Patent number: 11388812Abstract: An electronic controller is provided and includes a printed wiring board (PWB) on which electronics are operably disposed, a power supply configured to supply power to the electronics, a heat sink and one or more thermal conductors anchored to the PWB to assume and move between first and second connection states in first and second thermal conditions, respectively. The first connection states are characterized in that the one or more thermal conductors are thermally attached to the PWB and the power supply and thermally disconnected from the heat sink. The second connection states are characterized in that the one or more thermal conductors are thermally attached to the PWB and the power supply and to the heat sink.Type: GrantFiled: December 22, 2020Date of Patent: July 12, 2022Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Darrell E. Ankney, Nicholas Wlaznik

Patent number: 11015665Abstract: A proportional braking system is provided for use with a movable surface which is movable relative to a housing. The proportional braking system includes a variable displacement brake which is configured for displacement toward or away from braking engagement with the movable surface in proportion to an input command and a brake driver which is receptive of data reflective of movements of the movable surface relative to the housing and which issues the input command to the variable displacement brake in accordance with the data.Type: GrantFiled: January 24, 2018Date of Patent: May 25, 2021Assignee: HAMILTON SUNSTRAND CORPORATIONInventors: Darrell E. Ankney, Nicholas Wlaznik

Patent number: 10549864Abstract: An over torque detection system includes a mechanical torque sensor and a radio frequency identification (RFID) tag. The mechanical torque sensor includes first and second contact elements and a moveable element coupled to the first contact element. In a normal operational state the moveable element is in contact with the second contact element and creates an electrical pathway between the first and second contact elements and when in over torque operational state the movable element moves such that it does not contact the second contact element. The RFID tag is connected to the first contact element and the second contact element such that when the mechanical torque sensor is in the normal operation state the RFID tag does not transmit information, and when the mechanical torque sensor is in the over torque operation state the RFID tag does transmit information.Type: GrantFiled: May 7, 2018Date of Patent: February 4, 2020Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Darrell E.

Publication number: 20190226541Abstract: A proportional brake is provided and includes first and second bodies, a spring element, a coil and a booster coil. The first body includes brake plates and the second body includes thrust plates. The second body is disposed such that the thrust plates are interleaved with the brake plates and is rotatable and movable with respect to the first body. The spring element urges the second body to move toward the first body such that the thrust plates are urged toward braking engagements with the brake plates. The coil is provided at a first side of the brake plates and, when energized, generates a first flux moment on the second body in opposition to the spring element. The booster coil is provided at a second side of the brake plates and, when energized, generates a second flux moment on the second body in support of the spring element.Type: ApplicationFiled: January 24, 2018Publication date: July 25, 2019Inventors: Nicholas Wlaznik, Darrell E.

Publication number: 20130182479Abstract: A power rectification system includes power electronics configured to rectify an alternating current (AC) waveform to produce a direct current (DC) output voltage, a control circuit configured to control the power electronics based upon an error value, and a voltage reference control portion configured to provide the error value based upon a variable voltage reference and the DC output voltage. The variable voltage reference varies between the DC output voltage and a fixed voltage reference.Type: ApplicationFiled: January 17, 2012Publication date: July 18, 2013Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Nicholas Wlaznik, Timothy Michael Mayer

Publication number: 20120300519Abstract: A multi-phase active rectifier includes a plurality of active switching devices selectively controlled to convert a plurality of alternating current (AC) input voltages to a direct current (DC) output voltage. Control of the active switching devices is provided by a controller that includes an outer control loop for regulating the DC output voltage to a desired value, and an inner current loop for shaping the AC line current. The outer control loop compares the DC output to a threshold value to generate an error value, and multiples the error value with the plurality of monitored AC input voltages to generate modified AC input voltages. An inner control loop compares the modified AC input voltages with monitored AC line current values to generate a plurality of difference signals used to selectively control the plurality of active switching devices.Type: ApplicationFiled: May 26, 2011Publication date: November 29, 2012Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: James H. Clemmons, Nicholas Wlaznik
