Abstract: Provided is a system and method for displaying the effects of light illumination on a surface. One or more light sources are illuminating a surface. The surface is divided into one or more cells. The orientation of each cell is determined and saved in an orientation field. A multidimensional light map value is derived and associated with the surface. The multidimensional light map value defines the combined illumination of the one or more light sources on the surface, and may optionally be a vector. At least one cell to be drawn is determined. For each cell to be drawn, an illumination value associated with that cell to be drawn is determined. The illumination value is based on the orientation field and the multidimensional light map value. The illumination value may be the dot product of the orientation field and the multidimensional light map value.

Abstract: A base station for controlling transmission power during the establishment of a communication channel utilizes the reception of a short code during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional access code. The ramp-up starts from a power level that is lower than the required power level for detection by the base station. The power of the short code is quickly increased until the signal is detected by the base station. Once the base station detects the short code, it transmits an indication that the short code has been detected.

Abstract: A medical device such as a defibrillator that incorporates corrective voice prompts that navigate users around operator errors. The voice prompts may, for example, address errors of readiness (e.g., failing to connect the defibrillator to an AC power source, failing to pre-connect electrodes, etc.), errors of omission (i.e., forgetting to do something, such as attempting to deliver a shock before the defibrillator is charged), and errors of commission (i.e., doing the wrong thing, such as attempting to shock VF when in the synchronization mode). The voice prompts may address errors in the delivery of therapy (e.g., attempting to shock VF when in the synchronization mode) or they may address errors other than in the delivery of therapy (e.g., failing to connect to an AC power source).
