  • Patent number: 10382669
    Abstract: A portable electronic device with image capturing capabilities automatically or semi-automatically adjusts one or more image capturing parameters based on an input attribute of user engagement with a single-action haptic input mechanism. For example, the duration for which a single-action control button carried on a frame of the device is pressed automatically determines an image stabilization mode for on-board processing of captured image data. In one example, an above-threshold press duration automatically activates a less rigorous image stabilization mode, while button release before expiry of the threshold automatically activates a more rigorous photo stabilization mode.

  • Publication number: 20190230635
    Abstract: The present invention is designed so that, when special subframes are allowed to transmit a PUSCH, the transmission of the PUSCH can be controlled adequately. According to the present invention, a user terminal has a receiving section that receives downlink control information (DCI) that schedules an uplink (UL) shared channel, and a control section that controls transmission of the UL shared channel by using a table that associates a subframe, in which the DCI is received, and a timing, at which the UL shared channel is transmitted, per UL/downlink (DL) configuration. The transmission timing in the table is determined based on a special subframe, which is allowed to transmit the UL shared channel, and a predetermined reference value, which is lower than 4 ms.

  • Publication number: 20190210564
    Abstract: Described are devices, systems and methods for real-time remote control of vehicles with high redundancy. In some embodiments, two copies of at least one control command are received using two different wireless communication protocols, and are compared. The at least one control command is executed when the two copies are in agreement, but is rejected when the two copies differ. In other embodiments, additional wireless communication protocols may exist to provide a redundant mode of communication when one of the two different wireless communication protocols are unavailable. In yet other embodiments, redundant GPS units may be used to determine availability of any of the communication protocols, and relevant control commands may be downloaded in advance to circumvent the lack of coverage.
