  • Patent number: 10163092
    Abstract: A network service operates to initialize and link a card instrument to a merchant or merchant location, so that the merchant can receive funds the service. One or more requests are detected to use the card instrument for one or more transactions, where each transaction involves a corresponding customer who has registered a customer funding account with the network service. For each of the transactions, a merchant account is funded using a funding account of the card instrument.

  • Publication number: 20180336549
    Abstract: A computer system can implement a network transaction service by receiving, over the one or more wireless networks, request data from mobile computing devices of requesting users of the network transaction service. The request data can identify the requesting user and include a transaction request to utilize the network transaction service at a merchant location of a registered merchant. In response to receiving the request data, the system can determine a merchant account of the registered merchant linked to the network transaction service, and identify a customer account of the requesting user. The computer system may then initiate fund transfers between a shared fund account of the network transaction service, the merchant account, and the customer account to fulfill the transaction request.

  • Patent number: 5896938
    Abstract: An electrohydraulic drilling system for drilling holes in material such as rock utilizing a drill stem connected to a flexible cable. The electrical spark or plasma that creates the electrohydraulic pressure wave is powered by an electrical pulse propagated down the cable from a pulse generator to the drill stem. An advance mechanism on a jackleg support is utilized to move the drill into the rock during the drilling process. The drill stem and cable combination enable holes to be drilled in the roof of tunnels where the floor to roof height is less than the depth of the hole to be drilled. The electrohydraulic process provides higher drilling efficiencies than conventional systems.

  • Patent number: 5560017
    Abstract: In a portable computer the BIOS software slows the system clock frequency during idle periods. The BIOS software returns the system to its normal operating frequency when an awaited event such as a keystroke occurs. In the event of an interrupt while the system clock is at the lower frequency, a hardware clock control circuit responds to the interrupt to promptly increase the system clock frequency to the normal value. By decoding the old frequency, new frequency and the several available frequencies, the change in frequency is timed to maintain proper phase and duty cycle without interruption.

  • Patent number: 5491495
    Abstract: A computer system hating a digitizing tablet overlaying the display screen. The tablet serves as a user's primary input device. Various features of the system make it possible for the user to run and interact with standard programs designed for keystroke and mouse input and not designed for use with a tablet. In addition to the main processor, on which the user's programs are executed, there is an interface processor. In addition to a standard display buffer, there is an ink plane buffer for interface display data that is combined with the data from the standard display buffer on a pixel-by-pixel basis according to data from a mask plane buffer. The interface processor manages input from the tablet, presents feedback to the user by means of the ink and mask planes, and provides keystroke and mouse data to the main processor as if from a standard keyboard controller. The interface processor presents the user with a collection of simulated devices, including standard devices such as a keyboard and a mouse.
