  • Power Gating in an Electronic Device
    Publication number: 20150355662
    Abstract: An electronic device 2 has circuitry 4 which operates in a first voltage domain 6 supplied with a first voltage level VDD1 and a reference voltage level. A voltage regulator 14 generates the first voltage level VDD1 from a second voltage level VDD2 higher than the first voltage level VDD1. At least one power gate 20, 30 is provided for selectively coupling the circuitry 4 to one of the first voltage level VDD1 or the reference level. The control signal 22 for the power gate 20, 30 is generated in a second voltage domain supplied with a higher voltage level VDD2 or VDD3 derived from the second voltage level VDD2 supplied to the voltage regulator 14. Hence, an existing high voltage source within the device 2 can be reused for applying a boosted voltage to power gates to improve efficiency of power gating.

  • Controlling voltage generation and voltage comparison
    Patent number: 9170282
    Abstract: An integrated circuit has voltage generating circuitry for generating an on-chip voltage from a supply voltage in response to clock pulses. Clock control circuitry controls transmission of the clock pulses to the voltage generating circuitry. The clock control circuitry receives a reference voltage and a digital offset value comprising a binary numeric value identifying an offset. The clock control circuitry suppresses transmission of the clock pulses if the on-chip voltage is greater than the sum of the reference voltage and the offset identified by the digital offset value, to reduce power consumption. The offset can be tuned digitally to vary the average level of the on-chip voltage. A similar digital tuning mechanism may be used in a clocked comparator to compare a first voltage with a digitally tunable threshold voltage.

  • Chemical Injection To Increase Production From Gas Wells
    Publication number: 20150285046
    Abstract: There is described a chemical injection system for a natural gas well. An instrument monitors the production of gas from the well and the flow of chemicals injected into the well. The instrument controls the on and off time of a chemical injection pump that is attached to a chemical injection tank. The control is based for certain chemicals such as a surfactant on the gas flow rate in the production piping. The user of the system inserts in the instrument the setpoints associated with the well's flow rate. These setpoints determine for a given flow rate the on time for the chemical injection pump. Other chemicals can also be injected into the well using the system and the injection for those chemicals may be based on other criteria such as temperature, water rate, oil rate or pipeline flow rate.

  • Onboard controller for multistate windows
    Patent number: 9128346
    Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.
