  • Patent number: 9702271
    Abstract: Apparatus, systems and methods are provided for the improved use of waste heat recovery systems which utilize the organic Rankine cycle (ORC) to generate mechanical and/or electric power from heat sources generating power from biofuel such as biogas produced during the anaerobic digestion process. Waste heat energy obtained from heat source(s) is provided to one or more ORC system(s) which may be operatively coupled to electric generator(s). A heat coupling subsystem provides the requisite condensation of ORC working fluid by transferring heat from ORC working fluid to another process or system, such as anaerobic digester tank(s), to provide heat energy that enhances the production of fuel for the prime mover(s) without requiring the consumption of additional energy for that purpose.

  • Publication number: 20160084115
    Abstract: Systems and methods are provided for the recovery of mechanical power from heat energy sources via multiple heat exchangers and expanders receiving at least a portion of heat energy from a source. The distribution of heat energy from the source may be portioned, distributed, and communicated to the input of each of the heat exchangers so as to permit utilization of up to all available heat energy. In some embodiments, the system receives heat energy from more than one source at one or more temperatures. Mechanical energy from expansion of working fluid in the expanders may be communicated to other devices to perform useful work or operatively coupled to one or more generators to convert the mechanical energy into electrical energy.

  • Patent number: 8727855
    Abstract: Gaming machines, systems and methods for presenting wager-based games having three-dimensional paylines are disclosed. Gaming machines include an exterior housing, master gaming controller, display device, speakers and a network interface. A multi-layer display device that presents three-dimensional paylines includes a display controller that generates or transmits display signals, a first display screen that presents a first visual display and a second display screen that presents a second visual display, where the second display screen is positioned behind the first display screen such that the first and second visual displays combine for a single visual presentation. Each of the first and second visual displays includes symbols, symbol portions, stops and/or designations used to form a three-dimensional payline. A three-dimensional payline can jump from one display screen to the other at least once.

  • Patent number: 8512139
    Abstract: A gaming system including a number of host devices each coupled to one or more gaming machines, wherein content provided by the host device is output on the gaming machine. To output the content provided by the remote host, a host-controlled process that is authenticated by the gaming machine and executed in a secure memory location such that it is isolated from other processes executing on the gaming machine may be utilized. The host-controlled processes can be executed on a processor-based gaming machine with layered displays. The layered displays may include a front screen and back screen that provide actual physical separation between visual representations on the front and back screens. The downloaded content from a host to a gaming machine with layered displays may be monitored to ensure that content needed for each of the display layers is received prior to instantiating the display of the downloaded content via the host-controlled process.
