  • Patent number: 6335861
    Abstract: An instrument comprises first and second modules. The modules each comprise computer electronics hardware including a display screen typically carried by the first module. The modules are separable from each other. One of the modules has a projecting bus for connection with the interior of the other module. The bus defines a plurality of sockets for removably receiving circuit boards of desired variable types for direct connection with electronics within the other module and for connection with electronics of the one module through the bus. Thus, the instrument is easily modified in its functioning by addition, subtraction, or replacement of circuit boards from the bus.

  • Patent number: 6318721
    Abstract: An operation device is attached externally, e.g., by magnetic tape to a coin-operated entertainment machine, the machine have an actuable player operable button such as a stop button or a gamble button. The device is operable to detect when the player operable button is actuable and, in response, to operate the button. The device may detect the actuability of the button by, for example, detecting the illumination of a lamp in the button or other part of the machine, or by detection of a change in voltage/current associated with the button's actuability. In a preferred embodiment, the button is a push button and the operation device is attached so as to bridge the button. The device incorporates a cam mechanism to operate, i.e., push, the button on detection of an appropriate signal indicating that the button is actuable. In another embodiment, the device incorporates a solenoid-operated member to operate the button.

  • Patent number: 6308479
    Abstract: A system for diverting rain water from the underside of a deck structure is comprised of a side-by-side array of flexible water-collecting elements , each of which collect and divert rain water from a regional area of the deck structure. Each water-collecting element is shaped to control the flow of water without restriction or impediment. This shape further increases the rigidity to the water-collecting element making it relatively easy to install and support. Coupling elements are interposed between adjacent water-collecting elements which function to fix them together such that the resulting array gains structural properties and impermeability comparable to a single corrugated sheet of the same material. Mounting elements secure this array to the underside of the deck. The result is an aesthetically attractive and environmentally rugged system which is realized with very economical components.

  • Patent number: 6270840
    Abstract: An apparatus and method technique for producing plane-parallel flakes is disclosed. In a preferred embodiment, the present invention is realized through a multi-chamber apparatus for producing plane-parallel flakes from layers vapor deposited in vacuum on an endlessly circulating substrate. The present invention includes the sequential steps of: vapor deposition of a separating agent layer in high vacuum on the endlessly circulating substrate; vapor deposition of one or more layers of metal, oxides, fluorides, and nitrides in high vacuum on the separating agent layer; and stripping the vapor deposited layers from the endlessly circulating substrate under low vacuum. The vapor deposited layers are subsequently present in a separate vacuum stage separated from the vapor deposition chamber by dynamic locks as a suspension of fine flakes in a mixture of solvent. and separating agent. The suspension may continuously or intermittently be transferred out of the separate vacuum stage for further processing.

  • Patent number: 6217541
    Abstract: A blood pump is provided which comprises a cross-flow pump head having an elongated generally cylindrical housing portion. The housing portion defines a blood inlet port on a surface thereof and a blood outlet port on an opposite surface thereof. An impeller within the housing portion provides cross-flow of the blood from the inlet port around and/or across the rotational axis of the impeller to the outlet, and a motor is provided for driving the cross-flow pump head. The blood pump may be small enough to permit percutaneous insertion of the pump into a patient's blood vessel, and thus may be utilizable as a left ventricular assist device. To this end, a collapsible polymeric outflow tube is coupled to the blood flow outlet and is adapted for directing the blood from the left ventricle to the aorta through the aortic valve.
