The invention, according to an embodiment, is a foldable, adjustable, and lockable cover for a plurality of rungs of a ladder. The device renders a ladder prohibitively difficult to climb. In an embodiment, the device is attached to a ladder using a lock, such as a bike lock or padlock, at a top portion of the device, rendering it difficult to for an unauthorized user to climb the ladder to cut any lock holding the device in place and/or remove the ladder.

An exemplary method includes accessing a source document where the source document is associated with a citation and copying a selected portion of the source document. Then, in response to copying the selected portion, the method includes generating a referenced element where the referenced element consists of the selected portion and a hyperlink associated with the citation. Finally, the method includes accessing a destination document and inserting the referenced element into the destination document. An additional exemplary method further includes storing a copy of the referenced element in a memory of an access device. Another exemplary method includes annotating the destination document and generating an annotated destination document. Another exemplary method includes printing, within a single print session, the annotated destination document and the source document. Yet another exemplary method includes printing, within a single print session, a non-annotated destination document, the annotated destination document and the source document.
摘要:
A method and a device are disclosed which seek to improve productivity of the installation of fasteners. This improved productivity is achieved by holding a fastener to a driving tool with a mechanical means for a substantial portion of an installation sequence to prevent nuisance disengagement between fasteners and their driving means including dropping of fasteners early in an installation cycle. The productivity of this fastener holding approach is best realized by allowing a streamlined operation with little interaction between the fastener driving device and an operator. Specifically, a fastener installation device is described which requires no direct manipulation of said device during the sequence of loading a fastener into said device, installation of said fastener with said device, disengagement of said device from said fastener to allow complete installation of said fastener, and loading a subsequent fastener.

A turbine includes an inner casing to which at least a stator vane of a turbine section is mountable, and an outer casing arranged around the inner casing in such a way that an outer cooling channel is formed between the inner casing and the outer casing. The outer cooling channel includes a fluid inlet through which a cooling fluid is injectable from an outer volume of the turbine into the outer cooling channel. The cooling channel includes a fluid outlet such that the cooling fluid is exhausted into an inner volume of the turbine. The fluid inlet is located with respect to the fluid outlet such that the cooling fluid inside the outer cooling channel includes a flow direction which has a component that is orientated in opposite direction with respect to a main flow direction of a working fluid of the turbine.

A downhole tool and method of operation thereof is provided. The downhole tool may be configured to permit fluid communication between a combined flowbore of the casing string and the downhole tool and the subterranean formation or wellbore, or both, after a pressure test has been completed, a second threshold pressure is reached or applied, and a third threshold pressure has been applied to the downhole tool.

The systems and methods described herein include a low-noise apparatus for providing positive air pressure to a patient. The systems may include a housing with an inlet port, a vibrationally isolated blower unit positioned in an acoustic chamber, and an outlet port for delivery of the pressurized air from the blower unit. The acoustic chamber may include noise attenuators, such as walls, which adjust airflow so as to reduce the overall noise output of the system.

In a method and apparatus for identifying regions of interest in medical images of a subject, in particular images captured by a medical imaging apparatus, such as a PET scanner, a list of voxels of the image is obtained, and sorted according to a first variable. A user-selection of an initial voxel in the image is then registered, and at least one voxel or group of voxels from the sorted list is selected as a region of interest, according to a property of the at least one voxel or group in relation to the user-selected initial voxel. The image may be pre-processed to generate the sorted list of voxels, following which the user selection of the initial voxel is registered.

An ice chopping assembly includes at least a blade, shaft, handle, and force enhancing assembly. The blade may includes at least one face and at least one edge cooperatively structured to break ice formed on a solid surface, but may otherwise be appropriately configured to break ice. The shaft is rigidly affixed to the blade opposite the edge. The handle may be rigidly mounted to a bushing, through which a restricting device may travel. The restricting device includes a stop structure about which the bushing may be concentrically disposed. At opposite ends of the stop structure may be stop segments which limit the reciprocal travel of the blade relative to the handle.
