Abstract: Jet grouting involves injecting grout into geological material to improve its quality; however, use of jet grouting is limited to situations in which the injection systems can be positioned relatively close to the region to be improved. This can be impractical (for example in heavily built up areas, rough terrain or beneath the seabed) or inconvenient (for example where closing a tunnel would be required). The present invention enables deployment equipment 41 to be passed down a bore in order to deploy material and/or equipment through a hole in the lining of a bore 43 into the underlying geology. In this way, underground assets may be repaired from a location external to the asset, allowing repair in situations where it would be impossible or cost-prohibitive to do so with conventional ground treatment techniques.

Abstract: Described herein are sustained release formulations of polymer-coated local anesthetic agents, and methods for using the same to relieve or manage pain, including postsurgical pain.

Abstract: Provided is an epidural device configured to inhibit or substantially or completely prevent further progression of an epidural needle upon entry of the needle into the epidural space. When the needle is inserted into the ligamentum of the patient's back, the device may be pressurized with fluid using the resistance of the dense ligament to maintain pressure. This pressurization may lock a pushing mechanism in place relative to the needle such that the pushing mechanism can be used to advance the needle. Once the epidural space is reached, the fluid (e.g., saline or air) enters the epidural space, and the release of pressure may cause the trigger mechanism to disengage from the sliding pusher, allowing the pusher to slide along the body of the construct. The device thus may provide the ability to detect the epidural space using pressure loss while preventing the needle from advancing into the dura once the space is reached.

Abstract: A syringe is provided having a hub with an orifice, first and second barrels having an interior surface to form respective lumens, a valve, and a test indicator. The first and second barrels slideably receive respective first and second plungers for movement therein. The valve is operable to provide a fluidly communicative path between the orifice of the hub and the first and second barrel lumens. The test indicator is responsive to at least one characteristic of a bodily fluid, the test indicator positioned to be exposed to any bodily fluid drawn into the first barrel lumen and visible from an exterior of the first barrel.

Abstract: In wireless local area networks utilizing frequency-hopping between different channels spaced over an allotted frequency band, two or more groups of transceivers in close proximity may be arranged to operate satisfactorily with the full bandwidth available to each by arranging that their hop sequences are kept separate. This may be achieved by arranging for the hop sequence of one group or of each group to skip at intervals from one point to another in the sequence, chosen at random.
