Filed:

Jun 6, 2002

Appl. No.:

10/163690

Inventors:

J. Christopher Flaherty - Topsfield MA
Christopher Carter Gregory - Newtown PA
Derek Dwayne Mahoney - Manalapan NJ
John Michael Margicin - Levittown PA

Assignee:

Insulet Corporation - Beverly MA

International Classification:

A61M 3100

US Classification:

604131, 604 67

Abstract:

A device for delivering fluid, such as insulin, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending along a longitudinal axis towards an outlet connected to the exit port assembly, and a plunger assembly received in the reservoir. The plunger assembly includes a two-way shape memory element connecting first and second lateral segments, and having a changeable length decreasing from an uncharged length to a charged length when at least one charge is applied to the shape memory element. Successively applying a charge and removing the charge from the two-way shape memory element causes longitudinal movement of the plunger assembly towards the outlet of the reservoir in order to cause fluid to be dispensed from the reservoir to the exit port assembly.

H04J 3/06

US Classification:

455 132, 455502, 455430, 455420, 370509

Abstract:

A communication network control method for a communication network including a hub and a plurality of user nodes includes adjusting system parameters to maximize communication data rate and minimize bit error rate given current conditions of the wireless channel, current loading of the network, and user constraints. In particular, the method includes transmitting a first and second frame with first and second control information from the hub to each user node, and transmitting a first and second respective data burst from each of the user nodes to the hub according to the first and second control information. The first data burst from each user node arrives simultaneously at the hub, and the second data burst from each user node arrives simultaneously at the hub. Further, the second data burst from each user node arrives immediately following the arrival of the first data burst from each user node.

Abstract:

A communication network control method for a communication network including a hub and a plurality of user nodes includes adjusting system parameters to maximize communication data rate and minimize bit error rate given current conditions of the wireless channel, current loading of the network, and user constraints. In particular, the method includes transmitting a first plurality of symbols with a first modulation and first forward error correction in a frame from the hub to a first user node, and transmitting a second plurality of symbols with a second modulation and second forward error correction in the frame from the hub to the second user node.

International Classification:

H04B 7/185

US Classification:

370316, 370315, 370321

Abstract:

A communication method for a communication network includes transmitting first control information for a first frame from a hub to a plurality of user nodes, and transmitting a first data burst in the first frame from a first user node and a second data burst in the first frame from a second user node to the hub according to the first control information. A start of the first frame from the first and second user nodes occurs simultaneously at the hub. The method also includes transmitting second control information for a second frame from the hub after transmitting the first control information, transmitting a third data burst in the second frame to the hub according to the second control information, and receiving the second frame at the hub following the first frame.

Abstract:

A communication method for a communication network includes transmitting first control information for a first frame from a hub to a plurality of user nodes, and receiving first data bursts in the first frame from first and second user nodes according to the first control information. A start of the first frame from the first and second user nodes occurs simultaneously at the hub. The method also includes transmitting second control information, based on demand information received from the first and second nodes, for a second frame from the hub after transmitting the first control information, receiving second data bursts in the second frame according to the second control information, and receiving the second frame at the hub following the first frame.

Abstract:

A communication system includes a hub, a repeater, and a remote. The hub is configured to adjust a transmission power of the remote depending on an external condition based on (i) a measured carrier-to-noise ratio CNof data transmitted from the hub to the repeater and back to the hub using a first signal, (ii) a measured carrier-to-noise ratio CNof data transmitted from the remote to the hub via the repeater using a second signal, (iii) a predetermined carrier-to-noise ratio CNof data transmitted from the hub to the repeater and back to the hub using the first signal under a clear sky condition, and (iv) a predetermined carrier-to-noise ratio CNof data transmitted from a reference remote to the repeater and back to the hub using the second signal under a clear sky condition.
