20100060219 | BLOWER MOTOR FOR HVAC SYSTEMS - A blower motor assembly having a variable speed motor that is suitable for direct, drop-in replacement in a residential HVAC (heating, ventilation, and air conditioning) system that employs a PSC motor. The blower motor assembly includes at least a neutral input and two hot AC line connections, one for connection to the heating power source and the other to the cooling power source. A sensing circuit senses which of the inputs is energized by sensing either voltage or current on the inputs. The sensing circuit delivers a corresponding signal to a motor controller to control the speed of the variable speed motor. The blower motor assembly may also be equipped with additional hot AC inputs, more than one neutral line, and several sensing circuits for sensing current or voltage in the hot inputs and/or the neutral lines for controlling various aspects of the variable speed motor. | 03-11-2010 |
20100068070 | FLOW CONTROL FOR FLUID HANDLING SYSTEM - A method of correcting fluid flow offset for an uncharacterized fluid handling system including a motor. The method includes running the motor at a reference fluid flow demand using generic coefficients, and changing fluid flow demand from the reference fluid flow demand until the motor signals a power limit condition. When the motor signals the power limit condition, the fluid flow demand is noted. The operational fluid flow demands are scaled by a ratio of the noted fluid flow demand to the reference fluid flow demand. | 03-18-2010 |

20150349685 | SYSTEM AND METHOD FOR STARTING AN ELECTRIC MOTOR - A system and method for starting electric motors. A controller attempts to start a motor without applying a brake to the rotor. If the motor fails to start, the controller applies a strength of braking and then again attempts to start the motor. If the motor still fails to start, the controller iteratively increases the strength of braking and attempts to start the motor until a maximum strength of braking and/or a maximum number of attempts to start the motor is reached. Alternatively, a sensing system first determines whether the rotor is rotating. If the rotor is rotating, the sensing system determines the speed of rotation, the controller determines a strength of braking that will halt the rotation based on the speed of rotation, applies that strength of braking to halt the rotation of the rotor, and then attempts to start the motor. | 12-03-2015 |
20150365026 | SINGLE-SHUNT CURRENT SENSING FOR MULTI-PHASE MOTOR - A motor controller for providing a three-phase alternating current (AC) signal to a three-phase motor. The motor controller uses current feedback from a single shunt to monitor or control the three phase AC signal. The motor controller may include a three-phase DC to AC power inverter, a single-shunt current sensor, and a processor. During individual duty cycles when two or more phase signals are too close to each other, the processor may shift one of the phase signals in time so that its leading or trailing edges are a predetermined conflict time away from each other. Then, the processor may sample current from the single-shunt current sensor to determine currents of two of the three phase signals and then calculate current of a remaining one of the three phase signals. Sample times may depend on pulse widths and shifting of the phase signals. | 12-17-2015 |

20100037932 | SYSTEM FOR SIMULTANEOUS TABBING AND STRINGING OF SOLAR CELLS - A method for stringing photovoltaic (PV) cells together and a system for the combined tabbing and stringing of photovoltaic (PV) cells for assembly into solar cell arrays. Multiple ribbons are first soldered simultaneously (or nearly so) to the front and back surfaces of individual PV cells (tabbing). After tabbing, PV cells are then loaded into a stringer subsystem which solders the front side ribbons of a first PV cell to the back side ribbons of the neighboring PV cell to form strings of PV cells wired in series. The tabber stringer system then loads completed strings into a frame containing a solar cell array being manufactured. The dual-ribbon method of PV cell interconnection reduces the electrical resistance between the cells in a string, thereby raising the solar cell array output power. | 02-18-2010 |
20100182421 | METHODS AND APPARATUS FOR DETECTION AND CLASSIFICATION OF SOLAR CELL DEFECTS USING BRIGHT FIELD AND ELECTROLUMINESCENCE IMAGING - Methods and apparatus for integrated, in-line metrology of solar cells involve three distinct inspection and testing operations, prior to string and module assembly. Two of the inspections are performed by image analysis using bright field illumination. The third inspection involves electroluminescence imaging, where luminescence in the solar cell is achieved by inducing a forward bias in the solar cell, and analyzing a resulting grayscale image for defects. | 07-22-2010 |
20100319754 | PHOTOVOLTAIC MODULE CONFIGURATION - Improvements for a photovoltaic module (PVM) include the use of a micro-embossed, reflective optical film located in areas of the PVM not covered by the solar cells. The optical film is configured to reflect light incident upon the PVM onto the solar cells and may be formed from a polymeric material. Further enhancements include the use of a compliant heat conducting polymeric film on back sides of the solar cells and a heat conductive polymeric film deposited on an aluminum foil to form a composite film, which effects heat transfer from the solar cell junctions and improves cell efficiency. A top glass with selective frequency and anti-reflective coatings may also be used. Further, improved interconnects for the solar cells eliminate sharp edges, helping to avoid any potential for encapsulant tearing or tab “push-through” and resultant shorting during lamination. | 12-23-2010 |
