Abstract: An antimicrobial composition for treating plant diseases includes oxytetracycline (OTC) and an acid substantially dissolved in water to generate an OTC solution having a pH in a range of 1.8 to 2.5 and a concentration of the oxytetracycline sufficient to treat a bacterial infection in a plant. The OTC or the salt thereof has a purity sufficient to generate an OTC solution that is substantially stable for a time period required for its delivery to a plant. The OTC solution can be delivered systemically to a plant to treat a bacterial disease inflicting the plant.

The memory is in electronic communication with the microprocessor. The wireless communication device is configured to receive a wireless signal which wirelessly controls the disposable electronically controlled medication pumping system.

Abstract: An antimicrobial composition for treating plant diseases includes a solvent into which an antibiotic is substantially dissolved to achieve a concentration of the antibiotic sufficient to treat a bacterial infection in a plant. An acid is added to the solvent at a concentration sufficient to generate a pH in a range of 1.5 to less than 4.0. The antimicrobial can be delivered systemically to a plant, thereby allowing the antibiotic to treat a bacterial disease inflicting the plant.

Abstract: Methods, systems, apparatuses, and computer-readable media for updating an operational parameter of a device of a local network of interconnected devices are provided. A user-operated device, in association with an attempt to access the device, may provide an update to the operational parameter of the device. The user-operated device may send the update to the operational parameter before sending the device an operational command. The device may apply the update received from the user-operated device before performing an operation corresponding to the operational command.

Abstract: A tree injection assembly and method includes fluidly coupling a source of pressurized liquid to a chamber. The chamber is comprised of a resiliently elastic perimeter wall and the chamber is inflated with a predetermined amount of the pressurized liquid. After being the chamber is inflated with the pressurized liquid, the perimeter wall exerts pressure on the pressurized liquid. An injection nozzle, fluidly coupled to the chamber with a conduit, is inserted into a borehole formed in a tree. The chamber is allowed to deflate to force the liquid into the tree through the borehole.

Abstract: An access control system may be deployed at a location in a multi-tenant environment. The access control system may store access control information at one or more of an access control device, an access control bridge device, or an access control server. Tenant-specific access control information may be respectively stored at tenant-specific access control devices to control access to tenant-specific areas of the location. Shared access control information may be stored at shared access control devices to control access to common areas of the location. The access control system may be selectively configured such that an access device, an access control bridge device, or the access control server processes requests for access that are received at the location.

Abstract: Systems, methods, and devices are described herein for executing a lockdown of electronic locks deployed in a local network of interconnected devices. In example implementations, each electronic lock is provided with a unique encryption key specific to that electronic lock and is provided with a shared encryption key. To execute a lockdown of all electronic locks in the local network, a server generates a locking instruction and encrypts it using the shared encryption key. The server then transmits the encrypted locking instruction to the gateway devices of the local network which, in turn, transmit it to each of the electronic locks. Upon receipt of the encrypted locking instruction, the electronic locks attempt to decrypt it using the shared encryption key. Upon successful decryption of the encrypted locking instruction, an electronic lock toggles to a lock state.

Abstract: Systems, methods, and apparatus for using a message broker that implements a publish-subscribe messaging protocol to exchange messages between a remote server and a bridge computing device of a local network of interconnected devices are disclosed. In one example, a bridge computing devices transmits to a remote server, a provisioning request in response to achieving a power-on state. The server generates and transmits, to the bridge computing device, a provisioning response that includes information indicating a channel to which the remote server will publish messages and a channel to which the bridge computing device should publish messages. The bridge computing device subscribes to the channel the server will publish to, and the server subscribes to the channel the bridge computing device will publish to. Third-party computing devices may also subscribe and publish to the channels in order to receive and provide messages to the bridge computing device.
