Abstract: A method and system are described for examining the interior material of an object from a surface of an object, using ultrasound having a frequency of at least 100 kHz. The method comprises the step of transmitting at least a first ultrasound signal by a first ultrasound transmitter of a first number of ultrasound transmitters to the interior material of the object for forming a first image in order to determine, according for example to the principle of inverse wave field extrapolation, where in the interior material of the object reflections and/or diffractions occur. Reflections and/or diffractions of the first ultrasound signal from the interior material of the object are received using a second number of ultrasound receivers which are acoustically coupled to the surface of the object at positions which are distributed in at least one dimension of the surface of the object.

Abstract: The invention describes a method of controlling the color of the light output of a lamp (1), which method comprises electronically collecting color data pertaining to a first color (C1) to obtain a first color description (D1), electronically collecting color data pertaining to a second color (C2) to obtain a second color description (D2), and combining the first color description (D1) with the second color description (D2) to obtain a target color description (DT). The target color description (DT) is transferred to a control unit (4) of the lamp (1), and the lamp (1) is driven according to the target color description (DT) to give a target color light output. The invention also relates to a system (3) for controlling the color of the light output of a lamp.

Abstract: Consistent with an example embodiment, here is a system for selecting the speed of a pointer on a display. The system comprises an analog input device arranged to generate an analog output signal (Vout), the analog input device suitable to be activated during an activation time (t). A signal processing means is arranged to select, depending on the activation time (t), a conversion function (f) for converting the output signal (Vout), the conversion function being different for different activation times, so that the converted output signal determined the speed of the pointer on the display. The speed of the pointer icon on the screen is both dependent on the time, t, and dependent on the output signal, Vout, of the analog input device itself, i.e. the pointer speed is a two-dimensional function f(t, Vout).

Abstract: A method for controlling printing actions of a print head (1) comprising pumps (10) filled with ink (18), and actuators (16) for generating actuation pulses acting on the ink(18), comprises the step of determining a characteristic frequency of the pumps (10). As the characteristic frequency of the pumps (10) is directly related to the geometry of the pumps (10), the characteristic frequency can be used as an indicator of the state of the pumps (10) and the volume of the ink droplets emitted by the pumps (10). In case a slight change of the characteristic frequency is detected, the actuation pulse is adjusted in order to still meet the requirements regarding the volume of the ink droplets. In case a relatively large change of the characteristic frequency is detected, the printing action of the pump (10) concerned is stopped, and may be taken over by another pump (10).
