摘要:
A method and apparatus for governing sensor data readings from a plurality of input sensors onboard a communications device. An inventory of available input sensors is generated, and a set of requested input sensors from an application running on the communications device is received. The requested input sensors that are absent from the inventory of available input sensors is identified, and based upon received measured values from the available input sensors, equivalent values for those absent input sensors are derived. The accuracy and precision of the measured and equivalent sensor values are estimated, and those measurements not meeting certain thresholds are filtered. The measured values and the derived equivalent values meeting the predetermined thresholds for accuracy and precision, and the filtered measured values and the filtered derived equivalent values are output to the application.

A circulating bath (10) including a heater (18) configured to heat a fluid (34) in a reservoir (22). The heater (18) is configured to be operatively connected to a source of power (50) by a control circuit (39) operatively coupled to the heater (18). First and second fluid level sensors (14) (16) are operatively coupled to the control circuit (39), and provide signals indicative of a low fluid condition in the reservoir (22). The control circuit (39) is configured to receive the signals from the fluid level sensors (14) (16), and disconnect the heater (18) from the source of power (50) in response to receiving a signal from either of the first and second fluid level sensors (14), (16) indicative of a low fluid condition.

Devices and methods for warming or cooling blood flowing through the vasculature of a human or animal subject so as to alter or control the temperature of all or part of the subject's body. Heat exchangers are positioned within the subject's vasculature and heated or cooled heat exchange fluid is circulated through the heat exchanger. For certain therapeutic applications, the heat exchanger and associated elements of the system have sufficient power to lower the subject's body temperature by at least 3 degrees C in less than 30 minutes.

A turbo-generator system generates electricity from the exhaust gas of an internal combustion engine 1. The electric current generated by the generator 11 (e.g. a switched reluctance machine) is controlled so as to maintain the turbine 3 at a first pre-set rotational speed. The amount of electric current demanded from the generator 11 is limited or reduced if the electrical system 17 cannot accept a greater electric current or if the exhaust gas pressure upstream of the turbine 3 is too great. In such cases, the proportion of the exhaust gas permitted to bypass the turbine 3 is controlled so as to maintain the turbine 3 at a second pre-set rotational speed that is slightly greater than the first. The turbine's preset speeds are chosen to maximise electrical generating efficiency and for turbine safety. The system maximises the amount of electricity generated, avoids excessive exhaust gas back-pressure on the engine 1, and avoids overloading the electrical system 17.

A method includes: generating a trellis; generating one or more predicted symbols using a first non-linear model; computing and saving two or more branch metrics using a priori log-likelihood ratio (LLR) information, a channel observation, and the one or more predicted symbols; if alpha forward recursion has not yet completed, generating alpha forward recursion state metrics using a second non¬ linear model; if beta backward recursion has not yet completed, generating beta backward recursion state metrics using a third non-linear model; if sigma forward recursion has not yet completed, generating sigma forward recursion state metrics using the branch metrics, the alpha state metrics, and the beta backward recursion state metrics; generating extrinsic information comprising a difference of a posteriori LLR information and the a priori LLR information; computing and feeding back the a priori LLR information; and calculating the a posteriori LLR information.

A method for determining an output signal is provided. A radio device identifier associated with a second radio device is stored in a first radio device. One or more configuration parameter settings associated with the second radio device are stored in the first radio device. The first radio device identifies the second radio device based on the radio device identifier. In response to identifying the second radio device, the first radio device automatically determines the configuration parameter settings should be used to determine an output signal based on a user input. The first radio device establishes a radio communications link with the second radio device. The first radio device receives the user input. Based on the configuration parameter settings and the user input, the first radio device determines the output signal. The first radio device transmits the output signal to the second radio device through the radio communications link.

A spoiler assembly is provided that is engageable to a UAV that defines a body, an outer surface and an inner surface. The spoiler assembly comprises a spoiler, translatably connected to the UAV inner surface adjacent a first portion of the spoiler aperture. The spoiler defines an upper surface and an outer surface, the upper surface being substantially the same size and shape as the spoiler aperture. A spoiler shroud is connected to the UAV inner surface and extends within the UAV body about at least a portion of the spoiler aperture. A spoiler activating mechanism is secured to the UAV inner surface and connected the spoiler lower surface. The mechanism is operative to translate the spoiler between a first position wherein the spoiler upper surface is substantially flush with the UAV outer surface, and second a position, wherein the spoiler upper surface is disposed substantially within the UAV body.

Electronic light emitting flares and related methods. Flares of the present invention include various features such as self-synchronization, remote control, motion-actuated or percussion-actuated features, dynamic shifting between side-emitting and top-emitting light emitters in response to changes in positional orientation (e.g., vertical vs. horizontal) of the flare; overrides to cause continued emission from side-emitting or top-emitting light emitters irrespective of changes in the flare's positional orientation; use of the flare(s) for illumination of traffic cones and other hazard marking or traffic safety objects or devices, group on/off features, frequency specificity to facilitate use of separate groups of flares in proximity to one another, selection and changing of flashing patterns and others.
