Patent number: 12113583Abstract: Improved electrical testing of N-port beamforming devices is provided. For testing, an N:1 electrical network is connected to the N ports of the device under test to provide a single test port. This mode of testing can be used to determine parameters of interest (e.g., far field radiation patterns etc.) of the device under test more rapidly than with antenna range testing or with characterization of each port of the device under test. The N:1 electrical network can be passive or active. The N:1 electrical network can be integrated in a probe head to provide probe array testing of beamforming devices. Alternatively, the N:1 electrical network can be integrated with the device under test to provide onboard testing capability.Type: GrantFiled: January 7, 2021Date of Patent: October 8, 2024Assignee: FormFactor, Inc.Inventors: Dennis Rosenauer, Roger Hayward, Roy Swart

In a preferred embodiment of the invention, the arrangement comprises an antenna member mounted to the circuit board. The antenna member includes a first surface, second surface and a third surface. The third surface adjoins the first and second surfaces. The first, second and third surfaces define a cavity within which is disposed dielectric material. At least one conductive connector comprising first and second ends is in communication with the antenna member first surface. An amplifier is in communication with each conductive connector second end.Type: GrantFiled: September 14, 2001Date of Patent: April 13, 2004Assignee: Stata Labs, LLCInventors: Roger Hayward, Richard Fuller, John Glissman, Noel Marshall

Patent number: 6704650Abstract: A method of determining the distance traveled during an event by a mobile GPS receiver. The event comprises epochs. The method comprises receiving pseudorange data comprised of one of pseudorange differences or range rates. Each pseudorange difference, in turn, comprises a difference between a first pseudorange and a second pseudorange. The first pseudorange comprises the pseudorange between the receiver and a GPS satellite at a first epoch. The second pseudorange comprises the pseudorange between the receiver and the GPS satellite at a second epoch. The range rates comprise a range rate measurement taken by the receiver of the GPS satellite from the first epoch to the second epoch. Line-of-sight data comprised of at least one normalized vector between the receiver and the GPS satellite is then determined. Based on the pseudorange and line-of-sight data, incremental distance data is then determined. A sum over the event of the incremental distance data is then determined.Type: GrantFiled: May 31, 2001Date of Patent: March 9, 2004Assignee: SkyNetix, LLCInventors: Richard A. Fuller, Roger Hayward, Jock Christie

Patent number: 6606072Abstract: A GPS receiver includes a slot antenna having first and second surfaces. The second surface includes a semi-circular portion. The first and second surfaces define a slot within which is disposed dielectric material. The slot antenna is optimized for receiving GPS signals when in proximity to a human body. The relatively compact size of the slot antenna allows for the incorporation of the antenna into a small device that can be worn on or carried in close proximity to the body of a user. This type of antenna is not as sensitive to gain variations when in the proximity of a human body because the design has a wider aperture and thus operates better near the body. Further, this type of antenna is virtually omni-directional, i.e., it is not problematically sensitive to the location of the GPS signal source. Moreover, the design is such that the antenna arrangement can be oriented within a device in a way that maximizes the number of GPS satellites tracked.Type: GrantFiled: July 6, 2001Date of Patent: August 12, 2003Assignee: Stata Labs, LLCInventors: Roger Hayward, Richard Fuller, John Glissman, Noel Marshall

Patent number: 6552681Abstract: A method of using altitude information to arrive at a more accurate GPS position. A 3D GPS position is used as an initial estimate. The latitude and longitude of the initial estimate are used to retrieve an altitude from a database. This altitude is used to calculate a 2D GPS position. The 2D GPS position is then used to retrieve another altitude from the database, and the calculate-retrieve process is continued until the calculation converges.Type: GrantFiled: October 2, 2001Date of Patent: April 22, 2003Assignee: SkyNetix, LLCInventors: Roger Hayward, Richard Fuller

Patent number: 6531981Abstract: A system and method is disclosed for corresponding data associated with primary correction of at least one first measurement of a GPS satellite characteristic to a second measurement of the GPS satellite characteristic taken at a mobile receiver. In a preferred embodiment of the invention, a first processor is coupled to at least one wide-area GPS corrections receiver and at least one local-area GPS corrections receiver. The wide-area and local-area receivers operate to determine the first measurement and secondary data associated with correction of the determined first measurement. In operation, an estimate of the location of the mobile receiver is determined by the first processor. The availability to the mobile receiver of the secondary correction data from the wide-area and local-area GPS corrections receivers is determined, preferably based on the location estimate. From the secondary correction data, primary data representing the primary correction is determined by the first processor.Type: GrantFiled: April 30, 2001Date of Patent: March 11, 2003Assignee: SkyNetix, LLCInventors: Richard A. Fuller, Roger Hayward, Jock Christie
