Abstract: An intuitive interface may allow users of a computing device (e.g., children, etc.) to create imaginary three dimensional (3D) objects of any shape using body gestures performed by the users as a primary or only input. A user may make motions while in front of an imaging device that senses movement of the user. The interface may allow first-person and/or third person interaction during creation of objects, which may map a body of a user to a body of an object presented by a display. In an example process, the user may start by scanning an arbitrary body gesture into an initial shape of an object. Next, the user may perform various gestures using his body, which may result in various edits to the object. After the object is completed, the object may be animated, possibly based on movements of the user.

Abstract: A haptic system includes a haptic ring that is worn on the finger of a user. The haptic ring includes a flexible tube that is positioned against the finger pad of the user and configured to transport a fluid across the finger pad of the user. A first pump is configured to pump a warm fluid into the flexible tube and a second pump is configured to pump a cold fluid into the flexible tube, thereby providing a haptic sensation of temperature. A valve is positioned downstream of the haptic ring that is configured to open and close to modulate the pressure of the fluid, thereby providing a haptic sensation of pressure and/or vibration to the finger pad of the user. The haptic ring is unobtrusive and therefore does not significantly interfere with the ability of the user to perceive tactile sensations of the real world.

Abstract: A direct current (DC) removal circuit is coupled to a radio-frequency (RF) module, which includes a local oscillator. The DC removal circuit includes: a waveform generator, generating a digital waveform signal having an average value that is smaller than a resolution of a converter coupled to the RF module; a digital adder, coupled to the waveform generator, adding the digital waveform signal to a digital DC value to generate an addition result; and a digital subtractor, subtracting the addition result from a digital signal to generate a subtraction result, so as to compensate leakage caused by the local oscillator.

Abstract: A sampling phase difference compensation apparatus includes a signal generator, a signal analyzer and a compensator. The signal generator generates a first signal and a second signal, and outputs the first and second signals to a first path in a first time interval and a second path in a second time interval, respectively. The signal analyzer receives a transmitted first signal from the first path and a transmitted second signal from the second path, and performs a predetermined calculation on the transmitted first and second signals to determine a phase difference relationship, which is associated with a frequency-dependent phase difference and a sampling phase difference, between the transmitted first and second signals. The transmitted first signal is associated with the first signal, and the transmitted second signal is associated with the second signal. The compensator performs a phase difference compensation according to the phase difference relationship.

Abstract: A wireless signal receiver includes a receiving module, an automatic gain control (AGC) module, a measuring module, a decoding module, and a control module. The receiving module receives a wireless signal. The AGC module adjusts an amplitude of the wireless signal according to a gain to generate an adjusted signal. The measuring module measures a signal strength of the adjusted signal. The decoding module decodes the adjusted signal. When the decoding module determines that the adjusted signal corresponds to a beacon packet transmitted from a transmitting end, the control module adjusts the gain according to the signal strength.
