Abstract: A simplified structure is disclosed for a dual-band, double-conversion superheterodyne receiver. All mixer-injection signals are generated by combining the outputs of two phase-locked frequency synthesizers driven by a single reference oscillator. The output of one synthesizer injects the receiver's second mixer, which converts signals from the first intermediate frequency to the second intermediate frequency. The output of the other synthesizer has two uses: (1) it provides first mixer injection needed to tune the receiver to a primary band, and (2) it is mixed with the output of the first synthesizer to provide the first mixer injection needed to tune the receiver to an alternate band.

Abstract: The present invention comprises a wastewater treatment process wherein the waste activated sludge is digested to produce treated biosolids which are then directed to a dewatering facility that removes water from the treated biosolids. Before or during the dewatering process, both a low molecular weight polymer and a high molecular weight polymer are added to the treated biosolids. The addition of the two polymers of different molecular weights results in the treated biosolids coagulating and then forming flocs of biosolids that effectively drives water from the flocs and renders the flocs more susceptible to an efficient and effective dewatering process.
Abstract: The present invention provides a fuel dispenser system capable of receiving a signal from a vehicle transponder. Upon receiving the transponder's signal, the dispenser determines the proximity of the vehicle relative to the dispenser, and preferably, a particular fueling position associated with that dispenser. Proximity is determined by measuring one or more characteristics of the signal received at an antenna associated with the dispenser. Generally, the strength or magnitude of the signal received at the antenna is the characteristic used to determine vehicle proximity. Multiple directionally sensitive antennas are used to correlate a vehicle at a unique fueling position. The controller is configured to receive a signal from the transponder indicative of the presence of an ORVR system on the vehicle. Depending on the sophistication of the communication link between the transponder and dispenser, the dispenser will control its vapor recovery system accordingly.
Abstract: A warp knit, weft inserted fabric substrate for use as a strength component in vinyl coated and laminated backlit signs, awnings and in other applications where stability and uniform geometry is desired. The stable knit construction of the fabric is achieved by doubling the number of stitches or courses per inch of fabric. To avoid changing the industry-wide standard fabric construction of 18x12 with the stitch doubling, weft yarns are inserted every other stitch. In a fabric having an 18 x 12 construction, the number of stitches doubles from 12 to 24. The final fabric construction is 18 warp ends per inch, 12 weft ends per inch, and 24 courses per inch. Although the course count increases from 12 to 24 stitches per inch, only one weft yarn is inserted for every two stitches rather than every stitch as currently done in the prior art. By doubling the number of stitches through shortening the stitch length, the weft or filling yarns area forced to remain in a restricted are of the fabric.

Preferably, the dispenser is provided with a swivellable wheel.
Abstract: A fractional loading scheme is used to improve the spectral efficiency of a cellular system, and therefore increase the number of users that the system can support. The fractional loading scheme allows only a fraction of the total number of available communication channels within each cell to be used simultaneously. Thus, each cell is deliberately underloaded to operate at less than its full capacity. The underloading of the individual cells reduces the spectral efficiency within each cell. However, the underloading of each cell means that there will be fewer interfering users at any given time so that the co-channel interference is reduced. This reduction in co-channel interference allows the reuse distance between co-channel cells to be reduced thereby increasing the reuse of frequencies throughout the system resulting in an increase in spectral efficiency in the system as a whole.

Abstract: A system and method for funding a home investment trust program to provide for home mortgage payments to pay for a home throughout the mortgage period, a first trust fund and a cash-out amount payable during the mortgage period useable for college expenses, and a second trust fund payable at the end of the mortgage period for retirement, wherein funding for the trust comes substantially from income tax savings associated with deducting interest paid on a home mortgage. The invention includes determining the purchaser's tax liability and any tax refund or reduction due to the deduction attributable to interest paid on the home mortgage. The latter amount is systematically deposited into a trust fund. At a point during the mortgage period, the home maybe refinanced in a manner allowing the homeowner to "cash-out" part of the equity build-up. After refinancing, the homeowner will continue funding another trust with income tax deductions attributable to the interest paid on the home mortgage.

Abstract: The present invention relates to a method for transmitting multiresolution image data via wireless devices in a radio frequency communication system wherein images are decomposed into levels of resolution. The image data is stored in discrete information blocks in an image storage unit including a base image and one or more image details. The base image represents the coarsest resolution of the image. Each image detail, when added to the base image, improves the resolution of the image. An image display unit transmits a request for image data to the image storage unit. In response to the initial request, the base image is transmitted to the image display unit. If the base image is insufficient, the resolution can be increased incrementally by sending additional image data requests to transmit additional image detail. The additional image detail is then transmitted to the image display unit and recombined with the base image to provide a higher level of resolution to the image.
Abstract: A battery pack for an electronic device including a latch assembly comprising a latching member, a biasing member, and an actuator. The latching member is movable between an extended position and a retracted position. The biasing member urges the latching member to the extended position so that when the battery pack is mounted to the electronic device, the latching member prevents its removal. To remove the battery pack, an actuator is provided to engage the latching member and push it downwardly to a retracted position. During assembly of the battery pack, the latching member can be pushed down to a retracted position allowing the actuator to move to an assembly position. In this position, the actuator is engaged by a retaining member on the battery case to hold the latching member and actuator in place during assembly.
