Abstract: Described herein are systems and methods for maintaining a wireless connection to a remote server while a device is in a low power mode. As a result of maintaining the connection, the device can receive messages triggering a wakeup event and placing the device in a normal power mode, enabling the device to be controlled remotely. To maintain the connection, the device transitions from sending encrypted network messages to a server from a first interval while in the normal power mode to a second interval while in the low power mode. In addition, the device sends unencrypted network messages to the server at the first interval using low power circuitry. The low power circuitry receives messages from the server and may trigger the device to enter the normal power mode and/or a connection maintenance mode.

Abstract: The present disclosure relates to a method and device for producing a dental component. The method includes: a) providing a piece of material attached to or held by a first holder; b) shaping the piece of material to form the dental component and at least one support pin maintaining the dental component attached to the first holder or the initial piece of material; c) engaging a second holder to the dental component while the dental component still is attached to the first holder or the initial piece of material via the at least one support pin; and d) removing the at least one support pin from the dental component while the dental component is engaged by the second holder.

Abstract: The present invention provides a novel apparatus to grow cells where the cultivation chamber (1) is partially filled with liquid cultivation medium and cells. Mixing and aeration is achieved by generating intermittently one single large gas bubble (6) at the bottom of the column bioreactor, the single large bubble width representing from 50 to 99% of the tank width, preferably from 60 to 99%, more preferably 98.5%. The culture medium flows out as a film between the large bubble and the inner wall of the bioreactor. This rising bubble allows mixing and aeration of the bulk. As the design of the invention is very simple, it is possible to manufacture it with flexible plastic material and use the apparatus as a disposable system. Moreover, such a mixing/aeration principle minimizes cell damages usually due to shear stress and small bubbles and allows easy and efficient scale-up from small scale to a larger one. Such a large-scale, efficient and disposable culture system can largely reduce production costs.

Abstract: A rotary wing blade of limited taper ratio, comprising in succession along a reference radius: an inner zone; a forward-swept zone; and a back-swept zone. In addition, the beginning of the forward-swept zone lies in the range 0.47 to 0.65 times the reference radius R of the rotary wing. Furthermore, the leading edge of the blade at the reference radius presents an angle ? lying in the range ?40° and ?65° relative to the general axis of the blade.

Abstract: The rotary flap (1) is liable to turn about a longitudinal axis of rotation (4) defined according to the first span (5) of said flap (1), said flap (1) having a profile (6) extending along the chord (CO) and comprising a first leading edge (7), a first trailing edge (8), an inner surface (9) and an outer surface (10), The inner surface (9) and outer surface (10) have non-concave shapes, first leading edge (7) having a rounded shape provided with a curve radius (R) more or less constant or elliptical in shape whose first major axis to minor axis quotient is less than or equal to 1.5, with first trailing edge (8) having a main angle (?) that is included between 10° and 30°, and axis of rotation (4) is situated at a first distance (C1) from first leading edge (7), that is included between 15% and 35% of the chord (CO) of flap (1).

Abstract: A lifting surface with a rotary flap liable to turn about a longitudinal axis of rotation defined according to the first span of the flap, the flap having a profile extending along the chord and including a first leading edge, a first trailing edge, an inner surface and an outer surface. The inner surface and outer surface have non-concave shapes. The first leading edge has a rounded shape provided with a curve radius more or less constant or elliptical in shape whose first major axis to minor axis quotient is less than or equal to 1.5. The first trailing edge has a main angle that is included between 10° and 30°. The axis of rotation is situated at a first distance from the first leading edge, that is included between 15% and 35% of the chord.
