Title: Tamper-indicating closure with resilient locking projections
Inventor: MCNARY DREW H
IPC: B65D41/34
Filed: 2001-09-06
Granted: 2005-08-23
Abstract: A method for manufacturing a tamper-indicating closure having a plurality of resilient flexible projections bent upwardly and radially inwardly at a predetermined radius of curvature. The first step in the method includes providing a mold assembly comprising a female mold portion for forming the outer surface of the closure and a male mold portion for forming the closure's inner surface and its plurality of projections. The male and female mold portions are arranged for relative movement toward and away from each other between a mold open position and a mold closed position. When in the mold closed position, the male and female mold portions define a mold cavity in which the tamper-indicating closure is molded. The next steps in the method are to move the male and female mold portions into the mold closed position; to provide a mold material into the mold cavity; and, to maintained the mold portions in the mold closed position for a predetermined time period until the tamper-indicating closure is formed with its projections disposed at their predetermined radius of curvature.  Next, the male mold portion is removed from the molded closure, whereby the projections temporarily bend from their predetermined radius of curvature to a second position. The closure includes a plurality of strain relief recesses corresponding to the number of projections, each strain relief recess being located radially outwardly from each projection. Each recess, in combination with the predetermined radius of curvature, acting to limit the extent of deformation of the corresponding projection during removal of the male mold portion so the projection can elastically return to substantially its "as molded" configuration.

Title: Apparatus for detecting enuresis in a patient
Inventor: SMITH TOBY E
IPC: A61F13/42
Filed: 2000-07-21
Granted: 2007-03-20
Abstract: This invention relates generally to patient monitoring systems and more particularly concerns devices and systems used to monitor bed patients in hospital or other care-giving environments. In accordance with a first aspec t of the instant invention, there is provided a wetness detector for use in patient monitoring situations and which is adjustable in its degree of sensitivity to wetness. It contains at least two conductive regions (130, 14 0) placed on a non-conductive base (120) and which are preferably separated laterally by some distance. Isolated electrical leads (145) are attached to each conductive region (130, 140). Electrical current passes much more readi ly between the two conductive regions (130, 140) when an electrolytic solution such as urine is present within the switch, thereby making it possible for a separate electronic monitor to determine when wetness is detected.

Abstract: A leak in a fuel cell module (1) can allow hydrogen (H2) and/or oxygen (O2) to escape from the fuel cell module (1), hereby creating a high risk of fire or explosion. The invention address es this problem by providing a fuel cell installation with a fuel cell module (1) that is enclosed in a gas-tight pressure container (3). Filling the pressure container (3) with a protective gas ensures that if the fuel cell module (1) does leak, no operating gas can escape from the module (1), protective gas entering the module (1) instead. A leak therefore no longer poses a risk. The leak can also be identified and located by a voltage drop in the cells affected by the leak.
