Abstract: Provided herein are purification, production and manufacturing methods for recombinant viral vector particles such as recombinant adeno-associated viral (rAAV) vector particles substantially free of empty viral particles; a population of recombinant adeno-associated vims (rAAV) particles purified using the method described herein, and a pharmaceutical composition comprising the purified rAAV.

Abstract: A supplemental braking system for controlling the braking of a towed vehicle. a supplemental brake application apparatus, a supplemental braking monitor, and a transmitter. The supplemental brake application apparatus is configured to be installed in a towed vehicle. The supplemental brake application apparatus is configured to move a brake pedal of the towed vehicle between a first position and a second position. The supplemental braking monitor is also configured to be installed in the towed vehicle. The supplemental braking monitor includes a proximity sensor configured to produce a proximity detection signal, and a mounting plate configured to secure the proximity sensor in a position such that the proximity sensor can detect movement of the brake pedal. The proximity detection signal is based at least in part on movement of the brake pedal. The transmitter is configured to send a brake status signal to a towing vehicle.

Abstract: An adjustable height platform is disclosed. The example adjustable height platform provides a first stage of uprights coupled to a lower platform and a second stage of uprights coupled to a lower platform. The first and second stage are coupled by a bracket with three pivot points. A first lower upright and a first upper upright couple to distinct pivot points on the bracket and a second lower upright and second upper upright couple to a common pivot point on the bracket. A first-to-second stage transfer mechanism transfer rotation force from the first stage of uprights to the second stage of uprights. The upper platform includes a height fixing mechanism release to interface with a height fixing mechanism coupled to the first upper upright to fix the height of the adjustable height platform.
