A device for detecting the position of a human finger or other object on a touch-sensitive scrolling pad. Dual independent oscillators may be used to generate two pulse trains at frequencies dependent upon the capacitance of two conductors resulting from the position of the finger on the conductors. The pulses from each oscillator may be counted over a time interval. A ratio-metric measurement may be taken by calculating the ratio of the two counts, and a sum may also be calculated. The ratio of the two counts relates to finger position on the device, and their sum relates to finger pressure upon the device.

A haptic device provides indirect haptic feedback and virtual texture sensations to a user by modulation of friction of a touch surface of the device in response to one or more sensed parameters and / or time. The sensed parameters can include, but are not limited to, sensed position of the user's finger, derivatives of sensed finger position such as velocity and / or acceleration, sensed finger pressure, and / or sensed direction of motion of the finger. The touch surface is adapted to be touched by a user's bare finger, thumb or other appendage and / or by an instrument such as a stylus held by the user.

A method and system for correlating control surface finger pressures to identifying biometric characteristics of a user from a computer input device, such as a mouse. Pressure sensors attached to a computer mouse sense the biometric characteristics, which are correlated to identifying biometric characteristics using a correlation model. The correlation model is derived from a registration process in which a baseline biometric attribute-to-identity correlation is rendered based on statistical analysis of registration signals generated by users. During routine use, the correlation model is use to continuously authenticate the identity of the user from surface finger pressures on the computer mouse.

A broadcast control apparatus for visual data includes a touch screen (32, 34) display panel operable to receive and display visual data simultaneously in real time from a plurality of visual sources. It also includes a touch screen graphical panel for the retrieval of control functions from a control function register. The visual data from at least one of the visual sources is selectable for use by finger pressure on the associated portion of the touch screen (32, 34) display panel and the selected data is modifiable in accordance with the retrieved control function.

A cosmetic case containing a replaceable inner case which can be easily removed or inserted, and which is specifically structured to maintain the cosmetic material contained therein in a fresh and useable condition. The invention is comprised of an outer case with a floor area and inner peripheral wall defining a space for an inner container, an outer cover attached by a hinge to the outer case, a main latch employed to hold the outer cover closed, a replaceable inner container providing a cosmetic holding space, an inner container cover capable of opening or closing over the cosmetic holding space, and a sub-latch employed to hold the inner cover closed against the inner container. The inner case is equipped with a hinge part to allow opening and closing of the inner cover, the hinge part fitting into a cutout section on the peripheral wall of the outer case so as to expose the hinge and thus allow wide angle opening of the inner case cover. Inner case installation is aided by small protruding ribs formed within the outer case with the purpose of indexing and securing the inner case. An orifice is provided in the floor of the main case to allow the inner case to be pushed up and removed by finger pressure applied from below. The cosmetic case is characterized by a push-type latch mechanism which opens the outer and inner case covers simultaneously in one movement, an effective sealing mechanism between the inner case and cover, and specific inner cover structures to inhibit the fall of condensation droplets onto the cosmetic surface.

An electronic keyboard simulates the keyboard action of one or more acoustic pianos and / or organs. Sensors associated with each key capture the force exerted on the key, the speed of the key and the position of the key to compute an amount of force to apply in feedback to the depressed key. An actuator associated with each key provides the computed feedback value as a counter-force to the player's finger pressure. Feedback may be computed in one or more processors by applying the sensor readings to a system model of the desired instruments mechanical key action. Also, feedback may be determined through a lookup table containing feedback values defining a particular instrument's action. The player can switch between different instrument action definitions as desired, and may tune certain parameters to achieve a customized action.

A color image sensor sequentially acquires a plurality of fingerprint images when a finger is pressed against the detector surface. A color information extraction unit detects the finger color in synchronization with the input of the plurality of fingerprint images. An areal information extraction unit detects a physical quantity representing the pressure applied by the finger to the color image sensor when the plurality of fingerprint images are acquired, particularly, the quantity related with the area of the finger in contact with the detector surface. A living body identification unit determines whether the finger is a live or dead one by the analysis of correlation between the physical quantity and the finger color. According to this configuration, even if the finger color does not change much, it is possible to distinguish living bodies from dead ones if there is a sufficient correlation with information such as the area of the fingerprint that reflects the finger pressure. The thickness of the fingerprint input unit is approximately 1–2 mm, determined by the sum of the thickness of the planar light source and that of the color image sensor.

A guide wire for use in a medical procedure having a shapeable tip integral with and made from the distal end of a superelastic nitinol distal section of the guide wire, wherein the shapeable tip can be finger kinked. Such a guide wire includes an elongated core made from a superelastic nitinol alloy at the distal end, the distal end of the elongated core having a tapered section leading to a shapeable distal tip. The shapeable tip is an extension of the distal end of the nitinol distal section, and includes permanent strain hardening from at least two different radial directions imparting crystallographic texture in the radial directions that eliminate superelasticity so that permanent deformation can be achieved with finger pressure.
