Abstract: The present invention relates to a device for measuring physiological signals of an object, for instance a human body of a patient. The device is provided with measuring means for measuring the physiological signals and with signal processing means for at least partially processing the measured physiological signals. According to the invention the device (1) comprises a first housing part (2) to which the measuring means (4A-4F) are attached. The device also comprises a second housing part (3) in which the signal processing means are accommodated. The housing parts (2, 3) are electrically connectable by means of a releasable coupling.

Abstract: Test printing apparatus for test printing, wherein printing ink is printed on a test substrate. An ultraviolet irradiation assembly is mounted adjacent the rotary path of the bearing surface bearing the test substrate, for emitting ultraviolet radiation against the test substrate. The apparatus has a control arranged for controlling the drive for imparting to the bearing surface a speed in the sense of rotation, which during the irradiation of the test substrate by the irradiation assembly is different from the speed that is imparted by the drive to the bearing surface during the printing of the test substrate. An irradiation assembly and a method for test printing are also described.
