  • Publication number: 20220070666
    Abstract: In one embodiment, a method for secured communication between a medical sensor and a computing device includes receiving, by the medical sensor, an authentication request from the computing device. The method includes generating, based on values provided in the authentication request, a challenge-response message for the computing device. The method includes receiving, from the computing device, a responsive challenge-response message. The method includes verifying that the responsive challenge-response message includes an expected value and corresponds to an expected format. The method includes, in response to verifying the responsive challenge-response message, sending a sensor secret value to the computing device.

  • Patent number: 11134446
    Abstract: Systems, devices and methods are provided for power-efficient wireless communications between electronic devices. In particular, the embodiments disclosed herein can reduce battery consumption in a transmitting electronic device and enhance data integrity of data received by a receiving electronic device. According to the embodiments, a first electronic device transmits advertising packets according to a wireless communications protocol, wherein the advertising packets include a first payload data. In response to receiving the advertising packets, a second electronic device can transmit a scan request to the first electronic device which, in turn, terminates the transmission of advertising packets.

  • Publication number: 20210294736
    Abstract: An application program stored in a ROM includes a function lookup data structure in which functions called by the application program have identifiers and memory addresses at which the function is located and can be executed. Upon startup, the function lookup data structure is copied to a RAM as a revised lookup data structure and is compared to a revision lookup data structure also written to that RAM or elsewhere. If the revision lookup data structure contains replacement functions having the same function identifiers but new memory addresses, these new memory addresses are written over the existing addresses in the revised lookup data structure for those replacement functions. The application program refers to the revised lookup data structure to find and execute the functions; thus the original application program on the ROM can continue to be used with revised functions.
