Abstract: A mistranscription generated by a speech recognition system is identified. A received utterance is matched to a first utterance member within a set of known utterance members. The matching operation matches fewer than the first plural number of words in the received utterance and the received utterance varies in a first particular manner as compared to a first word in a first slot in the first utterance member. The received utterance is sent to a mistranscription analyzer component which increments evidence that the received utterance is evidence of a mistranscription. Once the incremented evidence for the mistranscription exceeds a threshold, future received utterances containing the mistranscription are treated as though the first word was recognized.

Abstract: An improved heat exchange apparatus is provided with an indirect evaporative heat exchange section consisting of a series of serpentine tubes which are kept uniformly spaced in the return bend section. Providing uniform return bend spacing on the return bend ends allow for ease of circuit assembly (stacking), ease of coil pull-down, ease of manufacturing, reduction in production cost, produces a higher quality hot dip galvanizing process and is a more robust design that tolerates manufacturing variability issues such as variable tube circuit length and variable return bend angles. Uniform return bend spacing also reduces scaling relative to prior art designs which had wet/dry areas resulting from shadowed tubes which were non-uniformly spaced, provides for better inspection and access to the tubes in the return bend area, maintains uniform air passage around tubes, promotes better tube wetting of the return bend area and ultimately promotes higher quality and higher performing heat exchanger coils.

Abstract: A method controls a robot. One or more processors receive sensor readings from one or more sensors that are monitoring a human in real time, where the human is currently observing a robotic action by a robot, and where the robotic action is a physical movement performed by the robot. The processor(s) determine a cognitive state of the human while the human is observing the robotic action by the robot, and then adjust the robotic action being performed by the robot based on the cognitive state of the human.
