Abstract: Multiport/multidrop computer communication is provided over a single communication facility (310) between a plurality of central stations (100,101,102) at a central location their respective remote stations (320,330,340) at remote locations. Outbound transmissions are multiplexed from a multiport central modem (300) to compatible multiport remote modems (350,351,352). The central stations (100,101,102) are monitored to detect which one or ones have invited a response from a remote station (320,330,340) and one central station is selected. A signal is sent to the remote modems (350,351,352) indicating the selected central station. The signal is combined with the request to send of the invited remote computer (500) associated with the selected central station to enable use of the return transmission lines. The request to send signal line idle or idle code stations are monitored to detect which central stations have invited a remote. Signaling is by RTS-DCD simulation in commercial modems. Another central station is selected if return transmission does not begin within a timer interval. Fast reset is provided if carrier persists after the return transmission has ended.

Abstract: A plurality of strings are extended along a surface of a body, and an operation by a player with respect to the strings is detected by two detection systems (302, 303, 304). The first detection system (205, 302) is operated when a string vibration is started, and electrically obtains an operated fret position of the string by detecting an ON/OFF operation of a switch arranged below each fret. The second detection system (110, 303, 304) is enabled after the first detection system (205, 302) is enabled, and directly measures a pitch period of the string vibration. The second detec­tion system detects (110, 303, 304) a change in pitch by a choking operation or an arming operation of a tremolo arm with respect to the string after tone generation is started.

IPC: C08J7/00
Filed: 1989-11-17
Abstract: Certain organic polymeric materials are capable of reversibly accepting or donating electrons from a reducing entity. The redox sites in the polymer accept electrons and, as a result, a change in the properties of the polymer occurs. This change is useful in modifying or etching the polymeric material. The material can be modified by incorporation of metallic seeds into the material at a controlled depth. The seeds are incorporated by interaction of cations of the metals with the redox sites in the polymer, which cause the reduction of the cations to form the neutral metallic seeds. Subsequent exposure of the polymeric material containing the seeds to an electroless bath causes further deposition of metal having the de­sirable characteristic of good adhesion to the poly­meric material. Etching of the polymeric material can be carried out as a result of an increase in solubility of the polymer in aprotic solvents when its redox sites have accepted electrons. The increased solubility allows openings to be etched in certain areas of the polymeric material that have been reduced, leaving other areas unchanged.

Abstract: A single channel optical recording system is described, which system does not require a second rotating optical element. The system uses focus error correction components located outside the rotating drum. Light transmitted to and from the drum is at all times axially symmetric, thus circumventing the problem of image rotation. Lateral error correction takes place entirely within the drum, requiring only the transmission of d.c. electrical power across the rotating interface. Preferably the physical distribution of optical components within the drum is symmetric to ensure mechanical balance. A dual beam tracking system to write data in compact form in a single-channel optical tape recorder is also described. The tracking is achieved in the drum and without any additional optical elements. Passive or active alignment of the two beams before entering the drum is achieved using an extended anamorphic prism pair and without introducing additional optical surfaces into the beam path.

Abstract: A cardiac pacemaker (10) has a sense amplifier (20) responsive to signals representative of cardiac activity for passing signal components lying in a selectively variable pass band and for selectively varying the gain of the passed signal. A pair of signal comparators (58, 59) constituting switched capacitor amplifiers, associated with the sense amplifier (20), are responsive to the filtered and gain adjusted signal for comparison of its magnitude to predetermined target levels for determination of heart rate and the need for change of rate. Two target levels are provided in each comparator (58, 59) for comparison with the level of the detected signal, by multiplexing the switched capacitors. Another switched capacitor amplifier (99) is used to develop a voltage reference level insensitive to temperature, supply voltage, and circuit components, for deriving the target levels for the comparison. Still another multiplexed switched capacitor amplifier comparator (125) is used to develop a first target level to regulate the level of the pacing stimulus, and a second target level for comparison with the supply voltage level of the pacemaker as a measure of the point at which the pacemaker requires replacement.

Abstract: An AC coupling receiver circuit for use in a communication system comprises a comparator(1) connected to transmission lines forming a twisted pair wire, through AC coupling capacitors(C1,C2),and a non-linear element(N)connected between the transmission lines at a position close to the comparator with respect to the capacitors. When positive and negative pulses are respectively applied to the transmission lines, the voltages of the transmission lines are respectively increased and decreased to bring the non-linear element to a substantially cut-off state, thus causing the comparator output to be inverted. As the positive and negative pulses decay, the comparator output is again inverted, thus effecting signal transmission. During the application of pulses, the change stored in the capacitors is quickly discharged through the non-linear element, whereby fluctuation of the received threshold voltage resulting from the stored charge can be eliminated even if pulse inputs are continuous. A high-reliability communication system can be realized by incorporating circuits which enable signal transmission even in the event of a short circuit or disconnection of the transmission lines.

Abstract: The invention provides a method for selecting the intensity level of each of the primary colors for displaying or printing a predetermined, desired color to be composed of a specified percent of each of the primary colors. Each primary color has available a predetermined number of discrete intensity levels ranging from minimum to maximum and is to be displayed on a matrix having a predetermined number of cells. The first step in the method is to determine a desired intensity level for each primary color and to select the number of cells of the matrix which are to display that color at that intensity level. These cells of each primary color are then arranged in the matrix in a predetermined ordering to display the desired color. The sequence of the ordering is predetermined and the same for each primary color. The starting point of the sequence for one of the primary colors is fixed, but the starting point for each successive primary color is dependent upon the ending cell location of the sequence of cells for the preceeding color. Using the invention, the amount of color memory required is reduced because the number of storage cells required for storage of color selection information need only be equal to the product of the numbers of available intensity levels for each primary color.

Abstract: An acrylate copolymer is made from an alkyl acrylate and a salt of 2-acrylamido-2-methylpropane sulfonic acid (AMPS). 
     The copolymer is suitable for blending with magnetic particles, e.g. of ferrite material, to make a flexible permanent type magnetic composition. The polymer can be loaded with a large amount of magnetic particles. 
     A carboxylated ethoxyl alkyl phenol surfactant may be used which provides good processability and permits a blend of the magnetic particles with the emulsion acrylate copolymer to be precipitated from a latex solution by high shear mixing. Flexible high magnetic energy magnets can thus be made and utilized in various applications such as refrigerator doors, electrical motors, and the like.
