Abstract: The system contains a motion sensor. In one embodiment a clock is in communication with the motion sensor. A processor is in communication with the motion sensor and the clock. The processor records a volume of motion sensed by the motion sensor as a function of time received in communications from the clock. An output device has a plurality of output signals. A plurality of threshold values stored in a memory is correlated with the output signals. A comparator is in communication with the output device, the memory, and the processor. The comparator compares the processor recordings to the threshold values stored in memory and initiates one of the plurality of output signals when the processor recordings exceed at least one of the threshold values.

Abstract: A new and useful barrier device for a utility system cover is provided. The barrier device is designed to be coupled to a utility system cover (e.g. a water meter cover), in a way that effectively seals the opening in the cover against ingress of dirt, debris, animals, etc. Moreover, the barrier device also provides a structure that enables a hook like tool to engage and manipulate the coupled barrier device and cover, while maintaining the barrier against ingress of dirt, debris, animals, etc. The barrier device includes a hood with a border that at least partially flattens against a utility system cover as the baffler device is coupled to the utility system cover, so that the border of the hood and the utility system cover combine to form a baffler to materials and objects near the border of the hood. A stem extends from the hood, and is pressed into the utility system cover, in a way that effectively couples the baffler device with the cover.

Abstract: A new and useful barrier device for a fluid system cover is provided. A preferred version of the barrier device comprises a one piece cap structure designed to be coupled to a fluid system cover (e.g. a water meter cover), in a way that effectively seals the opening in the cover against ingress of dirt, debris, animals, etc. Moreover, the present invention provides a barrier device that, in its preferred form, also provides a structure that enables a hook like tool to engage and manipulate the coupled barrier device and cover, while maintaining the barrier against ingress of dirt, debris, animals, etc. The one piece barrier device includes a hood with a border configured to at least partially flatten against a fluid system cover as the one piece structure is being coupled to the fluid system cover, so that the border of the hood and the fluid system cover combine to form a barrier to materials and objects near the border of the hood.
