A proximity sensor device and method is provided that facilitates orientation changes in displays. The proximity sensor device and method provide a user with the ability to indicate an orientation change in a display using the sensing region of a proximity sensor device as a user interface. In one specific embodiment, proximity sensor device is implemented to indicate an orientation change in a first way responsive to detected object motion along the sensing region in a first direction, and is further implemented to indicate an orientation change in a second way responsive to detected object motion along the sensing region in a second direction. Thus, a user can cause orientation changes of different ways through the use of object motions in different directions along the sensing region.

An image sensing system for a vehicle includes an imaging sensor comprising a two-dimensional array of light sensing photosensor elements formed on a semiconductor substrate. The imaging sensor is disposed at an interior portion of the vehicle, and may be at or proximate to an interior rearview mirror assembly of the vehicle. The system includes a logic and control circuit comprising an image processor for processing image data derived from the imaging sensor. The image sensing system may identify objects of interest based on spectral differentiation or by comparing over successive frames image data associated with objects in the forward field of view of the image sensor or by objects of interest being at least one of qualified and disqualified based at least in part on object motion in the field of view of the imaging sensor.

A control device for a vehicle or mechanism includes a portable displacement controller which permits a non-technical user to achieve effective control of the vehicle or mechanism, by moving the portable displacement controller intuitively with little learning effort. A first sensing device, attached to the displacement controller, detects the user's controlling motion. A second sensing device, attached to the object being controlled, detects motion thereof. An interface device receives signals from the sensing devices, processes those signals to determine relative motion of the controlling motion and the object's motion and outputs a control signal in accordance with the processed signals. The sensing devices each detect motion in six degrees of freedom; the sensing devices each include a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. In specific embodiments, the accelerometers, gyroscopes, and magnetometers include micro-electromechanical system (MEMS) devices.

A method of generating cursor motion signals for improved usability is provided. In one embodiment, the method comprises detecting object motion in a sensing region and providing cursor motion signals in accordance with cursor motion values generated responsive to continuation of the object motion in the inner region. This embodiment further comprises providing cursor motion signals configured to generate cursor motion that combines incremental cursor motion with additional cursor motion responsive to the object moving from the inner region into the outer region, where the incremental cursor motion comprises motion toward an edge of the display correlating to an edge of the sensing region proximate the object, and where the additional cursor motion comprises cursor motion indicated by cursor motion values generated responsive to continuation of the object motion in the outer region of the sensing region.

A noninvasive image measuring method of measuring internal organ / tissue temperature using an MRI system. Temperature measurement insusceptible to body motion and spatial variation of magnetic field is realized by utilizing the position and size of a temperature change region as a priori information to determine the phase distribution of the complex magnetic resonance signal of water proton at a given temperature point and by subtracting the phase distribution before the temperature change estimated (self-referred) from the phase distribution in the peripheral region for each pixel of the image, thereby eliminating the subtraction process of image before and after temperature change. The precision of temperature measurement can be enhanced by estimating a complex curved surface formed of the peripheral region in each temperature change region of the real-part and imaginary-part images of the complex magnetic resonance signal, and calculating the phase difference between an actually measured complex signal distribution and the estimated complex signal distribution of the complex signal distribution for each pixel, thereby reducing the estimation error due to phase transition from −π to +π occurring in a phase distribution. Furthermore, temperature can be measured through optimal imaging following up body motion by using an optical positioning system in combination even if the part being measured is shifted.
