Abstract: The present disclosure relates to a portable insulin and vaccine storage device. The portable insulin and vaccine storage device comprises of a storage unit to store insulin and vaccine; a Peltier module for heating or cooling the storage unit; a heat sink capable of working as a heat exchanger to maintain temperature of the Peltier module; a radiator and fan for maintaining temperature of the storage unit; a control unit for controlling functioning of the portable insulin and vaccine storage device; and a power supply unit for powering the portable insulin and vaccine storage device. The present disclosure provides a device designed to function under extreme weather conditions and being affordable, it is poised to bring about a positive change in the life of people afflicted with diabetes in South Asian countries and those who need to store insulin.

Abstract: One aspect of the present invention can include a dual transmit mobile communication device that includes multiple modems, a modem controller, and a data session manager. The modem controller can programmatically control the modems. The data session manager can manage data sessions of the mobile communication device. The data session manager can programmatically interact with the software modem controller to ensure that only one of the modems is transmitting at any one time. States of data communication sessions can be automatically adjusted as necessary. For example, the modem controller can block transmissions over a data traffic channel in order to use a modem other than one associated with the data traffic channel, such as using a modem to handle a dispatch session. The data session manager can preserve state information of blocked data sessions, so that the sessions can be resumed when a modem is available.
