    Abstract: A method, simulation, and apparatus are provided that are highly suitable for treatment of benign prostatic hyperplasia (BPH). A catheter is disclosed that includes a small diameter disk loaded monopole antenna surrounded by fusion material having a high heat of fusion and a melting point preferably at or near body temperature. Microwaves from the antenna heat prostatic tissue to promote necrosing of the prostatic tissue that relieves the pressure of the prostatic tissue against the urethra as the body reabsorbs the necrosed or dead tissue. The fusion material keeps the urethra cool by means of the heat of fusion of the fusion material. This prevents damage to the urethra while the prostatic tissue is necrosed. A computer simulation is provided that can be used to predict the resulting temperature profile produced in the prostatic tissue. By changing the various control features of the catheter and method of applying microwave energy a temperature profile can be predicted and produced that is similar to the temperature profile desired for the particular patient.

    Abstract: A power transfer system for applying backup electrical power to electrical systems is described which applies backup power automatically without power interruption and which is straightforward to implement and inexpensive to manufacture. The power transfer system has a direct current (DC) power bus as a common supply point for protected electrical equipment, thereby making prior art systems which provide power transfer between alternating current (AC) power sources and typically provide an AC power bus in common with the protected equipment no longer necessary.

    Abstract: A system and method for transmitting information in which a relatively narrowband signal is transmitted followed by the transmission of a relatively wideband signal. The narrowband signal may be used by the receiver to alert the receiver to the upcoming wideband signal. In a system in which the transmissions occur asynchronously to the receiver, the receiver may be less complicated because the receiver is provided with an indication of the time and/or the center frequency of the wideband signal. Either the narrowband signal or the wideband signal may be used to transmit information from the transmitting device to the receiver. The system and method find particular advantage in tracking and locating systems in which a plurality of tags asynchronously transmit information and/or location information to a receiver or a set of receivers.

    Abstract: Precipitating copper metal from copper bearing solutions using scrap iron as a precipitant to form free copper metal precipitate. The scrap iron is retained in an unflooded bed in a container having a rotatable nozzle for spraying the copper bearing solution in a high velocity jet stream which penetrates into the bed to react with the iron to form copper and strips off the copper metal from the scrap iron. In the bottom of the container is a sieve for retaining the scrap iron while withdrawing the copper metal and the expended solution.

    Abstract: A safe for storing ammunition or other heat-sensitive explosive materials. The safe includes a plurality of walls, a door attached to one of the plurality of walls, an interior space defined by the plurality of walls and the door, an opening extending through one of the plurality of walls or the door, a pane coupled over the opening, and a cover coupled to the one of the plurality of walls or the door adjacent the pane. The pane automatically exposes the opening when the interior space reaches a predetermined temperature, which is lower than the temperature at which ammunition or other heat-sensitive explosive material detonates. Accordingly, the safe provides for pressure release before the ammunition or other heat-sensitive explosive material detonates.

    Abstract: An invention for measuring, maintaining and correcting synchronization between signals which suffer varying relative delays during transmission and/or storage is shown. The present invention teaches measuring the relative delay between a plurality of signals which have suffered differing delays due to transmission, storage or other processing. The preferred embodiment of the invention includes the use of a marker which is generated in response to a second signal and combined with a first signal in a manner which ensures that the marker will not be lost in the expected processing of the first signal. Subsequently a first delayed marker is generated in response to the marker associated with or recovered from the first signal, and a second delayed marker is generated from the second signal. The first delayed marker and second delayed marker are compared to determine a measure of the relative timing or delay between said first signal and said second signal at said subsequent time.
