  • Patent number: 7005066
    Abstract: A trash trap for liquid manure disposal systems that has a cylindrical housing with an open interior. The housing has a first end with an inlet port and an outlet port in its side wall. The cylindrical housing also has a removable cylindrical filter that has a fluid opening in its side walls and is detachably mounted along a centerline of the housing. The cylindrical filter has a diameter that is less than the inner diameter of the housing so that fluid can enter the housing through the inlet port and exit through the outlet port. Also, on the second end of the housing there is a detachable cap around an access opening.

  • Publication number: 20030176756
    Abstract: A method of disposing of hazardous wastes connected with criminal activity comprising transporting a portable incinerator to the site of the criminal activity, sorting through waste materials at the site and selecting waste materials which are combustible and will not emit harmful emissions. The selected waste materials are placed within the incinerator and heated to a temperature of between 1600-1900° F. Non-combustible containers used to practice the illegal activity can be sterilized at the same time. The residue from the incinerator can then be collected and buried in a non-toxic landfill.

  • Patent number: 6542486
    Abstract: A wireless telecommunications network includes a base station controller which, in turn, is comprised of a call control resource manager and a multiple technology vocoder having first and second interfaces, first and second selection managers, a vocoder controller and first, second, third, fourth and fifth resources, each embodied as a software module, for performing D/A and A/D conversions on messages configured in accordance with EVRC, EFRC, RLP, VSELP and QCELP protocols, respectively. When transferring messages between a mobile terminal and an MSC via the base station controller, the mobile terminal first informs the call control resource manager of the protocol to which the message conforms. In turn, the call control resource manager advises of the vocoder controller of the protocol type for the incoming message.

  • Patent number: 6453175
    Abstract: A wireless telecommunications network includes a base station controller which includes a call control resource manager and a multi-function coding element embodied within a DSP and comprised of first, second and third coding resources, each embodied as a software module, for respectively performing D/A and A/D on voice, facsimile and data messages. When transferring messages from a mobile terminal to an MSC via the base station controller, the mobile terminal first informs the base station controller whether the message is a voice, facsimile or data message. The mobile terminal then transfers the message to the call control resource manager residing within the base station controller. Based upon the indicated message type, the call control resource manager selects, from the first, second and third coding resources, a resource for performing a D/A conversion of the message received from the mobile terminal.

  • Patent number: 6330428
    Abstract: A voice quality performance evaluator includes an interface, memory, processing circuitry and may include a network interface. The interface is adapted to couple to a voice transmission path under test. The memory couples to the interface and is adapted to store an original voice sample and a modified voice sample. The processing circuitry couples to the interface and to the memory, retrieves the original voice sample from the memory and transmits the original voice sample to the voice transmission path under test via the interface. The processing circuitry also receives the modified voice sample via the interface from the voice transmission path under test. Finally, the processing circuitry compares the original voice sample to the modified voice sample in the frequency domain to evaluate the performance of the voice transmission path.

  • Patent number: 5339752
    Abstract: A livestock incinerator is provided, and includes a compartment or incineration chamber defined by opposite sidewalls, opposite end walls, a bottom wall, and an open top which is selectively closed by a plurality of lids pivotally connected to the walls of the incinerator. The interior of the incinerator is lined with firebricks, including all the walls and the lids. The firebricks are secured in place by a plurality of T-shaped brackets which define channels for receiving the edges of the firebricks. A primary burner is operatively connected to the incinerator for heating the chamber such that the carcasses burn to ashes. An exhaust stack is connected to one of the lids, and includes an afterburner for further combusting the products of combustion from the chamber so as to prevent atmospheric pollution. The primary burner and afterburner are operatively connected in series so that if one burner fails to operate, the other burner will automatically cease operation.
