Abstract: An adjustable fluid-filled lens or minor assembly 100 comprising a fluid-filled envelope and a supporting structure therefor; the fluid-filled envelope being constituted by a first wall that is formed of a distensible elastic membrane 15 having an exterior optical surface of variable focusing power, a second wall 18 that is spaced from the first wall on a z-axis, and a collapsible peripheral side wall 17 that extends between the first and second walls, and being filled with a substantially incompressible fluid 16; a membrane holding structure 14 that is attached to a peripheral edge of membrane 15 for holding the membrane under tension; and one or more selectively operable actuator assemblies r1, r2, r3 for moving one or more corresponding regions of the peripheral edge of the membrane on the z-axis towards and away from the second wall 18 for controlling the profile of the peripheral edge of the membrane; wherein the or each actuator assembly comprises a connecting member 91, 92, 93 that is attached to the m

Abstract: An augmented reality display unit for use in an augmented reality headset or the like comprising front and rear variable focusing power compression liquid lens assemblies (220, 230) in mutual optical alignment on an optical axis (O), a transparent waveguide display (240) interposed between the front and rear liquid lens assemblies (220, 230) and a selectively operable adjustment mechanism for adjusting the focusing powers of the front and rear compression liquid lens assemblies (220, 230); wherein each of the front and rear compression liquid lens assemblies (220, 230) comprises a fluid-filled envelope (225, 235) having a first wall formed by a distensible elastic membrane (226, 236) that is held under tension around its edge by a peripheral support ring, a second substantially rigid wall (223, 233) formed by or supported on an inner surface of a transparent plate or a hard lens of fixed focusing power, and a collapsible side wall (227, 237), the membrane forming an optical surface of variable optical power,

Abstract: Embodiments of a method (e.g., for operating a robotic device such as a dog device, etc.) can include: receiving one or more inputs (e.g., sensor input data, etc.) at a dog device (e.g., at one or more sensors of the dog device; a robotic dog device; etc.) from one or more users and/or other suitable entities (e.g., additional dog devices; etc.); determining one or more events (and/or a lack of one or more events), such as based on the one or more inputs (and/or a lack of one or more inputs); processing (e.g., determining, implementing, etc.) one or more scenes based on the one or more events (and/or lack of one or more events); and/or performing one or more output actions with the dog device, based on the one or more scenes (e.g., individual scenes; scene flows; etc.).
