International Classification:

A61B 5/08

US Classification:

600534

Abstract:

A radar-based physiological motion sensor is disclosed. Doppler-shifted signals can be extracted from the signals received by the sensor. The Doppler-shifted signals can be digitized and processed subsequently to extract information related to the cardiopulmonary motion in one or more subjects. The information can include respiratory rates, heart rates, waveforms due to respiratory and cardiac activity, direction of arrival, abnormal or paradoxical breathing, etc. In various embodiments, the extracted information can be displayed on a display.

International Classification:

H01Q 9/04
H01Q 1/22

Abstract:

Various embodiments provide systems, devices, and methods for an antenna assembly included in an integrated circuit (IC) package. The antenna assembly may be used for near field wireless communication such as package-to-package and/or chip-to-chip communication. The antenna assembly may include a feed plate (e.g., a top feed) that is capacitively coupled to a first via and a second via. The feed plate may further be capacitively coupled to a loading structure. The first via may be conductively coupled to a ground potential. In some embodiments, the antenna assembly may further include a stub structure (e.g., an open stub or a short stub) that is conductively coupled to the second via. An impedance matching network may be coupled between the feed plate and an IC die that communicates using the antenna assembly. Other embodiments may be described and claimed.

International Classification:

H01Q 21/20
H01Q 13/10
H01Q 3/24

Abstract:

Monodirectional antennas may be arranged to radiate in a near omni-directional pattern. By incorporating switches into the antenna arrangement, the antennas can be controlled to selectively radiate from a common radiofrequency feed. These arrangements may be packaged in a housing, which may aid both in antenna performance and in antenna installation. According to another aspect of the disclosure, housings may include a plurality of antennas, and one or more procedures may be implemented to determine a codebook to radiate from the circular arrangement according to various beam constrains.

International Classification:

H04B 1/48
H01Q 13/02

Abstract:

A radio frequency front end and an antenna front end may be separated from one another to maintain close proximity between a low noise amplifier and an antenna while achieving improved thermal regulation of a power amplifier. The radio frequency front end antenna front end may include a duplexing system that enables operation with a single electrical cable. Furthermore, where it is desired to transmit a radiofrequency signal via a waveguide, a flexible waveguide may be constructed with a distributed capacitance between waveguide protrusions.
