Abstract: A sensor mechanism in an environmental monitoring device provides sensor data that represents an environmental condition in an external environment that includes the environmental monitoring device. Then, a control mechanism in the environmental monitoring device determines, based on the sensor data, an alert associated with the environmental condition and/or the external environment. Moreover, an interface circuit in the environmental monitoring device provides, based on the alert, a service offer to an electronic device of an entity (such as a user or an owner of the environmental monitoring device, a tenant, a property owner and/or a property manager), where the service offer includes information associated with the environmental condition. Next, the environmental monitoring device receives, via the interface circuit, a response to the service offer from the electronic device, where the response authorizes a service based on the environmental condition.

Abstract: An interface mechanism in a system receives a service request for a service associated with an environment from an electronic device of an entity. In response to the service request, a control mechanism in the system identifies an environmental monitoring device within the environment, where the environmental monitoring device provides sensor data that represents an environmental condition in the environment, and the environmental monitoring device is associated with a second entity that is different from the entity and a third entity associated with the system. Moreover, the control mechanism provides, via the interface mechanism, a data request for the sensor data to the environmental monitoring device. Furthermore, in response to the data request, the interface mechanism receives the sensor data from the environmental monitoring device. Then, the control mechanism provides the service to the entity based on the environmental condition.

Abstract: A control mechanism in a system monitors inputs and outputs (such as sensor data representing one or more environmental conditions in one or more environments, sub-services in the services, and/or compensation) exchanged among components in combinations that provide the services in the environments, where the components in a given combination include at least one of: environmental monitoring devices in the environments and one or more of the partner electronic devices in the environments and/or service providers. Moreover, the control mechanism stores the monitored inputs and outputs, and analyzes the monitored inputs and outputs based on quality criteria and historical inputs and outputs exchanged within the combinations. Based on the analysis, the control mechanism identifies an instance in the inputs and the outputs of: incorrect sensor data and/or fraudulent compensation. Furthermore, the control mechanism performs a remedial action based on the identified instance.

Abstract: A computer that facilitates calibration of an environmental monitoring device is described. In particular, the computer may interact with an electronic device of a user of the environmental monitoring device to calibrate the environmental monitoring device. During the calibration, the computer provides user-interface information associated with a user interface that allows the user to select to select to monitor sound corresponding to an alarm output by a legacy device (such as a smoke detector) that is in an external environment that includes the environmental monitoring device. When the user selects to monitor a legacy device, the computer provides an instruction to the electronic device for the user to activate the legacy device. Then, the computer receives legacy-device information from the environmental monitoring device, specifying whether the legacy device was detected, a type of legacy device identified based on the monitored sound and/or a location of the legacy device.

Abstract: A sensor mechanism in an environmental monitoring device provides sensor data that represents an environmental condition in an external environment that includes the environmental monitoring device. Then, a control mechanism in the environmental monitoring device generates subsets of the sensor data based on data privileges of different entities, where the data privileges of at least some of the entities are different from each other, and at least some of the corresponding subsets of the sensor data are different. For example, the data privileges may specify: different spatial extents in the external environment monitored by the sensor mechanism; and/or different types of information associated with the external environment. Next, an interface circuit in the environmental monitoring device provides the subsets of the sensor data to electronic devices associated with the entities.

Abstract: A controller electronic device selectively associates one or more monitoring electronic devices and a viewing electronic device, so that the viewing electronic device can selectively access content acquired by the one or more monitoring electronic devices, such as captured images and/or measured acoustic information corresponding to sound in environments. In particular, the controller electronic device may receive messages with timestamps and current locations of a monitoring electronic device that is associated with the viewing electronic device. Based on a duration of time the monitoring electronic device is at a fixed or an approximately fixed location, the controller electronic device may establish the associations. For example, a maximum distance associated with the associations may increase as the duration of time increases.

Abstract: An environmental monitoring device that includes a switching mechanism is described. During operation of the environmental monitoring device, the switching mechanism (such as a switch) selectively electrically couples a first electrical-connection node and a second electrical-connection node. For example, using the switching mechanism, an electronic device having a power source may be selectively electrically coupled to a second electronic device having a rechargeable battery. The selective electrical coupling may be based on one or more measurements of an environmental condition in an external environment that includes the environmental monitoring device by a sensor mechanism in the environmental monitoring device. This environmental condition may be associated with charging of the rechargeable battery. In addition, a control mechanism in the environmental monitoring device selects a charging mode of the rechargeable battery based on the one or more measurements of the environmental condition.

Abstract: An electronic device that communicates input messages and output messages with another electronic device using a Bluetooth Low Energy communication protocol is described. In particular, the electronic device receives input messages using a predefined characteristic to convey input information associated with a set of input attribute types. A given input message includes one or more input-command characters specifying a given input attribute type in the set of input attribute types and, optionally, an input delimiter and an input value in an input argument associated with the given input attribute type. Moreover, the electronic device provides output messages using the predefined characteristic to convey output information associated with a set of output attribute types. A given output message includes one or more output-command characters specifying a given output attribute type in the set of output attribute types. In this way, the predefined characteristic can be repurposed to convey other attribute types.

Abstract: An environmental monitoring device that includes an acoustic sensor is described. During operation of the environmental monitoring device, the acoustic sensor provides acoustic data based on measurements of sound in an external environment that includes the environmental monitoring device. Based on the acoustic data and predefined characterization of the external environment, a control mechanism determines if an alarm device, which is separate from the environmental monitoring device, is activated. For example, the predefined characterization may include a location of the alarm device. This location may be specified by: an image of the external environment, a positioning system, a communication network, and/or an acoustic latency in the external environment. Alternatively, the predefined characterization may include an acoustic transfer function of the external environment proximate to the alarm device and the environmental monitoring device.

Abstract: An electronic device that obtains information about particles is described. This electronic device includes an imaging system that captures one or more images of the particles in a flowing fluid using an optical beam that is at an angle or approximately perpendicular to an average flow direction. In particular, the optical beam from an optical source is diffracted by an aperture, transmitted through a protective mechanism, and captured by an imaging sensor. The one or more images may include diffraction patterns of a subset of the particles deposited on the top surface. Moreover, the one or more images may be analyzed by the electronic device and/or remotely from the electronic device to determine the information about the particles, such as: types of particles, particle sizes, and/or a particle count. Note that the analysis may use signal processing to obtain a resolution that is less than a resolution of the one or more images.

Abstract: An environmental monitoring device that monitors the operation of a legacy electronic device is described. In particular, a sensor in the environmental monitoring device provides sensor data that represents an environmental condition in an external environment that includes the environmental monitoring device. This environmental condition is associated with the operation of the legacy electronic device in the external environment. The environmental monitoring device analyzes the sensor data and provides feedback about the operation of the legacy electronic device based on the analyzed sensor data. Moreover, the sensor provides the sensor data without or excluding communication and/or electrical coupling between the environmental monitoring device and the legacy electronic device. In this way, the environmental monitoring device facilitates monitoring, analysis and feedback of the sensor data without directly interacting with the legacy electronic device.

Abstract: An electronic device that monitors flow of a fluid in a vessel (such as a pipe) is described. This electronic device may be mounted on an exterior of the vessel using a mounting mechanism. For example, the mounting mechanism may be attached to the vessel using a clamp, and an impedance-matching material may provide mechanical coupling to the vessel. Moreover, during operation a sensor mechanism in the electronic device may measure flow of the fluid, and an integrated circuit in the electronic device may analyze the flow measurements. In particular, the sensor mechanism may measure flow using non-invasive techniques (e.g., using an ultrasound transducer, an acoustic sensor or a vibration sensor) without contact with the fluid. The sensor mechanism may also facilitate the analysis by determining an orientation of the sensor mechanism relative to a reference direction and/or a cross-sectional area of the flow.

Abstract: A mounting system for an electronic device is described. This mounting system includes a base that can be rigidly mounted on or underneath a wall. Moreover, the base can be remateably coupled to the electronic device. The remateable coupling may involve pins that are inserted into corresponding holes and rotated into a lock position. Alternatively, the remateable coupling may involve magnets that mechanically couple to each other so long as the electronic device and the base are within a predefined distance. The electronic device may receive power via the remateable coupling or via inductive charging. In addition, the electronic device may monitor a spatial parameter, such as: a location of the electronic device, a velocity of the electronic device and/or an acceleration of the electronic device. If this spatial parameter changes without the electronic device first receiving a security code, the electronic device provides an alert.
