摘要： A method and a device for diagnosing brain injury (e.g. concussion) based on analysis of electromyogram (EMG) signals and presence of neurological modulation impairment of motor activity are described. The method consists of recording specific EMG signals under defined conditions, processing the acquired EMG signals, extracting the relevant information, and making diagnosis of brain injury and disorders that are associated with brain pathology. Specifically, the steps and device involved in the method include placing an EMG electrode set on the subject's body area, acquiring EMG signals from a subject's muscle(s) undergoing contraction, processing the acquired EMG signals using a signal processing algorithm that includes Fourier transformation. The resulting EMG data with a frequency domain (frequency power spectra) are then analyzed in comparison with databases stored in the device and used to determine anomaly of diagnostic value in the EMG power spectra from subjects. A diagnosis can be made based the altered EMG frequency power spectra that reflect the neurological modulation impairment of motor neurons. The diagnostic value, determination, management suggestions are displayed on the device.

摘要： A method and apparatus for transferring protected digital AV content. The apparatus 10 includes a specially adapted microprocessor 12 with firmware allowing the microprocessor to control and transmit for storage and for display device 14 digital AV content data in the form of digital signals. A source storage device is connected to the microprocessor 12 by means of link 26. At least one sink storage device 20 is also connected to microprocessor 12 by link 28. The firmware allows the microprocessor to time the amount of material transferred to sink 20 to that allowed by the appropriate copy protection specification. The method limits the amount of data transferred to the programmed amount for example one second slices ending on a frame end. After each increment of data is transferred the amount remaining on source 16 is deleted. The process continues until all of the desired material is transferred from source 16 to sink 20.

摘要： Memory die are provided with programmable chip enable circuitry to allow particular memory die to be disabled after packaging and/or programmable chip address circuitry to allow particular memory die to be readdressed after being packaged. In a multi-chip memory package, a memory die that fails package-level testing can be disabled and isolated from the memory package by a programmable circuit that overrides the master chip enable signal received from the controller or host device. To provide a continuous address range, one or more of the non-defective memory die can be re-addressed using another programmable circuit that replaces the unique chip address provided by the pad bonding. Memory chips can also be also be readdressed after packaging independently of detecting a failed memory die.
