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.
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.
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.

Preferably, the current prize amounts corresponding to various potential winning game outcomes are displayed when a game is won, the displayed amount corresponding to the type of win paid. Preferably, a portion of wages is retained as a background amount to at least partially replenish a paid-out prize.
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.
Abstract: A gaming device and method for a hybrid game including a coordination/dexterity portion and/or traditional game portion is provided. Preferably, both a coordination/dexterity game and a traditional game are part of a single hybrid game, both of which portions are played using a single display device. In one embodiment, a player first plays a coordination/dexterity game and is given an opportunity to play a traditional game upon the occurrence of certain predetermined or predefined events during play of the coordination/dexterity game. Preferably, game outcome for both portions is controlled by an already-approved controller, such as a traditional game controller.

Abstract: A hanger is provided with two pairs of elongate arms supported by a base and two article gripping members attached to the arms. The hanger is suited for holding stick tools, such as gas or electric lawn trimmers and lawn edgers, in a vertical position.
Abstract: The invention relates to a sensor for the measurement of gas concentrations in a gas mixture, comprising a ceramic sensor tube that is closed at one end, arranged in a casing, and exhibits an outer surface which consists at least partially of a solid electrolyte material, and with at least one sensor contact and at least one heating contact with an active heating surface arranged along its exterior. To provide a gas sensor with a short response time that continues to operate precisely and with long-term stability in hot exhaust gases, sensor contacts are screen-printed onto the sensor tube, where at least the active heating surface is arranged in rotational symmetry around the perimeter of the sensor tube and where the heating contact is arranged on an electrically insulating layer applied to the solid electrolyte material in such a way that it does not cover the sensor contact, of which there is at least one.
