  • Patent number: 10247162
    Abstract: A starter system for start up of a combined heat and power unit comprising a generator which is connectable to the grid. The starter system comprises a variable frequency drive, VFD, operable to receive power from the grid. The VFD reduces the frequency of the power, and provides the reduced-frequency power to the generator to start the generator. The starter system further comprises a bypass relay configured to bypass the VFD. The bypass relay allows direct connection between the grid and the generator after the generator has started. The variable frequency drive is configured to operate temporarily during start up of the combined heat and power unit.

    Abstract: In one embodiment there is provided an aquatic toy configured for movement under water. The aquatic toy employs sensors to automatically turn on when placed in water and further employs a timing circuit to automatically turn the toy off after a predetermined amount of time. The aquatic toy further includes a shock sensor to monitor movement of the toy when in water and after the timer expires. Movement such as tapping on the tank, splashing the water, or physical movement of the toy will turn on the toy and re-activate the timer.

    Abstract: A vehicle proximity annunciator device reduces an occurrence of a pop noise without an additional circuit changing an output of a power amplifier. A capacitor is located between a connection point connecting multiple resistances generating a reference voltage and a ground terminal. The capacitor causes a rise-up time of the reference voltage to delay at a start of power supply to a power source terminal. A sound emission signal is increased at substantially a same level of the reference voltage so that a variation of a differential voltage between the reference voltage and the sound emission signal falls in a pre-determined range.

  • Patent number: 7210656
    Abstract: A model train operating, sound and control system that provides a user with increased operating realism. A novel remote control communication capability between the user and the model trains. This feature is accomplished by using a handheld remote control on which various commands may be entered, and a Track Interface Unit that retrieves and processes the commands. The Track Interface Unit converts the commands to modulated signals in the form of data bit sequences (preferably spread spectrum signals) which are sent down the track rails. The model train picks up the modulated signals, retrieves the entered command, and executes it through use of a processor and associated control and driver circuitry. A speed control circuit located inside the model train that is capable of continuously monitoring the operating speed of the train and making adjustments to a motor drive circuit, as well as a novel smoke unit.

  • Patent number: 7188703
    Abstract: In a device for establishing noise in a motor vehicle, including a housing having an inlet space, which is in communication via an inlet line with a gas-carrying part of an internal combustion engine arranged in the motor vehicle, and an outlet space, which is acoustically coupled by means of an outlet line to an interior space of the vehicle or the space surrounding the vehicle, the inlet space is separated from the outlet space at least by an acoustically substantially inactive wall. Arranged inside the housing is a sound transmission device, which has vibratable elements, one arranged in the inlet space and onother arranged in the outlet space and connected to each other by a curved connecting element, which is mounted on the acoustically inactive wall, for the transmission of sounds introduced through the inlet line into the inlet space to the outlet space.

  • Patent number: 7042340
    Abstract: An animal alerting device system and method for mounting in a vehicle produces a sound that stimulates an alertness response in large animals to reduce the likelihood that the animals will run into a roadway and cause an animal-vehicle crash. The sound produced by the device is a random sound pattern in an audible frequency range. The volume of the sound produced is automatically adjusted for vehicle speed. Different sound patterns may be produced automatically based on different geographical locations of the vehicle in which the device is mounted.

  • Patent number: 7006001
    Abstract: A speech or phrase emitting celebration device, in the nature of a piñata, includes a longitudinal axial channel within which is placed a complementally sized integrated circuit (“IC”) including a library of pre-programmed voice chips having phrases selected by random. The circuit is responsive to impacts or shocks upon a fanciful housing of the device sufficient to actuate a shock sensor switch thereof. A speaker, in electrical communication with the circuit board of the integrated circuit, is in mechanical communication with a speaker at an end of the channel so that the emitted phrase may be heard by those in the vicinity of the device. A hollow cylindrical sensor may be disposed within the interior channel to provide appropriate input to the shock sensor switch, or a more sensitive discrete element sensor may be used.

  • Patent number: 6819234
    Abstract: Method and system for providing an audible warning of approach of a moving vehicle that is undergoing hard braking. When hard braking is being applied and the initial vehicle velocity (just before hard braking is first applied) is at least equal to a selected threshold velocity, an artificially produced warning sound, resembling the screech or howl of one or more tires in a panic stop, is transmitted, in one or more selected angular sectors. If the initial vehicle velocity is less than the threshold velocity, the warning sound is witheld. The threshold velocity may depend upon one or more of initial velocity, initial deceleration, local road surface conditions and local weather conditions.

  • Patent number: 6750759
    Abstract: When a dividing ratio data is written in a counter/timer register 530, a counter/timer circuit 534 divides a frequency of an oscillation signal of the oscillator 532 as much as the dividing ratio data. When an output enabling data is written in the port B register 536, a variable gain control signal is output from an envelope producing circuit 538. A variable gain control circuit 540 changes amplitude of a dividing signal as much as the value responsive to a voltage of the variable gain control signal. When an output disabling data is written in the port B register 536, the variable gain control signal is not output from the envelope producing circuit 538. The variable gain control circuit 540 stops the amplitude control of the dividing signal.
