摘要:
A test vehicle for evaluating a manufacturing process for integrated circuits that uses a more space efficient layout of library driving cells arranged to produce circuits that exercise many interconnections that may be designed at the minimum design parameters of a manufacturing process. The cells can be configured to operate as ring oscillators increasing the effective circuit frequency of the test module allowing higher frequency circuit testing, and shortening the time it takes to perform life cycle testing. Visibly marking cells, combined with electrically isolating error prone circuit segments makes, identifying defects much more efficient. The accessibility of many testing methods allows quick location of root cause failures, which allows improvements to be made to the manufacturing process.

Bicycle saddles come in many different shapes and sizes. Some are long, some are short, some are curved some are flat. The ultimate goal is to find the perfect saddle for the cyclist.CLARIFICATION: those that ride bicycles are commonly referred to as cyclists, bikers, cyclists, bicycle cyclists, bicyclists, cycle cyclists, cycling, etc., but for this discussion, they will be referred to as ‘cyclist(s)’As with the height of humans, the widths of Ischial Tuberosities (Sit Bones) are also numerous. The Ischial Tuberosities are the protruding bones of the hip/pelvis that sit underneath the muscles of the glute and is the part of the body that first contacts the saddle. Everyone has a different width and the importance for a cyclist in finding the exact width is critical for long-term health and cycling enjoyment.Excessive weight/pressure on the soft tissue can lead to health issues such as tumors, genital numbness and even erectile dysfunction due to Pudendal nerve compression and or crushing and or blocking of the Pudendal artery.SADDLE DESIGN—The rear area of a saddle is where the Ischial Tuberosities should rest. This area of the saddle comes in one of two shapes, either (a) flat, or (b) curved. This is where the cyclist should apply most of their weight. The most important item is for the cyclist to minimize the amount of pressure to their soft tissue, in other words, the correct saddle width and saddle shape is paramount in preventing as much of the cyclists' soft tissue from coming into contact with the saddle. Ideally, the majority of contact with the saddle will come from contact of the cyclists' Ischial Tuberosity, the Ischial Ramus and Inferior Ramus of Pubis.This Ischial Tuberosity measuring tool can measure any/all types of cyclists and can be used to measure any/all saddles where a saddle(s) that the bicycle shop carries can be recommended to the cyclist. It is important to note that the recommended saddle(s) will be the correct fitting saddle(s) for the cyclist.This saddle fit system is comprised of impression foam pad(s) that are attached to an organic or inorganic substrate that supports the cyclists weight. Also included are 2 ferrous, non-ferrous or non-metallic balls as well as a detached Vernier caliper measuring device.The cyclist sits and centers themselves on the saddle fit system. The bike fitter then has the cyclist stand thereby leaving 2 indentation impressions on the impression foam. The bike fitter then takes the 2 balls and drops one onto each side of the impression foam pad. Due to the natural force of gravity, these balls will self-center into the exact center-point of each Ischial Tuberosity impression left by the cyclist.The bike fitter will then take the supplied detached calipers and measure the distance from center-point of each ball. This dimension will be noted, shown and discussed with the customer who will then decide on a preferred saddle(s) shape and material.The bike fitter will then show the cyclist preferred saddles by laying the calipers over the top of each saddle and centering the tips of the caliper where the cyclists' Ischial Tuberosities will be contacting the saddle. A follow-on conversation regarding best-fit/best-usage of a recommended saddle based on (a) cyclists' flexibility, (b) cyclists' body shape and conditioning, (c) saddle width and (d) saddle shape can then be held with the cyclist.SIZING THE SADDLE—When the caliper is layed on top of the rear of the saddle, the drop from the Ischial Tuberosity to the top of the saddle can be easily seen and shown to the cyclist. In most cases, the difference between a flat saddle vs a curved saddle is one size difference where the curved saddle usually requires one size wider than the flat top saddle. This is important for a healthy perineum and the correct saddle sizing is easily shown with this tool. Too much of a drop between the ideal placement of the Ischial Tuberosity and contact with the saddle can cause an excessive amount of pressure to be applied to the cyclists' soft tissue.

摘要:
A system and method for collecting and analyzing integrated circuit test vehicle test data by identifying various blocks of circuitry through at least two different intersecting test paths. In one embodiment, the process test circuits may be arranged in a matrix format and connected so that they may be tested along rows or columns. When a failure along a specific row and a specific column is identified, the process test circuit at the intersection may be identified as the failure point.
摘要:
A system and method for collecting and analyzing optical inspection results obtained during the manufacturing process and comparing those results to actual functional results of a specially designed test vehicle integrated circuit. The test vehicle integrated circuit allows failures to be localized to very small areas, which allows more accurate correlation between inspection faults and functional failures. The correlation of inspection faults to actual functional failures is used to change the sensitivity settings for an optical inspection system to more accurately detect defects that are likely to be functional failures.

An interior weld for furniture having a tubular member is disclosed. The weld has a first tubular member and a second tubular member. The first tubular member is adapted to receive the tubular second member. An edge of the tubular second member contacts an inner surface of the first tubular member. A weld is formed on the inner surface of the first tubular member at the contact point where the second tubular member contacts the first tubular member. There is a weld at that contact point which immovably attaches the second member to the first member.

A signal deskew circuit is provided, which includes first and second signal branches, each branch extending between a start location and a respective end location. Each signal branch includes a send path and a return path, which have substantially the same propagation delays. An adjustable delay buffer is coupled in the send and return paths of a first of the signal branches and has a delay, which is adjustable based on a respective adjust signal. A skew sensor coupled to the return paths of the first and second signal branches, which generates the respective adjust signal for the adjustable delay buffer based on a phase difference between signals on the return paths of the first and second signal branches.
