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.

Abstract: A test device includes a power compensation module and a test module. The power compensation module receives AC power generated by a device under test to generate DC power to the device under test. The test module provides a plurality of test signals and a test mode to the device under test for testing the device under test.

Abstract: A motorized window treatment may include a roller tube, a flexible material attached to the roller tube, a motor drive unit, and mounting brackets configured to rotatably support respective ends of the roller tube. The roller tube may be operable between an operating position and an extended position. The extended position may include one or more ends of the roller tube being accessible while still attached to the mounting brackets. At least one of the mounting brackets may include a stationary portion, a sliding portion, and/or a translating portion. The translating portion and/or the sliding portion may be configured to translate the roller tube between the operating position and the extended position. The translating portion may define an attachment member and include an attachment aperture. The end of the roller tube may be accessible via the attachment aperture when the roller tube is in the extended position.

Abstract: A designing method of a gear skiving cutter that includes: constructing a cutter manufacturing tool with a plurality of asymmetrical tooth structures and a base material for the gear skiving cutter; simulating relative movements of the cutter manufacturing tool and the base material based on multi-axes in a relative motion coordinate system to have the cutter manufacturing tool process the surface of the base material; and forming a plurality of cut teeth on the base material by the plurality of tooth structures of the cutter manufacturing tool. An outer contour of each cut tooth is designed in advance so that gear teeth on a gear workpiece with a planned grinding allowance can be formed when the gear workpiece is processed by the gear skiving cutter. The grinding allowance on either side of each gear tooth can be kept uniform, and the grinding allowance on both sides of each gear tooth can be closely the same.

Abstract: A multicomponent alloy coating is provided. The multicomponent alloy coating includes a hard layer and a plurality of nickel-based particles dispersed in the hard layer. The composition of the multicomponent alloy coating is represented by the following formula (I): AldCoeCrgFehNiiSijCkOm??formula (I), wherein 1<d<2, 0.5<e<0.8, 2<g<3.2, 0.05<h<0.3, 2<i<3, j=1, k?0, m?0, and iron is present in the amount of less than 3 wt % of the composition of the multicomponent alloy coating.

Abstract: The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

Abstract: An example adapter device includes a host-side connector to connect to a host device, the host-side connector including a host-side electrical contact to connect to a corresponding electrical contact of the host device. The adapter device further includes a storage-side connector to connect to storage devices operable under different protocols, the storage-side connector including a storage-side electrical contact to connect to a connected storage device. The adapter device further includes a circuit to apply a bias voltage to the host-side electrical contact. The host-side electrical contact is to provide a protocol-indicating voltage to indicate to the host device a protocol of the connected storage device. The protocol-indicating voltage is dependent on the connected storage device's influence on the bias voltage.
