Abstract: This invention relates to a method and system for controlling light distribution in a space including multiple installed light sources and an external light source. The luminance level of light from said light sources is measured at different measuring areas within the space. A weighed luminance level is determined for each of the measuring areas based on the measured luminance levels, where the weighted luminance level indicates the contribution from the light sources to the measured luminance level at the different measuring areas. This weighed luminance level is used as a tuning parameter for tuning the emitted light at the installed light sources such that the weighed luminance level at each of the different measuring areas substantially matches a pre-defined target luminance level at the different measuring areas.

Abstract: A defibrillator electrode set for a defibrillator which senses the capacitance of an attached electrode set includes an electrode set coupled to the defibrillator by an adapter cable. The adapter cable and electrode set are pre-connected to the defibrillator prior to use. The electrodes are stored in a sealed foil package to retard gel desiccation prior to use. To reduce the capacitance of the electrode set seen by the defibrillator, the capacitance between the stored electrodes and the foil package is reduced by using a thicker dielectric layer for the layer of an electrode which opposes a wall of the foil package. In a constructed embodiment, one sixteenth inch thick polyethylene foam is used for the electrode layer opposing the wall of the foil package.

Abstract: A cooling device (1) using pulsating fluid for cooling of an object, comprising: a transducer (2) having a membrane adapted to generate pressure waves at a working frequency (fw), and a cavity (4) enclosing a first side of the membrane. The cavity (4) has at least one opening (5) adapted to emit a pulsating net output fluid flow towards the object, wherein the opening (5) is in communication with a second side of the membrane. The cavity (4) is sufficiently small to prevent fluid in the cavity (4) from acting as a spring in a resonating mass-spring system in the working range. This is advantageous as a volume velocity (u1) at the opening is essentially equal to a volume velocity (u1?) at the second side of the membrane, apart from a minus sign. Thus, at the working frequency the pulsating net output fluid can be largely cancelled due to the counter phase with the pressure waves on the second side of the membrane resulting in a close to zero far-field volume velocity.
