Abstract: An inline vaporizer disposed in a carrier gas line vaporizes a fluid and adds such vaporized fluid to a carrier gas that flows within the carrier gas line. The vaporizer includes a reservoir or wick that transfers a fluid to a vaporizing element that is adjacent to the reservoir or wick. The vaporizer releases a vapor into the carrier gas line so that the carrier gas flows past the vaporizer to form a vapor and carrier gas mixture.

Abstract: A capacitor is placed in series with a solenoid to bear a substantial portion of the voltage so that a reduced voltage energizes the solenoid. The solenoid may operate a brake on a motor. Applying voltage to operate the motor, energizes the solenoid which retracts the brake.

Abstract: A selector switch in which an input obtained from a range of continuous analog signals is used to select from one of a set of discrete selections. Each selection is assigned a specified range of analog signals. Each range is separated from an adjoining range by a guard band of signals. A determination is made as to whether the input analog signal is within one of the specified ranges of analog signals. If so, a sector indicator is set to correspond to the specified range. Otherwise, the sector indicator is not changed.

Abstract: A system has a plurality of transceiver units, including a parent unit and one or more portable and wearable child units, for generating an alarm when a child transceiver unit is more than a predetermined distance away from a parent transceiver unit. The distance is determined by the difference in the phase of a reference signal from the time it is transmitted on an rf signal by a parent unit, received and retransmitted by a child unit, and then received again by the parent unit.

Abstract: The present invention provides a system for transmission loss comparison.On embodiment of the present invention compares the transmission losses through optical paths through a first solution and a second solution. This embodiment includes first and second light sources for transmitting light through the first and second solutions. Also provided are first and second light detectors corresponding to the first and second light sources, and comparison means for comparing the outputs of the two detectors in order to determine which solution is darker.In addition, this embodiment includes a common gain balance configuration means for calibrating the relative gain of the two light detectors in order to compensate for signal differences between each source/detector path arising from various mechanical or optical factors. Further included is a dark solution compensation bias to compensate for differences between each source/detector path arising from spectral differences between the two light sources.

Abstract: A system for transmission loss comparison permits enhanced accuracy over a wider dynamic range by providing a reference channel including a transmitter, receiver, and transmission path therebetween, and a sample channel, including a transmitter, receiver, and transmission path therebetween. A feedback arrangement is provided for adjusting the outputs of both of the reference and sample transmitters in relation to the signal output of the reference receiver, so as to produce a desired signal level of the reference receiver's output over a given dynamic range, so as to compensate for loss over the reference transmission path. In this way, a comparator connected to the outputs of the two receivers receives inputs that are compensated for effects of losses over the reference transmission path.

Abstract: For mounting a plurality of circuit boards each having a connecting edge with conductors adjacent thereto, one structure is provided for holding the boards parallel and a related structure for causing the boards' connecting edges to be in proximity to connectors on a mother board, with each board disposed at an oblique angle to the mother board. A preferred embodiment of the mounting device is disclosed in which the boards are plugged into a mother board having angled connectors for receiving the boards at a 45 degree angle with respect to the mother board.

Abstract: A programmable correlator correlates a sampled information signal with a programmable reference signal. The correlator utilizes a plurality of stages. Each stage includes an information register, a multiplier, and a reference register. The correlator in some embodiments permits storage in the reference registers of a series of samples of a signal related to the reference signal during the time that the sampled information signal is cascaded from one information register to the next.
