Abstract: The conventional surveillance angle, in which activities are observed from a helmet camera mounted at the top, separates a participant of an activity, such as sports, from his immediate experience. A different point of view can be taken from the camera when it is mounted via the Y-shaped accessory mount over the apogee of the helmet chin bar. This point of view is a sousveillance in which the observation is down at a human level so as to allow a consumer of the recorded contents of the sousveillance to connect with the sportsman by vicariously undergoing the immediacy of his sporting experience.

Abstract: The invention relates to an image acquisition device enabling a dental radiological image to be obtained, the device comprising a matrix sensor (C) having integrated therein a plurality of image acquisition photodiodes (DA) sensitive to irradiation and at least one detection photodiode (DD) also sensitive to irradiation, the device also comprising a control module (M) for controlling the sensor (C) and suitable for periodically reading the detection photodiode (DD) and for causing the sensor (C) to change over (SBA) between at least two modes: a standby mode and an acquisition mode (ACQ).

Abstract: A rigid, rod-shaped endoscope for medical applications includes a distal end having a light-permeable distal window and a light outlet disposed adjacent to the distal window, which includes a device configured to prevent the incidence of stray light onto sides of the deflection prism facing the distal window. An endoscope shank includes a plurality of telescoping hollow tubes. An inner fixed optical tube includes a moveable optical deflection prism and an optical system configured to transmit light beams. The optical deflection prism is mounted rotatably on a shaft that is disposed at a right angle to a longitudinal axis of the endoscope. At least one moveable sliding tube is configured to move relative to the inner fixed optical tube in the direction of the longitudinal axis of the endoscope using magnetic forces generated by a plurality of moveable permanent magnets.

Abstract: A medical gas insufflation device comprising at least a gas outlet circuit, a connector for connecting a pressurized vessel in which the gas is packaged, an expander placed between the connector and the gas outlet circuit, a high-pressure sensor placed between the connector and the expander, a flow meter placed at the outlet from the expander, and a microprocessor connected at least to the sensor to receive signals representative of the pressure observed at the connector and to the flow meter to receive signals representative of the flow rate at the outlet from the expander, wherein the microprocessor includes evaluation means for evaluating the remaining volume of gas after expansion as a function of the signals received from the sensor and the flow meter during a gas expansion operation.

Abstract: The medical, particularly dental imaging camera including an elongated housing (2) that can be held by a single hand of a user and provided, at its front end, with an imaging element, this housing (2) including a sensitive control element capable of freezing, on a display (5), an image selected by the user, this control element having a detection area (9) situated on the housing (2) that is delimited by a surface discontinuity such as a recess or a relief (11). The housing (2) encloses a sensor element associated with an electronic driving circuit and an electrostatic foam element whose one end is applied against the sensor element and whose opposite end is applied against an area of the inner face of the housing (2) located to the right of the detection area (9).

Abstract: Method for detection and location of a difference in density and/or structure and/or chemical composition of a biological tissue (7) which is subjected to continuous illumination in a first determined band of frequencies, causing the former to generate a phenomenon of fluorescence, autofluorescence or luminescence in a second band of frequencies. The method includes the following stages: the biological tissue thus illuminated is visually captured by color video elements provided with image sensors with a mosaic of pixels provided with additional color filters; for each image point thus obtained 1) information relating to the energy received by each pixel is collected in order to reconstitute an image of the biological tissue (7), b) amplification occurs for the signal corresponding to the energy received in the second frequency band in order to characterize the biological tissue (7) difference or to cause the image thus obtained to appear.

Abstract: This system for dental X-ray image acquisition comprises an X-ray generator and a control module for controlling an intra-oral sensor. The module includes means for sending a command to the generator in application of at least one predetermined criterion for preventing, stopping, or modifying the power of X-ray emission. The use of this system for optimizing the quantity of X-rays received by a patient.
