A system for the metering and delivery of small discrete volumes of liquid is comprised of a small or minimal number of inexpensive components. One such component is a movable member, such as a miniature precision reciprocating displacement pump head, which is driven by an actuator that comprises a shape memory alloy material. The operating mechanism of the system is of little or minimal complexity. The system facilitates the precise metering and delivery of the small discrete volumes of liquid. Potential applications for the system include subcutaneous, long-term, automated drug delivery, for example, the delivery of insulin to a person with diabetes. In such an application, the small, simple and inexpensive nature of the invention would allow for its use as both a portable and a disposable system.

A high efficiency photovoltaic DC-DC converter achieves solar power conversion from high voltage, highly varying photovoltaic power sources to harvest maximum power from a solar source or strings of panels for DC or AC use, perhaps for transfer to a power grid at high power levels with coordinated control possible for various elements. Photovoltaic DC-DC converters can achieve efficiencies in conversion that are extraordinarily high compared to traditional through substantially power isomorphic photovoltaic DC-DC power conversion capability that can achieve 97%, 98%, 99.2% efficiency, or even only wire transmission losses. Switchmode impedance or voltage conversion circuit embodiments may have pairs of photovoltaic power interrupt switch elements and pairs of photovoltaic power shunt switch elements to first increase voltage and then decrease voltage as part of the desired photovoltaic DC-DC power conversion.

One or more outdoor lights may operate independently with sensing and control processes mainly on-pole, or may communicate as a networked array of poles, wherein a master / coordinating pole / node transmits signals from the networked array to a control station, and receive signals from the control station for the networked array, via call phone and / or satellite. Independent poles and / or the networked array of poles may be adapted for energy-saving processes; cooperation with the grid; renewable power production and storage by means of solar panels and associated batteries; and / or to provide Wi-Fi hot-spots, public safety alarms, information or data-analysis to the public or customers. An energy-saving active control system controls charging of the batteries and distribution of energy from the solar panel and / or the batteries, so that the batteries remain undamaged, and the light(s) remain operation even during the winter or other long periods of clouds and diffuse light. The active control of energy distribution by a load controller function may include dimming during the night, except when sensors detect motion, and, in extreme cloudy or diffuse-light periods, increasing increments of dimming and / or load shedding, to preserve the batteries and operability.

Laser radiation delivered to a treatment area causes vaporization of a substantially greater volume of tissue than the volume of residual coagulated tissue. The laser radiation may have a wavelength of about 300 nm to about 700 nm, may be used with a smoke suppressing irrigant, may have an average irradiance greater than about 5 kilowatts / cm2, and may have a spot size of at least 0.05 mm2. A laparoscopic laser device, for use with an insufflated bodily cavity, may include an elongate body adapted for insertion into an insufflated bodily cavity. A laser energy delivery element, at the distal end of the elongate body, may be coupleable to a source of tissue-vaporization-capable laser energy and capable of delivering laser energy along a laser energy path extending away from the laser energy delivery element. A smoke-suppressing liquid pathway, extending along the elongate body to an exit opening at the distal end, may be coupleable to a source of a smoke-suppressing liquid. The smoke-suppressing liquid is directed generally along the laser energy path. A remote visualization device may be used to view along the laser energy path.

Illumination systems, devices, and methods for cultivating biomasses. A bioreactor system is operable for growing photosynthetic organisms. The bioreactor system includes a bioreactor and an illumination system. The illumination system includes one more optical waveguides configured to light at least some of a plurality of photosynthetic organisms retained in the bioreactor. In some embodiments, the one or more optical waveguides include a plurality of structures configured to direct light energy from a solar energy collector, and a plurality of artificial light sources, along the interior of the waveguide. In some embodiments, the one more optical waveguides include a plurality of light-diffusing structures configured to guide at least a portion of the light from the solar energy collector and a plurality of artificial light sources directed along the interior of the waveguide, to the exterior of the waveguide.

A battery controller for charging and discharging a plurality of batteries is disclosed. The battery controller has a plurality of direct current to direct current (DC to DC) converters connected to each other in series. Each battery of a plurality of batteries is electrically connectable to a respective DC to DC converter. A co-ordinator connected to each of the plurality of DC to DC converters controls charging and discharging of the battery electrically connected to the respective converter. The co-ordinator can also control charging and discharging of any one of the batteries to ensure that the battery retains sufficient electrical capacity, and, to increase the longevity of the respective batteries. Because each battery is electrically connected to a respective DC to DC converter, the energy from one battery can be used to charge another battery in order to monitor battery characteristics including energy capacity of each battery. Each of the DC to DC converters is selected to operate preferably below 30 volts while the total voltage of the entire battery system can be much more than 30 volts depending on the number of DC to DC converters placed in series.

Solar cells are attached to vehicle components such as a moon roof (2) or truck bed cover (12, 13) to create modular solar panels. An adjustable mount (4, 10) can be attached to the solar panels to adjust the angle of the solar cells in a direction of the sun. Sensing for solar tracking the sun angle can be performed using solar cells of the solar panel itself, or a separate sensor (7). A telescoping moon roof mount mechanism (16) can allow a first solar panel (17) to be extended above a vehicle roof to allow additional solar panels (18, 19) to be telescoped out and also exposed to the sun. An additional battery (15, 100) can be mounted in the truck bed cover and connected in parallel with the hybrid battery (42).
