  • System and method for displaying visual notifications on an electronic device
    Patent number: 9599765
    Abstract: A light assembly for providing a notification light on an electronic device is described. The light assembly comprises a first light source for providing a background portion for the notification light, a second light source for providing a patterned portion for the notification light, and at least one pattern element to generate the pattern portion.
    Type: Grant

  • Contactless gesture recognition with sensor having asymmetric field of view
    Patent number: 9280283
    Abstract: Methods, devices and sensors for detecting a gesture are described. In an embodiment, a gesture sensor includes a time of flight sensor having a sensing element configured to generate an electrical signal responsive to received light. The time of flight sensor also includes a light source for emitting a burst of light. The sensing element has a sensing side for receiving light and a non-sensing side which is opposite the sensing side. The gesture sensor also includes one or more light inhibitors positioned relatively nearer the sensing side of the sensing element than the non-sensing side. The light inhibitors are asymmetric about a first center line of the sensing element. The first center line is located midway between first and second sides of the sensing element. The gesture sensor further includes a processor coupled to the time of flight sensor configured to detect a gesture.
