Disclosed is a tamper resistant PIN entry apparatus for input of a key and for encryption of a password in a cash transaction machine. The PIN entry apparatus supplies the electric power to a memory of an electric circuit section, in such a manner that a first rod and a second rod of a rear case connect contacts of a key scan board, wherein the first rod is protruded on the rear of a key module including a button provided substantially on the front of the key module and the second rod of the rear case is coupled with the rear of the key module. At this time, in case that the rear case is removed from the key module or damaged, thereby changing the location of any one of the first and the second rods at the contact, the electric circuit section detects the event and destroys the memory itself physically. Otherwise, the electric circuit section makes information stored in the memory physically or softwarely unreadable, thereby preventing the leakage of the information.

Apparatus and methods for endoscopic colectomy are described herein. A colectomy device having a first and a second tissue approximation device is mounted on a colonoscope separated from one another. During deployment of the colectomy device, a diseased portion of the colon is positioned inbetween the tissue approximation devices. The tissue approximation devices are radially expanded such that they contact and grasp the colon wall at two sites adjacent to the diseased portion of the colon. The diseased portion is separated from the omentum and is transected using a laparoscope or is drawn into the colonoscope for later removal. The tissue approximation devices are then urged towards one another over the colonoscope to approximate the two free edges of the colon into contact together where they are fastened to one another using the tissue approximation device as a surgical stapler to create an end-to-end anastomosis.

One implementation of a method reassembles complete client-server conversation streams, applies decoders and / or decompressors, and analyzes the resulting data stream using multi-dimensional content profiling and / or weighted keyword-in-context. The method may detect the extrusion of the data, for example, even if the data has been modified from its original form and / or document type. The decoders may also uncover hidden transport mechanisms such as, for example, e-mail attachments. The method may further detect unauthorized (e.g., rogue) encrypted sessions and stop data transfers deemed malicious. The method allows, for example, for building 2 Gbps (Full-Duplex)-capable extrusion prevention machines.
