The present invention relates to nucleotide sequences of TCL-1 genes and amino acid sequences of their encoded proteins, as well as derivatives and analogs thereof, and antibodies thereto. An architecture for a host computer allows multi-tasking application programs to interface with the force feedback device without conflicts. Heat may be applied to the piezoelectric element. The first transfer pads are electrically connected with the second transfer pads, and the first and second transfer pads are used to transmit a touch control signal to the touch panel.
