Abstract: The present invention relates to induction heater control method, control device and multiple induction heater devices, the induction heating control method base on setting one of the multiple induction heater as main and the others heaters as auxiliary. The induction heater energy exchange cycle includes trigger and cut off periods, while the main heating device is in the cut off period, the auxiliary device is triggered, and while the auxiliary device is in the cut off period, the main heating device is triggered, both heating device can generate heat alternately. Using the control method and control device, multiple induction heaters can work under each other's interferences in a controlled fashion, provides more cooking options such as contact grill with heating devices facing each other while operating.

Abstract: A Data processing methods and systems adapted to manage personal health records by individuals. Wherein the patient undergoes encounters with a plurality of health care providers who generate personal health data of the patient. A storage device configured to perform tasks of a personal health record server (“PHRS”) comprising procedures to encrypt and store personal record data, to authenticate the access right of the requester, to create response to requester with associated personal health related information, to transfer personal health related information from/to information generating or storage devices; and to communicate with user via network. Personal health record server can be installed in a portable USB device and can start serving immediately after being inserted into a computer's USB port, personal health record stored can be accessed either by the said computer locally or by other computers requesting via internet through authenticated requests.

Abstract: A pillow height control system includes a pillow height control device adapted to receive a body position signal that is generated by the body sleeping position sensor. The pillow control device is placed between the bed and the cushioning material that supports the sleeper's head. The device controls an electromechanical device that moves a platform that supports the cushioning material up or down to a position accurate enough to minimize the stress on the neck and shoulder. The fact that sleeper changes sleeping position from time to time several times during his sleep fails many designs. In preferred embodiments, user can adjust the optimum heights of the pillow for different sleeping positions.

Abstract: An engine ignition control system includes a device adapted to receive the ignition timing signal which is generated by the engine original ignition pulse generator. The device derives a pulse sequence synchronous with the rotation of the engine from the original ignition timing signal. The device then generates a precision ignition signal from the synchronous sequence pulse at the optimum ignition angle. The precision ignition signal is supplied back to the original ignition system of the engine for the generation of the ignition sparks. The synchronous pulse sequence represents the angular position of the rotation of the engine in higher accuracy then the original ignition timing signal. In preferred embodiments, the synchronous pulse sequence represents the angular position of the engine up to 1 degree making high accuracy ignition advance control for most old engines that can produce only the ignition timing signal from its original ignition pulse generator possible.
