US Patent for Techniques for device-to-device communications Patent (Patent # 9,929,775 issued March 27, 2018) - Justia Patents Search
Embodiments of the present disclosure provide apparatuses and systems for proximity communications. The apparatus may include an integrated circuit (IC) package with a central processing unit (CPU) circuit, an input-output (I/O) circuit coupled with the CPU circuit, and a dielectric electromagnetic waveguide coupled with the I/O circuit, to enable communications between the CPU circuit and another apparatus. In another instance, the apparatus may include a plurality of coupler pads disposed on a first surface of the apparatus; and a processor electrically coupled with the coupler pads. One of the coupler pads may form capacitive coupling with one of coupler pads disposed on a second surface of another apparatus, in response to a placement of the first surface in at least partial contact with the second surface, to enable proximity data communication between the processor and the other apparatus. Other embodiments may be described and/or claimed.
US Patent for System and method for signal interference rejection using human body communication Patent (Patent # 11,374,602 issued June 28, 2022) - Justia Patents Search
A communication interference rejection system comprising a receiver operatively connected to a device connected to a body of a user. The receiver is configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, the interference component due to human body antenna effect. The receiver is configured to integrate the signal using a relatively low-gain analog integrator and then digitally differentiate the output of said integration.
US Patent for Human body communication interference rejection system Patent (Patent # 11,387,854 issued July 12, 2022) - Justia Patents Search
A communication interference rejection system, comprising a dual data rate (DDR) receiver operatively connected to a device connected to a body of a user. The DDR receiver is configured to receive a signal transmitted through the body of the user, with the signal comprising a relatively substantially small constant amplitude component and a relatively large sinusoidal or modulated interference component, said interference component due to human body antenna effect. The receiver integrates the signal and sample at a sampling time, with the sampling time defined as Ts=n/Finterference, wherein Finterference is the frequency of the modulated interference component and n is an integer.
