Appl. No.:

12/798324

Donald R. Korb - Boston MA, US

International Classification:

A61B 3/14
A61B 3/10

US Classification:

351206, 351205, 351221

Abstract:

Ocular surface interferometry (OSI) devices, systems, and methods are disclosed for measuring a tear film layer thickness (TFLT) of the ocular tear film, including lipid layer thickness (LLT) and/or aqueous layer thickness (ALT). The measured TFLT can be used to diagnosis dry eye syndrome (DES). In certain disclosed embodiments, a multi-wavelength light source can be controlled to illuminate the ocular tear film. Light emitted from the multi-wavelength light source undergoes optical wave interference interactions in the tear film. An imaging device can be focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in a first image. The imaging device can also be focused on the lipid layer of the tear film to capture a second image containing the background signal(s) present in the first image. The second image can be subtracted from the first image to reduce and/or eliminate the background signal(s) in the first image to produce a resulting image.

International Classification:

Abstract:

A tire-condition ascertaining appliance for ascertaining a condition of a tire includes a housing defining an inner compartment that is substantially hollow. The housing is positioned within an inflation chamber defined between sidewalls of the tire and the rim. The appliance includes an electronics platform received within the inner compartment of the housing. The electronics platform ascertains a fluid condition of the tire and generates fluid-condition data, and processes the fluid-condition data. An antenna is connected to the electronics platform. The antenna receives the fluid-condition data indicative of the fluid condition and transmits the fluid-condition data to a remote location.
