Abstract: Debris-removing cap includes a cap body having a receiving cavity and an interior surface disposed within the receiving cavity. The cap body is configured to be attached to an optical device such that a mating face of the optical device is disposed within the receiving cavity. The interior surface is configured to face the mating face of the optical device. The debris-removing cap also includes a lens wiper that is coupled to the interior surface within the receiving cavity and extends away from the interior surface toward the mating face of the optical device. The lens wiper moves relative to the mating face when activated by a user of the debris-removing cap. The lens wiper engages a lens of the mating face when activated by the user to remove debris from the lens.

Abstract: Mode size converter including an overlay waveguide having an input end configured to receive light from an optical element. The overlay waveguide has a first refractive index. The mode size converter also includes a signal waveguide that is embedded within the overlay waveguide and has a second refractive index that is greater than the first refractive index. The signal waveguide includes first and second arm segments and a stem segment that form a Y-junction. The first and second arm segments are configured to reduce a modal profile of the light propagating toward the stem segment from the input end of the overlay waveguide. Each of the first and second arm segments has a distal end and a pair of opposite side edges, wherein the pair of side edges extend parallel to each other between the corresponding distal end and the stem segment.

Abstract: Light-coupling structure including a grating coupler that is configured to optically couple with an optical element. The grating coupler has a diffraction grating that extends parallel to a grating plane. The grating coupler is configured to diffract a light beam into first and second diffracted portions when the light beam is effectively normal to the grating plane. The first and second diffracted portions propagate away from each other. The light-coupling structure also includes first and second intermediate waveguides that are optically coupled to the grating coupler and configured to receive the first and second diffracted portions, respectively. The light-coupling structure also includes a common waveguide that is coupled to the first and second intermediate waveguides at a waveguide junction. The first and second diffracted portions propagate within the first and second intermediate waveguides, respectively, and are combined in-phase at the waveguide junction.

Abstract: The present invention relates to a multi-touch display system that supports both multi-touch human input as well as input from a digital pen. The display system has a display panel that is configured to allow human touches along a front surface to be detected and tracked. The display panel also includes a location pattern that preferably covers the viewable areas of the display panel. The location pattern is configured to allow any location within the location pattern to be detected by analyzing a portion of the display pattern that is associated with the particular location. The digital pen is used to “write” on the display panel, wherein such a writing function involves detecting the location where writing occurs and controlling display content that is displayed on the display panel to reflect what is being written.

Abstract: An ultrasonic imaging processing method based on RF data includes the following steps: S1, receiving echo signals which are obtained by sending ultrasound signals; S2, beamforming the echo signals; S3, obtaining the RF data of the echo signals; and S4, directly conducting an ultrasonic imaging process based on the obtained RF data in order to obtain a target image. The ultrasonic imaging processing method and system based on the RF data according to the present application directly conduct ultrasonic imaging treatment based on the obtained RF data of the echo signals in order to obtain the target image. As a result, the system is simple and with no loss of data information. Besides, real-time performance and image quality of ultrasonic diagnose appliance by using such method and system are improved.

Abstract: A method is provided for determining the three-dimensional position of an interaction location within a scintillating crystal at which an high-energy photon produces a plurality of scintillation photons. The method includes the use of a sensor-on-entrance-surface photodetector device to determine a distribution pattern of the scintillation photons in the crystal.
