A knowledge-based system and method for establishing and managing routes for emergency vehicles. The knowledge-based system and method uses a knowledge base having information useful in establishing and managing routes for emergency vehicles including information on intersections, road segments connecting intersections, expected travel time along the road segments, and dynamic factors that influence traffic flow, and a database for storing routes designed using the information useful in establishing and managing routes. The knowledge-based system also consist of one or more software modules operable to retrieve information from the knowledge base and to perform operations such as designing routes between location involved in emergency response, selecting between such routes, and modifying such routes all using information in the knowledge base.

System and method for knowledge-based emergency response

A transmitter-receiver controller system for remote actuation of devices or appliances such as security systems and garage door opener systems. The transmitter and receiver each utilize a programmable microcontroller for encoding and decoding signals. The device code, the data transmission format and the transmission frequency are selectable. The device code, data transmission format and the transmission frequency of the transmitter and/or the receiver can be selected to emulate other remote transmitter-receiver controller systems to enable operation of the present transmitter and receiver with those systems.

A trailer backup steering input apparatus is coupled to a vehicle. The trailer backup steering input apparatus comprises a rotatable control element (e.g., a knob) and a rotatable control element movement sensing device. The rotatable control element biased to an at-rest position between opposing rotational ranges of motion. The rotatable control element movement sensing device is coupled to the rotatable control element for sensing movement of the rotatable control element. The rotatable control element movement sensing device outputs a signal generated as a function of an amount of rotation of the rotatable control element with respect to the at-rest position, a rate movement of the rotatable control element, and/or a direction of movement of the rotatable control element with respect to the at-rest position.

Circuits and methods of dynamic modulation are disclosed. A dynamic modulator is used to reduce measurable conducted and/or radiated electromagnetic interference (EMI). The dynamic modulator is configured to generate either a set of optimal frequency modulation depths or discrete frequencies or both, and dynamically selects them to use over a series of programmable time durations (dwell time). Together with the utilization of Peak, Average or Quasi-Peak (QP) method of measurement, the dynamic modulator can reduce the spectral amplitude of EMI components, in particular the lower harmonics, to effectively pass regulatory requirements. In alternative embodiments, the dynamic modulator is used in a closed loop system to continuously adjust the frequency and the duty cycle of a PWM signal to reduce conducted and/or radiated EMI.

A trainable transmitter comprises a receiver, a signal generator, and a processor. The receiver receives a signal from a transmitter. The signal generator generates a signal having a frequency related to a frequency control signal supplied to a frequency control terminal of the signal generator. The processor is directly coupled to the frequency control terminal of the signal generator for supplying the frequency control signal and directly coupled to an output terminal of the signal generator for monitoring the frequency of the signal output from said signal generator.

A radio control device includes a transmitter, in which a crystal type high frequency module equipped with a high frequency circuit corresponding to a frequency band of a carrier and a PLL high frequency module equipped with the high frequency circuit and a PLL circuit for controlling a frequency of the carrier depending on a phase difference between the carrier and a reference signal of oscillator are detachably mounted. Such construction permits the crystal type high frequency module and PLL high frequency module to be selectively used as desired and transmission data to be output by means of the carrier of a desired frequency set depending on the high frequency module. Also, the radio control device includes a receiver which employs a frequency synthesizer system in which a PLL, circuit for controlling an oscillation frequency depending on a phase difference between a reference signal and the oscillation frequency is used and includes a frequency selecting means for selecting a required frequency from a plurality of predetermined frequency data and a frequency setting means for fixedly setting a receive frequency on the frequency selected by the frequency selecting means when a power supply is turned on.

A radio control transmitter capable of enhancing controllability of a remotely controlled unit, for example a model car includes a control unit having switches 8 for controlling the neutral positions of servos that operate based on control inputs of a throttle trigger 3 and a steering wheel 4, wherein the switches 8 are provided on a control unit 10 that rotatably supports the steering wheel 4, corresponding to a mount 2 a of a main body. The control unit 10 is detachably installed corresponding to the mount 2 a of the main body, while capable of being attached to a discretionary position in the direction of rotation. Accordingly, the position of the switches 8 can be adjusted to meet the needs of a user. Consequently, the user can operate the controlled unit with enhanced controllability.

PROBLEM TO BE SOLVED: To simplify the structure of this mechanism by lessening components, and to enable a stick lever to be reset automatically. SOLUTION: A rotation operating part 8 with a lever 9 to be rotated around neutral position N is fixed on the rotation axis 6 of a rheostat mounted on a cabinet 3. Two protrusions 13A and 13B are on the straight line on the side surface of the rotation operating part 8, putting the rotation axis 6 therebetween. In reset spring 10, a fixed base 10c is passed through a guide groove 16, and an engaged hole is engaged with an engaging pin 17 of the guide groove 16 to be fixed. When the lever 9 is not operated, the reset spring 10 keeps the rotation operating part 8 at the neutral position N touching the two protrusions 13A and 13B. When the lever 9 is operated to rotate the rotation operating part 8, an arm part 10b is pushed down by the protrusion 13A or 13B to be elasticity deformed. If the lever 9 is released in this state, the lever 9 is automatically reset to the neutral position N by the elastic force of the reset spring 10.

PROBLEM TO BE SOLVED: To provide a mechanism operating a pair of switches with high operability by operating both of them individually or simultaneously. SOLUTION: The shaft 10 of a switch lever 4 is rotatably supported by a long hole 11 in a housing 1. The operation part 6 of the switch lever 4 is out of the housing 1. The switch lever 4 is energized by an energizing means in the direction of an arrow 12. There are the two switches in the housing 1. Each tip of the two arms 7 and 7 correspond to each switch 2. At the time of depressing one of the switches 2, the operation part 6 of the switch lever 4 is depressed in the direction of the one of the switches 2 to rotate the switch lever 4 in the same direction by a bearing part 9. At the time of depressing the two switches 2 and 2 at the same time, the operation part 6 of the switch lever 4 is depressed downward against energizing force. The supporting shaft 10 is lowered along a shaft hole 11 to press down the whole switch lever 4 into the housing 1. Each operation parts 8 and 8 of the arms 7 and 7 of the switch lever 4 simultaneously depress the actuators 2a and 2a of the switches 2 and 2. COPYRIGHT: (C)1997,JPO
