  • Patent number: 11883194
    Abstract: A system, method and apparatus is disclosed, comprising a biomathetical model for optimizing cognitive performance in the face of sleep deprivation that integrates novel and nonobvious biomathematical models for quantifying performance impairment for both chronic sleep restriction and total sleep deprivation; the dose-dependent effects of caffeine on human vigilance; and the pheonotypical response of a particular user to caffeine dosing, chronic sleep restriction and total sleep deprivation in user-friendly software application which itself may be part of a networked system.

  • Patent number: 11540723
    Abstract: A method of estimating a body temperature of an individual based on physiological data including a heart rate received from at least one sensor 510 and received environmental data. The physiological data and the environmental data are inputted into a model present on a processor 520. The model generates an estimated body temperature and an estimated physiological condition based on the inputs. The processor 520 compares the estimated physiological condition to a measured physiological condition in the physiological data. A controller 530 modifies at least one parameter in the model when the difference between the estimated physiological condition and the measured physiological condition is above a threshold.

  • Patent number: 11517203
    Abstract: An embodiment of the invention provides a method of estimating a body temperature of an individual where physiological data is received from at least one sensor 510. Environmental data is received and the physiological data and the environmental data are input into a model. The model generates an estimated body temperature and an estimated physiological condition based on the physiological data and the environmental data. A processor 520 compares the estimated physiological condition to a measured physiological condition in the physiological data. A controller 530 modifies at least one parameter in the model when the difference between the estimated physiological condition and the measured physiological condition is above a threshold.

  • Publication number: 20220199227
    Abstract: A system and method using a biomathetical model in conjunction with an optimization method for an individuals alertness impairment at a future time based on a known sleep schedule by adjusting the intake of caffeine over that schedule. In a further embodiment, placing constraints on the frequency, the dose amount, and/or total amount consumed over the course of the future schedule. In a further embodiment, optimizing the sleep schedule (prior to or independent of caffeine optimization) to decrease the individuals alertness impairment at the future time(s). In a further embodiment, adjust both the sleep schedule and caffeine intake to decrease the individuals alertness impairment at the future time(s). In at least one embodiment, the system including a mobile based system and/or a networked computer-based system.

  • Patent number: 11025580
    Abstract: A system and method for enabling delivering to a receiver of a message addressed to a non-electronically addressable entity ID associated with the receiver employs a database storing a plurality of verified electronically addressable and non-electronically entity IDs associated with the receiver, and a controller that upon receiving a message addressed to non-electronically addressable entity ID identifies the receiver and enables the receiver access to the message.

  • Patent number: 7043524
    Abstract: A network caching system for streamed applications provides for the caching of streamed applications within a computer network that are accessible by client systems within the network. Clients request streamed application file pages from other client systems, proxy servers, and application servers as each streamed application file is stored in a cache and used. Streamed application file page requests are broadcast to other clients using a multicast packet. Proxy servers are provided in the network that store a select set of streamed application file pages and respond to client requests by sending a response packet containing the requested streamed application file page if the streamed application file page is stored on the proxy server. Streamed application servers store all of the streamed application file pages. Clients try to send requests to streamed application servers as a last resort. Clients can concurrently send requests to other clients, to a proxy server, and to a streamed application server.
