Abstract: Methods and systems are presented for providing a token exchange framework that enables exchanges of reward tokens corresponding to different reward systems and/or different merchants. The token exchange framework includes a blockchain for storing transaction data associated with transactions of reward tokens. During the onboarding process, reward systems associated with different merchants may be connected to the blockchain of the token exchange framework via one or more bridges. Reward tokens may be issued to represent reward data corresponding to the different reward systems, and can be freely exchanged within the token exchange framework via the blockchain. When a transaction for redeeming a reward is received, reward tokens in the blockchain can be converted into reward data corresponding to the merchant's reward system and process the transaction with the merchant using the converted reward data.

Abstract: According to an embodiment, a light emitting diode (LED) nail dryer comprises a cover having a front surface and a rear surface, the rear surface having a rear opening, a bottom plate coupled with the cover and having a bottom opening extending to the rear opening, an internal body formed on the bottom plate in the cover and having a plurality of sockets, and a plurality of LED panels. The plurality of sockets of the internal body may be arranged in a dome shape. Each of the plurality of LED panels may be detachably fitted into a respective one of the plurality of sockets via at least one magnet or at least one fitting structure.

Abstract: A method and apparatus for performing a fragmentation assessment of a material including fragmented material portions is disclosed. The method involves receiving two-dimensional image data representing a region of interest of the material, and processing the 2D image data to identify features of the fragmented material portions. The method also involves receiving a plurality of three dimensional point locations on surfaces of the fragmented material portions within the region of interest, identifying 3D point locations within the plurality of three dimensional point locations that correspond to identified features in the 2D image, and using the identified corresponding 3D point locations to determine dimensional attributes of the fragmented material portions.

Abstract: An optical substrate possesses a structured surface that enhances luminance or brightness and reduces chatter phenomenon. A structured surface is provided, in which some of the valleys (low valleys) are coplanar to the surface of the underlying support layer and other valleys (high valleys) are not coplanar on the support layer. The low valleys have bottom thickness that is substantially smaller than that of the high valleys. The distance from the valleys to the support layer remains substantially similar for a first number of adjacent valleys, but is substantially zero for a second number of adjacent valleys after every n-th adjacent valleys.

Abstract: An optical substrate possesses a structured surface that enhances luminance or brightness and reduces the effects of structural defects on perceived image quality. User perceivable image cosmetic defects caused by manufacturing or handling, can be masked by introducing structural irregularities in the optical substrate, which may be non-facet flat sections or in-kind to the defects. Optical defects caused by non-facet flat sections in the prism structure of the optical substrate (e.g., flat-bottom valleys with a certain valley bottom thickness above the base layer, and/or flat-top peaks, and/or openings in the optical substrates that expose flat sections of underlying base layer) can be masked by providing distributed in-kind non-facet flat sections (e.g., flat-bottom valleys, and/or flat-top peaks, and/or openings exposing sections of underlying base layer), to diffuse the prominence of the original defects with the introduced irregularities.

Abstract: An optical substrate having a structured surface that enhances brightness and reduces moiré effect. The optical substrate has a three-dimensionally varying, structured light output surface that comprises an irregular prismatic structure. The irregular prismatic structure may be viewed as comprising longitudinal prism blocks or rows thereof, arranged laterally defining peaks and valleys. Adjacent peaks, adjacent valleys, and/or adjacent peak and valley may be parallel or non-parallel, in an orderly, semi-orderly, random, or quasi-random manner. The lateral adjacent peaks, adjacent valleys, and/or adjacent peak and valley are not parallel. The adjacent irregular prism blocks may be irregular longitudinal sections having the same length, or random or quasi-random irregular sections having different lengths. The facets of each prism block may be flat, or curved (convexly and/or concavely).

Abstract: A low loss suspended substrate coupler includes a substrate having a first transmission line disposed on a topside of the substrate and a second transmission line disposed on the bottom side of the substrate, thereby providing broadside transmission line coupling. To provide closer mode velocity matching, the coupler has capacitive loading or coupling to ground at discrete intervals between the two transmission lines. The capacitive loading is formed by integrating stubs in each transmission line at pre-determined intervals, each of which is opposite a corresponding one of a plurality of ground stubs on the other side of the substrate. The ground stubs are connected to ground at the outer edge of the coupler area with substrate vias or directly to the coupler housing.

Abstract: A system and method for grouping and editing items directly on a display screen without accessing a dialog box. A box is displayed for grouping a plurality of items. These items are comprised of various fields of information. At least one field is selected for grouping the items. After the field is selected, the field is placed onto the box. The selected field is then displayed in the box. After the field is displayed in the box, the items are grouped by the selected field. After grouping the items by the selected field, the items are displayed as grouped by the selected field. The tasks are repeated for each field remaining if nesting of groups is desired. Items can be edited directly on the display screen by selecting an item from a first field group. The item is then moved to a second field group. As the item moves to the second field group, a message is displayed indicating the status of the item if the item is placed in the second field group. The item is then placed in the second field group.
