Abstract: An access point (AP) and a station (STA) communicate with each other, with the AP indicating to the STA either or both of a preamble detection (PD) channel and a signaling (SIG) content channel and with the STA being initially monitoring a primary frequency segment of a plurality of frequency segments in an operating bandwidth of the AP. A downlink (DL) or triggered uplink (UL) communication is performed between the AP and the STA during a transmission opportunity (TXOP) such that: (i) during the TXOP, the STA monitors a preamble on the PD channel and decodes a SIG content on the SIG content channel; and (ii) after an end of the TXOP, the STA switches to the primary frequency segment.

Abstract: An arcuate display device includes a plurality of display units each having has a plurality of pixels, a virtual axis, and a plurality of driving devices. Each pixel includes first, second, and third light-emitting elements respectively disposed at first, second, and third positions. The driving devices corresponding to the display units having the same minimum distance from the virtual axis have the same circuit layout design. The first, second, and third positions are sequentially arranged in a direction away from the virtual axis. Optical properties of the first light-emitting elements and the third light-emitting elements in at least a part of the pixels disposed at a first side of the virtual axis are respectively substantially the same as optical properties of the third light-emitting elements and the first light-emitting elements in at least a part of the pixels disposed at a second side of the virtual axis.

Abstract: Embodiments of magnetic connectors are disclosed. Embodiments show the use of magnetic connectors for power and/or signal bus coupling to electronic devices from support bases, stands, or cables. In some embodiments, spherical contacts, such as ball bearings, are pressed into firm contact with an electronic device by the use of conductive springs, which in turn electrically couple the spherical contacts to the bus lines. Contact arrangements are shown which allow rotation of the electronic device against an embodiment of magnetic connector. Arrangements of multiple magnets having differing polarities are shown when alignment of an electronic device in a particular orientation is required.

Abstract: A pressure-sensitive stylus includes a tip operationally coupled to a pressure sensor, where the tip is constrained to depress longitudinally, and the tip is mechanically coupled to a first spring. The tip engages a second spring when depressed longitudinally by a force of a first magnitude.

Abstract: A communication system includes encoding and decoding devices. The encoding device includes an encrypting module adapted for encrypting an original signal into an encrypted signal, and an error correction encoding module coupled to the encrypting module for receiving the encrypted signal therefrom, and generating an output signal by performing error correction encoding on the encrypted signal. The decoding device includes an error correction decoding module for receiving an input signal via a transmission channel, and a decrypting module. The input signal is a result of the output signal combined with noise. The error correction decoding module generates a recovery signal from the input signal by performing error correction decoding on the input signal. The decrypting module is coupled to the error correction decoding module for receiving the recovery signal therefrom, and generates a decrypted signal that corresponds to the original signal by decrypting a portion of the recovery signal.
