  • Publication number: 20160346782
    Abstract: An integrated microfluidic device for carrying out a series of fluidic operations includes a housing including a plurality of n microfluidic conduits, wherein n is at least three, and a rotating valve having an internal channel with an entrance port and an exit port that are angularly separated. The rotating valve is positionable in a first position to connect two of the n fluidic conduits via the internal channel, and upon rotating the valve to a second position, two other of the n fluidic conduits are connected by the internal channel. The device further may include one or more fluidic chambers in fluid communication with respective fluidic conduits. Fluid contained in one fluidic chamber is transferrable by application of positive or negative gas pressure through associated fluidic conduits into another fluidic chamber via the internal channel. The device may be utilized to perform a variety of fluidic operations.

  • Patent number: 8468191
    Abstract: Systems and methods for multi-precision computation are disclosed. One embodiment of the present invention includes a plurality of multiply-add units (MADDs) configured to perform one or more single precision operations and an arrangement generator to generate one or more mantissa arrangements using a plurality of double precision numbers. Each MADD is configured to receive and load said mantissa arrangements from the arrangement generator. The MADDs compute a result of a multi-precision computation using the mantissa arrangements. In an embodiment, the MADDs are configured to simultaneously perform operations that include, single precision operations, double-precision additions and double-precision multiply and additions.

  • Patent number: 8151135
    Abstract: Systems and methods for reducing problems and disadvantages associated with traditional approaches to data and program storage on an information handling system are provided. A method may include determining if a primary storage resource has a failure. The method may further include, in response to determining that the storage resource does not have a failure: booting from a first operating system stored on the primary storage resource, monitoring data stored to the primary storage resource to identify data to be copied to a persistent storage resource, and copying the identified data to the persistent storage resource. The method may further include, in response to determining that the storage resource has a failure: booting from a second operating system stored on the persistent storage resource, and via the second operating system, providing access to the copied identified data copied to the persistent storage resource.

  • Patent number: 7523321
    Abstract: An information handling system (IHS) includes a system board including a processor, a first battery for supplying power to the system board, a second battery for supplying power to the system board, and a switching circuit. The switching circuit is configured to repeatedly switch between the first battery and the second battery for supplying power to the system board to provide more power to the IHS than is possible if only one battery were continuously providing power to the IHS.

  • Patent number: 6550575
    Abstract: A combination apparatus for vehicles with or without an open bed comprising an elevated viewing perch or observation stand with a seat, a luggage/personnel carrier/kayak carrier, a pontoon boat, a fishing platform, and a farm plow. The viewing perch can be mounted on an open bed vehicle such as ATV's, trucks or the like vehicles and have a ladder-type frame on rear wheels. The frame can be used as a utility trailer for hauling equipment, game or an injured person, and readily converted to an elevated position and used as a viewing or hunting stand. The apparatus can be raised to the elevated position by hand or by a winch, can serve as a tent shelter with bunk-type cots placed inside, and can be wired for lighting, energized by the vehicle's battery.
