Abstract: Systems and methods for protecting an analog-to-digital converter (ADC) are provided. The provided systems and methods utilize comparators in a circuit of a stage of the ADC to compare a reference signal to an input signal and output one or more maximum signals when the input signal exceeds the reference signal. A decoder in the stage of the ADC may output a reset signal to another circuit in the stage of the ADC when a predetermined number of the maximum signals are received. When the other circuit receives the reset signal, the ADC may enter a protection mode to protect the ADC by ensuring that the excessive input signal is not propagated to subsequent stages.

Abstract: The present invention relates to a method for illuminating a first and at least a second light source in a light-emitting apparatus. This method comprises the acts of illuminating the first light source for a first period during which the first light source emits a plurality of light pulses, illuminating the second light source for a second period during which the second light source emits at least one light pulse, and repeating the illuminating acts. Furthermore, the present invention relates to a light-emitting apparatus for emitting light pulses and detecting these light pulses after they have been reflected or transmitted by a substance.

Abstract: A method allows the transmitter to change transmission to a better channel in order to minimize transfer interference. In general, the transmitter will monitor all RF channels and tag the data frames with a preferred channel ID. Upon reception of a tag within a given data frame indicating a change in preferred transmission channel, the receiver will commence listening on the new channel. To avoid transmission lapses, the transmitter may continue to transmit on the old channel for a predetermined amount of time or number of data frames to allow the receiver enough time to switch channels without losing any frames.

Abstract: An apparatus for sensing at least one physiological parameter of a patient and transmitting data related to the sensed physiological parameter to an external device. The apparatus comprises a detecting portion comprising at least one sensor interconnected with a connector, an acquisition portion comprising a connector interface configured to receive the connector, electronics for controlling the at least one sensor via the connector interface, receiving data related to the at least one physiological parameter from the at least one sensor via the connector interface and processing the received data, and a wireless interface for transmitting the processed data to the external device, and a power source for supplying energy to the acquisition module.

Abstract: A programmable neurostimulator is described herein. The neurostimulator comprises an internal part located in a patient's body and including an implant, at least one electrode, and a communication link; and an external part, connected to the implant by the communication link, the external part including a user interface. Wherein the user interface enables programming stimulation algorithms in the implant through the communication link so that, when activated, the implant generates electrical stimulation pulses by means of the at least one electrode located at sites of stimulation of the body.
