Abstract: Disclosed is a buttock support for at least partial load-relief of the body weight of a person, the buttock support having two support regions adapted to receive at least part of a buttock region of the person. Also disclosed is a load-relief system having the aforementioned buttock support. The two support regions are separated from one another by a gap and are rounded. The gap separates the two support regions from one another centrally. The buttock support significantly simplifies the connection of a person to the aforementioned load-relief system to prepare for manual and/or automated physical therapy and also ensures that the thigh region, in particular the inner face of the thigh, and the groin region are accessible for further medical/therapeutic treatment by the medical staff.

Abstract: A method of detecting particles, e. g. proteins, after separation of particles based on their specific features, e.g. charge, size, shape, density, as series of single light scattering events created by the individual particles is described. The particles are separated from each other along the separation path and particles have specific arrival times at the target side depending on the particle features. The detecting step comprises an interferometric sensing of the light scattered at individual particles bound or transient in the detection volume. Parameters of the scattering light signals e.g. the interferometric contrast are analyzed for obtaining specific particle features, e.g. size, mass, shape, charge, or affinity of the particles. Furthermore, a detection apparatus being configured for detecting particles is described.

Abstract: A method of detecting particles (1), e.g. proteins, after separation of particles based on their specific features, e.g. charge, size, shape, density, as series of single light scattering events created by the individual particles is described. The particles (1) are separated from each other along the separation path (11) and particles have specific arrival times at the target side depending on the particle features. The detecting step comprises an interferometric sensing of the light scattered at individual particles bound or transient in the detection volume (30). Parameters of the scattering light signals e.g. the interferometric contrast are analysed for obtaining specific particle features, e.g. size, mass, shape, charge, or affinity of the particles (1). Furthermore, a detection apparatus (100) being configured for detecting particles (1) is described.
