The reception device includes a signal generation unit configured to generate a register signal for controlling a first clock signal transmitted from the transmission device based on a comparison result obtained by comparing a reference clock signal with one of the first clock signal and a second clock signal which is based on the first clock signal; and a register signal transmission unit configured to transmit the register signal generated by the signal generation unit to the transmission device.

An endoscope includes a control module, a lens module, a cover, and an encapsulation. The lens module is electrically connected to the control module. The cover has a transparent area, and the cover covers the lens module in a sealing manner. The encapsulation encapsulates the cover and the control module, and exposes the transparent area, such that the encapsulation serves as a shell of the endoscope.

The present invention relates to the process of using signal-emitting and/or receiving objects or smart medical devices for image acquisition, and which can utilize a variety of external energy sources which are directly applied and/or incorporated into the host subject to produce a continuous and dynamic visual representation of the host subject on a computer display, which representation hereafter will be referred to as a visualization map. The derived images can be targeted, to small (i.e., focal) areas of clinical interest, to organ systems, or the entire body. The present invention provides a scalable method for continuous and dynamic imaging over prolonged periods of time, as dictated by the clinical context.

An image processing apparatus performs image processing based on image data and ranging data output from an image sensor. The ranging data represents a distance between the image sensor and a subject. The image sensor is configured to receive reflected light of illumination light reflected from the subject and to output the image data and the ranging data. The image processing apparatus includes a processor configured to: calculate a parameter of the illumination light emitted onto a point on the subject, based on the ranging data; calculate a parameter of the reflected light, based on a gradient of a depth on the point on the subject calculated from the ranging data; and calculate the distance between the image sensor and the subject in a direction orthogonal to a light-receiving surface of the image sensor, based on the image data and the parameters of the illumination light and the reflected light.

A position detection system includes: an object to be detected having a magnetic field generator to generate a position detecting magnetic field, and configured to be introduced into a subject; detection coils, each being configured to detect the position detecting magnetic field to output a detection signal; and a processor including hardware. The processor is configured to: correct measured values of detection signals output from the detection coils using a magnetic field generated by applying the position detecting magnetic field to a metal plate, the metal plate being disposed on a side opposite to an area to be detected of the object to be detected relative to the detection coils; and calculate at least one of a position and a direction of the object to be detected using the corrected measured values of the detection signals.

Methods and apparatus to form biocompatible energization elements are described. In some examples, the methods and apparatus to form the biocompatible energization elements involve forming cavities comprising active cathode chemistry. The active elements of the cathode and anode are sealed with a biocompatible material. In some examples, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.

Methods and systems for manufacturing a swallowable sensor device are disclosed. Such a method includes mechanically coupling a plurality of internal components, wherein the plurality of internal components includes a printed circuit board having a plurality of projections extending radially outward. A cavity is filled with a potting material, and the mechanically coupled components are inserted into the cavity. The cavity may be pre-filled with the potting material, or may be filled after the mechanically coupled components have been inserted therein. A distal end of each projection abuts against a wall of the cavity thereby preventing the potting material from covering each distal end. The cavity is sealed with a cap causing the potting material to harden within the sealed cavity to form a housing of the swallowable sensor device, wherein the distal end of each projection is exposed to an external environment of the swallowable sensor device.

A capsule endoscope system includes: a capsule endoscope; a receiving unit that receives an image signal of an object transmitted wirelessly from the capsule endoscope; an image display unit that displays an image based on the image signal received by the receiving unit; a position detection unit that detects a position of the capsule endoscope; and a control unit having a first determination unit that determines whether normal display of the image based on the image signal is possible and having a second determination unit that determines whether normal position detection for the capsule endoscope is possible by the position detection unit. The control unit causes the image display unit to start display of the image based on the image signal when the normal display of the image based on the image signal is possible and the normal position detection for the capsule endoscope is possible.

The present disclosure relates to a solid-state imaging element and electronic equipment that make it possible to sufficiently secure a time width of a pulse signal. In an AD converter for each unit pixel, a pulse generation circuit feeds back a delay signal obtained by delaying an output signal of the comparator to the comparator and arithmetically operates the output signal and the delay signal to generate a pulse signal. A latch circuit latches the pulse signal generated by the pulse generation circuit. The present disclosure can be applied to a solid-state imaging element of a stacked type and a back side illumination type.
