  • Publication number: 20250217540
    Abstract: A method for defining antenna in module (AiM) placement within a user device can include configuring a simulation of antenna gain of antenna in module (AiM) components. The simulation can include as an output a cumulative distribution function (CDF) representing AiM coverage. The method can include identifying a first parameter of a set of antenna in module (AiM) placement parameters that has a largest effect on an antenna performance criterion observed in the simulation. The method can include adjusting other parameters based on the first parameter and specifying final placement of the AiM. An apparatus can include antennas and a radio front end including active circuitry and passive circuitry. The passive circuitry can be energized by a signal at a center frequency for the apparatus. The passive circuitry can store electrical charge and power on the active circuitry when charge reaches a threshold.

  • Publication number: 20220230643
    Abstract: Techniques for teleconferencing with enhanced audio during low-quality connection conditions are disclosed. In the illustrative embodiment, a user of a compute device is teleconferencing with users of one or more remote compute devices. The compute device monitors a connection quality with a remote compute device. If the connection quality drops below a threshold, risking gaps in the audio data, the compute device generates speech code data that can be used to fill in the gaps in the audio data. The remote compute device can use the speech code data to augment the audio data by using a voice model to create additional audio data based on the speech code data.

  • Patent number: 9906324
    Abstract: Selective deciphering of a received signal, as taught herein, provides a number of advantages, including greater efficiency through the elimination or at least reduction of wasted decoding cycles. The technique, such as practiced in a user equipment or other wireless communication device, capitalizes on the advantageous recognition herein that the demodulation results obtained for at least some types of received data blocks may be inspected or otherwise evaluated for characteristic patterns that are indicative of whether the data block was or was not ciphered for transmission. That evaluation informs the selective deciphering decision.
