Abstract: A method, an apparatus, and a computer program product for modulating optics in a display are provided. An apparatus forms a plurality of zone plates in a liquid crystal using electric fields. Each zone plate has a center, and the centers are aligned along a first axis of the display. The apparatus moves the plurality of zone plates in a first direction along a second axis of the display different from the first axis of the display, while maintaining alignment of the centers of the plurality of zone plates along the first axis. Such movement is provided through repositioning of electric fields through the liquid crystal.

Abstract: The various embodiments include a near-eye display having a transmissive display and a diffractive micro-lens array. The transmissive display may be positioned relative to the diffractive micro-lens array so that the distance between the transmissive display and the diffractive micro-lens array is be approximately equal to focal length of the diffractive micro-lens array. The transmissive display may also be positioned relative to the diffractive micro-lens array so that a percentage of light emitted from the transmissive display is diffracted by the micro-lens array and collimated into focus on a retina of a human eye. The transmissive display may be further positioned relative to the diffractive micro-lens array so that light from a real world scene passes through transparent portions of the transmissive display and is diffracted by the micro-lens array out of focus of the human eye.

Abstract: The subject invention is a beverage garnishing system that includes an improved straw with water-soluble garnishing agents to impart garnishing to beverages. The system allows for the easy addition of custom garnishings of choice to any kind of beverage in a germ free manner which allows for uniform regulation of the amount and kind of ingredients.

Abstract: A first sensor may be configured to measure a sensed amount of a physiological parameter and to generate a first signal based on the sensed amount of the physiological parameter measured by the first sensor. A second sensor may be configured to measure a temperature and to generate a second signal based on the temperate measured by the second sensor. A housing may have heat-generating electronics including a processor that may be configured to determine an overall amount of the physiological parameter based on the first signal generated from the first sensor and the second signal generated from the second sensor. The second sensor may be thermally insulated from the heat-generating electronics.
