Patent number: 9612182Abstract: A device and method for detecting fault conditions in a fluid connection system between a first fluid containing system including a first pulse generator (e.g., an extracorporeal blood circuit) and a second fluid containing system including a second pulse generator (e.g., a human or animal vascular system). A pressure sensor detects first pulses from the first pulse generator and second pulses from the second pulse generator. A time-dependent monitoring signal based on data obtained from said pressure sensor is generated and processed to calculate a parameter value indicative of the shape of at least part of a first pulse in the monitoring signal. The parameter value is evaluated to detect the fault condition. The fault condition may involve disconnection of an access device; reversed connection of access devices; occlusion of the fluid path through an access device; or infiltration in tissue surrounding an access point in the vascular system.Type: GrantFiled: December 22, 2010Date of Patent: April 4, 2017Assignee: Gambro Lundia ABInventors: Bo Olde, Kristian Solem

Patent number: 9506987Abstract: A system for tracking the capacity of a battery in a portable electronic device is described. While plugged in-to a power adapter, the system measures a first open-circuit voltage for the battery while the battery rests at a first state of charge. Next, the system causes the battery to transition to a second state of charge. During the transition, the system integrates a current through the battery to determine a net change in charge. Next, the system measures a second open-circuit voltage while the battery rests at the second state of charge. Finally, the system estimates a capacity for the battery based on the first and second open-circuit voltages and the net change in charge. This capacity measurement is repeated and the multiple results are fitted to a line. The slope of fitted line is used to estimate how the battery capacity has faded since last measured using traditional techniques.Type: GrantFiled: March 8, 2013Date of Patent: November 29, 2016Assignee: Apple Inc.Inventors: Nils E.
