Abstract: An example monitoring device for a steam trap includes: an enclosure; a sensor subsystem housed in the enclosure, the sensor subsystem to measure a property of the steam trap; a memory housed in the enclosure; a communications interface housed in the enclosure and configured to communicate with a server; a processor housed in the enclosure and interconnected to the sensor subsystem, the memory, and the communications interface, the processor configured to: obtain, from the sensor subsystem, data representing the property of the steam trap; extract a set of key features from the data; and send, via the communications interface, the set of key features to the server for further processing to detect a failure.

Abstract: An ultra-low sensitivity ground fault circuit interrupter (GFCI) device and a method for manufacturing the device is disclosed. The GFCI device detects an unbalanced current between line and return conductors that results from an unintended path to ground. The GFCI device disconnects the current source when a leakage current is detected. The GFCI device includes a current transformer that has its core wrapped with the line and return conductors. The line and return conductors are secured around the core in a fixed position. During manufacture of the GFCI device an amplifier of the GFCI can be adjusted so that the GFCI device disconnects the current source when a leakage current exceeds a desired level.

Abstract: The invention provides apparatus for conditioning organic fluid for subsequent use in a medical procedure. The apparatus includes a cabinet having a secure environment and a door providing the only access to the environment. An input system is provided for transporting a organic fluid charge from a source to the cabinet and a container is removably contained in the secure environment and coupled to the charge input system to receive the charge. Stressors are coupled to the cabinet and positioned for operation to create a conditioned charge in the container An output system is coupled to the container and includes a receiver for the conditioned charge. The apparatus also includes a needle hub wherein a first end of the needle may be inserted intramuscularly while a second end of the needle projects beyond the patient's tissue and the second end being shielded.
