Title: Electronic devices
Inventor: Piotr LEWANDOWSKI
IPC: H02J9/00
Filed: 2019-06-06
Abstract: An electronic device 100 for providing a notification, for example a smart doorbell, alarm, smoke detector, or motion sensor, has a processing circuit 104, a power supply circuit 120, and an activation circuit 108. In response to an activation event, such as the doorbell being pushed, the activation circuit 108 triggers the supply of power from the power supply circuit 120 to the processing circuit 104. In response to receiving power following an activation event, the processing circuit 104 provides a control signal 121 to maintain the supply of power from the power supply circuit 120 to the processing circuit 104, and whilst receiving power from the power supply circuit 120, provides a notification, such as a notification to a mobile phone belonging to a remote user, in response to the activation event. Once it is determined that power is no longer required to be supplied from the power supply circuit 120 to the processing circuit 104 in response to the activation event, the processing circuit 104 provides a control signal 121 to stop the supply of power from the power supply circuit 120 to the processing circuit 104. The device consumes no power at times when the notification is not being provided.

IPC: G08B29/14
Filed: 2020-03-05
Abstract: Hazard detector testing system 100 comprises sensor 130, stimulus generator 150, and controller 110. The sensor detects both EM-radiation produced by a hazard detector and ambient EM-radiation. The stimulus generator produces a test stimulus such as heat or simulated smoke to activate an alarm state of the hazard detector. The controller determines whether the hazard detector has entered an alarm state based on the EM-radiation detected by the sensing arrangement. The electromagnetic radiation may be visible light. The hazard detector may produce EM-radiation periodically and the testing system may determine that the hazard detector is in an alarm state when it produces EM-radiation continuously or at a different periodicity. The system may feature a proximity sensor and/or a time-of-flight sensor. Further aspects include: testing a hazard detector based on a detected signal from the detector and a sensed distance between the detector and a testing system; testing a hazard detector based on an alarm state and a detected stability of the detector; and calibrating a hazard detector testing system.
