Abstract: A method includes receiving, from a subscriber device, a request including virtual region characteristics and an occupancy threshold, and determining, using image data captured by a camera and the virtual region characteristics, a virtual region corresponding to a portion of a physical region within a field of view of the camera. The virtual region is smaller than the physical region. The method also includes determining, using the image data, an occupancy of the virtual region and determining that the occupancy of the virtual region satisfies the occupancy threshold. In response to determining that the occupancy of the virtual region satisfies the occupancy threshold, the method also includes generating a notification to the subscriber device.

Abstract: A facility for operating a first node in a mesh network having other nodes is described. The first node directly receives signals each encoding an identifier of one of the other nodes, at least a portion of the signals also encoding an indication that the node having the identifier has appointed itself a routing node. The facility determines a first value equal to the number of unique node identifiers encoded in signals received during a first period of time, and a second value equal to the number of unique node identifiers encoded by signals received during the first period of time that also encode the indication. The facility determines a routing score for the first node based at least upon the first value and the second value that reflects the first node's suitability as a routing node in the mesh network.

Abstract: In a first participant in a network—such as an ad hoc wireless network—a facility performs peer regulation of the network. The facility monitors behavior of a second participant in the network that has appointed itself a routing participant for the network. Among the monitored behavior, the facility identifies behavior of the second participant that is inconsistent with its routing participant status. In response to this identifying, the facility sends a message to participants of the network including a third participant indicating that the second participant is no longer a routing participant.

Abstract: A facility that controls participants in an ad hoc peer wireless network to use transmission power level settings and routing paths that best serve individual participants in the network and the network as a whole is described. Variously, the facility modulates transmission power levels to extend participant battery life and reduce the likelihood of radio interference in the network; establishes routing paths that contribute to the effectiveness and continuing operation of the network; and monitors for and responds to the occurrence of interference in the network's communications.

Abstract: Example implementations may relate to methods and systems for detecting an event in a physical region within a physical space. Accordingly, a computing system may receive from a subscriber device an indication of a virtual region within a virtual representation of the physical space such that the virtual region corresponds to the physical region. The system may also receive from the subscriber a trigger condition associated with the virtual region, where the trigger condition corresponds to a particular physical change in the physical region. The system may also receive sensor data from sensors in the physical space and a portion of the sensor data may be associated with the physical region. Based on the sensor data, the system may detect an event in the physical region that satisfies the trigger condition and may responsively provide to the subscriber a notification that indicates that the trigger condition has been satisfied.

Abstract: The present invention relates generally to methods of treatment of Alzheimer's Disease or Mild Cognitive Impairment which are adapted to avoid negative interactions between combinations of therapeutics. In particular there are disclosed such methods of treatment in which the order of therapeutics is actively controlled to mitigate homeostatic downregulation prior to administration of active, for example disease modifying, therapeutic agents. In certain embodiments therapy with symptomatic treatments (such as modifiers of the activity of acetylcholine or glutamate neurotransmitters) may subsequently be combined with the disease modifying or other active treatment. The invention also applies the findings in relation to homeostatic downregulation to novel methods of clinical trial design.
