Abstract: A tread is configured to have three rows of tread elements, a center row and a pair of shoulder rows, the center row forming a circumferential rib positioned at an equatorial centerplane of the tread. Each shoulder row has a repeating circumferential array of upwardly extending elongate groove fingers, adjacent groove fingers within the repeating array of each shoulder row of groove fingers being connected by at least one laterally extending channel. An array of serrations line each longitudinal side of the channels, each serration defined by inward tapering serration sidewalls extending to a serration base surface. Each channel is submerged below an outward tread surface such that the submerged channel will emerge as the tread wears down.

Abstract: A customizable, portable identification and memory device includes a housing having a front sleeve housing member with a sleeve that receives a slideable printable card member and an electronic memory device, such as a universal serial bus (USB) flash drive, pivoted to the housing that is rotatable between a stored position of the memory device within a recess of the housing and one or more deployed positions of the memory device, for example, at 90 degrees and 180 degrees, in which a connector portion of the memory device is exposed for connection to a port of a computing device. The slideable printable card member can be imprinted with text and/or graphics, such as personal identification information and/or insurance information for a user and/or can be imprinted with allergies, medications, and emergency contact information for the user, and the memory device can store voluminous information, such as a personal health record (PHR) for a user.
