Abstract:
The present application generally relates to a public address system, and more particularly, to a paging relay controller within the public address system and methods thereof. In an illustrative embodiment, the paging relay is configured through a dynamic host configuration protocol server. After configuration, the paging relay can process incoming network streams. The paging relay can receive an incoming network stream from a source typically in the form of a unicast stream. The stream can be transported over a wide area network that commonly does not support multicast transmissions. After receiving the unicast stream, the paging relay converts the unicast stream into a multicast stream. The paging relay then rebroadcasts the multicast stream over a local area network to local subscribing devices. In one embodiment, the paging relay can also convert the unicast stream to line level audio for transmission to an analog system via the RCA phono port.
Abstract:
A device for displaying advertisements has a plate member. An opening is formed in the plate member, wherein the opening is sized to fit a display screen of a desired dimension. Support arms are coupled to the plate member for securing the device to a storage device to which the device is installed.
Abstract:
A valve rod guide is adapted to be coupled to the barrel of a subsurface pump or the like. The guide has head, neck, body, and base regions. A plurality of angled flutes are provided on the body, tapering downwardly for preventing solids from reentering the pump barrel after pump operations are ceased and thereby damaging pump components once pump operations are resumed. The interior diameter of the neck includes lower and upper grooves and a plurality of spiral radial grooves extending therebetween. The spiral radial grooves terminate at exit ports. During pump operations, solids are wiped from the valve rod, drawn into the spiral radial grooves, and accumulate in the lower or upper groove during downstroke or upstroke, respectively. During upstroke, the solids are expelled through the exit ports. A hardened insert may be positioned in the head region, providing a durable wear area for the valve rod as well as a tight fit, thereby preventing solids from escaping through a northern end of the guide.
Abstract:
A pump apparatus includes a gear pump assembly interposed between top and bottom drive gear assemblies, and coupler assemblies interposed between a bottom of the top drive gear assembly and a top of the gear pump assembly, and between a top of the bottom drive gear assembly and a bottom of the gear pump assembly. The drive assemblies rotate a pre-feed auger. A cyclone screen located within a cyclone housing is positioned over a shaft of the pre-feed auger and interposed between a blade of the pre-feed auger and the bottom drive gear assembly. An intake housing is positioned over the blade of the pre-feed auger, and regulates fluid intake into the pump.
Abstract:
A remote advertising system and method are provided. The advertising media (such as video, pictures, audio and text) may be stored on computer servers. The advertising media is downloaded to one or more kiosks at scheduled intervals and displayed on a rotating schedule. Users may interact with the advertisement to request additional information relating to the advertisement to be displayed, purchase the advertised products and services, or print out tickets, coupons or the like for related or unrelated products and services.
Abstract:
A method of enhancing the flavor of food by exposing the food to acoustic waves from a low frequency sonic transducer immersed in liquid is provided. The liquid may be the food itself and/or the food may be positioned within a range between about ¼ inch and about 20 feet from the liquid-containing container, and is preferably exposed to waves at a frequency ranging between about 1 Hertz to about 1000 Hertz, optimally 600 Hz for approximately one minute to 24 hours, optimally about 30 minutes. The acoustically-treated food is also provided.
Abstract:
A computer system comprising a processor for executing program instructions and a memory coupled to the processor for storing the program instructions, the programming instructions comprising: enter intake data on a patient; entering symptoms the patient is experiencing and services performed on the patient, wherein all symptom and services listed in the program instructions are assigned a numeric number based on severity of the symptom and service; calculating total value of all numeric values of symptoms patient is experiencing and services performed on the patient; and making a recommendation to one of continue hospital stay or discharge of the patient.
Abstract:
A system and method for performing cost analysis on airplane schedule interruptions comprises entering data relating to schedule interrupt events. All schedule interrupt events for a specified period of time are then summarized. Partial schedule interrupt event counts are removed when calculating average delay hours associated with a particular schedule interrupt event grouping. An average total delay cost per schedule interrupt event type is calculated wherein the partial schedule interrupt event counts are used in the calculation of average total delay cost per schedule interrupt event type.
Abstract:
A circuit for generating a high voltage alternating current to drive a load has a current source having a first terminal and a second terminal. The circuit further has an output terminal and a circuit ground terminal. A first switch will conduct between the first terminal of the current source and the circuit ground terminal when the first switch is closed. A second switch will conduct between the first terminal of the current source and the output terminal when the second switch is closed. A third switch will conduct between the second terminal of the current source and the circuit ground terminal when the third switch is closed. A fourth switch will conduct between the second terminal of the current source and the output terminal when the fourth switch is closed. A load is coupled to the output terminal and the circuit ground terminal.
