  • Publication number: 20230274361
    Abstract: Improvements in distributed ledger technology for capturing, maintaining and updating data for asset-backed securitizations are described. The invention provides a distributed ledger platform which automates the capture of specified data regarding the underlying financial assets, including owners, trustees, servicers and other parties associated with asset-backed securitizations, and stores and maintains the data in a blockchain to provide users with a secure, reliable, immutable and distributed ledger of the data and to generate custom data reports of information stored in the ledger. An offchain database may be maintained in synchrony with the blockchain to allow for reduced computational load. The invention also provides a mechanism for managing changes in the data using a smart contract based consensus mechanism, for example, to record securitization party replacements in an automated manner.

  • Publication number: 20220248104
    Abstract: Aspects of the subject disclosure may include, for example, identifying unselected video content items and preconfiguring playback views for unselected video content items. During a warm-up phase, access to the unselected video content items is precoordinated individually with a separate video player, manifests and license/key are retrieved in anticipation for possible selection for playback. Subsequent selection of one of the unselected video content items initiates playback responsive to selection without repeating any of the preconfiguring, preauthorizing or fetching. Other embodiments are disclosed.

  • Patent number: 10015910
    Abstract: A heat pipe includes a binary working fluid including a composition proximate to and less than or equal to the azeotropic point in a thermodynamic phase diagram as a function of the composition of the binary working fluid. Moreover, in a liquid phase of the binary working fluid, a boiling point of the binary working fluid as a function of temperature and the composition in the thermodynamic phase diagram is approximately constant. For example, the boiling point may vary by less than a degree Celsius over a range of compositions proximate to and less than or equal to the azeotropic point. Furthermore, components in the binary working fluid may be fully miscible as a function of the temperature and the composition in the thermodynamic phase diagram, a component in the binary working fluid may include a non-zero dipole moment, and/or the component may form a hydrogen bond with water.

  • Patent number: 7359313
    Abstract: A system employs space-time coding characterized at the transmitter by bit-interleaved coded modulation (BICM) combined with multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) modulation. Space-Time coding techniques improve transmission efficiency in radio channels by using multiple transmit and/or receive antennas and coordination of the signaling over these antennas. Bit-interleaved coded modulation provides good diversity gain with higher-order modulation schemes that employ binary convolutional codes. OFDM modulation allows for wideband transmission over frequency selective radio channels. A receiver demodulates the OFDM signal and applies multi-input, multi-output (MIMO) demapping to estimate the BICM encoded bitstream. After deinterleaving of the BICM encoded bitstream, maximum a posteriori (MAP) decoding is applied to the resulting bit stream to generate soft output values.

  • Publication number: 20070225497
    Abstract: The present invention provides bipyrimidinyl diphosphine compounds of the formula wherein R is optionally substituted alkyl, cycloalkyl, aryl or heteroaryl; R? and R? are independently optionally substituted alkyl, cycloalkyl, aryl or heteroaryl; or an enantiomer thereof; or an enantiomeric mixture thereof. The compounds of the formula (I) are chiral atropisomeric bipyrimidinyl diphosphine compounds and, thus, may be employed as ligands to generate chiral transition metal catalysts which may be applied in a variety of asymmetric reactions, e.g., in palladium catalyzed asymmetric allylic substitution reactions. The compounds of the present invention are easily accessible in high enantiomeric purity according to the methods disclosed herein.

  • Patent number: 7095812
    Abstract: A system employs space-time coding characterized at the transmitter by bit-interleaved coded modulation (BICM) combined with modulating several streams of the BICM encoded data for transmission over two or more antennas. Space-time coding techniques improve transmission efficiency in radio channels by using multiple transmit and/or receive antennas and coordination of the signaling over these antennas. Bit-interleaved coded modulation provides good diversity gain with higher-order modulation schemes that employ binary convolutional codes. A receiver demodulates the received signals and applies multi-input, multi-output (MIMO) demapping to estimate the BICM encoded bitstream. After deinterleaving of the BICM encoded bitstream, maximum a posteriori (MAP) decoding is applied to the resulting bit stream to generate soft output values. By applying well-known turbo-decoding principles to iteratively demap and decode, the overall receiver performance is significantly improved.

  • Patent number: 6948999
    Abstract: A “magic mirror” wand toy has a body having a mirror element that is partially transparent. An image illuminating apparatus is mounted rearward of the mirror element. An image transport apparatus has a plurality of images that can be positioned selectively and alternately in front of the illuminating apparatus. When an image is stationary, it is lit up and an audible message associated with the image may be played. The wand can be operated in sampling mode, in which each of the set of images is displayed in sequence, and in an individual selection mode.
