20150050879 | APPARATUSES, METHODS AND SYSTEMS FOR AUTHENTICATING A WIRELESS CONNECTION - In some embodiments, a wireless pairing method involves a touchscreen on a wireless host device combined with a switch on a wireless stylus device. The wireless pairing method uses the time-coincidence of a touch on the host device screen with the detection of a tip switch press on the stylus device as a mode of out-of-band communication to authenticate a pairing of the devices. In such embodiments, a user presses a tip portion of the stylus device against a pairing spot on the host device surface; the wireless devices then form a bonded pair if the touch and/or release of the tip portion of the stylus device with respect to the host device surface are within a pre-determined time co-incidence window of the detection by the host device of that touch and/or release of the tip portion of the stylus device. | 02-19-2015 |

20100026578 | Object locating apparatus, system and high-gain, high-selectivity antennae therefor - The invented system includes a beacon affixed to the object subject to loss and a tracker held by the owner of the lost object, the tracker repeatedly, electronically ‘interrogating’ the beacon with a radio frequency (RF) signal, the beacon repeatedly responding to the interrogation, and the tracker effectively triangulating to determine the lost object's nominal location by a measure of distance and direction. In accordance with one embodiment of the invention, the tracker includes one or more antenna each coupled with a power amplifier to determine in real time the distance and direction of the beacon from the tracker. In this embodiment, the tracker indicates both distance and direction of the object-affixed beacon to the tracker-holding owner via a simple color-coded light array. In one embodiment of the invention, the invented antenna of which there is one (or more) includes a helically wound conductor of elliptical cross section disposed around the hollow interior surface of a hollow mandrel. | 02-04-2010 |

20090052876 | Fins For An Electric Cable In An Electric Radiant Heating System - A heat-transferring fin is attached to an electric cable or to a packaged double cable of an electric radiant heating system. The fins can be attached using twist clips. Each twist clip includes an upper gripping member, a lower gripping member connected to the upper member by an upright support member, and a handle portion looping downwardly from the lower gripping member to enable a user to hold the clip and to manually twist the clip to cause the upper and lower gripping members to rotate relative to the fin and cable such that the fin and cable are clipped together. This twist clip enables quick and easy attachment of fins to cables, which greatly reduces the time and effort required to install an electric radiant heating system. This technology can be used in electric radiant floor heating or electric radiant wall heating. | 02-26-2009 |
