Abstract: A method of monitoring a use cycle or delivery process by a variable-dose delivery device involves, by an electronic unit associated with the delivery device, determining, during the use cycle, first and second event details of a first and second dispense event. Thereafter, determining cycle properties including at least one of a number of dispense events in the use-cycle and a holding time status indicative of a regular holding time having been observed at the end of the use cycle. Evaluating an injection criteria, including a multi-event-criteria based on an event detail of the first event, or a cycle criteria based on a cycle property of the use cycle, to derive an injection score of the second event, indicating a probability that a second dispensed dose has been injected and was not a priming or air shot. Determining and forwarding a cycle dispense dose based on the injection score.

Abstract: A bone registration system is disclosed. The bone registration system may have a device including a scanner arranged to scan a target surface area of bone to obtain scan data and a first communication component. The registration system may have also a first marker positionable on a first portion of bone. The first marker may include a second communication component arranged to transmit a location signal for indicating a position of the first marker in a plurality of dimensions relative to the device. The system may have also a registration unit that compares the scan data with surface data of the bone to generate position data identifying overlapping elements of the scan data relative to the surface data, determines location data from the location signal and determines a location of the first marker on a surface of the bone using the position data and the location data.

Abstract: A measuring device 1 configured to receive a drill bit 3, and determine the relative displacement of the drill bit 3, is disclosed. The measuring device 1 is configured to be deployed proximate to the material to be drilled, reset, and subsequently determine the relative displacement of the drill bit 3.
