Abstract: The sensor (1) for determining an orientation of the sensor in a gravity field comprises a ball (2) and a rolling surface (R) describing a generally concave shape on which the ball can roll inside the sensor. A further surface (F) is arranged opposite said rolling surface, and a light emitter (E), a light detector (D) and another light emitter or detector is provided. 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). Corresponding measuring methods and manufacturing methods are described, too.

Abstract: Image sensor modules include primary high-resolution imagers and secondary imagers. For example, an image sensor module may include a semiconductor chip including photosensitive regions defining, respectively, a primary camera and a secondary camera. The image sensor module may include an optical assembly that does not substantially obstruct the field-of-view of the secondary camera. Some modules include multiple secondary cameras that have a field-of-view at least as large as the field-of-view of the primary camera. Various features are described to facilitate acquisition of signals that can be used to calculate depth information.

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.

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. The light source (12) and photodetector (14) are mounted and electrically coupled to a substrate (16) that, in turn, can be mounted and electrically coupled to a printed circuit board (PCB) (18) of a host device. The light source (12) and photodetector (14) are surrounded laterally by a spacer or housing wall (20). The target surface (25) may be the backside of a touch interactive display screen (24) in the host device, e.g., a portable computing device such as a smartphone, tablet, wearable device, personal digital assistant (PDA), or personal computer. Circuitry (28) can be implemented, for example, as an integrated circuit chip or other processor and may include software and/or a look-up table stored in memory that allows the circuitry (28) to correlate the measured photodetector signal to a distance. When pressure is provided on the display screen (24) (e.g., by a person pressing her finger on the screen), the display screen is displaced slightly in the direction of the substrate (16) on which the light source (12) and photodetector (14) are mounted. As a result of the displacement, the intensity of light detected by the photodetector (24) changes. The signal measured by the photodetector (24) can be correlated to a distance value. If the distance value is within a specified range (or changes by at least a specified amount), for example, it can trigger some further action in the host device.

Abstract: Optoelectronic modules include a silicon substrate in which or on which there is an optoelectronic device. An optics assembly is disposed over the optoelectronic device, and a spacer separates the silicon substrate from the optics assembly. Methods of fabricating such modules also are described.

Abstract: Compact optoelectronic modules are described that, in some implementations, can have reduced heights, while at the same time having very little optical crosstalk or detection of stray light. An optoelectronic module having optical channel can include a support on which is mounted an optoelectronic device arranged to emit or detect light at a particular one or more wavelengths. The module has a cover including an optically transmissive portion over the optoelectronic device. The optically transmissive portion is surrounded laterally by sections of the cover that are substantially non-transparent to the one or more wavelengths. A passive optical element is present on a surface of the optically transmissive portion. A spacer separates the support from the cover. The cover can be relatively thin so that the overall height of the module is relatively small.

Abstract: An optoelectronic module includes a first light emitter operable to emit radiation at a first wavelength toward an object outside the module. The module also includes demodulation pixels operable to detect radiation of the first wavelength reflected from the object. One or more processors are operable to determine a distance to the object based on the radiation detected by the demodulation pixels. The module is further operable to perform a supplemental measurement other than distance.
