Abstract: Node meta-model systems and processes are disclosed which provide a seamless run-time integration between disparate devices, objects, frameworks, and/or agents (“objects”) without a priori knowledge of the types of objects, their capabilities, accepted commands/events, and underlying frameworks, and without expending any development effort. By introducing a node meta model, each system, device, and framework is described using its capabilities, properties, events, and methods of communications and thus an agent, at run-time, can figure out how to integrate/communicate with these systems accurately and without any development effort.

Abstract: A universal remote control transmitter for use with garage door openers including a number of switches whereby a user can program a transmitted modulation format and carrier frequency, and a controller for scanning the switches to determine the user programmed selections. The controller, in response to the programmed selections, outputs the required modulation to a selected transmitter, as well as direction to fine tune the transmitter to the particular carrier frequency. Also included is a power sensor circuit that responds to a change in power supply voltage by adjusting the modulation to maintain a constant peak transmitter output power.
