An infrared emitter (34) at least partially defines an interior space that at least partially contains convective products of combustion. A burner (32) provides a mixture of combustible gas and primary air to the combustion, while secondary air is also provided to the combustion. A first side of the infrared emitter is in opposing face-to- face relation with the interior space so that the first si...

Embodiments of the present disclosure provide methods, devices, modules, and systems for memory cell sensing using negative voltage. One method includes applying a negative read voltage to a selected access line of an array of memory cells, applying a pass voltage to a number of unselected access lines of the array, and sensing whether a cell coupled to the selected access line is in a conductive ...

A device (10) for adjusting and controlling the rotation speed of an engine cooling fan (VNT). The device (10) has an actuating device (40) which, on command, axially pushes a movable half-pulley (31B) of a device (30) with a pulley (31), to vary the velocity ratio between a drive shaft (AM) and a driven shaft (AC) fitted with the fan (VNT). The actuating device (40) has two cams (CM1, CM2) rotate...

An electromagnetically activatable pulley assembly (1) for selectively driving a rotating shaft (51), comprising a drive pulley (3), an electromagnet (6), and a clutch (8) adapted to maintain the pulley engaged on the shaft (51) and to disengage the pulley (3) from the shaft (51) upon energizing said electromagnet (6); the clutch includes a hub (20) rigidly fixed to the shaft (51), an armature (9)...

A pulley assembly defines an axis (A) and includes a support (17) resilient in an axial direction adapted to be connected to a control shaft of an accessory, an annular element (3) arranged between the resilient support (17) and a fixed element (4), preferably the accessory, and having connecting means (24) adapted to be connected to the fixed element (4), a pulley (5) rotatable about said axis (A...

The present invention discloses a gel mat and a method for manufacturing the same. The purpose thereof is to provide a gel mat which features simple manufacturing process, low cost, ease of use, high reliability, and freedom from possible damage in case of being pierced or depressed with a pressure, and a method for manufacturing the same. The gel mat includes a hermetically sealed bag which is co...

An actuator is disclosed which is required to implement, without errors, a generic rate-based packet sending algorithm over a packet switching network such as the Internet. Typical applications are audio/video streaming over UDP or TCP, audio/video conference over IP, Voice over IP, real-time data delivery, IP Television, Digital Video Broadcast over IP, client-server or peer-to-peer content distr...

The invention regards a selector lever for pushing down the jacks of a textile knitting machine, comprising a cam contact surface able to push the jacks into a rearward position, that on such contact surface there is an upper lever repelling chamfer facing upwards and a lower working chamfer facing downwards. Said chamfers converging towards the heel so as to form a coupling ridge of the heel so t...

The invention relates to a Jack selector unit (100) for textile knitting machines, comprising a plurality of selector tips (20), each oscillating around an oscillation pin (22) between two extreme positions in relation to a central, neutral position, and a plurality of piezoelectric laminae (30) each of which operatively connected to a respective selector tip (20), and electrically operable to cau...

An essential oil diffuser for motor vehicles of the type adapted to be placed on the air vents, having an outer shell which receives a bottle containing the essential oil to be diffused in the interior compartment by the air stream coming from the vents, which flows over a wick soaked in said bottle and carries a certain amount of evaporated essential oil in suspension.
