  • Patent number: 5547514
    Abstract: An apparatus mounted on a vehicle frame for cleaning liquids and solids from a sub-surface enclosure. The apparatus comprises a water tank having a drain valve and a feed valve. A water pump is connected to the feed valve that supplies water to a high pressure cleaning device used for loosening waste solids in the sub-surface enclosure. A suction pump connected to a suction hose removes the waste from the sub-surface enclosure and directs it to either of two waste tanks through a valve configuration comprising an inlet valve connected to one waste tank and a second inlet valve connected to the other waste tank. The two inlet valves selectively allow the waste removed from the sub-surface enclosure to enter either the first waste tank, the second waste tank or both. A method for cleaning the sub-surface enclosure is also provided.

  • Patent number: 4636947
    Abstract: A method and apparatus are provided for reducing customer transaction time in an automated teller machine (ATM) having various peripheral devices associated therewith. Each peripheral device associated with the ATM; e.g. a card handler mechanism, a printer mechanism, one or more cash dispenser mechanisms, and a depository mechanism, include a dedicated processor and memory for controlling the operation of the peripheral device connected thereto. The ATM also includes a peripheral control unit connected to the various subsystem controllers and to an ATM control unit for receiving generated transaction sequence event messages and in response thereto concurrently processing the messages to initiate simultaneous real-time operation of the various peripheral devices. For example, the concurrent processing of transaction sequence event messages allows completion of the card ready activity, entry of a customer PIN and printing of the customer receipt header to take place simultaneously.

  • Patent number: 4488254
    Abstract: A method and apparatus for displaying frames of information on a CRT screen which reduces the memory requirements of the system by representing the words used in the message frames and the horizontal and vertical relationships between the words as single symbols. The repertoire of words used to construct the messages is stored only once, along with the symbols, significantly reducing the memory requirements of the system.

  • Patent number: 4179031
    Abstract: A document dispensing system for dispensing documents or bills from a source to a customer access receptacle or a reject bin depending upon certain characteristics of the bills or the manner in which they are fed. Sensors which are positioned along a dispensing path are sampled to produce first and second states therein in accordance with the presence or absence, respectively, of bills in the dispensing path. The states of the sensors are stored to provide short term and long term histories of the sensors along with a time in transport for each of the bills in the dispensing path. The short and long term histories and the time in transport are utilized for evaluating the status of each of the bills in the dispensing path with regard to predetermined criteria such as, for example, "double thickness", or "bill too long", and for producing a control signal which controls a diverter gate to divert the bills into the access receptacle or reject bin in accordance with the evaluation.
