Abstract: A support block for a steam turbine casing, a related assembly and apparatus. Various embodiments include a steam turbine casing support block having: a body portion sized to substantially fill a pocket in a steam turbine casing, the body portion having a greater length than a depth or a width; a set of tabs extending from the body portion, each of the set of tabs sized to substantially fill a corresponding slot in the steam turbine casing, wherein the set of tabs are located at a radially outwardly facing wall of the body portion; and a pin hole on a bottom surface of the body portion for receiving a retaining member.

Abstract: Systems, methods and apparatuses for an intraocular imaging system are disclosed comprising an optical coherence tomography (OCT) system. The OCT system has an imaging range that may enable substantial portions of an eye or even a whole eye to be imaged. The OCT system may be coupled to an operation microscope, such that, for example, a surgeon can visualize ocular structures like the human crystalline lens and other ocular structures such as the cornea and/or vitreous while surgical instruments are in the field of view.

Abstract: A method for content playback and recording may include using a computer to obtain media content from a recorded medium. Concurrently with obtaining the media content, the method may include reencrypting the encrypted media content using a secondary encryption key and storing the reencrypted media content in a storage device.

Abstract: A centerline support bar for steam turbine component assembly, installation, and/or alignment is disclosed. In one embodiment, the support bar includes a body portion configured to be disposed across a centerline of a steam turbine, the body portion configured to transversely connect to a steam turbine component; and a first flange extending from the body portion and configured to contact a steam turbine casing, wherein the steam turbine support bar is configured to non-affixedly join the steam turbine casing to the steam turbine component.

Abstract: An ice protection system and method are provided that facilitate the prevention or reduction in ice formation upon an aerodynamic surface. The ice protection system may include an aerodynamic surface that includes a susceptor formed of a ferromagnetic material that is located proximate an outer mold line of a leading edge of the aerodynamic surface. The ice protection system may also include at least one induction coil and a signal source configured to provide alternating current to the at least one induction coil to thereby generate an electromagnetic field. The electromagnetic field creates an eddy current in the susceptor so as to heat the leading edge of the aerodynamic surface. A corresponding ice protection method is also provided.

Abstract: A method and apparatus processes multi-channel audio by encoding, transmitting or recording “dry” audio tracks or “stems” in synchronous relationship with time-variable metadata controlled by a content producer and representing a desired degree and quality of diffusion. Audio tracks are compressed and transmitted in connection with synchronized metadata representing diffusion and preferably also mix and delay parameters. The separation of audio stems from diffusion metadata facilitates the customization of playback at the receiver, taking into account the characteristics of local playback environment.

Abstract: A method for content playback and recording may include using a computer to obtain media content from a recorded medium. Concurrently with obtaining the media content, the method may include reencrypting the encrypted media content using a secondary encryption key and storing the reencrypted media content in a storage device.

Abstract: Methods and systems for fluid stabilization are provided. The system includes a first electrical field generator positioned adjacent to a first passage. The first electrical field generator imparts a first electrical field to a fluid flowing through the first passage such that first particles and second particles entrained in the fluid are charged to a first polarity. A first collector positioned within the first passage collects the first particles charged in the fluid. A second electrical field generator positioned adjacent to a second passage is downstream from the first electrical field generator. The second electrical field generator imparts a second electrical field to the fluid discharged from the first passage and substantially neutralizes the second particles entrained in the fluid.

Abstract: A stationary component includes an outer ring including a first plenum, a first passageway, and a second plenum defined therein. The first passageway extends between the first plenum and the second plenum. An airfoil is disposed radially inward of the outer ring. The airfoil includes a second passageway defined therein. The second passageway is coupled in flow communication with the second plenum.
