20140060970 | LADDER CLIMBING APPARATUS - A ladder climbing apparatus is provided for use with a ladder having a plurality of rungs. The ladder climbing apparatus includes a frame, a prime mover mounted to the frame and a power supply electrically connected to the prime mover. A pulley system is mounted to the frame, and is mechanically connected to the prime mover. At least two drive belts are configured so that each of the drive belts pass around the pulley system, and the drive belts are connected to the prime mover by the pulley system. A plurality of gripper elements are attached to each of the drive belts. The ladder climbing apparatus is configured so that a portion of the plurality of gripper elements are in contact with at least four rungs of the ladder during an ascent or descent, so that weight is distributed over the at least four rungs of the ladder. | 03-06-2014 |

20150123782 | SUPERVISING ALARM NOTIFICATION DEVICES - In an example implementation, a system includes a control module, one or more electric circuits, each electric circuit including a resistor and one or more notification devices in parallel, and a supervisor module electrically coupled to the control module and the electric circuits. The supervisor module is configured to receive input electric power, the input electric power having a voltage in a range of 12 to 16 VDC, and apply, to each electric circuit, first electric power having a first polarity and a voltage of approximately 12 VDC. The supervisor module is also configured to determine, based on electric power returning from each electric circuit, an operational state of each respective electric circuit, and receive, from the control module, a trigger signal indicative of an alarm event. The supervisor module is also configured to, responsive to receiving the trigger signal, apply, to at least one electric circuit, second electric power having a second polarity opposite the first polarity and a voltage of approximately 12 VDC. | 05-07-2015 |
