摘要： Photovoltaic (PV) array emulators and methods are described. In one example, a method for use in testing a PV inverter includes coupling a first PV inverter to an alternating current (AC) power source. A second PV inverter is coupled to receive an output of the first PV inverter. The first PV inverter is operated to emulate a PV array and provide a DC power output to the second PV inverter.

摘要： A mower blade bracket apparatus for safely changing mower blades includes a bracket body comprising a first half adjustably coupled to a second half to adjust for a distance between a first distal end and a second distal end. The first distal end and the second distal end have a first mounting aperture and a second mounting aperture extending therethrough, respectively. A pair of mounting bolts is coupled to the bracket body. The pair of mounting bolts is engaged with the first mounting aperture and the second mounting aperture to selectively engage a skirt of a lawn mower. A blade sleeve is coupled to the bracket body. The blade sleeve slidingly receives a blade of the lawn mower.

摘要： A method and device for reducing the damaging effects of a blast or concussive event includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during the incidence of the concussive event. Reducing blood out flow from the cranial cavity increases intracranial pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood out flow further increases the intracranial pressure, and thereby increases the pressure of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column. In addition, increasing intracranial pressure reduces the likelihood of brain injury and any associated loss of olfactory function.

摘要： A computer-implemented method for identifying utility usage from a historical utility file is disclosed. The method includes obtaining a file containing historical utility consumption of a dwelling over a time period; processing the file through optical character recognition (OCR); identifying contextual data from the OCR processed file; identifying chart data from the OCR processed file; extracting one or more values from the chart data, wherein the values correspond to one or more elements of the chart data; and contextualizing the extracted values from the chart data by applying the contextual data to the extracted value to obtain utility usage data.

摘要： An implant to be surgically positioned between two adjacent vertebrae made of a biocompatible material having two distinct areas of geometry—a front/anterior distracting portion and a second stabilizing back end/posterior portion. The device is inserted into the disc space on its side—in a first position—up until a point and then the device is rotated 90 degrees along a z-axis—into a second position—and then pushed the remainder of the way into the disc space. As viewed from the bottom of the device (in the second position—the position of the implant after rotation, the device is L-shaped, about L-shaped, or an angled dual leg configuration. A base member forms an angle anywhere between 30 to 150 degrees with a connected extended member.
