  • Publication number: 20180143858
    Abstract: A first quality of service identifier is assigned to each subtask associated with each node of a compute workflow, the first quality of service identifier indicative of a level of quality of service associated with each node. A planned resource requirement is assigned to each subtask, the planned resource requirement indicative of a total amount of system resources required to complete each subtask. A resource allocation plan is generated for each subtask, the resource allocation plan indicative of a distribution of the system resources over time in at least one resource manager. The resource allocation plan and the first quality of service identifier are output to the at least one resource manager for enforcement of the level of quality of service on one or more jobs submitted for each node through at least one workflow orchestrator external to the at least one resource manager.

  • Patent number: 9891110
    Abstract: A system includes a temperature sensor and a distance sensor. The distance sensor provides an indication of distance between the temperature sensor and an object to be measured. By determining the distance between the temperature sensor and the object, the system determines whether the object is sufficiently close to the temperature sensor to make an accurate temperature measurement, such as by determining whether the object completely fills the field of view of the sensor. In an implementation, the distance sensor includes a light source and a photodetector configured to detect light having wavelengths that correspond to those generated by the light source.

  • Patent number: 9851258
    Abstract: A sensor package having a thermopile sensor and a reference thermopile sensor disposed therein. In one or more implementations, the sensor package includes a substrate, a thermopile sensor disposed over the substrate, a reference thermopile sensor disposed over the substrate, and a lid assembly disposed over the thermopile sensor and the reference thermopile sensor. The lid assembly includes a transparent structure that passes electromagnetic radiation occurring in a limited spectrum of wavelengths and an electromagnetic blocker disposed over the lid assembly. The electromagnetic blocker defines an aperture over the thermopile sensor such that at least a portion of the electromagnetic blocker is positioned over the reference thermopile sensor. The electromagnetic blocker is configured to at least substantially block the electromagnetic radiation occurring in a limited spectrum of wavelengths from reaching the reference thermopile sensor.

  • Patent number: 9846083
    Abstract: A sensor package can have a reference thermopile sensor and a reference temperature sensor disposed therein to determine an ambient temperature. In one or more implementations, the sensor package includes a substrate having a substrate surface, a reference thermopile sensor disposed over the substrate surface, a reference temperature sensor disposed over the substrate surface, and a lid assembly disposed over the thermopile sensor and the reference thermopile sensor. The lid assembly includes a structure having a transparent portion that passes electromagnetic radiation occurring in a limited spectrum of wavelengths. The reference thermopile sensor generates a reference thermopile sensor signal representing a difference between a temperature of the substrate surface and a temperature of a lid assembly surface. An external ambient temperature can be determined based upon the reference thermopile sensor signal.

  • Patent number: 9778099
    Abstract: The present disclosure describes systems, methods, and devices for estimating spectral contributions in ambient light. The present disclosure also describes systems, methods, and devices for compensating for field of view errors resulting from the user, contextual structures (e.g., buildings, trees, fixtures, or geological formations), atmospheric effects (e.g., ozone coverage, smog, fog, haze, or clouds), device structures, and/or device orientation/tilt relative to a light source being measured (e.g., sun, indoor/outdoor light emitter, or an at least partially reflective surface). The present disclosure also describes systems, methods, and devices for estimating spectral contributions in light or color measurements and accounting for field of view errors to obtain a refined estimate.

  • Patent number: 9534955
    Abstract: The present disclosure describes an ultraviolet (UV) sensor configured to detect a target UV spectrum (e.g., UVB spectrum). The UV sensor includes a first photodiode with a first UV spectral response and a second photodiode with a second UV spectral response. A filter layer having a graded spectral response is formed over the second photodiode, and the second UV spectral response is affected by a controlled parameter (e.g., thickness) of the filter layer. The UV sensor further includes a subtraction circuit coupled with the first photodiode and the second photodiode. The subtraction circuit is configured to provide a differential response based on a difference between the first UV spectral response and the second UV spectral response. The controlled parameter of the filter layer can be selected such that the differential response provides a detected spectral response of the target spectrum.

  • Patent number: 9330624
    Abstract: Electronic devices with a VCOM display panel are configured to provide a common voltage VCOM to a VCOM display panel backplane, referred to as a VCOM reference plane. The common voltage is supplied by a VCOM application circuit coupled to the VCOM reference plane. The VCOM application circuit includes a VCOM amplifier having a closed-loop gain. The VCOM application circuit is configurable to quickly adjust the closed-loop gain so as to adjust the settling characteristics of the common voltage VCOM output by the VCOM application circuit. The VCOM application circuit having adjustable closed-loop gain also reduces the amount of power to be dissipated, and therefore the amount of heat generation, in the VCOM amplifier.

  • Patent number: 9305506
    Abstract: Electronic devices with a VCOM display panel are configured to provide a common voltage VCOM to a VCOM display panel backplane, referred to as a VCOM reference plane. The common voltage is supplied by a VCOM application circuit coupled to the VCOM reference plane. The VCOM application circuit includes a linear amplifier, such as a Class AB amplifier, coupled to a switched transient assist circuit configured to output the common voltage. The switched transient assist circuit stabilizes the amplifier in the presence of large transient output currents but with minimized power dissipation and heat rise in the amplifier.

  • Publication number: 20150338273
    Abstract: Techniques are provided to furnish a light sensor that includes a filter positioned over a photodetector to filter visible and infrared wavelengths to permit the sensing of ultraviolet (UV) wavelengths. In one or more implementations, the light sensor comprises a semiconductor device (e.g., a die) that includes a substrate. A photodetector (e.g., photodiode, phototransistor, etc.) is formed in the substrate proximate to the surface of the substrate. In one or more implementations, the substrate comprises a silicon on insulator substrate (SOI). A filter (e.g., absorption filter, interference filter, flat pass filter, McKinlay-Diffey Erythema Action Spectrum-based filter, UVA/UVB filter, and so forth) is disposed over the photodetector. The filter is configured to filter infrared light and visible light from light received by the light sensor to at least substantially block infrared light and visible light from reaching the photodetector.
