Abstract: Described herein is a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material including the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer, intermediate spacer yarns, and a lower surface layer, and the upper surface and the lower surface layer are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.

Abstract: Systems, methods and instrumentalities are described herein for automating a medical environment. The automation may be realized using one or more sensing devices and at least one processing device. The sensing devices may be configured to capture images of the medical environment and provide the images to the processing device. The processing device may determine characteristics of the medical environment based on the images and automate one or more aspects of the operations in the medical environment. These characteristics may include, e.g., people and/or objects present in the images and respective locations of the people and/or objects in the medical environment. The operations that may be automated may include, e.g., maneuvering and/or positioning a medical device based on the location of a patient, determining and/or adjusting the parameters of a medical device, managing a workflow, providing instructions and/or alerts to a patient or a physician, etc.

The front side metal layer has first and second front side power rails. The back side metal layer has first and second back side power rails. The first FTV extends through the substrate, and couples the first front side power rail to the first back side power rail. The second FTV extends through the substrate, and couples the second front side power rail to the second back side power rail. The power control circuit is coupled to the first and second front side power rails, and is controllable to electrically connect the first front side power rail to the second front side power rail, or electrically disconnect the first front side power rail from the second front side power rail.

Abstract: This application provides network device capacity expansion methods and devices. One method includes: obtaining network performance data of a target network device, determining a state of the target network device based on the network performance data of the target network device, and determining, based on the state of the target network device, whether to perform capacity expansion for the target network device. In the foregoing technical solution, whether a capacity expansion operation needs to be performed on a network device can be determined in a timely manner based on a state of the network device.

Abstract: Described herein is a polyurethane foam produced in a “one shot process” that has low density, is semi-hard, and displays a high rebound value all while providing superior split tear performance. The polyurethane foam can be used in a “one shot process” to produce a shoe sole, a mid-sole or an insole for a shoe. The shoe sole may be used for forming an outer sole of a sandal type shoe, a midsole of an athletic type shoe, or an insole for insertion into any type of shoe.

Abstract: Described herein is a composition which can produce elastomeric microcellular foam having improved and well-balanced mechanical properties, including a polyisocyanate, a polyol, a lactam, a surfactant and a blowing agent. Also described herein is a process to produce elastomeric microcellular polyurethane foam, and the use of the elastomeric microcellular polyurethane foam in footwear foam.

Abstract: Embodiments of the present invention provide a delay measurement method and device. The method includes: determining a first delay of a first path; obtaining a first two-way delay of a first two-way path; obtaining a first one-way delay from a third IGW port to a provider/provider edge device; obtaining a second one-way delay from the provider/provider edge device to a first IGW port; determining a second delay, where the second delay is obtained by subtracting the first one-way delay and the second one-way delay from the first two-way delay; and comparing the first delay with the second delay. By means of the foregoing solutions, a one-way delay relationship between delays from the OTT server to different IGWs may be effectively determined, so as to determine a path whose one-way delay is optimal according to the one-way delay relationship.
