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.

The invention relates to a microelectronic sensor device, particularly to a bio sensor with magnetic sensor units comprising excitation wires (11, 13) and a GMR sensor (12). The device further comprises a washing unit (20) consisting of a series of actuation wires (21) coupled to a driving unit (22). The driving unit (22) can activate the actuation wires selectively, wherein magnetic washing particles (2) are attracted to the activated wires. Shifting the activation pattern (R, S, T) then results in a corresponding movement of washing particles (2), which induces flow of the sample fluid that can wash away weakly bound and/or unbound target substance (3) from the sensor region (10) of the sensor units.

A semiconductor chip (CHP) and a semiconductor chip driver (RDR) communicate with each other in a wireless fashion. To that end, the semiconductor chip driver (RDR) generates an energy flux (FX1; FX2) that is concentrated on a transducer area (AT1; AT2) of the semiconductor chip (CHP). In the semiconductor chip (CHP), a wireless communication interlace (WCI) provides an electrical signal to a signal processing circuit in response to the energy flux (FX1; FX2). The signal processing circuit occupies an area (AS) that is substantially separate from the transducer area (AT1; AT2) on which the energy flux (FX1; FX2) is concentrated.

Detection means for detecting information in a signal, comprising integration means for integrating the signal over time such that the integration means is periodically reset at about the start time reference of a periodic time interval; and a sample&hold circuit for periodically sampling and holding the integrated signal (int) at about an end time reference of the periodic time interval and thereby delivering a further signal (fs). The detection means further comprises a chain (CHDL) of signal time delay elements, an input of the chain (CHDL) being coupled to receive the further signal (fs); and combining means (CBMNS) having combining inputs coupled to signal taps of the chain (CHDL), such that the number of the combining inputs and the position of coupling the combining inputs to the signal taps of the chain (CHDL) correspond to the information in the signal.
摘要:
A coder is fed with precoded data such that the absolute value of the running digital sum (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 code 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.

摘要:
When recording data on a record carrier of the DC content of the data recorded is important in order to allow accurate reproduction of the data. The Digital Sum Value represents the DC content; the Digital Sum Value can be controlled by replacing code words at the output of an encoder by code words that can never occur during encoding. The replacement code word has different parity than the code word it replaces. The resulting stream of code words is subsequent encoded using an NRZI coder, so that the change in parity resulting from replacement code word results in a change of polarity of the NRZI output. The replacement code word can thus be used to change the polarity of the NRZI output to keep the Digital Sum Value low.

A device and associated method for processing a digital information signal from a channel signal. The digital information signal is runlength limited with one or more constraints. The device comprises receiving means for receiving the channel signal and means for comparing a detected runlength with a predetermined value indicative of a minimum runlength constraint or a maximum runlength constraint of the channel signal and for generating a control signal when the detected runlength violates said constraint. The device further comprises substitute means for in response to the control signal deleting or inserting an element in the channel signal.

The invention relates to a substance determining apparatus for determining a substance within a fluid. Particles attach the substance and bind to a binding surface (30), wherein a sensing signal is generated depending on the bound particles. Binding events indicating a binding of a particle on the binding surface (30) are determined from the generated sensing signal, and the substance within the fluid is determined based on the determined binding events. During a procedure of determining a substance within a fluid, particles may bind to the binding surface and may leave the binding surface. Therefore, during this procedure a number of binding events can be determined being much larger than the number of bound particles. The determination of the substance within the fluid can therefore be based on a very large amount of data, thereby increasing the accuracy of determining the substance within the fluid.

The invention relates to a method and a sensor device (100) for detecting particles (MP) that are bound to the binding surface (12) of a carrier (11). The sensor device (100) comprises a microscope (50) for imaging bound particles (MP) onto an image sensor (53). In order to increase the spatial resolution of the microscope (50), a displacement unit (60,70,80) is provided that can displace the carrier (11) relative to the image sensor (53). The distance of a bound particle (MP) from the binding surface (12) and/or its lateral displacement in reaction to forces can thus be determine with high accuracy. This allows to discriminate specific bindings of large magnetic particles (MP) that are bound to the binding surface (12) via smaller target particles from nonspecific direct bindings.
