Efficiency booster circuit and technique for maximizing power point tracking
InactiveUS20060174939A1Reduce voltageConsiderable amount of energyBatteries circuit arrangementsPV power plantsSolar cellPoint tracking
The present invention provides an efficiency booster circuit and accompanying switch mode power conversion technique to efficiently capture the power generated from a solar cell array that would normally have been lost, for example, under reduced incident solar radiation. In an embodiment of the invention, the efficiency booster circuit generates an output current from the solar cell power source using a switch mode power converter. A control loop is closed around the input voltage to the converter circuit and not around the output voltage. The output voltage is allowed to float, being clamped by the loading conditions. If the outputs from multiple units are tied together, the currents will sum. If the output(s) are connected to a battery, the battery's potential will clamp the voltage during charge. This technique allows all solar cells in an array that are producing power and connected in parallel to work at their peak efficiency.

An adjustable alarm device for windows and doors is installed between the door or window frame and the door or window sash. The longitudinal axis of the alarm device is preferably horizontal. When engaged, movement of the door or window in an open direction will activate the alarm. The body of the alarm device is elongate, tubular and telescoping. The body comprises an outer tube that receives an inner tube. The body of the alarm device may be locked in an extended position by way of a cam mounted on the inner tube and positioned within the body so that when the inner and outer tubes of the body are twisted about their longitudinal axis, the cam body will engage the inner surface of the outer tube in a releasable frictional locking engagement. The alarm device is coupled to one end of the inner tube.

Method of controlling rechargeable battery power and a power source apparatus
InactiveUS20060087291A1Appropriate settingAvoid excessive dischargeCharging stationsSecondary cells charging/dischargingBattery chargeMemory effect
The method of controlling rechargeable battery power is a method that includes limiting the amount of usable power during rechargeable battery charging and discharging, determining a rechargeable battery current-voltage characteristic function based on rechargeable battery charging and discharging current flow and voltage, finding a limiting discharging current Imax and / or a limiting charging current Imin from a prescribed minimum voltage Vmin to prevent over-discharging and / or a prescribed maximum voltage Vmax to prevent over-charging and their intersection with the current-voltage characteristic function, and controlling current such that discharging current greater than or equal to Imax and / or charging current less than or equal to Imin does not flow through the rechargeable batteries. In this fashion, the amount of usable power can be limited considering factors such as the memory effect, and the rechargeable battery can be used to its maximum capability within the range of safe operation.

Torque-based powertrain control for vehicles
ActiveUS7275518B1Prevent over-chargingImproved torque controlElectrical controlInternal combustion piston enginesEngineeringPowertrain control
A system and method for controlling a vehicle powertrain having an internal combustion engine include determining a difference between a desired engine torque and a current engine torque, adjusting the difference based on a stored torque offset corresponding to a current engine speed, and controlling the engine to produce a torque corresponding to the adjusted torque difference. The stored torque offset is adjusted when the engine is operating in a predetermined engine speed range based on a steady-state difference between the desired and current engine torque to reduce the steady-state difference to zero. The adjusted torque difference may be limited by a maximum-engine-torque-available parameter and a minimum-engine-torque-available parameter, which is based on an operating temperature, such as the engine coolant temperature. The system and method may also include controlling spark to rapidly reduce current engine torque to the adjusted torque difference value.

A method and system are provided for estimating state of charge of a cell having a positive electrode, for example of a lithium phosphate type, the charge profile of which includes a range of state of charge between about 30 and about 90% in which variation of voltage is 10 times less rapid than for a state of charge higher than 90%. Determination of state of charge for a state of charge greater than 90% is based on either the use of a calibration relationship between cell voltage and state of charge when a current is passing through the cell that is less than a predetermined threshold value and its voltage has stabilized, or on the use of coulometry the result of which is corrected taking into account the accuracy of the current sensor.
