Dead band self-test method of three-self FOG INS

As the demand of safety-critical applications (e.g., automobile electronics) increases, various radiation-hardened flip-flops are proposed for enhancing design reliability. Among all flip-flops, Delay-Adjustable D-Flip-Flop (DAD-FF) is specialized in arbitrarily adjusting delay in the design to tolerate soft errors induced by different energy levels. However, due to a lack of testability on DAD-FF, its soft-error tolerability is not yet verified, leading to uncertain design reliability. Therefore, this work proposes Delay-Adjustable, Self-Testable Flip-Flop (DAST-FF), built on top of DAD-FF with two extra MUXs (one for scan test and the other for latching-delay verification) to achieve both soft-error tolerability and testability. Meanwhile, a built-in self-test method is also developed on DAST-FFs to verify the cumulative latching delay before operation. The experimental result shows that for a design with 8,802 DAST-FFs, the built-in self-test method only takes 946 ns to ensure the soft-error tolerability. As to the testability, the enhanced scan capability can be enabled by inserting one extra transmission gate into DAST-FF with only 4.5 area overhead.

Measurable Change

Vaginitis is a common disorder among women of varying ages that arises from a change in the normal pH balance of vaginal bacteria or an infection. Characteristic symptoms of itching, irritation, and odor cause considerable discomfort and increase the risk of contracting other sexually transmitted infections. Because of the sensitive and personal nature of the condition, some women may be reluctant to seek treatment. This behavior not only fails to solve the problem but may also delay medical treatment and result in additional medical complications. The pH changes associated with vaginitis and vaginosis, which are characterized by the presence or absence of inflammation, respectively, are well known but can vary. For example, bacterial vaginosis and trichomoniasis infection will raise vaginal pH above 4.5, while vulvovaginal candidiasis does not result in any measurable change to pH. Nonetheless, diagnostic tools relying on pH measurement are a valuable approach from which additional testing and treatment may be launched. Here, we focused on the use of a vaginal self-test tool and tested 50 patients, including pregnant women. When used according to the instructions, the Hygeia Touch Self-Testing Kit for Vaginal Infection demonstrated over 88% accuracy compared to a clinical diagnostic workup, with a sensitivity of 87% and a specificity of 89% in the patients where the swab was correctly interpreted. This study demonstrated an effective self-test method with high acceptability among women that provided them with greater autonomy regarding health management.
