  • Patent number: 11646384
    Abstract: An optoelectronic module may include one or more non-rectangular optoelectronic dies e.g., light emitting diodes and photodiodes, arranged to maximize the usage of surface area when mounted to a base circuit board. Multi-axis and non-orthogonal axis dicing processes can be used to form the dies which have non-rectangular shapes.

  • Publication number: 20230099638
    Abstract: Robust estimation of temperatures inside and outside a device can be achieved using one or more absolute temperature sensors optionally in conjunction with thermopile heat flux sensors. Thermopile temperature sensing systems can measure a temperature gradient across two locations within the device, to estimate absolute temperature at locations that are impractical to measure using absolute temperature sensors. Using heat flux models associated with the device, the thermopile temperature sensing system can be used to estimate temperature associated with objects that contact an outer surface of the device, such as a user's skin temperature. Additionally, the thermopile temperature sensing system can be used to estimate ambient air temperature. Within a device, temperature measurements from the thermopile temperature sensors can be used to compensate sensor measurements, such as when the accuracy or reliability of a sensor varies with temperature.

  • Publication number: 20230085860
    Abstract: One embodiment described herein takes the form of a wearable electronic device, such as a watch, including a housing, a memory and a processor located in the housing, and three or more sensors. Each sensor of the three or more sensors is configured to generate a measurement of a parameter. Each sensor of the three or more sensors is located in a different region in the housing. The processor is configured to execute instructions stored in the memory. In response to execution of the instructions by the processor, the processor is configured to generate an adjusted measurement of the biometric parameter using at least the measurements of the parameter generated by the three or more sensors. The parameter is a temperature, and the biometric parameter is a body temperature of a user.

  • Publication number: 20230093738
    Abstract: Disclosed herein are electronic devices, including wearable electronic devices, and components and configurations thereof, having one or more temperature sensors separated from the point of contact of the electronic device and an object, such as a user, whose temperature is being measured. In some embodiments, the electronic device includes both a temperature sensor and a light (visible, UV, and/or IR) emitter and sensor. Various embodiments are disclosed by which a temperature sensor may be shielded or separated from a light emitter/detector. A spacer may be used to separate the temperature sensor from the device's housing that contacts the object. The spacer may include a thermal path from the housing to the temperature sensor, and may be opaque to the light detected by a light detector.

  • Patent number: 11573351
    Abstract: An electronic watch includes a frame and a cover. The cover is attached to the frame, and the frame and cover at least partially define an interior volume of the electronic watch. An optical sensor assembly including a light emitter and a light receiver is positioned within the inter volume of the frame. An optical barrier is positioned between the optical sensor assembly and the cover and includes a magnetic material that forms a light blocking-wall between the light emitter and the light receiver. The magnetic material is configured to removably couple the electronic watch with a charging device via a magnetic attraction between the magnetic material and a magnetic component of the charging device.

  • Patent number: 10353506
    Abstract: Structures and methods are disclosed for an electronic device having an input surface that uses dual sensors to measure forces applied to the input surface. The forces can be estimated over a greater range of values than would be possible with either sensor alone. A second sensor can be used after a first sensor has reached a limit. A first sensor can be a strain sensor and a second sensor a pressure sensor. Both sensors may be resistance based, with signals from both sensors can be combined and measured by processing circuitry. Each sensor type may be part of planar arrays disposed beneath the input surface.

  • Patent number: 9694422
    Abstract: In one embodiment, a method is provided for fabrication of a semitransparent conductive mesh. A first solution having conductive nanowires suspended therein and a second solution having nanoparticles suspended therein are sprayed toward a substrate, the spraying forming a mist. The mist is processed, while on the substrate, to provide a semitransparent conductive material in the form of a mesh having the conductive nanowires and nanoparticles. The nanoparticles are configured and arranged to direct light passing through the mesh. Connections between the nanowires provide conductivity through the mesh.
