Abstract: A high-speed, portal-based system that can rapidly identify the presence of viruses such as COVID-19 and its antibodies in vivo. The system uses a low-power, stimulated emissions Nuclear Magnetic Resonance (NMR) effect and associated signal processing to detect the presence of organics characteristic of the virus (such as 15N, 14N, 1H, and/or 13C). The walkthrough portal enables non-invasive, real-time screening at a low cost. Detection can be reliably made in vivo when the virus or antibody is present in the saliva, chest, lungs, or other organs at total counts as low as 108 copies per ml.

Abstract: An improved remote keyless entry (RKE) system for a vehicle to provide enhanced capabilities to a user. The improved RKE system may utilize directional antennas in the vehicle and in the FOB. Directional antennas may utilize devices equipped with orientation-independent antennas to determine the location. The system can exist in many different customizable configurations, sometimes utilizing orientation-independent antennas embedded in the vehicle or the FOB. The devices, systems and methods described herein may be used for an RKE in personal or commercial vehicles.

Abstract: A human safe wireless charging system using a circularly polarized source antenna that can radiate in either a hemispherical pattern or directional cardiod-like patterns at a 40-50, 150, or 200 MHz frequencies to a receiving loop antenna which is coupled to a parasitic receive element.

Abstract: A wireless network accommodates mobile devices that provide directive radiation over multiple frequencies, multiple polarizations, and/or operate in modes that reduce unnecessary radiation into a nearby human body.

Abstract: A contact wire clamp includes a first clamp body and a second clamp body. The first clamp body and second clamp body each define a contact wire channel and a safety rope channel. The safety rope channel includes a plurality of ridges, each of the plurality of ridges spaced apart from neighboring ridges to define a plurality of troughs. The contact wire clamp further includes a mechanical fastener connecting the first clamp body and the second clamp body together. The safety rope channels of the connected first clamp body and second clamp body face each other and together form a safety rope passage.

Abstract: A tag incorporated with a directional antenna. Directional antennas may utilize devices equipped with orientation-independent antennas to determine the location of radio frequency signals emitted by other objects. The system can exist in many different customizable configurations, sometimes utilizing orientation-independent antennas embedded in the tag.

Abstract: A loop antenna in an electric vehicle receives energy wirelessly from a source external to the vehicle, such as from a series of Radio Frequency (RF) emitters embedded in a road surface. The use of single turn, RF loop antennas to both transmit and receive power greatly reduces the need to align the vehicle with the charging equipment.

Abstract: A low profile, conformal antenna assembly provides wide bandwidth, orientation dependent and directional operation via volumetric radiating elements that are diposed over a cavity. The volumetric antenna elements may be further controlled by embedded inductive or capacitive components and/or surrounded by frequency-selective components. An optional AM/FM radiating structure is provided by a conductive wire helix disposed within the cavity. The antenna assembly may be integrated with system and control, conversion, amplification and/or processing electronics in a single enclosure or tightly coupled enclosure space. Integrating the antenna subassembly with an electronics subassembly in the same enclosure eliminates the requirement for discrete RF signal connections reduces associated costs, and avoides signal losses in the connections to multiple vehicle systems. The antenna can be mounted to the inside surface of glass in a vehicle.

Abstract: A system for utilizing metadata created either at a central location for shared use by connected users, or at each individual user's location, to enhance user's enjoyment of available broadcast programming content. A variety of mechanisms are employed for automatically and manually identifying and designating programming segments, associating descriptive metadata which the identified segments, distributing the metadata for use at client locations, and using the supplied metadata to selectively record and playback desired programming.

Abstract: Methods and apparatus for identifying unwanted email messages by transmitting metadata with an outbound email message that indicates the total number of email messages sent by that sender in a predetermined time period, or alternatively indicates the total number of email messages which are equivalent to the outgoing message that have been sent. In addition the metadata may include an identification of the sender and a “pledge” made by the sender. A pledge may take the form of a binding commitment from the sender that the information contained in the metadata is accurate, and/or that the sender promises to abide by predetermined good conduct rules designed to limit unwanted email. The outgoing message may be further signed by the sender with a digital signature that provides means for verifying the content of the message and the pledge as well as the identity of the sender.

Abstract: A system, method and device to interrogate for the presence of objects, to prevent the inadvertent separation of the objects from their owner. An owner is alerted when they are separated from the objects by determining when a trigger event occurs, such as a person leaving and/or entering a particular monitored area or location. These monitored areas can be retrofitted with an electronic interrogation device that monitors local conditions to determine whether a user is entering or leaving the monitored area to trigger an interrogation of the personal items. The interrogation device is constructed and arranged to communicate with the objects to determine whether the objects are with the owner. The interrogation device automatically determines the presence of a particular object at the monitored environment and automatically generates a notification when needed. The system further controls functionality of the objects, according to illustrative embodiments, when the object is present.
