Abstract: The present disclosure relates to a method and a corresponding device (1) for providing an eye metric. The device comprises a display unit (3), producing a visual stimulus (7) to an eye, a feedback unit (9) measuring a response to the stimulus, and an analysing unit (11), outputting a metric result. The device is configured to produce a recurring bleaching impulse together with the stimulus wherein the bleaching impulse is repeated with a frequency greater than 0.3 Hz. This serves to keep the cones of the eye's retina in a saturated state, and the produced metric may be useful in apparatuses for eye evaluation.

Abstract: The present disclosure relates to a device for visual field testing 11, which maps eye function of a test subject, the device comprising a display unit 17 displaying stimuli 23 to the test subject, and an eye tracking unit 19 detecting eye motions in response to the displayed stimuli. The display unit 17 displays at least a first 23 and a second 25 peripheral stimulus at different sectors in relation to a point of fixation 27 at the same time and the eye tracking unit determines which of the first and second stimulus is first gazed upon by the test subject. This allows different parts of the retina to compete with regards to retinal sensitivity and allows for a precise and efficient visual field testing.

Abstract: The present disclosure relates to a device for providing an eye metric, comprising a display unit (7), producing a visual stimulus (13) to an eye. An eye-tracking unit (9), measures the eye's movements in response to the stimulus, and an analyzing unit, outputting a metric result. The display unit (7) produces a moving stimulus with at least one varying stimulus parameter such as a symbol size, and the eye-tracking unit (9) detects when the eye loses visual contact with the stimulus. The analyzing unit provides a metric result based on the value of the stimulus parameter at the time when loss of visual contact was detected.

Abstract: The present disclosure relates to a method and a device for acquisition of a metric of an eye (1) located in an acquisition space (29). The device comprises at least one light source (11) configured to emit light towards the acquisition space, a camera (15) configured to receive light from the acquisition space to (29) generate image data, and an analyzing unit (14) configured to extract at least one metric from the image data. The camera (15) is configured to receive light from the acquisition space via at least two light paths (17, 19) which are differently angled with respect to the optical axis of the camera, the light of at least one path being received via a first mirror (21). The camera receives light from an overlapping portion of the acquisition space via the first and second paths, as to allow the camera to receive at least two representations of a single eye. This metric may be used for e.g. eye tracking or autorefraction/accomodation.

Abstract: Disclosed is a method for producing wear-resistant layers on materials of barrier-layer-forming metals, such as aluminum, magnesium and titanium and their alloys and mixtures, preferably aluminum or its alloys, by means of laser treatment, the material surface being exposed to a laser irradiation in the presence of an atmosphere containing oxygen in such a way that the upper or outer layer of the material surface reacts with the oxygen to form an oxide of the metal constituting the material, preferably aluminum oxide, and the layer of the material lying under that is remelted without reacting with the atmosphere containing oxygen. This results in a multilayer structure with excellent wear-resistant properties, including excellent corrosion resistance, excellent abrasion resistance and extreme hardness that does not exhibit any brittleness as a result of the hardness gradient within the layer structure.

Abstract: An RF module having an RF antenna integrated with a RF shielding part is disclosed. The arrangement includes a tuning mechanism for tuning the RF antenna according to a Voltage Standing Wave Ratio (VSWR) specification to thereby tolerate bigger tolerances of the other components on the printed circuit board. More space on the printed circuit board is also obtained as well as avoiding RF losses in transmission lines and soldering connections to an external antenna. A metallic shield can be produced from a single metallic sheet or a molded metallized piece being formed to a desired shape, thereby forming an antenna radiator member integrated with the screening portion of the metallic shield, the antenna radiator member extending over or resting against a supporting element. The VSWR of the antenna radiator member can be tuned by twisting, rotating or shifting the supporting element, which rests on a printed circuit board underlying the antenna device and carrying the electronic components of the RF module.
