Abstract: Disclosed is a method for determining onset of a sleep-related analyte. The method includes: obtaining first surrogate measurement(s) of a sleep-related analyte based on signal(s) obtained via sensor(s) during a first time period of observation; obtaining second surrogate measurement(s) of the sleep-related analyte based on signal(s) obtained via sensor(s) during a second time period of observation; determining a first surrogate function or value based on the first surrogate measurement(s) and a second surrogate function or value based on the second surrogate measurement(s); and predicting an onset of the sleep-related analyte for a first individual based on the first surrogate function or value and the second surrogate function or value such that the prediction of the onset of the sleep-related analyte is performed without determining an absolute concentration value for the sleep-related analyte.

Abstract: A device such as a disposable cartridge has an RFID tag (30) having an antenna (10), and a fluidic element (20, 160), the antenna having a shape to at least partly enclose an area, at least a part of the fluidic element being located in this area. By having such a structure, the device can be made more compact or the antenna can be made larger, and hence the costs for a given performance can be reduced, or the storage space for a given number of devices can be reduced.

Abstract: A cartridge for detection of target components in a liquid sample includes a sample chamber, at least two reservoirs that can be furnished with magnetic particles, and at least two corresponding sensitive zones in which solved magnetic particles and/or target components can be detected. When a magnetic actuation field of a given configuration is established in the sample chamber, the magnetic particles of different reservoirs migrate predominantly to different sensitive zones. Thus a mixing of magnetic particles can be avoided.

Abstract: A sensor system (100) includes a reader (150) with a sensor unit (155, 156) and an accommodation Space (151) for an exchangeable cartridge (110). The cartridge (110) is held in the accommodation space (151) by at least one contact element (111) which has an increased thermal resistance and/or a contact area of reduced size. Thus a more homogenous temperature distribution can be achieved within the cartridge (110), reducing distortions which might adversely affect optical measurements.

This allows stopping the fluid before reaching the measurement chamber (25) and controllably releasing the fluid for allowing the fluid to flow into the measurement chamber (25), if the sensing device is ready for analyzing the fluid.
