Abstract: A RFID based technology employs central computer(s) (10), reader/receiver(s) (11), lighting system(s) (12), product tag(s) (20), personal tag(s) (30), and/or shopping list(s) (40). Each product tag (20) includes integrated circuit(s) (21) and product data information (22), and optionally includes LEDs (23). Each personal tag 30 includes integrated circuit(s) (31) and personal data information (32). Each shopping list 40 includes circuit(s) (41) and a product shopping list (42). A wireless/wireline system is adapted from the RFID technology to provide product and personal lighting solutions.

Abstract: This invention relates to a method (and corresponding system) for providing location-aware media information and more specifically a method for providing location-aware audio content by an audio-presenting device capable of presenting audio content. On the audio source (401) comprising processing means (301) one or more sensors (404), may be positioned in order to locate the position(s) of one or more audio-presenting devices attached, close, or distant to said audio source. The sensors are used by receiving signal(s) to determine the location of the available audio-presenting devices. The audio-presenting device's (402, 403) location relative to the user's working position—in front of the display device (406)—may be estimated by the audio source (401) and thereby provides information items to the audio-presenting devices (402, 403) by the method according to the present invention so as to provide desired sound signals.

Abstract: RGB filter set and color estimation performance for RGB LED color sensing is provided. A criteria function describing an error between desired color matching functions and a spectral response of an RGB filter set is constructed. RGB filter set response characteristics based on the criteria function are then determined. Finally, color estimation parameters for substantially optimal color estimation with the RGB filter set are determined based upon the determined RGB filter set response characteristics. Computer readable code for constructing a criteria function is provided. Computer readable code for determining RGB filter set response characteristics is also provided. Finally, computer readable code for determining color estimation parameters is provided.
