Abstract: In one embodiment, a system and associated processes for transparent client-side cryptography are provided. In this system, some or all of a user's private data can be encrypted at a client device operated by the user. The client can transmit the encrypted user data to a content site that hosts a network application, such as a social networking application, financial application, or the like. The content site can store the private data in its encrypted form instead of the actual private data. When the content site receives a request for the private data from the user or optionally from other users (such as social networking friends), the server can send the encrypted user data to a client associated with the requesting user. This client, if operated by an authorized user, can decrypt the private data and present it to the authorized user.

Abstract: A workpiece system with a reciprocating motion which includes a motor assembly for producing an output drive signal with a periodic force pulse. The drive signal is coupled to a driven member assembly through a magnetic arrangement, wherein the driven member assembly has a workpiece mounted thereon with a return spring assembly. The driven member assembly has a resonant mechanical frequency. As the RPM of the motor increases from zero following startup, the drive signal frequency increases to the point very near resonance, where the energy from the drive signal is transferred into the reciprocating motion of the driven assembly, producing an effective amplitude of workpiece motion.

Abstract: In an aspect, the invention is directed to a set that includes a miniature vehicle that drives one or more wheels with an on-board motor that draws power from an on-board power source. A switch is provided to control the transmission of power from the power source to the motor. A first drive-related magnetically-responsive member is movable between first and second positions to control whether the switch is off or on. A second drive-related magnetically-responsive member is positionable to interact with the first drive-related magnetically responsive member to move the first drive-related magnetically-responsive member to the second position so as to close the switch.

Abstract: The system periodically measures the battery voltage of the toothbrush and the current in a stator portion of the motor for the appliance. The amplitude of movement of the toothbrush workpiece is determined from the measured stator current. A circuit/control program changes the duty cycle or pulse width of the drive signal from the motor if the battery voltage drops below a first threshold value and a circuit or control program changes the drive frequency of the appliance if the amplitude of the workpiece movement falls below a first threshold value. A circuit/control program terminates the operation of the toothbrush if the voltage drops below a second threshold value or if the amplitude drops below a second threshold value, both of which are less than the respective first thresholds.

Abstract: An adaptive system for a personal care appliance, such as a power toothbrush, having a workpiece which is driven through an amplitude of motion by a drive mechanism which includes a stator member includes a circuit (13) for measuring average electrical current through the stator member and stored information (19) in the personal care appliance which relates the average current values through the stator during operation of the device to corresponding amplitude of motion of the workpiece. A processor (17) utilizing a stored program adjusts the operating frequency to produce a stator current value which correlates to the desired amplitude of motion of the workpiece.

Exemplary apparatus for dispensing animal food include a food hopper for containing animal food operatively connected to a food handler that launches a portion or ration of the animal food away from the unit in response to detecting a triggering action of the animal.

Abstract: A method for tuning resonant spring assembly systems used in appliances such as power toothbrushes, particularly leaf spring systems, includes the step of measuring the frequency-dependent amplitude of the appliance workpiece, and then removing a portion of the spring member so as to decrease its spring rate sufficiently that the resonant frequency of the spring member closely approximates the drive frequency of the appliance.

Abstract: The adapting system for a resonant drive appliance includes a circuit for measuring the back EMF induced in the stator coil of the motor following turn-off of the appliance. The frequency of the back EMF signal is determined from the zero crossings of the EMF signal.

Abstract: The present invention is a method and system for autonomous learning of Braille by an unsighted user. The system allows the unsighted user to pass a card over an RFID reader so as to trigger an audible response that is indicative of an indicia (Braille word or character) embossed on the card. The embossed card further comprises an RFID tag and a series of raised indicia surfaces representative of a Braille-based word or character. The tag transmits a signal indicative of the word or character to the receiving (via receiver) micro-controller which will convert the signal to an audible tone to be transmitted through an output device. The system has a memory which holds a library of tones corresponding to a signal to be converted. An autonomous record mode allows the system user to record an audio input to be stored in the library, or utilize an interface port, or removable memory, for downloading an input.

Abstract: The brushhead includes a brushhead member which includes a bristle field, the brushhead member being adapted for cleaning teeth as part of a power toothbrush, wherein the brushhead in operation moves in a reciprocating action. In one embodiment the brushhead includes a rim member which extends around at least a substantial portion of the brushhead, the rim member extending around the entire bristle field and having an upper edge which is lower than the top of the bristles. The rim member has a different flexibility than the bristles so that the movement of the rim member and the bristles is out of phase during operation of the toothbrush, which results in fluid from the bristles being directed toward the teeth during operation of the toothbrush.
