Abstract: Methods, systems, and devices for a wearable ring device are described. In some cases, the wearable ring device may include an outer housing defining a first outer surface of the wearable ring device, an inner housing defining an inner surface of the wearable ring device, and a crown feature extending from at least a portion of the outer housing and defining a second outer surface of the wearable ring device. The wearable ring device may also include a first set of electrodes positioned at least partially within the crown feature, where the first set of electrodes define at least a portion of the second outer surface, and a second set of electrodes positioned at least partially within the inner housing, where the second set of electrodes define at least a portion of the inner surface.

Abstract: An embodiment in accordance with the present invention provides a device and method for performing Descemet's membrane endothelial keratoplasty (DMEK). The device includes a tray for loading a corneal graft, a permeable cap, and a handle for facilitating delivery of the corneal graft into the eye of the recipient. The tray is configured such that the corneal graft is tri-folded on the tray or folded on the donor cornea. The permeable cap allows for hydration and protection of the graft during transit. When it is time to deliver the corneal graft into the eye of the recipient, the tray can be loaded onto the handle after the caps are be removed. A method according to the present invention includes a corneal graft being loaded onto the tray, covered with the permeable cap, and transmitted to the facility doing the corneal transplant.

Abstract: An anti-electrostatic discharge photomask blank for fabrication of an anti-electrostatic discharge photomask is disclosed. The anti-electrostatic discharge photomask blank includes a mask substrate, a conductive layer provided on the mask substrate and an opaque patterning layer provided on the conductive layer. The conductive layer prevents charges of opposite polarity from accumulating on a photomask fabricated from the photomask blank, thus preventing electrostatic discharges on the photomask.

Abstract: A method for optimizing transactions to customers from a list of transactions is described. The method includes generating a frequency distribution of scores for each offer based on at least one constraint, determining a score threshold based on the frequency distribution of scores, and adding or removing transactions from the list of transactions based on the score threshold.

Abstract: A hand held electronic game having sensors requiring the user to perform functions similar to those required during the activity simulated by the game. In a hand held electronic bowling game, both finger-movement sensors and game-moving sensors require the user to grip and swing the game housing much like swinging a bowling ball while finger-receiving sensors measure movement in the fingers and game housing-movement sensors measure the forcefulness and speed of the user's swing with the ball. The sensors include printed circuit boards and the game-moving sensor can utilize a LED and a photodiode along with a periodically transparent extension, which moves between the LED and the photodiode to determine the force of the swing by centrifugal force.
