  • Patent number: 9773526
    Abstract: A system for cooling hard disk drives (HDDs) includes: an enclosure having (i) a lower volume within which a cooling liquid is heated to a boiling point to cause some of the cooling liquid to evaporate, creating a plume of rising vapor and (ii) an upper volume having (a) a HDD cooling area with HDD(s) placed in the direct path of the rising vapor, which cools the HDD(s) during functional operation of the HDD(s) and (b) a condenser located above the HDD cooling area and which cools a substantial portion of the rising vapor that impacts the condenser within the upper volume such that the rising vapor condenses back into liquid phase on contact with the condenser; and a heat source that dissipates heat into the lower volume of the enclosure, sufficient to heat the cooling liquid to the boiling point temperature.

  • Patent number: 9754398
    Abstract: Techniques are described by which the data associated with a 3D animation may be reduced in a manner that does not result in perceptible visual artifacts when the animation is rendered on the display of a target device. Animation curve reduction is achieved by the removal of redundant animation curve samples, and is independently guided for different object attributes or animation channels by the nature of the attribute and one or more display parameters of the target device for which the animation is intended.

  • Patent number: 9716537
    Abstract: Techniques for performing automatic antenna sector-level sweep switching are described herein. According to an embodiment, an apparatus comprises a lookup table for storing a set of antenna configuration entries and a sector-level sweep (SLS) controller implemented in hardware that is communicatively coupled to the lookup table. The SLS sweep controller is operative to read an antenna configuration entry from the set of antenna configuration entries stored in the lookup table and output control signals to configure a set of one or more antennas based on the antenna configuration entry. The SLS controller is further operative to switch between different antenna configuration entries in the set of antenna configuration entries stored in the lookup table in response to a signal from a timing source thereby periodically changing the configuration of the set of one or more antennas.

  • Patent number: 9701911
    Abstract: A method for producing a light oil fraction from plant-based and/or animal-based fats, oils or greases is disclosed. The method comprises introducing a feedstock including free fatty acids into a processing system. The system is heated at a controlled rate to a specified temperature, both of which are selected to produce a light oil fraction with a reduced fatty acid content. The system is permitted to reflux for a predetermined time, during which more of the light oil fraction is produced. The light oil fraction is separated from the remainder of the feedstock and contains less than 10% free fatty acids.

  • Patent number: 9485133
    Abstract: DCMI functionality is extended to platforms of a datacenter by integrating a management controller in each of plural platforms and interfacing the management controllers with a management server through a network. End users interface with platforms of the datacenter using DCMI protocol communications. The management server supports communication with management controllers by receiving DCMI messages and translating the DCMI messages to a text-based protocol for communications with the management controllers. In one embodiment, the management controllers push sensor information for their associated platforms to a sensor cache of the management server so that the management sensor references the cache to respond to DCMI requests for sensor information.
