Patent

Lakshmikanthan C., “A Handheld device to capture Fundus images”, 2016.[Abstract]


The present invention relates to a hand held device used to capture fundus images. More particularly the intention provides a low cost hand held device to image entire fundus either it is central or peripheral. The invention is smart phone based hand held device capable of capturing regions of peripheral most retina such as ora serrata and further till pars plana apart from central fundus. Advantageously, the present invention is operated by single hand.
(FR) La présente invention concerne un dispositif portatif utilisé pour capturer des images du fond de l'œil. Plus particulièrement, l'invention concerne un dispositif portatif économique permettant de former l'image de l'intégralité du fond de l'œil, qu'il soit central ou périphérique. L'invention est un dispositif portatif basé sur un téléphone intelligent susceptible de capturer des régions de la rétine la plus périphérique telle que l'ora serrata ou encore pars plana en plus du centre du fond de l'œil. De manière avantageuse, la présente invention est actionnée d'une seule main.

India, being the fastest growing economy, has an ever increasing demand for transportation leading to increased competition between the manufacturers. Boundaries of the various parameters were pushed for saving time to market and cost. Among these parameters, the in-cabin noise level plays a major role in defining the comfort of the passengers. This article assesses the in-cabin noise levels of one of the entry level vehicles from a manufacturer. The whole study was conducted in two parts. The first part involving overall measurement of the noise levels in the vehicle and the second part is to study the major noise transfer mechanism. An acceleration test was first conducted to study the overall noise level. Various test conditions are designed to predict the major contributor of the in-cabin noise as part of the second step. The major contributing factors are engine noise and road and tyre interaction noise. Tests were repeated to eliminate the road noise. Noise levels measured in the cabin show that the airborne noise is the major contributor.

K., “Smartphone-based fundus camera device (MII Ret Cam) and technique with ability to image peripheral retina.”, European journal of ophthalmology, vol. 26, no. 2, pp. 142–144, 2015.[Abstract]


Purpose
To demonstrate an inexpensive smartphone-based fundus camera device (MII Ret Cam) and technique with ability to capture peripheral retinal pictures.

Methods
A fundus camera was designed in the form of a device that has slots to fit a smartphone (built-in camera and flash) and 20-D lens. With the help of the device and an innovative imaging technique, high-quality fundus videos were taken with easy extraction of images.

Results
The MII Ret Cam and innovative imaging technique was able to capture high-quality images of peripheral retina such as ora serrata and pars plana apart from central fundus pictures.
