    摘要： An electronic circuit having built-in self testing capabilities for optimizing power consumption. Typically, the electronic circuit includes a component circuit that operates at some known or unknown optimal operating power level. Further, the electronic circuit includes a power supply coupled to the component circuit such that the power supply provides power to the component circuit. Further yet, the electronic circuit includes a test circuit coupled to the component circuit and coupled to the power supply. The test circuit is operable to monitor the power supplied to the component circuit and operable to control the power supply. In an iterative manner, the test circuit reduces the power supplied to the component circuit until the power supplied to the component circuit is operating at the optimal operating power level.

    摘要： A printer has a print head with multiple nozzles and firing elements for corresponding nozzles. The print head receives one or more power supply inputs to operate the firing elements. The print head has power supply fault protection circuitry to guard against harmful and destructive effects on firing resistors resulting from power supply fluctuations. The power supply fault protection circuitry is integrated into a pen-based chip that also forms the firing elements and optionally the firing logic.

    摘要： There is provided a molecular sieve coated with a non-oxide ceramic. The molecular sieve may be a zeolite, such as ZSM-5, and the ceramic coating may be, e.g., boron nitride. The coated molecular sieve may be prepared by contacting the molecular sieve with a ceramic precursor material comprising a thermally decomposable material, such as polyborazylene, and thermally decomposing this thermally decomposable material. The coated molecular sieves may be used as organic conversion catalysts. The non-oxide ceramic coating may alter or enhance the shape-selective properties of the molecular sieve by providing a diffusion barrier to molecules.
