摘要： An obstruction detection circuit for detecting an obstruction of a sample probe of an automated sample aspiration/dispensation device and a method for detecting such an obstruction. In one embodiment the obstruction detection circuit includes a pressure sensor measuring the pressure in a fluid conduit connecting a pump and the sample probe orifice. The pressure within the connecting fluid conduit is measured by the pressure sensor shortly after the start of the aspiration or dispensation of a fluid volume by the automated sample aspiration/dispensation device. The pressure within the connecting fluid conduit is again measured after the completion of the aspiration or dispensation, and if the pressure has not returned to a predetermined range within a predetermined amount of time, an error condition is reported.

摘要： Apparatus and methods for vaporizing LNG while producing sufficient volume of compressed natural gas at sufficient pressure to meet the needs of internal combustion engines, gas turbines, or other high consumption devices operating on natural gas or on a mixture of diesel and natural gas. The LNG vaporizer of the present invention incorporates a reciprocating pump to provide vaporized LNG to an output at rates and pressures as required by the particular application. The heat rejected into the engine coolant and the exhaust stream from an artificially loaded internal combustion engine, as well as the hydraulic heat resulting from artificially loading the engine, is transferred to the LNG as the LNG passes through a heat exchanger. Exhaust heat is transferred to the engine coolant after the coolant passes through the heat exchanger.

摘要： A liquid supply module includes one or more sets of bulk liquid containers each supplying a respective reservoir via a liquid supply line. The bulk liquid containers and reservoirs are vented above the highest liquid level in the system. A pump periodically removes a known volume of liquid from a reservoir which is replenished from a bulk liquid container. A sensor detects a liquid/air transition in the liquid supply line to the reservoir indicative of the exhaustion of liquid resupply from the bulk liquid container. Art air vent solenoid valve in communication with the reservoir is closed when an empty bulk liquid container is replaced. Normal pump operation siphons liquid out of the bulk container after container replacement. A control system tracks pump iterations and calculates a number of executable iterations remaining before the reservoir runs dry. With a fresh bulk container in place, the air vent solenoid opens the reservoir air vent upon detection of an air/liquid transition allowing liquid to flow by gravity from the bulk container into the reservoir. A bulk liquid container lid sensor indicates whether a bulk liquid container is properly installed in the system. The liquid module is disposable in a sliding drawer, and can include unique mechanical keying means to insure each bulk liquid container fits in only one position in the liquid supply module.

摘要： A unity gain buffer is provided. The unity gain buffer includes two complementary pairs of emitter followers and two bias current sources. The top bias current source is arranged to provide a bias current so that, if the input voltage is greater than zero, the bias current provided by the top current source increases at the input voltage increases. The bottom current source is arranged to provide a bias current so that, if the input voltage is less than zero, the bias current provided by the bottom current source decreases as the input voltage decreases.

摘要： In a continuously variable transmission with a toroidal variator including an input shaft supporting spaced outer toroidal disks, a hollow transmission shaft through which the input shaft extends and which supports inner toroidal disks between the outer toroidal disks axially spaced from the inner toroidal disks so as to form chambers therebetween, the hollow transmission shaft is supported via bearing supports which radially extend into at least one chamber of the toroidal variator and form bearing points resulting in a shortened axial overall length of the transmission as compared with transmissions having conventional bearing arrangements and also in an improved support structure.

摘要： A medical device detachment system receives an elongate delivery member, having a lumen, and an elongate core member. The system includes a housing, a user input mechanism for receiving a user input to effect detachment of a medical device, such as an embolic coil, from a distal end of the delivery member, and a grasping mechanism for grasping and moving a proximal end of the core member relative to a proximal end of the delivery member. The system also includes a first sensor detecting positioning of the proximal end of the core member within the housing, and a second sensor, detecting movement of the grasping mechanism. An indicator is connected to the first and second proximity sensors and provides feedback to a user.
