Abstract: A straddle-type personal snow vehicle includes a body frame, an engine, a front support and a rear track drive mechanism that is driven by the engine. The front support may be a front suspension that supports at least one front ski. The rear track drive mechanism may be supported by a rear suspension that may include multiple linkage members. In one arrangement, the track drive mechanism includes a drive wheel and at least a first support wheel. An axis of rotation of the first support wheel is positioned forward of an axis of rotation of the drive wheel. In one arrangement, the at least one front ski is coupled to the front suspension by a tool-less attachment mechanism.

Abstract: Behavior of a device is modified based on the device's experience. The device comprises: (i) a sensing unit for sensing signals; (ii) an interest-generating unit programmed to generate interest-parameters in response to the sensed signals; (iii) an emotion-generating unit programmed to generate emotion-parameters in response to the sensed signals; and (iv) an actuating unit for actuating the device. The device collects information based on its interest and modifies its behavior when the device observes the same object as previously, based on variations of emotions generated when the device observed the object in the past.

Abstract: Behavior of a device is modified based on the device's experience. The device includes: (i) a sensing unit for sensing signals; (ii) a concern-generating unit programmed to generate concern-parameters; (iii) an emotion-generating unit programmed to generate emotion-parameters; and (iv) an actuating unit for actuating the device. When the device is in a situation, the device extracts memory relevant to the situation to obtain concern-parameters previously generated in the situation. The behavior of the device is regulated by concern-parameters in the memory and emotion-parameters generated based on the concern-parameters, and accordingly, the device can modify or improve its behavior.

Abstract: Behavior of a device is modified based on the device's experience. The device includes: (i) a sensing unit for sensing signals; (ii) a concern-generating unit programmed to generate concern-parameters; (iii) an actuating unit for actuating the device; and (iv) a memory storing a spreadsheet composed of multiple sets of data, each set corresponding to an event defined by signals received by the device, variations in its concern-parameters, and behavior of the device. When the device has variations in its concerns in a situation, the device extracts from the memory an event, if any, to best compensate for the variations to select behavior in the situation. The selected behavior may be adjusted by variations in its emotions. The behavior of the device is regulated by variations in its concerns, and the device can modify or improve its behavior based on the stored information obtained in the past.
