  • Publication number: 20100137597
    Abstract: This application discloses a novel process for the preparation of phosphonate esters useful as intermediates in the preparation of himbacine analogs, themselves useful as thrombin receptor antagonists. The chemistry taught herein can be exemplified by the following scheme: wherein R9 is selected from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms, and R11 is selected independently for each occurrence from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms and hydrogen, X2 is Cl, Br, or I; X3 is selected from Cl and Br; and PdLn is a supported palladium metal catalyst or a soluble heterogeneous palladium catalyst. The L-derivatizing reagent is a moiety which converts the alcohol functional group of compound 137D to any leaving group which can be displaced by a triorgano-phosphite phosphonating agent.

  • Publication number: 20100131719
    Abstract: A data processing system is described that reduces read latency of requested memory data, thereby resulting in improved system performance. An exemplary system includes a bus, a processor, and a controller associated with the processor. The controller is configured to send a request for data to a memory storage unit, receive, from the memory storage unit, an early response indicating that the controller will later receive the requested data, and upon receipt of the early response indicator, start a timer to wait a period of time. The controller is further configured to, after expiration of the timer but prior to receipt of the requested data, send an arbitration request to initiate a transaction on the bus to communicate the requested data from the controller to the processor when the requested data is later received by the controller.

  • Patent number: 7721389
    Abstract: An internal hinge (34) for a fire-resistant enclosure is provided. The internal hinge includes a cabinet end (36) and a door end (38). The cabinet end is pivotally coupled with a bracket (64) mounted on the enclosure and the door end is fixedly coupled with a door (32) of the enclosure. The hinge includes first, second, third, and fourth segments (72, 74, 76, 78). The first segment extends linearly from the cabinet end of the hinge. The second segment extends from the first segment in a generally curved path wrapping around the cabinet end approximately 90 degrees. The third segment extends linearly from the second segment and at an angle relative to the first segment. The fourth segment extends linearly from the third segment to the door end of the hinge and is perpendicular to the first segment. The internal hinge of the present invention allows the door of the enclosure to open approximately 147 degrees.

  • Patent number: 7699966
    Abstract: Methods and devices for point of care determination of heparin concentration in blood are described. Cartridges including protamine ion sensitive electrodes (ISEs) and reference electrodes and systems for automatically determining heparin concentration in the cartridges are provided. Some systems add blood to a protamine bolus sufficient to bind all heparin, leaving excess protamine. The excess protamine concentration can be determined by measuring the initial slope of the electrode potential rate of change, and comparing the slope to known protamine concentration slope values In some cartridges, an oscillating pressure source moves the blood-protamine mixture back and forth across the protamine ISE. Some systems also use a second blood sample having the heparin removed or degraded to create a blank reference sample. Protamine ISEs can include polyurethane polymer, DNNS ionophore, and NPOE plasticizer.

  • Patent number: 7695471
    Abstract: The present invention relates to a bone fixation device having a fixation member using a shape memory effect to secure bone fractures, including but not limited to, femur, tibia and humerus fractures. The fixation member can be malleable at a room temperature, but become rigid at a body temperature because of the shape memory effect, such as derived from a super-elastic property found in such as a nickel titanium alloy. The fixation member can be formed on one or more of the shaft portion and the two end portions of a nail member for securing bone fractures, such as by providing translational and rotational stabilities. The fixation member is also capable of providing a continuous and controllable compression force over the fractured bone, if needed.

  • Publication number: 20100057327
    Abstract: A system and method for operating an engine having at least two spark plugs per cylinder include controlling at least one actuator to alter combustion within a selected cylinder such that the combustion burn rate determined by ion sense current signals associated with the at least two spark plugs of the selected cylinder approaches a desired combustion burn rate. A desired combustion burn rate is determined based on current engine/vehicle operating and ambient conditions with ion sense signals from each spark plug analyzed to determine combustion timing relative to corresponding ignition timing. Ignition timing and/or other actuators are controlled in response to provide a desired combustion burn rate.
