Abstract: The present subject matter facilitates chaining of multiple serial peripheral interface (SPI) compliant devices without requiring a bulky clock tree. Generally, in a serial clock distribution scheme as described herein, a fixed pulse based output cock (SCLK_OUT) is synchronized with the data output (SDO) from a respective device in the chain. The SCLK_OUT signal is connected to the SPI clock input (SCLK) of the following downstream device, and SDO is connected to the data input (SDI) of the respective downstream device. This allows the SCLK from the SPI master device to propagate through a theoretically unlimited count of devices in series. The master can resynchronize the MISO data from the SDO of the last part in the chain with the SCLK_OUT signal of the last device in the chain.

The main portion has a lip and at least one damping feature. The lip extends around at least a portion of a periphery of the main portion. The hinge portion is disposed between and connects the main portion and the attachment portion. When the attachment portion is attached to the housing, the main portion is configured to move between a closed position and an opened position. When the main portion moves from the opened position to the closed position, the at least one damping feature is configured to engage the housing prior to the lip of the main portion and thereby dampen noise created when the lip of the main portion engages the housing.

Abstract: A client device, a system and a method for enabling financial transactions for electronic gaming machines are described. The client device includes an electronic gaming machine processor, a printer, a printer sharing module, one or more wireless communication modules, a slot cabinet, a backend server, and a master gateway. The slot cabinet houses the electronic gaming machine, printer, and a wireless communications module.

Abstract: The present invention is directed to virus-like particles (VLPs) which are engineered to present epitopes from Staphylococcus aureus (SA), preferably autoinducing peptides (AIPs) which regulate quorum-sensing dependent virulence in this pathogen, or epitopes from SA toxins and leukocidins. These VLPs may be used to provide immunogenic compositions and efficacious vaccines. In a mouse model of SA dermonecrosis, vaccination with AIP-containing VLPs or SA toxin-containing VLPs induces protective immunity to limit the pathogenesis of SA infection and promote bacterial clearance.
