A deformable release device is disclosed to be used with downhole setting tools. The deformable release device may provide a releasable detachment to any customary setting tool, such as electric line, hydraulic, hydrostatic, and mechanical setting tools, used to set a downhole packer-type device. The deformable release device allows for the automatic release of downhole setting tools at the application a predetermined force, similar to a shear pin or shear stud. However, since the deformable release device deforms rather than shears or breaks, the releasing device minimizes the debris or remnants of the device left in the wellbore.

An obstacle avoidance system according to the present invention may include an input control device, a sensor suite, and a communication feedback loop. The input control device is preferably operable to create a first force, while the sensor suite is configured to detect nearby obstacles, and the communication feedback loop is in communication with the input control device and the senor suite so that said communication feedback loop is operable to generate a command signal in response to detection of a nearby obstacle. The command signal being operable to cause an actuator to generate a second force different from said first force. Preferably, the obstacle avoidance system is used in combination with an apparatus, such as a rotary wing aircraft, wherein the input control device at least partially controls the movement of the apparatus in response to a user's input. The user's input tending to cause the first force to move the apparatus in a first direction. The sensor suite being preferably mounted to the apparatus in order to detect nearby obstacles which may contact the apparatus if the apparatus is moved in the first direction. The communication feedback loop at least partially augmenting the user's input such that the second force tends to preclude the apparatus from moving in the first direction and thus tends to preclude the apparatus from contacting the detected obstacle. More preferably, the second force tends to cause the apparatus to move in a second direction different from the first direction and away from the detected obstacle.

Monochloramine is efficiently manufactured by introducing controlled quantities of an ammonia source and a chlorine source in a small side-stream of water in a small diameter pipe under turbulent flow conditions. The ammonia source and chlorine source can be injected in either order and are separated by a sufficient distance to ensure that the first chemical is adequately diffused throughout the water prior to the injection of the second chemical. A sufficient length of a mixing chamber insures that turbulent flow is maintained for a length of time sufficient to thoroughly mix the two chemicals to produce monochloramine. This mixing technique allows for the manufacture of high concentrations of monochloramine at atmospheric pressure without off gassing.

A stent-graft including a stent member having an inner surface and an outer surface, a generally tubular graft member and a coupling member that couples the stent member to the graft member. The coupling member, which is the preferred embodiment is in the form of a ribbon, covers only a portion of the inner or outer surface of the stent member and secures the stent member and graft member to one another. Alternatively, the coupling member can be described as interconnecting less than entirely the inner or outer surface of the graft member to the stent member. With this construction, regions of the stent member do not interfere with the coupling member. Shear stresses between the stent member and the coupling member and the risk of tearing the graft or coupling member or delamination therebetween may be reduced as compared to a fully enveloped stent member. This construction also provides improved flexibility and kink resistance.

The invention provides an apparatus and method for storing and transporting peritoneal dialysate in dry or lyophilized form, and for forming a deliverable peritoneal dialysis solution therefrom. In one embodiment, a dry reagent bed, including reagents sufficient to produce a dialysis solution, is suspended in a diluent flow path through the apparatus housing. Continuous pressure on the reagent bed causes the bed to compact as it erodes when purified water is passed through the housing. The pressure ensures complete and even dissolution of the reagents. Through dry storage and simple dissolution, even in a home, the invention enables a wider variety of solution constituents, including reduced acid content and the use of bicarbonate as a stable buffer component. The latter is illustrated in a double-bed embodiment, where bicarbonate is stored separately from calcium or magnesium salts within a single housing.
