Abstract: A food wash reference fluid delivery apparatus includes a portable reference fluid reservoir comprising an inlet and an outlet and configured to store a reference fluid that includes a predetermined concentration of an analyte, a pump fluidly coupled to the outlet of the portable reference fluid reservoir and configured to pump the reference fluid from the outlet of the portable reference fluid reservoir, a sensor connector configured to fluidly couple with a sensor positioned along a fluid flow path of the food wash system, a sensor fluid line configured to provide the reference fluid from the pump to the sensor connector, an inlet fluid line configured to provide the reference fluid from the pump to the inlet of the portable reference fluid reservoir, and a valve configured to adjustably control a fluid flow rate of the reference fluid through the sensor fluid line and the inlet fluid line.

Abstract: Described herein are systems and methods for context aware content distribution. Content such as e-books, presentations, audio, video, applications, and so forth may be distributed to user devices after establishing a trust relationship. An invitation to provide content may be sent to a user device based on the context of the user device, such as proximity to pre-determined devices, location, and so forth. Upon acceptance of the invitation to opt-in to receiving content, a trust relationship may be established which provides for the transfer of content to the user device.

Abstract: Detection and prevention of unauthorized exchange of information between users of user devices is disclosed. Monitoring data associated with respective information received by the user devices from respective users may be received. Position information indicating proximity or relative positions of the devices may also be received. The monitoring data and/or the position information may be analyzed to determining whether unauthorized information exchange between users may be occurring. One or more metrics indicating a likelihood that unauthorized information exchange is occurring may be generated based on the analysis of the monitoring data and/or the position information. A generated metric may be compared to an associated threshold and preventive measures for deterring unauthorized information exchange may be identified based on a result of the comparison.

Abstract: This disclosure describes, in part, techniques for managing access to a fleet account of mobile electronic devices. For instance, an administrator of a business and educational institution may place an order with an offering service to purchase a large number of eBook reader devices. The offering service identifies that the business and educational institution is ordering a fleet of devices. Furthermore, each of the devices ordered are associated or registered to a managed or fleet account controlled by the administrator of the business and educational institution. The techniques described herein prevent an individual user of a fleet device from de-registering the device from the managed account, and also allow an account administrator to alter preferred settings of the managed account. Further, techniques are described for allowing a user of a device to opt-in or associate their device with the account.
