A device client operates on the communications device and initiates a request to the internet service that authenticates the user and establishes a secure communications channel between the internet service and communications device and determines key generation parameters based on an authenticated user identifier and transmits the key generation parameters for initiating key generation and securely establishing a cryptographic key between the internet service and communications device.

Abstract: The present invention relates to the field of antennas and specifically to broadband antennas. Planar low-profile antennas over high-impedance surfaces show improved performance compared to that over metal ground planes, but these high-impedance surfaces often operate over narrow bandwidths because current approaches to the design of high-impedance substrates typically employ identical unit cells with the same resonant frequency to produce high-impedance behavior over a relatively narrow frequency range. The present invention provides improved antenna performance over a broader bandwidth through the use of electromagnetic bandgap cells having a size and related resonant frequency that varies with position to the antenna radiating element in order to match the resonance of the element.

Abstract: The present invention is a sports bottle ball, which is a baby bottle holder with the shape and the appearance of a sports ball. In the preferred embodiment, the material composition of the invention is an infant-safe, soft-foamed, non-liquid absorbing, non-toxic, closed-cell synthetic material suitable for infants to touch and hold. The invention has a cavity and a removable sleeve. The removable sleeve is positioned within the cavity. Both the removable sleeve and the cavity allow the invention to accommodate common baby bottle sizes. Specifically, the removable sleeve is to accommodate a smaller diameter whereas the cavity is to accommodate a larger diameter. Furthermore, the outer layer of the foam sports ball comprises a plurality of small protrusions which provide friction to the surface of the foam sports ball. The friction upon the surface of the foam sports ball helps the newborn to grip the invention with more ease.

Abstract: This invention relates to a perforated cover which is retrofitted to a slicing machine for meat and other foods. The perforated cover may be made from metal and non-metal materials. The perforated cover is designed to be removed from the slicing machine so that the perforated cover and slicing machine can be cleaned. The perforated cover acts as a protective shield for the operator's hands and fingers while the operator is using the slicing machine. The perforated cover is attached to the slicing machine and moves with the slicing machine thus allowing the operator to use the slicing machine while the perforated cover is in place. Technology has evolved where a cutting system can accurately insert perforations in materials during manufacture which allows the operator to see through the perforated cover while the slicing machine is being operated. In addition the perforations reduce the weight of the perforated cover which makes the perforated cover easier to remove and carried by humans.

Abstract: Data and metadata are generated in a computational device, wherein the generated data is stored in a first physical storage device coupled to the computational device, and wherein the generated metadata is stored transiently in the computational device. The data and the metadata are replicated to a second physical storage device. The replicated data and the replicated metadata in the second physical storage device are used to recover from a failure of at least one of the computational device and the first physical storage device.

Abstract: One aspect of the invention concerns a launder assembly (10) for conveying molten material from a metallurgical furnace, The assembly is made up of launder sections (12) arranged end to end with connections between adjacent ends of the launder sections. Each launder section includes a base (14) and spaced apart side walls (16, 18). At each connection between the adjacent ends of two launder sections, the bases of the launder sections are formed with recesses (28) which, in combination, form a cavity (32). A connector (34) is located in the cavity and in that the bases of the launder sections are connected to one another through the connector. In the preferred arrangement, the bases of the launder sections are connected to the connector by fasteners, typically bolts (38) which engage the bases and in threaded holes (42) in the connector.

Abstract: Control of gas turbine speed and acceleration during unloaded rotation may limit stresses on components and facilitate timely operational performance. Operation of a torque converter driving a gas turbine shaft from a starter motor provides control over acceleration and speed of the gas turbine shaft. Hydraulic coupling between the input and output of the torque converter is adjusted by draining and refilling the working fluid in a body of the torque converter to control acceleration and speed of the rotor shaft during a first speed range. Vane positioning within the torque converter may be alternated between discrete speed settings to control acceleration and speed of the rotor shaft during a second speed range. A turbine control system with an acceleration schedule may provide control signals for these functions.

Abstract: A continuous heat set line for setting yarn, having spaced-apart, elongate, tubular entrance and exit cooling chambers interconnected by an elongate intermediate steam heat-setting chamber communicating therewith. The entrance and exit cooling chambers and the intermediate heat-setting chamber collectively define a single longitudinally-extending axis along the combined length thereof. Sealing heads seal the entrance and exit cooling chambers and the intermediate heat-setting chamber to a degree sufficient to maintain a pressurized condition within the heat-setting chamber. A yarn conveyor extends through the pretreatment chamber for conveying the yarn through the entrance and exit cooling chambers and the heat-setting chamber. At least one piston and cylinder assembly moves sealing rolls into and out of position relative to each other, while independently-operating springs urge the rolls together sufficiently to effect a seal.
