Abstract: A measuring arrangement for in-vivo determination of the lactate concentration in blood by means of electrochemical impedance spectroscopy, comprising a substantially flat shaped probe having a longitudinal extension, a transverse extension and a thickness, wherein the longitudinal extension and the transverse extension of the probe are each a multiple of the thickness of the probe, an analyzer circuitry connected to the probe, and communication means connected to the analyzer circuitry for transferring data via a WPAN, wherein the substantially flat shaped probe is arranged at an edge of the measuring arrangement, so that the probe, during operation of the measuring arrangement, faces the animal or human body to be examined, in such a manner that the probe is arranged with its longitudinal and transverse extensions approximately parallel to the surface of the body to be examined, a wristband therefor, and a method for the operation thereof.

Abstract: An archive in a computer based search server can include a fixed-width field array storing numeric rank data associated with documents. The search server can provide search results using the numeric rank data obtained from the fixed-width field array.

Abstract: Systems and method, remotely monitor; the times, at which a user or users access certain facilities. Particularly, but not exclusively such systems can be used to monitor, at a central location, an employee's working times, at remote locations, for example building sites. The use of biomettic scanners in such systems can allow users' attendance to be monitored remotely without the need for supervision.
