The present document discloses water-treatment, descaling, and monitoring systems that include components selected from among: (1) water-treatment components; (2) a component that protects system components, plumbing, and appliances from limescale build-up by generation of a pure sine-wave descaling signal that passes FCC requirements; (3) a component that generates an electrolysis-inhibiting signal; (4) components that monitor propagation and the strength of the descaling signal within the plumbing system; (5) probe and sensor components that monitor water quality, the operational status of other components, and system characteristics; (6) components that prevent the descaling signal from interfering with probes, sensors, and water-treatment-system components; (7) a component that generates UV radiation for eliminating biological contaminants within water heaters and other appliances; and (8) wireless-communications components that facilitate transmission of alerts regarding operational status and water quality, remote control of system components in response to alerts, receiving system firmware and parameter updates, and transmitting status and monitoring data.

Water-treatment, descaling, and monitoring system

The current document discloses a ground-detecting direct-wire descaler that detects and indicates whether or not a descaling signal with sufficient current and voltage is produced or, in other words, detects and indicates whether the pipe or other equipment to which the ground-detecting direct-wire descaler is coupled is isolated from AC ground. AC-ground detection occurs both on initial power on and at regular monitoring intervals. In certain implementations, ground-detecting direct-wire descaler additionally detects and indicates whether or not the three-pronged outlet, into which the power-cord plug of the ground-detecting direct-wire descaler is inserted, conforms to UBC standards and therefore has safety ground available for use as signal ground. The ground-detecting direct-wire descaler only attempts to produce a descaling signal when safety ground is detected.

An electronic hand-held device and method for inputting and sending requests and for receiving and outputting responses to the requests. The electronic hand-held device is a coupled to a telecommunications link over which requests are sent and responses are received. The electronic hand-held device can input request data in any number of different information media, including audio tones and voice signals, mechanical input to a keypad, printed bar codes, magnetic data stored in credit cards, and electronic data stored in electronic smart cards. The electronic hand-held device can output responses through an audio speaker, a visual LCD display device, and, optionally, through other output devices including printers. The electronic hand-held device is especially well suited for order entry and acquisition of product information.

Low-power hand-held transaction device

An electronic hand-held device and method for inputting and sending requests and for receiving and outputting responses to the requests. The electronic hand-held device is a coupled to a telecommunications link over which requests are sent and responses are received. The electronic hand-held device derives sufficient electrical power from the telecommunications link in order to power the internal components of the electronic hand-held device that input request data, format requests, send requests, receive responses, and output responses. The electronic hand-held device can input request data in any number of different information media, including audio tones and voice signals, mechanical input to a keypad, printed barcodes, magnetic data stored in credit cards, and electronic data stored in electronic smart cards. The electronic hand-held device can output responses through an audio speaker, a visual LCD display device, and, optionally, through other output devices including printers. The electronic hand-held device is especially well suited for order entry and acquisition of product information.

A dual time base, zero dead zone time domain reflectometer repetitively launches a predetermined number of stimulus pulses into a transmission system in synchronism with clock signals from a first time base, providing a measurement cycle. The duration of the launched stimulus pulses, determined by a predetermined number clock cycles from the first time base, exceeds the total propagation time of the system to be measured so that a time interval between a launch and a reflection may be measured within the launched pulse. A second time base, which has a predetermined period that differs from the period of the first time base and defines a measurement period divided into equal sub-periods, continuously produces clock signals, one or more of which may be counted during the time interval. The result is that over a predetermined number of repetitive pulses launched and associated time intervals presented to the second time base and count logic circuits, a count signal will be produced for each incremental sub-period occurring during the time interval being measured. Accordingly, the total count is proportional to the duration of the time interval being measured. Since the measured time interval is produced by the launched pulse and its reflection, there is no dead zone. Also, the circuit design is very simple, and lends itself to manifestation in a low cost, low power, hand-held and battery operated TDR for locating faults on 10 base-T, Token Ring, T1, Telco lines, and other twisted-wire pair applications in local area networks, as well as general cable testing.
