Abstract: A miniature sensor for detecting acceleration and deceleration processes has at least one bar-like spring element which is formed by a nanowire, which is connected by one end to the detector substrate and projects from the latter and which preferably carries at its free end a coating emitting a permanent magnetic stray field, or a nanoparticle of this type, wherein the nanowire and magnetic stray field coating, or mass, together form the inertial mass.

Abstract: In a method of forming micro traces, stamping techniques are employed to define a target pattern of the micro traces. The stamping is applied to electrically conductive material and may be limited to pressure, but a thermal stamping approach may be utilized. Following the stamping, a portion of the conductive material is removed, leaving the target pattern of conductive micro traces. In the pressure-application step, the pressure or the combination of pressure and temperature is sufficient to at least weaken the integrity of the bulk conductive material along the area of contact. Typically, this step causes shearing of the conductive material. Following the pressure-application step, excess conductive material is removed. In some embodiments of the invention, the thickness of the micro traces is not determined in a single step. The original thickness may be formed using a “seed” material. The subsequent material buildup may occur after the target pattern is established.

The systems and methods also convey additive solution from an additive solution source into the blood component collection flow channel. The systems and methods alternate the conveyance of blood cells through the filter with the conveyance of additive solution through the filter.

Abstract: A blood processing assembly comprises a frame rotatable about a rotational axis and a blood processing chamber carried by the frame for rotation about the rotational axis. An umbilicus has one end coupled to the blood processing chamber along the rotational axis and an opposite end held in a non-rotating position along the rotational axis. A mid region of the umbilicus extends, at least in part, outside the rotational axis. The frame carries at least one support channel, which is sized and configured to engage the mid region of the umbilicus. The support channel includes a side edge that is sized and configured to self-load the mid region of the umbilicus into the support channel in response to rotation of the frame in a designated direction.
