Abstract: In accordance with some embodiments, a physical game element such as a wagering chip or a playing card may be utilized to implement a promotion scheme on an electronic game table (e.g., using RFID or optical imaging technology). During a game it may be determined whether the element is associated with special functionality (e.g., entitles the player to a payout multiplier, special payout table, bonus prize or other benefit). The special functionality may have been previously associated with the element or associated with the element during the game (e.g., dynamically and/or randomly). In accordance with some embodiments a player is not able to readily discern the special functionality by a physical inspection of the physical game element and is only notified of the special functionality once the physical game element is used in a qualifying action (e.g., during a wager at an electronic game table).

The receptacle is configured to facilitate electrically connecting to the fuel cell stack, and the connector is receivable within the receptacle for electrically connecting the circuit board to the fuel cell stack. The connector is elastically deformable to facilitate operative positioning of the connector within the receptacle, and to facilitate an interference fit of the connector within the receptacle against a surface defining, at least in part, the receptacle to secure the connector within the receptacle, with the connector electrically connected to a fuel cell plate of the fuel cell stack.

Abstract: A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held ‘TRUE’ if they are already ‘TRUE’ when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.

Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

Notably, the sunscreen active may provide enhanced photoprotection at relatively low concentration levels when present with the carrier, including the amphiphile monolayer, and the acrylic film former polymer.
