  • Patent number: 11914541
    Abstract: In example implementations, a computing device is provided. The computing device includes an expansion interface, a first device, a second device, and a processor communicatively coupled to the expansion interface. The expansion interface includes a plurality of slots. Two slots of the plurality of slots are controlled by a single reset signal. The first device is connected to a first slot of the two slots and has a feature that is compatible with the single reset signal. The second device is connected to a second slot of the two slots and does not have the feature compatible with the single reset signal. The process is to detect the first device connected to the first slot and the second device connected to the second slot and disable the feature by preventing the first slot and the second slot from receiving the single reset signal.

  • Publication number: 20080038355
    Abstract: Bioadhesive steroid nanoparticles are used to prepare a rapidly disintegrating solid oral dosage form of steroid. The bioadhesive steroid nanoparticles have a bioadhesive polymer surrounding the steroid nanoparticles and with an average diameter of less than 1000 nm. Hence, the solid oral dosage form, containing the bioadhesive steroid nanoparticles, a disintegrant and an effervescent agent, instantly disintegrates in the oral cavity and adheres on the periodontal pocket and oral mucosa to release steroid rapidly.
