摘要： A sensor chip (1030) for gas has cells (200) for emitting and receiving ultrasound and is configured for a sufficiently large frequency range and for measuring concentration of at least one of the gas components based on at least two responses within the range. The frequency range can be achieved by varying the size of cell membranes (230), varying bias voltages, and/or varying air pressure for an array (205) of cMUTs or MEMS microphones. The sensor chip can be applied in, for example, capnography. A measurement air chamber (515) is implemented in the respiratory pathway (400), and it and/or the pathway may be designed to reduce turbulence in the exhaled breath (120) subject to ultrasound interrogation. The chip (1030) can be implemented as self-contained in the monitoring of parameters, obviating the need for off-chip sensors.

摘要： A coder is fed with pre-coded data such that the absolute value of the RDS of the code words as produced by the coder is limited. This is achieved by ensuring that in a group of 2 code words the RDS of the first code word is compensated by the RDS of the second conde word. The RDS at the end of the second code word is then zero and the excursions of the RDS from the start of the first code word until the end of the second code word are limited because there are only a limited number of bits that can contribute to an increase of the absolute value of the RDS. This principle can easily be applied to the 17PP coder.
摘要翻译：向编码器馈送预编码数据，使得由编码器产生的码字的RDS的绝对值受到限制。这是通过确保在一组2个码字中的第一码字的RDS由第二个对数字的RDS补偿来实现的。第二码字末尾的RDS为零，并且RDS从第一码字开始到第二码字结束之间的偏移是有限的，因为只有有限数量的位可以有助于增加RDS的绝对值。该原理可以轻松应用于17PP编码器。

摘要： The invention relates to a sensor device (100) and a method for the determination of the amount of target particles (1) at a contact surface (112) adjacent to a sample chamber (2). Target particles (1) in the sample chamber are detected by a sensor element (SE) and at least one corresponding sensor-signal (s, s′) is provided. An evaluation unit (EU) then determines the amount of target particles (1) in a first zone (Z1) immediately at the contracts surface (112) and a second zone (Z2) a distance (z) away from the contact surface based on this sensor-signal. In an optical measurement approach, frustrated total internal reflection taking place under different operating conditions (e.g. wavelength, angle of incidence) may be used to extract information about the first and second zones (Z1, Z2). In a magnetic measurement approach, different magnetic excitation fields may be used to excite magnetic target particles differently in the first and second zone (Z2). Moreover, the temporal course of a sensor-signal (s, s′) can be evaluated, particularly with respect to stochastic movements of the target particles (1).

摘要： A detection system (100, 150) for qualitative or quantitative detection of a magnetic field property of a modulated magnetic field is described. The modulated magnetic field may e.g. stem from an adjacent electrical current (Iadj) or magnetic particles. The detection system (100, 150) comprises at least one magneto resistive sensor element (102), a current controller (104) for providing a sensing current (Isense) flowing through the magnetic sensor element (102) and a controlling means (108). The controlling means (108) is adapted for deriving at a first frequency f1 a temperature-related parameter of the at least one magneto resistive sensor. The controlling means (108) furthermore is adapted for deriving a qualitative or quantitative characteristic of the adjacent electrical current (Iadj) or magnetic particles, taking into account the derived temperature-related parameter. This second frequency (f1) is different from the first frequency (f1}). The invention also relates to a corresponding method.

摘要： A visible pattern is obtained by modulating the digital sum value. Because the digital sum value modulation allows the choice of several different channel bits groups between DC control points, the selection of a group of channel bits resulting in a change of reflection. This creation of a visible pattern is highly suitable for Blueray as the parity preserving property of the channel code guarantees disparity inversion by the DC-control bit, which keeps the DSV excursions between hard limits. As a result only small DSV deliberate variations are required to produce a grating, which will not deteriorate the bit-detection margin of the optical disc.
摘要翻译：通过调制数字和值获得可视图案。由于数字和值调制允许在DC控制点之间选择几个不同的信道位组，所以选择一组通道位导致反射变化。这种可见图案的创建非常适合于Blueray，因为通道代码的奇偶校验保留属性保证DC控制位的视差反转，这保持DSV在硬限制之间的偏移。因此，仅需要小的DSV有意的变化来产生光栅，这不会劣化光盘的位检测余量。

摘要： The invention relates to a magnetic sensor device comprising excitation wires (11, 13) for generating a magnetic excitation field and a magnetic sensor element, particularly a GMR sensor (12), for sensing magnetic fields generated by labeling particles in reaction to the excitation field. The magnetic excitation fields are generated with non-sinusoidal forms, particularly as square-waves, such that their spectral range comprises a plurality of frequency components. Magnetic particles with different magnetic response characteristics can then be differentiated according to their reactions to the different frequency components of the excitation fields. The magnetic excitation field and the sensing current driving the GMR sensor (12) are preferably generated with the help of ring modulators (22, 24). Moreover, ring modulators (27, 29) may be used for the demodulation of the sensor signal.
