Project
Set Top Box
Application
In-Home Patient Monitor
Customer Need
More people are addressing health care at home. However, these same people are not trained care givers and require automated monitoring, reminders for medications and other tasks, and alert systems to notify for assistance. Collected data can be downloaded to doctors for analysis, adjustments to medication and other diagnosis. Some monitoring equipment is worn by the patient with wireless reporting ability. The use of a set top box allows on TV screen instructions, and interfaces via broadband modem and the Internet to the professional care giver.
AVID's Solution
A high end Power PC-based design was implemented, capable of running a high level Linux operation system. This allowed the use of library functions for communication, encryption, graphics, sound, and others. ISM-band RF interfaces were designed to collect data from remote, patient-worn monitor devices and panic keypad remotes. Ethernet was included as the link to the remote care giver locations; as well an option was included to add CDMA. Audio alarms alerted the patient if action was required. A modulation circuit allowed for custom screens to be displayed on specific TV channels. Multiple DSPs were implemented off a PCI bus from the PPC to allow for real time video processing.
