摘要:
A method for forming images useful as lithographic printing plate precursors is disclosed. An imageable element in which the imageable layer comprises an acid generator, a crosslinking agent, and a binder is imaged with ultraviolet radiation and developed with a solvent based developer. The acid generator is an iodonium, sulfonium, or diazonium salt in which the anion is an organic sulfate or thiosulfate anion. The binder comprises a copolymer that contains a reactive pendent group capable of undergoing acid crosslinking, in which the reactive pendent group is hydroxyl, carboxylic acid, sulfonamide, alkoxymethyl, or a mixture thereof. The method is especially suited for use with direct digital ultraviolet imaging devices. The resulting image is useful as a lithographic printing plate.

摘要:
A skill based game employing kickers to direct coins falling over the edge of a catcher plate to a player's hopper. The players deposit coins in a slot which directs the coins to a first catcher plate. Coins are pushed over the edge of this catcher plate to a second catcher plate where they are further pushed toward the edge of the second catcher plate. As coins accumulate, coins may fall over the edge of the second catcher plate. Kickers are disposed below the second catcher plate under a player's control. If a player employs the kicker correctly, the coins falling over the edge of the second catcher plate are directed to a player's hopper. If the player fails to employ the kickers correctly, coins fall into a hopper and are retained by the operator of the machine.
摘要:
A method for installing software to software-defined radio equipment. The method includes the step of transferring software to one or more software-defined radio devices from a remotely located software server. The software server can be a computer operatively connected to the software-defined radio device via a communications network. The transferring step can occur while the software-defined radio device continues to perform software-defined radio functions. The software can be stored to a portion of a data store associated with the software-defined radio device which is not being used as a storage for currently running software. The software can be loaded on a restart of the software defined device. An error indication can be provided if a fault occurs in the transferring step or the loading step. The method also can include the step of reverting from the selected software to a previous software version upon a fault occurrence.
