A vertically integrated Ka-band active electronically scanned antenna including, among other things, a transitioning RF waveguide relocator panel located behind a radiator faceplate and an array of beam control tiles respectively coupled to one of a plurality of transceiver modules via an RF manifold. Each of the beam control tiles includes a respective plurality of high power transmit / receive (T / R) cells as well as dielectric waveguides, RF stripline and coaxial transmission line elements. The waveguide relocator panel is preferably fabricated by a diffusion bonded copper laminate stack up with dielectric filling. The beam control tiles are preferably fabricated by the use of multiple layers of low temperature co-fired ceramic (LTCC) material laminated together. The waveguide relocator panel and the beam control tiles are designed to route RF signals to and from a respective transceiver module of four transceiver modules and a quadrature array of antenna radiators matched to free space formed in the faceplate. Planar type metal spring gaskets are provided between the interfacing layers so as to provide and ensure interconnection between mutually facing waveguide ports and to prevent RF leakage from around the perimeter of the waveguide ports. Cooling of the various components is achieved by a pair of planar forced air heat sink members which are located on either side of the array of beam control tiles. DC power and control of the T / R cells is provided by a printed circuit wiring board assembly located adjacent to the array of beam controlled tiles with solderless DC connections being provided by an arrangement of “fuzz button” electrical connector elements.

A key assignment method assigns large sets of alphabetic and other characters and functions to the keys of a standard numeric keypad for text / data entry on an electronic device. Two letters are assigned in pairs to each key of the standard 12-key keypad in a first character mode, and other symbols, characters, or infrequently used letters are assigned in a second or more optional character modes. A mode selection key is provided to select between the modes. In the first character mode, a keypress of a key selects the first letter of the pair and two keypresses in succession selects the second letter. The letter pairs may be assigned in alphabetic order, except for infrequently used letters, such as ‘Q’ and ‘Z’, or in QWERTY order, or in pairs of a more frequently-used letter with a less frequently-used letter. By comparison to the standard phone keypad layout having an average KPD=2.2, this method can achieve a KPD=1.4 or lower. The standard directional arrow keys (RDI keys) may be used for mode selection in multiple character modes. Using the RDI mode selector can transform the conventional 12-key telephone keypad into the equivalent of a 60-key data entry layout (or expandable by 48 more keys for each additional mode keystroke used), thereby allowing operation comparable to a full QWERTY keyboard of characters, with enhanced symbols and functions, and / or with multi-language character sets.

Embodiments of the invention are concerned with a business card dispenser that presents a single card to the user, when the front of the dispenser is pushed. The dispenser can hold over one hundred cards, plus one protected display card to show the contents of the dispenser.

This is accomplished by use of a plunger, which pushes through a slot a single card, partially exposing it outside of the dispenser. Hence, allowing the user to grab the card with two fingers and pull it to retrieve the card.
