  • Patent number: 10379560
    Abstract: Techniques are provided for power optimization of home automation system devices (e.g., battery-powered devices). In one example embodiment, the power optimization is based on service states for a room associated with the device. A service state is determined for each of one or more services available in the room. The device is maintained in a low-power inactive state while there are no active services in the room. In response to at least one service being activated, the device transitions from the inactive state to a full-power in-use state. Such transition is performed preemptively, absent any current attempt to use the device by a user or another device. In response to expiration of a timer since a last use of the device or the transition to the in-use state was made and no actual use occurred, the device exits the in-use state and may eventually return to the inactive state.

  • Patent number: 10342381
    Abstract: Automatic coffee machines have very low thermal efficiency because they have to heat a considerable thermal mass, constituted by the heater 3) appearing in FIG. 1, which has a weight generally ranging between 0.5 and 1 Kg of metal, typically consisting of aluminum. Said mass is used to stabilize the temperature of the water to be injected in the blend of coffee. In this configuration, 90% or more of the thermal energy is wasted. The energy saving coffee machine, the subject matter of the present invention, is instead constructed with a heater 3), appearing in FIG. 4, that has a thermal mass much lower than the mass of the liquid to be heated, and is typically constructed with metal tube 30), as shown in FIG. 4, weighing a few grams. The heating current 41) in FIG. 4 flows directly on said tube, heating it together with the water contained therein, while a very rapid temperature control circuit makes it possible to maintain a constant temperature of the water flowing through the heater 3) shown in FIG. 4.

  • Patent number: 10288001
    Abstract: The control system of an internal combustion engine controls an internal combustion engine comprising an exhaust sensor. The control system comprises a motoring device driving rotation of a crankshaft of the internal combustion engine, a motoring control part configured to control the motoring device, a heater control part configured to control supply of electric power to the heater, and a temperature estimating part configured to estimate a temperature of the sensor element. The motoring control part is configured to drive the motoring device for a predetermined time when the temperature of the sensor element estimated by the temperature estimating part is outside a predetermined cracked element temperature region while the heater control part is supplying electric power to the heater, and stop driving the motoring device when the temperature of the sensor element is within the cracked element temperature region.

  • Patent number: 10180098
    Abstract: A control device of an exhaust sensor comprises a battery voltage detection part detecting a voltage of a battery, and a heater control part setting a target temperature of an electrochemical cell and controlling the electric power supplied from the battery to a heater. The heater control part sets the target temperature to a first temperature after startup of the internal combustion engine until the voltage of the battery recovers to a predetermined voltage, and switches the target temperature from the first temperature to a second temperature when the voltage of the battery recovers to the predetermined voltage. The first temperature is a temperature lower than an operating temperature of the electrochemical cell and at least a lowest temperature at which a Leidenfrost phenomenon occurs at the protective layer. The second temperature is a temperature of the operating temperature or more.

  • Patent number: 10173579
    Abstract: In certain example embodiments, moisture sensors, defoggers, etc., and/or related methods, are provided. More particularly, certain example embodiments relate to moisture sensors and/or defoggers that may be used in various applications such as, for example, refrigerator/freezer merchandisers, vehicle windows, building windows, etc. When condensation or moisture is detected, an appropriate action may be taken (e.g., actuating windshield wipers, turning on a defroster, triggering the heating of a merchandiser door or window, etc.). Bayesian approaches optionally may be implemented in certain example embodiments in an attempt to improve moisture detection accuracy. For instance, models of various types of disturbances may be developed and, based on live data and a priori information known about the model, a probability of the model being accurate is calculated. If a threshold value is met, the model may be considered a match and, optionally, a corresponding appropriate action may be taken.
