Abstract: Methods, systems, and configured storage media are provided for discovering software updates, discovering if a given computer can use the software update, and then updating the computers with the software as needed automatically across a network without storing the updates on an intermediate machine within the network. Furthermore, when a failure is detected, the rollout is stopped and the software can be automatically removed from those computers that already were updated. The software update can be stored originally at an address that is inaccessible through the network firewall by intermediately uploading the software update to an update computer which is not a part of the network but has access through the firewall, which is then used to distribute the update.

Abstract: A protection circuit for intrinsically safe electromagnetic actuators operating on the voltage from a power unit (1) approved for underground mining, for switching electrohydraulic valves (5) in underground mining, comprising at least two spaced-apart short-circuit means (14, 16 or 16A) connected in parallel with the electromagnetic actuator coil (11) for short-circuiting the coil in the event of a reversal of the coil voltage. According to the invention, at least one of the short-circuit means comprises a short-circuit semi-conductor switch (16 or 16A) and a voltage-reversal detecting circuit (30) for activating the short-circuit semiconductor switch (16).

Abstract: Methods of playing a poker game are provided. One is a method for playing a single five-card hand and involves making an initial wager, dealing an initial three cards into the hand, making additional wagers to receive fourth and fifth cards, if desired, or folding, then deciding to keep or discard each card, whereupon all discarded cards are replaced and the value of the hand calculated and paid. A second method allows play of two hands, using two separate decks. The hands may be related to each other by allowing the player the option of duplicating the first three cards dealt into a first hand into a second hand. The game may be played with actual cards or with virtual cards using a programmed electronic game, preferably a casino-style game providing slots, magnetic card readers, or other means for inserting money, chips, or credit numbers to activate the game, and means for paying out winnings, as are known to the art.

Abstract: A method of simultaneously playing multiple hands of a poker game dealt from a single deck is provided. The player places an initial wager, and three to five cards are initially dealt from the deck into a first hand. The player may hold the cards in the first hand or move cards from the first hand into second, or third or subsequent hands. After the player moves each card from the first hand, a new card is dealt from the deck into the vacant position left in the first hand. When all the cards in the first hand have been held or moved into vacant positions in the second, third or subsequent hands, cards are dealt from the deck to fill in the remaining vacant positions in all the hands. The value of the poker hands is determined, and the player paid off in accordance with a predetermined payoff schedule. A casino-style electronic game implementing this method is also provided.
