Patent number: 11592502Abstract: An integrated sensor includes a sensor cell, a signal source, an input optical rotator, and a signal detector. The integrated sensor includes a positioner for a signal-processing component. The positioner may be a linear positioner for the signal-processing component, such as a signal source or a signal detector, or may be a rotational positioner for the signal-processing component, such as a polarizer or a polarized signal source. The signal-processing component is located on a signal path of the integrated sensor. A method of adjusting a linear position or rotational position of a signal-processing component is also disclosed. A linear position or a rotational position of the signal-processing component may be adjusted to improve performance of the integrated sensor.Type: GrantFiled: July 12, 2017Date of Patent: February 28, 2023Assignee: Texas Instruments IncorporatedInventors: Roozbeh Parsa, Ann Gabrys

Patent number: 11294002Abstract: An integrated microfabricated sensor includes a sensor cell having a cell body, a first window attached to the cell body, and a second window attached to the cell body. The cell body laterally surrounds a cavity, so that both windows are exposed to the cavity. The sensor cell contains a sensor fluid material in the cavity. The cavity has concave profiles at cell body walls, so that the cavity is wider in a central region, approximately midway between the first window and the second window, than at the first surface and at the second surface. The cell body walls of the cell body have acute interior angles at both windows. The cell body is formed using an etch process that removes material from the cell body concurrently at the first surface and the second surface, forming the acute interior angles at both the first surface and the second surface.Type: GrantFiled: July 1, 2020Date of Patent: April 5, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ann Gabrys, Nathan Brockie, Terry Dyer, Roozbeh Parsa, William French

Patent number: 11193990Abstract: An integrated microfabricated alkali vapor cell sensor includes two alkali vapor regions, with a signal path through each. One or two signal emitters, with associated optical signal rotators, such as quarter wave plates, provide circularly polarized input signals into the alkali vapor regions, so that a first signal through the first alkali vapor region is circularly polarized in an opposite direction from a second signal through the second alkali vapor region. Output signals from the two alkali vapor regions are transformed to linearly polarized signals and then measured by one or more signal detectors. A first Larmor frequency is estimated from the output signal from the first alkali vapor region, and a second Larmor frequency is estimated from the output signal from the second alkali vapor region. A heading error-free Larmor frequency is estimated from the first Larmor frequency and the second Larmor frequency.Type: GrantFiled: June 13, 2017Date of Patent: December 7, 2021Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Roozbeh Parsa, David Brian McDonald, Ann Gabrys, Paul Mawson, Anston Joel Lobo

Patent number: 10591872Abstract: An integrated microfabricated sensor includes a sensor cell having a cell body, a first window attached to a first surface, and a second window attached to a second surface, opposite to the first window. The cell body laterally surrounds a cavity, so that the first window and the second window are exposed to the cavity. The sensor cell contains a sensor fluid material in the cavity. The cell body has recesses on opposing exterior sides of the cell body; each recess extends from the first surface to the second surface. Exterior portions of the cell body wall in the recesses are recessed from singulation surfaces on the cell body exterior. The cell body is formed by etching the cavity and the recesses concurrently through a body substrate. After the windows are attached, the sensor cell is singulated from the body substrate through the recesses.Type: GrantFiled: March 13, 2017Date of Patent: March 17, 2020Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Roozbeh Parsa, Iouri N Mirgorodski, William French, Nathan Brockie, Ann Gabrys, Terry Dyer

Patent number: 10409227Abstract: A microfabricated sensor includes a sensor cell with a cell body and a window attached to the cell body. A sensor cavity containing sensor fluid material is located in cell body, open to the window. A signal path extends from a signal emitter outside the sensor cell, through the window and sensor cavity, and to a signal detector. The sensor cell may have an asymmetric thermal configuration, conducive to developing a temperature gradient in the sensor cell. One or more heaters are disposed on the sensor cell, possibly in an asymmetric configuration. Power is applied to the heaters, possibly asymmetrically, so as to develop a temperature gradient in the sensor cell with a low temperature region in the sensor cell, sufficient to condense the sensor fluid in the low temperature region, outside of the signal path.Type: GrantFiled: August 3, 2016Date of Patent: September 10, 2019Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Roozbeh Parsa, Iouri N Mirgorodski, William French, Nathan Brockie, Ann Gabrys, Terry Dyer

Publication number: 20180341281Abstract: A microelectronic device includes a substrate, a first component thermally coupled to the substrate at a first area, a second component thermally coupled to the substrate at a second area, a heat source thermally coupled to the substrate at a third area, and a thermal sink thermally coupled to the substrate at a fourth area. A thermal path extends from the first, second, and third areas to the fourth area. The thermal path includes a low thermal conductivity region between the fourth area and the first, second, and third areas. A programmable thermal shunt is disposed across the low thermal conductivity region. The programmable thermal shunt is configured in one of a high thermal conductance state or a low thermal conductance state. The thermal conductance state may be changed from the high thermal conductance state to the low thermal conductance state to the other state, or vice versa.Type: ApplicationFiled: May 23, 2017Publication date: November 29, 2018Applicant: Texas Instruments IncorporatedInventors: Roozbeh Parsa, Ann Gabrys, Iouri N.
