Abstract: The invention relates to a sensor (102) and a control unit (702) for cooperation with the sensor. The sensor (102) serves for measuring a velocity of a fluid (308) flowing through a channel (306). The sensor (102) employs a thermal measuring principle, which measuring principle is robust regarding disturbances on the amount of power dissipated by the heating element (106). A sensor receiver (110) is arranged for receiving an electromagnetic radiation generated by a control transmitter (722) comprised in a control (702) unit for cooperation with the sensor (102). The electromagnetic radiation is employed for powering the heating element (106) which is arranged for heating the fluid. On the basis of a measurement signal generated by a transducer arrangement comprised in the sensor (102), a control actuator (724) controls the velocity of the fluid. For this purpose a sensor transmitter (116) is arranged for transmitting the measurement signal to a control receiver (734).

Abstract: A medical device comprising a probe for measurement temperature data of tissue within a patient's body is proposed. The probe (2) comprises a flexible substrate (3) attached to a medical device core (5), the flexible substrate (3) comprising one or more thermopiles (7) and may furthermore comprise resistors for measuring an absolute temperature and heat sources for locally applying heat. The thermopiles can be processed directly on a flexible polymer carrier or, alternatively, on a silicon substrate and transferred to a flexible carrier (3) enabling both, a highly flexible substrate (3) and very small structural dimensions for the thermopiles (7) and, possibly, the resistors and heat sources. Accordingly, measurement of temperature gradients of tissue being in contact to the medical device may be performed at high resolution allowing reliable detection of temperature anomalies e.g. due to malign tissue.

Abstract: A short-range radio transmitter of a communication device comprising a short-range radio and a long-range radio is controlled to delay packets which are scheduled to be transmitted at the same time as a long-range transmitter of the long-range radio commences or discontinues to transmit. A frequency synthesizer of the short-range radio is thereby not affected by a change in the power supply voltage which otherwise occurs at these moments due to transmission with high power by the long-range transmitter.

Abstract: The invention relates to a method, an apparatus and a packet transmission system for correcting errors in data packets (P) including information bits (IB) transmitted from a transmitter (TM) to a receiver (RC). The error correction method is characterized by the transmitter successively sending more parity bits on request of the receiver. Each set of additional parity bits is based on the original information bits, which are, however, reordered differently for each additional parity request. The receiver recursively performs a first error correction of said information bits (IB) reordered according to a first reordering pattern (REORD-A) using first parity bits (PA) for said original information bits (IB) reordered by using the same first reordering pattern, and a second error correction of said information bits (IB) reordered according to a second reordering pattern (REORD-B) using second parity bits (PB) for said original information bits (IB) reordered by using the same second reordering pattern.

Abstract: A method for calibrating a frequency device by monitoring its output cycles over a first plurality of monitoring windows is disclosed. An accumulation of these monitored cycles is used to determine a correction for the device over a second plurality of monitoring windows. A method for obtaining fractional correction values to be applied for controlling the frequency device is also disclosed.
