Abstract: Systems and techniques are provided for guided installation feedback for an opening sensor. Detected magnetic field strengths of a magnetic field created by a magnet of an opening sensor as detected by a magnetometer sensor of the opening sensor may be received over a time period. It may be determined that there has been a change in the strength of the magnetic field created by the magnet as detected by the magnetometer sensor based on the received detected magnetic field strengths. Accelerometer data from an accelerometer disposed in the magnetometer sensor may be received. It may be determined from the accelerometer data that the magnetometer sensor was not moving and positive feedback may be provided to an installer of the opening sensor, or it may be determined from the accelerometer data that the magnetometer sensor was moving and negative feedback may be provided to the installer of the opening sensor.

Abstract: A magnet and magnetometer may be integrated into a smart home environment and allow it to be placed into an away mode of operation despite an entry point being semi-open. The disclosed implementations can detect a magnetic field strength and determine, based on the detected field strength, an approximate distance that a moveable partition is open. In some configurations, the presence of a second magnetic source can be detected. A notice may be generated based on one or more signals received from the magnetometer. The notice may be sent to a controller, a remote system, a remote device, and/or a client device as disclosed herein.

Abstract: Systems and methods for using state machines to manage alarming states and pre-alarming states of a hazard detection system are described herein. The state machines can include one or more sensor state machines that can control the alarming states and one or more system state machines that can control the pre-alarming states. Each state machine can transition among any one of its states based on raw sensor data values, filtered sensor data values, and transition conditions. Filters may be used to transform raw sensor values into filtered values that can be used by one or more state machines. Such filters may improve accuracy of data interpretation by filtering out readings that may distort data interpretation or cause false positives. For example, smoke sensor readings may be filtered by a smoke alarm filter to mitigate presence of steam.

Abstract: In accordance with some embodiments, the way in which the fuses are sensed and, particularly, their order may be made more random so that it is much more difficult to simply exercise the device and determine all the values of the storage elements within the fuse array. One result is a more secure storage device.

Abstract: A sensor package is disclosed that includes, a compass, an accelerometer, and an electromagnetic flux tag based open/close sensor. The compass may be activated by a microcontroller in response to an indication of movement detected by an accelerometer. The compass's data may be utilized to determine an orientation for the object such as a door on which the sensor package is situated. The orientation data may indicate that the door is ajar and/or that a second magnetic field is present, suggesting tampering. A notice may be dispatched to a controller for the home security system, a client device, a remote system, etc.

Abstract: A fuel line connector assembly that includes first and second connectors. The first connector includes a ramp having an inner core and an outer skin surrounding at least a part of the inner core. The inner core extends through the ramp at a location adjacent a radially extending retaining surface for at least a portion of the radial extent of the retaining surface. The second connector has a hook wherein, when the first and second connectors are brought together and secured to each other, the hook inhibits separation of the first and second connectors by bearing again the retaining surface. The first connector is made by coinjection molding a connector body having the outer skin and inner core with the inner core extending through the ramp to a sacrificial portion, and then severing the sacrificial portion from the ramp leaving the inner core exposed at an apex of the ramp.
