摘要:
A door blocker includes a wireless transmitter coupled to a forced entry sensor. In response to sensing a stressed blocking element the transmitter emits an alarm indicator. At the same time, the blocking element continues to limit movement of the door relative to the frame to exclude an intruder.

A key fob with a housing into which a deadbolt key is mounted such that the shank protrudes therefrom, enabling a user to turn the housing and cause the key to lock or unlock the door. Within the keyfob are a pair of switches or other sensing means configured to close on either the turning of the housing in a first (clockwise) direction or a second (counterclockwise) direction. Based on the direction the housing is turned, either a first coded signal or a second coded signal is transmitted to a control panel. The control panel will then either arm or disarm the security system based on how it has been programmed during installation. This enables the user to easily arm the system when the door is being locked and disarm the system when the door is being unlocked without requiring a separate action on the part of the user.
摘要:
A space safety apparatus monitoring a volume of space encompassing a field of view (FOV) for detecting an intrusion including a gas or vapor, and includes a micro-electro-mechanical system (MEMS) having mirror elements in a mirror array for reflecting infra-red (IR) energy beam collected from the FOV and an IR energy detector for detecting the IR energy reflected by the MEMS array and converting the IR energy to an output signal. A processor adjusts an angle of an element of the MEMS mirror array by varying a control signal, or by switching from one to another focusing element. The method includes detection in a volume of space by positioning a MEMS mirror array to reflect IR signal with respect to active elements of an IR detector; and collecting IR energy from an ith portion of the FOV.

A security system is provided. The security system includes a control panel located within a secured space, a plurality of sensors coupled to the control panel that detect security events within the secured space, a user interface within the secured area coupled to the control panel, a camera located in the user interface that collects video images in the secured space surrounding the user interface upon activation of one of the plurality of sensors, a sound transducer located in the user interface, a programmed processor within one of the user interface and the control panel that supports VoIP calls between a called or calling party and the user interface and a control button on the user interface that activates a VoIP connection with a called or calling party through the user interface and control panel.

A MEM's reed switch array is provided having a first switch having a sensitivity causing the first switch to open or close due to a magnetic flux, and a second switch of lesser sensitivity than the first switch causing the second switch to open or close due to a magnetic flux. The first switch can be parallel to the second switch, or the first switch can be proximate to the second switch so that a center line of the first switch is coaxial to a center line of the second switch. Further, a security device for residential and/or commercial use is provided, having a magnet housing having a magnet, a switch housing having a MEM's reed switch array with a first switch and a second switch, and a gap between the magnet housing and the switch housing.
摘要:
A filter component for a smoking article includes an upstream segment of filter material, a downstream segment of filter material in a spaced apart relation to the upstream segment of filter material so as to define a cavity therebetween, and a flavor bead disposed in the cavity. The flavor bead has an outer diameter, which is at least 75% of the spaced apart relation of the upstream segment of filter material and the downstream segment of filter material. The outer diameter of the flavor bead does not exceed an outer diameter of either the upstream or downstream segments of filter material.

摘要:
A tamper detection switch is primarily for use in an enclosure of a security system component. The enclosure has a base and a cover that may be repositioned relative to the base. One of the cover and the base holds a conductive magnetic element free to translate within a predetermined range generally perpendicular to the respective cover or base. The other of the cover and the base holds at least two ferrous metal contacts of an open tamper circuit in proximity of a conductive magnetic element. In the closed position the conductive magnetic element bridges the ferrous contacts and closes the tamper circuit. Attempts to tamper with the enclosure separate the ferrous contacts from the conductive magnetic element, opening the tamper circuit and signaling a possible attack.
