Abstract: A heartbeat or pulse generator device is provided separately for use in or in combination with a comfort product such as a plush toy. The heartbeat generator device includes an automatic control system that provides for controlled operation of the heartbeat generator while compensating for natural movements during use. The heartbeat generator device contains a pulse generator to create the motion necessary to cause the heart to “beat” twice early in a beat interval. The heartbeat generator device to increase battery longevity by allowing the generator device to selectively shut off when it senses that the animal or other user is no longer interacting with the product. As the animal interacts, the emulated heartbeat continues. When the animal stops interacting for a period of time, the heartbeat will stop, and battery life is preserved. The heart will restart when motion is detected once again.

Abstract: Stabilization, via active-feedback positional drift-correction, of an optical microscope imaging system in up to 3-dimensions is achieved using the optical measurement path of an image sensor. Nanometer-scale stability of the imaging system is accomplished by correcting for positional drift using fiduciary references sparsely distributed within or in proximity to the experimental sample.

Abstract: A telephone remote control system for direct control of the dialing sequence of a telephone from a personal computer. The remote control system includes an RF transmitter unit mounted on a personal computer and an RF receiver unit within a phone. The transmitter receives dialing commands from a personal computer and transmits those commands to a receiver unit via an RF signal. The receiver unit receives the dialing commands from the transmitter unit and directly controls the dialing sequence of the telephone.

Abstract: A solid state x-ray detector has a set of bilayers formed on its front surface. Each bilayer includes a spacing layer and an absorbing layer which have different indexes of refraction, and the impinging x-rays strike the bilayers at an angle which satisfies the Bragg condition. As a result, x-rays polarized in one direction are substantially reflected while x-rays polarized in an orthogonal direction pass through the bilayers for detection by the solid state x-ray detector.
