  • Patent number: 8708273
    Abstract: A vertical takeoff and landing aircraft having a fuselage with, preferably, three wings and six synchronously tilt-able propulsion units, each one mounted above, below, or on each half of the aforementioned three wings. The propulsion units are oriented vertically for vertical flight and horizontally for forward flight. Each propulsion unit comprises a propeller having a plurality of blades, where the pitch angle associated with the distal end of each blade and the proximal end of each blade are independently adjustable. As such, each of the propellers can be adjusted to exhibit a first blade pitch angle distribution optimized for vertical flight and a second blade pitch angle distribution optimized for forward flight.

  • Patent number: 8713451
    Abstract: Methods for delivering rich media content to a user within an email system via a dedicated media channel. An email system receives an email message associated with rich media content from a registered sender for delivery to a recipient. To improve the recipient's viewing experience, the email system ensures that the rich media content is loaded in a rich media database before delivering the email message to the recipient. When the recipient reads the email message, the email system delivers the rich media content to the recipient from the rich media database via a dedicated media channel efficiently and at a low cost.

  • Patent number: 8710214
    Abstract: The present invention relates to cellulose esters having low hydroxyl content for use in optical applications, such as liquid crystal display (LCD) films. Films made with low hydroxyl levels and a given ratio of non-acetyl ester to hydroxyl level have been found to have low intrinsic birefringence. These films can be cast, molded, or otherwise oriented without an appreciable birefringence or optical distortion (i.e. retardation). Such features make these films useful in polarizer, protective, and compensator films as well as molded optical parts, such as lenses. Furthermore, it has also been found that resins of the present invention can also be made to have “+C plate” behavior either by melt or solvent based processing, a characteristic which is not typical of cellulose esters. Such +C behavior allows films to be produced having unique compensatory behavior. Other embodiments of the invention relate to methods melt casting films while minimizing birefringence formation.

  • Patent number: 8712216
    Abstract: Videos are received and indexed based on fingerprints generated for the videos, using lookup keys which correspond to sub portions of the reference fingerprints. Specifically, a set of lookup keys is selected such that the number of reference fingerprints such that the clumping associated with the associated each of the lookup keys is minimized. Clumping occurs when a number of reference identifiers associated with a lookup key exceeds a maximum value.

  • Patent number: 8713106
    Abstract: In some embodiments, the disclosed systems and methods provide a client-server infrastructure capable of supporting a variety of asynchronous and synchronous collaboration activities in a so-called collaboration place. Some of these activities include chatting, viewing and/or editing one or more data files, and sharing one or more applications, data files, and/or displays. The client-server infrastructure supports seamless navigation between the supported asynchronous and synchronous activities in the collaboration place. Additionally, the client-server architecture supports data persistence, so that data files associated with the collaboration place can be stored for subsequent access.

  • Patent number: 8711854
    Abstract: An upstream error controller monitors a media stream at a location upstream from an associated set of receivers receiving the media stream. The upstream error controller sends out suppression notices for any media packets lost upstream causing the receivers to suppress sending lost packet notices. In another embodiment, a repair point joins a primary multicast group with multiple receivers for receiving a native media stream. The repair point also joins a second multicast group receiving multicast backup data for retransmitting or repairing the native media stream that does not include an associated set of receivers. In yet another embodiment, the upstream error controller is used in combination with a hybrid packet repair scheme for adaptively switching among unicast retransmission, multicast retransmission, and Forward Error Correction (FEC).

  • Patent number: 8712826
    Abstract: A method of evaluating the effectiveness of an organization. The method includes participants generating responses to a set of organizational statements as part of a one-day event. The participants are able to interact with each other during various phases of the one-day event in order to generate responses. The responses are entered into a software program running on a computer-based platform, and the software program operates on the responses to generate output results (evaluation results . . . e.g., scores associated with various organizational categories) as part of the one-day event. The results may be used to measure and benchmark effectiveness of the organization and to formulate suggestions and actions to be taken by the organization to improve the effectiveness of the organization.
