  • Patent number: 11950167
    Abstract: A mobile computing device can operate as a user device or a service provider device for a network-based service. The mobile computing device can transmit location data to a network system to aid in the network system's management of the network-based service. The mobile computing device can dynamically adjust the location data transmission rate at which location data is transmitted to the network system based on various parameters, including one or more of: a power status, information related to the network-based service, network connectivity metrics, and the like. By dynamically adjusting the location data transmission rate based one or more of these parameters, the mobile computing device can conserve battery power without adversely affecting the provisioning of the network-based service.

Energy consumption of categories of appliances, devices, and equipment is considered a random variable. Using archived energy data, business data, and other related data, statistical modeling is used to create inverse cumulative probability distribution functions. An energy budget (consumption prediction) is computed so that it meets a probability p of the budget being exceeded during a given interval. When the budget is exceeded the feedback is negative, otherwise feedback is positive. Each budget is computed as the value b of the random variable such that the probability that the random variable will be less than or equal to b is 1-p.

  • Patent number: 11496168
    Abstract: A radio frequency circuit includes an amplifier capable of amplifying a first radio frequency signal and a second radio frequency signal that has a frequency different from a frequency of the first radio frequency signal. Here, the amplifier uses a first power-supply voltage to amplify one of the first radio frequency signal and the second radio frequency signal and uses a second power-supply voltage to amplify both the first radio frequency signal and the second radio frequency signal together. A value of the second power-supply voltage is greater than a value of the first power-supply voltage.

  • Patent number: 11477796
    Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.

  • Patent number: 11476817
    Abstract: An active current source load of a fully differential amplifier which is converted into a transconductance (gm) component also at higher frequency by feed-forwarding input signals to their gates. With signal coupling to gate, unity gain bandwidth (UGB) of the amplifier increases by a factor of two. In addition to this, the signal is coupled to source as well to achieve three-fold UGB enhancement. Thus, the effective trans-conductance is gmp at dc and becomes gmp+(gmngate+gmnsrc) at high frequency which triples the UGB when gmp=gmngate/src.

  • Patent number: 11432147
    Abstract: A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID; acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.

  • Patent number: 11397823
    Abstract: A system comprising one or more computers implements a hardware feature access service. The hardware feature access service stores private keys that correspond to digital certificates embedded in chipsets of devices enrolled in the hardware feature access service. The hardware feature access service is configured to issue access or access revocation messages to the chipsets to “lock” or “unlock” associated hardware components. The hardware feature access service also implements a service interface that allows clients to request changes to enabled feature sets for devices enrolled in the hardware feature access service. In response to such requests, the hardware feature service automatically and wirelessly enables or disables feature sets by locking or unlocking relevant hardware components of a device relevant to enabling or disabling the requested feature sets.

    Abstract: A tracking device can be reconfigured after an amount of operation to preserve the battery capacity of the tracking device and to ensure that the tracking device can be operated for a pre-determined threshold period of time. The tracking device can provide diagnostic information representative of a state of the tracking device, such as a current power capacity of the tracking device's battery, to a mobile device within a threshold proximity of the tracking device. The mobile device can then provide the diagnostic information to a tracking server, which in turn can provide reconfiguration instructions to the mobile device. The mobile device can then pass on the reconfiguration instructions to the tracking device, in response to which the tracking device can reconfigure itself.

  • Patent number: 11160017
    Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.
