There is disclosed a method for adjusting the temperature coefficient of resistance of a temperature-measuring resistive element comprising an electrically insulating base and a platinum film formed on the base. The new base station monitors signals from other base stations to determine how it relates to the other base stations. An egress port bitmap is determined based on a lookup in a forwarding table and it is determined if the destination address belongs to a trunk group of trunked ports. A remote RF electronics package drives the laser. Additionally, low-shrink andor better resiliency properties are also available with the addition of such nucleating compounds within the target high denier polypropylene resins. A hand controller is attached to the inflow and outflow tubes.
