Abstract: Methods, systems and devices for detecting the presence of a pathogen, for example, a virus (e.g., SARS-CoV-2), or its molecular components, in health care-related samples and/or environmental samples are disclosed. An example system for improving detection of a pathogen includes biosensor device comprising a detection chip and at least one probe that specifically recognizes a pathogen, where the detection chip comprises a graphene field-effect transistor (FET) chip and the probe, which comprises an aptamer, specifically binds to a DNA, RNA, or protein associated with the pathogen.

Abstract: Systems, methods, and other embodiments associated with automatic registration and discovery of services in a network using a platform independent interface are described. In one embodiment, a method includes receiving a request from an event producer on the network to add an entry to a registration table. The example method may also include broadcasting a message to devices on the network to announce the presence of the event producer.

Abstract: Systems, methods, and other embodiments associated with automated upgrade of an operating system are described. In one embodiment, a method includes receiving a request for an upgrade package in a gateway server from a remote device and determining a source location for the upgrade package. The example method may also include sending the request to the source location to cause the source location to provide the upgrade package to the remote device.

Abstract: A method and system for capturing an electronic signature of a user in a Java-based environment on a personal digital assistant. A user is prompted by an applet operating on the personal digital assistant, handling a canvas by the applet, and capturing an instance of the electronic signature on the canvas. The canvas encodes the instance of the electronic signature in a file and transfers the file by the canvas to the applet. A personal digital assistant may include a screen sensitive to pressure for capturing a signature and an application adapted to capture and attach the signature to a business object. The application may also include an applet adapted to prompt a user and adapted to handle a canvas. The canvas is adapted to capture an instance of the electronic signature and encode the instance in a file. The file is transferred by the canvas to the applet.

Abstract: Principles of the present invention provide a method of performing an availability check on a mobile device. The method includes receiving an item number and a requested quantity of the item number. The method creates an availability query with parameters comprising the item number and the quantity, connects to a principal computing platform, and sends the availability query to the principal computing platform. The method receives a query result from the principal computing platform, the query result indicates the availability of the item number at the requested quantity.
