Abstract: A facsimile system which produces variable resolution and size images on a reproduction medium is disclosed. A timing means produces two signals which control resolution in a first direction. The first signal controls release of pixels from a memory buffer to modulate the beam intensity of a cathode ray tube while the second signal controls the sweep in the first direction of the electron beam of the CRT. Resolution and size in a second direction is controlled by repeating lines of image data until the desired resolution is achieved. Hardware savings in the facsimile can be achieved by connecting a direct memory access controller to a graphics microprocessor through the host post of the graphics microprocessor and by using alternating banks of memory for storage of image data.

Abstract: A security system provides for bidirectional communication between a controller and a plurality of addressable transponders. At least one transponder includes a sensor circuit for detecting motion, which motion is indicated by the transponder signalling back to the controller. During a walk test the controller sends a signal back to the transponder, completing the circuit for the visible output indicator so that subsequent motions during the walk test sequence will be immediately displayed at the transponder, without necessitating successive communication through the loop including the controller. In systems where the controller itself reports upwardly in a hierarchy of units, the walk test can confirm operability of the entire system, including other condition-indicating signals.

Abstract: The invention is an improved level indicating and elevation indicating system using a hose containing fluid having a first and a second end, capable of being operated by a single person. An electronic method is used to indicate when a float at the first end of the hose is at, above, or below a reference. In the preferred embodiment, such indications are communicated through wires to three distinct lights at the second end of the hose, and a sight is used to determine accurately the position of a float at the second end. The preferred embodiment also includes a sleeve supporting the first end of the hose and a support for the sleeve. Also included are a vertical fixed rod for supporting the second end of the hose, a base for holding the fixed rod in virtually any position, and an adjustable rod (parallel to the fixed rod) for determining vertical offset distances. A pinching device, for slightly varying the volume of the hose, is also part of the preferred embodiment.

Abstract: A communication system (200) includes a portable radio (100) which has environmental detection capabilities. The radio (100) upon detecting the presence of an environmental condition such as smoke above a predetermined threshold, transmits an information signal to a communication station (202). Once the signal is received by communication station (202), it is decoded and a message is annunciated. The communication station (202) can transmit a message to radio (100) in response to the information signal. Optionally, before radio (100) transmits an information signal to the communication station (202), it first determines if the environmental condition (e.g. smoke) has been detected for a predetermined period of time.

Abstract: A fault indicator for indicating the occurrence of a fault current in a monitored conductor includes an electrostatically-actuated indicator assembly. During normal operation a lightweight indicator flag rotatably mounted in and viewable from the exterior of the indicator housing is held in a reset-indicating position by electrostatic force resulting from an electric field existing between the flag and adjacent electrodes. Upon occurrence of a fault current in the monitored conductor the electric field is removed and the indicator flag, under the influence of a permanent magnet, is caused to rotate to a fault-indicating position. By avoiding the use of magnetic actuator windings and associated pole pieces the indicator assembly is easier and more economical to construct.

Abstract: An illumination output from a fluorescent lamp used in a RIS type scanner is maintained at optimum by monitoring the lamp's on/off state and turning the lamp on for a time period following a specified cumulative off time. In one example, the lamp is turned on for a two minute interval following a one hour off time. Following the two minute on period, a diagnostic test is automatically performed to determine whether variations in the lamp output have resulted in an out of specification condition requiring that the lamp be recalibrated to the photosensor array. The calibration is automatically enabled by adjusting the gain of the photosensor array until the photosensor response is within the nominal percentage range. The scanner is then returned to a standby mode. All of the tests are performed automatically and normal operations can be accomplished while the lamp is in warm up phase.

Abstract: A foldable electronic print board copies or records, on recording paper, various patterns of information, including letters, numerals, images, etc., which have been handwritten on a writing sheet. The foldable electronic print board has a pair of hinged cases housing the writing sheet, and a printer for printing the handwritten information on the recording paper. The printer is detachably mounted on the cases across the axis about which the print board is foldable, to keep the print board unfolded. Since the printer itself is used to hold the print board unfolded, no dedicated holder or holders are required to be fixed to the cases. The printer is located at the geometric center of the print board for thereby making the print board stable in use.

Abstract: The present invention relates to an improved solid-state imaging device having pixel amplifiers. The higher definition of the device results in the increase in number of pixels as large as not less than two million. When a solid-state imaging device having such a large number of pixels is provided with pixel amplifiers, there arise various problems associated with a power source and a power supply line as well as a problem inherent to the pixel amplifier type of solid-state imaging device. The present invention provides a solid-state imaging device in which noises or the like are prevented and a picture or image quality having high definition can be obtained, by suppressing a voltage drop of the power supply line and by compensating fluctuations in outputs of the pixel amplifiers.

Abstract: An image sensor is operable in a read state, a rest state, and a stand-by state. Control signal generating means generate a control signal. The control signal has a first constant preset level during the read state, a second preset level during the rest state, and alternates between the first and second levels at a duty ratio during the stand-by state. Drive circuit means transfer current to the image sensor in response to the control signal. Therefore, current is continuously transferred to the image sensor during the read state, no current is transferred during the rest state, and current is intermittently transferred to the image sensor at the duty ratio during the stand-by state.

Abstract: A remote monitoring apparatus comprises a computer program controlled monitor for detecting changes in condition responsive relay switches to generate a data signal identifying the change of switch condition, a report assembler which prepares a report in a preselected format identifying the apparatus location and including the data signal generated, and a modem for automatically transmitting the assembled report to a selected number of remote locations connected with the monitoring site by a telecommunication network. The monitoring apparatus repeatedly accesses the telecommunication network until a successful communication has been transmitted to each remote location. The apparatus also senses the loss of a continuous, primary power source and includes a back-up power supply. The program limits the number of unsuccessful attempts which can be made with the back-up power supply and preserves the assembled reports for later transmission when power has been fully restored.
