Abstract: The present invention relates to a learning game system that comprises a plushy having an internal chamber and a control system that is fitted into the internal chamber. The control system comprises a microcontroller, one or more memory, an impact sensor, and a user interface. During gameplay, a person catching the ball is detected by way of the impact sensor. The person is presented with a question that can be from a variety of school subjects, trivia, or other types of questions. An answer is received from the person by way of the user interface. A determination can be made if the answer is correct or incorrect. The person is prompted to toss the ball to another game-playing person. Game content such as questions can be downloaded, interchanged, or otherwise changed to cover a variety of subject matter areas and be progressively challenging to gameplayers of all ages.

Abstract: Mobile management method, system and client. Method includes receiving a DNS query for a host name from an application on client; retrieving reputation data associated with host name from a local cache on client; and determining a policy based on host name and the reputation data. Based on determined policy for the host name, blocking attempted network flows to a host corresponding to host name to produce blocked attempted network flows. Method also includes sending attempted network flow metadata related to the blocked attempted network flows to a collector on client; transmitting the attempted network flow metadata from the collector to a VPN server pool via a VPN tunnel; and producing an anomaly report from the transmitted attempted network flow metadata. The anomaly report includes at least one of anomalies, cohorts, trends, location boundaries, detected network security issues, detected compromised clients and/or optimized network usage.

Abstract: A downhole apparatus includes a casing string with a fluid barrier connected therein defining a lower end of a buoyancy chamber. A rupture disk is spaced from the fluid barrier and defines an upper end of the buoyancy chamber. A degradable plug is connected in the casing string above the rupture disk. The degradable plug defines a flow path to permit flow therethrough to the rupture disk, and is movable from a first to a second position in the casing string.

Abstract: A system, method, and tool for controlling fluid in a wellbore. The system comprises a tubing string locatable in the wellbore and a crossover tool for enabling reverse circulation in the wellbore. The crossover tool comprises a tool body, a sleeve, a drag block assembly, and a packer assembly. The tool body comprises a bore in fluid communication with the tubing string and a valve in the bore. The sleeve is located in the tool body and controls the valve based on the axial position of the sleeve in the tool body. The drag block assembly is coupled to the sleeve through the tool body and engages the wellbore to resist axial movement of the sleeve relative to the tool body. The packer assembly is coupled to the tool body and creates a fluid barrier in the annulus formed between the tubing string and the wellbore.

Abstract: A downhole apparatus comprises a casing string with a fluid barrier connected in the casing string. A degradable plug is positioned in the casing string above the fluid barrier. The degradable plug and fluid barrier define upper and lower ends of a buoyancy chamber in the casing string. The degradable plug may be degraded to leave an open bore through the casing string after the casing string is lowered into a wellbore.
