Abstract: In response to the occurrence of a restricted event in a computing device, a user of the computing device is presenting with a challenge including information designed to assist in determining whether the challenge is answered by a human. If it is determined that the challenge was not answered by a human, the restricted event is counteracted.

Abstract: A bi-directional communication system (12) is utilized for communications between a technician at an imaging workstation (18), from which imaging protocols can be conducted and at which diagnostic images can be displayed, and one or more hospital medical professionals, located at remote locations. The technician selects and addresses the proper medical professional by a use of an addressing means (50) at workstation (18). The technician selects images (42) to be sent to the selected medical professional. The images and medical professional's address are formatted (46) into wireless transmission format via transmitter/receiver (44) coupled to the workstation (18). A plurality of remote transmitters/receivers (62) receives wireless transmissions at remote locations. Each wireless transmission is examined (68) for a correct address and further converted (70) into an appropriate format for human-readable display.

Abstract: A cost is determined for events related to the modification of system configuration parameter values in a computing device. If the cost meets or exceeds a threshold, a challenge is presented to a user of the computing device. If the user does not answer the challenge correctly, the system configuration parameters are reverted to their original values.

Abstract: The invention relates to relatively short peptides (termed ?-conotoxins herein), about 10-25 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogous to the naturally available peptides, and which preferably include two disulfide bonds. The ?-conotoxins, as described herein, are useful for as neuromuscular blocking agents, such as muscle relaxants.
