Patent number: 8984139Abstract: A method, at a computing device having one or more processors and memory storing programs for execution by the one or more processors, identifies a conversation including a plurality of participants. A sequence of edits to a content unit in a plurality of content units of the conversation is obtained from a first participant in the plurality of participants to produce a revised content unit. While a second participant of the plurality of participants is providing or editing a portion of the content unit, or viewing the portion of the content unit, the following conditions are imposed. When the second participant is a team member, the conversation is updated for the second participant with the revised content unit by providing the revised content unit to the second participant. When the second participant is a non-team member, updating the conversation for the second participant with the revised content unit is delayed.Type: GrantFiled: April 4, 2014Date of Patent: March 17, 2015Assignee: Google Inc.Inventors: Jens Eilstrup Rasmussen, Lars Eilstrup Rasmussen, Stephen Ma, Alexandre T.

Patent number: 8700776Abstract: A server system hosts a plurality of conversations. For a respective conversation the server system receives units of content from respective participants in the conversation. The server system receives a sequence of edits to a respective content unit of the conversation from at least one participant other than an initial author of the content unit to produce a revised content unit. The server system stores a respective timestamp for each distinct edit in the sequence of edits to the content unit, including distinct timestamps for at least first and second edits to the content unit. The server system updates the conversation with the revised content unit and automatically provides the updated conversation to the one or more server systems hosting conversations for the participants in the conversation.Type: GrantFiled: March 22, 2010Date of Patent: April 15, 2014Assignee: Google Inc.Inventors: Jens Eilstrup Rasmussen, Lars Eilstrup Rasmussen, Stephen Ma, Alexandre T.

Patent number: 7962281Abstract: Digital tile-based mapping techniques are disclosed that enable efficient online serving of aesthetically pleasing maps. In one particular embodiment, an image tile-based digital mapping system is configured for generating map tiles during an offline session, and serving selected sets of those tiles to a client when requested. Also provided are solutions for handling map labels and other such features in a tile-based mapping system, such as when a map label crosses map tile boundaries. Various processing environments (e.g., servers or other computing devices) can be employed in the system.Type: GrantFiled: October 5, 2009Date of Patent: June 14, 2011Assignee: Google Inc.Inventors: Jens Eilstrup Rasmussen, Lars Eilstrup Rasmussen, Stephen Ma

Publication number: 20100241700Abstract: A server system hosts a plurality of conversations. For a respective conversation the server system receives a first sequence of edits and a second sequence of edits to a respective content unit of the conversation from different participants of the conversation. The server system converts the first and second sequences of edits into respective first and second merged sequences of edits. The server system responds to a determination that the first merged sequence of edits and the second merged sequence of edits meet predefined conflict criteria by transforming the first and second merged sequences of edits. The server system sends the respective transformed sequences of edits to respective participants so that respective participants can apply either the first sequence of edits followed by the second transformed sequence of edits or applying the second sequence of edits followed by the first transformed sequence of edits to produce a same result.Type: ApplicationFiled: March 22, 2010Publication date: September 23, 2010Inventors: Jens Eilstrup Rasmussen, Lars Eilstrup Rasmussen, Stephen Ma, Alexandre T.

Patent number: 7616646Abstract: An access server architecture, and methods for use of the architecture to increase the scalability of and balance processor load for a network access server device, are disclosed. In this architecture, packet forwarding and packet processing are distributed amongst cards serving low-speed access lines (i.e., line cards). Thus, as the number of line cards expands, forwarding resources are expanded in at least rough proportion. The NAS route switch controller and the high-speed ports used to access the network are largely relieved of packet processing tasks for traffic passing through the server. The egress port uses a distribution engine that performs the routing lookup for packets received at the high-speed interface, tags the packets with an adjacency table pointer, and sends them to the appropriate forwarding engine for packet processing. The route switch controller, largely uninvolved in the processing of packets, updates routing information needed by each distribution or forwarding engine.Type: GrantFiled: December 12, 2000Date of Patent: November 10, 2009Assignee: Cisco Technology, Inc.Inventors: Stephen Ma, Suresh Sangiah, Jagannadh Tangirala, R.

Patent number: 7606245Abstract: An access server architecture, and methods for use of the architecture, are disclosed. The architecture and methods are designed to increase the scalability of and balance processor load for a network access server device. In this architecture, packet forwarding and packet processing are distributed amongst the cards serving the low-speed access lines, such that each line card is responsible for performing forwarding and packet processing for packets associated with the low-speed ports that line card serves. As the number of line cards expands, forwarding resources are expanded in at least rough proportion. The NAS route switch controller, and the high-speed ports, are largely relieved of packet processing tasks because the egress port uses a distribution engine that performs a cursory examination on one or more header fields on packets received—comprehending only enough information to allow each packet to be distributed to the appropriate line card for full packet processing.Type: GrantFiled: August 18, 2005Date of Patent: October 20, 2009Assignee: Cisco Technology, Inc.Inventors: Stephen Ma, Suresh Sangiah, Jagannadh Tangirala, R.
