Data signal. Data signal is a method of how information is transferred; usually it is transferred in binary code in signals or pulses and may be contained in a packet.

Wireless communication networks for providing remote monitoring of devices

Wireless communication networks for monitoring and controlling a plurality of remote devices are provided. Briefly, one embodiment of a wireless communication network may comprise a plurality of wireless transceivers having unique identifiers. Each of the plurality of wireless transceivers may be configured to receive a sensor data signal from one of the plurality of remote devices and transmit an original data message using a predefined wireless communication protocol. The original data message may comprise the corresponding unique identifier and sensor data signal. Each of the plurality of wireless transceivers may be configured to receive the original data message transmitted by one of the other wireless transceivers and transmit a repeated data message using the predefined communication protocol. The repeated data message may include the sensor data signal and the corresponding unique identifier. Furthermore, at least one of the plurality of wireless transceivers may be further configured to provide the original data messages and the repeated data messages to a site controller connected to a wide area network. The site controller may be configured to manage communications between the wireless communication network and a host computer connected to the wide area network.

System for long-term remote medical monitoring

A system for long-term remote medical monitoring is especially suitable for the medical supervision of astronauts onboard a space station. The system includes at least one autonomous sensor unit (SU) with a sensor (1) and transmit/receive electrodes (2) connected to a microchip (3) and mounted on a carrier (4) in the form of an adhesive bandage that can easily be applied to the skin of the subject astronaut (11). The system further includes a body transceiver (10) that is worn on the body of the subject and acts as a centralized transmitting and receiving unit, and a portable data logger (12). Medical data such as the pulse rate and the like, as well as environmental data such as the ambient surrounding air temperature, are sensed by respective allocated sensor units (SU) and transmitted from the sensor units as electrical signals via the skin and other body tissues of the subject (11) to the body transceiver (10). From the body transceiver (10), the data signals are further transmitted, for example by a radio or infrared transmission, to the data logger (12), where the data can be recorded, displayed, processed, or further transmitted via a satellite (14) to a base station (13) or a ground-based facility such as a hospital (15). Polling signals are also transmitted from the body transceiver (10) to the sensor units (SU) in a wireless manner through the skin and other body tissues of the subject.

System and method for distributed input distributed output wireless communications

A system and method are described for compensating for frequency and phase offsets in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”). For example, a method according to one embodiment of the invention comprises: transmitting a training signal from each antenna of a base station to one or each of a plurality of wireless client devices, one or each of the client devices analyzing each training signal to generate frequency offset compensation data, and receiving the frequency offset compensation data at the base station; computing MU-MAS precoder weights based on the frequency offset compensation data to pre-cancel the frequency offset at the transmitter; precoding training signal using the MU-MAS precoder weights to generate precoded training signals for each antenna of the base station; transmitting the precoded training signal from each antenna of a base station to each of a plurality of wireless client devices, each of the client devices analyzing each training signal to generate channel characterization data, and receiving the channel characterization data at the base station; computing a plurality of MU-MAS precoder weights based on the channel characterization data, the MU-MAS precoder weights calculated to pre-cancel frequency and phase offset and / or inter-user interference; precoding data using the MU-MAS precoder weights to generate precoded data signals for each antenna of the base station; and transmitting the precoded data signals through each antenna of the base station to each respective client device.

System and method for acquiring data

A system for acquiring, and displaying, data such as physiological data, from a plurality of data connection devices, each of which monitor one or more different parameters and output data at different sampling frequencies based on their own system clocks. The system receives the data signals at different sampling frequencies and associates each sample of each signal with a time stamp derived from a single master clock. Low rate and high rate data are treated differently. Low rate data is associated with the current value of the master clock, where as high rate data is time stamped by giving the first sample a time stamp equal to the current value of the current master clock, subsequent samples being given an estimated time stamp based on the expected interval between samples derived from the sampling frequency of the data collection device, and the timescale given to the first example. The estimated time stamp may be periodically corrected, and the estimation calculation can be improved by correcting the value used for the interval between samples. The different signals can be displayed together on a display aligned with respect to a time axis. The system can display, the data in two different timescales, one showing a few seconds of data and one showing a few hours of data. The data traces are scrolled across the time axis, new data being added to one end of the trace.
