Abstract: A method of providing reservation status relating to a group of objects includes providing a database for containing (i) availability data describing availability of at least one of the group of objects, and (ii) reservation data describing allocation of at least one of the group of objects. The availability data and the reservation data are stored in sparse form. The method further includes extracting, from the database, availability data and reservation data corresponding to a predetermined period of time, and combining the extracted availability data and reservation data to form windowed data in a dense format. The method also includes receiving the windowed data and providing the windowed data in a bit-vector view, and sampling the windowed data in the bit-vector view to produce sampled data. The sampled data provides the reservation status as a static view of the windowed data in the bit-vector view.

Abstract: Methods, systems, and devices for reserving a reservable asset using a mobile device. A mobile device communicates directly with a vehicle-associated control module or through a reservation server using either a TCP/IP communications channel or near-field communications. A member enters a request using the user interface provided by the mobile-device application. The identity of the member is validated the vehicle-associated control module executes the request by sending a signal to a computer or sensor in the vehicle through the vehicle wiring or the vehicle CANbus. The request can be a function, such as unlocking the vehicle doors, illuminating the interior or exterior lights, honking the horn, or activating a panic alarm.
