  • Patent number: 10693856
    Abstract: Methods and apparatuses are described for automatic authentication switching in online chat sessions. A server receives a request to establish an online chat session from a first client device, including authentication credentials associated with the first client device. The server establishes an online chat session between the first client device and a second client device via a first authenticated communications channel. The server transmits one or more chat messages between the first client device and the second client device using the first authenticated communications channel. The first client device determines that the online chat session has lost authentication. The first client device automatically switches the online chat session to a second unauthenticated communications channel. The server maintains the established online chat session between the first client device and the second client device via the second unauthenticated communications channel.

  • Patent number: 5158143
    Abstract: A lightweight horseshoe particularly suitable for competitive events requiring high maneuverability, the horseshoe including a body having a plurality of sharp ribs extending from the shoe ground engaging face. Four ribs are employed across the shoe body width, the front rib constituting a deeper penetrating grab. The ribs are configured to be self-cleaning, and the shoe includes homogeneous reinforcing bars to resist outward shoe deformation under lateral stress. The reinforcing bars intersect the shoe outer and inner sides, and clearance slots formed in the shoe outer side adjacent the reinforcing bars facilitates the self-cleaning of the shoe adjacent the bars.
