Abstract: A fuel truck is used to deliver fuel to vehicles parked at one or more locations. While the fuel truck is servicing vehicles, a user of the fuel truck uses a mobile device to assist in the management of fuel delivery. Specifically, each vehicle being serviced has a tag that is a capable of being read by the mobile device. The tag communicates information that identifies the vehicle, and the mobile device communicates with a meter on the fuel truck to track how much fuel is delivered to the identified vehicle. The mobile device also controls the meter such that fuel is allowed to flow only when the mobile device is aware of which vehicle is receiving the fuel. Thus, over time, the mobile device is able to track accurately which vehicle is receiving fuel so that the amount of fuel delivered to each vehicle can be precisely determined.

Abstract: A system and method for wireless transactions provides a software development kit (SDK) that provides accessibility to inherent communication capabilities within a wireless communication device. The communication capabilities are normally not accessible to a software developer. However, the SDK provides an appropriate interface that permits a software developer to create application programs for a variety of transactions between the wireless communication device and a mobile network operator (MNO). In some transactions, the MNO may function as a financial service provider in which a user has an account with an associated monetary value. The SDK provides a simplified technique for executing a financial transaction, such as making a payment or transferring money by presenting easy-to-use menus that avoid the difficulty of memorizing transaction codes, user phone numbers, and the like.

Abstract: A system can implement a delivery service for a service region by monitoring, for each respective sub-region of the service region, supply conditions corresponding to transport providers available to deliver menu items from menu item suppliers to requesting users. When the supply conditions have dropped below the equilibrium threshold for a respective sub-region, the system can initiate a supply-constrained mode for the respective sub-region in which the system inputs each respective menu item request received, corresponding to a delivery location within the respective sub-region, into a queue, and dynamically determines a fulfillment probability for the respective menu item request. When the fulfillment probability of the respective menu item request exceeds a fulfillment threshold, the system can transmit the respective menu item request to a corresponding menu item supplier for preparation of a corresponding menu item and coordinate delivery of the corresponding menu item to the requesting user.
