Fluidic connectors, methods, and devices for performing analyses (e.g., immunoassays) in microfluidic systems are provided. In some embodiments, a fluidic connector having a fluid path is used to connect two independent channels formed in a substrate so as to allow fluid communication between the two independent channels. One or both of the independent channels may be pre-filled with reagents (e.g., antibody solutions, washing buffers and amplification reagents), which can be used to perform the analysis. These reagents may be stored in the channels of the substrate for long periods amounts of time (e.g., 1 year) prior to use. Prior to connection of the fluid connector and the substrate, the fluid path may be filled with a sample (e.g., blood). The sample may be obtained, for example, by pricking a finger of a user until blood is drawn from the finger into the fluid path (e.g., by capillary forces). Upon connection of the fluidic connector and the channels of the substrate, the sample can pass through a reaction area within the first channel of the substrate. This process can allow components of the sample to interact with components disposed in the reaction area. Afterwards, reagents from the second channel can flow to the reaction area via the fluid path, allowing components in the reaction area to be processed (e.g., amplified to produce detectable signal). Components in the reaction area can then be determined using various methods of detection.

Channel scanning for wireless networks, such as Wireless Local Area Networks (WLANs), generally provides a wireless station with the information on the available WLAN resources, such as the frequency band and the maximum transmission power. The present invention provides safe and fast domain-aware channel scanning, enabling a wireless station to comply with applicable local regulations, in spite of the possibility of domain changes, with short channel-scanning time. Fast channel scanning is accomplished by active channel scanning if valid domain information is available and there is no possibility of domain change. Also, domain-independent channels, if any, are first scanned using active scan to get domain information faster.

A PC-based ECG software program that in real time, acquires, analyzes and displays QTV and PQ interval variability (PQV) in each of the independent channels that constitute the 12-lead conventional and / or Frank X, Y, Z lead ECG. The system also analyzes and displays the QTV and PQV from QT and PQ interval signals that are derived from multiple channels and from singular value decomposition such that the effect of noise and other artifacts on the QTV and PQV results are substantially reduced compared to existing single-channel methods. Moreover, this invention also provides certain new parameters of T-wave (and QRS and P-wave) morphology, that in initial studies have improved clinical diagnostic utility and / or reproducibility and reliability compared to known existing parameters of T-wave morphology. Finally, it also provides a method for determining the beat-to-beat variability these T, QRS and P-wave morphologic parameters.
