Abstract: A flat display device has a control arrangement (38) which is held by a frame (18). The frame is connected to the front plate (11) of the display device via a spring arrangement (39, 40, 37). In contrast, an arrangement having cathode wires (25) is mounted on the trough (12) of the device. If the trough is placed on the front plate, contact springs (44) on a contact strip (43) on the said frame of the control arrangement make contact with contacts on a mating contact strip (46) on the trough. In consequence, contact can be made with the control arrangement with a single-piece trough, although the latter is mounted on the front plate. Since the control arrangement is connected to a stable frame, it can be mounted in the interior of the display device in a versatile manner. <IMAGE>

Abstract: An electrical stimulation lead incorporating an electrode assembly (10) which dispenses a drug (50) adjacent the stimulation site. The lead is provided with a fixation helix (17) located at the distal end of the lead. An electrode (14) may be extended distally within the helix (17). When extended, the electrode (14) serves as a guard against perforation or other damage to tissue by the helix (17). In its retracted position, the electrode (14) is located roughly adjacent the distal end of the lead body, and lies against the tissue to be stimulated. Advancing and retraction of the electrode is accomplished by means of a stylet (24) which is removably engageable with the proximal end of the electrode (14). In one embodiment, the stylet (24) functions to both advance and retract the electrode (14). In an alternative embodiment, the stylet (24) is used only to advance the electrode (14), and retraction of the electrode (14) is accomplished by a resilient conductor.

Abstract: A switching circuit for varying rotational speed of a motor includes a power supply line (10) for connecting the motor (M) to a power source (E) so as to supply driving power to the motor. A parallel connecting circuit of an on-off switch (SW2) and a short circuiting switch (SW3) is provided in the power supply line, in such a manner that the driving power is continuously supplied to the motor when the short circuiting switch is on, while in the case that the short circuiting switch is off, the driving power is supplied to the motor during on of the on-off switch but is not supplied during off of the on-off switch. A control member (VR1) is provided for operation by an operator for varying rotational speed of the motor. The control member is operative for turning on the short circuiting switch at the maximum amount of its operation. The switching circuit further includes output means for producing an output signal corresponding to the amount of operation of the control member, a continuously conductive switch (SW3) to be continuously kept on when the control member is operated between the maximum amount of operation and the amount slightly smaller than the maximum amount, and control means connected to the output means and the continuously conductive switch for controlling the on-off switch (SW2). The control means is operative to continuously keep the on-off switch on during the time when the continuously conductive switch is on, and is operative to increase the ratio of the time during which the on-off switch is on to a unit period of cycle based on the output signal from the output means as the amount of operation of the control member increases.

Abstract: The transmitter (12) for a direct-sequence spread-spectrum communication system encodes its code rate into the phase difference between a pair of identically modulated, sum and difference frequency carriers which it transmits to the receiver (13). The receiver, in turn, mixes the two carriers with each other to recover a signal having a frequency representing their phase difference, thereby enabling the receiver to derive a synchronous code rate from the phase difference signal, directly or by means of a resettable oscillator which is driven by the phase difference signal. If desired, the sum and difference frequency carriers may have overlapping sidebands in the frequency domain.

Abstract: An apparatus for stepless control of electric loads by the phase-angle principle includes a semiconductor switch element with main electrodes. A trigger circuit furnishes turn-on pulses for triggering the switch element and includes a detector for the polarity of an instantaneous value of an alternating voltage to be switched, a turn-on pulse pregenerator circuit for furnishing turn-on pulse suggestions, a switch and driver unit, and a decision stage. The decision stage may allow or prevent the turn-on pulse suggestions to be switched through to the switch element, as a function of whether an output signal of the detector has changed its polarity between two of the turn-on pulse suggestions. The decision stage may furnish a blocking signal at least at one input for preventing the turn-on pulse suggestions from being switched through to the switch element, upon the appearance of two turn-on pulse suggestions within one half-wave of the alternating voltage to be switched and in the absence of a turn-on pulse suggestion during one entire half-wave of the alternating voltage to be switched. For brightness control, a transformer has a secondary winding connected to an incandescent bulb and a primary winding connected to one pole of an alternating voltage source and to one main electrode, while another pole of the voltage source is connected to another main electrode.

Abstract: A pixel assignment and error diffusion system and method of gray scale printing in one or more color planes in the fields of ink jet printing, electrophotographic printing, or the like. The direction of each error diffusion with respect to (28) the location of a just-scanned or just-processed super pixel (28) within a larger scanned area is controlled by the contemporaneously developing gray scale profile and gradient over a previously scanned area defined by a predetermined number of previously scanned super pixels (28-44). This developing gray scale (116, 118, 120, 122) profile and gradient of a scanned image is used to select a matching error diffusion set (E) of diffusion points, each having a relative weight W and a location L, from a chosen look-up table stored in memory (98). The relative weight W is proportional to the gray level intensity of the developing profile (116, 118, 120, 122) and the location L is proportional to the slope of the gradient of a family of gray level profile or contour lines (104, 108, 112), wherein the gradient is generally perpendicular to these lines. The selected error diffusion set (E) is in turn used to control the direction and weighted distribution of an error remainder value R into areas of a processed image adjacent each just-scanned or just-processed super pixel (28-44) within a larger scanned area.
