摘要:
An engine includes a piston slidably disposed in a cylinder with a closed end. The engine further includes a converter operable with the piston to convert mechanical energy of the piston to electrical energy in the converter in a stroke and convert electrical energy of the converter to mechanical energy in the piston in at least one other stroke.

A method of transporting liquefied breathing gases in underground mines includes providing a conduit system that extends within a mine shaft to a work space below ground where the conduit system includes an outlet positioned in the work space, delivering liquefied breathing gases through the conduit system, and vaporizing the liquefied breathing gases at the outlet of the conduit system.
摘要:
Exemplary methods, systems and components disclosed herein provide propagation of light signals from an external source to a borehole mining mole which includes an optical/electric transducer configured to provide propulsive power for the borehole mining mole and its associated mineral prospecting tools. Some embodiments include one or more umbilicals connected from a remote source location to an onboard reel incorporated with the borehole mining mole. The umbilicals are spooled outwardly or inwardly from the onboard reel during traverse of the borehole mining mole along a path in an earthen environment.
摘要:
The present invention may include measuring energy usage of one or more appliances for a selected usage metric, receiving reference energy usage data indicative of energy usage of one or more reference appliances for the selected usage metric, comparing the measured energy usage of the one or more appliances for the selected usage metric to the one or more received sets of reference energy usage data for the selected usage metric, and reporting an amount of energy savings based on the comparison of measured energy usage of the one or more appliances and the one or more received sets of reference energy data.
摘要:
A method of retrofitting for electrical power generation an internal combustion engine (including a plurality of pistons connected to a common crankshaft) includes applying to at least one and optionally to each piston a power converter operable to convert mechanical energy of the piston to and from electrical energy.
摘要:
One aspect relates to combining an at least one LED-based secondary general illumination lighting with an at least one primary general illumination lighting to at least partially provide an at least one combined general illumination lighting. The aspect further comprises sensing one or more sensed optical characteristics of an at least one alternate general illumination lighting. The aspect further comprises controlling at least one controlled optical characteristics of the at least one LED-based secondary general illumination lighting to control the at least one combined general illumination lighting at least partially responsive to the sensing the one or more sensed optical characteristics of an at least one alternate general illumination lighting.
