Patent number: 10957968Abstract: A method, wireless communication device (WCD), and computer program product deploys an additional, retractable antenna to enhance signal communication within an identified network. A processor executes an antenna deployment module (ADM) in order to determine a link status based on a quality and/or a strength of communication signals propagated via at least one stationary antenna. In response to the link status indicating that coverage of a second/target network is available or that a quality of a signal propagated within a first network is less than a threshold level, the ADM provides a deployment signal to a deployment component. In response to receiving the deployment signal, the deployment component deploys the retractable antenna by extending the retractable antenna from a stowed position to a deployed position. The ADM enables the WCD to communicate within the selected network via the deployed retractable antenna using a higher quality communication signal.Type: GrantFiled: November 20, 2018Date of Patent: March 23, 2021Assignee: Motorola Mobility LLCInventors: Md Rashidul Islam, Mohammed R.

Patent number: 10938975Abstract: A calling user initiates a telephonic communication with a receiving user by dialing a phone number of the receiving user in his or her address book. The communication is transmitted from the calling user's device to the receiving user's device through a network that is not using Internet protocol or Internet-based, e.g., Transmission Control Protocol (TCP), Internet Protocol (IP), TCP-IP, or Voice over Internet Protocol (VoIP). After a number of notifications has passed on the receiving user's device and the receiving user is not able to answer the telephonic communication, a local voicemail recorder will be activated to record and store the telephonic communication for later retrieval by the receiving user. The stored communication is identifier by a sequence of string containing at least one of a name, a telephone number, a storage location, a date-time attribute, and a duration associated with the stored communication.Type: GrantFiled: December 25, 2017Date of Patent: March 2, 2021Inventors: Chi Luu Ngoc Nguyen, Chuong Luu Thanh Nguyen

Patent number: 10931712Abstract: A method and associated circuits protect data stored in a secure data circuit of a telecommunication device equipped with a near-field communication (NFC) router, a microcontroller, and the secure data circuit. In the method, each message received with the NFC router is parsed to retrieve a communication pipe identifier and an instruction code. The communication pipe identifier and the instruction code are compared to corresponding information in a filter table. Instruction codes of particular messages that attempt to modify a communication pipe by reassigning one end of the communication pipe from the port of the NFC router to a different circuit are acted upon. These messages are blocked from reaching the secure data circuit when the instruction code is not authorized in the filter table, and these messages are permitted when the instruction code is authorized in the filter table.Type: GrantFiled: November 27, 2019Date of Patent: February 23, 2021Assignees: STMICROELECTRONICS (ROUSSET) SAS, PROTON WORLD INTERNATIONAL N.V.Inventors: Thierry Huque, Olivier Van Nieuwenhuyze, Alexandre Charles
