Simple technique for measuring source reflection coefficient while characterizing active devices

Noninvasive light-reflection technique for measuring soft-tissue stretch.

A novel, to our knowledge, sensor for measuring the stretch in soft tissues such as skin is described. The technique, which is a modification of two-dimensional polarization imaging, uses changes in the reflectivity of polarized light as a monitor of skin stretch. Measurements show that the reflectivity increases with stretch. Measurements were made on guinea pig skin and on nonbiological mater...

A technique based on the equivalent source method for measuring the surface impedance and reflection coefficient of a locally reacting material

A technique based on equivalent source method (ESM) is developed in this paper for measuring the surface impedance and reflection coefficient of a test material. The technique requires the measurement of complex pressures on two parallel planes between the sound source and the test material. If the sound source has rotational symmetry, the measurement on two parallel lines is sufficient. The so...

Simple Surgical Technique for Ingrown Toenail Surgery

Background: Ingrown toenails are a common condition which, when recurrent and painful, are often treated surgically. This study proposes a new simple surgical technique for ingrown toenails with good results.Method: We selected 150 patients with 185 affected toes who were surgically treated by our techniques carried out from April 1995 to March 2004. This technique consisted of marginal n...

A simple radial diffusion technique for measuring selectivity of proteinuria.

Sizing rings: a simple technique for measuring intracranial lesions.

There is now a need to measure accurately the sizes of intracranial lesions, particularly arteriovenous malformations (AVMs) and aneurysms. Until recently, this was not necessary, because the treatment options available for these lesions were limited to open surgery or nothing. Aneurysm size, for example, was relatively unimportant; what was important was only the issue of its location, whether...
