摘要:
A die member is provided for a self-piercing riveting process, the die member comprising a die cavity having an axis and a plurality of sides positioned about the axis, wherein each side extends along a plane which includes a chord connecting two points along a circle centered on the axis.
摘要:
A method of joining parts together with a self-piercing rivet that is inserted through a part and partially through a second part. The second part includes a fiber-filled layer and a resin matrix layer that together form a composite part. A self-piercing rivet extends into the second part, but does not penetrate completely through the matrix layer. An assembly, including a first part and a second part that includes a reinforced layer and a resin layer in which a fastener is inserted, but does not extend through the second layer. A composite part including a first layer of resin matrix reinforces the filler and a second layer of resin matrix that does not include a filler and is more than 3 microns thick.

摘要:
A breastfeeding assist timepiece which includes a live time display combined with an iteratively resettable display, such further including a rotatable bezel feature which is repositionable between right and left sides of an associated crystal display and which, in combination with optional hour markings placed along the crystal display sides or upon the rotatable bezel, assists in establishing a dual-breast feeding cadence.
摘要:
A breastfeeding assist timepiece includes a housing containing a first live time display and a second resettable static time display. A left/right side indicator is defined at a further location of said housing. In use, the static time display is continuously reset to a time of a most recently completed feeding, with the left/right side indicator further designating a left or right breast employed first in the most recent feeding and in order to more accurately predict the timing of a present or future feeding, as well as which breast to be initially employed in that feeding.
