  • Patent number: 7424907
    Abstract: An integrated fan pump includes a fan, a pump, and an electrical drive mechanism such as an electric motor configured to simultaneously drive both the fan and pump with respect to the housing. A heat exchanger is preferably connected to the pump and the component to be cooled. In one embodiment, the fan head and the pump head are fixed to a common axle, a single magnet is fixed to the fan head, and the magnetic coil is fixed to the housing. In another embodiment, the fan head and pump head rotate about a fixed axle, the magnetic coil is fixed to said housing, one magnet is fixed to the fan head, and a second magnet is fixed to the pump head.

  • Publication number: 20070066950
    Abstract: An at least partially elastic ear for use on a disposable diaper is provided. The at least partially elastic ear is rectangular in shape, the rectangular shape formed by a top edge, a bottom edge, a distal edge between the top edge and bottom edge proximate to at least one fastener, and a proximal edge between the top edge and bottom edge distal to the at least one fastener. Further, a disposable absorbent garment, such as a diaper, is provided with a pair of rectangular at least partially elastic ears.

  • Patent number: 7191820
    Abstract: A heat transfer system is presented for managing thermal transients, thus providing engineers greater flexibility in designing thermal solutions for applications subject to transient heat-generation. A heat reservoir device for managing a heat input subject to transient conditions includes a heat transfer subsystem having a first end and a second end, where the first end is thermally coupled to the heat input; a heat storage subsystem coupled to the second end of the heat transfer subsystem, where the heat storage subsystem comprises a phase change material responsive to the transient conditions. The excess heat load during transient operation is temporarily absorbed by the latent heat of fusion when the phase change material changes its phase from solid to liquid. Subsequently, the absorbed heat can be released back to the ambient via a heat rejection subsystem. This allows engineers to design smaller heat sinks capable of accommodating given transient conditions.

  • Publication number: 20060272006
    Abstract: A method of processing electronic data includes receiving electronic data, and scanning at least a portion of the electronic data against a first signature, wherein the first signature is not data-type dependent. A method of processing electronic data includes receiving electronic data to be scanned, identifying a portion of the electronic data, wherein the portion is represented as an object, and assigning one or more procedures to scan the portion based at least in part on the object. A system for processing electronic data includes an input for receiving electronic data, a processor configured for identifying one or more portions of the electronic data, each of the one or more portions represented as a typed object, and a buffer configured to store data associated with no more than one object at a time.
