  • Patent number: 9227014
    Abstract: Techniques for controlling an insulin pump include determining values for parameters selected from a group including a first prediction time horizon, a predicted glucose threshold (Goff) for turning the insulin pump off, a maximum shut off time within a time window, and duration of the time window. A safety rule is determined based on the maximum shut off time within the duration. Glucose readings are collected up to a current time. An expected current glucose value G and glucose temporal rate of change are determined based only on the glucose readings and a Kalman filter configured for noisy glucose readings. A glucose level (Gh1) is predicted for a future time that is the prediction time horizon after the current time. A command is issued to shut off the insulin pump if it is determined both that Gh1 is less than Goff and that the safety rule is satisfied.

  • Patent number: 7990906
    Abstract: A frame structure for a relay station operating in an OFDMA network includes a downlink sub-frame having a first allocated time zone dedicated for transmission between a base station in the network and the relay station, a second allocated time zone dedicated for transmission between the base station and a mobile station in the network, and a third allocated time zone dedicated for transmission between the relay station and the mobile station; and an uplink sub-frame having a first allocated time zone dedicated for transmission between the mobile station and the relay station, a second allocated time zone dedicated for transmission between the mobile station and the base station, and a third allocated time zone dedicated for transmission between the relay station and the base station.

  • Publication number: 20100174228
    Abstract: A system for predicting hypoglycemia based on continuous blood glucose monitor values is provided. The hypoglycemia detection algorithm is a set of individual alarms that are combined through a voting system into one combined alarm. The system could have five components and an overall voting algorithm that produces a binary alarm outcome depending on the number of constituent algorithms that report an alarm. A controller system automatically shuts off the insulin pump when pending or real hypoglycemia has been reached. The algorithms operate in a closed loop and automatically take action when the subject is asleep.

  • Publication number: 20080107072
    Abstract: Preamble modulation codes in an OFDMA network are assigned to one of at least two groups, one of the groups indicating that codes assigned to the group are for base stations in the network and a different one of the groups indicating that codes assigned to the group are for relay stations in the network. A mobile station attempting to enter or re-enter the network receives a signal transmitted from a station in the network and determines whether the station that transmitted the received signal is a base station or a relay station based on the group to which the preamble modulation code of the received signal was assigned.
