Title: Wireless local area network (wlan) method and system for presence detection and location finding
Inventor: AMSALEM REUVEN
IPC: G01S5/14
Filed: 2006-05-09
Abstract: A wireless local area network (WLAN) method and system for presence detection provide a low-cost and WLAN-compatible means for detecting the presence of an asset without requiring full location-finding support within a WLAN  environment. The presence of a transmitter is detected by examining the signal strength of a presence signal. The presence signal is WLAN-compatible, but does not require association of the transmitter with the WLAN and does not require a response from the WLAN. The presence signal may be transmitted on multiple WLAN channels for presence detection by multiple WLAN APs. The presence signals transmissions may be periodic or may be stimulated by a stimulus from the WLAN or external device that may or may not be coupled to the WLAN. Location finding can also be performed in combination with the signal strength presence detection.

Abstract: A defect in a horizontal or vertical seam at the edge of a roof membrane is detected by applying a DC voltage between the roof deck a probe in the form of a flexible wetted sponge and wiping the sponge probe over the seams. The current to the probe is detected and indicated to the operator so that the operator may determine a maximum current at the defect. The receiver provides an audible signal emitter to the operator and includes a calibration circuit arranged to automatically maintain, despite changes in voltage applied between the roof deck and the peripheral conductor, a "0" set calibration point so as to indicate at the calibration point when zero difference in voltage is detected. Conductors can be applied to the membrane to define an area to be tested within the conductors.

Filed: 2001-12-03
Abstract: A reciprocating pump includes a drive section and a pump selection. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied during operation. A permanent magnet structure of the drive section creates a magnetic flux field which interacts with an electromagnetic field produced during application of the control signals to the coil. Depending upon the polarity of the control signals applied to the coil, the coil is driven in one of two directions of movement. A drive member transfers movement of the coil to a pump element which reciprocates with the coil to draw fluid into a pump chamber and expel the fluid during each pump cycle. The pump is particularly well suited to cyclic pumping applications, such as fuel injection and emissions control systems for internal combustion engines.
