Abstract: A portable computer in a store can be carried past a kiosk and wirelessly receive from the kiosk demonstration versions of software, along with an ID of the store. Later, after using the demonstration version, the user can access a Web server and purchase a full version of the software. During the transaction, the store ID is provided to the server, which can then credit the particular store at which the demonstration version was obtained with a sale.

Abstract: A system and method for converting a film camera into a digital camera uses an electronic device placed in a space of the camera that normally contains film. The device includes an image sensing array arranged in optical communication with a lens of the camera when a shutter is open. An audio sensor is used to detect sounds within the camera, and an acoustic pattern recognizer with a built-in training mode is used to determine if the detected sounds correspond with the shutter operation. The image sensing array is switched into an image capture mode when the acoustic pattern recognizer determines that the shutter is being opened. When the shutter is opened, a read-out circuit captures multiple image frames from the image sensing array. An image processor associated with the image sensing array processes the captured images using advanced image processing algorithms.

Abstract: A multimedia decoder unit having error concealment and fast muting capabilities. The audio decoder provides error concealment using a dynamic recovery delay that is based on the error rate of an input digital bitstream and also uses frame repeating. The decoder allows fast audio muting whereby audio can be muted within two audio frames of a mute signal that immediately freezes the video frame, e.g., a channel change. With respect to the dynamic recovery delay, a template of fixed length is used to inspect the last frames within the template. If error is found, then the error sum is used as an index into a table length which provides a dynamic template length. Error within the dynamic template length is computed and if larger than a tolerance, the current frame is muted. This allows the recovery delay to be adaptive and based on the error rate while still allowing mute merging.

Abstract: A flashlight for use in emergency situations includes a front light, a rear light, a translucent body with lights underneath to serve as a light beacon, and pivotable legs for supporting the flashlight in a freestanding position. When the legs are pivoted away from the flashlight body, a normally open switch closes, automatically turning on the lights in the translucent body and operating the flashlight as an emergency light beacon. The material used in the translucent body and/or the lights in the body are preferably colored red to designate an emergency situation. Front and rear light sources on the flashlight, which can be adjustable, provide ambient and task lighting in the same manner as conventional flashlights. The flashlight may include a cigarette lighter adapter and rechargeable batteries as an alternative power source to conventional batteries.

Abstract: A cart for maintaining items, which are used in a cleanroom, at a predetermined cleanliness level. The cart includes a cabinet having an internal cavity and opposed first and second internal walls. The cart further includes a shelf affixed horizontally within the cavity to form top and lower compartments within the cabinet. In addition, a lower horizontal track is affixed to the cabinet above the top compartment. A lower door is slidably affixed within the lower track. Additionally, the cart includes an upper horizontal track affixed to the cabinet above the lower track and an upper door slidably affixed within the upper track, wherein the upper and lower doors are movable in a horizontal direction above the top compartment. The top compartment is substantially isolated from contamination when the upper door contacts the first wall and the lower door contacts the second wall or when the upper door contacts the second wall and the lower door contacts the first wall.
