A medical probe includes an insertion tube, having a longitudinal axis and having a distal end. A distal tip is disposed at the distal end of the insertion tube and is configured to be brought into contact with a body tissue. A joint couples the distal tip to the distal end of the insertion tube. A joint sensor, contained within the probe, senses a position of the distal tip relative to the distal end of the insertion tube. The joint sensor includes first and second subassemblies, which are disposed within the probe on opposite, respective sides of the joint and each include one or more magnetic transducers.

A method of removing cards is also disclosed, enabling movement of cards in at least two directions due to the presence of a card guide offset.

Disclosed is a digitally controlled multi-phase voltage regulator system providing regulated power to electronic components that have variable power requirements. Power is supplied by one or more power integrated circuits (IC) each having a high side power switch controlled by pulse width modulated signals and a low side power switch. The power IC senses voltage at the load and has an on-chip current mirror for generating a current that is a ratio of current delivered to the load. The power IC also has current limiting and on-chip temperature sensing components. The voltage and current information is digitized and provided to a control integrated circuit (IC). The control IC receives this digitized information as well as user provided parameters and, in the regulation mode of operation, provides digitized pulse width modulated control signals to the power IC. In an active transient response mode of operation, the control IC provides signals to turn either the high side switches or low side switches ON. Fault detection circuitry identifies over voltage, under voltage, and excessive temperatures. All communications between the control IC and the power IC are digital providing high bandwidth, optimal control frequency response, noise immunity and efficient active transient response.

A reliable, safe, accurate, low noise, inexpensive, portable amplifier circuit is adapted to accurately amplify both AC and DC neural response signals. A patient or subject is electrically connected to a multi-channel system for electrically measuring the patient's AC and DC neural response signals at a plurality of locations using electrodes connected through a multi-electrode cable. The neural response signals are input to a digital DC amplifier to filter, amplify and digitize the neural response signals. Digitized neural response signals are converted to optical signals and transmitted via a fiber optic cable to an interface that is preferably connected to a patient stimulus generator (e.g., a Ganzfeld stimulator or pattern stimulator for multi-focal ERG). The system also includes a stand-alone computer such as an IBM® compatible Personal Computer (PC) for two-way communication with the interface via a standard data interface cable (e.g., a USB cable). In the preferred embodiment, a digital DC amplifier is worn by the patient and receives each neural response signal at a two-conductor balanced input; a surge suppression circuit limits excessive voltage transients at the input. The neural response signal is next input to a balanced buffer amplifier stage for impedance matching and the buffered neural response signal is then input to a balanced, adjustable pre-amplifier stage having an adjustable gain which can be varied (e.g., from ×1 to ×64). The buffered, amplified neural response signal is then digitized for storage in a memory and transmission to a fiber-optic digital transmission circuit. An adjustable impedance element generates a DC offset compensation signal used to control a D.C. offset compensation amplifier to generate an offset control signal for input to gain-adjustable pre-amplifier stage, to maximize sensitivity and usable dynamic range.

A method of identifying edge swipe gesture has steps of respectively reading sensing signals on an edge area under a hover mode and on a non-edge area under a touch mode; determining if a touch object has appeared on the edge area after determining that the object has appeared on the non-edge area, calculating a displacement of the object moving from the edge area to the non-edge area within a preset time and determining if the displacement exceeds a preset distance, and determining that the movement of the touch is identified as an edge swipe gesture if the displacement meets the condition. Accordingly, the present invention can perform valid touch on the edge area, rendering effective identification of edge swipe gesture and an increased success rate of the identification.

A touch sensor is installed inside a liquid crystal display panel to sense a touch operation and includes a light sensing part including a photodiode, a capacitance sensing part including a liquid crystal capacitor, and a sensing signal output part. The light sensing part generates a control signal corresponding to a variation in the amount of external light when the liquid crystal display panel is touched. The capacitance sensing part varies the control signal based on a variation in the capacitance of the liquid crystal capacitor when the liquid crystal display panel is touched. The sensing signal output part generates a sensing signal in response to the control signal and determines an output timing of the sensing signal.

A multi-level semiconductor memory device for storing multi-level data having three or more values is implemented by utilizing a nonvolatile memory device for storing 2-valued data. Identification of successive 16-bit data externally applied is performed with external address bit AA [2], and a storage block is selected with external address bit AA [23]. Upper word data LW and lower word data UW are compressed into byte data of 8 bits; respectively, and stored in a memory cell array.

A fuel injection characteristic sensing device obtains an injection characteristic of a target injector (an injector of each cylinder of a multi-cylinder engine) at each time. The device has a program for sequentially sensing fuel pressure at a sensing point corresponding to a fuel pressure sensor, which is provided at a fuel inlet of each injector, based on an output of the fuel pressure sensor. The device has a program for detecting predetermined timings (injection timings such as an injection start timing and an injection end timing) in a series of operations concerning fuel injection of the injector of each cylinder based on the sequentially sensed fuel pressure. Thus, the injection characteristic at each time including a temporal characteristic change can be obtained.

Near-field sensing of wave signals, for example for application in headsets and earsets, is accomplished by placing two or more spaced-apart microphones along a line generally between the headset and the user's mouth. The signals produced at the output of the microphones will disagree in amplitude and time delay for the desired signal—the wearer's voice—but will disagree in a different manner for the ambient noises. Utilization of this difference enables recognizing, and subsequently ignoring, the noise portion of the signals and passing a clean voice signal. A first approach involves a complex vector difference equation applied in the frequency domain that creates a noise-reduced result. A second approach creates an attenuation value that is proportional to the complex vector difference, and applies this attenuation value to the original signal in order to effect a reduction of the noise. The two approaches can be applied separately or combined.

A first ignition cylinder that performs ignition first is set based on an engine stop position in automatic start. Existence/nonexistence of a misfire in the first ignition cylinder is determined based on whether a difference ΔNe between engine rotation speed at a predetermined crank angle in an interval from timing immediately before the ignition to timing immediately after the ignition of the first ignition cylinder (e.g., at TDC of first ignition cylinder) and engine rotation speed at a predetermined crank angle before ignition of a second ignition cylinder (e.g., at TDC of second ignition cylinder) is equal to or smaller than a predetermined misfire determination threshold value Nef. When misfire time number of the first ignition cylinder exceeds a predetermined value, fuel supply to the first ignition cylinder is prohibited and the automatic start is started from the second ignition cylinder.
