Automatic hearing aid adaptation over time via mobile application


A hearing assistance system for delivering sounds to a listener provides for programming of a hearing assistance device, such as a hearing aid, using a communication link with a secondary device such as a smartphone. An example hearing assistance system may compensate for a patient's hearing deficit in a gradually progressing fashion over a configured period of absolute time, device operation time, or a combination of absolute and operation time.

Acoustic camera


Apparatus for generating accurate 3-dimensional images of objects immersed in liquids including optically opaque liquids which may also have significant sound attenuation, is described. Sound pulses are caused to impinge on the object, and the time-of-flight of the reflected sound is used to create a 3-dimensional image of the object in almost real-time.

Imaging apparatus and controlling method therefor, and lens unit and controlling method therefor, and imaging system


In a camera unit that is mountable to a lens unit having a focus lens, an af signal processing unit generates an af evaluation value from an imaging signal obtained by an imaging element, and a camera control unit generates drive information for moving the focus lens to an in-focus point using the af evaluation value and transmits the drive information to the mounted lens unit. The camera control unit transmits drive information including a focus lens position served as a reference for micro vibration and an amount of movement of the focus lens indicated by shift amount of an image plane with reference to the focus lens position to a lens unit..

Imaging apparatus and imaging system


Because a conventionally known imaging apparatus includes a buffer element for each signal processing circuit, the number of buffer elements increases in proportion to the number of signal processing circuits. The delayed supply of a drive signal within a group of a plurality of signal processing circuits may require the operation timing margin to be set longer.
