20140008985 | METHOD AND SYSTEM FOR CONTROL OF ENERGY STORAGE DEVICES - An energy storage control system and method is disclosed. The energy storage control system can include a controller, a circuit defining a plurality of electrical current paths between an input and an output, and a first energy storage device and a second energy storage device electrically coupled in series to one another between the input and output. The control system can also include a first switch device electrically coupled in parallel to the first energy storage device and a second switch device electrically coupled in parallel to the second energy storage device. The controller can be in electrical communication with the first energy storage device and the second energy storage device. The first switch device and second switch device can be operably controlled by the controller. | 01-09-2014 |
20130191043 | Method and Device for Determining an Estimated Value for at least one Measured Variable of a Wind Turbine - The disclosure relates to a method for determining an estimated value for at least one measured variable of a wind turbine. The measured variable represents a bending torque on a blade root of a rotor blade of the wind turbine from a rotor plane. The method includes reading in the measured variable and an angle of attack for the rotor blade. The method further includes adapting a model, which simulates an estimated value of the measured variable on the basis of a modeling instruction for a relationship between the measured variable and the angle of attack. The model is adapted using the read-in measured variable and the read-in angle of attack. The method also includes providing the estimated value for the at least one measured variable using the model. | 07-25-2013 |
20120298233 | MICROFLUIDIC COMPONENT FOR MANIPULATING A FLUID, AND MICROFLUIDIC CHIP - A microfluidic component for manipulating a fluid includes a first substrate, a second substrate, and a third substrate that is configured from a resilient material and arranged between the first substrate and the second substrate. At least one first recess that forms a first control chamber is configured on the face of the first substrate facing the third substrate. At least one second recess that forms a fluid channel is configured on the face of the second substrate facing the third substrate. A second control chamber that is spatially separated from the first control chamber and a control channel that connects the first control chamber to the second control chamber are formed in the first substrate. At least one lateral wall of the second control chamber is configured from resilient material and is deformable by an actuator such that the inner volume of the second control chamber decreases. | 11-29-2012 |
20100163690 | Hose Hanger Assembly having Car Wheel Rim Configuration with Removable Cover Structure - A hose hanger assembly includes a tubular support, at least one mount, a flange structure, and a cover structure. The tubular support defines a first end, a second end, and a storage compartment located therebetween, the first end of the tubular support defining an access opening aligned with the storage compartment. The at least one mount is attached to the second end of the tubular support. The flange structure includes (i) an inner ring member attached in fixed relation to the first end of the tubular support, (ii) an outer ring member spaced apart from the inner ring member, and (iii) and a plurality of links interconnecting the outer ring member and the inner ring member so as to define a plurality of windows, the flange structure being configured to resemble a wheel rim flange. The cover structure is movable between (i) a first position in which the cover structure is located to cover the access opening, and (ii) a second position in which the cover structure is located to expose the access opening. The cover structure possesses a facade structure that includes (i) a first portion configured to resemble a hub cap, and (ii) a second portion configured to have a plurality of protrusions each being configured to resemble a drive portion of a lug nut. The plurality of protrusions is positioned to surround the first portion. | 07-01-2010 |
20100009252 | ACCUMULATOR WITH SEVERAL ACCUMULATOR CELLS - At an accumulator with at least two accumulator cells, which are arranged in an accumulator housing and which are connected electrically with each other by a connector element, at least one of the accumulator cells is connected with the connector element by an electrically conductive adhesive. | 01-14-2010 |
20090260916 | DEVICE AND METHOD FOR ACTIVE NOISE CANCELLATION IN AN EXHAUST GAS CHANNEL OF A COMBUSTION ENGINE - The invention relates to an active noise cancellation device. The invention proposes a device and a method used to cancel the noise in an exhaust gas channel of a vehicle A noise signal is received form the exhaust gas channel, using a sound sensor, a frequency signal which has same amplitude as of noise signal but opposite phase, is generated, the generated frequency signal is acoustically mixed with the noise signal in the exhaust gas channel, using a sound converter, there by reducing the noise in the exhaust gas channel. The device also takes into account the reflection of the sound caused by an obstacle near the exhaust gas channel. A distance measuring device which is external to the active noise cancellation device provides the information about the distance between the obstacle and the exhaust gas channel. Based on the distance, the frequency signal is suitably modified to reduce the effect of sound reflections caused by the obstacle. | 10-22-2009 |
20090213019 | Antenna Device Having A Radome For Installation In A Motor Vehicle - For an antenna device, in particular for a radar antenna device having excitation field and radome in front of it, the thickness of the radome is varied such that a location-dependent phase delay of the emitted or received wave front may be attained. Thus, tilts, in particular for the non-vertical installation of radar devices in motor vehicles, that lead to unwanted radiation lobe deviations, may be compensated for in a simple way. | 08-27-2009 |
