Abstract: A pointer for mounting on an amusement park ride, the pointer having a grip adapted to be held by at least one hand of a user, a grip detection device integrated into the grip for detecting when the grip is held by the user, and a pivot unit pivotably coupling the grip to the amusement park ride, the pivot unit operable between an uninhibited state, in which the pivot unit permits the grip to freely pivot in at least a first direction and a second direction, and an inhibited state, in which the pivot unit inhibits the grip from pivoting in at least the second direction, wherein the pivot unit may transition to the uninhibited state when the grip detection device detects the grip is held by the user and the pivot unit may return to the inhibited state when the grip detection device detects the grip is released.

Abstract: A system, method, and computer program product for allowing a first processor to access flash or other non-volatile memory that is associated with a second processor. The first processor obtains parameters that allow the initialization of an internet protocol (IP) stack. The parameters can be obtained using the trivial file transfer protocol (TFTP), for example. The first processor communicates with the second processor using a socket protocol, sending a command word that represents either a read or write command. The command word specifies where in the non-volatile memory the access is to occur, and for how many bytes. Information is then returned to the first processor, allowing the first processor to verify the success of the access.

Abstract: Novel 1,2,3,4-tetrahydro-[9H-pyrido-[3,4-b]-indoles of the formula ##STR1## wherein R and R.sub.1 are individually selected from the group consisting of hydrogen, halogen, hydroxy, alkoxy of 1 to 5 carbon atoms and benzyloxy with the proviso that R.sub.1 is not hydroxy when R is halogen, alkoxy or benzyloxy and their non-toxic, pharmaceutically acceptable acid addition salts having tranquillizing properties and their preparation.
