Abstract: A data acquisition system can include an acquisition device and a receiving device. The acquisition device includes inputs that receive data from sensors connected to a subject, a wireless and/or a wired transmitter that transmits data received by the inputs, and a housing carrying at least some of the components of the acquisition device. The housing may be wearable by a patient. The acquisition device may be switchable between a tethered data transmission mode and an untethered data transmission mode. The receiving device includes a receiver that receives data transmitted by the acquisition device, and may include an output that outputs data to a host. The system may be configured to transmit data from the data acquisition device to the local monitor point-to-point. The system is particularly useful for monitoring high acuity patients that may or may not require ambulation.

Abstract: A cable management and data acquisition method and apparatus to store system data and data from activity sensors when the sensors are disconnected from a monitoring system. The apparatus includes a housing, a first connection port operable to receive information from one or more activity sensors, a device interface coupled to the first connection port, a non-volatile memory coupled to the device interface; and an output port coupled to the device interface. The cable management and data acquisition apparatus may also include a digital-to-analog converter to convert analog signals from sensors to digital signals. Preferably, the device interface is an application specific integrated circuit (“ASIC”) that communicates with a signal processor in the monitoring processor. The signal processor responds to commands or messages from the monitoring processor and reads data from and writes data to the memory in the cable management and data acquisition apparatus through the ASIC.

Abstract: A signal acquisition method comprises the steps of recording ECG data signals on a tape in a first direction through a first high pass filter; and acquiring the data from the tape in an analyzer in a reverse direction through a second high pass filter having the same effective characteristics as the first filter.
