Abstract: A tubular device including a tubular having a continuous wall and a substantially constant inner radial dimension and an outer surface that varies in radial dimensions configured to lessen a reduction in a longitudinal dimension of the tubular in response to radial expansion of the tubular in comparison to a reduction in the longitudinal dimension of a constantly-dimensioned-inner-and-outer-radially-surfaced-tubular made of a same material as the tubular.

Abstract: A torque transfer arrangement includes a relatively immobile construct; a relatively mobile construct. The relatively mobile construct is radially adjacent the relatively immobile construct. One or more torque body assemblies are mounted to the relatively mobile construct. The assemblies are radially responsive to applied hydraulic pressure to contact a surface of a separate structure and transmit torque from the arrangement to the separate structure. A method is included.

Abstract: A method, apparatus, and system are directed towards managing unsolicited email messages, and the like, in part, by providing segmentation of an email inbox. In one embodiment, the email inbox is segmented into segments associated with a message from a trusted, trusted email address, an untrusted email address, and a segment for a bulk email message, such as spam, and the like. A determination that the message is from a trusted email address may be made based, in part, on whether the email address is associated with one's address book, a degree of separation that may be determined based on an association with another's address book, whether the email address was a sent email address, and the like. By segmenting the email inbox, the invention minimizes a risk associated with incorrectly discarding a message from a desired, but untrusted source.
