  • Sparkplug health determination in engine ignition system
    Patent number: 10544773
    Abstract: An engine ignition system for a spark-ignited engine includes a sparkplug and a control system having primary ignition circuitry, secondary ignition circuitry coupled with electrodes of the sparkplug, and sensing circuitry. A control device determines a timing of spark production based on a pattern of varying of an electrical property in the primary ignition circuitry. An inflection point in a sensed current signal may be detected to determine the timing.

  • System and method for managing a plurality of rental facilities
    Publication number: 20030023453
    Abstract: Rental information is stored in a central database. A request to conduct a rental facility transaction is received from a user of web browser over a network. The requested rental transaction is conducted at a central processing center using the rental information. A result for the rental facility transaction is communicated back to the web browser of the user. The rental facility transaction may include operational transactions and management transactions. Changes made by one rental facility transaction are available to subsequent rental facility transactions in real-time.
