Abstract: A Vivaldi-Monopole antenna is a small form ultra-wideband antenna configured for low frequency operation in modern wireless devices. The Vivaldi-Monopole antenna comprises a tapered-slot element and a monopole element, wherein current modes of each element are combined to yield a functional and small form ultra-wideband antenna configured for low frequency resonances.

Abstract: Described herein are antenna designs and configurations that provide flexible solutions for creating compact antennas with multiple-band capabilities. For example, a hybrid PIFA-monopole antenna configuration and design is described. As another example, non-planar (e.g., orthogonal) and composite radiating structures incorporating various radiating element and ground plane configurations are described. Connective structures are also described for providing physical rigidity and ground plane connectivity to composite radiation elements. In embodiments described herein of composite radiating structures, multiple antennas may be included through passive radiating elements potentially combined with active circuitry. Composite radiating structures with multiple antennas may be used in multiple-in and multiple-out (MIMO) antenna applications.

The first and second substrates are joined by a bending line as a single substrate, where the said first substrate is allowed to be bent relative to the plane of the said second substrate.

Abstract: A planar monopole antenna for dual-band Wi-Fi application is disclosed. The antenna has a ground copper and a radiation copper. The radiation copper is adhered to a substrate and has an arrowhead-shaped pattern connected to a long-wide pattern. The arrowhead and long-wide patterns are aligned along the longitudinal direction of the antenna. The ground copper is adhered to the substrate and has a rectangularly-shaped pattern with an opening at one end thereof for the reception of the base of the long-wide pattern of the radiation copper in the longitudinal direction. Reception of the radiation copper into the opening of the ground copper forms an U-shaped separation that is approximately 0.6 mm wide. The antenna has a gross span of approximately 45 mm and a width of approximately 7 mm.

Abstract: A utility cart including a housing portion having a cabinet and a storage compartment disposed above the cabinet. A cover member is slidably mounted to the housing for movement between a first or closed position, in which the cover member is disposed above the storage compartment and substantially encloses the storage compartment, and a second or open position, in which the cover member is disposed in a cantilevered orientation with respect to the housing, such that the storage compartment is substantially exposed. A peripheral device, such as a projector, for example, may be stored within the storage compartment, such that the peripheral device is enclosed within the cart when the cover member is in its first position and is accessible when the cover member is in its second position. Additionally, the housing of the cart may include an electrical terminal incorporated therein for providing electrical power to the peripheral device.

Abstract: Two GPS units are mounted at two separate points on the body of a work machine to periodically measure their three-dimensional coordinates with respect to a chosen reference system. As soon as two sets of measurements are recorded, a plane is fitted through the four points so collected and it is used to determined the current orientation of the machine. As each additional set of position data is collected at predetermined intervals for the two points on the machine, a new plane equation is calculated to update the orientation of the machine based on a predetermined number of prior measurements. Standard-deviation analysis is used to check the validity of each plane calculation and the process is restarted when the deviation is found to be greater than an acceptable parameter.

Abstract: A jewelry finding or attachment means by which a charm is attached to a bracelet. The particular attachment means enables the charm to be removably attached at any desired location along the length of the bracelet at a location where the charm will be fully visible while at the same time not obscuring the upper surface of the bracelet and therefore not obstructing the view of any of the gemstones in the top surface of the bracelet. The attachment means further provides a safe and secure attachment with dual safety features to assure that the attachment and charm will not come loose and fall off the bracelet.
