  • Patent number: 10423913
    Abstract: A method for process-based analysis may include the steps of: (1) defining a process, the process including a set of steps, (2) identifying risks and/or issues associated the process and/or peripheral symbiotic essentials, a risk and/or issue being associated with a step of the set of steps, (3) assessing the risk and/or the issue based on at least one attribute of the risk and/or the issue, and (4) prioritizing the risks and/or the issues for disposition.
    Type: Grant

  • Patent number: 4817137
    Abstract: An apparatus for effectively monitoring the hook status of a remotely stationed telephone, and a sub-audible tone associated with a corresponding alarm reporting device, monitors variations in impedance in the subscriber loop, preferably from the central facility which is monitoring the remote location. To this end, a disturbance (voltaage signal) is introduced onto the subscriber loop by an appropriate source. Steps are then taken to measure potential variations in this voltage signal, and to determine the hook status of the subscriber loop based upon these variations in potential. To make sure that the ancillary equipment which is being connected to the telephone network will not adversely affect basic telephone services, care is taken to make sure that the signal which is introduced onto the subscriber loop will neither create audible noises on the telephone line, nor interfere with the operation of the switching equipment of the telephone company.

  • Patent number: 4644103
    Abstract: In activating a unit for monitoring a remote instrumentality, a tone-responsive circuit operates in accordance with an established duty cycle wherein, for a major portion of each cycle, current is drawn from the telephone lines servicing the system at a rate which is within the range permitted by prevailing telephone regulations, to charge a capacitor over time, and wherein, for a minor portion of each cycle, the charge stored by the capacitor is used to briefly operate a tone detection circuit which is capable of determining whether or not the remote instrumentality is being interrogated. If no such tones are detected, the circuit continues its periodic operation as previously described. If tones indicating a desired interrogation are detected, the tone-responsive circuit activates the monitoring unit which is used to poll the instrumentality.
