  • Patent number: 10379754
    Abstract: A device includes a memory device and a controller. The controller is coupled to the memory device. The controller is configured to, in response to receiving a request to perform a memory access at the memory device, determine that the memory device has a characteristic indicative of a temperature crossing. The controller is also configured to, in response to determining that the memory device has the characteristic indicative of the temperature crossing, determine that the memory device satisfies an availability criterion. The controller is further configured to, in response to determining that the memory device satisfies the availability criterion, increase a temperature of the memory device by performing memory operations on the memory device until detecting a condition related to the temperature.

  • Patent number: 9056060
    Abstract: An adhesive composition which lacks functional groups containing reactive hydrogen moieties and contains no post-polymerization chemical crosslinker finds use in transdermal drug delivery systems. The invention enables the administration of drugs containing a reactive functional group, which drugs have heretofore not been able to be administered by the transdermal route using conventional acrylic adhesives.

  • Patent number: 7375175
    Abstract: A dispersion of polymer particles, the particle containing, on average, one or more living radicals each, the radicals not being chemically protected. Further disclosed is a free radical polymerization process resulting in a dispersion containing polymer particles having on average one or more living radicals. The process involves carefully regulating the polymerization conditions to produce small size particles under monomer-starved conditions containing, on average, more than one living radical in every particle. These living polymer radicals can be further reacted to form polymers with a controlled architecture.
