A method of providing performance reports to persons associated with the monitoring of an analyte level, such as blood glucose concentrations in a host, is provided. The performance reports can indicate a measure of an analyte variability of the host over a first analysis time period compared to a measure of analyte variability of the host over one or more other analysis time periods. The analyte level of the host can be received in each of a plurality of sensor readings from a continuous analyte sensor, such as multiple sensor readings per hour, so that the analyte variability that is used in determining the performance report of the host can be based on not just a few metered readings taken by the host, but a plurality of intermittent readings that are taken by a continuous analyte sensor, for example. Various types of performance reports can be generated, such as reports that comprise charts, graphs, tables, and/or other visual indicia of a host's performance during one analysis period versus another analysis period.

The present invention is related to the field of heating, ventilation and air conditioning (HVAC). More particularly, the present invention is related to methods and systems for controlled heating and cooling in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The present invention is directed to mathematical algorithms incorporated into a controller and a method of determining control signals that are dependent on said mathematical algorithms and user programming that integrates information from multiple sensors, thermostats as well as weather information. Used in any home or building, the controller controls heating, cooling and ventilation systems in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The controller works with typical HVAC systems generally in buildings and homes. The Smart-Stat algorithms are programmed into the controller and enable the controller to identify user-determined set-points alongside data from one or multiple internal temperature sensors. The user-determined set-points are also linked to time of day and day of week in a manner typical for typical thermostat devices available today. In such typical thermostat devices the controller will call for cooling or heating depending on the set points and conditions determined by the sensors in the building. The present invention is capable of interrupting the call for cooling or heating depending on whether the mathematical algorithms identify suitable outside weather conditions that permit the use of outside air cooling or outside air heating. Thus the call for heating or cooling can be redirected to call for ventilation instead of heating or cooling.

The invention comprises a method and apparatus for processing signals reflecting a physiological characteristic by performing an error minimizing mathematical combination between signals from at least two independent sensors. For example, the intensity of light is detected following tissue absorption at two wavelengths and the signals are corrected. Preferably, corrected intensity signals are derived by orthogonal regression. In one embodiment, the method and apparatus are used to determine arterial oxygen saturation.

In a device having a display, at least one sensor signal is generated from a sensor in the device. One or more context values are then generated from the sensor signal. The context values indicate how the device is situated relative to one or more objects. At least one of the context values is then used to control the operation of one or more aspects of the device.

Methods and apparatus for capturing or generating images using multiple optical chains operating in parallel are described. Pixel values captured by individual optical chains corresponding to the same scene area are combined to provide an image with at least some of the benefits which would have been provided by capturing an image of the scene using a larger lens than that of the individual lenses of the optical chain modules. By using multiple optical chains in parallel at least some benefits normally obtained from using a large lens can be obtained without the need for a large lens. Furthermore in at least some embodiments, a wide dynamic range can be supported through the use of multiple sensors with the overall supported dynamic range being potentially larger than that of the individual sensors. Some lens and/or optical chain configurations are designed for use in small handheld devices, e.g., cell phones.

A vigilance monitoring system to determine the alertness of a driver of a vehicle. The system uses one or multiple sensors located at the driver-vehicle interface (steering wheel, accelerator, brakes). The sensor monitors the magnitude and frequency of the force (or displacement) exerted by a driver at the driver interface. A time derivative of the force or displacement profile is created. The variability of the time derivative of the force/displacement data from the general trend of the data as obtained by an optimized moving average of the data. An intelligent control system measures the variability and compares with an alertness rating scale to determine the alertness score of the driver and issue warning signals and actions as appropriate.

Architecture for a multimodal, multiplatform switching, unmanned vehicle (UV) swarm system which can execute missions in diverse environments. The architecture includes onboard and ground processors to handle and integrate multiple sensor inputs generating a unique UV pilot experience for a remote drone pilot (RDP) via a virtual augmented reality cockpit (VARC). The RDP is monitored by an operational control system and an experienced control pilot. A ground processor handles real-time localization, forwarding of commands, generation and delivery of augmented content to users, along with safety features and overrides. The UVs onboard processors and autopilot execute the commands and provide a redundant source of safety features and override in the case of loss of signal. The UVs perform customizable missions, with adjustable rules for differing skill levels. RDPs experience real-time virtual piloting of the UV with augmented interactive and actionable visual and audio content delivered to them via VARC systems.

An electrical network architecture including a reconfigurable interface layer, along with a corresponding reconfiguration methodology. The interface layer is comprised of reconfigurable interface devices which allow a plurality of sensors and actuators to communicate with a plurality of control units. Each sensor or actuator is connected to multiple interface devices, which in turn are connected to a bus. The control units are also connected to the bus. In the event of an interface device failure, other interface devices can be reconfigured to maintain communication between sensors, actuators and control units. In the event of a control unit failure, the interface devices can be reconfigured to route sensor and actuator message traffic to a different control unit which can handle the functions of the failed control unit. The overall number of control units can also be reduced, as each control unit has flexible access to many sensors and actuators.

A time of day zoning control system for a heating, ventilating, and air conditioning system is provided. The system utilizes a programmable thermostat and a number of temperature sensors to control the HVAC system to regulate the temperature in a particular location within a dwelling or structure based on consumer preferences. The regulation control will utilize a temperature sensed by a particular temperature sensor at different times throughout the day to control the temperature in that zone to ensure occupant comfort. A single temperature sensor may be selected to control the HVAC system during these different periods, or multiple sensors may be utilized during the same period. When multiple sensors are used, a weighting factor may be used.
