Abstract: A well water system includes a two piece modular adaptor that allows the pressure controls to be readily detached from the plumbing of the well water system. The modular adaptor includes a hollow adaptor body and a detachable adaptor coupler, which connects the pressure control and a pressure gauge to the modular adaptor. The detachable coupler allows the pressure controller to be completely disconnected from the well water system without reworking the existing plumbing and reduces the potential of major water leaks.

Abstract: A well water system includes a pressure switch adapted to monitor air pressure within a pressure tank, rather than water pressure within plumbing. The pressure switch is connected directly to the pressure tank by a tank adaptor in fluid communication with the pressurized air inside the tank. With the tank adaptor directly connecting the pressure tank to the pressure switch, the pump is actuated based on air pressure changes within the tank rather than water pressure changes in the plumbing. The pressure switch is calibrated to activate the pump when the air pressure within the pressure tank drops below a predetermined pressure, which correlates to a certain water pressure within the system. When the air pressure within the pressure tank is restored to a predetermined maximum, the pressure switch deactivates the pump having filled the tank to the desired maximum water threshold.

Abstract: A method of indicating extant battery life has the steps of initially determining a first extant battery life value having a first confidence level and generating a perceivable indication of the first battery life value. The method also has the step of determining a second extant battery life value having a second confidence level and generating a perceivable indication of the second battery life value after generating the perceivable indication of the first battery life value. The second confidence level is higher than the first confidence level and the determination of the first extant battery life value is completed before the determination of the second extant battery life value is completed.

Abstract: Accurate determination of extant battery life in a battery powered apparatus is a relatively slow process resulting in an undesirable delay in producing an indication of extant battery life. In order to solve this problem a quick but relatively inaccurate extant battery life determining technique is used to produce an indication of extant battery life until the more accurate value becomes available and can be used for producing an indication of extant battery life. The style of indication may be different for the two levels of confidence.

Abstract: A modular processor unit, known as an ASP unit (50), is provided for intelligently enhancing a conventional physical security system (20) without significant reconfiguration. The unit (50) is installable between conventional sensors (30) and a conventional transponder (28), the transponder being in communication with a central control station (22) of the system. The ASP unit (50) analyzes, over a period of time, a plurality of preselected features of the signal received from said sensor and used the features to evaluate a polynomial and thereby classify an event as an intrusion or a nuisance. The ASP unit (50) further includes an output state simulation relay switch (72) responsive to the classification for simulating an element of the sensor (30) and for providing an output state to the transponder (28). In one embodiment, the ASP unit (50) is connected by an ASP communications network (52) to a retraining workstation (54).
