Abstract: For example, a controller of an Active Acoustic Control (AAC) system may be configured to process input information including AAC configuration information, and a plurality of noise inputs representing acoustic noise at a plurality of noise sensing locations. For example, the controller may be configured to process the input information to determine a sound control pattern to control sound within a sound control zone based on the plurality of noise inputs. For example, the controller may include a Neural-Network (NN) trained to generate an NN output based on an NN input, wherein the NN input is based on the AAC configuration information. For example, the controller may be configured to generate the sound control pattern based on the NN output, and to output the sound control pattern to one or more acoustic transducers.

Abstract: Surgical apparatus includes a transducer (50) configured to be inserted into a cavity (28) inside a bone (22) within a body of a living subject and to engage an inner wall of the cavity at a selected location within the cavity. A drive circuit (38) is coupled to apply a drive signal to the transducer so as to cause an echogenic movement of the bone at the selected location.

Abstract: According to one example there is provided apparatus for curing ink on a substrate. The apparatus comprises a substrate support, a curing sheet positionable above the substrate support to create a gap between a substrate on the substrate support and the curing sheet. The apparatus further comprises an oxygen-depletion mechanism for reducing the oxygen level in the gap and an ultra-violet, UV, radiation source to apply UV radiation through the curing sheet to a substrate on the substrate support.

Abstract: Examples are provided of plural light-emitting diodes (LEDs) arranged as vectors within an array. The vectors are individually drivable by way of a controller. A sensor scans the array and individual energy output values are correlated to electrical drive currents for each vector. The correlated data is recorded and used to control the vectors such that an equalized or uniform photonic energy profile is incident upon a media positioned as a target with respect to the LED system.

Abstract: An image forming apparatus includes an ink applicator unit to selectively apply ultraviolet (UV) curable ink on a media, a media support unit to support the media to receive the UV curable ink, and a UV radiation curing device to cure the UV curable ink on the media. The UV radiation curing device includes a UV radiation source module to emit an electromagnetic spectrum and a dispersion member. The dispersion member may separate ultraviolet electromagnetic radiation subtype C (UVC radiation) from at least one of ultraviolet electromagnetic radiation subtype A (UVA radiation) in the electromagnetic spectrum and ultraviolet electromagnetic radiation subtype B (UVB radiation), apply the UVC radiation to the UV curable ink on the media, and subsequently apply the at least one of the UVA radiation and the UVB radiation after the UVC radiation is applied to the UV curable ink on the media.
