Abstract: Embodiments are directed to collections of flooring tiles, such as carpet tiles, that can include (1) a first group of tiles that has a first uniform appearance, visual field, and/or pattern across the entire tile, (2) a second group of tiles that has a second uniform appearance, visual field and/or pattern across the entire tile, and (3) a third group of tiles that are divided into three portions: a first portion that bears the first visual field, a second portion that bears the second visual field, and a third portion generally interposed between the first portion and the second portion and that has an appearance different from both the first and the second visual field. Tiles from the collections can be installed to create a desired appearance on a floor.

Abstract: Methods of cutting a flooring web into rectangular flooring tiles such that at least one vertical cut along the length of the web defines a shorter edge of the rectangular tiles and horizontal cuts across the width of the web define the longer edges of the rectangular tiles.

Abstract: The present invention relates to a method for grafting a surface of a medical device by using quaternized trimethylamine. A catheter onto which quaternized trimethylamine has been grafted allows for the reduction of thrombus production. Therefore, the catheter having quaternized trimethylamine grafted thereto exhibits the effect of repressing thrombus production and enhancing the function of inhibiting blood adsorption and blood cell adsorption.

Abstract: Floor coverings, such as modular panels or tiles, for installation on interior surfaces include one or more layers, for example, an upper wear layer and a backing layer, where at least one layer includes a filler that includes a carbon negative material, such as concentrated carbon. The carbon negative material can sequester carbon such that the resulting floor covering has a negative carbon footprint when subjected to a Life Cycle Assessment.

Abstract: Certain aspects and features relate to using an image modifier to generate digital designs and to printing the digital designs on a structure for flooring or other decoration that can more realistically mimic designs found in nature or otherwise provide designers with the freedom to create aesthetic designs more easily. An image modifier can receive an image, such as an image of a naturally occurring view and generate modified designs based on the image. The modified designs can be slight modifications to the image and printed on the structures for flooring such that together the printed structures exhibit the appearance of a design found in nature or a desired appearance by a designer.

Abstract: A wireless load cell monitoring system and method may comprise a remote load cell assembly and a base station. Embodiments of the remote load cell assembly comprise a remote processor, a remote memory, a battery, a remote transceiver, an analog-to-digital converter, and a load cell. Embodiments of the base station comprise a base processor, a base memory, a base transceiver, and a digital-to-analog converter. Embodiments of the remote load cell assembly pair with the base station using a wireless communication protocol, read analog voltage data from the load cell, convert the load cell analog voltage data into digital load data, and transmit the digital load data to the base station. Embodiments of the base station convert the digital load data into analog voltage data and output the analog voltage data.

Abstract: A system and method configured to measure applied force and pressure on a load cell. The system includes an axial force pressure transducer having a hollow cross section comprising at least two strain sensitive regions, and a plurality of strain sensors connected to the at least two strain sensitive regions, wherein applied force and pressure is calculated based on strain measurements using mathematical formulae. A method of calibration of the axial force pressure transducer using known applied force and pressure measurements to calculate a calibration matrix reflecting the strain sensitivities of the at least two strain sensitive regions.

Abstract: Tools are provided that communicate to a pattern designer how much yarn is being used on every needle for a given tuft height pattern and permit the designer to adjust the pattern accordingly to balance the yarn usage on the needles. An electronic representation of a pattern design is received for controlling a carpet tufting operation. The pattern design includes a pile height per tuft. A grid is provided for representing the pattern design using different visual cues to represent different pile heights. A graph depicting use-of-yarn per needle for the carpet tufting operation is generated. The grid and the graph can be on a common user interface and can be viewable at the same time on a display device.

Abstract: A floor covering system can include sensors below a top surface of a floor covering and that can communicate data to a controller for monitoring events occurring in the room with the floor covering. The sensors can include a wireless transmitter associated with a tile connector, a pressure sensor, and a force sensor. The tile connector is positioned between a floor and a floor covering to connect tiles of the floor covering together. The pressure sensor is positioned between the floor and the floor covering. The force sensor is positioned between the floor and the floor covering. The controller is configured for receiving data from the pressure sensor, the wireless transmitter, and the force sensor.

Abstract: Design and manufacture of tufted articles, carpet tile webs and carpet tiles, and installation of carpet tiles, having different color, pile height, pile texture or other characteristics that, together with similar other such tiles, may be installed to create borders, edges or other multiple-tile designs, usually without any of the tiles looking out of place or improperly oriented relative to nap or the direction the tile is “facing.
