Title: Deployable monitoring device having self-righting housing and associated method
Inventor: GRAINGER WILLIAM
IPC: H04N7/18
Filed: 2002-07-11
Abstract: A deployable monitoring apparatus is provided comprising an ovate housing and a video capturing device operably engaged therewith. The housing has a base and an opposed end disposed along an axis. The housing is further configured to have a center of gravity disposed about the base so as to be self-righting along the axis such that the opposed end extends substantially upwardly from the base. The video capturing device is operably engaged with the housing and is configured to capture video data of a scene external to the housing. In some instances, the video data of the scene may be transmitted by a transceiver module to a station disposed remotely from the scene, wherein the station is configured to process the video data so as to provide a remote visual depiction of the scene. The housing may also include other devices such as, for example, a light source, a motion sensor, an audio sensor, and a chemical sensor functioning independently of or in conjuction with the video capturing device. An associated method is also provided.
