  • Patent number: 12622213
    Abstract: A cassette handle includes a body, a first foot, and a second foot. When in a position following the application of a force to the body, the first foot and the second foot can engage a cassette for semiconductor wafers or samples. When in another position following the removal of the applied force, or absent an application of a force to the body, the first foot and the second foot are disengaged from the cassette. Recesses and/or markers on the first foot and the second foot indicate when the first foot and the second foot are correctly engaged with the cassette. Where the cassette handle includes both recesses and markers, the markers may be inset within the recesses.

  • Patent number: 10579566
    Abstract: A point-of-sale (POS) device includes a processor, a universal serial bus (USB) hub, two switches, and an external connector that connects the POS device to a secondary device with its own second processor. In a primary mode, the processor is connected to a host connector of the USB hub and the secondary device is connected to a first peripheral connector of the USB hub via the external connector. In a secondary mode, the processor is connected to the first peripheral connector of the USB hub and the secondary device is connected to the host connector of the USB hub via the external connector. The processor controls the switch from the primary mode to the secondary mode, and vice versa, by transmitting control signals to control pins of the two switches, and optionally by transmitting a reset signal to a reset pin of the USB hub.

  • Patent number: 8383102
    Abstract: Lysostaphin is a bacteriocin secreted by S. simulans to kill S. aureus, and has been shown to also be a potent antimicrobial for many antibiotic-resistant strains of S. aureus. By adding a ˜13 amino acid protein transduction domain (PTD) from the HIV-TAT protein to lysostaphin to form lysostaphin-PTD, both extracellular and intracellular forms of S. aureus and MRSA are killed in all (multiple) cell types examined.
