Abstract: Methods and systems for releasing growth factors are disclosed. In certain embodiments, a blood sample is exposed to a sequence of one or more electric pulses to trigger release of a growth factor in the sample. In certain embodiments, the growth factor release is not accompanied by clotting within the blood sample.

Abstract: Disclosed herein are multi-cuvette cartridges, flow cells, and electrical pulse systems for treatment of large volumes of biological samples with pulsed electric fields. The multi-cuvette cartridges systems may include mechanical motors for automatic positioning and alignment between the cuvettes and the electrodes of the electrical pulse systems. The flow cell systems may include fluidic systems, such as pumps, nozzles and valves, which may operate in coordination with the electrical systems for efficient exposition of biological samples. Embodiments having flow cell systems that allow “on-demand” production of activated sample are also disclosed.

Abstract: A gate drive circuit device includes positive and negative pulse circuit portions each including a pulse diode and a pulse assembly connected in parallel with each other. The pulse assemblies each include another pulse diode and a resistor-capacitor assembly connected in series. The resistor-capacitor assembly includes a pulse resistor and a pulse capacitor connected in parallel. Each pulse circuit portion is connected with a different switch. Each pulse circuit portion is a passive device that is configured to activate a different switch responsive to receiving one or more voltage pulses from a power supply.

Abstract: A circuit assembly and method use a breakover device that changes states in response to a change in electric energy in a helper circuit that supplies current from a power source to a powered system. The helper circuit includes an inductive element connected with the powered system. The breakover device is in a non-conducting state prior to a discharge event from the powered system to prevent the current from the power source from being conducted through the resistive element. The breakover device changes to a conducting state responsive to the powered system discharging current into the helper circuit. The breakover device conducts the current that is discharged from the powered system through the resistive element to reduce the electric energy in the helper circuit from the current that is discharged.

Abstract: A switch assembly includes one or more solid state semiconductor switches configured to be disposed within a downhole pipe assembly. The one or more switches are configured to operate in a closed state to conduct electric current supplied by a power source disposed above a surface to pumps disposed beneath the surface to cause the pumps to extract a resource from beneath the surface via the pipe assembly. The one or more switches also are configured to operate in an open state to stop conducting the electric current from the power source to the pumps.

Abstract: A power system includes a first unit block having first resonant circuitry that receives power from a DC bus, a first controlled rectifier that provides a first portion of power to one or more loads at a first voltage level, and a first transformer coupled between the first resonant circuitry and the first controlled rectifier. A second unit block includes second resonant circuitry that receives power from the DC bus, a second controlled rectifier configured to provide a second portion of power to the one or more loads at a second voltage level, and a second transformer coupled between the resonant circuitry and the controlled rectifier. The first and second unit blocks are coupled in series to output a summation waveform.
