Abstract: Covers for baby bottles. A baby bottle cover includes an interior space adapted to conform to a baby bottle, an outer surface conforming to the interior space, and at least one opening adapted to receive the baby bottle. The cover may have two openings such that each opening is at opposite ends of the interior space. The interior space may be slightly larger than the baby bottle. The cover may include elastic near the openings, where the elastic forms bands; a liquid level viewing window; and/or one or more flexible materials.

Abstract: Methods and apparatus that implement a transmitter unit and a control unit to alert a user if the control unit is beyond a limited range of communications. A method of alerting a user that a transmitter unit is beyond a limited range of communicating wirelessly with a control unit may include, wirelessly transmitting a radio frequency signal from the transmitter unit to the control unit, determining at the control unit whether the transmitter unit is beyond the limited range of wireless communications, and selectively generating an alert at the control unit based on a result of the determination. Determining at the control unit whether the transmitter unit is beyond the limited range of wireless communications may include detecting an occurrence of a predetermined condition.
