A footwear assembly structured to be collapsible comprising a sole including a front portion and a rear portion movably interconnected by an intermediate segment. An upper extends along at least a portion of the length of the sole, depending upon the style of the footwear, wherein the upper and the sole are preferably structured to define the sandal configuration which may vary in style. The intermediate portion includes sufficient flexibility to significantly reduce the size of the sandal by folding the sole into a stored orientation defined by the front and rear portions disposed in at least partially overlying relation to one another. A pouch-like container is dimensioned and configured to receive and maintain at least a pair of the sandals on the interior thereof, when in the stored orientation.

A lighting system including modules containing LEDs or other electroluminescent devices and loosely constrained magnetic structures at least partially contained within cavities in the module substrate that are connected to fixtures under magnetic force. The loosely constrained magnetic structures accommodate mechanical variations in the system and provide a method to connect modules mechanically, electrically and thermally to different fixtures or positions in fixtures without tools. The relatively short distance separating magnetic structures provides high connection forces with the use of relatively small magnets. Magnets and electrical contacts are not located directly between the LED subassembly and the fixture, which provides higher thermal conductivity pathways to remove heat from the LEDs. Biasing members may be used to increase thermal contact. Magnetic structures may, but are not required, to conduct electricity. Fixtures that attach to modules include rails, sockets, heat sinks and two-dimensional structures with recessed electrodes for improved electrical safety.

A diamond composite heat spreader having a low thermal mismatch stress can improve reliability and cost of diamond-based heat spreaders. A diamond composite heat spreader can have a thermally conductive base and a diamond film in thermal contact with the thermally conductive base. The diamond film and the thermally conductive base can have a residual thermal mismatch stress which is less than about 75% of a residual thermal mismatch stress which would result from forming the diamond film on the thermally conductive base using a high temperature deposition process at 700° C. The diamond film can be formed on the thermally conductive base using a low temperature vapor deposition process performed at a temperature from about 10° C to less than 700° C, and typically lower than about 450° C. The diamond films further have high thermal diffusivity and thermal conductivity which allow for dramatic improvements in heat transfer away from a heat source without the need for growing a thick diamond film. By providing a low temperature deposition of the diamond film, residual thermal mismatch stress can be significantly reduced, while allowing for use of well known heat spreaders such as standard copper heat spreaders and associated technologies.

A wireless localization technology using efficient multilateration in a wireless sensor network is disclosed. After calculating estimated distances from each of at least three reference nodes to a blind node using received signal strength of wireless signals that the at least three reference nodes received from the blind node, the estimated location of the blind node is obtained through multilateration using the calculated estimated distances. To correct error in the estimated location, the estimated distances are used, and the error correction direction and error correction distance for the estimated location are calculated by applying a largest weight to the reference node closest to the estimated location. The error of the estimated location is corrected by move the estimated location of the blind node by the calculated error correction direction and error correction distance. Calculation for the error correction is very simple and fast.

The power controller increases the duty cycle of the drive signal as the first voltage decreases in order to maintain the second voltage at a substantially constant average value per unit time. By providing the above arrangement, the motor can be supplied with a constant voltage throughout the available run time of the battery. When forming part of a cleaning appliance having a motor, the above arrangement allows the motor to operate at a substantially constant speed throughout the run time of the battery.

A bleed valve for bleeding air from a compressed air chamber at start-up of a gas turbine engine is self-actuated. The bleed valve moves between open and closed positions based on the pressure within a compressed air chamber. In this manner, the bleed valve is driven to an open position at low pressure conditions and to a closed position once the pressure within the compressor chamber becomes higher and closer to operating pressures. In this manner, a relatively inexpensive and simple bleed valve can be utilized to provide the start-up bleed valve function.
