Abstract: The present disclosure is directed to a system for improving the security of cellular-enabled blood glucose data transmission by layering security, the system comprising: an apparatus; a wireless network; a private network connected via a persistent IPsec VPN tunnel; one or more computer processors; and a memory with instructions that cause the system to: collect initial blood glucose data from a patient; encrypt the data with a shared secret; generate a first hash using a signing algorithm; transmit the encrypted data via the IPsec VPN tunnel to the private network; generate a second hash; compare the first hash to the second hash; decrypt the encrypted data upon a match, creating verified blood glucose data; and transmit the verified data to a target recipient.

Abstract: A system for improving patient data transmission security comprising: a medical device; a wireless network connected to the medical device; a private network connected to the wireless network via an IPsec VPN tunnel; one or more computer processors; and a memory storing machine executable instructions, that when executed, cause the system to: receive, a patient interaction, the patient interaction including a medium from which raw patient data is collected; encrypt, v the raw patient data with a shared secret, creating encrypted patient data; generate, a first hash using a signing algorithm; transmit, the encrypted patient data from the medical device to the private network; generate, a second hash; compare, the first hash to the second hash; decrypt, the encrypted patient data upon a match of the first and second hash, creating verified patient data; and transmit, the verified patient data to a target recipient.

Abstract: A smartphone-operated HVAC airflow anemometer device and system includes an anemometer device having an impeller and a photo interrupter circuit. The circuit generates an output signal that is proportional to the rotation speed of the impeller, and transmits the same via a headphone jack to a smartphone device running an airflow balancing application. The airflow balancing application receives airflow data from the anemometer and provides power to the same. The application can apply one or more algorithms to the received airflow data to generate airflow information which can be stored or transmitted by the smartphone device.

Abstract: A smartphone-operated wireless HVAC airflow anemometer device and system includes an anemometer device having an impeller assembly, an inductor and a controller. A magnet within the impeller assembly generates an oscillating current in the inductor which is proportional to the rotational rate of the impeller. A controller captures and transmits this information wirelessly to an airflow balancing application located on a smartphone device that includes a plurality of algorithms for calculating airflow information. An environmental sensor unit, and an electronic compass are also located within the wireless anemometer device.
