  • Publication number: 20230406323
    Abstract: A method of monitoring for circumvention of an ignition interlock system is described herein including detecting an electrical parameter associated with an electrical power state of a vehicle electrical system in a vehicle comprising an ignition interlock device that includes at least a relay device and a controller device electrically interconnected within the vehicle electrical system, measuring a rate of degradation associated with the electrical parameter of the vehicle electrical system, and comparing the electrical parameter to a threshold condition. The method further includes comparing the rate of degradation of the electrical parameter to a threshold rate. Depending on the rate of degradation, a violation state may be generated, a violation state may be reversed, a violation state may be maintained, a log entry may be generated, or more than one of these may occur.

  • Patent number: 11827230
    Abstract: A system and method of detecting an anti-circumvention attempt associated with an ignition interlock device of a vehicle. The method comprises detecting an electrical parameter associated with an electrical power state of the vehicle electrical system that includes the ignition interlock device having at least a relay device and a controller device electrically interconnected within the vehicle electrical system; comparing, responsive to the detecting, the electrical parameter to a threshold condition; inferring an IID circumvention event in accordance with the electrical parameter being one of above and below the threshold condition, and reporting, responsive to the inferring, the IID circumvention event to a central monitoring server computing system.

  • Patent number: 7047438
    Abstract: An apparatus, program product and method of mapping defects on a data storage medium analyze one or more previously-identified defects on a storage medium to detect any growth in those defects over time, such that any detected growth of a previously-identified defect can be accommodated for through the dynamic remapping of additional surface area adjacent the defect to one or more replacement regions located elsewhere on the storage medium. As such, any buffer regions defined around pre-existing defects are effectively maintained as those defects grow over time, thus maintaining suitable protection from data loss that would otherwise result from an attempt to store information in a region that has been impinged upon as a result of the growth of an adjacent defect.
