Abstract: An electrical motor activation method for an electric motor including a rotor, connected to a motor shaft, and a stator having brushes. The stator comprises multiple commutator laminations for the commutation of windings disposed on the rotor and is activated by a pulsed or linearly controllable power source. The motor shaft is connected to a radially driven load, in particular a pump, which has a nonlinear torque curve via a motor revolution. A waviness signal is obtained from a voltage potential applied to the motor and/or from the motor current and rotor position information is obtained from the curve of said waviness signal.

Abstract: Iterative (nondeterministic) optimization of aerodynamic and hydrodynamic surface structures can be accomplished with a computer software program and a system using a combination of a variable encoding length optimization algorithm based on an evolution strategy and an experimental hardware set-up that allows to automatically change the surface properties of the applied material, starting with the overall shape and proceeding via more detailed modifications in local surface areas. The optimization of surface structures may be done with a computing device for calculating optimized parameters of at least one (virtual) surface structure, an experimental hardware set-up for measuring dynamic properties of a specific surface structure, and an interface for feeding calculated parameters from the computing device to the experimental set-up and for feeding measured results back to the computing device as quality values for the next cycle of the optimizing step.

Abstract: A system used for calibrating a direction-finding system. A device may include a signal receiver array. The signal receiver array may be utilized to determine the direction of arrival for signals emitted by other devices, and therefore, may be used to resolve the direction towards another device using the received signal. For example, an external tag may be utilized to emit a wireless signal usable inducing a response in each signal receiver of the signal receiver array. The device may also include one or more sensors usable in determining device orientation and/or a change in device orientation. The combined signal receiver response information and orientation information may be recorded at various instants as the device is moved for use in calibrating the antenna array.

Abstract: In a microfluidic processor with integrated active elements for handling process media, the active elements act by changes in their volume, swelling degree, material composition, their strength and/or viscosity. The procedures to be performed are defined already by the constructive configuration of the microfluidic processor by an appropriate logic connection of the individual active elements defined in their function, by the sequence of the temporal activation of the individual elements, and with respect to their processing speed and their precision. The process is enabled by action of a substantially non-directional collectively acting environmental parameter, in particular, the presence of a solvent or environmental temperature or both.

On depressurization of a pressure medium chamber in the spring accumulator brake cylinder, ventilation of a spring accumulator chamber of the spring accumulator brake cylinder, from the pressure medium chamber of the operating brake cylinder, is effected. A chambers is provided on the side of a valve piston in the valve, facing away from a control chamber, which, with an open valve, connects a first working connections to this chamber and, hence, to a second working connection, arranged axially on the front side of the valve, by means of a passage provided in the valve piston.

Abstract: In a motor vehicle having a front-end structure, a front bulkhead separates the front-end structure from an interior space, and a braking unit fixed to the front bulkhead has a master brake cylinder and a brake booster. The braking unit is pivotable about a pivot axis which runs through the front bulkhead, with an arrangement for pivoting the braking unit being arranged at a distance from the pivot axis and interacting with components arranged in the front-end structure in the event of a vehicle collision. In order to reliably reduce the risk of injury to a driver of a motor vehicle in the footwell region in the event of a vehicle collision, a transmitting element is provided to prevent a relative movement between the arrangement for pivoting the braking unit and the pivot axis.

Abstract: Plays videos in conjunction with a “cutlist” utilized to modify the video. Videos include any visual media such as online or streaming video, broadcast television or movies, digital media files having a video component or DVDs. The videos may originate from any location such as online, on YOUTUBE.COM®, cable television, or a local resource such as a digital media file or DVD. Cutlists may include “mashups” and “cuts”. Mashups add content and include additional user generated input such as text, audio, commentary, graphics, avatar overlays, advertisements or other video. Cuts allow skipping of video and are time windows or scenes that are not to be viewed. The modified video may be viewed on any device associated with a video display. Cutlists may be shared among users to modify the performance of original video source without modifying the video itself, therein bypassing any copyright issues.

Abstract: In a method for producing and/or adjusting an electromagnetically controllable actuator which is appropriate to control the flow of a fluid, at least one electromagnetic property of the actuator is measured, and the measured electromagnetic property itself or a quantity derived therefrom is used as an actual value for a control of a correcting variable. This correcting variable is taken into account directly to produce or adjust the actuator. A suitable device for this calibration comprises a control circuit and a mounting location, where the actuator can be mounted into the device, and is designed to adjust at least one mechanical property of the actuator by way of the correcting variable.

Abstract: The present invention is embodied in a digital communication system where multiple media data sources are time multiplexed into a packetized data stream, each packet having an assigned priority and the packetized data stream transmitted in substantially the order of assigned priority. At both the transmit side, and the receive side, audio packets are given priority processing over video packets, which in turn have priority over text/graphics data packets. Continuous real time audio playback is maintained at the receiver by delaying the playback of received audio in a first in/first out (FIFO) buffer providing a delay at least equal to the predicted average packet delay for the communication system. Optionally, the average system delay is continuously monitored, and the audio playback delay time is adjusted accordingly. Audio playback is slowed or accelerated in order to shrink or grow the difference in time between the sender and receiver.
