Abstract: An improved mass spectrometer is set forth. The mass spectrometer comprises an ion injector that is configured to provide a plurality of ions for analysis and an ion selection unit that is adapted to receive the plurality of ions from the ion injector and provide only those ions having a selected mass-to-charge ratio for detection/analysis. The ion selection unit includes an outer electrode and a plurality of inner electrodes. The plurality of ions provided by the ion injector are accepted into the interstitial region between the outer electrode and the plurality of inner electrodes. A power supply system is connected to the electrodes of the ion selection chamber. The power supply system is adapted to provide an oscillating voltage to at least one of the plurality of inner electrodes to facilitate separation of ions of the selected mass-to-charge ratio from ions of non-selected mass-to-charge ratios.

Abstract: An apparatus for providing television audio programming that is derived from a broadcast television signal is set forth. The apparatus includes a transceiver that is adapted to selectively receive one of a plurality of broadcast television signals in response to a channel selection signal received at a channel selection input thereof. The transceiver converts the audio signal component of the television signal to a radio signal for reception by a radio receiver. The radio receiver, in turn, converts the radio signal to an audible audio signal corresponding to the television audio programming. The apparatus also includes a control module formed as a unit that is physically distinct from the transceiver. The control module includes a programmable microcontroller, a user interface connected to provide at least channel selection information to the programmable controller, and a display connected for control by the programmable microcontroller to indicate at least channel selection information to a user.

Abstract: An improved mass analyzer is set forth. In accordance with one embodiment, the mass analyzer employs a unique mass filter design that comprises an ion selection chamber in which ions are selected for detection based on their mass-to-charge ratio (m/Q) by subjecting them to a non-rotating, oscillating electric field that, ignoring any fringing effects, oscillates principally in a single coordinate plane (i.e., the y-z plane). The ions may be injected into the ion selection chamber at a significant angle with respect to the inlet of the chamber and in the single coordinate plane to raise the m/Q resolution to the desired level. In accordance with a further embodiment of the mass analyzer, an ion detection surface is arranged at the outlet of the ion selection chamber so that ions falling within a predetermined exit angle range are detected to the general exclusion of ions having other exit angles.

Abstract: An improved mass analyzer capable of parallel processing one or more analytes is set fourth. The mass analyzer comprises a mass filter unit having a plurality of ion selection chambers disposed in parallel with one another. Each of the plurality of ion selection chambers respectively includes an ion inlet lying in an inlet plane and an ion outlet lying in an outlet plane. The mass analyzer further includes a plurality of electrodes disposed in the ion selection chambers and at least one RF signal generator connected to the plurality of electrodes to produce a non-rotating, oscillating electric field in each ion selection chambers. A plurality of ion injectors are each coupled to inject an ion beam into the ion inlet of a respective ion selection chambers. The ions meeting predetermined m/Q requirements pass through the ion selection chambers to contact corresponding detection surfaces of an ion detector array.
