Abstract: A locking cap may be selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap may have a plug portion. A friction load can be used to limit removal of the plug portion.

Abstract: A key retention device and a portable dock for the key retention device are disclosed. The key retention device includes a key holder and a base. The key holder is rotatably coupled to the base. The base includes pins that extend into a cavity of the key holder when the key holder is in a closed position and do not extend into the cavity when the key holder is in an open position. The base includes a finger that prevents users from inserting an electronic key into the key holder when the key holder is in the closed position. The key retention device can receive the portable dock and lock the key holder in the locked position when a user input is received. The user input can be provided to the key retention device to remove an electronic key from the portable dock or to remove the portable dock altogether.

Abstract: Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard cover, a fluid absorber, and a coupling element. The fluid absorber can be configured in a closed configuration to fit at least partially within a cup of a lock face. The coupling element can be configured to couple the guard cover to the lock and can define a second axis. The coupling element can be configured to allow the guard cover to rotate about the second axis.

Abstract: An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry. Audit trail data may be recorded based on usage of the key.

Abstract: Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard head, a guard body, and a hinge. The guard head may include a fluid absorber, a frame that is shaped to receive the fluid absorber, and a fastening mechanism. The guard body can be coupled with an electronic lock. The guard body can include an aperture that is configured to expose a face of the electronic lock.

Abstract: A storage container can include at least one movement sensor in or on a frame of the storage container and at least one movement sensor in or on a door of the storage container. A processor can compare outputs of the movement sensors to determine whether the door is open.
