Abstract: The present disclosure relates to enhancements in diagnostic assays for detection of analytes. The improved assays are suitable for management of infections and pandemics in humans and animal reservoirs, including but not limited to SARS-CoV-2 (CoV2), and for measurement of biomarkers of disease (both human and veterinary).

Abstract: This invention provides remote audio surveillance by recording audio data via three microphones and storage on a removable digital mass storage device, operating on battery power. The housing is of a weather resistant design to withstand outdoor conditions. Recording can be done in person or recording times can be defined so that the unit will only ‘listen’ during the desired times of the day, on a day to day basis. The user does not have to be in the vicinity but simply programs the record time(s) and leaves the device in the woods. The device also has play back capabilities for any recorded audio data and can interface with personal computers via the removable digital mass storage device. In addition to the audio collection and playback capabilities, PC software will be provided with the device which will analyze the data and provide direction of sound (based upon relative amplitude of the 3 microphones) and distance of sound (based on absolute and relative recorded amplitudes).

Abstract: A gutter guard for preventing the clogging of a gutter includes a spiral member with first and second ends. The spiral member includes a plurality of turns each of which is substantially equal in size and aligned with one another. The spiral member can be moved from a contracted condition to a significantly longer expanded condition. Attached to the top of the spiral member along the length thereof is a mesh screen. The screen has a generally flat appearance when the spiral member is in its expanded condition. A clip secures each of the ends of the spiral member to a corresponding end wall of the gutter.
