Patent number: 11649040Abstract: In one or more embodiments, a method for providing continuously variable feel forces for an aircraft comprises sensing, by each of at least one sensor associated with at least one aircraft control, a force sensor value. The method further comprises determining a net force value by using the force sensor value for each of at least one sensor. Also, the method comprises comparing the net force value to a desired breakout force. In addition, the method comprises determining whether the net force value exceeds the desired breakout force. Additionally, the method comprises determining an adjusted force value by using the desired breakout force and the net force value, when the net force value exceeds the desired breakout force. Also, the method comprises determining an actuator torque command based on the adjusted force value. Further, the method comprises commanding an autopilot actuator with the actuator torque command to apply torque.Type: GrantFiled: June 3, 2021Date of Patent: May 16, 2023Assignee: Tlie Boeing CompanyInventor: Joseph E.

Patent number: 10246178Abstract: An apparatus for controlling the pitch of an aircraft. The apparatus includes a horizontal control column extending from a control wheel horizontally towards a front wall of a cockpit. A pitch output link is connected to a downstream pitch control mechanism to transfer a force applied at the pitch output link to the downstream pitch control mechanism. A transfer assembly is connected to the horizontal control column and to the pitch output link. The transfer assembly translates a horizontal force applied to the horizontal control column to the pitch output link to provide the force applied to the downstream pitch control mechanism.Type: GrantFiled: July 7, 2016Date of Patent: April 2, 2019Assignee: The Boeing CompanyInventors: Joseph E.

Patent number: 5242552Abstract: The present invention resides in a process and apparatus for the electrolytic production of strong solutions of halogen oxyacids, more specifically for the production of such acids having a normality of about 0.1 to about 3.6 from the corresponding alkali metal salts of such acids. The present invention comprises establishing a solution of the corresponding alkali metal salt having a molar concentration less than that at which precipitation of said salt occurs. An electrolytic cell is provided comprising an anode compartment containing an anode, a cathode compartment containing a cathode, and a middle feed compartment intermediate the anode compartment and cathode compartment. The feed compartment is separated from the anode compartment by a diaphragm and from the cathode compartment by a cation-selective membrane. Means are provided for introducing said alkali metal salt solution into said middle feed compartment and for applying a voltage between the anode and cathode.Type: GrantFiled: July 25, 1991Date of Patent: September 7, 1993Assignee: Eltech Systems CorporationInventors: Richard J.

Patent number: 4377806Abstract: A parallel to serial converter is described for recording channel applications, wherein a coded symbol comprising a plural number of bits is to be rotated or converted to a serial stream. The converter includes a variable delay section which accepts the parallel code inputs on a plurality of lines and delays each input bit a predetermined number of counts, depending upon which line it is input on. The delay unit supplies a selector array of gates with bit signals, and the selector array reorders the bits into the desired serial stream. An output register is provided to reclock the serial stream prior to further channel processing.Type: GrantFiled: May 13, 1981Date of Patent: March 22, 1983Assignee: International Business Machines CorporationInventors: Joseph E.
