Abstract: A garage door opener comprises at least two radio frequency transmitters, a radio frequency receiver, at least two memories, and a processor. Each memory corresponds to one radio frequency transmitter and stores a code of a corresponding radio frequency transmitter. The radio frequency transmitter is connected to the processor by electrical connectors. It is impossible to mis-study to the other radio frequency transmitter because the processor in the host computer has no program mode. Since each memory corresponds to one radio frequency transmitter, when one radio frequency transmitter is lost, a corresponding memory is eliminated to make the lost radio frequency transmitter disuse.

Abstract: Jelly pens are disclosed that may use a unitary elongate pen body made from an elastomer gel, the pen body having a longitudinal bore for insertion of an ink reservoir and writing tip therein. The use of elastomer gel for the entire pen body may provide a more desirable gripping surface on the pen and can provide a pen with a soft, floppy feel during use.
