A system providing an inductive power and data link between an external transmitter and miniature internal receiver is presented. The system is suited to applications where the receiver must be of a small size and the system must consume very little power, such as an implanted biomedical device. The system is also compatible with systems where bi-directional communications are required. The novel transmitter and receiver form an improved forward data telemetry system. The transmitter consists of a Class-E converter with its optimum operating frequency being synchronously, instantaneously and efficiently altered in accordance with the data to be transmitted, thereby producing an FSK modulated magnetic field of substantially constant amplitude. The constant amplitude output allows for the continuous, data-independent transfer of power to the miniature receiver and its associated electronics. The present invention also represents an improvement over the high efficiency Class-E converters previously patented by the inventors. The receiver consists of a coil and an integrated rectifying system to recover operating power from the incident magnetic field, as well as an FSK demodulator whose operation is based on the multiphase comparison of charging times of integrated capacitors. The described FSK demodulator approach removes deleterious effects resulting from low-frequency changes in the transmitter frequency, and eliminates time distortion artifacts generated by circuit imbalances and asymmetries in the power recovery process. The combination of the transmitter and receiver improvements yields a reliable data transfer system unaffected by circuit imbalances and incidental variations in the amplitude and frequency of the magnetic field.

A fully integrated wireless spread-spectrum sensor incorporating all elements of an “intelligent” sensor on a single circuit chip is capable of telemetering data to a receiver. Synchronous control of all elements of the chip provides low-cost, low-noise, and highly robust data transmission, in turn enabling the use of low-cost monolithic receivers.

In a system for video data capture and sharing client devices may include one or more video cameras and sensors to capture video data and a local buffer memory for storing the captured video data. The system uses inputs from various sources, including sensors, to determine an operating mode. Based on the operating mode, video recording settings are set for the video cameras to change the size of the video data that is generated and stored in the local buffer memory to optimize its use. When the operating mode corresponds to an event of interest, the data recorded is larger, with higher video quality parameters, and when the operational mode corresponds to video footage of no interest, the data recorded is smaller, with lower video quality parameters. Additionally, other actions can be taken based on the operational mode, such as over-write the video recording parameters, notify users of likely loss of recorded data, and the like.

An integrated external controller/charger system for an implantable medical device is disclosed comprising an external controller/charger device with a Graphical User Interface (GUI) and first battery, and an external charging coil assembly coupleable to the external controller/charger device and including or associated with a second battery. The second battery is used to energize a charging coil in the external charging coil assembly, while the first battery is used to power other aspects of the system (data telemetry circuitry, control circuitry, the GUI, etc.). Because the second battery powers the relatively high-power charging function, the first battery in the external controller/charger device can be made smaller. Additionally, the second battery enables a suitable external controller device (e.g. a mobile device such as a cell phone) to provide charging functionality even if its first battery is otherwise inadequate.

A seismic data acquisition unit includes a data acquisition and digital circuit which receives an analog seismic signal and digitizes the signal. The digitized seismic data uses data telemetry and a repeater device to receive the compressed data and transmit the compressed data to a seismic central control unit. The data decompressor takes the data from the data compressor and decompresses the data. The decompressed data is then compared with the original digitized data to determine the amount of noise resulting from the compression process. The compression noise is compared to the ambient noise, and if the compression noise exceeds a predefined criterion, then the compression ratio in the data compressor is adjusted for a lower degree of compression. The process is repeated until the amount of compression noise, relative to ambient noise, is satisfactory.
