Abstract: The wearable data collection device includes a processor, a sensor, a digital memory storage, and a battery. There can also be a data transmitter, a data transceiver, and a plurality of switches. The processor, sensor, digital memory storage, and any other electronics can be housed within a sensor module, while the battery is housed within a battery module. The modules are joined to one another to define a sealed unit to be fit in a housing. The housing can be attached by a strap to the user. The switches isolate the battery from the sensor, digital memory storage, the data transmitter, the data transceiver, or other electronic component.

Abstract: In various embodiments, the present disclosure provides a door threshold system that includes a door threshold and a water barrier structured to be disposed along a bottom of the threshold. The water barrier is additionally structured to prevent water from penetrating a joint formed between a bottom of the threshold and a floor structure to which the threshold is mounted.

Abstract: Compositions and methods are provided for producing functional mammalian inward rectifier, G-protein activated potassium channels (Kir3.0 channels). A channel is a multimeric protein comprising one or more Kir3.0 polypeptides, e.g. Kir3.1, Kir3.2, etc., where the polypeptides may be from the same or different species. The functional channel has the distinctive features of an anomalous rectifier, in that it conducts inward but not outward K+ current; it is blocked by low concentrations of extracellular Cs+ or Ba2+; and the conductance of the channel does not depend solely on voltage, but on (E-EK). The ability of the channel to conduct inward K+ current is modulated by G-proteins, particularly G-proteins of the Gi/Go family. A number of mammalian cell surface receptors activate G-proteins as a consequence of specific ligand binding. The signal transduction from receptor to Kir3.0 channel is therefore coupled through G-protein intermediates. The functional Kir3.
