The present invention relates to an ultrasound-based system for localizing a medical device within the field of view of an ultrasound imaging probe. A localization system is provided that includes at least three ultrasound emitters that are arranged on a frame; and a position triangulation unit. The frame is adapted for attachment to an ultrasound imaging probe. The position triangulation unit determines a spatial position of the ultrasound detector relative to the at least three ultrasound emitters based on signals received from an ultrasound detector that is attached to the medical device. The frame includes a detachable reference volume comprising a background volume and an inclusion or void. When the detachable reference volume is attached to the frame and the frame is attached to the ultrasound imaging probe the inclusion or void provides a corresponding image feature within the field of view of the ultrasound imaging probe for use in calibrating the field of view of the ultrasound imaging probe with the coordinate system of the localization system.

A positioning method using music pieces continuously provides positioning service. At each signature burst (i.e., a highly unique short musical segment suitable for positioning), sounds of a music piece are used for positioning. Between signature bursts, dead reckoning (DR) is used.

A tool for detecting leaks in downhole pipe comprises wave generator devices (30, 40) for coupling ultrasound waves into the surrounding fluid. The waves are scattered, e.g. reflected, at inhomogeneities (60) in the fluid, for example particles, scatterers and/or water in oil, thereby generating reflections (70) which are measured with a receiver device (25) and evaluated for determining the positions of the inhomogeneities in the fluid in order to detect e.g. crossflows (15) generated by leakage (65).

An imaging apparatus and a positioning apparatus that include an imaging unit for imaging a detected part of a body to be detected; and a distance positioning unit having at least two signal positioning devices, i.e., a signal generator and a signal detector, wherein one signal positioning device is arranged at the detected part, the other signal positioning device is arranged at a position where a predetermined position relationship exists relative to the imaging unit. The position of the detected part in at least one direction in a three-dimensional space relative to the imaging unit is obtained according to a measured distance between the two signal positioning devices. The imaging apparatus and the positioning apparatus reduce pre-positioning imaging sequence workload, and the risk of radiation on the body to be detected is avoided.

A method and system for enabling the determination of a position of a receiver within a space includes transmitting a beacon signal from each of a plurality of beacon devices located at different locations within the space. The beacon signal transmitted from each beacon device has a unique information component and may have a unique frequency pattern of multiple frequencies. Each beacon signal can be distinguishable from the beacon signals transmitted from any other of the beacon devices based on the combination of its unique information component and its unique frequency pattern. The beacon signals are received at a receiver. At the receiver, for each beacon signal of a working subset, time-delay information of the received beacon signal is determined and multilateration is applied to determine the position of the receiver based on the location of each beacon device of the working subset.

The present technology relates to a control device, a control method, and a program which enable easy detection of contact of an object with a predetermined surface in a case where the object is gripped and arranged on the predetermined surface.

In a case where a target object gripped by a finger portion including an ultrasonic transmitting element that generates an ultrasonic wave and a finger portion including an ultrasonic receiving element that receives the ultrasonic wave output from the ultrasonic transmitting element is to be arranged on an arrangement surface, a detection unit 104 detects contact of the target object with the arrangement surface on the basis of a sound pressure of the ultrasonic wave received by the ultrasonic receiving element. The present technology can be applied to, for example, a control device for a robot and the like.
