Transmitter antenna

An apparatus for monitoring an article or system, particularly an LP or propane tank, includes a transmission unit, a base unit and a host unit. The transmission unit is disposed on or near the article or system and detects at least one parameter related to the article or system and send information related to the detected parameter. The base unit is disposed at a predetermined location remote from the article or system. The base unit receives information related to the detected parameter from the transmission unit. The host unit is disposed at a location remote from the base unit and the transmission unit. The host unit receives information related to the detected parameter from the base unit for management purposes. A method of monitoring an article or system such as a fuel tank is also disclosed.

Monitoring technology

Controller and display

A data protector for telephony test equipment, comprising a relay for selectively connecting the telephony test equipment to a telecommunication line, and electronic circuitry. The electronic circuitry includes a detector portion adapted for detecting signals within a continuous band of frequencies present on the telecommunication line, and a microcontroller. The microcontroller has a frequency counter function for determining whether data is present on the telecommunication line, a relay connect control function for selectively controlling the relay to connect the telephony test equipment to the telecommunication line, and an alert operator function for producing a signal if the detected frequency is above a predetermined threshold. A method for preventing telephony test equipment from unintentionally disrupting signals on telecommunication lines, comprising the steps of: providing a relay between the telecommunication test equipment and the telecommunication line; providing electronic circuitry including a single band frequency counter; determining whether data signals are present on the telecommunication line using the single band frequency counter; in response to determining that data signals are not present on the line, closing the relay to connect the telecommunication test equipment to the telecommunication line; and in response to determining that data signals are present on the line, providing an indication to the technician that data is present and preventing connection between the telecommunication test equipment and the telecommunication line.

In-line telephony data protector with line condition announce

A method for communicating data from one or more remote computerized coin telephone auditing devices to a central computer via a telephone line, which comprises the steps of receiving input data signals at a remote computerized auditing device, decoding the input data signals into digital data, and processing and storing the data signals. The digital data are then retrieved. The processing, storing and retrieving steps are accomplished by reading and writing the digital data from volatile memory to a non-volatile memory, and from non-volatile memory to volatile memory. The digital data is coded into corresponding output data signals, and are transmitted to the central computer via the telephone line. The receiving and transmitting steps are accomplished by the exchange of a predetermined sequence of data signals, whereby the remote computerized device and the central computer correctly identify each data signal. Finally, the method periodically disrupts the method for a predetermined time period, whereby power consumption by the remote computerized device is temporarily disrupted.

Method of communicating data from remote devices to a central computer

Apparatus for auditing the usage and indicating the status of a remote coin telephone system to a central computer via a telephone line. The apparatus comprises a power conversion and supply section connected to the telephone line and which derives current from it. The power conversion and supply section has a capacitor for periodically storing and providing electric charge. A microcontroller is connected to the power conversion and supply section. The apparatus also comprises a data signal reception and transmission section, which is connected to the microcontroller and to the telephone line, and a circuit section which detects telephone line voltage, current and frequency signals connected to the telephone line, which are a function of the operation of the audited coin telephone system. Finally the apparatus has a program logic residing in the microcontroller, which receives data signals and waveforms pertaining to the operation of the audited coin telephone system and reports them to the central computer at predetermined time intervals. The program logic also periodically disrupts power usage by the apparatus.

Monitoring system for remote devices

Telecommunications test connector

A dual unit diagnostic system for testing the physical status of a multi-pair cable. Each unit comprises connectors which are connectable to the cable wire pairs, and switches that are connected to the connectors, and are also activatable to provide distinguishable conductive pathways between each wire pair. A signal transmission section is connected to the switches, and provides a signal to a selected wires. A signal reception section is also connected to the switches for receiving a signal from distinguishable wires. A microprocessor is connected to the transmission section and the detection section, and which controls the transmission and reception of signals. A display is connected to the microprocessor and switches, and provides information to distinguish various physical wire status conditions based on the reception of the signal at predetermined wires.

Telecommunications cable tester

A telephone line test apparatus is provided for determining the operational status of a telephone line. The apparatus has a cylindrical and compact housing structure, a light emitting diode, a resistor, an electrical interface, and an elongated cable with a terminal modular connector. The electrical interface is disposed within the housing structure and connects the light emitting diode and the resistor in series. The modular connector is communicatively connected to the electrical interface and flexible extends from the housing structure for easy and reliable use. The light emitting diode is a tri-state LED which indicates the presence of D.C. voltage and polarity, as well as A.C. voltage.

Compact telephone line test apparatus

A ladder securing device for securing a ladder to a utility pole or the like. The ladder securing device has a main elongated and flexible strap member having looped ends, with one end forming a hand loop for the user of the device. A quick release adjustment buckle is provided for adjustably engaging the main strap member. An elongated, flexible buckle strap is secured to the adjustment buckle at one end and which has a loop at its opposite end. A pair of hooks are provided for engaging the rail of the ladder. One hook is attached to the end of the main strap member opposite the hand loop and the other hook is attached to the buckle strap at the end opposite its attachment to the buckle. The device, when placed in an X-configuration about a utility pole and with the hooks attached to the rails of the ladder, permits the quick securement of the ladder to a utility pole by pulling on the hand loop. Ladder securing device constructions are provided, as well as method steps utilizing the devices to safely secure a ladder to utility poles or the like, for subsequent safe and stable use.
