Such proposals should be as specific as possible, citing the paragraph number s , the proposed wording, and a detailed description of the reasons for the proposals, including any pertinent documentation. Upon request, the Committee will render an interpretation of any requirement of the Standard.
Interpretations can only be rendered in response to a written request sent to the Secretary of the Steel Stacks Standards Committee. The request for interpretation should be clear and unambiguous.
It is further recommended that the inquirer submit his request in the following format: Subject: Cite the applicable paragraph number s and concise description.
Edition: Cite the applicable edition of the Standard for which the interpretation is being requested. Question: Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation.
The inquirer may also include any plans or drawings, which are necessary to explain the question; however, they should not contain proprietary names or information. Requests that are not in this format will be rewritten in this format by the Committee prior to being answered, which may inadvertently change the intent of the original request.
ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. ASME does not approve, certify, rate, or endorse any item, construction, proprietary device, or activity.
Attending Committee Meetings. The Steel Stacks Standards Committee regularly holds meet- ings, which are open to the public.
Persons wishing to attend any meeting should contact the Secretary of the Steel Stacks Standards Committee. No reproduction may be made of this material without written consent of ASME. It applies to both single- and multiple-walled steel stacks, either of which can be lined or unlined. It also applies to steel stacks that are guyed or to certain aspects of tower stacks.
In this paper, the authors present a new STS control approach for powered lower limb prostheses, which is able to regulate the power delivery of the prosthetic knee joint to obtain natural STS motion similar to that displayed by healthy subjects. Mimicking the dynamic behavior of the knee in the STS, a unified control structure provides the desired control actions by combining an impedance function with a time-based ramp-up function.
The former provides the gradual energy release behavior desired in the rising phase, while the latter provides the gradual energy injection behavior desired in the loading phase. This simple and intuitive control structure automates the transition between the two phases, eliminating the need for explicit phase transition and facilitating the implementation in powered prostheses.
Human testing results demonstrated that this new control approach is able to generate a natural standing-up motion, which is well coordinated with the user's healthy-side motion in the STS process. Introduction Standing from a seated position is a common yet dynamically challenging task in people's daily life.
Due to the vertical ascent of the body's center of gravity, sit-to-stand STS transition requires high torque in the knee, far exceeding the joint torque in walking. Various biomechanical studies reported knee peak torques in STS as high as 2.
As a result, STS transition poses a major barrier to the mobility of individuals with lower limb motor impairments, including the transfemoral TF amputees i. A related study showed that TF amputees suffer from much higher asymmetry in ground reaction force and knee moments in the sit-to-stand motion, compared with no-amputee healthy individuals [ 3 ].
The inability of existing prostheses in generating enough knee torque and regulating the torque delivery in the STS seriously affects the mobility of the large population of TF amputees in their daily life. Motivated by this significant performance deficiency of traditional passive TF prostheses, researchers have expended substantial efforts in developing powered devices.
The pioneering work in this area was conducted by Flowers and Mann, which uses a hydraulic actuator to actuate the knee joint [ 4 ]. However, multiple drawbacks with hydraulics, such as leakage and lack of a compact supply, make it less attractive for prosthetic applications.
