  • Publication number: 20240144396
    Abstract: Methods, systems, and computer storage media for providing a concentrate grade recommendation using a concentrate grade optimization engine in a material processing engine of a material processing system. The concentrate grade recommendation refers to a quantified value for concentrate grade that corresponds to an economic value for ore of a mining process. In operation, input data comprising material processing planning data and economic data associated with a recovery process are accessed. The input data is analyzed using a grade recovery relationship machine learning model. The grade recovery relationship machine learning model is trained on historical material processing data features associated with concentrate grade and recovery of the material recovery process. The historical data includes data on produced concentrate (e.g., achieved grades and corresponding recovery). Based on analyzing the input data, a concentrate grade that corresponds to an economic value is generated.

  • Patent number: 11400052
    Abstract: The invention relates to modified release oral formulations of therapeutic agents, including gamma hydroxybutyrate (GHB), paracetamol, codeine or oxycodone, which are resistant to alcohol induced dose dumping. Provided are formulations that have improved resistance to rapid release of the active ingredient in the presence of increasing amounts of alcohol. Also provided are formulations that can reduce or prevent the release of the active ingredient following exposure to alcohol-containing media. The invention also relates to methods of making the formulations, and methods of their use for the treatment of sleep disorders such as apnea, sleep time disturbances, narcolepsy, cataplexy, sleep paralysis, hypnagogic hallucination, sleep arousal, insomnia, and nocturnal myoclonus.

  • Publication number: 20110052684
    Abstract: The present invention relates to a pharmaceutical composition comprising a tablet core comprising a combination of actives selected from the group consisting of bupropion hydrochloride and escitalopram oxalate, bupropion hydrobromide and citalopram hydrochloride, bupropion hydrobromide and escitalopram oxalate, and bupropion hydrobromide and quetiapine fu-marate, and at least one pharmaceutically acceptable excipient, and a control-releasing coat surrounding the tablet core, wherein said composition surprisingly provides for a synchronous release of the combination of active agents in-vitro. The once-daily pharmaceutical composition surprisingly also provides for enhanced absorption of bupropion hydrobromide when administered to a subject in need of such administration.

  • Patent number: 6031749
    Abstract: A switch-mode power converter uses a digital signal processor (DSP) to control operation of power semiconductors through gate drive amplifiers, further using the DSP's internal analog-to-digital converters to measure necessary currents, voltages and timings within the main power circuit. Using values captured by the A-to-D converters, software controlling the DSP manipulates duty cycle and timing parameters of the main semiconductor switches to provide at least three different modes of operation for serving a wide range of lighting loads. This power system reduces the size, cost, and weight, of circuitry needed to operate stage lighting equipment. The DSP's microprocessor eliminates most of the complex and dedicated analog circuitry commonly used for electronic power conversion, and a common power circuit topology provides an identical hardware platform for each luminaire circuit. Overall reliability is enhanced because of the reduction in circuit complexity.
