Patent number: 10812648Abstract: A device includes a context engine and a notification engine. The context engine determines a context indicator relative to received input while the notification engine selects, based on the context indicator and the received input, at least one type of notification from different types of notifications. A wearable electronic arrangement selectively communicates, and senses for different types of single user response to, at least a portion of the received input via the selected type of notification. The context engine receives feedback regarding the sensible different types of single user response to at least partially determine the context indicator.Type: GrantFiled: October 24, 2016Date of Patent: October 20, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Michael W.

Patent number: 8848536Abstract: Stateless load balancing of network packets within a system avoids detection by a network client or end user for deep packet inspection or other bump-in-the-wire applications. At least one header field of a received packet is used in generating a hash value. The hash value is used to identify a processing resource within the system for processing the received packet. Before being sent to the identified resource, the received packet is encapsulated with a new header that includes an indication of ingress port. The encapsulation does not modify the original packet. On a return path from the identified processing resource, the ingress port is determined from the encapsulated packet, the encapsulated packet is decapsulated to obtain a recovered packet that is identical to the received packet, and the recovered packet is forwarded to the network through an egress port as determined from the recovered ingress port.Type: GrantFiled: August 30, 2013Date of Patent: September 30, 2014Assignee: RadiSys CorporationInventors: Michael W. Hu, Andrew P. Alleman

Patent number: 8711681Abstract: Backplane redundancy is provided for a system including multiple nodes that communicate packets through first and second switches. Assuming that the first switch is initially assigned to an active state and the second switch to a standby state, the nodes communicate the data packets through physically enabled first backplane links to the first switch. The nodes physically enable second backplane links that are in a condition to communicate the data packets to the second switch. A messageless failover process is initiated by temporarily disabling, at the first switch, the first backplane links between the first switch and the nodes. In response to the nodes detecting the disabled first backplane links to the first switch, the nodes reconfigure themselves to communicate the data packets through the second backplane links to the second switch and to stop communicating the packets through the first backplane links to the first switch.Type: GrantFiled: February 8, 2012Date of Patent: April 29, 2014Assignee: Radisys CorporationInventors: Michael W.
