  • Patent number: 10303338
    Abstract: This disclosure describes techniques for appending representations of handwritten inscriptions into electronic books, such that electronic books may be customized through the use of inscriptions akin to physical books. To append inscriptions into physical books, a user may provide an inscription on a physical medium. An image of the physical medium including the inscription may be obtained, and the image may be embedded into contents of an electronic book, thus creating a copy of the electronic book that includes a custom inscription in addition to the book contents.

  • Publication number: 20190158419
    Abstract: Commitments against various resources can be dynamically adjusted for customers in a shared-resource environment. A customer can provision a data volume with a committed rate of Input/Output Operations Per Second (IOPS) and pay only for that commitment (plus any overage), for example, as well as the amount of storage requested. The customer can subsequently adjust the committed rate of IOPS by submitting an appropriate request, or the rate can be adjusted automatically based on any of a number of criteria. Data volumes for the customer can be migrated, split, or combined in order to provide the adjusted rate. The interaction of the customer with the data volume does not need to change, independent of adjustments in rate or changes in the data volume, other than the rate at which requests are processed.

  • Patent number: 5252967
    Abstract: A two wire/three wire utility data communications system for remotely reading utility meter registers. In the two wire version, a hand-held reading unit is inductively coupled over two wires via a port located remotely from a meter register. Alternatively, a meter interface unit (MIU) may be connected directly to the register via three wires. Each register includes one or more wheel position encoders. An AC interrogation signal is applied by the reading unit to encoder circuitry at the meter which powers the circuitry and causes the position of each encoder wheel to be read. In the two wire mode, register display information (e.g. the current meter reading) is transmitted back to the reading unit by varying the load (impedance) presented by the register side of the circuit. This causes a corresponding variation of the amount of current drawn from the reading unit. The current-modulated signal is decoded by the reading unit and converted into a register reading.

  • Patent number: 4221676
    Abstract: A process for removing suspected heavy metal contaminants from a manganese-arsenic activated, zinc orthosilicate phosphor comprises contacting the phosphor, in an aqueous slurry, with an organic chelating agent such as an alkali metal salt of ethylenediamine tetraacetate and subsequently rinsing, filtering, drying and sieving the phosphor and baking the sieved phosphor.
