摘要： A wireless EEG system for effective auditory evoked response, comprising an electrode array which is adapted to be attached to a person and senses voltages produced by the brain electrical activity of the person; transmitter electrically connected to the electrode array such that the transmitter produces a radio frequency signal corresponding to the voltages sensed by the electrode array, encodes the radio frequency signal with error correcting encoding and transmits the radio frequency signal by radio frequency telemetry through a transmitting antenna; the transmitter utilizing carrier frequency shift keyed circuitry to modulate a phase locked loop synthesized carrier frequency and reference frequency shift keyed circuitry to modulate a reference frequency to allow for non-return to zero format of the radio frequency signal obviating the need for Manchester encoding; receiver that receives through a receiving antenna the radio frequency signal produced and transmitted by the transmitter and whereby the receiver decodes the radio frequency signal and produces a data output corresponding to the radio frequency signal received by the receiver; and an operator interface connected to the receiver such that the operator interface receives as input the data output produced by the receiver such that the operator interface records a verbal stimulus given by an individual and provides an auditory stimulus whereby the operator interface displays the data output, such display providing a comparison of the brain electrical activity in response to said stimulus.

摘要： An interface pressure measurement device, comprising a sensor comprising two sensor sheets formed from thin flexible plastic material, each sensor sheet has a sensor area having flexible conductive ink printed thereon comprising a conductive surface with an electrical lead such that when the sensor sheets touch, an electrical contact is present forming a sensor switch, and the sensor also has sensor tubing. A digital device is connected to the sensor by the sensor tubing. The digital device comprises an enclosure, a push button, pressure transducer, signal conditioning, microcontroller with processor, analog-to-digital converter, memory, clock, display, buzzer and battery/power supply wherein the processor interrupts the battery/power supply current flow to shut off the digital device after a preset time. An inflator bulb having inflator tubing is connected to the digital device by the inflator tubing such that the inflator bulb is used to manually pump air through the digital device to the sensor whereby the pressure from the air in the sensor between the sensor sheets is sensed by the pressure transducer. When the microcontroller senses the opening of the sensor switch, the microcontroller through the processor transmits a signal to the display to provide a visual indication corresponding to the pressure in the sensor and transmits a signal to the buzzer to provide an audible tone.

摘要： An apparatus for low power radio communication comprising a transmitter having a frequency synthesizer and transmit antenna such that the frequency synthesizer comprises a phase locked loop circuit with a voltage controlled oscillator having a variable frequency output and with a loop filter/sample and hold circuit that allows opening of the synthesizer control loop and with special means of limiting the resulting frequency drift in the open loop state. The transmitter produces an output signal and the loop filter/sample and hold circuit holds the voltage controlled oscillator substantially on frequency such that the output signal remains stable, with a minimum of frequency drift, over a period of time when the phase lock loop synthesizer is set to an open loop state to allow frequency modulation unimpeded by the normal frequency correcting action of the synthesizer and for the frequency synthesizer to be partially powered down to reduce power consumption. The frequency modulation is linearized over a band of interest and undesired frequency shift at the initiation of modulation is suppressed. Receiver having automatic frequency control is included to extend the open loop transmit time of the transmitter, where the automatic frequency control system automatically tunes the receiver to correct for frequency error and for the frequency drift resulting from opening the phase locked loop of the frequency synthesizer, allowing communications to continue in the presence of such drift and of other frequency error.

The system comprises sensor which responds according to pressure exerted on the skin; a programmable microcontroller connected to the sensor; means for programming the microcontroller; and indicating means. A programming device operates software to changeably program the microcontroller with certain values of pressure and time, such that the level and duration of pressure on the skin and the duration of the absence of pressure thereon, are compared to the programmed values, is given to the wheelchair user, and the levels and duration of pressure are stored in memory. The programming device also can download from the memory the recorded values for review and analysis by a physician, clinician, therapist or other health professional. The indicators can be an audible alarm, like a beeper or buzzer, or a vibrator.A method for training a person to reduce the incidence of pressure sores occurring due to pressure exerted on the skin for a certain duration is also disclosed. The method comprises the steps of determining a specific maximum pressure position duration and a minimum pressure relief position duration for that person; measuring the duration of the person in a pressure position; alerting the person when the duration of the pressure position equals the maximum pressure position duration; alarming the person when the duration of the pressure position exceeds the maximum pressure position duration; continuing the alarming until the person is in a pressure relief position; measuring the duration of the pressure position; and prompting the person to continue the pressure relief position until the duration thereof equals the minimum pressure relief duration.
