  • Publication number: 20210078404
    Abstract: A vehicle kill switch assembly includes a switch that is coupled to a vehicle. The switch is positioned beneath a driver's seat of the vehicle and the switch is electrically coupled to the ignition system of the vehicle. The ignition system is turned off when the switch is disengaged. A biasing unit is coupled to the vehicle and the driver's seat is coupled to the biasing unit. The biasing unit biases the driver's seat upwardly in the vehicle and the biasing unit is compressed when the driver sits in the driver's seat. The switch is engaged when the biasing unit is compressed to facilitate the vehicle to be driven. Conversely, the switch is disengaged when the biasing unit biases the driver's seat upwardly to inhibit the vehicle from being driven.

  • Publication number: 20190220850
    Abstract: Systems and methods are provided for pairing an electronic wallet for a consumer with a service provider. One exemplary method includes receiving, by a computing device, a request to pair the electronic wallet with the service provider where the electronic wallet is associated with an account and where the account is associated with a user, and requesting, by the computing device, consent from the user to pair the electronic wallet with the service provider. The method also includes generating, by the computing device, a pairing token for the wallet application and the service provider upon consent from the user, and storing the pairing token in association with the wallet application, whereby the service provider is permitted to use the pairing token in a subsequent network transaction involving an entity associated with the service provider and the wallet application, regardless of whether the wallet application is separately paired with the entity.

  • Patent number: 9296837
    Abstract: Methods and systems for pelletizing low molecular weight semi-crystalline polymers are provided herein. Polymer compositions comprising the semi-crystalline polymer and a solvent are provided to a devolatilizing device, where the solvent is at least partially evaporated under vacuum conditions, resulting in removal of heat from the polymer by evaporative cooling and crystallization of the polymer. Once the polymer has reached the desired temperature, the polymer exits the devolatilizer and is pelletized. Semi-crystalline polymers that may be used in the present invention include propylene-based copolymers, such as propylene-ethylene and propylene-hexene copolymers having a heat of fusion, Hf, from about 5 to about 75 J/g and a weight average molecular weight, Mw, from about 10,000 to about 200,000 g/mol.
