  • Publication number: 20140270744
    Abstract: A active stabilization system and a method for correcting a pointing direction of a camera to compensate for translational movements of the camera are described. The system actively stabilizes a pointing direction of the camera in accordance with a commanded pointing angle. A distance from the camera to a filming target is determined and one or more translational measurements associated with a translational movement of the camera are derived. A correction update is calculated as a function of at least the distance and the one or more translational measurements. The commanded pointing angle of the camera is adjusted based on the correction update to retain the filming target within a field of view of the camera.

  • Publication number: 20140267810
    Abstract: A method for introducing controlled disturbance into a video being captured by a camera housed by an active stabilization system executing a stabilization process to stabilize a pointing angle of a camera housed by the active stabilization system in accordance with a commanded angle is provided. The method comprises acquiring a measurement associated with a movement of the active stabilization system, determining a noise value based on the acquired measurement, and injecting the noise value into the stabilization process causing the process to adjusting adjust the pointing angle of the camera in a direction away from the a commanded pointing angle of the camera using the noise value.

  • Publication number: 20140267778
    Abstract: Apparatuses and methods for controlling a gimbal and other displacement systems are disclosed herein. In accordance with one or more embodiments of the invention, a pointing angle of a camera attached to a gimbal may be controlled based, at least in part, on one or more control signals provided by a controller. The control signals may be used to compensate for displacement of the camera, to add perceived displacement of the camera, to selectively align a pointing angle of the camera and/or to allow a pointing angle to be manually determined.

  • Publication number: 20140169570
    Abstract: Described herein are techniques for artificially enhancing spaciousness in a hearing aid to improve the music listening experience. Such spatial enhancement is produced by doing signal processing in the hearing aid that mimics the acoustic effects of well-designed concert halls. The same techniques can also be applied to improving the experience of listening to recorded music reproduced and amplified over a speaker system, or to music streamed to the direct-audio input of a hearing aid.

  • Publication number: 20130344242
    Abstract: The use of self-assembled block copolymer structures to produce advanced lithographic patterns relies on control of the orientation of these structures in thin films. In particular, orientation of cylinders and lamellae perpendicular to the plane of the block copolymer film is required for most applications. The preferred method to achieve orientation is by heating. The present invention involves the use of polarity-switching top coats to control block copolymer thin film orientation by heating. The top coats can be spin coated onto block copolymer thin films from polar casting solvents and they change composition upon thermal annealing to become “neutral”. Top coats allow for the facile orientation control of block copolymers which would otherwise not be possible by heating alone.

  • Publication number: 20130280497
    Abstract: The present invention involves the use of random copolymer top coats that can be spin coated onto block copolymer thin films and used to control the interfacial energy of the top coat-block copolymer interface. The top coats are soluble in aqueous weak base and can change surface energy once they are deposited onto the block copolymer thin film. The use of self-assembled block copolymers to produce advanced lithographic patterns relies on their orientation control in thin films. Top coats potentially allow for the facile orientation control of block copolymers which would otherwise be quite challenging.

  • Publication number: 20130266780
    Abstract: The present invention includes a diblock copolymer system that self-assembles at very low molecular weights to form very small features. In one embodiment, one polymer in the block copolymer contains silicon, and the other polymer is a polylactide.

  • Publication number: 20130209757
    Abstract: The present invention uses vacuum deposited thin films of material to create an interface that non-preferentially interacts with different domains of an underlying block copolymer film. The non-preferential interface prevents formation of a wetting layer and influences the orientation of domains in the block copolymer. The purpose of the deposited polymer is to produce nanostructured features in a block copolymer film that can serve as lithographic patterns.

  • Patent number: 7688851
    Abstract: A method and system for accessing a remote real communication port (“COM port”) from a server blade in a server blade chassis by creating a virtual COM port in the server blade. A basic input/output system (BIOS) controller monitors an internal COM port in the server blade for communication traffic. Upon detecting the communication traffic, the BIOS controller reroutes the traffic to a virtual USB COM port created by the BIOS controller chipset. The virtual USB COM port directs the communication traffic to an internal universal serial bus (USB) device in the server blade. The USB device then forwards the traffic to an Ethernet media access controller (MAC) input/output (I/O) on a sideband channel to a remote system, which passes the communication traffic to a real COM port in the remote system.

  • Patent number: 7684711
    Abstract: An optical transmission system comprises two optical fibers carrying optical signal traffic between two terminals, and a plurality of optical repeaters coupled to the two fibers each repeater having a permanently connected passive high loss loop back circuit between the two fibers. One terminal includes a transmitter, which launches a pulsed supervisory signal on a dedicated supervisory wavelength into one optical fiber, and a receiver, which detects a portion of the supervisory signal looped back from each repeater in order to identify the existence and location of faults in the transmission system. The pulsed supervisory signal is of sufficiently short duration such that portions of the signal returned from each repeater do not overlap with one another and interference with the counter-propagating traffic is avoided by utilizing a dedicated supervisory wavelength. Each return pulse is integrated sequentially by a single detector and processed by heterodyne reception and synchronous demodulation.
