Systems and methods are disclosed, especially designed for very compact hardware implementations, to generate random number strings with a high level of entropy at maximum speed. For immediate deployment of software implementations, certain permutations have been introduced to maintain the same level of unpredictability which is more amenable to hi-level software programming, with a small time loss on hardware execution; typically when hardware devices communicate with software implementations. Particular attention has been paid to maintain maximum correlation immunity, and to maximize non-linearity of the output sequence. Good stream ciphers are based on random generators which have a large number of secured internal binary variables, which lead to the page synchronized stream ciphering. The method for parsed page synchronization which is presented is especially valuable for Internet applications, where occasionally frame sequences are often mixed. The large number of internal variables with fast diffusion of individual bits wherein the masked message is fed back into the machine variables is potentially ideal for message authentication procedures.

In an LED unit, all of eight LEDs are connected in series. The voltage of a power supply, that is, a battery of a vehicle, 12 V, is insufficient for the eight LEDs. To cope with this, a boosting circuit is provided within the control unit to boost the voltage to about 16 V which is then applied to the eight LEDs. The front end of the LED unit is connected to a constant-current circuit, and a voltage detection circuit is provided near and connected to this constant-current circuit for detecting the voltage applied to the constant-current circuit. The voltage detected by the voltage detection circuit is compared with a reference voltage drawn from the power supply, is amplified in an amplifier, and is input as a boosting control signal into the boosting circuit. The boosting control signal is output so as to regulate the boosted voltage in such a manner that the voltage detected in the voltage detection circuit is a lowest possible voltage.

The invention concerns an image-capturing apparatus and an imager. The image-capturing apparatus includes the imager in which a plurality of circuit cells are two-dimensionally aligned, and an electronic charge, photo-electronically converted from a received light and stored in each circuit cell, can be discharged from an arbitral circuit cell. The imager includes first group circuit cells to generate electronic charges corresponding to the pixels of the image including a subject, and second group circuit cells to generate electronic charges corresponding to an amount of light coming from the subject, the electronic charges further being converted to a detected value. In the imager, at least one of two operations of halting a generating-action of the electronic charges in the first group circuit cells and discharging the electronic charges from the first group circuit cells is performed, when the detected value exceeds a threshold value.

The invention relates to a radial sliding seal component (10), particularly for use in metering devices, such as syringes, pipetting piston-cylinder arrangements, and the like, comprising a sealing component (12) working together with at least one pretensioning component (14), wherein the sealing component (12) comprises a sealing segment (16) extending in the axial direction and in the circumferential direction, preferably running in the circumferential direction, on which a sealing surface (18) facing in a first radial direction for sealing and sliding contact in at least the axial direction is formed on a working surface extending in the axial direction and in the circumferential direction, preferably running in the circumferential direction, and on which a pretensioning surface (20) extending in a second radial direction opposite to the first is formed for engaging with the pretensioning component (14) for transferring the radial pretensioning force, wherein the pretensioning component (14) comprises a spring carrier (26) and a plurality of separately formed radial spring segments (22) compliantly supported at least in the radial direction on the spring carrier (26).

A skip mask mechanism is implemented in a disc drive in order to increase performance by minimizing the number of necessary disc rotations required while executing a set of pseudo-sequential commands. The drive includes an interface between the host computer and the drive, a read/write channel between the interface and the transducer/head, a formatter between the interface and the read/write channel for timing when data is transferred between the interface and the read/write channel, and a skip mask mechanism interposed between a target calculator and the formatter that provides a masked input to the formatter for controlling passage of data between the interface and the read/write channel.

A multiple watt-linkage force transfer mechanism is provided for an internal-combustion engine. The force transfer mechanism comprises two “bell cranks” that are used to drive a single crankshaft through a watt linkage mechanism. Each bell crank, in turn, is driven by two pistons through corresponding watt linkage mechanisms. The watt linkages connected to the pistons enable the connection ends of the pistons to travel along substantially straight paths, significantly reducing side loads against the piston walls. Also, all four pistons preferably drive a single connecting rod. This changes the role of the crankshaft—and the corresponding strength and rigidity requirements for the crankshaft—by reducing the necessary number of rod journals and main journals on the crankshaft.

In a display device, pixel electrodes I, II and III corresponding to color filters R, G and B are coupled to TFTs which are turned on in accordance with signals on gate lines G, and the drain (source) of the TFT coupled to the pixel electrode II is connected with the source (drain) of the TFT coupled to the pixel electrode III. A signal voltage is written in the pixel electrode I when the gate line G1a is in the “on” state, a signal voltage is written in the pixel electrode II when the gate line G1b is in the “on” state, and a signal voltage is written in the pixel electrode III when the gate lines G1a and G1b are both in the “on” state. Signal voltages are written in the pixel electrodes III, I and II in this order mentioned.

A rotation sensor for outputting a pulse signal, which has a frequency corresponding to a rotation speed of a rotor, to a wire. The rotation sensor includes a modulation unit and an output unit. The modulation unit modulates an information signal representing information other than the rotation speed into a carrier wave having a frequency higher than the frequency of the pulse signal. The output unit superimposes and outputs to the wire the pulse signal and the carrier wave. Accordingly, the rotation sensor performs stable information transmission that is not dependent on the rotation speed of the rotor.

The receiver (1) for radio-frequency signals (SV1, SV2, SV3, SV4), modulated by specific codes of transmitting sources, such as satellites (S1, S2, S3, 54), includes receiving and shaping means with frequency conversion for the radio-frequency signals for generating intermediate signals, a correlation stage formed of several correlation channels for receiving the intermediate signals and microprocessor means connected to the correlation stage in order to process the extracted data after correlation. Each channel includes a correlator in which the intermediate signals are correlated with at least two early and late replicas of the specific code of a visible transmitting source to be searched and tracked. The correlator further includes integrator counters for the correlated signals to provide a first amplitude value of the auto-correlation function of the early signals and a second amplitude value for the late signals. When multipath signals (SV1′, SV3′) are detected in the first operating channel, at least a second unused channel is configured, via the microprocessor means, and connected in parallel to the first channel. The second channel has the task of searching the maximum amplitude value between the two amplitude values of the first operating channel. The receiver, in particular of the GPS type, can be mounted in the case of a watch and powered by the energy accumulator or battery of the watch.
