Patent number: 11880188Abstract: The present disclosure relates to the intelligent distribution of data for robotic, autonomous, and similar systems. To reduce the impact of multi-agent coordination on networked systems embodiments are disclosed that include the use of action-based constraints which yield constrained-action POMDP (CA-POMDP) models, and probabilistic constraint satisfaction for the resulting infinite-horizon finite state controllers. To enable constraint analysis over an infinite horizon, an unconstrained policy is first represented as a finite state controller (FSC). A combination of a Markov chain Monte Carlo (MCMC) routine and a discrete optimization routine can be performed on the finite state controller to improve probabilistic constraint satisfaction of the finite state controller, while minimizing impact to a value function.Type: GrantFiled: March 12, 2019Date of Patent: January 23, 2024Assignee: VIRGINIA TECH INTELLECTUAL PROPERTIES, INC.Inventors: Michael Fowler, Ryan Williams

Patent number: 9428404Abstract: Purified water can be obtained via a continuous or semi-continuous process by mixing a liquid composition (e.g., sea water or produced frac water) including water with a directional solvent to selectively dissolve water from the liquid composition into the directional solvent. The concentrated remainder of the liquid composition (e.g., brine) is removed, and the water is precipitated from the directional solvent and removed in a purified form. The solvent is then reused as the process is repeated in a continuous or semi-continuous operation.Type: GrantFiled: October 4, 2012Date of Patent: August 30, 2016Assignee: Massachusetts Institute of TechnologyInventors: Anurag Bajpayee, Stephan Josef Peter Kress, Kevin Kleinguetl, Gang Chen, Michael Fowler

Patent number: 9391749Abstract: Described are systems and methods for managing data traffic to a plurality of mobile devices over a wireless network. For each mobile device, a facility is provided that is capable of: (i) assigning a utility function to mathematically represent the value of a plurality of applications running on that mobile device with respect to a factor, (ii) aggregating the plurality of utility functions to generate an aggregated utility function corresponding to that mobile device, and (ii) communicating at least one of the associated aggregate utility function and a bid price based on the associated aggregate utility function over a network. A resource allocation is determined among a plurality of mobile devices based on a bidding process which accounts for the aggregate utility functions, and the data traffic between the mobile devices and the resource is managed using a network traffic shaping element according to the resource allocation.Type: GrantFiled: March 15, 2013Date of Patent: July 12, 2016Inventors: Ashwin Amanna, III, Joseph Mitola, III, Thomas Charles Clancy, III, Jeffrey H.

Publication number: 20060184141Abstract: An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient's body is disclosed. The access port includes a base, a bowl-shaped reservoir defined within the base by a smooth surfaced wall, and a septum secured to the base and enclosing the reservoir within the base. The access port also includes a reservoir outlet defined centrally within the reservoir. The bowl-shaped reservoir is defined by a continuous smooth-surfaced curvilinear wall. The reservoir may thus be sized and shaped as a parabola, or may be hemispherical or semi-hemispherical in cross-section. The reservoir outlet is defined at a center point on the bottom of the reservoir wall, may be partially or fully recessed within the bottom of the reservoir wall, and is also defined in the base tangentially with respect to the bottom of the reservoir wall.Type: ApplicationFiled: December 23, 2005Publication date: August 17, 2006Inventors: David Smith, Michael Fowler

Publication number: 20050231399Abstract: A serializer and a deserializer are disclosed and shown operating singly or as a pair. The invention operates independently from any outside system reference clock. The inventive system provides an internal bit clock that serializes the data when sending and de-serializes the data when receiving. A bit clock or pulse travels with the data word bits to define when a bit is stable. The system uses word boundary bits operating with a bit clock to distinguish different data words, as described in the parent application. The system operates either synchronously or asynchronously with the base computer or other such digital system, including I/O devices. The invention finds use where new data to be sent is strobed into the serializer, but also where a change in the data bit content itself will cause the changed data to be loaded into the serializer and sent bit by bit. The system operates where new data is strobed or loaded by the serializer (not the base computer system) when the last data word has been sent.Type: ApplicationFiled: April 15, 2004Publication date: October 20, 2005Inventors: Michael Fowler, James Boomer
