20130263689, Oct 10, 2013

Filed:

May 18, 2012

Appl. No.:

13/475557

Inventors:

Jeffrey B. Robinson - Gladwyne PA, US

International Classification:

G05G 1/12

US Classification:

74548

Abstract:

The invention relates to a bike stem and more generally to a stem for connecting a steering bar to a steering tube. The stem body is substantially hollow allowing the use of a locking member to engages the handlebar on one end and the steerer tube on the other end and can be secured by tightening bolts on only one end of the bike stem, thereby exerting pressure on the handlebars and to the locking member, which thereby applies a force to the steerer tube, securing the steerer tube to the bike stem without the need for bolts on the steerer tube side of the bike stem.

Abstract:

The steady state condition of a subject product is projected using transient data developed through actual or simulated tests or operations. The transient data represent the monotonic or cyclic property states of the product while subjected to environmental or operational conditions. A first and second property state value corresponding to the transient data for selected times within the test period are identified. A first and second rate-of-change value corresponding to the change in the property states at the selected times are then computed. A time constant value is next computed by applying the time interval and the first and the second rate-of-change values to a time constant function. A projected steady state condition value is next computed by applying the second rate-of-change value, the second state value and the time constant value to a projected steady state conditions function. The projected steady state condition value is compared with a previously computed projected steady state condition value.
