Title: Method for separating and recycling waste polyester-cotton textile by means of hydrothermal reaction catalyzed by organic acid
Inventor: EDWIN YEE MAN KEH
IPC: C08L1/02
Filed: 2017-09-08
Abstract: A method for separating and recycling a waste polyester-cotton textile by means of a hydrothermal reaction catalyzed by an organic acid, comprising the following steps: cutting a waste polyester-cotton textile into fragments and dispersing in an aqueous solution system of an organic acid catalyst to obtain a mixed system; in a high-pressure reactor, heating the mixed system to 110-180°C so that cotton fibers in the waste polyester-cotton textile undergo a degradation reaction for 0.5-3 h to obtain a mixture; and filtering the mixture by means of a sieve, washing to obtain a polyester fiber aggregate, and then filtering the remaining portion by means of a filtration membrane in vacuum so as to obtain cotton fiber fragments after washing. The processing procedure of the method is advanced and simple, and the catalyst used during processing is derived from nature and is biodegradable, not decomposing during processing, and not polluting the environment; the present invention may effectively achieve the separation, recycling and reuse of waste polyester-cotton textiles.

Title: Torque request modification strategies for vehicles
Inventor: MATTHEW SULLIVAN
IPC: B60W20/17
Filed: 2020-04-21
Abstract: A system and method for controlling total driven wheel torque for a vehicle by controlling torque output of first and second torque sources providing drive torque to respective first and second axles (e.g. internal combustion engine 202, electric motor 212 in parallel through-the-road hybrid vehicle, re fig. 2). The method comprises receiving a requested total torque and hence producing first and second torque requests for the respective torque sources. When one or both torque requests is not satisfiable, a torque rate modifier adjusts one or both torque requests to approach or satisfy the requested total torque. The torque rate modifier increases or decreases the rate of change of torque request(s), which may allow deviation from required torque split ratio between the axles. The requests may be off-target due to torque shaping for lash zero crossing protection (LCP). Torque modification may be based on relative wheel torque response capabilities of the sources (e.g. faster torque response for motor than engine). If torques are changing in opposite directions, the higher rate may be decreased (e.g. see fig. 10). If only one torque is off-target and saturated, compensation torque may be provided from the other source. Torque may also be shaped for drivability.

Title: Strategic treatment of pressure ulcer using sub-epidermal moisture values
Inventor: MARTIN F BURNS
IPC: A61B5/0537
Filed: 2018-11-16
Abstract: Patient assessment and monitoring comprises an initial scan for sub epidermal moisture 644 (SEM) of a body location selected for monitoring. An initial delta value is calculated from that SEM scan. If that value exceeds a first threshold, there is possible damage at the body location. In that case, a second SEM scan of that body location is performed after a first time interval. All body locations get a SEM scan after a second, longer time interval. The patient is assigned to one of several risk categories, based partially on the initial SEM scan of the body location. In this way, SEM measurements may be limited to when they are needed. A delta value is calculated after each of the above SEM scans. Intervention may be recommended if a delta value exceeds a second threshold. Patient stratification may be partially based on risk assessment.

Title: Non-linear image contrast enhancement
Inventor: STEVE CARL JAMIESON PARKER
IPC: G06T5/40
Filed: 2022-05-30
Abstract: Disclosed is a method for enhancing the contrast in an image. The method starts by applying a gain to a received image by multiplying the pixel value of pixels in the image by a ratio of a target mean output pixel value and a mean pixel value for the pixel values of the pixels in the image 201. Then adjusting the distribution of pixel values of the gain-adjusted image by, determining a pixel difference value by calculating the difference between each gain-applied pixel value and the target mean output pixel value 202. Then determining an output image by mapping the pixel difference values into output image pixel values, using a mapping function that expands the distribution of pixel difference values close to the target mean output pixel value and compresses the distribution of pixel values far away from the target mean output pixel value 203. The method may calculate a histogram of the values of the pixels in the image, such that the mean value for pixel values is calculated using the histogram.
