The tunable filter placed in front of the detector to make the interferometer more sensitive and accurate for reading various samples for diagnosis. Optical Coherence Tomography (OCT) system and apparatus of this instant application is very useful for diagnosis and management of ophthalmic diseases such as retinal diseases and glaucoma etc. Instant innovative OCT diagnostic system leverages advancements in cross technological platforms. Both the Michelson interferometric system and Mach-Zehnder interferometric system presented in this application could be used for the OCT imaging, which includes biological OCT imaging, medical OCT imaging, ophthalmic OCT imaging, corneal OCT imaging, retinal OCT imaging, and the like.
A projectile launching apparatus includes a bolt (for chambering a projectile) and a bolt valve with a gas passageway for communicating the gas from a chamber housing to a breech assembly. Gas received within the gas chamber is compressed by a piston and communicated through the breech assembly to a projectile. The compressed gas expands in the barrel, thereby propelling the projectile out of the barrel in a single stroke of the piston. The bolt may be returned to an initial position by a magnet and / or spring that is coupled to the valve, and the piston may be returned to an initial position by way of vacuum pressure. The bolt valve may also include a mechanical retention element such as a sear and a release pin. The sear may the bolt in a first position until the piston from the compressor has moved sufficiently to push the release pin.
Disclosed is a portable business cardscanner for scanning, storing and displaying an encoded image of a business card. The portable business cardscanner includes a casing, a scanner, at least one memory, at least one input device and a display device. The scanner is configured to scan the business card to generate an encoded image thereof. The at least one memory is configured to store the encoded image of the business card. The at least one input device is configured to retrieve the encoded image from the at least one memory and add a labeling data to the encoded image. The display device is configured to display the encoded image of the business card.
A support structure for a user's back includes a body member and at least one air interface. The body member includes a plurality of members, such as a middle support member and a pair of side support members. The pair of side support members is configured with the middle support member such that a first side support member and a second side support member of the pair of side support members are configured with the middle support member at a pre-determined angle with respect to the middle support member. The plurality of members includes a base layer and a cushion layer disposed on the base layer. The at least one air interface is disposed on each member of the plurality of members to inflate and deflate the cushion layer of the each member of the plurality of members. Further, a support structure package is configured to cover the support structure.
