Abstract: Disclosed herein is a system and method for obtaining and generating motion capture datasets relating to various working activities for ergonomic risk assessment. An example system may comprise a computing device that obtains first data from multiple motion capture cameras, obtains second data from multiple visible light imaging sensors, calculates 3D positions of multiple reflective markers positioned on several subjects performing various working activities based on the first data, labels each marker to generate marker trajectories, performs gap filing and smoothing functions on the marker trajectories to generate global marker positions, transforms the global marker positions into a corresponding image coordinate system of each sensor to generate 3D pose data of the subjects at each sensor viewpoint, projects the 3D pose data into frames of the second data to generate 2D pose data, and generates a dataset comprising the second data, the 2D pose data, and the 3D pose data.

Abstract: A scalable water purification system for large-scale dialysis applications comprises a first carbon block vessel (worker vessel) connected in series to a second carbon block vessel (polisher vessel). The system includes one or more drain ports, air purge ports, pressure sensors, and sampling ports for monitoring and maintenance. A metal frame with levelling casters provides mobility, while at least one bypass valve allows the worker vessel to be bypassed for performance testing. Additional features include a multi-cartridge filtration unit for further contaminant removal, a UV-filtration unit for limiting biological growth, and a chlorine monitor for measuring chlorine and chloramine levels at various stages of water processing. This innovative design enhances water purification efficiency, reduces water usage, and simplifies maintenance compared to traditional granular activated carbon (GAC) systems.

Abstract: A system is disclosed for identifying industrial ergonomics risk root-causes and providing risk control actions. The system includes a processor configured to execute machine readable instructions to receive, from a computing device of a user, video of an individual performing a task and receive, from the computing device, textual information related to the task. The processor is also configured to process the textual information and the video of the individual performing the task through a deep learning framework to determine ergonomic risk root-causes. The processor is further configured to determine ergonomic risk control recommendations to mitigate the determined ergonomic risk root-causes. The processor transmits, to the computing device, information indicative of the ergonomic risk control recommendations and the ergonomic risk root-causes.

Abstract: A sterile holder for sterile surgical implants. The implant holder is an ergonomically shaped body of deformable material having an implant-receiving cavity similar in size and shape to the implant. To remove the implant from the holder, the surgeon mates a sterile tool to the implant and gently pries the implant out of the holder by deforming the body. Preferably the tool used to pry the implant out of the body is an insertion tool mated to the implant which is also used to insert the implant in a patient. In this way the surgeon retrieves the implant from its container without touching the container and directly inserts the implant in the patient without risking contamination: sterility is maintained for both the surgeon and the implant. In a preferred embodiment, the implant holder is configured to hold two pedicle screws and their set-screws.

Abstract: An expandable intervertebral spacer system having a cage formed by a top plate and a bottom plate which are held apart a changeable distance. An expansion mechanism within the cavity is configured to force the top plate apart from the bottom plate a desired distance. One expansion mechanism is an expansion spring that is held in a compressed state with a removable trigger wire that temporarily secures the top and bottom plates together. Once the spacer is implanted in a patient, the trigger wire is removed permitting the expansion spring to relax, in a single motion, to the farthest extent possible in an intervertebral space. The top plate and the bottom plate are locked apart using a locking mechanism made of two saw-toothed posts that cooperate to lock the top plate a desired distance from the bottom plate. The saw-tooth posts are biased against each other with a spring.

Abstract: Expandable intervertebral spacer system having a top plate and a bottom plate which are separated and held apart a changeable distance forming a cage. The plates are held apart by four locking mechanisms in the cage at or near the corners or the periphery of the plates, leaving the cavity of the cage substantially unobstructed. Each locking mechanism is made of two saw-toothed posts that cooperate to lock the top plate a desired distance from the bottom plate. The saw-tooth posts are biased against each other with a spring. Once the spacer is implanted in a patient with a removable insertion tool, the top and bottom plates are forced apart incrementally, one saw tooth at a time, in a ratchet-like motion, using a removable expansion mechanism. Optionally, each stanchion is surrounded by a sheath to prevent bone particles and other debris from interfering with the mating of the saw teeth.

Abstract: A snow plow and mount frame assembly permits an operator to attach and detach a snow plow to and from a mount frame secured to a vehicle, without the operator exiting a cab of the vehicle. The assembly comprises a mount frame, a snow plow frame, a plow blade, a first actuator for pivoting the A-frame relative to the lift frame, a latch mechanism, and a second actuator to either latch or unlatch the latch mechanism. When the vehicle is driven toward the snow plow the snow plow frame mates with the mount frame and an electrical connection is made between the vehicle electrical system and at least the first actuator without manual manipulation. The second actuator is energized to either latch the latch mechanism thereby securing the snow plow frame to the mount frame or unlatch the latch mechanism thereby freeing the snow plow frame from the mount frame.
