Abstract: Methods and apparatuses are presented for controlling an application on a device. In some embodiments, a method may include detecting that a user is maintaining an object or gesture at a position hovering near the device for a threshold length of time. The method may also include anchoring an initial position of the object or gesture to the device based on the detection of the maintained position, and controlling the application using the anchored initial position. In some embodiments, controlling the application using the anchored initial position may include manipulating the application based on detecting within a stable zone associated with the anchored initial position a change in height of the gesture or object relative to the device, and not manipulating the application whenever the object or gesture is detected to move along a plane above and parallel to the device and within the stable zone.

Abstract: Methods and USB devices correlating clock domains are presented. A USB device includes at least one signal line adapted to carry signals in a first clock domain. The signals are received from a USB host. A clock operates a second clock domain. A periodic packet detection circuit detects a missing periodic packet from the signals received in the first clock domain. A device controller correlates a USB operation in the second clock domain with the first clock domain based on the periodic packet detection circuit detecting the missing periodic packet. A USB device includes at least one signal line carrying UTMI or ULPI signaling. A USB controller decodes packet identification from the UTMI or ULPI signaling. A periodic packet detection circuit, separate from the USB controller, decodes packet identification from the UTMI or ULPI signaling.

Abstract: Techniques are described for assisting near distance communications. A first device comprising a receiver, a sensor and a processor may be configured to perform the assisted near distance communication techniques. The receiver may receive, from a second device located within a conversational distance to the first device, monophonic audio data representative of the near distance communication. The sensor may generate a sensor signal representative of spatial information of the near distance communication. The processor may render, based on the spatial information and the monophonic audio data, multi-dimensional audio data in which the near distance communication originates in a soundfield from a location of the second device relative to the first device. The processor may next output the multi-dimensional audio data to a transducer so as to reproduce the near distance communication in multiple dimensions.
