Abstract: A vehicle occupant detection system includes at least one weight sensing pad, at least one infrared sensor, and at least one motion sensor disposed within an automobile. Each of the at least one weight sensing pad, the at least one infrared sensor, and the at least one motion sensor is in operational communication with each of a battery and a computer system of the automobile. The computer system is configured to activate at least one of a horn, an alarm, an engine, at least one power window, a wireless communication with a remotely disposed fob, a wireless text communication with a remotely disposed personal electronic device, and a cellular communication with an emergency responder when at least one of the at least one infrared sensor, the at least one of the weight sensing pad, and the at least one motion sensor detects a passenger disposed within the vehicle.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for selecting, from a unified electrical power grid model, a first proper subset of elements of the model. A first electrical grid simulation model is selected. A second, differing proper subset of elements of the model are selected. A second electrical grid simulation model that differs from the first electrical grid simulation model is selected. A set of boundary conditions common to the first electrical grid simulation model and the second electrical grid simulation model are determined. Operation of the electrical power grid is simulated, and can include (i) simulating, using the first electrical grid simulation model, the first proper subset of elements of the unified model, and the set of boundary conditions; and (ii) simulating, using the second electrical grid simulation model and the second proper subset of elements of the unified model, and the set of boundary conditions.

Abstract: A method of registering an image onto a sheet of media on an imaging surface of a printer having a printhead for imaging onto the sheet, comprising: detecting a position of said sheet of media being advanced onto the imaging surface using a first sensor positioned along said media path upstream of the printhead; and firing the printhead at a time based on the detected position and a calibrated distance between the sensor and the printhead.
