摘要： A data entry terminal for storing a plurality of user generated answers is described which includes a removable volatile read/write memory module. The memory module is used to store formatting information used to configure the data entry terminal as appropriate for a particular set of questions. The memory module can for example store a set of correct answers as well as a set of user answers for each of the questions of the test, and it can store data used to disable certain functions of the data entry terminal, such as the ability of a user to revise an initially entered answer. The data entry terminal operates to record user answers in the portable memory module, which can then be removed from the data entry terminal and applied as an input to an external computer for analyzing user responses. The portable memory module includes a battery for powering a volatile semiconductor memory included in the module. The semiconductor memory is shielded against static discharge, and one of the chip enable terminals of the memory is coupled to a capacitor to prevent momentary voltage transients from changing the contents of the memory in an uncontrolled fashion.

摘要： A motor controller for a battery-powered electric motor automatically disables the motor when the battery voltage (1) remains below a first, higher level for a longer time when the motor is off, or (2) remains below a second, lower level for a longer time when the motor is on, or (3) falls below a low level less than about one quarter the nominal level of the voltage for a shorter time. The motor is automatically enabled when the battery voltage rises to a higher level for a preset time period, indicative of charging of the battery.

摘要： A monitoring unit for remotely monitoring liquid levels in a container includes a common probe, a reference probe, and four sensing probes, each mounted to the container in electrical contact with liquid within the container. A liquid level sensing unit measures resistance between the common probe and the reference probe and uses the measured resistance as a threshold to determine which of the sensing probes is in contact with liquid in the container. In this way, the sensing unit is made substantially independent of the resistivity of the liquid in the container. The sensing unit is connected to an evaluating unit by a single conductor, and the sensing unit draws a variable amount of current through the conductor in accordance with the number of sensing probes in contact with liquid in the container. The conductor thus supplies power to the sensing unit and also transmits information from the sensing unit to the evaluating unit. The evaluating unit includes a current-to-voltage converter which generates voltage proportional to the current drawn by the sensing unit. A display circuit displays an indication of the resulting voltage.

摘要： A game apparatus is disclosed having a one-dimensional array of LED's which are sequentially activated in first and second sweep sequences which proceed toward first and second goal indicators, respectively. First and second buttons are provided which operate to reverse the first and second sequences, respectively, and the object of the game is for each player to operate his button before the appropriate sweep sequence causes his goal indicator to be activated. The rate of each sweep is variable and a player can select a higher sweep rate for his opponent by delaying his reaction until a relatively later time in the sweep sequence. The score is displayed on the same indicators as are used to play the game, and successively higher scores correspond in sequence to the sequence in which the indicators are activated during play.

摘要： A door opener for a roll-type door in a cargo van includes a shaft that is mounted for rotation within the cargo van body and is coupled with the door such that shaft rotation causes the door to move between opened and closed positions. The shaft is rotated by a motor that is mounted outside of the cargo van body and is coupled to the rotatable shaft by a drive system that extends through the cargo van body. This arrangement allows a relatively large conventional motor to be used without extending into the door opening or compromising the height of the door opening.

摘要： A power management system for a recreational vehicle operates automatically to disconnect a major electrical appliance, such as an air conditioner, heater or water heater, from power when the current drawn by additional appliances exceeds a preset current threshold. When the current drawn by these additional appliances falls below the threshold, the major appliance is automatically reconnected. A preferred embodiment of this invention operates to alternate between two or more air conditioners, heaters, or the like, to ensure that only one is connected to power at any given time, but that both are activated alternately and in sequence to provide efficient use of both air conditioners. In addition, preferred embodiments of this invention operate to interrupt operation of the air conditioners whenever the power voltage falls excessively low, and to ensure at least a preselected time delay between the time an air conditioner is stopped and restarted.

摘要： An intravenous set is described which includes a housing which defines three separate chambers: an uppermost valve chamber, an intermediate volumetric chamber, and a lowermost drip chamber. The valve chamber is provided with an externally actuated structure for interrupting the flow of fluids into the volumetric chamber. In alternate embodiments, this valve member can include a magnetically responsive element, a diaphragm, or a pinch tube. A volumetric chamber is provided with a predetermined volume and is adapted for remote sensing of the fluid level inside the volumetric chamber. Fluids pass from the volumetric chamber into the drip chamber where they are formed into individual drops. The drip chamber is adapted to allow remote detection of drop formation and drop counting. A controller is described which, when used in conjunction with the described intravenous set, provides extremely accurately controlled rates of infusion.
