  • Patent number: 9836066
    Abstract: In hydraulic systems having rotating-stationary component interfaces, a bore pressure regulating mechanism is provided to interact with the hydraulic fluid in a control volume to maintain a hydraulic fluid pressure in a longitudinal shaft bore at or approximately equal to a supply pressure when a gear shaft rotates within the control volume. In one aspect, the bore pressure regulating mechanism minimizes vortex flow of the hydraulic fluid induced by the rotation of the gear shaft. In another aspect, the bore pressure regulating mechanism provides a direct feed of pressurized hydraulic fluid proximate an opening of the longitudinal shaft bore through an end surface of the gear shaft, and thereby minimizes the opportunity for the hydraulic fluid to be forced into vortex flow by the gear shaft in the area of the longitudinal shaft bore.

  • Patent number: 9402144
    Abstract: An apparatus for changing an audio scene has a direction determiner and an audio scene processing apparatus. The audio scene has at least one audio object having an audio signal and associated meta data. The direction determiner determines a direction of a position of the audio object with respect to a reference point based on the meta data of the audio object. Further, the audio scene processing device processes the audio signal, a processed audio signal derived from the audio signal or the meta data of the audio object based on a determined directional function and the determined direction of the position of the audio object.

  • Patent number: 8462966
    Abstract: An apparatus for calculating filter coefficients for a predefined loudspeaker arrangement has a multi-channel renderer. The multi-channel renderer calculates a filter coefficient for each loudspeaker of a virtual loudspeaker arrangement, being different from the predefined loudspeaker arrangement, based on a property (e.g. position or type) of a virtual source of an audio object to be reproduced by the predefined loudspeaker arrangement. Further, the multi-channel renderer determines an adapted filter coefficient for a loudspeaker of the predefined loudspeaker arrangement based on one or more calculated filter coefficients of one or more loudspeakers of the different virtual loudspeaker arrangement.

  • Patent number: 8239579
    Abstract: A dual loop (PLL/DLL) data synchronization system and method for plesiochronous systems is provided. A dual loop data serializer includes a phase lock loop (PLL) and a delayed lock loop (DLL) configured with a phase shifter in the feedback path of the PLL. The dual loop serializer locks to the input of the DLL instead of the local reference. Thus, the DLL adjusts the frequency from the PLL so that it matches the desired data rate. Each loop may be optimized for jitter tolerance with the net effect generating a synthesized clean clock (due to narrow bandwidth filtering) and VCO noise suppression (due to wide bandwidth filtering). A dual loop retimer includes a dual loop serializer (PLL/DLL) and a clock recovery DLL. The retimer resets the jitter budget to meet transmission requirements for an infinite number of repeater stages.
