Electronic equipment according to the present invention can be attached removably to another device with screws 5a and 5b. The connector includes a plurality of cantilever contacts electrically connected to an IC card, each including a stationary arm and a resilient arm having a tip formed with a contact point. Each bore has a larger diameter opening on the top of the disc and a smaller diameter opening on the bottom of the disc. The third party recommendations may be a top-N list of recommended items for a given third party, and may optionally include a recommendation score and an indication of whether or not the third party actually selected the recommended item. The movement can be triggered, for example, by the dead weight in an open cooling cycle system or else by means of a piston in a closed cooling cycle system. In particular, the present invention provides a method employing GPS technology to define IP addresses in a mobile environment in order to reduce delays and transient data loss caused by handoff from one network to another.
