  • Publication number: 20250067393
    Abstract: Systems, devices, and methods are provided for a two-piece body-worn camera comprising a camera unit that may be docked into a docking unit. The camera unit may be a small form factor capture device that may be mounted to a user's body to capture video. Upon capturing video, the camera unit may be docked with the docking unit for recharging an internal battery and for the transfer of the captured video to the docking unit. Once transferred to the docking unit, the video can be wirelessly transferred to cloud-based storage for long-term storage.

  • Patent number: 4858827
    Abstract: Apparatus for connection with a sill cock for communicating water under pressure from the sill cock with a hose having a lawn sprinkler communicating therewith comprising a water control unit having a female coupler for connection with the sill cock, a male coupler for connection with the hose, a valve between the couplers and a battery operated valve mechanism operable in response to the connection of the electric current thereto for effecting movement of the valve from a closed position into an opened position, and a manually portable programming unit containing a battery operated programming keyboard, a battery operated display, and batteries operatively connected therewith. An extension cord accessory is provided which renders the portable unit operable to operate the water control unit either in its operative position or when the portable unit is disposed in a remote position.

  • Patent number: 4646224
    Abstract: A sprinkler system including a controller having a manual data entry device, a processor and a sprinkler controller. Data is entered through the data entry means relating to conditions in each of a number of zones in which sprinkling is to occur with respect to the amount of water needed to be applied to that zone and the soil water infiltration rate. Upon receiving this information, the processor determines for each zone the number of cycles and the length of time in each cycle that water is to be applied not only so that the amount of water applied during each cycle does not exceed the amount of water the soil can absorb during that cycle, but also so that the total amount of water needed by that zone is applied. The processor employs the number of cycles and the length of on time per cycle to organize the cycles for all of the zones, creating an application program.
