Abstract: An apparatus (1) for determining quality of a platelet concentrate (PC) (15) in a PC bag (10) comprises a movable bag holder (2) to carry the PC bag (10), a light system (20) with a light source (21, 24) to direct light (22) into the platelet concentrate (15) in the PC bag (10) for a measurement interval, and a detector system (30) with a light detector (31, 32) configured to detect light (23) from the platelet concentrate 15 during the measurement interval and generate a real-time detection signal. The apparatus (1) also comprises a controller (40) configured to determine platelet swirling based on the real-time detection signal and determine a quality parameter for the platelet concentrate (15) in the PC bag (10) based on the platelet swirling.

Abstract: The invention relates to an industrial truck with at least one drive battery and at least one apparatus (A) for determining the state of charge of the battery and to a method for operating such an industrial truck. The apparatus (A) for determining the state of charge of the battery includes a device (B) for determining the dynamic internal resistance and a device (C) for determining the internal cell voltage of the battery with the aid of the dynamic internal resistance.

Abstract: The present invention (HBX) describes a system and device design for measuring and analysis of properties in liquids with suspensions, preferably human body fluids e.g. whole blood and in the fluid existing substances and particles. By penetrating a sample of the liquid suspension with specifically calibrated light passing through a thin well defined layer of the liquid placed in a non added cuvette where the transmitted outgoing light from a measuring area is registered in a spectrophotometer adapted for the specific light and the optic geometrical system arranged for elimination of scattered light. The registered data points in the photometer is then processed in a series of steps for corrections and calculation of the values/results of the desired parameters by use of different algorithms in the microprocessor of the device for final presentation on a display, be stored in a memory and possible communication to other information receiving unit.
