The '904 patent is directed towards a system for patient monitoring that includes a plurality of non-integrated components including a display, a monitor, one or more modules, and at least one patient parameter measuring device. The display has a flat glass front with a blackened border that appears continuous but allows the passage of light during alarm situations. The display includes a housing with openings on the right and left sides which allow the passage of light during alarm situations. The display also includes a prominent programmable button which enables easy alarm silencing. The monitor can be fixedly attached to the back of the display in a "backpack mounting" configuration to free up bedside space. Optional monitor and display cabinets are capable of housing power supplies and cables and provide for additional free space. The monitor, module(s), and patient parameter measuring device(s) are all interconnected via Dual Serial Bus (DSB) interfaces.
