Abstract: Systems for ultrasonic measurements of an inspection surface is described. An inspection robot with a payload moves in a direction of travel across an inspection surface. The payload has two sensor holders, the first sensor holder to hold a first UT array at a first orientation and the second to hold a second UT array at a second orientation A sensor holder linking component holds the two UT phased arrays in a parallel configuration along their long edges. An arm of the payload may be pivotably connected to both the sensor linking component at one end and a lift connection element on the other end. The lift component has a lift motor to raise the lift connection element. A rastering device moves the payload in a direction of inspection which is distinct from both the direction of travel and the parallel configuration of the two phased UT arrays.

Abstract: A system and method for providing chronic obstructive pulmonary disease (COPD) exacerbation risk notifications in real time or near-real time is described. Rescue and controller medication events are detected by sensors associated with the patient's medicament device/s, and provide a basis to determine to rescue and controller medication use trends for the patient. This data is analyzed to determine the patient's risk for COPD exacerbation after each event, and is used to send notifications to one or both of the patient and their health care provider.

Abstract: An electric pushback vehicle includes a frame having a forward portion and a rear portion. The vehicle further includes front drive axle and a rear drive axle configured to communicate power to ground engaging members. A traction battery is housed within the electric pushback vehicle and provides electric power to an electric motor to drive an output shaft. A transmission is connected to receive mechanical power from the electric motor through a torque converter.

An example system may have an inspection robot structured to move in a direction of travel along an inspection surface. The robot may have a payload with first and second sensor holders, each sensor holder structured to hold a UT phased array. A sensor holder linking component holds the first and sensor holders such that the two phased arrays are parallel to one another along a long edge of both the phased arrays. The system may have a rastering device to move the payloads in a direction of inspection, whether the direction of inspection is distinct from the direction of travel and distinct from the parallel orientation of the two phased arrays.

Abstract: According to embodiments described in the specification, an apparatus and method for lifting a roof onto a dwelling. A roof hoist with hooks and a frame is provided. Each hook is configured to slide under a portion of a roof and thereby support a portion of the weight of the roof. The frame is provided with locomotion means to facilitate positioning over a roof. A portion of the frame may be removed and lifted with the roof by overhead lifting means. The hooks are attached to the removeable portion of the frame. The roof may be deposited on a dwelling, and the hooks may then be disengaged. The removeable portion of the frame, along with the hooks, may be then be lowered and recoupled with the remainder of the frame.
