20080289073 | Flexible knee pad with rotating knee support cushion - A flexible knee pad of the kind to be worn over the knee of a workman who must kneel down for long periods of time while working on a work surface. According to a preferred embodiment, the flexible knee pad includes an upper knee support cushion against which the workman's knee is laid, a lower pivot support base to rest upon the work surface, and an intermediate pivoting reinforcement plate having a flat bed upon which the knee support cushion is seated. The intermediate pivoting reinforcement plate includes a pair of pivots that are coupled to respective pivot slots formed in the lower pivot support base. Accordingly, the pivoting reinforcement plate, the knee support cushion seated thereon, and the workman's knee are all suspended by and rotatable relative to the pivot support base above the work surface so as to advantageously reduce pressure applied to the workman's knee cap by the work surface should he rock his body and shift his weight back and forth over the work surface. | 11-27-2008 |
20090260317 | Rotatabel wedge tile spacer having a curved body - A rotatable wedge tile spacer to be removably positioned in a gap between adjacent upper and lower tiles that are being bonded one above the other to a vertical surface (i.e., a wall). The tile spacer includes a curved (i.e., circular) body having a thin tip at one end and a thick tail at the opposite end. The height of the circular body increases along a tile-supporting top surface thereof that runs from the thin tip to the thick tail. With the tile spacer seated upon the lower tile, the circular body is rotated continuously around its longitudinal axis until the tile-supporting top surface engages the upper tile. Accordingly, the circular body of the rotatable wedge tile spacer will fill the gap and thereby prevent the upper tile from moving through the gap towards the lower tile during the bonding process. | 10-22-2009 |
20120112030 | Adjustable leg support - An adjustable leg support for providing support to and stabilizing a leg of a table, chair or similar article that is shorter than the other legs to prevent the article from wobbling. The adjustable leg support includes a screw-threaded rotatable base that is detachably coupled in surrounding engagement to a correspondingly threaded platform. The platform has a flat shelf that is laid upon the floor below the short leg to be supported. A rotational force is applied to the rotatable base which causes an axial displacement of the platform upwardly through the base towards the short leg. Rotation of the base continues until the flat shelf of the platform is raised and the short leg is seated on the shelf by which to eliminate the gap between the short leg and the floor. The rotatable base and the platform are mated to one another along opposing sets of screw threads that lie outside and surround the short leg to be stabilized. | 05-10-2012 |

20090046028 | ANTENNA WITH VOLUME OF MATERIAL - An antenna includes one or more antenna elements and a volume of material contained at least partly within a volume of the one or more antenna elements. The volume of material has at least one electromagnetic property that is different from free space. The volume of material may include dielectric material and/or ferrite material. The antenna elements may be isolated magnetic dipole (IMD) antenna elements. The electromagnetic property may be permeability and/or permittivity. | 02-19-2009 |
20090051611 | ANTENNA WITH ACTIVE ELEMENTS - A multi-frequency antenna comprising an IMD element, active tuning elements and parasitic elements. The IMD element is used in combination with the active tuning and parasitic elements for enabling a variable frequency at which the antenna operates, wherein, when excited, the parasitic elements may couple with the IMD element to change an operating characteristic of the IMD element. | 02-26-2009 |
20090096693 | LOW FREQUENCY ANTENNA - An antenna includes a core formed of a high-permeability material and a coil wire wrapped around at least a part of the core. In one embodiment, the high-permeability material includes ferrite material. | 04-16-2009 |
20090243951 | MULTI-LAYER ISOLATED MAGNETIC DIPOLE ANTENNA - A multi-layer isolated magnetic dipole (IMD) with improved bandwidth and efficiency characteristics to be used in wireless communications and other applicable systems. The multi-layer IMD antenna comprises an IMD element positioned above a ground plane, a conductive element positioned above a ground plane and coupled to the first portion having one or more slot regions being defined between the IMD element and the conductive element and one or more capacitive elements positioned across the one or more slot regions. The range of frequencies covered to be determined by the shape, size, and number of elements in the physical configuration of the components. | 10-01-2009 |
20110012800 | ANTENNA WITH ACTIVE ELEMENTS - A multi-frequency antenna comprising an IMD element, one or more active tuning elements and one or more parasitic elements. The IMD element is used in combination with the active tuning and parasitic elements for enabling a variable frequency at which the antenna operates, wherein, when excited, the parasitic elements may couple with the IMD element to change an operating characteristic of the IMD element. | 01-20-2011 |
20120280871 | ANTENNA WITH ACTIVE ELEMENTS - A multi-frequency antenna comprising an IMD element, one or more active tuning elements and one or more parasitic elements.
