IPC: G07D/
Filed: 2004-10-08
Abstract: A device for the handling of objects such as coins or similar items of different object types has a transport path with a plurality of separating stations for the objects. Each separating station is associated with an object type and is capable of assuming an activated position for separating a passing object, and a deactivated position, in which a passing object is not separated but continues past the separating station in question. The device has a sensor for detecting said object and for determining its object type, and a controller, which controls the separating stations by selective activation/deactivation depending on determined object types. The controller determines that a first train of objects has been detected, records information about an object type for said first train, determines that a second train of objects has been detected and records information about an object type for said second train. When controlling a separating station associated with the object type for said first train of objects, the controller uses the recorded information about the object type for said second train of objects.

Title: Implantable pump with reservoir level detector
Inventor: PETITHORY JEAN-SEBASTIEN
IPC: G01F23/26
Filed: 2006-10-30
Abstract: An implantable pump includes a base plate and a can that are parts of the pump housing. The base plate bottom divides the housing into a first electronics chamber and a second chamber. A bellows mechanism is connected to the base plate and is disposed within the second chamber. The bellow mechanism has an expandable sidewall and a bottom plate. The bellow mechanism divides the second chamber into a medicament receiving portion and a non-medicament-receiving portion. The bellow mechanism has an intermediate plate disposed within the medicament-receiving portion. A coil is disposed in a recess on the lower surface of the base plate, and the coil is spaced from an internal wall of the recess. The amount of fluid remaining in the implantable pump can be monitored by energizing the coil. A primary magnetic field is generated by the energized coil. A secondary magnetic field, which is dependant on the position of the bottom and intermediate plate of the bellow mechanism, couples back to the primary field affecting the electrical characteristics of the coil. The amount of fluid remaining in the reservoir is determined based on the resulting changes in the electrical characteristics of the coil.
