Abstract: A dual status magnetic marker for use in electronic article surveillance systems, in which a piece of low coercive force, high permeability material is positioned adjacent to a piece of remanently magnetizable material. The first piece is configured such that no characteristic response is produced when the magnetization of the entire piece is reversed by an alternating magnetic field in an interrogation zone, and when the second piece is magnetized with a predetermined pattern a localized field is provided which biases portions of the first piece, keeping those portions from reversing when the marker is in the interrogation field. The predetermined pattern is such that the remaining, unbiased portion of the first piece has a configuration capable of producing a characteristic response when the magnetization in that portion is reversed.

Abstract: An integrated data voice multiplexer (IDVM) (10) capable of simultaneously supporting loop-back and communication handshake protocols with no performance degradation can be used in both point-­to-point and packet switch networks. Frequency shift keyed FSK modulation of two or more carriers is used to send to data signal. The presence or absence of carrier signals indicates loop-back state. Narrowband modulation is selectively added to at least one carrier to support handshake protocol. The preferred narrowband modulation is biphase at a rate lower than the FSK modulation rate. The multiplexer (10) has a voice port (V) coupled through an isolator (40) to a multiplexed port (M) which is coupled to a modem (48) through transmit and receive band pass filters (42,44). A carrier phase-reversing encoder (62) controlled by a data transmit ready (DTR) signal couples the transmit output (TXO) of the modem (48) to the transmit filter (42). A remote line sense data (RLSD) signal is provided by a decoder (56) which receives the demodulated output (DMO) of the modem (48) and is controlled by output from a received signal level detector (50) and a data detector circuit (52).

Abstract: The present invention relates to an improved dual beam multichannel spectrophotomer employing a simple and novel optical system in combination with photodiode arrays and a unique logrithmic data converter to convert light signals to absorbance. In particular, the optical system utilizes optical elements in a novel arrangement to direct a pair of equivalent sample and reference beams in an essentially parallel formation respectively through a sample and reference cell and to focus and direct the emergent sample and reference beams to a single flat horizontally ruled grating which disperses each of the sample and reference beams respectively onto a pair of vertically disposed photodiode arrays whereby the light signals are converted into absorbance units (AU) by an unique logarithmic data converter. The spectrophotometer is highly accurate, has very low drift, less than 2 x 10⁻⁴ AU/°C, and very low noise, less than ±2 x 10⁻⁵AU. The dual beam multichannel spectrophotomer is particularly suitable for use in high pressure liquid chromatography to record the absorbance spectrum of the samples as they are being eluted from the chromatographic column.

Abstract: Servo positioning apparatus having a mechanism (6, 14) for positioning an object (13), for example a magnetic head in a magnetic disk recording system, and a controller (CT; 2, 3, 4, 5) for providing a servo signal ( Δ V, ΔP) derived from a position signal (PS) representing position of the object (10), for example relative to a track to be traced on a disk (10). The controller (CT; 2, 3, 4, 5) has a notch filter (32′), the notch frequency of which corresponds to a resonance of the mechanism (6, 14). 
     Components of the notch filter network, for example resistors (e.g. R₁, R₂; R₈), which can be exchanged or varied, to alter the notch frequency, are separately installed from other components, so that they may be more easily accessed or exchanged, without need to access or exchange the other components. 
     For example, the notch filter has a bridged serial T configuration with a series connection of capacitors, for example three capacitors (C₁ to C₃), with a parallel-connected resistor (R₃), and with further resistors (e.g. R₁, R₂) connected respectively to interconnection points between successive capacitors of the series. 
     Notch frequency can be altered by exchanging or varying these further resistors (e.g. R₁, R₂), which are thus the components to be separately mounted.
