    摘要: A pulse width modulated (PWM) output signal controller circuit is provided for controlling operation of an electronically commutated, direct current (DC) motor. This DC motor may be used for operating cooling fans in sensitive electronic equipment. The controller circuit maintains the motor speed as constant resulting in a minimizing of the motor power consumption and resultant noise generation. Controller circuit output PWM signals are maintained at a constant pulse width even in the presence of variations in the voltage levels supplied to the controller circuit. The controller circuit includes a current pulse sensor circuit that senses changes in current direction in a motor coil. This current pulse sensor's output is input to a monostable multivibrator circuit that produces a chain of constant height output pulses (PWM signals). This multivibrator circuit output pulses are used to enable and disable a pair of Hall effect-type integrated circuit (IC) output transistors, into alternately conducting and non-conducting states, with only one output transistor conducting at a time. These output transistors are connected to power (drive) a motor coil. A Hall effect device senses the rotor's magnetic field and provides synchronization enable signal to each of the multivibrator circuit driven output transistors. The multivibrator circuit includes a connection to a variable resistor circuit whose value is used to adjust and/or set the width of the output pulses (PWM signals) provided by the multivibrator circuit. The value of the variable resistance may be manually adjusted, which adjustment alters the width of the PWM signals and thereby changes the power delivered to a motor coil. This variable resistor circuit is also automatically adjustable as a function of changes in motor speed sensed. This automatic adjustment maintains a constant width for the PWM signals even in the presence of variations in power supply voltage levels supplied to the multivibrator circuit, which otherwise would change the PWM signals generated and the resultant motor speed.

    摘要: A single device adaptable to alter any one of a variety of air characteristics such as temperature, humidity, ion content, odor, etc. Several interchangeable cartridges are provided. Each cartridge has an apertured support structure, an air treatment element that alters a particular characteristics of an air flow through the cartridge, and male connectors. The device has a housing, a fan, and female connectors that cooperate with the male connectors to position any one of the cartridges on the housing to receive an air flow discharged from the fan. When interfitted, the connectors also complete an electric circuit to a power supply that provides current to any electrically-operable cartridge. A removable protective envelope contains the cartridge. The protective envelope has an arm that inserts through a housing slot to trip a switch controlling current flow from the power supply. When the protective envelope is removed, current flow to the cartridge is disabled, allowing safe handling of the cartridge. A push-button switch extending from the bottom of the housing disables current flow to the cartridge when the device is raised or inadvertently knocked over.

    摘要: An H-type motor bridge coil driver circuit is implemented with an electronic switch in each leg segment of an H-shaped circuit, this bridge circuit having its side legs each connected between a power supply and ground, with the inductive load of a motor coil being connectable as the cross leg of the H-shaped circuit. An alternate current path, voltage level stabilizing element may be connected across each leg segment electronic switch. A coil excess energy storage element may be connected to the coil nodes of the circuit, through alternate current path elements and utilized to temporarily store the discharging of the excess coil energy normally available because of the lagging nature of the motor coil current. This temporary storage element then may discharge this energy back to the power supply through a passive circuit element, and reverse polarity protection is included for the power supply.
