Patent number: 11979992Abstract: An electronic medical device is disclosed here. An exemplary embodiment of the medical device includes a printed circuit board assembly, a protective inner shell surrounding at least a portion of the printed circuit board assembly, and an outer shell surrounding at least a portion of the protective inner shell. The printed circuit board assembly has a printed circuit board, electronic components mounted to the printed circuit board, a battery mounted to the printed circuit board, and an interface compatible with a physiological characteristic sensor component. The protective inner shell is formed by overmolding the printed circuit board assembly with a first material having low pressure and low temperature molding properties. The outer shell is formed by overmolding the protective inner shell with a second material that is different than the first material.Type: GrantFiled: August 24, 2021Date of Patent: May 7, 2024Assignee: Medtronic MiniMed, Inc.Inventors: Claire F.

Patent number: 11962085Abstract: This document a two-part folded waveguide with horns. For example, a waveguide includes a channel with an opening in a longitudinal direction at one end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the channel. One part of the waveguide defines a surface of the channel featuring a plurality of radiation slots in the shape of a horn, which allows the two parts of the waveguide to be arranged and configured as one component. A first part of the waveguide has slots and an upper half of the walls of the channel and a second part provides a lower half of the walls of the channel and a surface of the channel opposite the slots. Using horns in combination with two parts enables ease of manufacturing a waveguide with an internal channel having a folded or sinusoidal shape.Type: GrantFiled: July 29, 2021Date of Patent: April 16, 2024Assignee: Aptiv Technologies AGInventor: Shawn Shi

Patent number: 11757165Abstract: This document describes a folded waveguide for antenna. The folded waveguide may be an air waveguide and includes a hollow core that forms a rectangular opening in a longitudinal direction at one end, a closed wall at an opposite end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the hollow core. The hollow core forms a plurality of radiation slots, each including a hole through one of multiple surfaces that defines the hollow core. The radiation slots are arranged on the one surface to produce a particular antenna pattern. The radiation slots and sinusoidal shape enable the folded waveguide to prevent grating lobes from appearing in the particular antenna pattern on either side of a horizontal-polarity, main beam, or to prevent X-band lobes from appearing in the particular antenna pattern on either side of a vertical-polarity, main beam.Type: GrantFiled: July 15, 2022Date of Patent: September 12, 2023Assignee: Aptiv Technologies LimitedInventor: Shawn Shi

Patent number: 11721905Abstract: This document describes a waveguide with a beam-forming feature with radiation slots. The beam-forming feature of the waveguide includes recessed walls surrounding a plurality of radiation slots. The recessed walls of the waveguide may be walls of equal height and width, or they may include further features that manipulate the beam being formed for certain applications. Some examples of these further features are the inclusion of a choke on one wall, one wall having a height greater than a parallel wall, or the walls either including a step or a taper, such that the beam-forming feature is narrower near the surface of the waveguide with the radiation slots and wider further from the surface of the waveguide with the radiation slots. The beam-forming feature may reduce grating lobes in the radiation pattern thereby improving accuracy and performance of the host system.Type: GrantFiled: July 9, 2021Date of Patent: August 8, 2023Assignee: Aptiv Technologies LimitedInventor: Shawn Shi

Patent number: 11681015Abstract: This document includes techniques, apparatuses, and systems related to a waveguide with squint alteration, which can improve electromagnetic wave operation. In aspects, squint of electromagnetic waves pertaining to waveguides may be altered and improved. In this example, the techniques also enable the waveguide to direct electromagnetic waves according to respective chambers and one or more apertures, improving the quality of signals transmitted and received. The chambers may be divided according to a divider extending toward an opening of the waveguide, directing electromagnetic waves between the opening and the one or more apertures.Type: GrantFiled: March 18, 2021Date of Patent: June 20, 2023Assignee: Aptiv Technologies LimitedInventors: Alireza Foroozesh, Shawn Shi

Patent number: 11668787Abstract: This document describes techniques, apparatuses, and systems for a waveguide with lobe suppression. A waveguide is described that includes a pipe for containing a dielectric, the pipe defining an open end to a longitudinal direction through the pipe. An array of radiating slots is formed through a surface of the pipe and in communication with the dielectric. To suppress grating lobes in an antenna pattern, the waveguide includes at least one parasitic groove that is separate from the pipe and with at least a portion of a length that is parallel to the array of radiating slots. In this way, the waveguide provides an antenna pattern where grating lobes are suppressed or substantially reduced.Type: GrantFiled: January 29, 2021Date of Patent: June 6, 2023Assignee: Aptiv Technologies LimitedInventor: Shawn Shi

Patent number: 11588228Abstract: This document describes techniques and systems of an exposed portion of a PCB configured to provide isolation among radar antennas. The described radar system includes an exposed portion of a surface of a printed circuit board (PCB) positioned between a first antenna and a second antenna. The PCB includes a metal plating on the surface of the PCB. A width of the exposed portion can delay a phase of electromagnetic (EM) energy conducted by the metal plating relative to a phase of EM energy that does not traverse the exposed portion. A height of the exposed portion can cause an amount of the EM energy conducted by the metal plating to be approximately equal to an amount of EM energy that traverses the exposed portion. In this way, the described systems and techniques can reduce signal-coupling among radar antennas without additional hardware costs and distance between the antennas.Type: GrantFiled: November 1, 2021Date of Patent: February 21, 2023Assignee: Aptiv Technologies LimitedInventor: Shawn Shi
