Abstract: Apparatus and methods are described for use with a temporary progressive lens that is configured for a subject's temporary use based upon an initial progressive-lens optical design. While the temporary progressive lens is inside a frame that is configured to be worn by the subject, data are received from one or more sensors that are associated with the frame and that are configured to detect when the frame is removed from and/or repositioned on the subject's face, while the subject performs activities. Based upon the received data and reasons provided by the subject for the frame having been removed from and/or repositioned on the subject's face, an optimized optical design for the progressive lens is determined. Other applications are also described.

Abstract: Apparatus and methods are described for use with a frame (21) of glasses (18) that are to be worn by a wearer. A progressive lens (20) is configured to provide a far-vision corrective functionality and a near-vision corrective functionality. The progressive lens includes a bespoke, single-vision base lens (22) that is configured to provide at least a portion of the far-vision corrective functionality, the bespoke lens being formed so as to accommodate ophthalmic requirements of the wearer, and/or requirements of the glasses frame (21). The progressive lens further includes an additional lens (24) coupled to the bespoke, single-vision base lens (22), the additional lens (24) being configured to provide progressive near-vision corrective functionality. Other applications are also described.

Abstract: Apparatus and methods are described, including providing a temporary progressive lens (20) that is configured for a subject's temporary use, based upon an initial progressive-lens optical design. The lens is composed of a base lens (22) and an attached additional and removable progressive lens part (24) for test purposes. Data that are indicative of suitability of the optical design for activities that are performed by the subject are received, the data being generated during use of the temporary progressive lens by the subject. Based upon the received data, the optical design for a progressive lens for the subject is optimised, and the optimised optical design in output.

Abstract: Apparatus and methods are described including an additional lens (24) made from an amorphous viscoelastic material and having an optical design. A curvature of the additional lens (24) is changed such as to conform with a curvature of abase eyeglasses lens (22), without causing a loss of the optical design of the additional lens (24), by heating the additional lens (24) to a temperature at which a Tan Delta of the amorphous viscoelastic material is between 0.2 and 0.8, and shaping the additional lens (24). Subsequently, the additional lens (24) is adhered to the base eyeglasses lens (22). The optical design of the additional lens (24) is such that, upon being adhered to the base eyeglasses lens (22), the adhered base eyeglasses lens (22) and the additional lens (24) provide a combined lens (20) having a desired optical prescription. Other applications are also described.

Abstract: A body armor vest system including a wearable vest, a power source, a processor, at least one explosive charge, a multimodal sensor system and an inflatable protective hood, the power source, the processor and the explosive charge positioned on the wearable vest, the inflatable protective hood positioned on an upper portion of the wearable vest, the multimodal sensor system detecting the incoming projectile, the processor determining if the incoming projectile is a credible threat and deploying the inflatable protective hood and detonating the explosive charge if the detected incoming projectile is determined to be a credible threat.

Abstract: Apparatus and methods are described including a vacuum-plasma-jig (20) that receives an object (10) during application of a vacuum plasma-treatment to a first surface (12) of the object 10). A receptacle (22) and base (30) of the vacuum-plasma-jig (20) are shaped such that when the receptacle (22) receives a portion of a second surface (14) of the object (10), there is a hollow space (28) proximate to the portion of the second surface (14) of the object (10). The vacuum-plasma-jig (20) defines a channel (32) therethrough, a first end (34) of the channel (32) opening to an exterior of the vacuum-plasma-jig (20) and a second end (36) of the channel (32) opening to the hollow space (28), a ratio of a length of the channel in mm to a mean cross-sectional area of the channel in square mm being greater than 100:1. Other applications are also described.

Abstract: A system includes a communication interface and a processor. The processor is configured to identify a value of at least one feature of artificial intelligence (AI) infrastructure, to compare the value to a threshold that was defined responsively to a biological parameter, and in response to comparing the value to the threshold, to output, via the communication interface, an alert indicating that computational capabilities of the AI infrastructure are excessive. Other embodiments are also described.

Abstract: A method is provided for use with historical artifacts. A textile that contains hand-sewn stitching is identified among the historical artifacts, and one or more tied-off thread ends within the textile are identified. DNA is extracted from the tied-off thread ends. Other applications are also described.
