  • Publication number: 20240095984
    Abstract: Some examples of the disclosure are directed to systems and methods for presenting content in a three-dimensional environment by one or more electronic devices in a multi-user communication session. In some examples, a first electronic device and a second electronic device are communicatively linked in a multi-user communication session, wherein the first electronic device and the second electronic device are configured to display a three-dimensional environment, respectively. In some examples, the first electronic device and the second electronic device are grouped in a first spatial group within the multi-user communication session. In some examples, if the second electronic device determines that the first electronic device changes states (and/or vice versa), the user of the first electronic device and the user of the second electronic device are no longer grouped into the same spatial group within the multi-user communication session.

  • Patent number: 8857259
    Abstract: A reading circuit of a gyroscope is provided. The reading circuit includes a driving unit, a high pass filter, a signal processing unit, and a low pass filter. The driving unit generates a resonance signal for a resonator of the gyroscope and generates a demodulation signal for the signal processing unit. The signal processing unit provides a modulation signal to a Coriolis accelerometer of the gyroscope. An input terminal of the high pass filter receives an output signal of the Coriolis accelerometer. The signal processing unit processes and demodulates an output of the high pass filter according to the demodulation signal and outputs a demodulation result to the low pass filter.

  • Publication number: 20130130868
    Abstract: A hardness adjustable platform for supporting a conveyor belt of a treadmill includes a platform body having internal spaces, and a plurality of elastic fillers moveably and respectively disposed in the internal spaces of the platform body for providing a cushion effect. The fillers are moveable relative to the platform body by an external force and divide the platform body into first and second regions having different hardness. As a result, the runner who uses the treadmill equipped with the aforesaid platform may adjust the positions of the fillers according to his/her physical condition and running speed to change the hardness distribution of the platform so as to enhance his/her running efficiency and reduce the risk of exercise injury.
