Patent number: 11879925Abstract: A test apparatus for testing device under test (DUT) having an antenna located on the DUT is disclosed. The test apparatus includes: a housing, a socket configured to electrically connect the DUT to a load board, a gripper assembly configured to hold the DUT in place, a retractor configured to release the DUT from the gripper assembly, and an alignment plate configured to align the DUT with the socket. The gripper assembly includes a base and an extender, the base is attached to the housing, and the extender is configured to hold the DUT in place. When the retractor is disengaged from the extender, the extender is configured to hold the DUT in place. When the retractor is engaged with the extender, the extender is configured to release the DUT on the alignment plate.Type: GrantFiled: April 14, 2021Date of Patent: January 23, 2024Assignee: Johnstech International CorporationInventors: Mike Andres, David Johnson, Jason Steinblock

Publication number: 20230184826Abstract: A contactor assembly for a testing system for testing integrated circuit devices includes a contact, and a housing having a contact slot. The contact is receivable in the contact slot. The contact includes a tip, a body, and a tail; and is configured to be in a free state, a preload state, and an actuated state. The housing includes a housing backstop. When the contact is in the preload state, a contact backstop of the contact is biased against the housing backstop.Type: ApplicationFiled: November 1, 2022Publication date: June 15, 2023Inventors: Melissa Hasskamp, David Skodje, Mike Andres

Patent number: 11674998Abstract: A contactor assembly for a testing system is disclosed. The assembly includes a contact having a contact tail and a housing having a top surface and a bottom surface. A slot extends through the housing from the top surface to the bottom surface and defines a first inner side wall of the housing and a first inner end wall. The contact is receivable in the slot. The contact tail includes a sloped terminus. A retainer is disposed on the first inner side wall. When the sloped terminus is engaged with the first inner end wall, at least a portion of the retainer overlaps with the contact forming at an overlapping area in a cross-sectional view, thereby preventing removal of the contact from the top side of the housing.Type: GrantFiled: October 1, 2021Date of Patent: June 13, 2023Assignee: Johnstech International CorporationInventors: Bob Chartrand, David Johnson, Brian Sheposh, Mike Andres

Patent number: 6608418Abstract: A turbo-generator machine for producing a supply of cooled air and a supply of electric power has a permanent magnet generator fixed to a shaft which is driven by a turbine rotor, the turbine serving to expand air which is supplied thereto. Magnetic bearings support the shaft radially for rotation about a precisely established axis while a magnetic thrust bearing keeps the shaft in a precisely fixed axial position. Power for the magnetic bearings is supplied by the turbo-generator during operation. Generator air gap is sized in coordination with the magnetic bearing air gap, and the generator stator and shaft are sized to minimize leakage flux from the generator to minimize interaction between the permanent magnet rotor and the magnetic bearings.Type: GrantFiled: August 24, 2001Date of Patent: August 19, 2003Assignees: Smiths Aerospace, Inc., Electronic Systems RockfordInventors: Mike Andres, Terry Temple, Terry Coons

Patent number: 6545373Abstract: A ballast load control system and method is presented that regulates the output electrical power supplied by a turbo-generator such that appropriate turbine loading may be achieved. Such enables the use of a turbo-generator having an expansion turbine to be used to provide a controlled, required amount of cooling to a thermal control system. By effectively varying the coupled electrical load, the loading provided to the expansion turbine may be controlled while maintaining output power requirements to connected electrical utilization equipment. Use of a common system controller for both the cooling system and ballast trim load system of the present invention ensures coordinated operation between the required amount of cooling and electrical power quality supplied to the coupled utilization equipment.Type: GrantFiled: August 24, 2001Date of Patent: April 8, 2003Assignee: Smiths Aerospace, Inc.Inventors: Mike Andres, Terry Temple, Daniel E. Brady

Patent number: 5726560Abstract: A switched reluctance generator that can be used in an air cycle machine, where the generator uses the energy from the shaft of the air cycle machine to provide a back-up power supply to the magnetic bearings supporting the shaft. The generator includes circuitry for comparing the non-commutated excitation current with a command signal to regulate the excitation current, thereby regulating the generator output voltage.Type: GrantFiled: September 1, 1995Date of Patent: March 10, 1998Assignee: Barber-Colman CompanyInventors: Kenneth J.
