Abstract: A volume meter 1 for measuring the volume of cups in a printing device has a reservoir formed by an indentation 5 in a foil 3. In the reservoir there is a viscous substance 11 comprising grease mixed with a colorant. The volume meter 1 has an adhesive 17 for fastening to a screen. The foil is free over an area 18 of the adhesive 17. This area 18 is larger than the spot that the viscous substance 11 covers after the spreading in the cups with the help of a doctor blade. The size of this spot is a measure for the volume of the cups and can be read with the aid of a scale division present on the foil 3. The indentation 5 in the foil 3 has such a form that the foil 3 does not fold double if a doctor blade is passed along the indentation 5, and the foil 3 at the place of the indentation 5 is pushed against the screen with the doctor blade in order to push the viscous substance 11 out of the reservoir.

Abstract: An interactive automatic system and technique for measuring and training of mental ability. In the illustrative embodiment, the invention is implemented on a computer which automatically presents a variety of visual and auditory stimuli. The system then measures reaction to the stimuli, adjusts certain stimulus parameters, and provides scores in response thereto. The scores are tabulated and displayed for analysis. In particular embodiments, the invention tests for physical reaction time, perceptual awareness thresholds, attention level, speed, efficiency and capacity of information processing by the brain and elementary cognitive processes, including memory, memory access and decision-making speed. The invention measures, identifies and quantifies noise in the subject's brain and elementary cognitive processing system, and the information exchange rate between the subject's left and right brain hemispheres.

Abstract: Methods are described whereby multiple users can swap a controller of consumer devices between themselves frequently, while each retains the ability to reinstate their own customized controller interface through a quick and simple yet secure log-on procedure. Stored data accessible to the controller is used to automatically upon log-on return a user to a system state associated with that user, which is typically the system state of the controller that existed the last time the user logged on thereto. The log-on procedure may include fingerprint and/or voice recognition. Additionally, time-out algorithms wherein the controller automatically shuts down and/or logs-off the current user as a security measure to prevent unauthorized users from gaining access thereto, may take into account factors other than merely the amount of time that has passed during which there has been no activity.

Abstract: A remote control uses IR (infrared) commands to control various consumer appliances made by various manufactures. The remote control is low-cost, consumer-friendly, programmable, has its own graphical display so it does not interfere with a TV or other viewing screen, and is capable of interacting with the internet or other data source to provide a rich set of functionality.

Abstract: Systems and methods are disclosed for using two or more cooperating but physically independent displays for enhanced viewing of data streams, where the viewing on one display does not interfere with the viewing on the other displays. The type of data streams may be complex streams such as multiple television (TV) broadcast signals or other video signals, internet data, or other local data such as information related to the state of a consumer's home appliances. The signals may include data embedded in the vertical blanking interval (VBI) for analog signals, or in dedicated slots in a digital signal according to protocols such as MPEG. The system includes a hand-held and portable remote control with a motion picture display, and hardware and/or software enabling interaction between a primary display (such as a TV) and the hand-held display.
