  • Publication number: 20120017213
    Abstract: The disclosed architecture facilitates the sandboxing of applications by taking core operating system components that normally run in the operating system kernel or otherwise outside the application process and on which a sandboxed application depends on to run, and converting these core operating components to run within the application process. The architecture takes the abstractions already provided by the host operating system and converts these abstractions for use by the sandbox environment. More specifically, new operating system APIs (application program interfaces) are created that include only the basic computation services, thus, separating the basic services from rich application APIs. The code providing the rich application APIs is copied out of the operating system and into the application environment—the application process.

  • Publication number: 20080200531
    Abstract: The invention provides new methods for inhibiting the CDKI pathway and specifically inhibiting tumor cell growth. The invention further provides new and specific inhibitors of tumor cell growth, as well as means for discovery of additional such inhibitors. The present inventors have surprisingly discovered that Cyclin-Dependent Kinase 3 (CDK3) is specifically required for tumor cell growth, in contrast to other members of the CDK family.

  • Publication number: 20080060373
    Abstract: An isolation valve assembly, a coolant connect/disconnect assembly, a cooled multi-blade electronics center, and methods of fabrication thereof are provided employing an isolation valve and actuation mechanism. The isolation valve is disposed within at least one of a coolant supply or return line providing liquid coolant to the electronics subsystem. The actuation member is coupled to the isolation valve to automatically translate a linear motion, resulting from insertion of the electronics subsystem into the operational position within the electronics housing, into a rotational motion to open the isolation valve and allow coolant to pass. The actuation mechanism, which operates to automatically close the isolation valve when the liquid cooled electronics subsystem is withdrawn from the operational position, can be employed in combination with a compression valve coupling, with one fitting of the compression valve coupling being disposed serially in fluid communication with the isolation valve.

  • Publication number: 20070044493
    Abstract: Systems and Methods of cooling heat generating electronics components are provided employing vapor compression refrigeration. In one embodiment, the vapor compression refrigeration system includes a condenser, at least one expansion structure, at least one evaporator, and a compressor coupled in fluid communication to define a refrigerant flow path, and allow the flow of refrigerant therethrough. The at least one evaporator is coupled to the at least one heat generating electronics component to facilitate removal of heat produced by the electronics component. At least a portion of the at least one expansion structure is coated with a polytetrafluorethylene in the refrigerant flow path for inhibiting accumulation of material thereon. The polytetrafluorethylene coating has a thickness sufficient to inhibit accumulation of material in a pressure drop area of the expansion structure without significantly changing a pressure drop characteristic of the pressure drop area.

  • Patent number: 6320750
    Abstract: A line replaceable module (LRM) configured with a plurality of mini-modules, each of which have relatively higher contact densities than currently available LRMs with the same form factor, for example, a Standard Electrical Module-Size E (SEM-E) form factor. The mini-modules are significantly less expensive than an entire module allowing such mini-modules to be disposable, eliminating relatively costly fault diagnostics and repair. Each mini-module includes a printed circuit board which includes a rigid primary portion, a rigid secondary portion and flexible portion interconnecting the primary and secondary portions. The rigid secondary portion may be configured to provide dual-sided interconnection to a backplane data bus. Use of the dual-sided rigid secondary portion provides for generous spacing for contact densities much higher than known contact densities for LRMs with the same form factor. The rigid primary portion carries the components forming the LRM.

  • Patent number: 5602876
    Abstract: In an RF receiver a system is provided to digitally determine when a pulse has stabilized and when a pulse has restabilized after becoming unstable. The restabilized levels can be detected whether they are above or below the initial stabilization level. The system uses the stable information to determine if a pulse-on-pulse signal is being received or if a trailing edge pulse is being received. The system can provide separate information about each pulse in a pulse-on-pulse situation and can provide separate information concerning the leading pulse and trailing pulse when the trailing pulse occurs in the shadow of the leading pulse.

  • Patent number: 5572213
    Abstract: A channelized receiver having multiple sectors wherein each antenna of said receiver system is electronically connectable to any combination of sectors to improve the flexibility of said receiver. The bandwidth of each sector is electronically selectable adding further flexibility to the receiver mission. The signal characteristics of time of arrival, pulse amplitude and time of departure are processed digitally in real time and false pulses are eliminated through arbitration in real time. Remaining pulse calculations such as angle of arrival, frequency, pulse width and pulse repetition interval and environment filtering are not calculated in real time.

  • Patent number: 5550546
    Abstract: In a channelized receiver there is dual pulse present detection in which an RF signal is converted to a digital word and there are dual digital thresholds, each digital threshold having a programmable standard for determining when a pulse is present after said pulse has exceeded the particular threshold value and for determining which pulse will be reported based on which pulse arrived first. The invention also involves arbitration between adjacent channels in a channelized receiver to determine which signals are real and which signals represent spill-over energy from signals in adjacent channels and also including arbitration between spatial sectors to determine which signals are real and which signal represents spill-over energy from adjacent sectors.

  • Patent number: 3991710
    Abstract: A coating system for efficient electrical precipitation of powder to articles. Articles are conveyed through a coating chamber where they are coated with a powder. Electrogasdynamic guns direct a cloud of charged particles into the coating chamber. Dilution air moves the cloud through the chamber with the articles. As the cloud moves with the articles, the charged particles precipitate to the articles. An exhaust section draws off the dilution air as the coated articles leave the chamber. Electrically conductive articles may be grounded through the conveyor system to provide a discharge path from the charged particles. For nonconducting or hard to ground articles, a precharge section places on the articles an initial charge of opposite polarity from the charged particles. A powder feed using a cylinder and piston arrangement to contain fluidized powder supplies a uniform powder suspension to the guns.
