    Abstract: A hand carryable apparatus comprising a first power system, a second power system, a mechanical coupling, and an electrical coupling. The first power system comprises a first enclosure, a photovoltaic panel, a first power inverter, and a first alternating current interface coupled to the first output of the first power inverter. The second power system comprises a second enclosure, a battery, a second power inverter, and a second alternating current interface coupled to the second output of the second power inverter. The mechanical coupling and the electrical coupling removably couple the first power system to the second power system. The electrical coupling is capable of passing power between the first power system and the second power system. The second power system is capable of operating independently of the first power system.

    Abstract: An LED driver having an input to receive AC power from an AC power source, a semiconductor switch and an inductor controlled to produce a sinusoidal current drawn from the AC power source, and a large non-electrolytic (e.g. film) capacitor energy storage component. The semiconductor switch operates with a varying pulse-width-modulation frequency to regulate the voltage across the non-electrolytic capacitor energy storage component in such a way that a ripple current through the inductor is substantially smaller than a pulse-width-modulation cycle average current through the inductor. A DC-to-DC converter couples the energy from the non-electrolytic energy-storage capacitor to an LED string. A feedback loop allows the LED string to be regulated in either constant current mode or constant power mode and information for the feedback regulation is fed back across a high-voltage boundary using a low-cost signal transformer.

    Abstract: Tracking tags for attachment to an object or animal. The tracking tags may include low-power long-range transmitters drawing power from a battery or a renewable energy source. The tracking tags may also each include a microcontroller having a sleep-mode module enabling nearly no quiescent current to be drawn when the microcontroller is in a sleep-mode. The microcontroller may enter into a sleep-mode for long periods of time following a short period of sending data to the low-power long-range transmitter. The short period of sending data may be approximately one-twentieth of the long sleep-mode period. The tracking tags may also include sensors for determining an ambient temperature or biometric data about an animal to which the tracking tag is attached. Locations of the tracking tags may be determined using signal trilateration and/or signal triangulation.

    Abstract: A transmitter comprising a planar antenna including a ground plane and first and second spiral radiating elements wrapping around the ground plane, and a driving circuit. Proximal ends of the spiral radiating elements terminate near points located along a perimeter of the ground plane. Exactly one of the first and second spiral radiating elements are electrically isolated from the ground plane. The first and second spiral radiating elements are wound in the same direction for approximately a single turn and increase in thickness for approximately three-fourths of the turn. The driving circuit drives one of the first and second spiral radiating elements.
