Abstract: This disclosure relates to coronavirus assays, diagnostic methods, treatment methods, and compositions related thereto. In certain embodiments, this disclosure relates to ACE2 receptor binding domain peptides and uses in serological assays and vaccination methods.

Abstract: An immunological or immunohematological assay system is disclosed that includes a filter vessel capable of containing an assay sample, an incubator, a sample separation system, an image acquisition system, and a robotic pipettor. The immunological assay system may also include a washer. Also disclosed is an immunological assay method that includes the steps of placing a immunological assay sample in a filter vessel, which includes a filter, adding testing reagents to the filter vessel, incubating the sample and reagent mixture in the filter vessel, separating the sample and reagent mixture in the filter vessel into components above and below the filter, and analyzing the filter vessel to determine the presence of interactions between the sample and reagents.

Abstract: The present invention provides a method of transplanting hematopoietic cells between genetically unrelated individuals, comprising administering to the recipient, in combination with the administration of the hematopoietic cells, an amount of mononuclear cells which are treated so as to substantially reduce their ability to cause graft versus host disease while they retain their ability to proliferate in the recipient. The treated mononuclear cells can facilitate engraftment of hematopoietic cells when transplanted in combination with hematopoietic cells, treat or prevent infections, and treat cancer.

Abstract: An antenna detent and latching mechanism (300) for coupling to a radiotelephone and mating with a radiotelephone antenna stem (200) is provided. The antenna detent and latching mechanism (300) includes a bottom plate (380) for mounting the mechanism in the radiotelephone, a bearing plate (360) coupled to the bottom plate, a detent follower (373) coupled to the bearing plate (360) and engaging a plurality of detents (366, 368, 370) in the bearing plate (360), and a detent spring (374) coupled to the detent follower (373) and providing force against the detent follower (373). The detent spring (374) is preferably a substantially flat leaf spring. The detent follower (373) preferably has a plurality of detent spring contact surfaces (377, 378). The detent spring (374) may be supplemented with additional detent springs (375).

Abstract: An antenna detent and latching mechanism for use in a radiotelephone to provide a robust connection of an antenna to the radiotelephone. When the mechanism and antenna are coupled, the antenna can be rotated from a stored position to one of two deployed positions.

Abstract: A battery (105) includes a battery housing (340) having a latching mechanism (301) for attaching to a radiotelephone body (102). The latching mechanism (301) includes a button portion (405), a first torsion plate (403), a second torsion plate (404), and a catch (401). The battery housing (340) further includes an inner surface (400), a first rib (630), and a second rib (632). The first and second ribs (630, 632) extend upwardly from the inner surface (400) and attach respectively to the first and second torsion plates (403, 404), thereby supporting the latching mechanism (301) at a distance above the inner surface (400). The first and second torsion plates (403, 404), while providing a torsional twisting movement for detaching the battery (105) from the radiotelephone body (102), provide a strong deflection resistance for the latching mechanism (301).
