Abstract: A compute-in-memory bitcell is provided that includes a pair of cross-coupled inverters for storing a stored bit. The compute-in-memory bitcell includes a logic gate formed by a pair of switches for multiplying the stored bit with an input vector bit. A controller controls the pair of switches responsive to a sign bit during a computation phase of operation and controls the pair of switches responsive to a magnitude bit during an execution phase of operation.

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: An acoustic tracking system is provided that includes a mobile device including a plurality of receivers that receives an acoustic signal from each of three transmitters disposed in a fixed, non-planar relationship with respect to each other, where the three transmitters are coupled to a transmitting device. The system also includes a processing component that determines based on the acoustic signals received at the plurality of receivers a position of the transmitting device in a multidimensional space. The system also includes an application controller that affects operation of an application based on a determined position of one or more transmitters of the three transmitters.

Abstract: A method includes receiving a first output from a first sensor of an electronic device and receiving a second output from a second sensor of the electronic device. The first sensor has a first sensor type and the second sensor has a second sensor type that is different from the first sensor type. The method also includes detecting a gesture based on the first output and the second output according to a complementary voting scheme that is at least partially based on gesture complexity.
