A navigation method for a navigating apparatus of a moving device, including obtaining weight information that includes a plurality of weight coefficients and storing the weight information, detecting one or a plurality of paths through which the moving device is capable of moving, acquiring information regarding a position of a destination with respect to the moving device as destination positional information, acquiring information regarding characteristics of topography in surroundings of the moving device as topographical characteristics information, calculating worth correlation information regarding the one or plurality of detected paths to the destination using the acquired destination positional information, the acquired topographical characteristics information and the stored weight information, and estimating a worth score of each of the one or plurality of paths to the destination based on the calculated worth correlation information.

A product state display system operates so that a person who looks at a pseudo living matter can easily understand the state of an industrial product at first glance in the case where the state of the product is represented by displaying the pseudo living matter. The pseudo living matter displayed on a display device shows both the 'aging state' corresponding to the 'progress state of time-dependent deterioration' of the industrial product within an endurance period and the facial expression corresponding to a &#x201c;temporary state&#x201d; of the industrial product. Accordingly, it is possible for a person who looks at the pseudo living matter to quickly and easily understand two states (progress state and temporary state) of the industrial product with just one glance.

A user information input structure that inputs user information, a memory structure that stores user's bearing information as robot's bearing pattern, and a regenerating structure that regenerates the pattern based on the information input to the user information input structure. A behavior selection and determination structure for selecting and deciding behaviors based on user information, a user information recognition structure for recognizing a user, a memory structure for storing the recognized user information, a calculating structure for comparing the recognized user information with the stored user information to calculate user recognition, and a compensating structure for compensating a selection and determination method in the behavior selection and determination structure in accordance with the calculated user recognition. An actuator for driving a robot, a detection structure for detecting user information and environment information, a feelings generation structure for generating artificial feelings for a robot based on the detecting user and environment information, and a behavior determination structure for determining behaviors by the robot based on the generated artificial feelings, wherein the behavior determination structure controls the actuator so that a resistance acted on the robot may be changed on tactile information the user has applied to the robot.

User-machine interface system for enhanced interaction

A control method for controlling operation of an object used by a user in an environment includes the steps of: defining pseudo-emotions of the object for deciding output of the object, in relation to the user's state; formulating emotion generation algorithms to establish the relationship between the user's state and the pseudo-emotions; formulating behavior decision algorithms to establish the relationship between input, including the pseudo-emotions, and the behavior of the object; detecting the user's state; generating a pseudo-emotion of the object based on the user's state using the emotion generation algorithms; making the object behave based on the user's state and the pseudo-emotion using the behavior decision algorithms; evaluating reaction of the user in response to the behavior of the object; and if the reaction of the user does not match the pseudo-emotion of the object in the emotion generation algorithms, adjusting at least either of the emotion generation algorithms or the behavior decision algorithms, followed by learning the adjustment. The object can detect the user's state in a visual, tactile, and auditory manner as do humans, and can act upon generation of pseudo-emotions based thereon. Thus, natural communication between the user and the object can be performed, i.e., more human like communication can be established.

Environment adaptive control of pseudo-emotion generating machine by repeatedly updating and adjusting at least either of emotion generation and behavior decision algorithms

A system guides a user (or a vehicle ) in reference to a target position via sound changes. The system (i) virtually disposes a sound source at the target position defined in a geographical data field covering the positional arrangement of the user and the target object, and (ii) actually outputs simulated sounds to the user as if the target position emitted sounds and the sounds were propagated from the target position to the user at the current position. The sounds change as the user moves in the geographical data field. For example, sound propagation paths, through which sound waves from the sound source are propagated to the user while being influenced by other objects or obstacles, are calculated based on positional data from a position detection system . Simulated sounds expressed by combining directly transmitted waves, diffraction waves, and reflection waves, which arrive at the user through the sound propagation paths, are generated, and the generated sounds are outputted from multiple speakers to in such a way that the three-dimensional position of the sound source can be identified.

A detection structure for detecting user information and environment information, a feelings generation structure for generating artificial feelings for a robot based on the detecting user and environment information, and a behavior determination structure for the behavior determination structure controls the actuator so that a resistance acted on the robot is changed.

A lubricating system for an engine and particularly for a two cycle crankcase compression internal combustion engine wherein the amount of lubricant supplied by a reciprocating pump to the engine is varied by selectively delivering lubricant to the engine and bypassing lubricant from the pump back to the inlet side of the pump. The total amount of lubricant supplied is controlled by setting a duty ratio at the beginning of a control cycle and varying the time of the control in response to engine condition sensed during the control cycle so as to provide good transient control.

Engine-driven equipment includes a stopped-engine detector and a mechanism for safely shutting down the engine, including battery operated auxiliary devices, after detection that the engine has stopped. The engine may be shut down simply by closing a gas cock in the fuel line, but whatever the cause of engine stoppage, auxiliary devices are permitted to run for a predetermined time after stoppage to, for example, cool the engine or maintain warm glow plugs for easier restarting. If the gas cock is used to stop the engine, the engine will continue to run until fuel remaining in the fuel line has been expended, and then safely and automatically shut-down.

A small portable generator powered by a gas fueled internal combustion engine. The gas fuel supply system for the engine includes a solenoid value whose duty cycle is regulated so as to permit unthrottled operation of the engine and afford engine speed control.

Gas engine

A fuel supply and glow plug arrangement for a portable electrical power supply fueled by a gaseous fuel internal combustion engine. The gaseous fuel flow to the engine is controlled by a solenoid valve having its duty cycle varied to vary engine speed. In addition, the solenoid valve is shut off when the engine speed falls below a predetermined speed so as to prevent fuel leakage. The engine is fired by a flow plug which is supplied with power at a high power level during cranking and at a lower power level during running.
