Title: Telemetry wave detection apparatus and method
Inventor: CAMWELL PAUL L
IPC: E21B47/16
Filed: 2007-04-12
Abstract: Non-contacting means of measuring the material velocities of harmonic acoustic telemetry waves travelling along the wall of drillpipe, production tubing or coiled tubing are disclosed. Also disclosed are contacting means, enabling measurement of accelerations or material velocities associated with acoustic telemetry waves travelling along the wall of the tubing, utilizing as a detector either a wireless accelerometer system or an optical means, or both; these may also be applied to mud pulse telemetry, wherein the telemetry waves are carried via the drilling fluid, causing strain in the pipe wall that in turn causes wall deformation that can be directly or indirectly assessed by optical means. The present invention enables detection of telemetry wave detection in space- constrained situations. The invention also teaches a substantially contactless method of determining the time-based changes of the propagating telemetry waves. A final benefit of the present invention is that it demonstrates a particularly simple contacting means of directly measuring wall movements in live coiled tubing drifting environments.

Title: Pharmacy medication verification system
Inventor: WAGNER DAVID J
IPC: G16H20/13
Filed: 2008-11-26
Abstract: A pharmacy medication verification system is particularly useful for verifying medications to be dispensed to hospital patients while minimizing or eliminating verification by a pharmacist. Typically, a technician or robot picks the medications from storage bins in accordance with a medical prescription or stocking order and uses various sensors to ensure that the correct medication was picked and enters a medication container. The system typically provides correct and incorrect medication indicators as well as correct and incorrect entry indicators. Error reports may be generated when appropriate to communicate any relevant errors to the pharmacist, who can then verify that the correct medications are in the container. In one aspect, the containers are in the form of patient drawers which fit within a cart for delivery to hospital rooms. A containment device may be used to secure the drawer or other container during the verification process.

Title: Self-stowing jumpseat for aircraft
Inventor: ISHERWOOD CHRISTOPHER
IPC: B60N2/68
Filed: 2012-01-19
Abstract: A self-stowing jumpseat consists of a seat frame that is deployed by pulling the seat frame out of a pocket formed in the edge of a bulkhead in a manner similar to the action required to close a pocket door. Once the seat frame has been deployed and locked in position, the seat pan is folded down to enable a user to be seated.  The seat pan is spring-loaded to fold up, so that when the user vacates the seat, the seat pan automatically folds up into the closed configuration. As it does so, an interlock lever attached to the seat pan trips the seat frame locks from their locked to their unlocked positions. The seat frame has a retraction mechanism that urges the seat into the pocket.  Accordingly, as soon as the seat pan interlock lever releases the seat frame locks, the retraction mechanism causes the now-folded seat frame to move automatically into the stowed position within the bulkhead.
