Abstract: One or more embodiments of the invention introduces a novel recessed mounting system for ceiling components such as smoke detectors, improving their installation, aesthetic integration, and functionality. By recessing all electronics into the ceiling, the system achieves a streamlined appearance, leaving only the sensing element exposed. The system comprises three major components: the recessed housing, the sensor module, and the finish trim. The recessed housing seamlessly integrates with remodel and new construction projects, providing an unobtrusive look. The sensor module supports various sensor types, ensuring adaptability to different detection needs. The finish trim offers customization options, enabling field changes from round to square shapes and providing a selection of custom finishes to match architectural elements. This innovative system enhances the aesthetic appeal, smoke detection capabilities, and ease of installation of smoke detectors in residential, commercial settings.

Abstract: A method to navigate a vehicle utilizing a graphic projection display, includes monitoring a navigation status graphic representing a navigation intent displayed upon the graphic projection display, monitoring a user input indicated to a portion of the graphic projection display, initiating a user-defined navigation command based on the monitored navigation status graphic and the monitored user input, and operating the vehicle in accordance with the user-defined navigation command.

Abstract: A simulated vehicle tracking device is installed in a conspicuous location in a vehicle. The simulated vehicle tracking device outwardly resembles the appearance of a functional vehicle tracking device, including one or more indicator lights that turn on to simulate the operation of indicator lights on a functioning vehicle tracking device. An functional vehicle tracking device is installed in an inconspicuous location in the vehicle. A person inclined to disable vehicle tracking will remove or disable the simulated vehicle tracking device instead of the functional vehicle tracking device.

Abstract: A simulated vehicle tracking device is installed in a conspicuous location in a vehicle. The simulated vehicle tracking device outwardly resembles the appearance of a functional vehicle tracking device, including indicator lights which flash on and off in a pattern to simulate the operation of indicator lights on a functioning vehicle tracking device. An functional vehicle tracking device is installed in an inconspicuous location in the vehicle. A person inclined to disable vehicle tracking will remove or disable the simulated vehicle tracking device instead of the functional vehicle tracking device.

Abstract: An emitter includes a housing for attaching to a user and for receiving a control circuit having one or more CPUs, a memory coupled to the CPU, a sensing circuit coupled to the CPU for sensing a voltage supplied to the CPU, an emitting circuit coupled to the CPU for being actuated by the CPU to emit a signal out. The housing includes two switches coupled to the CPU, and two further switches for information entering purposes. The emitting circuit may send out the signal by actuating the switches. The functions of the emitter may be tested with the switches.

Abstract: A smoke detector test device comprising a stamped plate. Combustible elements are positioned and retained on the stamped plate which, when ignited smolder to provide smoke of sufficient volume to actuate a properly functioning smoke alarm without requiring or causing an open flame. The stamped plate has an aperture and inwardly projecting flanges that allow the plate to be effectively attached to a broom handle to give a user extended reach to place the device, and smoke generated thereby, in close proximity to the smoke detector. A method for forming the smoke detector test device is also disclosed.
