  • Publication number: 20170004681
    Abstract: A gaming system comprises a display controlled by the gaming system to display a prior jackpot value of a jackpot corresponding to a value of the jackpot when a previous jackpot trigger event occurred. The gaming system is arranged to receive wagers on one or more games playable in the gaming system, increment a current value of the jackpot pool in memory of the gaming system based on the wagers, determine a jackpot event value of the jackpot responsive to a jackpot event occurring, the jackpot event value being the current value of the jackpot upon the jackpot event occurring and the jackpot event being independent of incrementing the jackpot, upon the player winning the jackpot responsive to the jackpot event, make an award to the player of the jackpot event value, and upon the player not winning the jackpot responsive to the jackpot event, set the jackpot event value as a new prior jackpot value and control the display to display the new prior jackpot value until the next jackpot event.

  • Patent number: 8992854
    Abstract: Disclosed is an assay device comprising liquid transport means adapted to take up a liquid sample and conduct the liquid to an analyte detection region operable to provide a test signal indicative of the presence and/or amount of an analyte in the liquid sample; the assay device further comprising a sample presence signal generation means, which is not generated by means of an immunoreaction. This sample presence signal generation means can comprise a colored portion, which is overlaid by a material (e.g. nitrocellulose) that is opaque, when dry, and translucent or transparent, when wet, to allow the colored portion to become visible to the user. In another embodiment the signal generation means comprises a color changing material which under-goes a change in its visible properties upon wetting (e.g. pH indication). A third embodiment uses a mobilizable detectable which, when wetted by the sample, is carried along resulting in a streaked line parallel with the flow direction.
