Abstract: An RF tag with integrated anti-theft device allows a user, having a mobile device, to perform a secure purchasing application where the user uses the camera of the mobile device to read a barcode of a product and an RF tag with an integrated anti-theft device. The user can select the product he wishes to buy, check the information concerning that product, purchase the product, and disable the anti-theft device to go through a security portal without triggering the alarm.

Abstract: A system and method for defining class material based on students profiles including: adding learning objects by the user through input/output interface to a class builder module, in an iterative process; automatically or manually generating the group of students by the user; processing the learning object recommendations considering a recommendation system algorithm, machine learning, rules-based system or any algorithm of artificial intelligence; removing the recommendations if the user does not accept the recommendations; requesting the generation of more recommendations by the user, in an iterative process; creating a class package; and storing the class package in the class compositions repository in domain dependent databases.

Abstract: A heated fuel injector system and controller that includes a temperature sensing means to provide closed-loop control of a heating element heating fuel dispensed by a heated fuel injector. Closed-loop control provides more accurate temperature control of the heating element so that fuel heating is provided as quickly as possible while also protecting the fuel from being boiled and protecting the heated fuel injector from being damaged by excessive temperature. By monitoring how the signal from the temperature sensing means varies over time, fault conditions such as a lack of fuel flow, and fuel ethanol percentage may be detected.

Abstract: A heated fuel injector includes a heated body, liquid fuel flowing through a fuel passage within the body, and a member that increases heat transfer from the heated body to the fuel within the fuel passage. The thermal efficiency of the fuel injector is increased separately or in combination by diverting the fuel flow along an inner circumferential contour of the heated body, by limiting the volume of fuel bypassing the heated inner surface of the body, by redirecting heat from the body to unheated portions of the fuel flow field within the fuel passage, and by increasing the available contact surface area for heat transfer. Improved heat transfer from the heated body to the fuel is achieved by integrating features that increase the contact surface area into the inside surface of the body or by positioning an insulating or a thermally conductive spacer within the fuel passage.

Abstract: An engine management and fuel delivery system allows an internal combustion engine to operate on liquid fuel such as gasoline, ethanol or a blend thereof, or compressed natural gas (CNG). A first set of fuel injectors is configured to deliver liquid fuel to the cylinders. A second set of fuel injectors is configured to deliver natural gas to the cylinders. An electronic controller is configured to generate fuel injection signals for one of the sets of injectors. An injector selector is configured to direct such fuel injection signals to either the first set of fuel injectors or the second set of fuel injectors based on a fuel type command. The fuel type command is indicative of a desired fuel type selected from either liquid fuel or CNG fuel. The fuel type command is synchronized in accordance with an engine crankshaft position signal in order to coordinate the switchover, for each one of the fuel injection signals, one by one, as each fuel injection event is completed.
