Abstract: A gaming machine including a secondary processor coupled to a player tracking system for tracking game play of a patron using a virtual player loyalty card is described. A virtual player loyalty card can be created by associating an existing physical player loyalty card with a newly created mobile loyalty card account. The mobile card can be virtually inserted into an electronic gaming machine when a portable electronic device with an associated mobile application is in the vicinity of an electronic gaming machine. Once the mobile card is virtually inserted into the gaming machine, the patron's game play at the gaming machine can be tracked.

Abstract: Systems and methods are disclosed to provide a fairing block that couples a sonar transducer to a hull of a mobile structure. The fairing block includes a leading edge that diverts water and bubbles in the water laterally around the fairing block and the sonar transducer. A bottom of the leading edge provides a substantially undisturbed water flow over a working face of the sonar transducer while the mobile structure is in motion. The bottom of the leading edge may include a curvilinearly chamfered surface that helps prevent cavitation along the working face of the transducer. One or more lateral cutouts are disposed behind the leading edge to expose lateral sides of the sonar transducer to the water. The lateral sides of the sonar transducer may be metallic and exposed to water by the lateral cutouts, thereby dissipating heat generated within the sonar transducer to the water.

Abstract: An auto allele caller executed in a computer system for identifying alleles from a trace is described. The auto allele caller applies a typical shape of an allele for a marker to the trace to identify potential allele calls that match to the typical shape of the allele at the marker and assigns a quality factor to the allele calls.
