Abstract: An entertainment device is configured to receive a limited range wireless signal from at least one other entertainment device when adjacently arranged in close physical proximity to at least one other entertainment device, and to responsively operate in a first mode or a second mode based on whether the other entertainment device is adjacent a first side or second side. In the first mode, the entertainment device initiates one or more wireless activation signals to control an audio/visual element of another entertainment device. In the second mode, the entertainment device receives wireless activation signals from another entertainment device to control activation of an audio/visual element of the receiving entertainment device. Each device is interchangeable between operation in the first mode of controlling at least one other entertainment device and the second mode of being controlled by another entertainment device based on position of one entertainment device relative to the other.

Abstract: The present invention is directed to an interactive intelligent toy that provides the appearance and experience of a toy hamster moving in, and interacting with, its environment and habitat. In an exemplary embodiment, the interactive intelligent toy comprises an intelligent motive and control component enclosed by a cover resembling a hamster, with fur coat, eyes, ears, mouth, nose, and whiskers. The motive component includes a drive mechanism and circuitry operable to control the drive mechanism, monitor and detect user and event inputs, and detect and decode embedded codes from a pathway and perform predetermined actions or generate predetermined sounds in response. The motive component moves along and through a pathway component having one or more embedded codes detectable by the motive component, the embedded codes providing information to the motive component to direct desired action of the motive component.

Abstract: The present invention is directed to an interactive intelligent toy comprising an intelligent element configured to resemble a person, animal, vehicle or other character and an environmental element configured to resemble a related environment, habitat or object. The intelligent element is adapted to perform certain preprogrammed actions upon coming into contact with or proximity to the environmental element. In one embodiment, the intelligent element is a motive component having a drive mechanism, a control mechanism and power source. The motive component is programmed to monitor and detect user and event inputs, and detect and decode embedded codes from an environmental element and perform predetermined actions or generate predetermined sounds in response. The motive component also engages with a coupling component and supplies the drive mechanism and power source for moving both the motive component and the coupling component.

Abstract: An economical system and method for extracting amplitude and frequency information from a modulated AC signal are provided. In one embodiment, the invention includes a circuitry implementing op amps, a dual diode, a filter, and a comparator to receive and manipulate the modulated AC signal. The dual diode receives and splits the AC signal into two separate paths, including a baseline path and a filtering path. The AC signal passing through the baseline path remains substantially unchanged, and the AC signal passing through the filtering path passes through a low-pass filter. The signal is then sent through a comparator for comparing amplitudes of the AC signal from the two paths, and the comparator output is received by a microprocessor for controlling a display that generates a visual indicia responsive to the comparator output.
