    Abstract: A method and apparatus for a networked irrigation system include a battery powered networked irrigation controller that communicates with a backend server. The backend server monitor rainfall at the location of the irrigation controllers via third party weather resources. General irrigation is set to commence once every several days, and when rain falls at the location of an irrigation controller, the watering schedule is shifted to ensure that watering does not occur more frequently than desired. The irrigation controller uses a cellular transceiver modem to communicate with the backend server, and since the irrigation controller is battery powered, the cellular transceiver modem is maintained in an off state until just prior to commencing a scheduled watering, when the irrigation controller contacts the backend server.

    Abstract: A sprinkling or irrigation system includes a sprinkler controller that is capable of detecting a leak in one or more zones of the system. The system include a main valve and an adjustable valve in a bypass line around the main valve. The adjustable valve is set to a partially closed state such that a selected on of the zones produces a pressure at a selected proportion of the static pressure provided by the water source such as half the static pressure. A leak is detected when a zone, with the main valve closed and the adjustable valve in the partially closed state, produced a test pressure that is substantially lower than the selected proportion of the static pressure, as modified by a test factor.

    Abstract: A video time-shifting system characterized in having a continuous recording track accessed by separate, asychronous read and write facilities enables playback of a video program to commence from any point in the program while continuing to be recorded in real time, thus providing VCR-like program control features such as PAUSE/RESUME, REWIND, and FAST FORWARD. A memory is used to store information relating to various points in the program so that even upon receipt of multiple PAUSE commands, the system automatically keeps track of correct program re-entry. In the preferred embodiment, the storage means takes the form of a continuous recording track in a magnetic disk drive. To prevent discontinuities associated with the recording and reproducing of material representative of the video program, the system preferably incorporates a plurality of write heads, each associated with a different recording track, and the system automatically switches from one write head to another so as to effectively link the different recording tracks into a single, continuous recording track. Although program information may be stored in analog form, digital storage is used in the preferred embodiment along with data compression to increase recording capacity. The system preferably further includes a video display generator to output for viewing on the display device visual indicia relating to the program and, additionally, symbols relating to one or more points in the program and/or the time-shifted version thereof.

    Abstract: A system for programming the automatic operation of a video recorder over an extended time period uses an associated television receiver as a display device for alphanumeric messages to the operator to provide a self-explanatory, interactive programming routine. The video recorder system includes a digital memory, a real time digital clock, and an alphanumeric character generator, all connected to a central digital controller. A keypad allows the operator to initiate a programming routine in which previously stored programming messages are called up from memory and generated on the TV receiver's display tube using the character generator. The operator's responses entered via the keypad are stored in the memory and are called up at future times to generate control signals for the video recorder. The video recorder system further includes a memory storing digital data representing a schedule of programming available for a future period. The video system permits this schedule to be recalled and displayed on the TV receiver for review by the user.

    Abstract: In a television viewing system, a VCR adapted for use with a source of cable TV, a remotely controllable cable box and a remotely controllable TV receiver provides means to determine all channels tunable by the various tuners, including pay channels. A memory disposed within the VCR stores operative control codes for the cable box and TV. The VCR incorporates switches adapted to interconnect the various components in a variety of configurations. The VCR also incorporates an infrared transmitter operative to transmit control signals to the cable box and TV receiver. Upon receipt of user inputs specifying the desired mode of operation, a controller within the VCR adjusts the switching positions to achieve an optimum configuration for the system components to perform user selections options and transmits remote control codes to the cable box and the TV receiver to place them in condition to enable the user command.

    Abstract: In a video cassette recorder (VCR) adapted for use in conjunction with a television (TV) receiver, a audio signal generator is used to produce an audio signal in response to key closures made on the VCR's remote unit with the TV speaker being used as an audio output device. In an alternative embodiment, the audio generator is in the form of a speech synthesizer which generates a human-voice message in response to commands entered via the keypad. The main VCR housing may alternatively come equipped with its own speaker, obviating the need to feed the audio signals to the TV.

    Abstract: A video recorder, adapted to receive descrambled signals from a remotely controllable tuner/descrambler for multi-channel cable or satellite signals for recording or provision to a T.V. receiver, includes a future program memory which may be programmed by an operator to cause the system to record a predetermined channel at a predetermined future time. To ensure that the descrambler is tuned to the proper channel when a signal requiring descrambling is to be recorded, the video recorder is connected to a remote control transmitter which is energized at the time occurrence of a program to be recorded to send a signal to the remote control receiver of the tuner/descrambler causing it to select the appropriate channel for descrambling.

    Abstract: The present invention is a technique for forming a signal representing the operator adjustment of a potentiometer. This technique consists of measuring the reference time constant of the resistance between the fixed terminals of the potentiometer and a capacitor, measuring the variable time constant of the resistance of potentiometer between a fixed terminal and the terminal variable by an operator setting and this same capacitor, and again measuring the reference time constant of the resistance between the fixed terminals of the potentiometer and the capacitor. These time constant measurements are made by discharging the capacitor, charging the capacitor through the appropriate terminal of the potentiometer and measuring the time required for the voltage across the capacitor to reach a predetermined threshold level. This measurement sequence is repeated if the two measures of the reference time constant differ by more than a predetermined amount. The digital ratio of the variable time constant and the reference time constant is then calculated. This digital ratio is the representation of the operator adjustment of said potentiometer.

    Abstract: The present invention is a control range display for an electronic thermostat. A plurality of individually actuable display segments are disposed in a line. Each of these display segments represents a particular temperature. The control range of the electronic thermostat is displayed by actuating the display segments representing the upper and lower preselected temperatures and all display segments therebetween. In the preferred embodiment each of these display segments is a liquid crystal display device. The preferred embodiment enables indication of the present temperature by actuation of a single display segment representing that temperature upon selection of a normal mode and an indication of the control temperature range by actuating display segments in the manner noted above upon selection of a program mode. The preferred embodiment further includes a removable mask containing a temperature scale indicia marked in a preselected geared measurement which can be disposed beside the line of display segments of the display means, thereby indicating the particular temperature represented by each display segment in the preselected unit of measurement.
