Abstract: An azimuth drive for a radar array comprises an electromagnetic track mounted to a wheel on which the radar array is mounted; and a magnetized carriage assembly operatively coupled to the electromagnetic track and capable of moving along the track in a tangential direction in response to electromagnetic force from select portions of the track to thereby relocate the center of mass of the wheel on which the radar array is mounted, wherein a moment produced from relocation of the center of mass is used to rotate the wheel.

Abstract: A pixel structure and an edge-emitter field-emission display device having a first substrate or backplate including a cathode disposed thereon and a second substrate or faceplate including an anode disposed thereon, wherein the anode on the second substrate or faceplate has a light emitting film. The cathode may define a first bus of an X-Y bus array and the anode may define a second bus of the X-Y bus array. Alternatively, the first substrate may further include a control gate disposed thereon, wherein the cathode defines a first bus of an X-Y bus array and the control gate defines a second bus of the X-Y bus array.

Abstract: An ultra high temperature hermetically protected transducer includes a sensor chip having an active area upon which is deposited piezoresistive sensing elements. The elements are located on the top surface of the silicon wafer chip and have leads and terminals extending from the active area of the chip. The active area is surrounded with an extending rim or frame. The active area is coated with an oxide layer which passivates the piezoresistive sensing network. The chip is then attached to a glass pedestal, which is larger in size than the sensor chip. The glass pedestal has a through hole or aperture at each corner. The entire composite structure is then mounted onto a high temperature header with the metallized regions of the header being exposed to the holes in the glass pedestal; a high temperature lead is then bonded directly to the metallized contact area of the sensor chip at one end. The leads are of sufficient length to extend into the through holes in the glass pedestal.

Abstract: A method for reducing the interference between a source transmitting pulses and equipments having nominal bandwidths which are outside the nominal bandwidth of the transmitted pulses, but which respond to sideband energy of the pulses. Phase perturbations are applied to the edges of the pulses produced by the source, to thereby tend to null the sideband energy lying in the nominal bandwidth of the equipments occupying the adjacent nominal bandwidths.

Abstract: A weighing scale having a display and processor for determining and identifying the optimal position coordinates for a load placed on the weighing scale includes a platform and a plurality of support assemblies, each containing a load cell for receiving the weight of the load. The display includes a meter or other graphical display that identifies position coordinates along with the determined numerical weight. Individual outputs from each of the plurality (e.g. 4) of load cells are received by a processor configured to compute x,y vector coordinates associated with the weight parameters for each load cell. The determined current or actual load position relative to an optimal position is calculated and displayed along with the weight.

Abstract: A mechanical weighing scale having mechanical parts driving a pointer rotating around a fixed disc or dial having slots or holes formed therein. The mechanical pointer operates to provide an analog display of one's weight to the user. An optical sensor system is responsive to the mechanical motion of the mechanically-rotating pointer as it passes over each of the holes or slots for determining a number of counts associated with the mechanical motion of the rotating pointer and translating the counts to a corresponding weight value for display onto a digital display.

Abstract: A method and system for preventing a computer worm from unauthorized use of data indicative of at least one e-mail address stored in a data base is presented. The method comprises the steps of encrypting said data, receiving at least one e-mail message by accessing an e-mail server, decrypting said selected ones of said data to provide access thereto, and addressing at least one e-mail message using said decrypted data. The method further includes the step of re-encrypting the selected decrypted data. In one aspect of the invention, the method of encrypting the data comprises the steps of obtaining a key value, selecting each of the at least one e-mail address, encrypting the selected e-mail address using the key value; and storing said encrypted e-mail in the data base.

Abstract: A reconfigurable array including: a plurality of imaging layer including an array of software addressable pixels; a conductive/non-conductive layer being positioned with respect to corresponding ones of the pixels such that addressing them causes corresponding portions of the conductive/non-conductive layer to be conductive; a radiator layer being positioned with respect to corresponding ones of the pixels such that addressing them defines at least one radiator array; a switching and summing layer positioned with respect to corresponding ones of the pixels such that the addressing them causes corresponding portions of switching and summing layer to switch and sum the signals; and, a plurality of inputs coupled to the imaging layers and being under software control to selectively activate the pixels.

Abstract: A sensor is described, which basically consists of a leadless high sensitivity differential transducer chip which responds to both static and dynamic pressure. Located on the transducer are two sensors. One sensor has a thicker diaphragm and responds to both static and dynamic pressure to produce an output indicative of essentially static pressure, the static pressure being of a much higher magnitude than dynamic pressure. The other sensor has a thinner diaphragm and has one side or surface responsive to both static and dynamic pressure. The other side of the differential sensor or transducer structure has a long serpentine reference tube coupled to the underneath of the diaphragm. The tube only allows static pressure to be applied on the underside of the diaphragm and because of the natural resonance frequency of the tube, the dynamic pressure is suppressed and does not, in any manner, interface with the sensor or transducer having a thinned diaphragm.

Abstract: The present invention relates to a synchronizing ring comprising a tapered internal bore provided with sharp axial teeth. The synchronizing ring comprises axial grooves distributed on the tapered internal bore, each groove extending over a surface corresponding to at least three consecutive axial teeth, two successive grooves being separated by at least ten axial teeth.

Abstract: A multi-load beam transducer includes a fixed member, a movable member, and a plurality of load beams positioned between the members, each beam separated by a given distance normal from each other and positioned about a longitudinal axis between the members. The plurality of load beams are responsive to forces exerted on the members. The transducer further includes a plurality of resistors positioned on selected ones of the plurality of load beams. The resistors have a resistance value which varies with an applied force with the plurality of resistors electrically connected and operable to determine the value of the applied forces.

Abstract: A system and method for securely exchanging plurality of information items used to generate a plurality of encryption keys used in a public key-and-private key system. In accordance with the principles of the invention, elements of exchanged information items, such as public key and synchronizing indictors are encrypted before the exchange. The information item element is encrypted using an encryption key determined from information items that were previously exchanged. The encryption of information items used to determine subsequent encryption keys provides additional security to the encryption key used in the transmission of informational data as the encrypted elements of the information item must be decrypted before the data message encryption key can be decrypted. The process of exchanging encrypted information items can be repeated until an agreed upon number of encrypting keys is determined.
