    Abstract: A UE side Broadcast/Multicast Control (BMC) protocol layer determines those Cell Broadcast Service (CBS) messages (and their repetitions) which the UE shall read or ignore in a succeeding CBS schedule period, based on the CBS Schedule Message contents (Message Description Type and New Message Bitmap) received in a current CBS schedule period, the CBS messages already stored in the BMC, and the CBS messages to be received. In this manner, the UE may ignore CBS messages it has already received, without knowledge of the CBS message serial numbers, and thus conserve resources such as battery power.

    Abstract: A multi-mode, dynamic, DC-DC converter supplies a dynamically varying voltage, as required, from a battery to an RF power amplifier (PA). In envelope tracking mode, a fast DC-DC converter generates a dynamic voltage that varies based on the amplitude envelope of an RF signal, and regulates the voltage at the PA. A slow DC-DC converter generates a steady voltage and regulates the voltage across a link capacitor. The fast and slow converters are in parallel from the view of the PA, and the link capacitor is between the fast converter and the PA. Because different nodes are regulated, no current sharing is possible between the converters. The link capacitor boosts the dynamic voltage level, allowing a maximum dynamic voltage at the load to exceed the battery voltage. In power level tracking mode, the fast converter is disabled and the link capacitor is configured to be in parallel with the load. The slow converter directly regulates the PA, and the link capacitor is in parallel with (added to) an output capacitor. Multiple wireless network standards may be supported, allowing for the sharing of RF circuits.

    Abstract: A method is disclosed of indicating a suitable pose for a camera for obtaining a stereoscopic image, with the camera comprising an imaging sensor. The method comprises obtaining and storing a first image of a scene using the imaging sensor when the camera is in a first pose; moving the camera to a second pose; and obtaining a second image of the scene when the camera is in the second pose. One or more disparity vectors are determined, each disparity vector being determined between a feature identified within the first image and a corresponding feature identified in the second image. On the basis of the one or more disparity vectors, a determination is made of whether the second image of the scene is suitable for use, together with the first image, as a stereoscopic image pair.
