Abstract: An apparatus can include an apparatus housing, a substantially planar touch surface coupled to the apparatus housing, and a plurality of oblique sensors coupled to the touch surface. Each oblique sensor of the plurality of oblique sensors can have a sensor surface substantially oblique to the touch surface. The plurality of oblique sensors can detect a touch force parallel to the touch surface.

Abstract: Embodiments include antenna tuning systems and methods of tuning an antenna of a wireless device with an antenna, a circuit with at least one tunable component, and a processing system. The processing system determines tuning selection inputs during a communication session. Based on the tuning selection inputs, the processing system determines one or more component values for one or more tunable components. In an embodiment, the component value(s) are determined from a set of pre-defined component values. The tunable component(s) are controlled to have the determined component value(s). The circuit may be an impedance matching circuit that includes at least one tunable reactive component. Alternatively, the circuit may be an antenna tuning circuit that includes at least one variable component. In an embodiment, both an impedance matching circuit and an antenna tuning circuit may be implemented, with each type of circuit having one or more tunable components.

Abstract: A multimode communication device (10 or 50) having an antenna arrangement (14 or 54) having a first antenna (18) operational in both low bands and high bands, a second antenna (20) operational in high bands, a tuner (26) coupled to the first antenna adapted to adjust matching elements to modify return loss to lower reflected power, a switching mechanism (28) for selecting between the first antenna and the second antenna, and a controller (30) coupled to the switching mechanism and the tuner.

Abstract: An apparatus for radio frequency testing of a wireless communication device (205) comprising an artificial head (100) and a spacer (203). The artificial head (100) includes a mouth (103) and an ear (105, 107), and the spacer (203) is positioned adjacent to the artificial head (100). The spacer (203) positions an audio output portion of the wireless communication device (205) adjacent to the ear (105, 107) of the artificial head (100), directs an audio input portion of the wireless communication device (205) toward the mouth (103) of the artificial head (100), and separates the audio input portion of the wireless communication device (205) from the mouth (103) of the artificial head (100).

Abstract: A model hand (120, 700) for use in electromagnetic testing comprising a body (210, 710) and at least one digit (220, 780) extending from a side of the body. For one embodiment, the body (210) has an outer semi-cylinder surface (230) with an arcuate shape and an inner semi-cylinder surface (240) following the arcuate shape of the outer semi-cylinder surface. A digit (220) is coupled at a base end (260) coupled to the side (250) of the cylindrical body (210) to permit pivotal motion of the digit relative to the cylindrical body. For another embodiment, the body (710) has a palm-like shape with four static digits (740-770) affixed at one end to the palm-shaped body. In addition to the four static digits (740-770), a dynamic digit (780) extends from the body (710) and couples to the body to permit pivotal motion of the digit relative to the body.
