摘要:
A system and method provides access to antennas of an electronic article surveillance system via WiFi and the Internet. Each antenna of the EAS system has a WiFi chip associated with its controls and the WiFi chip relays the antennas operating parameters as well as its reading of electromagnetic noise in its environment to the Internet. A remote technician can review the information provided by the antennas of the EAS system and optimize their operation with each other and their environments. In some embodiments, remote software can optimize the operation of the EAS system antennas. In some embodiments, the WiFi chip is an aftermarket addition.

A method includes: collecting data about a first event at a first physical space using a first electronic monitoring device that is physically located at the first physical space, enabling the collected data to be displayed at a computer-based user interface device (e.g., at a user's a smartphone that may be remotely located relative to the first electronic monitoring device), enabling the user to describe, using the computer-based user interface device, the first event represented by the collected data, and storing, in a computer-based memory, a logical association between the user's description of the first event and one or more characteristics of the collected data.
摘要:
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.
摘要:
A particular smart hazard detector may itself function as a guide during a process of installation of the same at an installation location. Additionally, the installation location of the particular smart hazard detector may play a central role in how various settings of the smart hazard detector are defined and adjusted over time.

摘要:
Ambient amount of a hazardous condition may be monitored. A mode may be set to a state indicative of the hazardous condition being present in the ambient environment. It may then be determined that the amount of the hazard in the ambient environment has dropped below an alarm criterion. A time period may then be tracked during which the amount of the hazardous condition present in the ambient environment of the hazard detector has remained below the alarm criterion. It may be determined that the time period has reached at least a threshold duration, during such time period the amount of the hazardous condition present in the ambient environment of the hazard detector having remained below the alarm criterion. An indication of the hazardous condition easing may be output in response to the time period being at least the threshold duration.
摘要:
Methods and apparatus for smoke detection are disclosed. In one embodiment, a smoke detector uses linear discriminant analysis (LDA) to determine whether observed conditions indicate that an alarm is warranted.
摘要:
There is provided a fall detection and/or prevention system, comprising one or more sensors for detecting characteristics of movement of a user of the fall detection and/or prevention system and for generating corresponding signals; processing means for analyzing the signals from the one or more sensors using a fall detection algorithm to determine if a fall has taken place or is likely to take place; wherein the processing means is further adapted to update said fall detection algorithm based on the result of the analysis of the signals and an indication whether a fall has actually taken place from the user or a third party.

Ambient amount of a hazardous condition may be monitored. A mode may be set to a state indicative of the hazardous condition being present in the ambient environment. It may then be determined that the amount of the hazard in the ambient environment has dropped below a threshold hazardous condition level. A time period may then be tracked during which the amount of the hazardous condition present in the ambient environment of the hazard detector has remained below the threshold hazardous condition level. It may be determined that the time period has reached at least a threshold duration, during such time period the amount of the hazardous condition present in the ambient environment of the hazard detector having remained below the threshold hazardous condition level. An indication of the hazardous condition easing may be output in response to the time period being at least the threshold duration.
摘要:
A method and apparatus that includes the steps of receiving a PIR signal and video signal from a passive infrared (PIR) sensor having a PIR detector and camera, displaying a video image from the camera on a display, overlaying a range of the PIR detector and a magnitude of the PIR signal on the displayed video image, displaying a video image of a person walk testing the PIR sensor on the display in conjunction with the overlaid range and a magnitude of the PIR signal provided by the PIR detector and receiving an adjustment from the user of a detection threshold value of the PIR sensor based on the displayed image.
