the output voltage for a voltage drop along lines leading to a remote load. A load capacitor is connected across the load for providing a low impedance across the load during a test phase of the regulator. In one embodiment, during the test phase, the load current is changed up or down a small percentage (e.g., 10%). As a result, the regulator voltage changes due only to the line resistance since the load is bypassed by the load capacitor. The voltage drop at full load current is then derived by detecting the change in regulator output voltage (a fractional voltage drop) and multiplying it. The normal mode is resumed, and the derived voltage drop is added to the regulator output by either compensating the feedback loop or by adding the voltage drop to the output of the regulator. | 05-05-2011 |

| 20080238400 | Bandgap voltage and current reference - Circuits and methods that improve the performance of reference circuits are provided. A reference generator circuit maintains a substantially constant output current over an extended temperature for use as a reference. Output current fluctuations caused by a poorly specified power source or process variations are minimized or eliminated. | 10-02-2008 |
| 20080272844 | CLASS AB FOLDED-CASCODE AMPLIFIER HAVING CASCODE COMPENSATION - A class AB folded-cascode amplifier having improved gain-bandwidth product, comprises a differential input circuit including a differential transistor pair coupled to a source of tail current and responsive to a differential input signal for conducting a first current, a cascode circuit coupled to the differential input circuit for supplying a second current thereto, and a class AB output stage. A compensation circuit is configured for feeding back mutually complementary compensation signals from an output node to the differential input circuit. Another compensation circuit is configured for feeding back a signal from the output of the output stage to the input of the output stage. | 11-06-2008 |
| 20090015070 | Paralleling voltage regulators - Circuits and methods for paralleling voltage regulators are provided. Improved current sharing and regulation characteristics are obtained by coupling control terminals of the voltage regulators together which results in precise output voltages and proportional current production. Distributing current generation among multiple paralleled voltage regulators improves heat dissipation and thereby reduces the likelihood that the current produced by the voltage regulators will be temperature limited. | 01-15-2009 |
| 20090121770 | METHOD FOR CLAMPING A SEMICONDUCTOR REGION AT OR NEAR GROUND - A clamping circuit clamps a voltage received by an n-type semiconductor region without using a Schottky transistor. The clamping circuit includes a current mirror as well as first and second bipolar transistors. The current mirror receives a first current and supplies a second current in response. The first current is received by the first bipolar transistor, and the second current is received by the second bipolar transistor. The difference between the base-emitter junction voltages of the first and second bipolar transistors, in part, defines the voltage at which the n-type region is clamped. To start-up the circuit properly, current is withdrawn from the base/gate terminals of the transistors disposed in the current mirror. The circuit optionally includes a pair of cross-coupled transistors to reduce the output impedance and improve the power supply rejection ratio. | 05-14-2009 |
