Patent number: 11354336Abstract: A configuration for a key management system is provided for managing cryptographic keys in cryptosystems. The configuration includes the use of database replication to improve the reliability, accessibility, and partition tolerance of the key management system. The configuration also includes the use of database sharding and distributed networks to improve the functionality of the key management system. From a logical level, the system can appear multi-master because client software can connect with any compute node in a plurality of compute nodes and perform key management operations on the entire key database from that compute node. From a physical level, the system can be a master-slave configuration with each database shard replication group having a single master shard instance and one or more slave shard instances. In some examples, the present disclosure provides better redundancy, load balancing, availability, and partition tolerance for key management systems.Type: GrantFiled: February 6, 2020Date of Patent: June 7, 2022Assignee: QuintessenceLabs Pty Ltd.Inventors: John Leiseboer, Mayank Daswani, Teresa Bradbury, Florian Poppa, Kenli Chong, John Green, Warren Armstrong, Martin Shannon, Vello Tabur

Patent number: 10671643Abstract: A method, system, and computer-program product for handling network partitions in a network is provided. For example, a method can include providing a first compute node and a second compute node on the network. In such an example, the first compute node can include a master instance of a cryptographic database. In addition, the second compute node can include a first synchronous slave instance associated with the master instance. The method can further include identifying a network partition event on the network. The method can further include providing an asynchronous slave instance associated with the master instance and changing the asynchronous slave instance to a second synchronous slave instance in response to identifying the network partition event.Type: GrantFiled: January 9, 2017Date of Patent: June 2, 2020Assignee: QuintessenceLabs Pty Ltd.Inventors: John Leiseboer, Mayank Daswani, Teresa Bradbury, Florian Poppa, Kenli Chong, John Green, Warren Armstrong, Martin Shannon, Vello Tabur

Publication number: 20120098794Abstract: An apparatus and method for transmitting, collimating and redirecting light from a point-like source to produce a collimated optical signal in a substantially planar form are provided. In one embodiment the apparatus is manufactured as a unitary transmissive body comprising a collimation element and a redirection element, and optionally a transmissive element. In another embodiment the apparatus is assembled from one or more components. The apparatus and method are useful for providing sensing light for an optical touch input device.Type: ApplicationFiled: October 30, 2009Publication date: April 26, 2012Applicant: RPO Pty LimitedInventors: Andrew Kleinert, Duncan Ian Ross, Jonathan Payne, Warwick Todd Holloway, Graham Roy Atkins, Robert Bruce Charters, Kenli Chong, Dax Kukulj, Brigg Maund, Ian Andrew Maxwell
