Abstract: Example techniques may involve guest access to a media playback system. A guest may use a guest control device, such as a smartphone or tablet, to control aspects of a host's media playback system. In addition, the guest may temporarily register their user account of a streaming audio service with the host's media playback system, which enables playback of audio content from that service by one or more playback devices of the media playback system. When the guest control device de-registers from the host's media playback system, retrieval of audio content from the streaming audio service is disabled.

Abstract: In-situ optical spectroscopic monitoring, characterization and feedback control of extraction and purification processes of compounds such as oils, alkaloids, flavonoids, terpenes and cannabinoids derived from plant material are described. Liquids from an extraction or purification process flow down an optically transparent tube, such as one made of glass. An in-situ optical monitoring assembly is configured to be mounted onto the tube to measure optical properties of the liquid extract or liquid condensate as it flows in the tube. Optical properties of the flowing liquid may include optical transmittance, reflectance, photoluminescence, scattering, absorbance, turbidity, nephelometry, polarimetry and colorimetry. The output of the optical monitoring assembly can be used to display spectral and other about the flowing liquid, set alarms to notify an operator of a predetermined condition such as a set point, and used to control extraction or purification process.

Abstract: Methods and apparatus relating to very large scale FET arrays for analyte measurements. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in hydrogen ion concentration (pH), changes in other analyte concentration, and/or binding events associated with chemical processes relating to DNA synthesis.

Abstract: Apparatus and methods are disclosed, including using a memory controller to partition a memory array into a first portion and a second portion, the first portion and second portion having non-overlapping logical block addressing (LBA) ranges. The memory controller assigns a first granularity of a first logical-to-physical (L2P) mapping table entry for the first portion of the memory array designated for a first usage, and a second granularity of a second L2P mapping table entry for the second portion of the memory array designated for a second usage, where the second granularity is not equal to the first granularity. The memory controller stores the first granularity and the second granularity in the memory array, and stores at least a portion of the first L2P mapping table entry and the second L2P mapping table entry in an L2P cache of the memory controller.

Abstract: The present disclosure relates to devices and processes for monitoring attributes of a user's physical activity (e.g., workout) or inactivity, and to user interfaces (e.g., an activity indicator) for displaying the same. In some examples, a device determines whether physical activity corresponds to a first type based on a first set of criteria, and whether physical activity corresponds to a second type based on a second set of criteria. In some examples, the device controls an inactivity timer that measures user's inactivity. In some examples, the device displays a first visual representation of an attribute or amount of a first type of physical activity, and a second visual representation of an attribute or amount of a second type. In some examples, the device displays a third visual representation of an attribute or amount of a third type of activity. In some examples, the third visual representation corresponds to user's inactivity.

Abstract: Techniques for training a machine learning model are described herein. For example, the techniques may include implementing a cross batch normalization layer that generates a cross batch normalization layer output based on a first layer output during training of the neural network. The training may be based on a local batch of training examples of a global batch including the local batch and at least one remote batch of training examples. The cross batch normalization layer output may include normalized components of the first layer output determined based on global normalization statistics for the global batch. Such techniques may be used to train a neural network over distributed machines by synchronizing batches between such machines.
