Abstract: Disclosed are filtering face masks. The face mask includes a mask body having an upper portion of a first material and configured to cover a user's nostrils: a lower portion of a second material configured to cover the user's mouth; and a divider configured to separate the upper portion and the lower portion. The first material, second material, or both include a filtration material. The face mask may include a sample collection material. The sample collection material may be provided as an insert.

Abstract: Disclosed herein are compositions, devices and methods for detecting analytes in air samples obtained from a subject. Compositions can be included on inanimate surfaces such as masks to be worn by an individual having a test substrate for capturing analytes.

Abstract: Disclosed herein are test substrates, systems and methods for detecting an analyte in a sample. Test substrates of the present disclosure include a predefined pattern, wherein a first region includes a partial pattern of the predefined pattern and a second region that is incomplete and wherein the incomplete portion comprises a reagent that reacts with an analyte in a sample to produce a completed pattern, wherein the completed pattern forms a code.

Abstract: A bio-aerosol collection device for collecting a bio-aerosol sample comprising: a hollow housing comprising an inlet; an outlet; passaging fluidly coupling the inlet and the outlet; and a capture substrate disposed in the passaging downstream of the inlet toward the outlet whereby the bio-aerosol sample contacts the capture substrate as the bio-aerosol sample flows from the inlet toward the outlet.

Abstract: Disclosed are methods for detecting analytes using combined sample collection types. In particular, a first sample is combined with a bio-aerosol sample. Also disclosed are kits that include components for collecting and combining a first sample with a bio-aerosol sample.

Abstract: Systems, methods, apparatuses, and computer readable media are disclosed for improving, in some examples, registration of radio frequency tags with a location system. Example embodiments may include a method for registering a participant with a radio frequency (RF) location tag. The method may include determining tag derived data from the one or more registered RF location tags, identifying at least one unregistered RF location tag, determining an identity of a participant for registration with the unregistered RF location tag based at least in part on the tag derived data from the one or more registered RF location tags, and registering the unregistered RF location tag with the participant.

Abstract: Systems and related methods providing for determining activities of individuals are discussed herein. Circuitry may be configured to wirelessly receive tag signals from a plurality of RF location tags. Two or more of the RF location tags may be positioned on an individual, such as at positions that may at least partially define a human frame. The circuitry may be configured to correlate the two or more RF location tags with the individual. Location data for each of the two or more RF location tags may be determined based on the received tag signals. An activity of the individual may be determined based on the location data. In some embodiments, one or more activities involving multiple individuals may be determined based on RF location tags and sensors positioned on each of the multiple individuals. Furthermore, sensor data from the sensors may be communicated over the UWB channel.

Abstract: Systems, methods, apparatuses, and computer readable media are disclosed for over-determining location estimations for an asset based on location estimates from a plurality of tags. Examples employ a spatial association model in a location system. Examples include a method for processing location information received from a radio frequency (RF) location tag. The method includes determining a first location of a first RF location tag associated with an asset, determining at least one second location of at least one second RF location tag associated with the asset, determining, using a processor, that the first location is not a valid location based at least in part on a comparison of the first location with the at least one second location using a spatial association model associated with the asset, and identifying the first location as erroneous in response to determining that the first location is not a valid location.

Abstract: An audio medium and candle arrangement includes a candle having an outer contour and a first end and a second end. An audio medium is provided having an outer contour which generally corresponds to the outer contour of the candle. The audio medium is positioned adjacent to the candle. The candle enclosure maintains a position of the audio medium relative to the candle. The enclosure may be a tin enclosure with a bottom tin (canister) portion having a candle provided therein and a tin lid for closure of the tin. The tin lid is provided with an inner diameter which is slightly larger than the outer diameter of a compact disc. The inner diameter of the tin lid is provided in a normal way for mating with the tin bottom to close the tin. A compact disc is provided on a compact disc backer or audio medium support, such as a support made of cardboard. Preferably the cardboard backer has a CD center support element for positioning and supporting the CD relative to the backer.
