摘要： A position detecting and control system for a vehicle includes a low frequency transmitter and associated antenna and a receiver and associated antenna, one of the antennas being mounted on the vehicle so the distance between the antenna carried by the vehicle and the other antenna is determined by the amplitude of the signal induced in the receiving antenna. The frequency of the transmitter is such that the distances to be monitored are a small fraction of the wavelength of the frequency involved, and any significant signal variations due to signal reflections which can reinforce or cancel the received signal are avoided. The system monitors at least two different spacings between the transmitting and receiving antennas where the signals received at the receiving antenna are of widely different orders of magnitude. Separate range detecting circuits are coupled to a common point of the receiver, each of which includes an attenuator at the input thereof for adjusting the level of the signal to be fed to an associated signal level detector which operates a control device when the signal at the receiver output point involved reaches a level indicating the associated spacing to be monitored.

摘要： An antenna internally contained within a housing of a cordless telephone is configured generally as a plate disposed opposite the earphone transducer, and away from the user's face in position for normal use. The antenna is disposed to lie generally vertically, and is counterpoised against a generally vertically disposed circuit board. Configuring the antenna generally as a plate and placing it outboard away from the user's face minimizes detuning effects during normal handling in use. Optional side extensions to the plate increase the antenna capacitance. An optional counterpoising shield may be interposed between the receiver-transducer and the antenna plate to further minimize detuning effects. Mode switches are disposed in a position on the handset remote from the antenna to further minimize detuning effects during switching operations. A similar antenna may be disposed within the cordless telephone base unit with the antenna disposed remote from the surface on which the base unit is mounted, and further having its associated mode switch disposed at a location remote from the antenna so as to minimize detuning effects from proximity to metallic surfaces and mode switching.

摘要： An electrical controller, such as a controller timer for a home lighting circut, is connected so that a power switch like a triac controlled thereby replaces a conventional toggle switch operating in conjunction with another toggle switch in series therewith which can operate the controller. The timer is continuously coupled to the AC power system by permanent connections between the movable pole of the remaining toggle switch station and the load terminal of the triac of the controller and the power system. A stationary contact of the switch forms a control signal terminal which extends to a control input terminal of the controller. The controller may also include a depressible pushbutton or other on-off control switch which when successively operated generates pulses which toggle a control circuit to alternately render the triac conductive and non-conductive, and to program a controller-timer. The controller includes a voltage change pulser circuit whose input is coupled through the control input terminal of the timer to the stationary control contact of the single-pole switch, and which preferably generates the identical signal as is generated by depression of the pushbutton, when the signal condition on the stationary control contact either changes from a no-signal to a signal condition, or from a signal to a no-signal condition.

摘要： A timer system includes a power switch operable to power circuit closing and opening conditions, timing means for identifying various timing segments over a 24-hour period and marker storage means having respective power turn on and off marker storage locations assigned to the time intervals encompassing a 24-hour period. An on-off push button or other on-off control operates the power switch and may act as an aid in setting the markers in the storage means. The timer system may also include a rotatable present time setting dial, also adjustable to different positions representing the different time intervals, and a manually operable timer on-off setting member. For real time programming, control means respond to normal operation of the on-off control during a first 24-hour period, initially to set said markers in the storage locations. For fast programming, the control means responds to the successive advancement of said dial from a present time setting through said various positions and the selective operation of the push button or other on-off control to set the markers in the storage locations assigned to the time interval involved, which markers automatically control the operation of the power switch when the timer on-off setting member is in its timer-on position, except when overriden by operation of the on-off control.

摘要： A transistor test circuit provides for the selection of preferably three widely differing test frequencies for testing transistors normally having respectively relatively small, intermediate and large frequency gain-bandwidth product characteristics. These test frequencies are each much greater than the assumed normal cut-off frequency of the transistors to be tested thereby, and preferably only a fraction of the frequency at which the current gain of normal transistors would decrease to one. The test circuit is designed to form a linear amplifier circuit with the transistor under test and is provided with an automatic base drive control circuit which provides a substantially fixed predetermined DC collector current, despite wide variations in the current gain between different transistors being tested. The circuit further includes an indicating means for displaying the product of the selected test frequency and the current gain of the transistor under test, as indicated by the amplitude of the amplified test frequency signal in the collector circuit of the transistor under test.

摘要： The circuit includes sources of periodic, low duty cycle, load terminal energizing and control terminal driving pulse waveforms. During each cycle, the waveforms occur only during successive test intervals occupying only a small portion of each cycle. During each test interval a load terminal energizing pulse is generated to energize a transistor or FET device of a different conductivity type and a control terminal drive voltage is penetrated which initially is of a polarity which would render a transistor or FET device of the associated conductivity type non-conductive, and then switches to a voltage of opposite polarity to render such device fully conductive. There is provided means for selectively varying the control terminal driving current which flows in an operating device from a relatively high to a relatively low level. Signals are derived showing the transition in the conductive states of the devices under test during the polarity transition of the control terminal drive voltage waveform. A first detecting and storage circuit is provided which detects and stores the occurrence of a current transition during the first test interval showing a possibly properly operating device of one conductivity type, and a second detecting and storage circuit is provided which detects and stores the occurrences of a current transition during the second test interval showing a possibly properly operating device of the opposite conductivity type. The storage circuit sets a leakage and material type test voltage producing circuit to produce a test voltage of proper polarity, depending upon whether the possibly properly operating device is of one or the other conductivity type.

摘要： The emission of the various electron guns of a color cathode ray tube are measured and indicated preferably by a time sharing multiplexing technique where bright intensity producing emission generating voltages are fed between th cathode and control or accelerator electrodes of the various electron guns preferably in rapidly repeated sequence. The switching rate is preferably many times per second so the emission current values are displayed as steady indications on the faces of current meters with meter movements which respond to the average emission curent of the associated electron gun. A quick and convenient means for determining whether or not the ratio of the highest and lowest emission measurements fall within an acceptable range is provided by means which proportionately reduce the conduction periods of the electron guns, so the highest or lowest emission measurement falls along one margin of a band on the scale of the associated meter face whose opposite margin is at a value which indicates the limit of an acceptable highest to lowest emission ratio.

摘要： One form of the timer is designed to be mounted over and behind a conventional wall switch cover plate and includes a two position timer condition-setting arm, a rotatable and depressible time setting dial knob and an indicator on the front of the cover plate. When the arm is moved to a timer-on position, the indicator flashes to indicate that timer programming is needed. This may be achieved in real time over the first twenty-four hours after a 30 minute play period by depressing the knob acting as an on and off power switch control push button to turn the light circuit on and off in a normal manner. Fast normal programming is achieved by rotating the knob to various time settings and depressing the knob to set ON or OFF markers in timer memory. A full twenty-four hour programming is completed by either completing a full rotation of the knob over the full twenty-four hour time settings, with at least one ON and one OFF depression, or by a similar pair of knob depressions without such a full rotation, OFF markers then being automatically set by the timer to complete the timer programming. The indicator comes steady-on to indicate that the timer is fully programmed and in an automatic mode of operation. The automatic operation is temporarily overridden by depression of the knob or permanently overridden by a simple distinctive speed or time duration depression of the knob.
