Abstract: A system and method for detecting a flow rate using ultrasound is disclosed. A flow rate detector includes a disposable conduit section and a reusable sensor chassis, the chassis configured to fit over an outer surface of the conduit section, the chassis configured to attach along a length of the of the disposable conduit section, and including first and second transducers configured to, when the reusable chassis is attached to the conduit section, measure a flow rate of a fluid passing through the conduit section by measuring an ultrasonic transmission between the first and second transducers through the fluid. The ultrasonic transmission is reflected at least once off of the inner surface of the disposable conduit before being received at the second transducer.

Abstract: A method of detecting a fault condition in an infusion process, the method includes receiving a programmed flow rate pertaining to a fluid infusion provided by an infusion device; determining, a first weight of an infusion container associated with the fluid infusion provided by the infusion device at a first time; determining a second weight of the infusion container at a second time; determining based on the first weight and the second weight, a determined flow rate of the fluid infusion provided by the infusion device between the first time and the second time. The method includes determining a difference between the determined flow rate and the programmed flow rate. When a magnitude of the difference between the determined flow rate and the programmed flow rate satisfies a predetermined threshold, by the processor: causing an output of the infusion device or the weight sensor to indicate the fault condition.

Abstract: This disclosure pertains to the use of black liquors from kraft pulp mills as a source of catalysts for the thermochemical conversion of organic matter feedstocks to bio oils.

Abstract: Embodiments are directed to eliminating false audio using an egress gateway in a communications network. At least one false audio packet is received by an egress gateway. The false audio packet includes false audio. A DTMF packet is received by the egress gateway. The DTMF packet is received subsequent to the at least one false audio packet. The false audio in the false audio packet is replaced with a substitute signal by the egress gateway.

Abstract: A method and apparatus for providing echo cancellation are disclosed. For example, the method receives via an echo canceller a first audio signal directed towards an endpoint device, and adds an inserted signal to the first audio signal directed towards the endpoint device. The method determines if a second audio signal being received from the endpoint device comprises the inserted signal, and cancels at least a portion of the second audio signal that is associated with the first audio signal, if the inserted signal is detected.

Abstract: A method of measuring a one-way packet travel time from a first communication system to a second communication system comprises receiving a Real-time Transport Control Protocol (RTCP) packet outputted by the second communication system. A Network Time Protocol (NTP) timestamp value is extracted from the RTCP packet, and a time value, T, is determined based on the NTP timestamp value. A Last Sender Report (LSR) value and a Delay since LSR (DLSR) value are extracted from the RTCP packet. A value L=T?LSR?DLSR is determined to measure the one-way packet travel time from the first communication system to the second communication system.

Abstract: An ergonomic fluid dispenser. The ergonomic fluid dispenser includes a fluid container, a dispensing assembly, and a carrying case. The ergonomic fluid dispenser allows a user to remain standing during application of the fluid.

Abstract: A system and method for reducing delay introduced by de-jitter buffers in a VoIP network is presented. The method aspect for receiving and presenting speech data received from a VoIP network comprises monitoring speech-related packets received from a packet network and based on the monitoring, either maintaining a normal speech rate, compressing the speech rate or expanding the speech rate. The speech associated with the received packets is played out (presented audible via a speaker or other means) at the normal, compressed or expanded speech rate.

Abstract: A VAD/SS system is connected to a channel of a transmission pipe. The channel provides a pathway for the transmission of energy. A method for operating a VAD/SS system includes detecting the energy on the channel, and activating or suppressing activation of the VAD/SS system depending upon the nature of the energy detected on the channel.

Abstract: An ergonomic fluid dispenser. The ergonomic fluid dispenser includes a fluid container, a dispensing assembly, an input energy/drive system, and a carrying case. The ergonomic fluid dispenser allows a user to remain standing during application of a fluid.

Abstract: A sign comprises a base layer and a transparent or translucent upper sheet over the base layer. An icon or indicia of the sign is associated with the base layer or is printed on the upper sheet. The upper sheet and base layer are releasably adhered together under pressure applied on the upper sheet which causes the icon or indicia to be displayed. When the upper sheet is released from the base layer the icon or indicia is erased. In another embodiment the icon or indicia is displayed when the upper sheet is released from the base layer, and is erased when the upper sheet is pressed to adhere to the base layer.

Abstract: An aquatic sporting device, designed for use with one arm, is formed of three removably attached sections including a paddle blade, a forearm brace, and an elongate longitudinal shaft between the blade and brace. The brace is offset both longitudinally and transversely from a proximal end of the shaft, to permit placement of the brace against the forearm at the elbow, yet permit full bending of the arm at the elbow. A hand gripping area is provided along the shaft, and enables selective gripping along the shaft length to facilitate positioning of the elbow with respect to the brace for maximum paddling leverage, regardless of the size of the forearm. When removed from one another, the sections can be conveniently stored or transported. The removable mounting further permits substitution of other working implements, such as a fish net or gaff hook, in lieu of the paddle blade.

Abstract: A computer interface for interconnecting a plurality of computer modules in a multiplex manner to emulate a computer configuration includes transmitters and receivers associated with each master and slave module, together with logic means whereby the master module is permitted to initiate computer operations with acknowledgement from the slave to insure proper data speeds. Conflicts are resolved between master modules.
