Abstract: A saliva-based testing method that bypasses the need for RNA isolation/purification is described herein. In experiments with inactivated SARS-CoV-2 virus spiked into saliva, this method has a limit of detection of 500-1000 viral particles per mL, rivalling the standard NP swab method. Initial studies showed excellent performance with 100 clinical samples. This saliva-based process is operationally simple, utilizes readily available materials, and can be easily implemented by existing testing sites thus allowing for high-throughput, rapid, and repeat testing of large populations.

Abstract: The present disclosure generally relates to displaying information related to a physical activity. In some embodiments, methods and user interfaces for managing the display of information related to a physical activity are described.

Abstract: A Tee-nut having a flange head, a plurality of prongs extending from the flange head, and a hollow sleeve extending from the flange head. The hollow sleeve has an internally threaded reduced diameter waist portion connecting to the flange head, and an enlarged globular bulbous portion extending from the internally threaded waist portion. The end of the enlarged bulbous portion is radiussed inwardly to facilitate insertion into a hole in a workpiece. Also disclosed is a workpiece fitted with such a Tee-nut.

Abstract: An evacuated testing device (100) including a housing (106) providing a test chamber (101) therein, a first mechanism (102) for retaining an object (116) under test in relation to an aperture (112), a second mechanism (104) positioned within the test chamber (101) for generating and transmitting uniform electromagnetic radiation to the object (116), and a third mechanism (122) disposed within the test chamber (101) in thermal communication with the second mechanism (104) for varying the temperature thereof. In a preferred embodiment, a test dewar (102) and an infrared blackbody radiating source (104) are enclosed within a test chamber (101) of the evacuated testing device (100). A focal plane array (116) is mounted on a cold finger (114) within the test dewar (102) in close proximity to an emissive surface (126) of the blackbody radiating source (104). A thermoelectric cooler (122) varies the temperature of the emissive surface (126) which generates and transmits the infrared radiation.

Abstract: A vehicle lamp assembly comprises a housing adapted to be affixed to a vehicle, a lamp component adapted to be mounted in the housing, and means for rigidly retaining the lamp component in the housing without the use of conventional threaded fasteners. The securing means comprises a resilient tab extending away from the lamp component which engages a retainer affixed to the housing, to rigidly maintain the lamp component in the housing.

Abstract: A new, high-impact capacity bearing for rotatively supporting a load for rotation about the bearing axis. The bearing comprises inner and outer members having respective inner and outer raceways shaped so that each provides a multi-point contact with the bearing elements which travel in the raceways. A novel wheel construction incorporating the bearing assembly is also disclosed. This construction provides reduce impact loading on the bearing assembly thereby increasing the load and impact capacity of the wheel construction. The wheel construction is admirably suited for use in the lift of a fork lift truck.
