LED lamp apparatus for vehicles

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.

Force transfer mechanism for an engine

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.

Radiofrequency signal receiver with means for correcting the effects of multipath signals, and method for activating the receiver

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.
