Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.

Abstract: This disclosure describes systems, methods, and devices related to multiple-input multiple-output (MIMO) channel access. A device may determine one or more time division duplex (TDD) service periods (SPs). The device may determine a directional multi-gigabit (DMG) frame to be sent to a responder device on a channel associated with a MIMO communication. The device may cause to send the DMG frame to the responder device on the channel. The device may establish a MIMO channel access based on sending the DMG frame to the responder device.

Abstract: Devices and methods related to high-contrast liquid crystal displays (LCDs) are provided. For example, such an electronic device may include an LCD with two liquid crystal alignment layers not symmetric to one another and upper and lower polarizing layers respectively above and below the alignment layers. Light transmittance through the plurality of pixels may increase monotonically with gray scale voltage. The display may operate using a gray scale level 0 voltage higher than a minimum gray scale level 0 voltage capability of the display. Additionally or alternatively, liquid crystal molecular alignment axes of the two alignment layers may be offset from one another by an angle other than a multiple of 180 degrees. Additionally or alternatively, a first polarizing axis of the upper polarizing layer or a second polarizing axis of the lower polarizing layer, or both, may be neither parallel nor perpendicular to one of the liquid crystal molecular alignment axes.

Abstract: A meat grinder has a motor assembly and a grinding assembly. The motor assembly has a motor. The motor has an output axle having an annular abutting surface. The grinding assembly is securely connected with the motor assembly and has a grinding tube, a threaded rod, a blade, and an extrusion panel. The grinding tube is connected to the casing of the motor assembly and has an annular connecting base. The threaded rod is rotatably mounted in the grinding tube and has a connection segment. The connection segment is mounted through the connecting base, is connected with the output axle of the motor, and is stepped in section to form an annular abutting shoulder. The abutting shoulder is formed around the connecting segment and abuts the annular abutting surface of the output axle.

Abstract: A braiding apparatus includes a base, a strand supplier supplying a core strand, strand carriers shuttling on the base and providing carrier strands that wrap the core strand and twist together to form a rope, a guiding pulley disposed above the strand carriers to feed the rope to a strand collector, and a control device having a driving source connected to the guiding pulley, at least one recognition unit arranged on the guiding pulley, a sensor disposed relative to the guiding pulley, and a controller electrically connected to the sensor and the driving source. The sensor counts the number of the recognition unit passing the sensor when the guiding pulley rotates to measure lengths of divided sections of the rope. Concurrently, the controller controls the driving source and the guiding pulley to have different rotational speeds, thereby controlling different braid densities of different sections of the same rope precisely.
