Abstract: A method for coating glass, and specifically for manufacturing perfluoroalkoxy copolymer coated glass and tetrafluoroethylene perfluoromethyl vinyl ether copolymer coated glass. The method includes placing a glass substrate on an electrically grounded support and cleaning it with a solvent to remove impurities and prepare the surface of the substrate to be coated. The method also includes coating the surface with a primer and uniformly applying an electro-conductive enhance to the primer so that the surface of the glass substrate is wet, but not uneven. The method includes powder spraying periluoroalkoxy copolymer or tetrafluoroethylene perfluoromethyl vinyl ether copolymer on the electro-conductive enhancer while the enhancer is still wet. The method also includes securing the perfluoromethyl vinyl ether copolymer to the glass substrate by evaporating the electro-conductive enhance.

Abstract: A reinforcing underlayment including dry uniform particles evenly applied to a wet bonding material layer on a surface of a substrate. The substrate, including the layers, is then cured to harden the one or more of the layers. A final coating or topcoat is applied to the cured surface of the substrate. The dry particles are evenly distributed onto the bonding material layer creating a uniform surface for subsequent coatings. The dry particles increase the strength of the liquid coatings increasing solid particle density within the coating system and thereby imparting properties not available for the liquid coatings. The present invention enables a user to easily introduce very heavy, dense, strong particles into a liquid coating and allows the user to apply very dense, heavy particles into and onto a wet bonding material layer followed by a subsequent wet topcoat layer which is cured as one contiguous material with reinforcement and underlayment strengthening coming from the added, dry particles.

Abstract: A blank cut and scored for forming an electromagnetic interference shield is disclosed. The blank includes a rectangular bottom section and has first, second, third and fourth rectangular wall sections, wherein each wall section is joined to a separate side of the rectangular bottom section. Each of the first, second, third and fourth corner sections is formed by coaxial lines extending from the sides of the first, second, third and fourth rectangular wall sections and abut a corner of the rectangular bottom section. A perimeter area is contiguous with the first, second, third and fourth wall sections and first, second, third and fourth corner sections. In each corner section, a line diagonally bisects the corner section from the corner of the rectangular bottom section. First, second, third and fourth corner lines diagonally bisect each respective corner section from the corner of the rectangular bottom section through the abutting corner section into the perimeter area.

Abstract: An expanding joint is disclosed for increasing the size of an initially substantially planar member, upon stretching. The joint includes a discontinuous incision having a sinusoidal pattern extending transversely on an axis extending normal to the direction of stretching and being arranged in alternating concave and convex portions. Each of the concave and convex portions are discretely separated from the portions by an isthmus such that the incision widens upon application of tension in a direction substantially normal to the axis.

Abstract: A system which improves coverage in overlapping coverage areas between two type-A or type-B cellular radio telephone systems is able to direct a subscriber unit in the overlapping coverage area to the home or primary system, thereby minimizing the subscriber unit's roaming-type expenses. The system includes a control channel receiver, a control unit, and a control channel transmitter/receiver pair, in combination with a transmit/receive antenna. The system transmits a control channel, which is associated with the home system, into the overlapping region. The control channel is intended to be the strongest channel in that region. Any subscriber units in the region associated with the home system which respond to that control channel will be directed to other control channels associated with the home system. Those subscriber units will receive service from the home system, as opposed to the foreign system which may provide other strong control channels in the overlapping coverage area.

Abstract: A booster usable in a radio telephone communication system can amplify and repeat both analog and digital representations of communications. The unit monitors control channel communications going to subscriber units and reverse control channel responses from subscriber units. When a digital traffic channel assignment is detected, the booster directs the subscriber unit to a different traffic channel pair. The booster communicates with the subscriber unit on the traffic channel pair assigned by it to the subscriber unit. The booster communicates with the cell site on the channel pair assigned by the cell site. Digitized communications from the subscriber unit are amplified only during the associated time intervals. Hence, other communications in different time intervals on the same message channel are not effected. Analog conversations and other message channels can be simultaneously boosted and retransmitted.

Abstract: A system and method for handing back a movable transceiver to a different cell site from the original cell site includes circuitry for sensing signals from the movable transceiver which are transmitted on a modified frequency as well as circuitry for translating those signals back to their originally assigned frequencies without changing the detected field strength of the signal, in combination with circuitry for forwarding the translated signals to the different cell site for hand-off evaluation. The method includes sensing the received signals, translating the received signals to an originally assigned frequency based on either a fixed offset or other provided information concerning the translation along with a step of continually updating those frequencies which are to be retranslated.

Abstract: A multi-resonator notch filter incorporates a variable impedance transmission line with impedance values going from a relatively low value and increasing upward to a relatively high value then back down to a relatively low value again. A plurality of resonant cavities is coupled to the relatively high central impedance line section of the filter at odd multiples of quarter wavelength intervals. Other resonators can be coupled to lower impedance sections of the transmission line. The locations of selected resonators on the quarter wavelength intervals can be altered thereby increasing and decreasing the nominal quarter wavelength intervals of selected internal pairs by a predetermined amount thereby providing acceptable levels of performance with fewer resonators.

Abstract: A diversity receiving apparatus includes first and second antennas and circuitry for selecting one antenna or the other. Control circuitry analyzes signal strength received from the selected antenna and determines when the antennas should be switched. The antennas are switched when the received signal strength falls below a running average thereof; the received signal strength falls below a threshold value; or a predetermined time has elapsed since the antennas have been switched. The antennas are switched when the received signal strength falls below a running average thereof; the received signal strength falls below a threshold value; or a predetermined time has elapsed since the antennas have been switched.
