20110154775 | Geo-Synthetic Composite Insulation for Roofing - A geo-synthetic composite insulation panel for roofing applications is provided. The panel comprises a bottom layer made of an insulating material and a top layer made from a geo-textile laminated on top of the bottom layer. The geo-textile material provides an absorption zone for any adhesive used to glue waterproof membranes onto the insulation panel. This allows a better redistribution of loads on the insulation panel and increases the resistance of the material to punctures that the surface of the waterproof membrane may be subject to. The material, by its nature, will enhance the whole integrity of the roofing system. | 06-30-2011 |

20110057573 | LED BALLAST POWER SUPPLY HAVING DIGITAL CONTROLLER - A power supply for an LED lamp has a set of coupled coils, primary-side power circuitry including a converter power switch for conducting input power, and secondary-side power circuitry including a dimming power switch. Power control circuitry includes converter control circuitry which generates a converter control signal for the converter power switch to maintain a desired undimmed level of lamp current at a normal operating value of a lamp voltage. Dimming control circuitry generates a dimming control signal for the dimming power switch to pulse-width modulate the lamp current at a duty cycle corresponding to a desired dimming. Operation of the converter control circuitry is modified during dimming to prevent an automatic increase of the lamp voltage in response to a decrease in lamp current, avoiding undesirable overshooting of the lamp current and providing more accurate and effective control over dimming operation. | 03-10-2011 |
20110234000 | DISTRIBUTED POWER SUPPLY SYSTEM WITH DIGITAL POWER MANAGER PROVIDING DIGITAL CLOSED-LOOP POWER CONTROL - A power supply system includes a digital power manager and multiple power blocks each conveying regulated power to a respective load. The power blocks include the power part of non-isolated DC/DC converters, signal sampling and conversion circuits to provide analog voltage signal representing output voltage, output current, temperature, etc., and driving circuits to receive pulse width modulation (PWM) signals and drive switching devices. Closed-loop voltage control and protection functions for the power blocks are integrated into the digital power. The digital power manager includes a non-volatile memory containing registers, including a digital power manager configuration register, a power block set-up register, and a power block monitor register, as well as a user-definable space. The digital power manager programs and monitors operation of each power block, and may also include a user interface, such as an I2C interface, for receiving programming data from a host user system and send monitoring data thereto. | 09-29-2011 |
20130188399 | DC-TO-DC CONVERTER HAVING SECONDARY-SIDE DIGITAL SENSING AND CONTROL - A DC/DC converter for use in power supply applications employing multiple parallel-connected converters employs a digital controller referenced to the secondary or output side of an isolation boundary and having non-isolated direct connections to secondary side components. The controller directly monitors output voltage and output current and uses feedback control techniques to precisely control these values in a desired manner. The DC/DC converter can implement so-called “droop” current sharing with increased accuracy arising from the secondary-side digital control, so that a desired balanced sharing of current across multiple converters can be achieved. The converter uses calibration establish accurate set points, and any of a variety of additional functions/features to attain operational goals. | 07-25-2013 |
20140292297 | POWER SUPPLY HAVING SELECTABLE OPERATION BASED ON COMMUNICATIONS WITH LOAD - A power supply includes signaling circuitry coupled to output terminals for engaging in bidirectional communications with a load. A controller is capable of conducting the bidirectional communications and selecting among different operating modes for the power supply based on the communications. The modes may include a constant-current mode suitable for applications such as battery charging and power LED lamps, and a constant-voltage mode suitable for a variety of conventional uses such as powering electronic circuitry. The signaling circuitry may include a power switching transistor in series with the load, which is pulsed in a binary fashion to transmit communications to the load. A signal-forming resistor in parallel with the power switching transistor develops a signaling voltage monitored by the controller to receive communications from the load. | 10-02-2014 |
20140340941 | DROOP CURRENT SHARING POWER CONVERTER WITH CONTROLLED TRANSITIONS BETWEEN REGULATION SET POINTS - A regulated switching power converter generates a converter output having first and second regulated output values under corresponding operating conditions. The converter output transitions between the first and second output values in response to transition of a trigger signal in a transition window between first and second trigger values. A transition step function is based on transition amplitude, transition interval and number of steps, the transition amplitude being a difference between the first and second regulated output values, and the transition interval being a difference between the first and second trigger values. The transition step function generates a step-like transition signal based on values of the trigger signal between the first and second trigger values. During operation in the transition window, the step-like transition signal is included in the regulation reference value to generate a step-like transition of the converter output between the first and second regulated output values. | 11-20-2014 |

20140033435 | PIECE OF FURNITURE, SUCH AS AN ADJUSTABLE BED, HAVING AN ADJUSTABLE PLATFORM - An adjustable bed includes a main frame which supports a mattress platform, a fixed frame base having wheels mounted thereto for displacement thereof on a floor surface, and a lift mechanism interconnecting the main frame and the fixed frame base. The lift mechanism supports the main frame and is actuated to displace and position the main frame between a fully collapsed position and a fully elevated position relative to the fixed frame base without any longitudinal displacement of the bed. The main frame, the fixed base and the lift mechanism collapse into a low profile bed configuration in the fully collapsed position, such that the mattress platform is located at a minimum vertical height of at most 9 inches above the floor surface. | 02-06-2014 |

20100192961 | TRACKABLE REFERENCE DEVICE FOR COMPUTER-ASSISTED SURGERY - A surgical reference device for use with a computer-assisted surgery system comprises an engaging member adapted to engage directly on soft tissue of a body part such that substantially no relative movement is possible between the engaging member and a bone element of the body part. A trackable member is attached to the engaging member and comprises a detectable element for being located and tracked in three-dimensional space by the computer-assisted surgery system to measure a position and an orientation of the trackable member in time, whereby the bone element is tracked as a function of the position and orientation of the trackable member. A method for tracking a position and an orientation of a bone element using a computer-assisted surgery system is also provided. | 08-05-2010 |
