Abstract: A gaming system compatible with patron-controlled portable electronic devices, such as smart phones or tablet computers, is described. The gaming system can include electronic gaming machines that are compatible to receive both virtual ticket vouchers and printed ticket vouchers that are redeemable for credits on the electronic gaming machines. Information associated with a virtual ticket voucher can be stored on a patron-controlled portable electronic device and then can be wireless transmitted to the electronic gaming machines. The electronic gaming machines can be configured to issue virtual ticket vouchers and printed ticket vouchers that can be redeemed for cash or additional game play on another electronic gaming machine. In one embodiment, the electronic gaming machine can be configured to issue a virtual ticket voucher to a patron-controlled portable electronic device.

Abstract: A robotic cleaner may include a main body, one or more drive wheels coupled to the main body, one or more surface type sensors coupled to the main body, the one or more surface type sensors being configured to receive robotic motor sound reflected from a surface to be cleaned, the robotic motor sound being generated by one or more motors of the robotic cleaner, and a controller configured to determine a surface type based, at least in part, on the reflected robotic motor sound.

Abstract: An integrated circuit including a first circuit, a second circuit, a third circuit, a first complementary pair of transistors, and a second complementary pair of transistors. The first circuit may be configured to generate a first input signal in response to a first control input signal. The second circuit may be configured to generate a first output signal and a second output signal in response to the first input signal and a bias signal. The third circuit may be configured to generate the bias signal in response to a bias input signal. The first complementary pair of transistors may be configured to drive a first series output of the integrated circuit in response to the first output signal. The second complementary pair of transistors may be configured to drive a first shunt output of the integrated circuit in response to the second output signal.
