Abstract: A settlement card system includes a settlement card that is locked for authorized use with a single card specific merchant. A first computing system is operated by the card issuer and determines a transaction monetary limit and customer payment terms that differ for each subsequent, single transaction by the customer with the card specific merchant. A second computing system forwards the authorization request to the first computing system, which determines if the transaction is within the monetary limit determined for the customer, and if no, reject the transaction, if yes, accept the transaction and determine customer payment terms for that transaction. A third computing system makes payment to the authorized merchant for the transaction after receiving a payment authorization from the first computing system. The first computing system transfers a payment to the third computing system in the amount of the transaction.

Abstract: A wheelchair monitoring system including a sensor adapted to actuate upon a single rotation of a wheel of a conventional wheelchair. A sensor couple is included for securing the sensor adjacent to the wheel of the wheelchair. A display is coupled to the wheel chair for depicting a plurality of numerals. Finally, an information mechanism is connected to the sensor and display. The information mechanism is adapted to calculate a distance the wheelchair travelled and a speed of the wheelchair by monitoring the number and rate of actuation of the sensor, respectively. The information mechanism is further adapted to depict on the display the distance upon a first depression of a switch button and depict the speed upon a second depression thereof.
