Abstract: A method and system of monitoring fluid flow in a wellbore. One or more space-distributed temperature input pulses are induced into at least a portion of a fluid in a housing in the wellbore. The housing has at least one cavity and one or more flow ports. A temperature response pulse, caused by the temperature input pulses, are sensed at one or more locations downstream of the cavity and a flow rate of the fluid through the cavity is determined. The flow rate may be determined based on one or more characteristics of the temperature response pulse, and a Retention Time Distribution (RTD) of the cavity.

Abstract: A method and system of monitoring fluid flow in a wellbore (16). One or more space-distributed temperature input pulses (6a,b; 6?; 6?) are induced into at least a portion of the fluid in a housing (15; 15a,b; 15?; 15?) in the wellbore, The housing has at least one cavity (14; 14a,b) and one or more flow ports (4; 4?. 5; 5?; 5a?,b?). A temperature response pulse, caused by said temperature input pulses, are sensed at one or more locations (2) downstream of said cavity (14; 14a,b) and a flow rate of said fluid through said cavity (14) is determined. The flow rate may be determined based on one or more characteristics of said temperature response pulse, and the Retention Time Distribution (RTD) of said cavity.

Abstract: Exterior element for a wristwatch middle part, wherein said exterior element takes the form of a separate cover plate which is fixed to the wristwatch middle part and at least partially covers a connection area between a bracelet strand and the watch middle part.

Abstract: The wristwatch includes a case (3) carrying at least one watch movement and at least one display (7, 17) for the current time and for other time related or non-time related information. The case (3) is fixedly or rotatably mounted at the end of an additional strand (10), made in one or more parts (14, 16, 18), comprising locking/unlocking means (19, 29) allowing the watch to be unfolded inside the hand.
