Abstract: Systems for efficiently starting an engine of a hybrid electric vehicle are provided. An example of a system comprises a first processor and a second processor. The second processor is configured to determine when to start an internal combustion engine, cause energy to be supplied from an energy storage device to a generator/motor to cause the generator/motor and crankshaft to rotate to at least a hold speed, transmit a first instruction to a first processor when determining that the internal combination engine should be started. The first processor does not supply fuel to at least one cylinder of the internal combustion engine in response to the first instruction. The second processor is configured to transmit a second instruction to the first processor after a variable period of time has elapse after the generator/motor or crankshaft has reached at least the hold speed.

Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR, over the Rayleigh fading channel. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Abstract: This disclosure is related to devices, systems, and techniques for controlling a temperature of water contained by a water tank. A controller includes a user interface configured to receive one or more user inputs indicative of a request to set a control parameter of the controller and communication circuitry configured to receive, from a user device, an electronic signal. Additionally, the controller includes processing circuitry configured to identify, from the electronic signal, one or more first data packets that include a request to disable an ability to change, based on the one or more user inputs received by the user interface, the control parameter of the controller and in response to receiving the one or more first data packets, disable the ability to change the control parameter of the controller.

Abstract: An HVAC controller is configured to automatically change between a HEAT mode and a COOL mode in accordance with a sensed temperature in the building structure, a HEAT temperature set point and a COOL temperature set point. The user is allowed to adjust the HEAT temperature set point and the COOL temperature set point, with the HVAC controller automatically adjusting one of the set points in response to the user making a change to the other of the other of the set points that violates a minimum deadband. If the user readjusts the user-adjusted set point in a way that no longer violates the minimum deadband, the HVAC controller will adjust the other set point back towards its previous setting.

Abstract: In some examples, a device can control one or more heating, ventilation, and air conditioning (HVAC) components within a building and control a digital user interface. The device includes a dial, the digital user interface, and processing circuitry. The processing circuitry is configured to scroll, in response to detecting a set of user inputs to one or both of the digital user interface and the dial, through a sequence of carousel screens for display on the digital user interface and display, on the digital user interface after a period of time following a most recent user input of the set of user inputs, a default carousel screen of the sequence of carousel screens. Additionally, the processing circuitry is configured to display, on the digital user interface, an idle screen corresponding to the default carousel screen of the sequence of carousel screens.

Abstract: A controller device for a heating, ventilation, and air conditioning (HVAC) system may output, while in a first state, a first user interface for display at a display device, where the first user interface includes first information at a first output size. The controller device may determine, while in the first state and based at least in part on whether an elapsed time since a most recent indication of user input received at a user input device exceeds a timeout period, that no users are physically proximate to the controller device. The controller device may, in response: transition the controller device from the first state to a second state and output a second user interface at the display device, where the second user interface comprises second information at a second output size that is larger than the first output size.
