Embodiments of the invention comprise systems and methods for using the geographic location of networked consumer electronics devices as indications of occupancy of a structure for purposes of automatically adjusting the temperature setpoint on a thermostatic HVAC control. At least one thermostat is located inside a structure and is used to control an HVAC system in the structure. At least one mobile electronic device is used to indicate the state of occupancy of the structure. The state of occupancy is used to alter the setpoint on the thermostatic HVAC control to reduce unneeded conditioning of unoccupied spaces.

A controller unit for controlling the speed of a motor for driving an oil injected compressor, the controller unit including: a data connection; and a first module to receive data through the data connection. The controller unit includes a processing unit for determining a minimum working speed of the motor on the basis of the measured working pressure, the ambient temperature and a dew point temperature; and a comparator unit to compare the determined minimum working speed with the retrieved working speed of the motor. The processing unit includes a signal generating unit to send a signal to the motor for increasing the working speed of the motor to at least the determined minimum working speed, if the retrieved working speed is lower than the determined minimum working speed.

A system for an aircraft includes a first fluid circuit extending from a first end to a second end, and a network comprising a plurality of networked heater assemblies disposed along the first fluid circuit between the first end and the second end. Each of the networked heater assemblies includes at least one temperature sensor, a heater element, and a local controller. The at least one temperature sensor is in communication with the first fluid circuit for periodically measuring a temperature in the first fluid circuit and generating a corresponding local temperature signal. The heater assembly selectively applies heat to the first fluid circuit based on the local temperature signal or another temperature signal on the network. The local controller receives the local temperature signal or another networked temperature signal and operates the heater assembly in response thereto to maintain the local temperature signal above a predetermined threshold.

A heater control system is disclosed. In an embodiment, the heater control system includes a fluid heater that includes a heating element. The heating element controlled by a switch. The heater control system also includes a controller that can operate the switch. The controller is configured to determine whether a temperature associated with the fluid heater is below a predetermined temperature threshold. The controller causes the switch to transition to an operational state when the temperature is below the predetermined temperature threshold allowing current to flow through the at least one heating element.

A temperature control device comprises: an operation amount upper limit setting part that sets an upper limit of an operation amount of a heater; and a temperature change rate comparing part that determines, in every prescribed time period, whether an actual measured change rate of the temperature of a body-to-be-heated with respect to time is outside a prescribed range that includes a target rate of change. The operation amount upper limit setting part sets the upper limit to a preset initial value when operation of the heater is started toward the target temperature, and updates the upper limit, in a period until the temperature of the body-to-be-heated reaches the target temperature, such that the difference between an actual measured temperature and a temperature locus that is represented using the target rate of change becomes smaller when it is determined that the actual measured change rate is outside the prescribed range.

An increased efficiency boiler system includes a boiler, a thermostat in operative communication with the boiler and a controller. The controller is in communication with the boiler and the thermostat and selectively exchanges data with the boiler and the thermostat. The controller determines a proportional time period, reflecting how long the thermostat is requesting heat from the boiler within a predetermined time period, in dependence upon the exchange of data. The controller further determining a cycle frequency reflecting the number of times the thermostat is requesting heat from the boiler within the predetermined time period. The controller adjusts an energy input provided to the boiler in dependence upon the proportional time period and the cycle frequency.

A heat transfer system is arranged to cook multiple diverse food products. The heat transfer system includes at least one heat source. The at least one heat source is arranged within an enclosure and is operable by a controller to emit heat energy into the enclosure. First and second cooking conveyors are arranged within the enclosure. The first cooking conveyor is configured to move a first food product through the enclosure. The second cooking conveyor is configured to move a second food product through the enclosure. A speed of the first cooking conveyor and a speed of the second cooking conveyor are independently controlled to independently adjust the cooking time of the first food product and the second food product during operation of the heat transfer system.

Apparatuses, systems, and methods for brewing a desired portion of a beverage, such as a single-cup portion of coffee, are provided. The system can include one or more hopper assemblies configured to provide a controlled dose of beverage material to a brew chamber. The system can also include a water input system configured to wet the ground beverage material as the grinds enter the brew chamber and substantially prevent steam from reaching grinder components of the system. Further, the system can include an automatic cleaning mechanism such that a user does not need to manually clean components of a brewing machine between brew cycles.

A control device and methods for controlling an air conditioner are provided. The control device includes: an interface configured to receive measurement information indicating a detected indoor temperature; and a controller configured to, after initiating an air conditioning operation according to a set temperature which is inputted by a user, determine occurrence of an event according to a pre-defined criterion based on a relationship between the indoor temperature of the received measurement information and the set temperature with time, and, in response to the event occurring, change the set temperature.

Embodiments of the present invention relate to a method for controlling temperature of a terminal, including: receiving, by the terminal, an instruction for triggering execution of a first task; obtaining, by the terminal, a current temperature of the terminal; and controlling, by the terminal, an execution manner of the first task based on the current temperature, to control temperature of the terminal. When the terminal obtains the current temperature of the terminal, the terminal may control, based on the current temperature of the terminal, the first task to be executed in different manners, so as to control temperature of the terminal and ensure that the mobile phone is in a safe state.
