There is disclosed apparatus, method and system for mechanically joining abutting construction elements having a first split tongue located at one end of the connector and a second split tongue located at the other end of the connector. The first and second split tongues are adapted to be inserted into and locked onto grooves in abutting construction elements for holding the adjacent construction elements in abutting relationship. In an embodiment the grooves in said construction elements are formed into auxiliary groove containing members adapted to be integrated into an edge or face surface of the construction elements.

An airbag apparatus for protecting an occupant of a vehicle comprises an inflatable chamber formed by at least one fabric panel and configured to be filled with an inflation gas and deploy into position to protect the occupant; and a tether connected to the panel to restrain deployment of the airbag. During the initial deployment sequence of the airbag, the tether fully extends to a first length. The tether unfolds in order to fully extend to a second length when a sufficient force is applied to the tether by the deploying airbag.

A semiconductor flash EPROM/EEPROM device which includes a command port for receiving instruction on a data line and providing control signals to a memory for providing program and erase functions, a method to program and erase the memory. A program sequence is comprised of setting up a program command during a first write cycle, preforming a second write cycle to load address to address register and data to to a data register, programming during a program cycle and writing a program verify command during a third write cycle to verify the programmed data during a read cycle. An erase sequence is comprised of writing a setup erase command during a first write cycle, an erase command during a second write cycle providing the erasure during an erase cycle, writing the erase verify command during a third write cycle which also addresses the address of the memory and providing erase verification during a read cycle. Both the erase and program cycles provide for measured incremental erasing and programming.

Systems and methods according to these exemplary embodiments provide for methods and systems related to optical current sensors used to monitor standby power transformers, specifically fiber optical current and voltage sensors and, more particularly, to applications involving filters for use in such sensors, such as frequency tracking comb filters. According to one embodiment, a method for monitoring a connection condition of a stand by power transformer includes the steps of measuring a current flowing through a high voltage side of the standby power transformer using at least one optical current sensor disposed proximate to a current flow path of the high voltage side, using a comb filter to filter the measured current, determining whether the filtered, measured current is less than a predetermined threshold value; and generating an alarm indication that the high voltage side of the standby power transformer is unconnected.

A method of mechanically joining wood panels side edge to side edge by providing a panel with a groove between a top and bottom surfaces of the panel having two holding ramps with an angle of between 25 degrees and 60 degrees relative to the groove insertion axis which is parallel to the top surface; providing a connector adapted to mate with the groove of the panel having two right-side sub-tongues extending from right side and two left-side sub-tongues extending from the left side of a rectangular base support, and outward extending distal catches on the sub-tongues in a direction substantially normal to the groove insertion axis; and inserting the sub-tongues with distal catches into the groove along the groove insertion axis allowing the distal catches on the two right-side or two left-side sub-tongues to touch the two holding ramps causing the sub-tongues to flex.
摘要:
A connector for mechanically joining abutting construction elements each having a groove therein, comprising a support, at least one split tongue extending from the support, the split tongue including flexible sub-tongues having angled catches for engaging steps located in the groove. During insertion the sub-tongues are flexed toward each other and remain in a partially restored configuration. This, combined with the angled catches, reduces the space between the abutting construction elements.

An emergency respondence warning system for warning of the approach of emergency vehicles at roadway intersections. The warning system comprises a transmitter mountable to an emergency vehicle and a receiver situated near the roadway intersection. As the emergency vehicle approaches the intersection, the transmitter sends signals to the receiver, which are processed by the receiver when the vehicle is within a predetermined distance. The receiver activates a distinct visual warning signal alerting nearby drivers and pedestrians of the approach of an emergency vehicle. The emergency respondence warning system also warns of the approach of multiple emergency vehicles. When the receiver determines that two emergency vehicles are approaching the intersection, it activates the warning element but triggers a dedicated visual signal indicating the approach of multiple vehicles.
