Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.

Abstract: Embodiments disclosed include photovoltaic power systems and methods for manufacturing the same. A photovoltaic power system can include a photovoltaic array, a DC to AC inverter, a positive conductor electrically connecting a positive inverter terminal of the DC to AC inverter to the positive array terminal and a negative conductor electrically connecting a negative inverter terminal of the DC to AC inverter to the negative array terminal, a positive-conductor ground electrically connected by a switch to the positive conductor, and a negative-conductor ground electrically connected by a switch to the negative conductor.

Abstract: A photovoltaic power system can include a switched grounding system.

Abstract: A dynamically adjustable automotive air bag gas venting system including an inflatable cushion stored in a non-inflated configuration; an inflator receptive of a first command signal for initiating the inflator; a retainer plate; a base plate; a rotatable ring positioned between the base plate and the retainer plate and a pyrotechnic actuator receptive of a second command signal for initiating the pyrotechnic actuator so as to at least partially vent inflation gas from an air bag.
