Abstract: A mobile device (e.g., wireless wheeled vehicle) that includes one or more propulsion mechanisms (e.g., one or more drive wheels) and a member (e.g., a mechanized tail). The propulsion mechanism(s) are operable to propel the mobile device across a driving surface. The member is positionable to maintain or change an orientation of the mobile device with respect to the driving surface. The member has a base portion opposite a free end portion. The base portion is pivotably mounted to a portion of the mobile device. The base portion is pivotable to move the free end portion toward and away from the driving surface.

Abstract: A mobile device comprises a platform, a motion drive, and a spatial profiling device. The motion drive is configured to propel the platform according to navigation instructions. The spatial profiling device is configured to capture a spatial profile of a motion area. A spatial profile is received from the spatial profiling device. A mobile object is located employing the spatial profile. A movement is planned for the mobile device between a first location and a second location in the motion area. The movement is configured to avoid the mobile object. The movement is communicated as navigation instructions to the motion drive.

Abstract: A system comprises a mobile device, a spatial profiling device, and a mobile device manager. The mobile device comprises a platform, a first communications circuit that receives navigation instructions, and a motion drive that propels the platform according to the navigation instructions. The spatial profiling device captures a spatial profile of a motion area. The mobile device manager comprises at least one second communications circuit that communicates with the first communications circuit and the spatial profiling device, processor(s), and memory storing processing instructions. The instructions, when executed, cause the mobile device manager to receive spatial profiles, locate the mobile object, locate the mobile device, plan a movement for the mobile device which avoids the mobile object, and communicate the movement to the mobile device as navigation instructions.

Abstract: A clock for the attachment of a dog's collar or the like that indicates the passage of time according to the dog's or pet's frame of reference. For example, the rate of passage of time may be such that for each human day of time passage, seven dog or pet days are reflected by the clock's display. Additional data, displays, and information may be carried, manipulated, entered and chosen by the use of user control buttons or the like. A battery may supply power to internal circuitry that drives a display of liquid crystals (LCD). The data carried by the pet chronometer and identification tag may be held in EEPROM such that a power failure does not erase the data. This is particularly useful for any health data or contact information that is incorporated or recorded into the pet chronometer and identification tag.
