    摘要： A dual band radio is constructed using a primary and secondary transceiver. The primary transceiver is a complete radio that is operational in a stand alone configuration. The secondary transceiver is a not a complete radio and is configured to re-use components such as fine gain control and fine frequency stepping of the primary transceiver to produce operational frequencies of the secondary transceiver. The primary transceiver acts like an intermediate frequency device for the secondary transceiver. Switches are utilized to divert signals to/from the primary transceiver from/to the secondary transceiver. The switches are also configured to act as gain control devices. Antennas are selected using either wideband or narrowband antenna switches that are configured as a diode bridge having high impedance at operational frequencies on control lines that bias the diodes.

    摘要： A concrete vibrator for a hopper which feeds concrete to a slip form is mounted to the outer surface of the hopper wall. The vibrator is fixed to the end of a tube which extends into the hopper through a hole in the hopper wall. A rubber isolator molded on the tube is clamped between flanges one of which is welded to the outer surface of the hopper wall.

    摘要： A method for maintaining an accurate channel estimate. The method includes providing a reference channel estimate based on at least one long training symbol, and generating a frequency domain representation of a first data symbol including a plurality of pilots. The method then includes tracking phase change in the plurality of pilots of the first data symbol relative to pilots of the at least one long training symbol to produce correction factors, and adjusting the reference channel estimate based upon the correction factors.

    摘要： An internet based method of facilitating commerce between shippers and carriers includes the steps of capturing electronic shipment requests for available shipments, the shipment requests including shipment specific criteria and carrier access criteria, and storing the electronic shipment requests in a database. The electronic shipment requests are presented for action to the remote carriers meeting the carrier access criteria. These remote carriers may reply to the shipment requests with fulfillment offers, which are responsive to the presented shipment requests. Carrier fulfillment offers are received and presented to the remote shippers originating the electronic shipment requests. An Internet based system for implementing the method of the present invention is also disclosed.
