Abstract: A bar code reader system is required to be integrated into an energy dispenser that is able to read a variety of bar code formats printed on a variety of media. The bar code reader system accepts both bar encoded cards having very low aspect ratios and other printed bar encoded media having differing aspect ratios. The system also provides a robust scanning pattern such that other printed bar encoded media can be placed into a receiving cavity without regard to a particular orientation. Further, the system provides a sensing mechanism capable of determining when a card has been inserted into the system or when another bar encoded media has been placed into the receiving cavity.

Abstract: A new and improved method of dispensing, tracking and managing pharmaceutical product samples by communicatively linking prescribers and pharmacies to a central computing station. The method entails utilizing product trial media that is exchanged for actual pharmaceutical product. The media is encoded with information that identifies a particular pharmaceutical trial product, such as by magnetic encoding similar to that used with credit cards. The media is distributed to participating medical doctors or prescribers who then activate the media via the central computing station. The prescriber then transfers the activated media to patients who then present the media to participating pharmacies. Before filling the pharmaceutical trial product identified by the media, the pharmacy validates the media via a link with the central computing station. Then, the pharmacy dispenses the prescribed pharmaceutical trial product.

Abstract: A mobile terminal includes power control logic which limits the maximum transmit power of the mobile radio telephone to conserve battery power when it is operated in a hand-held mode. The mobile radio telephone includes power control logic which sets the transmit power in response to power control codes received from a base station. The power control codes transmitted from the base station correspond to designated power levels. A signal is generated to indicate whether the mobile radio telephone is operated in a hand-held mode. When the mobile radio telephone is operated in a hand-held mode, the power control logic sets the power level at a maximum hand-held power level which is less than the maximum transmit power level.

Abstract: An overhead cabling system for a telecommunications switching center including one or more cable chute assemblies, a plurality of cable tray assemblies, and one or more cable ladder assemblies. The cable chute assemblies are mounted to the floor adjacent the ends of the cabinet suites. The cable ladder assemblies are supported by the cable chute assemblies and extend cross aisle between two or more cabinet suites. The cable tray assemblies are mounted to the tops of the cabinets which provide the sole support for the cable tray assemblies. The cable tray assemblies are modular and designed to fit on top of a single cabinet. The overhead cabling system does not require support from the walls or ceiling of the telecommunications center.

Abstract: A spectrogram of secondary magnetic field strength as a function of frequency and spatial relationship is used to identify hidden objects. A time-varying multi-frequency primary electromagnetic field is generated, preferably over the range 100 Hz to 300 kHz, which induces a time-varying multi-frequency secondary electromagnetic field about the hidden object. The strength of the secondary field, typically inphase and quadrature, is plotted as a spectrogram over a low frequency broadband spectrum as a function of frequency and spatial relationship between the hidden object and the secondary field strength detector. From this spectrogram, indications may be had of the hidden object's characteristics such as location, size and shape, and material composition. Preferably, the measured spectrogram is compared against a library of reference spectrograms by a computer to identify the hidden object.

Abstract: A radiotelephone having a wave guide for channeling sound energy from a speaker to the ear of a person utilizing the radiotelephone. The wave guide is disposed adjacent the speaker and acts to direct sound energy from the speaker to the vicinity of a person's ear. The wave guide comprises an elongated wall structure having inlet and outlet end portions and a varying cross-sectional area that varies in a uniform and repeating manner between maximum and minimum values. This elongated wave guide with its varying cross-sectional areas forms an acoustical low-pass filter that efficiently transmits and propagates low frequencies, that is frequencies in the range of 300 Hz to 3,000 Hz.

Abstract: A novel method and apparatus are described for reducing the effect that magnetic field emissions from a radio telephone may have on devices sensitive to time-varying magnetic fields. The variance of the magnetic field is smoothed by the addition of a smoothing capacitor having a time constant significantly longer than the TDMA time frame which is connected in parallel with the transmitter. In addition, a counter-balancing magnetic field is generated by a field canceling loop connected in series with the transmitter which causes current to flow in a path approximately opposite from the path the current flows through the battery, in roughly parallel plane. The current flowing through the field canceling loop generates a magnetic field approximately coaxial with, and opposite in polarity from, the magnetic field generated by current flowing through the battery, partially negating the latter.

Abstract: The present invention provides a method for synchronizing transaction identifiers used by two mobile stations in a mobile communication system. A network station determines the transaction identifier used by each mobile station and sends a signalling message to each mobile station containing a counterpart transaction identifier element. The counterpart transaction identifier element which is sent to each mobile station contains the transaction identifier value which is used by the other mobile station to identify the connection. The counterpart transaction identifier is received and stored in each mobile station. When a signalling message containing a transaction identifier is sent from one mobile station to another, the mobile station inserts the counterpart transaction identifier rather than its own transaction identifier into the outgoing message. In this way, the receiving mobile station will recognize the signalling message as belonging to the connection.

Abstract: A modular floor tile has a two piece construction including a top member and a support member. The top member is made of a relatively hard material that is resistant to scuffing and which accepts paints. The support member is made of a resilient, impact-absorbing material and is secured to the underside of the top member. The material of the support member is selected to give the desired impact-absorbing characteristics. In a preferred embodiment, a plurality of support nodes extend downward from a bottom surface of the support member. The support nodes are spaced from one another so as to define an air circulation space between the bottom surface of the support member and the underlying support surface. The modular floor tiles also include interlocking members for interlocking adjacent tiles with one another.

Abstract: The present invention relates to a quick-recognition visual notification system for use in telephonic communication devices. Identification data, such as device ownership or the nature of the incoming communication, is communicated to and easily recognized by the owner or user of the device by utilizing the electronic circuitry of the device to assign distinct color-codes to identification data therein. The color-codes are then displayed on indicia, integral with the housing of the device, which indicates the nature of the identification data to the owner or user. Thus, the owner or user may quickly and easily identify their own telephonic communication device and the incoming communication, even at a distance away from the location of the device.

Abstract: A collapsible bag includes a base and an upper frame. A series of support rods are interconnected between the upper frame and the base. To secure the support rods within the golf bag, there is provided a retainer about the base that receives a slideable retaining cap. The slideable retaining cap is inserted within the retainer and engages a respective support rod that projects through an opening in the base. Thus the support rods are retained within the golf bag by the retaining caps that are inserted within the retainers.
