Abstract: A test fixture has a flexible plastic cable that acts as a waveguide. The Device-Under-Test (DUT) is a small transceiver and antenna that operate in the Extremely High-Frequency (EHF) band of 30-300 GHz. The size of the DUT transceiver is very small, limiting the power of emitted electromagnetic radiation so that close-proximity communication is used. The envelope for reception may only extend for about a centimeter from the DUT transceiver, about the same size as the test socket. A slot is formed in the test socket very near to the antenna. The slot receives one end of the plastic waveguide. The slot extends into the envelope by the DUT transceiver so that close-proximity radiation is captured by the plastic waveguide. The waveguide has a high relative permittivity and reflective metalized walls so that the radiation may be carried to a receiver that is outside the envelope.

The transmitting communication circuit may transmit a signal toward a second surface, and the receiving communication circuit may receive a signal relayed from the second surface. The detecting circuit may determine distance between the first surface and a second surface based on propagation characteristics of the signals.

Abstract: A communication device employs a contactless secure communication interface to transmit and receive data with a computing device using close proximity extremely high frequency (EHF) communication. The communication device and the computing device periodically initiate a discovery operation mode, whereby the devices periodically transmit identifying information about the respective devices and listen for identifying information from the other device. Upon completion of the discovery mode operation, the devices enter a link-training operation mode and exchange capability information about the respective devices. During transport mode operation the communication device employs methods to manage access to data stored on the communication device by encrypting the data using one or a combination of training information or capability information as a basis for generating an encryption key.

Abstract: Docked devices communicate wirelessly and in close proximity using multiple transmitters of Extremely High-Frequency (EHF) signals of 30-300 GHz. The devices may not be precisely aligned when docked. Tolerance of misalignment is improved by adding barriers such as solid metal blocks or rows of metal-filled vias that have a spacing of less than one-quarter the EHF wavelength. The barriers reflect EHF radiation and prevent EHF radiation from penetrating the barrier. Barriers placed between adjacent transmitters and receivers block stray electromagnetic radiation from causing cross-talk. The barriers can be placed closer to the transmitters than to the receivers to allow for a wider area for reception, permitting a wider misalignment. EHF reflecting features such as ground planes spaced a quarter-wavelength apart may be added to an end of a substrate near a connecting edge to act as a barrier and reflect electromagnetic radiation back toward an intended receiver.

In an exemplary embodiment, a cover for a bedding article includes a first cover portion having a first slide fastener tape, a second cover portion having a second slide fastener tape, and a single slider body configured to be maneuverable along the first slide fastener tape and the second slide fastener tape in order to bring a first row of slide fastener teeth into at least substantially interlocked arrangement with a second row of slide fastener teeth, thereby arranging the breakaway slide fastener into a closed configuration and pairing the first cover portion with the second cover portion around the bedding article.

Abstract: A method of installing a slide fastener assembly in a thin shell garment includes: providing a slide fastener chain comprised of two interlocked rows of teeth, each row of teeth being attached to a cord bundle of a respective slide fastener tape; removing the interlocked rows of teeth from a portion of the slide fastener chain, thereby defining a length of the slide fastener chain without teeth; introducing a reinforcing film to the cord bundles, at a location along the length of the slide fastener chain without teeth, to shape the cord bundles for accommodation of a pin and box assembly; cutting the slide fastener chain at a film-reinforced location along the length of the slide fastener chain without teeth, thereby defining a semi-finished slide fastener assembly terminating in a film-reinforced end; and attaching the semi-finished slide fastener assembly to one or more panels of a thin shell garment.

Abstract: A conventional zipper is the preferred means for closure of many jackets and other outerwear. Conventional zippers are prone to jamming and snagging due to the introduction of the liner into the slider body as the zipper is opened and closed. Embodiments herein provide modified slider bodies with one or more features such as an elongated spring cap, a protrusion on the bottom plate and/or plate coupler of the slider body, and/or vertically offset side rails. These features may minimize introduction of loose fabric, such as the lining of a lined garment, into the tape slot of the slider body, thereby help reduce jamming of the slider body during operation of the slide fastener.

Abstract: Slide fasteners (zippers) used for certain applications function better if the zipper tape can stretch in the lateral direction. When a zipper is used to close certain articles such as luggage, boots, or certain garments, it can be difficult to easily and fully close a zipper if there is a significant lateral load pulling at the tapes perpendicular to the direction that the slider is pulled. By using a zipper that includes a zipper tape that stretches in the lateral direction, it is possible to more easily close such articles while maintaining a neat appearance of the zipper on the article.
