Abstract: A system for monitoring integrity of a structure includes at least one sensor module and a gateway. The gateway receives data packets from the sensor module(s) and periodically pushes the data packets to an offsite system without receiving a request from the offsite system. Additional data packets may be transmitted on request. The system may include a solar power supply. The system may include a communication module to transmit data packets over a communications link. The communication module may have a dynamic IP address. The communication module may remain in a standby state until additional information is received from the gateway. A method for monitoring integrity of a structure includes determining a power failure and pushing a packet to the offsite system indicating the power failure. A method for monitoring integrity of a structure includes determining an event and transmitting a data packet corresponding to the event.

Abstract: An adjustable tilt construction for a toothbrush display rack. The rear wall of the rack is provided with one or more T slots, each slot receiving one of two parallel flanges of a respective leg, said leg being generally H shaped in transverse cross section over at least a portion of its length. One flange of each leg is shorter than the other, and is asymmetrically located with respect to it so as to yield two different distances from the ends of the shorter flange to respective ends of the longer flange. This leg configuration permits three different leg heights by inserting each leg into a respective slot in three different ways. In turn, this permits three different tilt angles for the display rack. Each leg has at least one end having biased edges which releasably frictionally fit into the T shaped slots on the rear wall of the rack. The leg and slot configuration may also be used on any member to provide height adjustment.

This leg configuration permits three different leg heights by inserting each leg into a respective slot in three different ways. In turn, this permits three different tilt angles for the display rack. The leg and slot configuration may also be used on a table to provide height adjustment, the legs and slots operating in the same manner as in the display rack.
