    摘要： A large diameter injection water well is drilled using a drilling derrick and rotary drilling techniques. After snubbing in and drilling a short distance with drilling mud, a temporary drilling header is installed below the blowout preventers. Extending downward from the temporary drilling header is a drop pipe with a valve on the lower end thereof. Drilling pipe with attachments on the lower end thereof, are lowered into the drop pipe with the valve closed. After sealing to the drilling pipe, the valve is opened and the drilling pipe and attachments are lowered to the bottom of the well for the normal drilling operation. Thereafter, the drilling pipe and attachments are removed reversing the process of retracting into the drop pipe and closing the valve before removing the seal from the drilling pipe. The repeated insertion of the drilling pipe with various attachments on the end thereof in the drilling procedure occurs without having to kill or suppress the well until the final step when removing the drop pipe. Large diameter drillable centering guides insures pilot holes are being drilled in the bottom center of the large diameter injection water well.

    摘要： A platform is described for analyzing assessment data, including correlating assessment data with learning outcome data, and presenting analysis results through one or more interactive dashboards. A course syllabus and/or other course described information is analyzed to identify expected target outcomes to be achieved by students of the course, and to identify a relative weight of each of the various target outcomes based on their coverage in the syllabus. Assessment data describing a digitally administered assessment is analyzed to identify the categories that are assessed in the various questions of the test. The target outcomes are compared to the assessed categories to determine the extent to which the assessment is assessing each of the target outcomes, the degree of correspondence between the distribution of assessed categories and the distribution of target outcomes, and whether any gaps are present indicating that certain target outcomes are going unassessed or are insufficiently assessed.

    摘要： A device for removing obstructions impeding movement of a piece of equipment is disclosed. The device includes a sweep housing securely holding at least part of a rectangular sweep. A bristle portion of the sweep extends downward and away from the sweep housing, and includes a plurality of bristles. The sweep housing is made up of an inside bracket, which mounts to the surgical table by an adhesive strip or other means, and an outside bracket which comprises a thumbscrew or other locking mechanisms for securing the sweep housing and sweep in a fixed position with respect to each other. When an operator mounts the device, obstructions are pushed away from castors on the base of the surgical table by the one or more bristles.

    摘要： A monitoring device with a board case having an open end and a closed end partially defining a lower housing space; a lid connected to the board case at the closed end to define an upper housing space; a power supply within the first housing space; a printed circuit board assembly (PCBA) within the lower housing space and electrically connected through the closed end of the board case to the power supply, the PCBA having a CPU module with computer readable memory; a bracket assembly within the lower housing space; a camera module mechanically fixed to the bracket assembly; and a lens cover at least partially surrounding the camera module. In a network with a plurality of such devices, each device may be configured to communicate directly with each of the other monitoring devices without the use of a centralized server.
