Abstract: A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic devices comprise a gate, a channel, and an obstruction. The gate comprises at least one chamber whose volume increases with fluid pressure. A high-pressure state of the gate corresponds to a first chamber size and a low-pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size. The obstruction controls a rate of fluid flow within the channel based on the fluid pressure in the gate. The obstruction induces at most a first flow rate of fluid in the channel in accordance with the low-pressure state of the gate, and at least a second flow rate of the fluid in the channel in accordance with the high-pressure state of the gate.

Abstract: Examples are provided for measuring force applied to a device, such as a stylus tip. An example stylus includes a stylus body, a stylus tip, and the stylus tip including a light emitting device and a compressible light reflecting optic, the light emitting device comprising a light emitter and a light detector, and the compressible light reflecting optic comprising a first reflective layer configured to (i) allow a first portion of light from the light emitting device to pass and (ii) to reflect a second portion of light from the light emitting device, and a second reflective layer, more reflective than the first reflective layer, configured to reflect light from the light emitting device, the first layer being spaced from the second layer by a light-transmissive material. A force exerted on the stylus tip is measurable based at least on a parameter of light received at the light detector.

Abstract: An electronic display comprises a display matrix, an image-correcting layer, and a luminance-correcting layer. The display matrix includes a flat face portion, a curved corner portion, a light-releasing surface, and a series of pixels extending across the flat face portion and around the curved corner portion. Coupled to the light-releasing surface of the display matrix, the image-correcting layer is configured to transmit light released from the flat face portion of the display matrix and to reorient light released from the curved corner portion of the display matrix such that the transmitted light and the reoriented light exit the image-correcting layer substantially in parallel, forming an apparent plane image of the series of pixels. Arranged between the light-releasing display surface and the image-correcting layer, the luminance-correcting layer is configured to deflect the light released from the curved corner portion into an acceptance profile of the image-correcting layer.

Abstract: An optical sensing device can receive a speckle pattern generated by a laser's interaction with acoustically stimulated tissue. A computing device can identify one or more characteristics within the received speckle pattern. The computing device can then identify a match of the one or more characteristics to a user biometric signature stored within a storage device. Based upon the identified match, the system can authenticate a user within a computer system.

Abstract: A gaze accurate video conferencing system includes a screen that alternates between a light-scattering state and a substantially transparent state. A camera is positioned behind the screen and is configured to capture images of a user positioned in front of the screen when the screen is in its substantially transparent state. When the screen is in its substantially light-scattering state, a projector projects a display image on the screen.

Abstract: A data input device for use with an optically rough tracking surface comprising a coherent light source projecting a coherent light beam and an optic positioned in the coherent light beam. The optic alters a wavefront profile of the coherent light beam so that the coherent light beam has a substantially constant phase relative to a plane perpendicular to the beam at a tracking distance from the optic. The coherent light beam is projected onto the tracking surface to reflect a substantially stable speckle pattern. A controller responsive to a detector correlates the substantially stable speckle pattern to track relative movement between the coherent light beam and the tracking surface. The controller suspends tracking of relative movement between the coherent light beam and the tracking surface when the detector detects a boiling speckle pattern.
