  • Patent number: 10938855
    Abstract: Systems and methods for computer network infrastructure provisioning are provided. In one illustrative implementation, a base server is sent to and physically installed at a remote site by field technicians, the base server automatically and securely connects back to a central site, and then becomes the platform to logically provision all other network elements to start a remote network infrastructure, wherein this process may be accomplished without intervention by network engineers at the remote site. The connection and communication between the central and remote site can be implemented over various networks, such as over the Internet, over a private IP network, over a cellular network, and/or other networks. According to implementations herein, the base server can ensure physical and logical integrity even if the environment or the chain of custody of the equipment involved is not trusted.

  • Patent number: 10704960
    Abstract: Embodiments of an environmental monitoring system that mitigates complexities in installation and maintenance while complying with strict regulations on operations of the system. The environmental monitoring system may communicate wirelessly between components such as sensor units and display devices, enabling these components to be separately and easily installed in an environment without needing to install wires in the environment to connect them. In addition, in embodiments at least some of the components (e.g., sensor units and display devices) of the environmental monitoring system may be adapted to wirelessly and reliably communicate using specific wireless communication protocols, described in detail herein, that exchange few communications between the components and thereby decrease power consumption of these components. Further, in some embodiments, a display device may include hardware and/or execute software that drive and/or update a display only when a condition is met.

  • Patent number: 10466994
    Abstract: Methods and systems for wireless firmware upgrades are provided. In one embodiment, a system comprises: at least one master source radio and one or more client radio devices in wireless communication with the master source radio. The master source radio transmits a firmware image block broadcast to the client radio devices comprising sequentially transmitted firmware image blocks, wherein the master source radio transmits each block a plurality of times. Each of the plurality of sequentially transmitted firmware image blocks is transmitted as payload within a broadcast block, the broadcast block further comprising metadata associated with the payload. The client radio devices each include a firmware memory and a boot loader. The boot loader assembles a firmware image from the firmware image block broadcast and stores the firmware image into the memory. Transmission of the firmware image block broadcast is not controlled using feedback from the client radio devices.

  • Patent number: 10401237
    Abstract: Embodiments of a certification system for use with an environmental monitoring system that may monitor environmental parameters of multiple different environments. The certification system, which includes one or more computing devices, monitors the certification of environmental sensors of the system. When the certification system detects that the certification of a sensor in a first environment satisfies a condition, such as that the certification is to expire within a threshold period of time, the system triggers the distribution of a certified sensor to an operator of the first environment to replace the sensor for which the certification is to expire. For example, the system may trigger the environmental monitoring system to send a newly-certified sensor to the first operator of the first environment.

  • Patent number: 10190790
    Abstract: A thermostat method and apparatus has one or more demand circuits, an energy storage device; a DC regulator connected to the energy storage device, and a thermostat control connected to the DC regulator and to the energy storage device. Current is drawn from the one or more demand circuits when demand associated with the demand circuits is not active and the energy storage device is charged with the current drawn from the one or more demand circuits. If energy stored in the energy storage device is below the first predetermined threshold, activity in the thermostat is reduced and if energy stored in the energy storage device is above the second predetermined threshold, activity in the thermostat is allowed to increase.

  • Patent number: 10057859
    Abstract: Devices, systems, and techniques for a synchronized network for battery backup are described herein. A network device can establish a synchronized sleep schedule with the network while in a mains-power mode of operation. The network device can transmit data in the mains-power mode without regard for a transmission window of the synchronized sleep schedule. The network device can detect an interruption of mains power to itself and transition to a low-power mode of operation. The network device can then transmit data in the low-power mode, restricting data transmission to the transmission window of the synchronized sleep schedule.
