Abstract: An apparatus for performing optometric measurements includes an opto-adjustable lens, the optical power of which is adjustable, with the lens being controlled by a periodic signal configured for producing a periodic optical power wave over time. The apparatus also includes a component for the adjustment of the mean value of the periodic optical power wave. The apparatus further includes an optical projector system for projecting a plane of the opto-adjustable lens onto a plane external to the apparatus, and in that the periodic signal has an amplitude such that it produces an amplitude of the periodic optical power wave corresponding to a chromatic difference of focus between a first wavelength and a second wavelength of visible light which passes the opto-adjustable lens. A system for the performance of optometric measurements and a method for adjusting the optical power of an adjustable lens are related to the apparatus.

Abstract: A device for measuring the optical power of an optical test system includes an optical-object-generating assembly, a support for the optical test system, a digital image detector, and a deflector assembly. The deflector assembly is intended to generate a lateral movement in respect of the initial optical image, thereby producing a shifted optical image and a reference optical image. The digital image detector captures the shifted optical image and the reference optical image in at least one digital image containing data relating to the lateral movement. The device also includes a processing component to calculate the optical power of the optical test system from the data relating to the lateral movement.

Abstract: Methods, systems, and ophthalmic devices are described for correcting a misperception of depth of a moving object. An example ophthalmic device may comprise a first lens having a first optical characteristic that increases a distance of a focal point of a first eye. The ophthalmic device may comprise a second lens having a second optical characteristic that decreases a distance of a focal point of a second eye. The second lens may have a third optical characteristic that reduces a misperception of a distance of an moving object.

Abstract: A safety actuator apparatus for a baling machine comprising an extension member coupled to a baling machine having at least one baling chamber, the extension member having at least one end extending outwardly from the baling machine and a support member comprising a safety actuated retention component that aligns with and is configured to contact and restrain the at least one end of the extension member. The apparatus further comprises a detection device for identifying the presence of an obstacle in a predetermined path or a trajectory of movement of at least one component of the baling machine and a communication device configured to send a signal from the detection device to the safety actuated retention component and engage the safety actuated retention component to restrain the movement of at least one component of the baling machine.
