  • Publication number: 20240044674
    Abstract: A rotary encoder for providing a control signal in dependence upon an angular position of a controller rotatable about an axis of rotation. The rotary encoder includes a component for rotation with said controller about said axis of rotation. The rotary encoder also includes a radiation source and detector arrangement configured to direct radiation towards a target region and generate a detector signal dependent upon radiation reflected from within that target region. The rotary encoder further includes a computer processor configured to process said detector signal to determine a measure of distance or change of distance to a reflecting surface region within said target region, and to use said measure to provide said control signal. The component defines a reflecting surface that passes through said target region such that a reflecting surface region is present within said target region with a distance that varies with the angular position.

  • Patent number: 11692813
    Abstract: Optoelectronic modules operable to measure proximity independent of object surface reflectivity and, in some implementations, operable to measure characteristics (such as surface reflectivity or absorptivity) of stationary or moving objects are disclosed. The optoelectronic modules are operable to determine, for example, pulse rate, peripheral blood circulation, and/or blood oxygen levels of moving objects, such as the appendage of a user, in some instances. The optoelectronic modules can be used to measure peripheral blood circulation, for example, when a user of the optoelectronic module is engaged in physical activity, such as walking, running or cycling.

  • Patent number: 11536937
    Abstract: Light-emitting optoelectronic modules operable to generate an emission characterized by reduced speckle can include a coherent light source, a diffuser, and a Fresnel element. The coherent light source is operable to generate a coherent emission, characterized by a coherence length, incident on the diffuser. The diffuser is characterized by a divergence angle. The divergence angle is the angle between a first path-length from the diffuser to a Fresnel element and a second path-length from the diffuser to the Fresnel element, wherein their difference defines a path difference. In some instances, the path difference is substantially larger than the coherence length.

  • Patent number: 11537217
    Abstract: Techniques are described for use with a wide range of consumer and other electronic devices to facilitate a user's control of such features as volume, as well as song, channel or page selection, depending on the application. A method includes emitting light out of a module, receiving signals from light detectors in the module, wherein the signals represent, at least in part, light reflected by a person's finger or other object passing in front of the light detectors, detecting movement of the person's finger or other object based on the received signals, and controlling a feature of a device in response to the detected movement.

  • Publication number: 20220128688
    Abstract: An optical sensor module uses polarized light such that, in some instances, crosstalk effects caused by light reflected from a cover glass or from a thin smudge layer on the cover glass can be eliminated, or at least reduced, by directing light of a first polarization through the cover glass toward a target and selectively detecting, in the module, light of a second polarization that is orthogonal to the first polarization.

  • Patent number: 11307087
    Abstract: The present disclosure is directed to optoelectronic modules with substantially temperature-independent performance characteristics and host devices into which such optoelectronic modules can be integrated. In some instances, an optoelectronic module can collect proximity data using light-generating components and light-sensitive components that exhibit temperature-dependent performance characteristics. The light-generating components and light-sensitive components can be configured such that they exhibit complementing temperature-dependent performance characteristics such that the operating performance of the optoelectronic module is substantially temperature independent.

  • Publication number: 20220113464
    Abstract: Fabricating light guide elements includes forming a first portion of the light guide element using a replication technique (104), and forming a second portion of the light guide element using a photolithographic technique (106). Use of replication can facilitate formation of more complex-shaped optical elements as part of the light guide element. The replication process sometimes results in the formation of a “yard,” or excess replication material, which may lead to light leakage if not removed or smoothed over. In some instances, at least part of the yard portion is embedded within the second portion of the light guide element, thereby resulting in a smoothing over of the yard portion.

  • Publication number: 20220035478
    Abstract: An apparatus, e.g. a proximity sensor module (10), for optical distance sensing includes a target surface (25) having a non-uniform design including a high-reflectivity region and a low-reflectivity region for light of a particular wavelength. The position of the target surface (25) is displaceable within the apparatus. The apparatus includes a light source (12) operable to emit light at the particular wavelength toward the target surface (25), and a photodetector (14) operable to sense at least some of the light emitted by the light source and subsequently reflected by the target surface (25). A processor is operable to correlate an output from the photodetector (14) with a distance to the target surface (25). A wall (22) may separate the light source (12) and photodetector (14) from one another, which can help reduce internal optical crosstalk.

A region (R) within which the ball (2) can move is limited by at least the rolling surface (R) and the further surface (F). And the light emitters (E) and detectors (D) are arranged outside the region (R) for emitting light through the rolling surface (R) into said region and detecting light exiting the region (3) through the rolling surface (R) or for emitting light through the further surface (F) into said region (R) and detecting light exiting said region (R) through the further surface (F).
