Abstract: An apparatus can include a first planar inductive sensor including two oscillator coils and two sensing coils. The apparatus can also include a second planar inductive sensor independent of the first sensor and also including a pair of oscillator and sensing coils. The apparatus can further include a high frequency alternating current carrier generator configured to inject high frequency alternating current carrier signals into the oscillator coils. The carrier signal for the oscillator coil of the first planar inductive sensor is 180 degrees out of phase with a 2nd oscillator coil of the same planar inductive sensor, and wound in an opposite geometric direction, and the oscillator coils of the other inductive sensor can also be wound similarly The two sensing coils of the first planar inductive sensor can be 90 degrees out of phase with each another, and the sensing coils of the other inductive sensor can also be wound similarly.

Abstract: A planar linear inductive position sensor is formed on a substrate and includes at least one oscillating coil, a first sensing coil having opposing edges extending beyond opposing edges of the oscillating coil along a linear axis along which a linear position of a conductive target is to be sensed, and a second sensing coil having opposing edges extending beyond opposing edges of the oscillating coil along the linear axis.

Abstract: A motor control system for controlling an electronically controlled motor based at least partially on a signal from a motor timer is described. The system includes a motor controller coupled to the electronically controlled motor and configured to drive the electronically controlled motor and a control device coupled to the motor controller. The control device is configured to provide the motor controller with a first speed control signal corresponding to a first speed in response to a start signal from the motor timer, monitor a first length of time the first speed control signal is provided to the motor controller, and provide the motor controller with a second speed control signal corresponding to a second speed after a first predefined length of time.

Abstract: A notification system and an automated product registration system are disclosed. The notification system may contact multiple persons simultaneously and use text-to-speech to speak a message to each person over the phone. The notification system may first determine whether a live person has answered the phone before speaking the message. The notification system may be used in conjunction with an automated voice-activated product registration system.

Abstract: An exemplary embodiment of a system, method and computer program product for interactive voice notification is disclosed. The method for notifying a user of an event can include the steps of: receiving user input on notification criteria; listening for an event; detecting the event; calling the user by telephone when the detected event matches the notification criteria; requesting a user response indicating a live person answered the telephone; receiving the user response indicating the live person answered the telephone; and providing the user with information about the event. In one embodiment, the method can further include: requesting a user authentication; determining if the user authentication is valid; and not providing the user with the information about the even if the authentication is not valid. In another exemplary embodiment, the method can further include: storing the detected event in a database; and querying the database for events matching the notification criteria.
