Abstract: A disclosed wireless tunneling system tunnels communications between two processing apparatuses through a wireless link, while maintaining compliance of the communications between the two processing apparatuses with at least two different wired communication protocols. In one embodiment, the wireless tunneling system includes two wireless tunneling apparatuses that communicate with each other through the wireless link. A local wireless tunneling apparatus is coupled to a local processing apparatus through a wired connection and a remote wireless tunneling apparatus is coupled to the remote processing apparatus through another wired connection. The two processing apparatuses may communicate with each other through the wireless link using the two wireless tunneling apparatuses as if the two processing apparatuses were connected through wired connections.

Abstract: A device for immunochromatographic assay includes a housing and a vessel body. The housing has an upwardly-extending hollow protrusion for housing the vessel body. The vessel body has a vessel body wall and a vessel body bottom. A raised tip and a fence surrounding the tip are arranged in the housing. The vessel body and the raised tip can be moved towards each other such that the raised tip can break the vessel body bottom to release liquid in the vessel body.

Abstract: The present disclosure provides for improving security in a meter or an intelligent electronic device (IED) through the use of a security key which is unique to each meter or IED. Such a key may be used to prevent password reuse among multiple meters. Such a key may also be used to encrypt critical components of the software, such that only when running on the correct meter can the components of the software be decrypted. Such a key may also be used to uniquely identify the device in a larger data collection and management system. The security key can also be used to prevent the direct copying of meters. The present disclosure also provides for a meter or IED that stores functional software separately from core software.

Abstract: An intelligent electronic device (IED) is provided. The IED includes a metering sub-assembly and an input base module sub-assembly. The metering sub-assembly is hinged to the input base module sub-assembly, where when in an open position, various cables, connectors, and input/output cards/modules are accessible. Various input/output cards/modules are interchangeable to add/change functionality and/or communication capabilities to the IED.
