Abstract: The present disclosure provides a method of testing a subject for COVID-19, the method comprising the steps of: obtaining a saliva sample from the subject; diluting the saliva sample with a dilution buffer comprising a base; contacting the diluted saliva sample with one or more loop-mediated isothermal amplification (LAMP) primers that bind regions in the N gene of the SARS-CoV-2 virus to form a test mixture; and analyzing the color of the test mixture. The present disclosure also provides a COVID-19 rapid-test kit comprising one or more components for the collection of a saliva sample from a subject, one or more components for processing of the saliva sample, and one or more components used to interpret the results of the COVID-19 test.

Abstract: An electronic device including a button assembly is provided. The electronic device includes a housing, a button member which is at least partially exposed to the outside of the housing, a substrate portion disposed in an inner space of the housing, a dome switch module mounted on the substrate portion, a bracket mounted inside the housing, and a block member which is disposed between the dome switch module and the bracket and includes a base portion coupled to one surface of the bracket, a contact portion in contact with the dome switch module, and a support portion disposed on the periphery the contact portion.

Abstract: A storage device that maps logical addresses to physical addresses includes a memory that stores machine instructions and a processor coupled to the memory that executes the machine instructions to store a compressed mapping table in the memory. The compressed mapping table correlates logical addresses to locations in a storage. The storage device also stores a bundle of uncompressed mapping table entries starting at a first location in a cache and maps a first logical address associated with the uncompressed mapping table entry to the first location.

Abstract: Disclosed is a method of and apparatus employing the method for automatically enabling long-distance calls on the land-line public telephone switched network and debiting the wireless subscriber's account an amount for the long-distance call. The method includes the steps of providing a predetermined telephone number having means for answering the call; answering the call, receiving a password entered by a user; comparing the entered password to a stored password to enable access to the landline public telephone switched system. The method also includes accepting a long-distance telephone number to be called, initiating a call on the land-line network at the entered long-distance telephone number. If the receiving instrument answers, the call is timed. Upon termination of the call, data is stored corresponding to the elapsed time of the call and the subscriber's account is debited an amount for the call.
