Abstract: A motorized landing gear including: a motor housing that encloses a motor; a gearbox; a controller; and a power source powering the motor and the controller. The gearbox attaches to an axle having two ends, with a first end of the axle connecting to a first landing gear leg and a second end of the axle connecting to a second landing gear leg. The motor connects to said gearbox and the controller instructs the motor to rotate. The rotation of the motor transfers power to the gearbox, which rotates the axle. The rotation of the axle in a first direction simultaneously telescopes the landing gear first leg and the landing gear second leg; and the rotation of the axle in a second direction simultaneously retracts the landing gear first leg and the landing gear second leg.

Abstract: This disclosure relates to a sensor-based monitor for movements of workers. Multiple inertial sensors are attached to different body parts of the workers. A mobile device application receives the inertial movement data from the sensors and identify movement patterns by applying a trained machine learning model to the inertial movement data. The application then determine for each movement pattern an amount of time that movement pattern occurred and accessing a database to retrieve stored data on an association between the identified movement patterns and injuries. The application calculates a risk value indicative of a risk of injury of the worker as a result of performing the identified movement pattern for the determined amount of time and produces a report detailing the risk value for each of multiple risk categories.

Abstract: A cross tie bracket that is attachable to a rod and a building structural element. The cross tie bracket has a generally cylindrical body sized to receive the rod and a gusset disposed between the body and a base. The base has a series of apertures formed therein for inserting fasteners through the base into the building structural element, temporarily securing the cross tie bracket to the building structural element with screws, and for providing alignment of a temporary drill guide with the base. A first and second end plate are disposed adjacent to each respective end of the cylindrical body. Each of the end plates has a rod aperture sized to receive the rod. Accordingly, by inserting and securing the rod to the end plates, it is possible to attach the rod to the building structural element.

Abstract: An anchor having multiple legs for a concrete wall. The anchor has an interface plate with two sides. Disposed on a first side is a stud that is connectable to a bracket. Disposed on the second side of the interface plate are at least two legs. Each of the legs is insertable and secured to a respective hole formed in the concrete wall with epoxy. Once the epoxy cures, the leg attaches the anchor to the concrete wall.
