摘要： One or more loads, commonly solenoids, requiring a high-power drive--typically 500 ma. 7.5 v.d.c.--are selectively actuated by energy that is accumulated over time--typically over several hundred milliseconds--within associated, addressable, energy-accumulating high-power drivers. The energy accumulation is solely from micropowered signals--typically 1 ma., 4.5 v.d.c.--that are received from a control system that is itself micropowered--typically from a high-equivalent-series-resistance power source. The energy-accumulating high-power solenoid drivers (i) accumulate predetermined amounts of energy only as, when, and to such extent as is required, (ii) multiply the voltage (nominally times two) of the received micropowered signals, and (iii) shape the current waveform of the output high-power solenoid drive signals--all as desired so as to optimally both use and conserve energy. The selfsame micropowered signals normally supply several energy-accumulating solenoid drivers in electrical parallel, selectively addressing an individual one such driver. Each energy-accumulating solenoid driver is tri-stated, and neither consumes nor leaks energy save imminently upon the times of its selected actuation, and of the actuation of the load that it drives.

摘要： Separate, but related, firmware programs for multiple microprocessor-controlled irrigation controllers that are interrelated in their control of irrigation within an irrigation system are generated off-line at a personal computer. The programs are downloaded into a transportable memory device that holds sixty-four separate programs. The memory device is transported to each irrigation controller and plugged to a digital communication channel. The device automatically identifies itself to the controller, and vice versa. The appropriate program is automatically uploaded from the device to the controller. The controller's old program and its historical irrigation record data is loaded into the device and delivered to the personal computer for validation and analysis. A wireless remote test command assembly, an extension maintenance panel, or a radio-link central module may be alternatively connected to the controller's digital communication channel. The controller is powered by the memory device during the uploading.

摘要： An elimination-absorber monitoring system addresses diaper-monitoring problems with a unique, low cost, multi-layer disposable sensor structure that absorbs small volumes of urine, yet allows most urine volume to flow unimpeded through it, and into the diaper below. When connected with a reusable, miniature monitor/indicator unit, the sensor presents a clear and on-going change of measurement condition upon experiencing a rapid influx into the diaper of a significant volume of urine, and/or upon a significant reduction in the available absorbency of the diaper's top surface. The sensor additionally provides recessed, protected elements for similarly presenting a clear and on-going change in measurement condition upon experiencing the presence of fecal matter. Further provided is the monitor unit employing narrow, widely-spaced, fast rise-time, fast transition-time pulses for conductivity measurement and alarm activation. The monitor and sensor are interconnected and attached to a diaper by particularly effective and unique means, and the monitor is equipped with a highly intuitive and convenient control interface, as well as improved assemblies for the transmission of audible and visual alarm indications. Also described is a convenient test-strip device which, when connected to the monitor/alarm unit of the system, can selectively simulate either a soiled or unsoiled elimination-absorber/sensor for test, caregiver-training or demonstration purposes.

摘要： A programmed irrigation controller automatically computes durations for, schedules, and controls split irrigation cycles at up to eight watering stations. The controller is manually entered with high-level information regarding soil type, terrain, and irrigation system watering head type, and also with a total irrigation time, for each station. The maximum "on" time duration for each individual split irrigation cycle, and a minimum "off" time duration, are determined from the high-level information input by table lookup. The controller computes the number of irrigation cycles at each station as its total irrigation time divided by its maximum "on" time duration. The controller schedules composite irrigation cycles for all stations so that no station overwaters within a single irrigation cycle or upon successive irrigation cycles that are too closely time proximate. Exclusionary time-of-day intervals that specify when no watering will occur can be inserted within the schedules. A water budgeting factor proportionately controls the numbers of split irrigation cycles. Special overlaid schedules provide useful special irrigation sequences/durations such as one-time deep soak, periodic deep soak, or syringe cycles. The programmed irrigation control for a single station may be copied for the control of additional stations.

摘要： An electromagnet defines a gap between a first polepiece in the shape of the butt end of an elongate cylinder and a second polepiece in the shape of a thick annular ring. A permanent magnet having its poles aligned along the axis of the cylinder moves bidirectionally in the gap in response to alternate polarity energization of the electromagnet, serving as a prime mover. When the electromagnet is not energized then the magnetic flux of the permanent magnet shunts an adjacent polepiece, holding the magnet in place. Upon energization of the electromagnet the relatiely strong magnetic flux of the permanent magnet is switched by a relatively weak electromagnetic flux to pass through the electromagnet, exerting an electromotive force on the permanent magnet and causing it to move. This flux switching offers gain: a one-half gram samarium cobalt permanent magnet moves 0.38 mm in response to a 0.015 ampere 1.5 v.d.c. 20 millisecond current pulse (4.5.times.10.sup.-4 joules) and holds at 40.+-.2g's. dislodging acceleration at each of two stable positions where no power is consumed. Back-to-back configurations of the actuator sharing a single electromagnetic coil can be operated single-ended push-pull, double-ended with non-mechanical phase or antiphase lock, and fully independently-controlled multiplexed.

摘要： A user interface, typically to an irrigation controller, prompts user responses by asking questions. The questions are hierarchally organized, preferably in a hierarchal tree having approximately three to six questions on each hierarchal level between root and leaves. All command and data input may be done with only an "OK" pushbutton switch, and with an additional ".uparw.", or ".dwnarw." pushbuttom switches. Each "OK" user response affirms the premise of a currently-displayed question, and advances the questioning to a related branch upon a next hierarchal level. The ".uparw." pushbutton is used to advance the questioning in a first direction. An optimal ".dwnarw.", or down arrow,pushbutton switch advances the presentation of successive questions in a second direction. An optional "HELP" switch invokes context-sensitive help messages.

摘要： An electronically operated primary valve actuation assembly is disclosed for use on a fluid valve in an irrigation system that can be run solely by ambient light energy. In operation, water passes from the high pressure side of a fluid valve through a filter assembly which removes particles as small as 0.002 inches. The microfilter assembly also has a magnet which further removes magnetic particles. As water exits the filter assembly it enter a microvalve actuation assembly which has two microvalves with valve inlet holes approximately 0.013 inches in diameter. It is necessary to filter the water to keep the microvalve holes from clogging. The microvalves are arranged such that when one valve is open the other valve is closed and vice versa. The microvalves require only a small amount of force to open or close the microvalve against high water pressure normally encountered in an irrigation system. Opening and closing the two microvalves causes the main fluid valve to open and close. The small force requirements to open and close the microvalves allows for use of a power efficient electromagnetic scheme for operating the microvalve. This in turn allows the fluid valves to be used in an irrigation system that is energized solely by ambient light.

摘要： An antenna of special form--to wit: a tube and more precisely a tubular dipole--is positioned inside an electrically non-conducting tubular post, typically made of fiberglass, that serves to support an electronic device, typically an irrigation controller, that communicates both by wire and by radio. Wired connection is via wires that are channeled and contained, preferably axially centrally tightly, within the tubular support post. The wires are substantially at radio frequency ground, and serve to connect the irrigation controller to one or more remote electrical devices such as soil moisture sensors and electric valves. The tubular dipole antenna is preferably formed as a fiberglass tube having a conducting exterior surface, normally made of metal and preferably copper, that is divided equally into two tubular segments. The two-segment tubular dipole antenna is located within the tubular post so that an axis of the post and an axis of the tubular surface are substantially parallel, and so that the radio-frequency ground connection wires are within both the post and the tubular dipole antenna. A shielded radio frequency feed line, preferably a coaxial cable, connects the irrigation controller in its position supported by the tubular post to the two tubular segments of the electrically-conducting tubular surface at a position between the segments. The electrically-conducting tubular surface thus serves as a tubular antenna. The directional sensitivity of the tubular antenna is substantially unaffected by the wires that are at radio frequency ground because these wires are within its interior.

摘要： A user interface, typically to an irrigation controller, prompts user responses by continuously autoscrolling questions. The questions are hierarchally organized, preferably in a hierarchal tree having approximately three to six questions on each hierarchal level between root and leaves. All command and data input may be done with only an OK/YES pushbutton switch, switches. Each OK/YES user response affirms the premise fo a currently-displayed question, and advances the autoscrolled questioning to a related branch upon a next hierarchal level. The NO pushbutton is never required to advance the questioning which is always autoscrolled, but instead serves, while depressed, to accelerate the autoscrolling of successive questions. A HELP response invokes context-sensitive help messages. A STOP response causes reversion in the hierarchy of questioning toward the root level, but does not stop the autoscrolling of questions.
