| 20080294786 | NON-BLOCKING OF HEAD END INITIATED REVOCATION AND DELIVERY OF ENTITLEMENTS IN A NON-ADDRESSABLE DIGITAL MEDIA NETWORK - A system, apparatus, and method are directed towards managing entitlement/right revocation and delivery to be performed within a non-addressable media network. Such networks may include for example a client device behind a network address translation (NAT) device, employs non-addressable satellite components, or so forth. A server notifies clients that entitlements, revocations, or the like are available by sending a request for communications with the client. The client initiates a connection to receive the entitlements, or the like, and then disconnects from the server. If the client fails to initiate a connection, the server may continue to send a request for a connection, or even change encryption keys to the content to prevent access by the client. In one embodiment, failure to receive an acknowledgement response from the server of a connection with the client, or from the client, may result in invocation of a revocation failure action. | 11-27-2008 |
| 20090003600 | PROGRESSIVE DOWNLOAD OR STREAMING OF DIGITAL MEDIA SECURELY THROUGH A LOCALIZED CONTAINER AND COMMUNICATION PROTOCOL PROXY - Various embodiments are directed towards employing a container and communication protocol proxy component within a client device to receive securely real-time streamed, progressively downloaded, or adaptively streamed container over a network using one container and communication protocol, and to securely decrypt the container and provide it to a media player using a different container and communications protocol. In one embodiment, the container is in Flash Video (FLV) file format. A browser or the media player on the client device may be used to request the container. The requested container is sent over one communication protocol and intercepted by the container and communication protocol proxy component. The container may be received as selectively encrypted container. The container and communication protocol proxy component then may enable decryption of the container and providing of it to the media player using another container and communication protocol combination. | 01-01-2009 |
| 20090204541 | PREVENTING UNAUTHORIZED MODIFICATION OR SKIPPING OF VIEWING OF ADVERTISEMENTS WITHIN CONTENT - A method, apparatus, and system are directed towards employing a chain of permission keys obtained during playing of advertisements within content to enable continued playing of the content. A sequence of encoded permission keys are generated with each encoded permission key, except a last permission key, incorporating a scrambling key useable to decode a next encoded permission key within the sequence of encoded permission keys that enables playing of a next portion of the content. If playing of any advertisement within the content is avoided, then access to an associated scrambling key useable to decode a next permission key is prevented, which in turn inhibits playing of a next portion of the content. In another embodiment, a heartbeat analysis may also be performed to monitor if skipping of an advertisement is being attempted, and if so, playing of the content is prevented. | 08-13-2009 |

| 20100006057 | Oil seal - According to the present invention, a variable compression ratio machine having main bearings mounted in an eccentric carrier or support includes an oil seal located primarily in a main bearing cap for minimizing leakage of pressurized main bearing oil. The seal is located generally in a first main bearing fastener socket or fastener access cutout in order to minimize structurally compromising the bearing cap, and a portion of the fastener socket preferably is used as an oil passageway as well as for wrench access to the fastener. The oil seal and oil circuit of the present invention enable the size of the eccentric support to be minimized while also providing highly effective oil sealing. In more detail, a significant advantage of the present invention is that highly effective oil sealing is attained without compromising the size or structural integrity of the bearing cap. A second significant advantage of the present invention is that it can be manufactured and assembled at low cost. The oil sealing system of the present invention is robust and highly reliable. | 01-14-2010 |
| 20100133031 | HYDRAULIC HYBRID POWER SYSTEM - According to the present invention a pump is driven by one or more wheels of a hydraulic hybrid vehicle during braking. The inertial energy of the vehicle powers the pump during braking of the vehicle, and the pump pumps a hydraulic liquid into an hydraulic accumulator that stores the fluid at its elevated pressure. When additional power is required by the vehicle, the liquid is released into a heat exchanger that transfers heat from the exhaust gas of the engine to the liquid causing at least a portion of the liquid to become gaseous. The heated fluid is then fed into an expander that generates shaft power by expanding the pressurized and heated gaseous and/or liquid fluid mixture. The preferred embodiment of the present invention operates under the Rankine cycle or steam engine cycle where the liquid compression function is performed using power from regenerative braking, and the liquid heating and vaporization function is performed using exhaust gas waste heat. The present invention shows potential for more than tripling the regenerative braking power of hydraulic hybrid vehicles, thereby providing a large improvement in vehicle fuel economy. | 06-03-2010 |
| 20110033234 | POWER TAKE-OFF COUPLING - According to the present invention, a variable compression ratio engine having crankshaft main bearings mounted in one or more eccentrics includes a power take-off coupling having a single link or linkage. In the preferred embodiment of the present invention a drive arm is integrated into the crankshaft and a driven arm is integrated into the torque converter or clutch housing. The power take-off coupling further has a linkage having a first linkage end and a second linkage end. The first linkage end is pivotally connected to the drive arm and the second linkage end is pivotally connected to the driven arm for transferring torque from the crankshaft to the torque converter or clutch housing. According to the preferred embodiment of the present invention, the power take-off coupling has only one link. The link, drive arm and driven arm are all rigid components made out of steel or other suitably stiff and strong metal. The single link is exceptionally robust, reliable and simple. The axels for the linkage are generally larger in diameter than piston pins, and can withstand engine detonation forces as well as other cranktrain bearings can, such as the piston pins, connecting rod big end bearings and crankshaft main bearings. The power take-off coupling of the present invention has a low cost and is easy to assemble. A further advantage of the present invention is the small magnitude of its friction penalty. Engines that are currently mated to torque converters will require only one new bearing to support the output shaft of the present invention. The one new bearing contributes relatively little to over-all engine friction losses. The linkage axel bearings pivot only a few degrees back and forth, and do not substantively increase engine friction losses. Another advantage of the present invention is its short axial length. The short axial length is highly desirable for packaging of the variable compression ratio engine in the small engine bays commonly found in passenger cars. The power take-off coupling of the present invention is robust and reliable, can withstand detonation forces to the same degree as other cranktrain components, has very low friction losses, has a short axial length, is easy to assemble, and has a low cost . | 02-10-2011 |
