  • Patent number: 9008907
    Abstract: The present disclosure provides a system and method for managing a vehicle electrical system providing power to auxiliary systems. The system comprises a power control device with the ability to control the power to multiple auxiliary systems. The device has one or more sensor inputs for reading the system voltage and other data. The device can be configured with preset voltage thresholds for turning individual accessories on or off at predetermined voltage levels, or otherwise entering shutdown procedures. The system may also comprise a computer that is running dedicated software for managing the system and reconfiguring the device behavior.
    Type: Grant

  • Patent number: 8872130
    Abstract: A water purification system is described herein. The water purification system comprises a container configured to hold a liquid; an ultraviolet light source configured to irradiate liquid within the container; a reflector configured to reflect light from the ultraviolet light source into the container; a trough adaptor having a first end and a second end and configured to channel a liquid from the first end to the second end while exposing the liquid to light from the ultraviolet light source; and wherein the reflector is configured to reflect light from the ultraviolet light source both onto the trough adaptor and into the container.

  • Patent number: 8564220
    Abstract: A portable lighting device having one or more inputs, at least a first and second output, one or more light sources, an input sensor, an output sensor, an adaptive buck converter, a boost mechanism, an internal power source, and a controller. The input sensor is coupled to the one or more inputs and the output sensor is coupled to the first output. The input and output sensors are coupled to the adaptive buck converter and the boost mechanism and also to the controller. The controller is configured to instruct the adaptive buck converter to condition power inputs at the one or more inputs. The controller is configured to instruct the boost mechanism to boost a stored output from the internal power source.
