International Classification:

H04B 7/00

US Classification:

370310

Abstract:

Systems and methods for microwave tomography are described. According to various embodiments, signal strength values or other similar quality indications may be analyzed as they are received with packet data over a wireless network. The analysis may be used to determine the presence of a physical object substantially between communicating nodes in the wireless network. An output may be generated based on analyzed data. Other embodiments are described and claimed.

Filed:

Mar 6, 1987

Appl. No.:

7/022907

Inventors:

David R. Andersen - Solon IA
Robert R. Cuykendall - Iowa City IA

Assignee:

University of Iowa Research Foundation - Iowa City IA

International Classification:

G06F 756

US Classification:

364713

Abstract:

A reversible, all optical implementation of an interaction gate. One embodiment of the interaction gate is a dual-beam version of an optical nonlinear interface. A second embodiment is a dual-beam Fabry-Perot (F-P) switch. The device is a universal computation building block from which arbitrary computing circuits can be constructed.

International Classification:

A61M 5/315
A61M 5/20

Abstract:

An injection device includes a housing having an internal volume and a viewing portion. A movable seal is disposed in the internal volume and is movable from an initial position to an injection end position to urge a drug product out of the housing. An indicator assembly is disposed in the internal volume and includes a dose end indicator. The indicator assembly is biased from a dose remaining position toward a dose end position where the dose end indicator is visible through the viewing portion. A release mechanism releasably holds the indicator assembly in the dose remaining position and is linked to the movable seal such that the movable seal reaching the injection end position causes the release mechanism to release the indicator assembly to the dose end position.
