RFID tags were believed to be immune to power analysis since they have no direct connection to an external power supply. However, recent research has shown that they s are vulnerable to such attacks, since it is possible to measure their power consumption remotely via a completely passive attack. The method and apparatus of the invention protects RFID tags against simple and differential power attacks. The invention is particularly useful regarding inventory control systems or secure documents such as epassports. The basic technique is to use two capacitors embedded in the RFID tag in lo such a way that at any given time one of them is storing energy that is being generated by the charge pump of the tag that sucks energy from the electromagnetic or magnetic field of a tag reader, and the other one is discharging and powering the computational element of the tag chip.

An ink manifold defining multiple fluid flow paths has openings arranged for detachable connection with conduits in an interface. Shut off valves at each of the openings respectively, are biased open. An actuator biased to a closed position by a resilient element, where it holds all the shut off valves closed. The actuator engages the interface such that moving the interface into connection with the openings simultaneously moves the actuator to an open position where the shut off valves are able to open. The resilient element generates a bias greater than a combined bias exerted by the shut off valves on the actuator.

Electrically conductive polymer bumps are formed in electrical connection with circuitry supported by a first substrate. The polymer bumps are bonded with a conductive adhesive to circuitry supported by a second substrate, with the conductive adhesive being in electrical connection with the circuitry supported by the second substrate. Prior to said bonding, an effective amount of ultraviolet radiation is impinged onto the polymer bumps to enhance adhesion of the bumps with the conductive adhesive and electrical conduction between the circuitry of the first substrate and the circuitry of the second substrate. In one implementation, ultraviolet radiation of at least 340 nm is impinged onto conductive polymer bumps prior to subsequent bonding. In one implementation, ultraviolet radiation is impinged onto conductive polymer bumps for a time period less than one minute prior to subsequent bonding. In one implementation, ultraviolet radiation is impinged onto conductive polymer bumps to provide a total ultraviolet radiation exposure of greater than about 50 mJ/cm2 prior to subsequent bonding. In one implementation, ultraviolet radiation is impinged onto conductive polymer bumps in the absence of ozone other than any produced by said ultraviolet radiation prior to subsequent bonding. In one implementation, ultraviolet radiation is impinged onto conductive polymer bumps in an atmosphere consisting essentially of ambient room air prior to subsequent bonding.
