Abstract
A detector includes a housing having a window. A detection engine is configured to detect an event external to the housing. A battery is connected to the detection engine and configured to supply power thereto. A solar cell is configured to generate electricity when exposed to a light received through the window. The solar cell is arranged in the housing and electrically connected to the battery.
Claims13
A detector comprising:
- a housing having a window;
- a detection engine configured to detect an event external to the housing;
- a battery connected to the detection engine and configured to supply power thereto;
- a solar cell configured to generate electricity when exposed to a light received through the window, the solar cell arranged in the housing and electrically connected to the battery;
- a mirror separate from the window and arranged within the housing, the mirror oriented to direct the light from the window onto the solar cell;
- and
- a controller is in communication with the battery and the solar cell, the controller configured to generate an ON command in response to a low battery condition associated with the battery and/or a low-light condition detected by the solar cell.

An alarm system comprising:
- a light source;
- a light switch in communication with the light source and configured to increase light from the source in response to an ON command;
- and
- a detector including:
- a housing having a window;
- a detection engine configured to detect an event external to the housing, the detection engine in communication with the light switch, wherein the detection engine is configured to send the ON command to the light switch in response to a low battery condition associated with the battery and/or a low-light condition detected by the solar cell;
- a battery connected to the detection engine and configured to supply power thereto;
- a solar cell configured to generate electricity when exposed to a light received through the window, the solar cell arranged in the housing and electrically connected to the battery;
- and
- a mirror separate from the window and arranged within the housing, the mirror oriented to direct the light from the window onto the solar cell.
7 more elements
A method of operating an alarm detector comprising:
- powering a detection engine with a rechargeable battery, wherein the detection engine is configured to detect an event corresponding to at least one of a glass breakage, a vibration, a motion and/or a noise;
- recharging the battery with a solar cell, wherein the recharging step includes directing a light onto a mirror separate from a window receiving the light, and reflecting the light with the mirror onto the solar cell;
- and
- turning on a light source with the detection engine in response to a low battery condition associated with the battery and a low-light condition detected by the solar cell.
