The present invention encompasses a high efficiency pulse width modulator comprising: a variable duty cycle oscillator for receiving an input signal and providing a low level switching signal; a source voltage differentiation dependant positive switching signal circuit for receiving the low level switching signal, a stable reference signal, a sample of a positive supply voltage signal, and an error signal and the providing a positive supply switching signal and a reference signal; a positive supply switching circuit for receiving the positive supply switching signal and providing an output signal to an inductive load; an output voltage dependant negative supply switching signal circuit for receiving the output signal and a negative supply voltage signal and providing a negative supply switching signal; a negative supply switching circuit for receiving the negative supply switching signal and providing clamping of the inductive load to the negative supply, an output sourced charge pump for receiving the output signal and the positive supply voltage signal and providing a high voltage power supply; an output comparison circuit for receiving a sample of the output signal and a reference signal from the positive supply switching circuit, comparing the output signal to the reference signal and turning off the positive supply switching circuit when the output signal is lower than the reference signal; and a timing circuit for receiving an error signal from the comparison circuit and providing a feedback signal to the error circuit.

A common inexpensive device such as an automotive internal rear view mirror, cell phone, CHMBL (center high mounted brake light), license plate or stand-alone housing incorporates an emergency warning system to detect a predefined signal emitted by an right of way vehicle such as an ambulance, police car, fire engine, or train. The right of way vehicle sends out a specific predefined signal to a predefined area. The specific predefined signal is picked up by a receiver of the present emergency warning system. Then, after verification of the specific predefined signal, the emergency warning system emits a warning, preferably an audio warning.

Novel storage area networks (SANs) and methods of operation thereof utilize a plurality of hosts coupled via an interconnect with one or more storage units. A manager device, process or other functionality in communication with a plurality of agent processes, devices or other functionality, each of which is associated with a host. The agents identify attributes of (i) their associated hosts, (ii) interconnect to which that host is coupled, and / or (iii) storage units to which that host is coupled via the interconnect. The manager responds to these attributes identified by the agents to manage the SAN. The manager can be implemented on a first digital data processor and the hosts on further digital data processors. These digital data processors can be coupled via a first network, e.g., an IP or other network, to support communications between the manager and the agents. A second network, e.g., SCSI and / or fiber channel based fabric, separate from the first network, can be utilized as the interconnect between the hosts and the storage devices.

A common inexpensive device such as an automotive internal rear view mirror, cell phone, or CHMBL (center high mounted brake light) incorporates an emergency warning system to detect a predefined signal emitted by an right of way vehicle such as an ambulance, police car, fire engine, or train. The right of way vehicle sends out a specific predefined signal to a predefined area. The specific predefined signal is picked up by a receiver of the present emergency warning system, which is preferably housed in a rear view mirror or cell phone, and which is always on, whether the internal rear view mirror, cell phone, or CHMBL is powered on or powered off. Then, after verification of the specific predefined signal, the internal rear view mirror, cell phone or CHMBL emits a warning, preferably an audio warning from a speaker housed in the internal rear view mirror, cell phone, or CHMBL. The emergency warning system can be incorporated into a telematics unit.

The invention relates to an internal combustion engine having a turbocompound system. The turbocompound system encompasses an exhaust-gas turbocharger, a turbo intercooler, and a power turbine. The power turbine is connectable, via a transmission with clutch, to the crankshaft of the internal combustion engine. A connectable compressor, which is couplable either to the power turbine or to the internal combustion engine, is received in a multiple-flow intake pipe.
