Abstract: A computerized method distributes data to devices associated with a local gateway using data distribution rules. Device data that identifies a first device and a second device of a local gateway is obtained and it is determined that the first device is a higher priority device using that device data. A data distribution rule is determined that prioritizes distribution of response data to the first device and that data distribution rule is assigned to a data plan profile associated with the local gateway. A first data request is received from the first device and a second data request is received from the second device. Response data is sent to the local gateway according to the data distribution rule, wherein response data to the first data request sent to the first device via the local gateway is prioritized over response data to the second data request sent to the second device.

Abstract: Methods for forming a single crystal silicon ingot with reduced crucible erosion are disclosed. Solid-phase quartz is added to the melt to reduce erosion at the crucible-melt surface interface. The quartz may be synthetic quartz such as synthetic quartz rods. The quartz may be disposed near the crucible-melt surface interface. Quartz dissolves and suppresses the amount of quartz that dissolves from the crucible at the crucible-melt surface interface.

Abstract: A method of selective pre-caching content fragments is disclosed. The method comprises receiving and analyzing, by an analytics engine, environment data pertaining to a wireless communication device and, based on the analyzing and based on a media presentation response, determining, by a pre-cache manager, an amount of fragments to provide to the wireless communication device for pre-caching to enable playback of the content at a certain quality. The method also comprises selecting, by the pre-cache manager, a subset of fragments of the content based on the determined amount of fragments and sending, by the computer system, the subset of fragments to the wireless communication device. The wireless communication device pre-caches the subset of fragments and presents the content using the cached subset of fragments and remaining fragments received from a content delivery network. The method further comprises receiving, by the analytics engine, playback data from the content delivery network.

Abstract: A surgical retractor and configured to minimize tearing of the gloves without compromising the ability to grip tissue. The surgical retractor has a handle, a blade, and a plurality of retraction elements. The retraction elements may be fixed to the blade but arranged in a specific configuration that a minimizes tearing of the gloves without compromising the ability to grip tissue. The retraction elements may also be made deployable by having a deployed configuration in which the retraction elements are exposed, and a stowed configuration in which the retraction elements are hidden.

Abstract: A method for producing a single crystal silicon ingot from a silicon melt includes providing a crucible within an inner chamber of an ingot puller, the crucible including an inner surface and a synthetic liner on the inner surface. The method further includes adding an initial charge of polysilicon to the crucible, melting the initial charge of polysilicon to cause the silicon melt to form in the crucible, and dissolving a melt modifier into the silicon melt to devitrify the synthetic liner and form a crystallized layer on the crucible. The crystallized layer has a thickness less than 700 microns. The method further includes pulling a single crystal silicon ingot from the silicon melt.

Abstract: A measurement system includes a target object at least partially visible through an opening in a crystal puller. The crystal puller has a silicon melt in a crucible and a reflector defining a central passage through which a crystal is pulled. A detector array captures light through the opening. The detector array is directed to a surface of the silicon melt in the crystal puller and to the target object, and a laser selectively transmits a coherent light beam through the opening to the target object to produce a reflection of the target object on the surface of the silicon melt. An optical modulator pulses the coherent light beams of the laser into discrete coherent light beams having a period, and a lock-in amplifier is connected to the detector array to filter discrete coherent light having the period from captured light.
