Abstract: A coaxial connector (100) which includes first and second contact pins (104, 106), an outer contact member (102) and an inner alignment member (320). The inner alignment member can be electrically conductive and coaxially positioned within the outer contact member. The inner alignment member can include at least one substantially tubular portion (322) with opposing first and second end portions (324, 326). Each of the contact pins can include a first end portion (336, 338) contained within the substantially tubular portion, and a second end portion (344, 346) which extends beyond a respective end portion (324,326) of the inner alignment member. A spring (356) can be disposed between the first end portions of the respective contact pins to resiliently bias the contact pins in opposing directions.

Abstract: A durable coaxial connector (100) for providing a reliable signal connection to a printed circuit board (PCB) (118) while isolating the PCB from mechanical loads that are applied to the connector, and an electrical system incorporating the same. The connector can include a connector body (102) having a connector interface member (106), at least one flange (104), and a ground interface member (304) having a first portion (306) configured to be fixedly attached to the PCB and a second portion (308) configured to slideably mate to a ground interface receptacle defined in the connector body. A connector interface can be defined on an inner surface (410) of the connector interface member. A fastener (124) can couple the connector body to a heat sink (112). A thermally conductive boss (116) can be provided to mount the connector body (102) and transfer thermal energy from the connector body to the heat sink.

Abstract: A learning system method for infants, toddlers and young children which uses selected visuals stored on an audiovisual storage and playback device in conjunction with unique flash cards to provide an enhanced learning experience.

Abstract: Outside air is treated to remove moisture before it enters the conditioned air space of a store or other building containing refrigeration furniture. The sensible air temperature and relative humidity measurements are taken to allow microprocessor calculations of the wet bulb temperature. A pair of unequal sized compressors of the HVAC system are then cycled in stages for peak efficiency and minimum compressor horsepower usage for low cost operation and minimal energy consumption both of the HVAC system and the refrigeration furniture. The wet bulb temperature is converged by the microprocessor which iterates a known polynomial approximately every 6 seconds to derive the wet bulb temperature. A time delay circuitry set at approximately 30 minutes prevents unnecessary staging of the compressors.

Abstract: A personal travel assistant for a user includes a wireless communication device adapted to communicate with a base network having flight schedule information relating to a plurality of flights. The travel assistant stores time-based traveler location information, including different time periods and a traveler location associated with each of the time periods. A clock provides the current time for determining a current one of the time periods. A logic unit causes selective communication with the base network to selectively obtain flight schedule information, for example, for a first flight having a flight departure time after the expiration of the current time period, with the current traveler location as originating location, and the traveler next destination as destination location.

Abstract: An interconnect device for connecting components of high frequency communication systems, including RF and phased array applications. The device is capable of carrying RF and microwave signals between pairs of components and includes an outer conducting tube and an insulated conducting wire disposed within the tube. The outside diameter of the insulated wire is less than the inside diameter of the tube allowing movement of the wire relative to the tube. As a result of this movement, the longitudinal axis of the wire may vary from the longitudinal axis of the tube resulting in a “sloppy coax” interconnect. The ability of the wire to move within the tube facilitates installation and replacement of the wire when required.

Abstract: A cast core process is used to fabricate a very small, precision wound helical antenna having readily repeatable configuration parameters for use in a high GHz multi-element (e.g., phased array) antenna. A dielectric core member is formed by shaping a solid mandrel having a precision helical groove. After a mold is formed around the mandrel and cured, the mandrel is extracted, so that it may be used to make additional identical molds. A dielectric mixture is injected into the mold's cavity, and cured. The mold is then removed, and antenna wire is tightly wound and bonded into the dielectric core's helical groove. The antenna wire-wrapped core is then mechanically and electrically attached to a baseplate laminate structure, that includes a tuning circuit, so that the antenna may be physically mounted to a support member and connected to an associated transmit—receive module.

Abstract: The difference between the zone temperature and the scheduled setpoint, or .DELTA.t, is the basic data from each zone. Communication between the air handler control and the air terminal control is provided via the air system control so that the system is temperature, rather than pressure, responsive.

Abstract: A communication system for exchanging information between a remote terminal and a host terminal over a signalling channel of an ISDN network which does not need to establish communication over voice or data channels of the ISDN is disclosed. The communication system transmits credit transactions such as authorization requests from a remote terminal to a host computer, processes such transactions, and transmits a response back to the terminal, in which all such communication is performed over a signalling channel of ISDN. Preferably, the authorization request as well as the response from the host includes a "user-user information element" and are formatted in accordance with the CCITT Q.931 standard.

Abstract: An electrical plug assembly providing internal, adjustable gripping means and sealing means for electrical cords of various sizes. The internal, adjustable gripping means is a three-jaw grip assembly using pie-shape jaws which are slidably mounted on tracks and moved towards and away from the center of plug body to form a gripping circle around cords of various sizes. The cord seal consists of a notched rubber bushing formed between two rings. As the cover is tightened over the clamping jaws, the rings on either sides of the rubber bushing are urged together causing the bushing to collapse inward and seal the cord. The cord seal also provides means for locking the cord seal in place and increasing torque needed to remove the cover.

Abstract: An insulating liner for an electrical plug which fits between the plug body and the plug assembly when conductors are located. The liner rotates within the plug body and is retained in the plug body by a tab and groove.

Video images are stored on a videodisc, which images can be randomly accessed for display. The choice of which video images are displayed, or repeated, can be in response to the requests, or needs, of the recipient of the information.

Abstract: A one-piece, substantially flat and very thin heat exchanger core in accordance with this invention has two flat and parallel surfaces, with each of said surfaces being suitable as a mounting surface for a number of heat producing electronic chips. These surfaces are closely spaced and separated by a single cavity for conveying a fluid coolant, and the cavity contains a plurality of closely spaced pins extending the full distance between the parallel surfaces. The pins are formed and permanently joined to both of the parallel surfaces, and quite significantly, this is accomplished with creation of a seam. Each pin is capable of having a hole installed through for its entire length, from one of the flat surfaces to the other, without breaching the fluid cavity and without creating a path for fluid to leak from the fluid cavity to the ambient. Also significant is the novel method by which this heat exchanger is constructed.
