摘要: 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.

摘要: An economy class cabin with sleeping berths in a passenger aircraft, includes cabin floor, multi-tier sleeping berths, an air duct, an overhead bin, seats, a baggage storage place, a shoe storage place and multi-tier baggage racks. The multi-tier sleeping berths are disposed in parallel to longitudinal axis of the aircraft; a longitudinal partition board is disposed between two abreast sleeping berths; and two latitudinal partition boards are respectively disposed at two opposite ends of each of the sleeping berths and a private space is formed by the longitudinal partition board, two latitudinal partition boards, a bed cushion and a slidable curtain. The present invention has simple structure and reasonable utilization of compact space, enables all or some of passengers of the economy class to be in a lie-flat sleeping state in half of the time in intercontinental flight.

摘要: A reputation system aids in the prevention of unwanted spam or malicious communications from being sent to a mobile device, such as a cell phone. A collaborative process is used to determine ratings for a collection of source identifications of the communications. The source identifications are caller identifications (IDs) of a corresponding voice or SMS communication. A collection of opinions is maintained regarding the caller IDs. The reputation system then uses a method of making automatic predictions about the caller IDs by collecting caller ID information from many users to populate the database of maintained opinions. As such, caller IDs of users who have sent spam or malicious messages can be blocked by using collaborative information from many users, as opposed to relying on individual users to block unwanted communications.

摘要: In one embodiment, a method of forming a multi-channel power supply controller includes forming a plurality of channels configured to regulate an output voltage between first and second values, configuring the controller to select a channel that has a lowest current value and initiate forming a drive signal for that channel responsively to the output voltage having a value that is less than the first value, configuring a reset circuit for each channel to terminate the respective drive signal responsively to at least the output voltage having a value greater than the first value.
