摘要： The present disclosure generally relates to uroflowmeters and methods for processing data generated therefrom. In one aspect, the uroflowmeter is a handheld device. The uroflowmeter includes a handle, a flow chamber coupled to the handle, and a sensor associated with the flow chamber that detects a parameter of urine received in the flow chamber. The uroflowmeter may include both reusable and disposable components. As a uroflowmeter it can identify and record data corresponding to the rate of flow over the measured duration of a void of urine, but may also timestamp the voiding act and communicate the data to an external data collection center for additional analysis and incorporation into a comprehensive voiding report or voiding diary.

摘要： A cap for a fluid sensor is provided. The cap comprises a cap input port including a first toolless connector configured to removably couple to a cable; and a cap output port including a second toolless connector configured to removably couple to a cable. The cap may further comprise an interface circuit including a circuit input port, a circuit output port, and a sensor port configured to couple to the fluid sensor. The first toolless connector may be configured to removably couple the circuit input port to a cable and the second toolless connector may be configured to removably couple the circuit output port to a cable. The circuit will automatically sequence the signals on the cable, so standard one-to-one wired cables can be used.

摘要： A capacitive sensor assembly for determining a fluid level within a fluid reservoir sensing through impedance change due to capacitive element driven by radio frequency differential voltage source. The chip is supplied with a pair of voltage sources having opposite phases and similar magnitude, a resultant capacitance changes being represented as a changing voltage output via a capacitive voltage divider arrangement. A feedback loop with an LC circuit is also applied to the received voltages maintains the same value to compensate for measuring different fluid with the same sensor configuration or aging/acidization changes in the dielectric constant of the oil as it ages.

摘要： An electric wave type biosensor includes: an electromagnetic wave irradiation unit; and a reflected wave receiving unit which receives a reflected wave and obtains an I signal obtained by multiplying the irradiated electromagnetic wave signal and the received reflected signal, and a Q signal obtained by delaying the I signal only by a predetermined phase. The electric wave type biosensor further includes: a differentiation calculation unit which differentiates the I signal and the Q signal and calculates an I signal differential value and a Q signal differential value; and an angular velocity calculation unit which calculates an angular velocity of the I signal and the Q signal, based on the I signal and the Q signal and the I signal differential value and the Q signal differential value.

摘要： An apparatus and method estimate fluid mass in a cryogenic tank that holds a multiphase fluid comprising a liquid and a vapor. The apparatus comprises a level sensor, a pressure sensor and a computer. The level sensor provides a parameter representative of a level of the liquid. The pressure sensor provides a pressure signal representative of vapor pressure inside the cryogenic tank. The computer is operatively connected with the level sensor and the pressure sensor to receive the parameter and the pressure signal, and is programmed to determine the level from inputs comprising the parameter, to calculate a first volume of the liquid from inputs comprising the level, and to calculate a first mass of the liquid from inputs comprising the first volume and the pressure signal.

摘要： A liquid level transducer (10) for mounting to a cryogenic tank includes a mounting head assembly (14) for connection to the tank (12) and an elongate sensing probe assembly (16) extending from the mounting head assembly (14) and into the tank. The mounting head assembly (14) has a lower mounting member (40) connected to the sensing probe assembly (16). The mounting head assembly also includes a tank mounting member (42) with a central bore (74) and a transverse wall (87) located within the bore. An upper connecting section (60) of the member (40) is threaded into the bore (74). A seal (147) is positioned between the transverse wall (87) and the upper connecting section (60). The upper connecting section (60) has a corrugated feature that receives and deforms the seal to interlock the components together and increase the sealing surface area therebetween.
