Abstract: In some examples, an apparatus can include a syringe body including an electrical interface at a side surface of the syringe body, an interface at an end of the syringe body including an output at a distal surface of the syringe body, a print material particles reservoir located in the syringe body, and a structure to adapt a volume of the print material particles reservoir to move print material particles out of the print material particles reservoir through the output, where in response to the volume adapting structure moving from a first position to a second position, a signal is transmitted by the electrical interface.

Abstract: A system and method for obtaining real time down hole flow measurements and proppant concentrations between perforations and/or perforation clusters during hydraulic fracturing in multistage stimulated wells.

Abstract: A regulator for in-line modulation of the flow rate of fluid during blood collection includes a fluid transfer device for transferring fluid from a patient to a collection device. The fluid transfer device comprises a fluid passageway defined by a tubular sidewall and a flexible member associated with a portion of the tubular sidewall. The flexible member is configured for movement with respect to the fluid passageway upon exposure of the fluid transfer device to a differential pressure during a blood collection procedure to prevent collapse of a patients blood vessel. The flexible member of the regulator can be a frame surrounding a flexible diaphragm. Alternatively, the flexible member can include a flexible material integrally formed within the tubular sidewall of the pressure regulator.

Abstract: Example apparatus, methods, and systems are described for performing bottom hole measurements in a downhole environment. In an example system, a bridge plug is deployed at a downhole location of a cased well, An optical fiber cable is deployed exterior to the casing of the well. The bridge plug includes a sensor and an acoustic signal generator, which transmits acoustic signals through the casing to the optical fiber cable.

Abstract: A regulator for modulation of the flow rate of blood out of a patient's blood vessel during blood collection is disclosed. The regulator includes a housing having a housing inlet, a housing outlet, and a wall defining a housing interior. At least a portion of the wall includes a flexible member. A valve is associated with the flexible member and is in communication with the housing interior. The regulator is designed so that upon an application of a differential pressure within the housing interior, the flexible member and/or valve automatically move with respect to either the housing inlet or housing outlet to modulate a flow of blood moving through the housing. A manual over-ride device can be provided to enable a user to over-ride the automatic regulation and manually regulate the flow of blood through the housing.

Abstract: In accordance with the teachings of the present invention, a method is presented for displaying power and heat faults that occur in a network. A server initiates a variety of power alarm display methods. Each method is directed at receiving specific types of power alarm information and displaying or inhibiting the display of this information on a wallboard. The methods operate simultaneously and update the wallboard with power alarm information in near real time. Further, the methods continue to operate and update the display of the power alarm information when tickets associated with the alarms are received or when an operator acknowledges the alarm.
