摘要:
The present invention discloses a polymer blend of sulfonated polymer such as poly(ether ether ketone) and poly(amide imide) for use as an proton-conducting membrane. The poly(amide imide) is prepared by conducing a ring-opening and condensation reactions of diisocyanate and 1,2,4-benzenetricarboxylic anhydride (TMA). The polymer blend has a reduced methanol uptake and methanol permeability while maintaining good proton conductivity, and thus is suitable for use as a proton-conducting membrane of a fuel cell. The present invention also discloses a process for preparing the poly(amide imide).
摘要:
Systems, apparatuses, and/or methods to characterize a user feature. For example, and apparatus may include a pattern receiver to receive a feature infrared (IR) pattern corresponding to non-uniform IR radiation reflected by skin of the user feature and an object IR pattern corresponding to IR radiation reflected by an object. The apparatus may further include a filter to generate a modified IR pattern from the object IR pattern and to remove at least a part of the modified IR pattern from feature IR pattern. In addition, the apparatus may include a feature characterizer to characterize the user feature based on the feature IR pattern. In one example, a computing platform may be controlled based on the characterization of the user feature.
摘要:
A washable, wearable biosensor that can gather sensor data, communicate the sensed data by wireless protocols, and permits the analysis of sensed data in real-time as a person goes about their normal lifestyle activities. The biosensor can be worn in multiple positions, can be put on or removed quickly without having to apply or remove gels and adhesives, and provides a snug, comfortable fit to gather data with minimal motion artifacts. The textile, wearable device can support integrated photoplethysmography, skin conductance, motion, and temperature sensors in a small wearable package. The supported sensors may be coupled to utilization devices by channel-sharing wireless protocols to enable the transmission of data from multiple users and multiple sensors (e.g. both sides of body, wrists or hands and feet, or multiple people). An on-board processor, or the receiving utilization device, can map patterns of the physiological and motion data to signals or alerts such as a likely seizure, drug craving, or other states that the wearer may exhibit or experience. The sensor data may be sent by wireless transmission and received by a mobile phone or other personal digital device, a computer, a favorite toy, or another wearable device. The sensors may include multiple photoplethysmographs and/or one or more EDAs which perform a time-domain measurement of skin conductance.
