  • Publication number: 20250153619
    Abstract: The application relates to an invisible cover tie-down. A retainer is used to attach a trim cover to a seat cushion. The retainer has a weakened region between a region that attached to the trim cover and a region that extends into a slot in the seat cushion. The weakened region may be formed by reducing the thickness, such as by debossing (removing a layer of material), or by providing fewer layers. Alternatively or additionally, it may be formed by perforations along a fold line.

  • Patent number: 11565832
    Abstract: A harmless low-consumption on-orbit continuous launch system includes a satellite platform, a launch apparatus and a plurality of CubeSats. The satellite platform carries the launch apparatus and dozens or hundreds of CubeSats, and is launched from a ground into an orbit for on-orbit operation. The launch apparatus is configured to store the plurality of CubeSats and provide power for on-orbit launching of each of the CubeSats. A solid working medium in the launch apparatus is activated by heating to undergo a phase change, and the activated solid working medium expands instantly and is converted into a high-pressure gaseous working medium. The high-pressure gaseous working medium does work to eject the CubeSats, such that the CubeSats obtain a speed increment. The CubeSats enter a transfer orbit towards different target spacecraft through the speed increment applied by the launch apparatus to perform a plurality of different on-orbit serving missions.

  • Patent number: 9413370
    Abstract: An anti process variation self-adjustable on-chip oscillator has been disclosed according to the present invention. The on-chip oscillator includes the following components integrated on a same chip: a reference oscillation unit for producing reference pulse; an oscillation unit to be adjusted for producing output pulse; and a self-adjustable logic control unit for receiving the reference pulse and output pulse, and for transmitting a corresponding adjustment signal to the oscillation unit to be adjusted based on the received reference pulse and output pulse to control the oscillation unit to be adjusted to perform the frequency adjustment to the output pulse. The reference pulse required for adjusting the frequency can be generated by the reference oscillation unit integrated on-chip, so that self-adjustment can be achieved on-chip, decrease the cost of the chip compared with off-chip adjustment.
