    摘要: The present invention proposes a portable barometric altimeter (10) including a pressure sensor (14), a calculation unit (16) which determines an altitude value (H) as a function of the pressure (P) measured by the sensor (14) and as a function of a reference temperature (T0) corresponding to an estimate of the temperature of the air mass at sea level, and a time measuring unit (18) that supplies calendar data (D), characterized in that it includes a correction circuit (32), which selects the reference temperature value (T0) from among a series of values (TS) contained in a database stored in the altimeter (10), as a function of the date (D) and as a function of a predefined climate value (C). The invention also proposes a method of determining altitude (H).

    摘要: The invention concerns a method allowing an electronic watch to automatically exit an altimeter mode including the following steps: (a) entry into altimeter mode by activating the watch altimeter module; (b) using a pressure sensor of the watch to measure at least one first pressure value used to calculate a first altitude value; (c) using the pressure sensor to measure at least one second pressure value used to calculate a second altitude value; (d) comparing the difference between said first and second pressure or altitude values to a determined pressure or altitude variation threshold using a variation detector of the altimeter module; (e) automatic exit from the altimeter mode when the result of the comparison is higher than the determined pressure or altitude variation threshold and stopping the display of altitude values by the analogue display means.

    摘要: An apparatus is provided for indicating the presence of pressure within a collection chamber of a device such as a chest drainage device. The apparatus includes a bladder configured to be positioned within the collection chamber or within another chamber in fluid flow communication with the collection chamber. The bladder has a concavity formed therein and configured to contract or expand in response to pressure in the collection chamber. The apparatus also includes surfaces associated with the bladder that are configured to move with respect to one another upon contraction or expansion of the concavity of the bladder, thereby indicating pressure within the collection chamber.
