摘要： An assistive device and method for non-visually discerning a three-dimensional (3D) real-world area surrounding a user, comprises a haptic feedback interface that includes a plurality of haptic elements. The assistive device receives sensor data of the 3D real-world area within a first proximity range of the assistive device from a plurality of different types of sensors that are communicatively coupled to the assistive device. The assistive device establishes a mapping of a plurality of objects within the first proximity range to the plurality of haptic elements in a defined region of the haptic feedback interface, based on the received sensor data. A haptic feedback generator generates a touch-discernible feedback on the haptic feedback interface based on the established mapping. The touch-discernible feedback comprises a plurality of differential touch-discernible cues to enable the user to non-visually discern the 3D real-world area surrounding the user.

摘要： Methods and systems for dynamically tuning and calibrating an antenna using on-chip digitally controlled array of capacitors are disclosed. Aspects of one method may include dynamically tuning a mobile terminal antenna (MTA) using on-chip arrays of capacitive devices. The tuning may be, for example, to compensate for center frequency drift during operation of the mobile terminal. The tuning may be accomplished by selecting capacitive devices in the on-chip arrays of capacitive devices to use in conjunction with an inductive circuit coupled to the MTA, where the inductive circuit may be either off the chip or on the chip. Accordingly, an impedance of the circuit formed by the capacitive devices in the on-chip arrays of capacitive devices and the inductive circuit may be adjusted with respect to the MTA. A valid circuit configuration may include a configuration where no capacitive device may be selected for use with the inductive circuit.
