Abstract: An apparatus includes a chamber and an intake device configured to control a flow of fluid into the chamber. The fluid comprises particles; a resonance device is configured to resonate the chamber to provide an acoustic standing wave within the chambers. The frequency of the standing wave is selected to cause particles above a specific size to collect at a node of the standing wave.

Abstract: Methods, apparatuses, and computer program products are disclosed for providing a multiphase pumping mechanism configured for multiphase cooling of electrical charging circuitry. In the context of an apparatus, the apparatus includes a thermoelectric cooling device having first and second opposed surfaces and a fluid circulation path having first and second branches in thermal communication with the first and second surfaces, respectively, of the thermoelectric cooling device. The fluid circulation path is configured to control flow of fluid therethrough such that the fluid alternately flows through the first and second branches. The first branch of the fluid circulation path is also configured to be in a thermal communication with at least one first component of a mobile electronic device in order to absorb heat and correspondingly cool the at least one first component of the mobile electronic device.

Abstract: A method, apparatus and computer program product enhance audio quality during a voice communication session, enhancing audio quality for a device of a remote user. The apparatus can comprise a processor, a memory, and a computer program code, and can be configured to receive and weight audio signals based on signal attributes such that audio signals can be adjusted and adjusted signals mixed to form a composite audio signal. In a method, a processor receives audio signals from audio sensors around a room, selects one or more audio signals based on audio signal attributes, and adjusts or causes the adjustment of the one or more audio signals based on the audio signal attributes. The method can also include causing the adjusted audio signals to be mixed to form a composite signal, and causing the composite signal to be communicated to a device of a remote user.
