Abstract: Systems, methods, apparatuses, and computer program products for non-invasive glucose monitoring. A method may include continuously capturing a photoplethysmography signal of a patient in real-time. The method may also include inputting a blood pressure measurement, demographic information, and the photoplethysmography signal into a mobile application. The method may further include transmitting, as input information, the blood pressure measurement, the demographic information, and the photoplethysmography signal to a cloud server. In addition, the method may include generating, based on the input information, a glucose prediction of the patient.

Abstract: A system for pandemic and connection tracking is provided. The system includes a memory and one or more processors in communication with the memory, and a data collector executing on the one or more processors. The data collector is configured to collect anonymous tracking data from a wireless sensor network. The wireless sensor network is configured to communicate with users' devices using a wireless connection. The system further includes a data validator/augmentor executing on the one or more processors. The data validator/augmentor is configured to validate the collected anonymous tracking data. The system also includes a virus spread tracker executing on the one or more processors. The virus spread tracker is configured to: estimate an exposure time between each pair of users based on the collected anonymous tracking data; and determine a probability of at least one of the users being infected based on the estimated exposure time.

Abstract: Systems, methods, apparatuses, and computer program products for backscatter RFID communication security. In some example embodiments, a system may include a RFID reader, and a passive RFID tag. A desired direction channel H?R between the RFID reader and the passive RFID tag is H?R=[ej2? cos ?R ej? cos ?R e?j? cos ?R e?j2? cos ?R]. In certain example embodiments, a system includes a first RFID reader, a second RFID reader, and a passive RFID tag. The first RFID reader is aware of the location of the second RFID reader and the location of the passive RFID tag. The second RFID reader is aware of the location of the first RFID reader and the location of the passive RFID tag. The first RFID reader and the second RFID reader are aware of each others generated reader signals.
