    摘要： A system for detecting post-operative retained foreign bodies has a data storage unit adapted to receive and store a reference image of a surgical object, and a data processor in communication with the data storage unit. The data processor is configured to receive an image of an internal region of a patient and to receive the reference image from the data storage unit, and the data processor is configured to perform operations based on an algorithm to compare the reference image to at least a portion of the image of the internal region of the patient and determine whether a retained foreign body is present in the patient.

    摘要： An artificial Central Pattern Generator (CPG) based on the naturally-occuring central pattern generator locomotor controller for walking, running, swimming, and flying animals may be constructed to be self-adaptive, by providing for the artificial CPG, which may be a chip, to tune its behavior based on sensory feedback. It is believed that this is the first instance of an adaptive CPG chip. Such a sensory feedback-using system with an artificial CPG may be used in mechanical applications such as a running robotic leg, in walking, flying and swimming machines, and in miniature and larger robots, and also in biological systems, such as a surrogate neural system for patients with spinal damage.

    摘要： An imaging array is integrated with region of interest selection, template storage and processing circuitry for transforming raw image data for respective pixels in terms of defined color opponencies and analyzing (e.g. by histogramming or the like) the transformed image data over respective regions of interest of arbitrary size to extract color signatures of portions of a scene. The color signatures may then be compared to templates for object recognition, tracking or other purposes.

    摘要： An integrated circuit for controlling a DC motor is disclosed. The integrated circuit includes at least one digital position and speed circuit (DPS) for providing measurements of speed, position, and direction of the motor, the DPS being in signal communication with the motor for receiving a pair of signals having a quadrature relationship; and at least one programmable gain amplifier (PGA) electrically coupled to the motor, the PGA being configured to receive a feedback signal indicative of current flowing through the motor and to apply a second signal to the motor for adjusting the speed of the motor; and at least two analog-to-digital converters (A/D), one A/D being used to quantize the output of the PGA for an off-chip processor; and another A/D to provide motor reference position from an analog sensor, such as a potentiometer; and at least two digital-to-analog converters (D/A), one D/A used to set the motor voltage; and another D/A used to set the motor current limit. The integrated circuit can be incorporated into a larger motor control loop which further includes a summing amplifier for providing the feedback signal to the motor that is indicative of current flowing through the motor; a buffer amplifier electrically for sensing the output current of the motor, and a processor for providing control signals to the system monolithic module and for receiving the measurements of speed, position, and direction of the motor.

    摘要： A system for simulating biofidelic signals includes a transducer and a neural transmitter port. The transducer is affected by a parameter and provides an alternating electrical signal based on an effect of the parameter. The neural transmitter port receives a processed electrical signal and outputs the processed electrical to a neural transmitter. The system further includes an input portion, a band-pass filter, and an integrate-and-fire mechanism. The input portion outputs a first signal based on the alternating electrical signal. The band-pass filter outputs a first filtered signal based on the first signal. The integrate-and-fire mechanism generates the processed electrical signal based on the first filtered signal.
