    • Systems and techniques for cleaning a corona discharge point are described. A controller (150) can be operatively coupled to a corona discharge point (108) to control the operation of the corona discharge point (1089. The controller (150) and the corona discharge point (108) can be included with, for example, an ion mobility spectrometry (IMS) system (100). The controller (150) can be used to operate the corona discharge point (108) at an operating voltage for a first time interval, with or without an additional higher pulse voltage, to produce a corona discharge, and to operate the corona discharge point (108) at a cleaning voltage greater than the operating voltage for a second time interval subsequent to the first time interval to produce a corona discharge. The effectiveness of the corona discharge point (108) can be monitored by, for instance, measuring a voltage necessary to produce a corona discharge at the corona discharge point (108), measuring a current produced at the corona discharge point (108) from a corona discharge, and so forth.

    • A method of using a telecommunications network cashless transaction service is provided, in which a user accesses the service using a network access instrument, such as a mobile phone which produces a signal. The signal is forwarded to an interface device of the network, which extracts service and user identity data therefrom, and passes the data to a processing unit for the service of the network. The service processing unit processes the data, instructs the interface device to forward the access instrument signal to an input output device of the network, and instructs the input output device to request transaction details from the user. The details are sent to the input output device, which passes them to the service processing unit which processes the details and decides whether or not the transaction can proceed, causes output of a signal conveying acceptance or rejection of the transaction to the user, and, if the transaction can proceed, arranges for the transaction to be carried out. The telecommunications network may comprise a fixed network, the interface device may be a service switching point, the service processing unit may be a service control point, and the input output device may be an interactive/intelligent voice recognition unit.

    • An apparatus includes a sample receiving port and an inlet assembly configured to be positioned adjacent to the sample receiving port. The inlet assembly defines a volume for receiving a sample and includes a gap that defines an extraction port. The extraction port is configured to extract one fluid flow to facilitate another fluid flow toward the sample receiving port. The extraction port can be configured as an annular flow port around the sample receiving port. In some instances, the apparatus also includes a curtain port positioned apart from the sample receiving port and the extraction port. The curtain port can be used to guide fluid away from interior surfaces of the inlet assembly and toward the sample receiving port, and/or to provide an environment of controlled air, and/or to isolate the sample receiving port from external sources of contamination.
