The present invention provides a system (110) for controlling measurement and/or treatment means of a probe (10). The system (110) comprises a probe (10) with an outwardly curved probe head (11) having a contact surface (12) adapted for contacting skin (13) of a human or animal body. A plurality of pressure sensors (23) is distributed over the contact surface (12), the plurality of pressure sensors (23) being for obtaining a feedback signal indicative of locations where contact exists between the probe (10) and skin (13) of the human or animal body, also referred to as target locations. The system (110) furthermore comprises a controller (17) for selectively driving measurement and/or treatment means located at the target location based on the feedback signal from the pressure sensors (23). The present invention also provides a method for making a system (110) for controlling measurement and/or treatment means of a probe (10) and a method for controlling measurement and/or treatment means of a probe (10).

The location indicating device (10) comprises a matrix (7) of electrodes for determining skin resistance at different locations on skin of a human or animal body and a calculating unit (8) for calculating a location with highest skin resistance. The location indicating device (10) furthermore comprises visualisation means (9) for indicating the location of highest skin resistance to a user. The present invention also provides a method for making such a location indicating device (10) and a method for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body by using such a location indicating device (10).
Abstract:
An optical detector for spectroscopic analysis of a substance within a given spectrum has a first resolution at a first part of the spectrum (101,102) and a second resolution, different from the first resolution, at a second part of the spectrum, different from the first part of the spectrum. High resolution may be used at the important parts of the spectrum only, which thus results in less overall resolution. The detector may be used in a non-invasive glucose detection system having non-equally distributed spectral resolution.

Abstract:
Apparatus and method for sensing HO activity, and in particular blood glucose level based on an analyte level determination, the analyte being carboxyhemoglobin. In a preferred embodiment, HO activity and/or blood glucose level are extrapolated from Hb-CO level by determining an intermediate CO level. The apparatus and method are preferably non invasive.

Abstract:
Measuring reflectance of skin uses an adjustable probe having an illuminator (100) for directing light of more than one wavelength at a given angle onto the skin, a collector (95, 110, 122, 128) for collecting light reflected from the sample at a given angle, and an adjuster (5, 98, 122, 200, Ml, M2), for continuously adjusting the angle of the illuminating light or the collected light. Reflectance is determined according to a predetermined relationship between penetration depth at which the reflections occur, and the wavelength and the angle of adjustment. The angle can be continuously adjusted according to the relationship, or measurements can be selected, so as to maintain a constant penetration depth for a spectrum of wavelengths.
