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.

A magnetic resolver that includes: an annular stator portion having a protruding core; an annular coil substrate on which a coil portion, which is disposed around the protruding core, is formed as a patterned thin-film coil; and a rotor portion disposed to face the stator portion from above, with the coil substrate interposed therebetween, wherein the amount of overlap between a top face of the protruding core and the rotor portion, when viewed from above, varies as a rotation angle of the rotor portion relative to the stator portion varies. The annular coil substrate may be constituted of substrate pieces that have shapes obtained by dividing the annular shape, which facilitates increasing the yield rate in the number of substrate pieces that can be produced from a substrate material.

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.

A light-emitting-element array has a semiconductor layer formed on a current-blocking layer. Light-emitting elements are formed in the semiconductor layer by diffusion of an impurity of a different conductive type. An isolation trench divides the semiconductor layer into a first region and a remaining region, and divides the array of light-emitting elements into segments disposed alternately in these two regions, each segment preferably including one or two light-emitting elements. A first shared interconnecting pad is electrically coupled to the light-emitting elements in the first region by electrical paths not crossing the isolation trench. A second shared interconnecting pad is electrically coupled to light-emitting elements in the remaining semiconductor region by electrical paths crossing the isolation trench. The array can then be driven by a number of separate interconnecting pads equal to half the number of the light-emitting elements.
