Abstract: A first network device can implement null beamforming functionality to generate a NULL at a receive port of a second network device. In one embodiment, the first network device can estimate beamforming parameters to be used for transmitting the data signal to a first receive port of the second network device and for generating a null signal at a second receive port of the second network device, so that the second network device does not receive the data signal at the second receive port. In another embodiment, the first network device can estimate beamforming parameters to be used for transmitting the data signal to a receive port of the second network device and for generating a null signal at a receive port of a third network device, so that the receive port of the third network device does not receive the data signal.

Abstract: A multichannel communications medium may have two or more channels available for transmitting information. A first transmission signal and a second transmission signal may be prepared from a same analog signal to be transmitted on a first channel and a second channel. For example, a phase shift or amplitude shift may be performed on the first transmission signal or the second transmission signal. The first transmission signal may be transmitted via the first channel, and the second transmission signal may be transmitted via the second channel. The phase shift or amplitude shift may be performed by analog components that are less complex than digital signal processors used for digital signal diversity. The analog components may be digitally controlled. The analog signal diversity may utilize cost effective analog components to improve the performance of the communications system over single channel communications without requiring complex digital signal processing of multiple signal paths.

Abstract: The systems, devices, and methods described herein provide for the estimation and monitoring of cerebrovascular system properties and intracranial pressure (ICP) from one or more measurements or measured signals. These measured signals may include central or peripheral arterial blood pressure (ABP), and cerebral blood flow (CBF) or cerebral blood flow velocity (CBFV). The measured signals may be acquired noninvasively or minimally-invasively. The measured signals may be used to estimate parameters and variables of a computational model that is representative of the physiological relationships among the cerebral flows and pressures. The computational model may include at least one resistive element, at least one compliance element, and a representation of ICP.

Abstract: A powerline communication (PLC) device can be configured to execute functionality for zero cross sampling and detection. When the PLC device is directly coupled to a high-voltage PLC network, the PLC device can comprise printed safety capacitors in series with a high-voltage input AC powerline signal to safely couple the high-voltage AC powerline signal to the low-voltage processing circuit. The PLC device can also comprise an ADC to sample a scaled AC powerline signal and to obtain zero cross information. When the PLC device is part of an embedded PLC application, dynamic loading can affect the integrity of a low voltage zero cross signal that is used to extract zero cross information. After digitizing the zero cross signal, the PLC device can execute functionality to minimize/eliminate voltage drops caused by dynamic loading and obtain the zero cross information.

Abstract: A non-liner device (NLD) between powerline communication (PLC) devices can introduce significant distortion into the channel being utilized by the PLC devices. This distortion can create errors and corrupt data transmitted by the PLC devices. When trying to mitigate the effects of the distortion introduced by NLDs, PLC devices conform their mitigating actions to effectively satisfy a limit(s) set by a regulation and/or a standard. A PLC device implemented in accordance with this disclosure can mitigate the distortion effects with deference to regulatory/standard limits without knowledge of what types of NLDs and how many NLDs are coupled to the power line. A PLC device can use different techniques to infer the presence of an NLD in a PLC network. A PLC device can infer the presence of the NLD using a passive technique or one or more active techniques.
