Among other things, a system includes a card-game table that includes visually defined regions on a surface of the card-game table to accommodate one or more card hands of each of one or more participants in addition to one or more separate card hands of a house entity. The illumination device includes a body formed of a thermally-conductive material that includes a planar heat transfer surface and a fastener that is compatible with a base that couples the body to the light fixture. The mover of said linear motor comprising at least one section of soft magnetic material and at least one permanent magnet, the at least one section of soft magnetic material and the at least one permanent magnet being aligned in an axial direction of the mover, wherein a polarization vector of said at least one permanent magnet is directed axially. The mobile station may periodically combine a Comfort Noise Parameter message with a MAHO-related Channel Quality Measurement message and transmit the combined messages to the base station while in the DTX_Low state. As a result, a seal is formed and maintained between the first object and the second object. The optimized persistent messaging method and system also prioritizes delivery services that are capable of delivering a message according to prioritization criteria from a variety of possible sources.
