Title: Sound processing system for configuration of audio signals in a vehicle
Inventor: FURGE KENNETH CARL
IPC: H04S1/00
Filed: 2005-08-05
Granted: 2012-12-18
Abstract: A sound processing system for a vehicle includes a sound processor that is configured to mix at least one real audio input signal to form at least one virtual output signal. At least one audio signal that is available to drive at least one loudspeaker may be formed using the combination of the virtual output signal and the real audio input signal. The virtual output signal may be post processed to form a predetermined frequency range of the audio signal prior to being combined with the real audio input signal. The audio signal may be created by mixing the real audio input signal with the post processed virtual output signal. Alternatively, the audio signal may be formed by mixing the real audio input signal to form a real audio output signal, and then summing the real audio output signal with the post processed virtual output signal. Mixing may be performed with a crossbar mixer included in the sound processor.

Filed: 2004-05-21
Granted: 2012-07-17
Abstract: A lancet device (11) for obtaining a blood sample from a finger or at an alternate site of a patient. The lancet device includes a body (34, 41) and a lancet (131), the lancet being movable between a retracted position in which the lancet tip (137) is disposed within the body and an extended position in which the lancet tip extends beyond the body.

Title: Transmission of protection commands to a remote tripping device
Inventor: STRITTMATTER MICHAEL
IPC: H04L27/32
Filed: 2005-12-02
Granted: 2014-08-12
Abstract: The present invention is concerned with the transmission of protection commands to a remote tripping device over an analog signal link with a limited number of tones or frequencies (F1, F2, F3, F4). Different operating principles involve a number of frequency detectors (41, 42, 43, 44) depending on the number of commands (A, B, C, D) that are to be transmitted either alone or in combination. In order to transmit a maximum number of protection commands with a minimum number of tones/detectors, two of the abovementioned distinct operating principles are assigned at least one common tone. A prioritizing mechanism is established for preferring certain related protection commands belonging to a common application. Upon reception of a signal coding a combination of protection commands, it is possible to detect individual protection commands in accordance with different minimum safety and/or security values. A protection command can thus always be transmitted optimally for the intended application, i.e. the parameters of safety and/or security, dependability and transmission time are individually configurable for the protection command.

Title: Hopper car side construction and method
Inventor: FORBES JAMES W
IPC: B61D7/00
Filed: 2006-12-01
Granted: 2012-10-02
Abstract: A hopper car has arcuate side sheets that are bent over the forming members of the structure to give a generally outwardly bulging shape. The upper margin of the side sheet is kinked inwardly of the radius of curvature of the larger portion of the side sheet more generally, such as may tend to impose a bending moment on the large, relatively thin side sheet panels. This may in turn tend to urge or bias those panels to a bulging position or shape, rather than a sagging, deflected, or inwardly dented position.

Title: Rotor blade for a wind power installation
Inventor: WOBBEN ALOYS
IPC: F03D80/00
Filed: 1999-12-09
Granted: 2009-07-28
Abstract: Rotor blades for wind power installations are known in many different forms. In a wind power installation the rotors or the rotor blades thereof represent the main source of sound. For reasons relating to acceptance and noise prevention laws, the aim should/must be that of minimising the levels of sound emission as wind power installations are often also set up in the proximity of residential accommodation. The levels of sound emission which hitherto occur with a wind power installation or a wind power converter also mean that wind power installations are faced with resistance from populated areas because of the sound they produce and for that reason such installations can be accepted sometimes with difficulty or not at all as authorities responsible for planning permission refuse permission for wind power installations because of the existing environmental requirements, noise also being an environmentally polluting factor. Therefore the object of the invention is further to improve the noise emission of wind power installations. Wind power installation rotor blade comprising means for reducing the sound produced by a rotor blade, wherein the means is formed by a fluid-repellent layer and/or surface which is provided at least on a surface portion of the rotor blade.
