Patent number: 10323545Abstract: A method for generating power from a heat source includes mixing a refrigerant in a liquid phase with a lubricating oil, heating the mixture to evaporate the refrigerant, mixing the heated mixture with additional refrigerant in a superheated phase, and atomizing the lubricating oil to disperse the lubricating oil within the refrigerant. The atomized lubricating oil and the refrigerant are passed through a decompressor to generate an electrical current. The refrigerant may be an organic material having a boiling point below about ?35 C. Related systems and heat engines are also disclosed.Type: GrantFiled: May 25, 2016Date of Patent: June 18, 2019Assignee: Heat Source Energy Corp.Inventor: Keith Sterling Johnson

Patent number: 8135808Abstract: An automated provisioning system for provisioning a service or device in a communications network, which system comprises a listener (2) adapted to receive a request from a user and a driver adapted to control operation of the service or device. The driver supports a describe operation, which enumerates which operations are available for the user and co-operates with a control processor (22), which mediates between the driver and a data store holding information on which operations are available for the user. When a request to provision an available operation is received, the control processor (22) mediates between the data store and driver to determine what information is required to provision the service or device and to permit the driver to provision the service or device. The system dispenses with the table driven approach of known systems.Type: GrantFiled: June 2, 2006Date of Patent: March 13, 2012Assignee: Jacobs Rimell LimitedInventors: Keith Sterling, Mark Pond, David Jacobs

Publication number: 20120006023Abstract: An apparatus, system, and method are disclosed for a loop thermal energy system. A heat pump heats a first fluid to first temperature using heat from a heat source. A first pressure tank charges with the heated first fluid while a second pressure tank discharges the heated first fluid stored from a previous charging. The discharged heated first fluid motivates an engine.Type: ApplicationFiled: March 22, 2011Publication date: January 12, 2012Inventors: Keith Sterling Johnson, Michael Troy Richardson, Brent Harvey

Patent number: 7398284Abstract: A method of management of concurrent sessions within a networked electronic system across multiple servers generally comprises defining a model of the system to be managed, and then defining policies, which policies are applicable to components of the model. Then, system components are modelled as entities in the model with hierarchical relationships between the entities. The entities each comprise a single physical or non-physical object in the system. The model is split into parts such that policy information for a given entity is held on a nominated server, with other servers being informed of where to find the policy information, determination of which policies to apply to a given request being made by a policy checker, which policies are then executed.Type: GrantFiled: October 15, 2002Date of Patent: July 8, 2008Assignee: Jacobs Rimell LimitedInventors: Keith Sterling, Richard Hughes, Allan Jenkins, William Box, Ian Middleton
