摘要:
Embodiments of the present invention provide systems, articles of manufacture and methods for a telematic parametric speed metering system. In one embodiment, a system may determine a vehicle's location and speed. Once the location has been determined, corresponding geographical zone based speed limits and/or other information may be acquired via internal memory or data transmission. The speed of the vehicle may then be compared against the speed limits for the zone. If the vehicle's speed exceeds those speed limits, one or more of a plurality of actions may be performed including (but not limited to) warning the driver via a visual or audio signal, informing an authority agency via data transmission, logging the excessive speeding condition (e.g., time, date, speed, location, driver name, etc).
摘要:
A system adapted to generate hydrogen and oxygen for use in hydrogen-based fuel cells is described. The system includes a power source, a first conducting element connected to a positive terminal of the power source, a second conducting element connect to a negative terminal of the power source, and a conducting medium adapted to electrically connect the first conducting element to the second conducting element.
摘要:
A circuit includes a switching device for controlling a power signal to be applied to a heating device. A control circuit is configured for comparing a temperature signal, indicative of the temperature of the heating device, to a temperature setpoint to generate a gate pulse signal that controls the duration of the power signal to be applied to the heating device. The control circuit is further configured for comparing the duration of the power signal to be applied to the heating device to a minimum pulse duration and, if the duration of the power signal to be applied to the heating device is at least equal to the minimum pulse duration, providing the gate pulse signal to the switching device.
