Abstract: An apparatus for releasably securing a mattress cover or bedclothes to a mattress or bed, including a generally rectangular anchoring device to be positioned below the sleeping surface of the mattress, and fastening members for connecting the anchoring device to a mattress cover or other bedclothes. Each fastening member has a protective cover for protecting the mattress and/or the bed frame from damage from the fastening member. In one embodiment, the anchoring device is a continuous member, while in another embodiment the anchoring member is formed of at least two relatively movable members, with clamps, carried on the movable members, that releasably lock such members together to fit the size and shape of the mattress.

Abstract: A system for providing within the cockpit of an aircraft to the operator thereof a dynamic indication of climatic conditions at an airport. Such climatic conditions might include wind direction, wind speed, visibility, barometric pressure, temperature, and cloud height, among others. A transmitting station within the airport includes one or more climatic condition sensors such as a wind vane, an anemometer, a barometer, etc., an encoder for providing an encoded signal indicative of the sensed climatic conditions, and a radio transmitter for transmitting the encoded signal. A receiving station within the aircraft includes a radio receiver for receiving the transmitted encoded signal, a decoder for decoding the encoded signal to provide the dynamic climatic condition data, and a display for displaying that data.
