A method and a device for differentiation of substances in a body fluid, such as blood, plasma or used peritoneal dialysis fluid, for example for hemodialysis. The device has a compartment having several inlets for entering a body fluid, a transition fluid and a diffusion fluid for flowing parallel with each other in laminar flow layers with substantially equal flow velocities. The transition fluid layer is interposed between the body fluid layer and the diffusion fluid layer. The compartment further has a first outlet for removing the body fluid and the transition fluid and a second outlet for removing the diffusion fluid. Pumps are arranged for controlling the flow velocities so that a marker substance, such as albumin, will not diffuse from the body fluid layer across the transition layer, during the passage of the body fluid from the inlet to the outlet of the compartment.

Method for differentiation of substances

A device for measuring a vibration frequency of a mechanically vibrating string or rod, comprising a microwave transmitter for directing microwaves towards the vibrating string and a microwave receiver for receiving the microwaves amplitude modulated by the frequency of mechanical vibration. A member is arranged close to a vibration maximum of the vibrating string. The member is arranged on one side of the vibrating object and the microwave receiver is arranged on the other side thereof. The device is used for measuring temperature, pressure, torque, force or identity.

Device for improved response when measuring vibration frequency of a vibrating object

A marker for remote detection of articles has an elongated sensor element with magnetic and electric properties. The elongated sensor element provides an electromagnetic reply signal when receiving an electromagnetic input signal. The elongated sensor element modulates the electromagnetic reply signal in response to an external magnetic modulating field. The marker also has means positioned in a vicinity of the elongated sensor element in the marker. The means is adapted to influence either the magnetic or the electric properties of the elongated sensor element in response to incident electromagnetic or magnetic energy, so that either the electromagnetic reply signal itself or the modulation thereof is substantially changed from an active state to a deactivated state.
