Abstract: Systems and methods for determining cell type are provided. Information is obtained including, for each spot in a set of capture spots, a position in a tissue image and analyte abundances in the tissue. A current iteration of cell types, set to a maximum number, is determined using the analyte abundances, where each cell type has an abundance value for each analyte. When the current iteration exceeds a minimum number of cell types, a distance metric between each cell type in the current iteration is determined based on cell type analyte abundance values and the current iteration is reformed by merging a first and second cell type having a smallest distance metric. The procedure is repeated until the current iteration matches the minimum number. For each current iteration, output is determined including, for each cell type, for each spot, a proportion of cells in the spot having the cell type.

Abstract: A method performed by an audio source device. The method obtains an input audio signal and determines a sound output level of a headset based on the input audio signal, a user volume setting, and a sound output sensitivity of the headset. The method determines whether the sound output level is above a threshold. In response to determining that the sound output level is above the threshold, a scalar gain is applied upon the input audio signal to produce an output audio signal for output by the headset.

Abstract: A device and a corresponding method are provided to tune parameters of an echo control process without re-initializing the echo control process and without interrupting a playback process. A state of the device and environment around the device is computed during use of the device given information from sensors. Such sensors can give information on the position of the device, the orientation of the device, the presence of a proximate object, or handling of the device resulting in occlusion of microphones and loudspeakers, among other things. The computed state of the device is mapped to an associated device state code from among a plurality of device state codes. The parameters of the echo control process are tuned either according to the associated device state code, or a change in such a code, during use of the device.
