Abstract: The present invention is an alarm system that includes at least one base unit operable to detect sound levels and to transmit a signal to cause an alarm response, such as emission of media that may be the sound of one or more dog barks. The media may be emitted through one or more applicable broadcasting device, such as through a speaker, and may be the sound of one or more dog barks. The broadcasting device and base units may be configured to function collectively to create a realistic deterrent effect. Other alarm responses may be part of the system, such as electronic device warning messages, turning on a light, etc. The alarm responses and the general operation of the system may be set by a user, either through the base unit or by other remote input means (e.g., a fob unit or other electronic device).

Abstract: Sign 1 has frame 13 attaching to base 9 and supporting character plates 4. Casing 11 attaches to frame 13 and holds character plates 4 against frame 13. Light assembly 15 and base 9 backlight character plates 4. Backlight is diffusion chamber 17 sidelit by light assembly 15. Casing 11 hides access to the mount and is not easily removable. Light assembly 15 is externally powered and is activated by external messages and by low ambient light. An Emergency Alarm message causes flashing in one color and intermittent activation of sound. For non-emergency, alternate light mode is used with constant sound. Transmitter 1501 transmits messages for the sign 1. The transmitter 1501 learns emergency telephone numbers for dial detection on a telephone line, in addition to standard emergency telephone number. Emergency button 1507 can begin transmission of emergency alarm message. Transmitter 1501 may have other alarm inputs.

Abstract: A vacuum cleaner includes a housing adapted for movement on a subjacent surface and a nozzle defined in the housing, the nozzle having an opening. A brushroll tube, having first and second ends and a longitudinal axis, is rotatably mounted to the housing adjacent the nozzle opening. At least one cleaning element protrudes from the brushroll tube. A shaft is located in the brushroll tube and extends along the longitudinal axis thereof. A stator is rigidly mounted on the shaft. A cylinder surrounds the shaft and the stator and is spaced therefrom. The cylinder is rigidly connected to the brushroll tube. A permanent magnet rotor is fixedly mounted to an interior surface of the cylinder. The permanent magnet rotor overlies and is coaxial with the stator and is spaced therefrom. The rotor and stator form a motor for rotating the brushroll tube wherein the rotor is driven by changes in induced magnetic fields in the stator.
