An aid for dining in stand-up and similar situations where a person may simultaneously support a plate and a beverage container by a single hand. In an embodiment, these filters are generated in order to block inputs which would otherwise disrupt the normal functioning of a program. The housing further defines, within the connector receptacle region, a plurality of spaced-apart leaf spring connective contacts. The measures are updated based on both positive examples, such as documents the user bookmarks, and negative examples, such as search results that the user does not follow. In alternative embodiments, the method further includes the step of storing the modified document, storing the identity of the user who modified the document, notifying one or more members of a group if the document is modified or transmitting the modified document to one or more members of a group. In one embodiment of a temperature sensor, first and second oscillators of different temperature characteristics are coupled to a differential frequency discriminator circuit.
