Abstract: A three-way switch associated with an entry point barrier may provide a security system with information regarding a position of the entry point barrier as it moves along a path of travel. As the entry point barrier moves, the three-way switch may come into proximity with an external object, and the three-way switch may indicate to the security system that a circuit associated with the three-way switch has been closed. The security system may determine that the entry point barrier is in a given position, and one or more security system policies associated with the given position may be activated.

Abstract: An automated shading system defines an environmental state as a discrete variable representing a history of values of a second discrete variable representing the ambient environment. The system executes a state-specific automated shading command upon occurrence of each state. Prior to usage, each automated shading command is initialized to one of two types of command, as a function of the corresponding state: an “adjust shading” command that causes an automatic adjustment to a predetermined shading setting, or a “do not adjust” command that causes no shading adjustment. The system also enables a user to directly adjust the shading to a selected setting via deliberate shading commands. After each deliberate shading adjustment, the system updates the automated shading command associated with the current state to an “adjust shading” command that, upon subsequent occurrence of the same state, will cause an automatic adjustment to the same selected setting.

Abstract: An automatic door system capable of distinguishing between a door closing action for when an object leaves a prescribed area, which results from a “signal discontinuation due to the exit of an object”, and a door closing action for when an object remains stationary within the area for a certain period of time, which results from a “forced signal discontinuation in the presence of a stationary object”. Regarding the latter case, the automatic door system protects a person who stops in the area by setting the door to close at a low speed and/or issuing a vocal warning. The door closing action of the automatic door system can thereby reduce the risk of hitting the person with the door.

Abstract: In a first aspect, the present invention is a method, apparatus, and system for detecting a change in position of a door or a window in an alarm system with a singular housing having a magnetometer for monitoring the magnetic field of the earth, and a microprocessor for detecting a change in the position of the singular housing with respect to the magnetic field of the earth.
