    Abstract: A water purification device including a water inlet that receives water generated by a condenser. The water purification device has a water heating apparatus that receives water from the water inlet. The water heating device has a thermal energy source that can pasteurize or flash pasteurize the water by heating the water to a predetermined temperature for a predetermined length of time. The water heating device expels the water at the end of the predetermined length of time.

    Abstract: A method and apparatus for measuring a change in the insertion loss of a transmission line in a communication system is disclosed. The method provides feeder cable insertion loss detection in a transmission system without interfering with normal operation. The method includes injecting a non-interfering signal at a predetermined frequency onto a cable providing normal operating signals to a narrowband device at a predetermined frequency, measuring the amplitude of the injected signal, measuring the amplitude of a reflected signal, the injected signal being reflected by the narrowband device and processing the amplitude of the injected signal and the amplitude of the reflected signal to derive a current insertion loss for the cable. In addition, the method further includes comparing the current insertion loss to a prior insertion loss and determining the cable to be defective when the current insertion loss differs from the prior insertion loss by a predetermined amount and replacing the cable when the current insertion loss differs from the prior insertion loss by the predetermined amount. The injecting further includes selecting a signal for injection having a frequency and power that does not interfere with the normal operating signals and which causes the signal to reflect back from the narrowband device. The frequency of the selected signal for injection causes the narrowband device to appear to the selected signal for injection as a short or an open. The narrowband device is an antenna, a low noise amplifier, a power amplifier, a filter or a RF-to-light converter for a fiber optic distribution network.

    Abstract: A trailered brake workstation mounts on the horizontal frame of a two-wheeled trailer, a pair of longitudinally-spaced transverse horizontal guide bars at an elevated position above the frame. The guide bars mount slides which are secured to the bottom of a longitudinally-disposed brake. Thus the brake, via the slides, can be shifted laterally on the horizontal guide bars between an internal or centered position it which it may be locked for hauling and storing, and a side position in which it may be locked and available for operative use. A box and a cover protect the brake in the internal or centered position from the elements. A work table may also be transported, being stored in the throat of the brake during transportation, and disposed for use on the other side of the trailer when the brake is operative.

    Abstract: A method and apparatus for maintaining component temperature in a base station is disclosed. The method and apparatus reduces or eliminates the time required for raising the internal temperature of components in a base station transceiver without incurring substantial cost. A power amplifier receives a signal at an input and provides an amplified signal at an output and a switch for switching between a first and a second bias circuit in response to a control signal, wherein the first bias circuit comprises an RF bias circuit for providing normal RF bias to the power amplifier and the second bias circuit is a cold start bias circuit for providing a cold start bias to the power amplifier. The power amplifier includes a power transistor. The cold start bias circuit causes the power transmitter to substantially increase an amount of heat dissipated by the power amplifier causing the temperature of the BTS to rise above de-ratings for the components. The temperature monitor also compares a measured temperature to a minimum and a maximum reference temperature. The temperature monitor provides a signal for engaging the switch causing the cold start bias circuit to be selected by the switch when the measured temperature is less than the minimum reference temperature and a signal for disengaging the switch causing the RF bias circuit to be selected by the switch when the measured temperature is greater than the minimum reference temperature.
