  • Patent number: 11574224
    Abstract: Internet-of-things (IOT) devices can be identified based on specific behavioral patterns when their identification data is unknown. Previously identified IOT devices with similar behavioral patterns can be used as a baseline from which to compare data that is available about unknown IOT devices. For example, an IOT device can be pooled with a group of IOT devices based on the frequency with which they connect to a wireless network. Additionally, a confidence level of the unknown device being associated with the group of IOT devices can be generated based on such comparison data.

  • Publication number: 20220329989
    Abstract: A lightweight machine-to-machine (LWM2M) protocol can be utilized as a management layer for other applications pertaining to communication and retrieval of information from hardware peripherals. The applications can be managed via a client and the applications can communicate to the client via a standard proxy or message broker. Consequently, sensor codes can be decoupled from the client codes, thus allowing them to both be independent interchangeable components of a specific device's architecture. Therefore, sensors can be added, removed, and/or manipulated without modifying the underlying management layer.

  • Patent number: 10587626
    Abstract: An aspect includes storing data elements in a storage space of a memory device. The storage space is allocated for an account of a subscriber of a universal subscriber identification system. An aspect also includes assigning subscriber-inputted security levels to the data elements. The security levels define varying degrees of access protections associated with the data elements. An aspect further includes generating a security envelope that includes a data element selected from the storage space. The security envelope is configured with an access protection scheme that is commensurate with a corresponding assigned security level. An aspect also includes providing access to the selected data element by another subscriber of the universal subscriber identification system via the security envelope. The access is provided in accordance with the access protection scheme.

  • Patent number: 9513776
    Abstract: A system for providing wireless control of a visual aid based on movement detection is disclosed. The system also enables a presenter to gesture at a visual aid and have a pointer be displayed on screens displaying the visual aid. The system may generate a three-dimensional depth image of an environment including a user and a device displaying the visual aid. Additionally, the system may determine a position of the user relative to the environment and to the device based on the three-dimensional image. Furthermore, the system may detect a gesture based on the position of the user and the three-dimensional depth image. If the gesture made by the user matches a predetermined input gesture corresponding to a controller operation for controlling the visual aid, then the controller operation may be executed. The system may display an output of the executed controller operation at a remote device.

  • Patent number: 7983707
    Abstract: A push-to-talk communications device (PCD) provides improved push-to-talk (PTT) communications. The PCD may include a PTT activator and a PTT module having a buffer and communications logic for providing full duplex PTT communications. In a Point-to-Point PTT mode of operation, PTT communications are performed between two PCDs with the PCDs exercising floor control. After the establishment of communications between the PCDs, the PCDs may enter a PTT talk mode wherein messages are transmitted between the PCDs in real time when a PTT activator is engaged. A PCD may also enter a group PTT mode wherein a PTT server exercises floor control between an initiating PCD and multiple target PCDs.

  • Patent number: 6405038
    Abstract: A method and an apparatus for selecting a cellular carrier frequency for accessing cellular airtime services based upon a list of preferred system identification codes (SIDs). A cellular telephone is programmed to accept into memory a list of preferred SIDs corresponding to carriers through which service is preferred. While any SID remains in a preferred list, the standard A/B system selection function is replaced by a substitute system selection function which includes only three carrier selection modes including the Home Only mode, the SID Only mode, and a Roam Saver mode. With the Roam Saver carrier selection mode, the cellular telephone first prefers service through a home carrier and then through a carrier broadcasting a SID matching a SID on the preferred list, but never denies service to emergency or non-emergency destinations if any SID is detected.

  • Patent number: 6400948
    Abstract: A radiotelephone system having DCCH channels includes an over-the-air activation teleservice sub-system (OTAF) for programming mobile stations (MS) with Intelligent Roaming (IR) information. Each MS includes a history list containing the most recently used DCCHs. The IR information sent to a MS includes data for setting the number of entries in the history list, data for setting the content of the history list entries, and a data for setting the power level threshold. The number of entries in each MS can be optimally set according to the number of DCCHs in a network with networks having a greater number of DCCHs being able to place a greater number of entries in the history list of their subscribing MSs. The content of the history list, moreover, may be optimally set for a network and for a particular cell or group of cells in a network. Thus, for instance, an MS entering a new network can be programmed to have the DCCHs of the new network. The power level threshold is used by the MS to detect suitable DCCHs.
