Abstract: An example computing system may be configured to cause one or more playback devices located in a location of a commercial environment to play back an advertisement. The example computing system may also be configured to receive an indication that a user device is detected proximate to the location, during playback of the advertisement. The example computing system may also be configured to, after receiving the indication that the user device has been detected, receive an indication of a purchase of the subject of the advertisement, the purchase associated with the user profile. The example computing system may also be configured to, based on (i) the indication that the user device has been detected during play back of the advertisement and (ii) the indication of the purchase of the subject of the advertisement, cause a content service account associated with the computing system to be updated.

Abstract: An example computing system may be configured to receive an indication that a user device has been detected in a commercial environment and to determine a first set of musical preferences associated with the commercial environment. The example computing system may also be configured to determine a user profile associated with the user device and to determine a second set of musical preferences associated with the user profile. The example computing system may also be configured to, based on at least (i) the first set of musical preferences associated with the commercial environment, and (ii) the second set of musical preferences associated with the user profile, determine one or more media items for playback and then cause one or more playback devices in the commercial environment to play back the one or more media items.

Abstract: An automated boot failure prevention and recovery circuit includes one or more non-transitory computer-readable media having computer-executable instructions embodied thereon, a processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to electrically disconnect a memory from a power source, short the memory to ground for a predetermined period of time to adjust memory content from a stochastic state to a machine-tolerable state or an acceptable non-failure state. The processor is further configured to execute the computer-executable instructions to electrically disconnect the memory from the ground, and electrically reconnect the memory to the power source. The processor is further configured to execute the computer-executable instructions to apply a load across the power source, acquire power source information, and notify the user of the battery charge status to preclude loss of memory data.
