A sortation conveyor for transporting and diverting a plurality of articles includes a first conveying path and a second conveying path angularly positioned relative to the first conveying path. A plurality of pusher elements may be selectively diverted laterally across the first conveying path to divert articles to the second conveying path. A piezoelectric actuated switch assembly positioned adjacent to the second conveying path selectively engages the pusher elements to divert the selected article to the second conveying path.

A damper assembly includes a housing and rod supported by the housing. A piston assembly is attached to the rod, and is positioned to separate an interior chamber of the housing into a first fluid chamber and a second fluid chamber. The piston assembly includes an annular plate that defines at least one orifice. The orifice interconnects the first fluid chamber and the second fluid chamber in fluid communication. The damper assembly includes a piezoelectric device that is moveable between a disengaged position and an engaged position, in response to a control signal. When disposed in the disengaged position, the piezoelectric device does not affect fluid flow through the at least one orifice.

In a method of manufacturing a piezoelectric device in which a piezoelectric thin film on which functional conductors are formed is fixed to a support substrate by a fixing layer, an alignment mark is formed on one main surface of a light-transmitting piezoelectric substrate. A sacrificial layer is formed on a main surface of the piezoelectric substrate with reference to the alignment mark and the fixing layer is formed so as to cover the sacrificial layer and is bonded to the support substrate. The piezoelectric thin film is formed by being separated from the piezoelectric substrate and the functional conductors are formed on the surface of the piezoelectric thin film with reference to the alignment mark. The piezoelectric device is able to be manufactured while positions of formation regions of conductors are adjusted efficiently.

A system and method provides a piezoelectric stack arrangement for reduced driving voltage while maintaining a driving level for active piezoelectric materials. A stack arrangement of d36 shear mode single crystals of both air X-cut and Y-cut ±1:45° (±20°) arrangement are bonded with discrete conductive pillars to form a shear crystal stack. The bonding area between the neighboring crystal parts is minimized. The bonding pillars are positioned at less than a total surface are of the single crystal forming the stack. The stack fabrication is facilitated with a precision assembly system, where crystal parts are placed to desired locations on an assembly fixture for alignment following the preset operation steps. With the reduced clamping effect from bonding due to lower surface coverage of the discrete conductive pillars, such a piezoelectric d36 shear crystal stack exhibits a reduced driving voltage while maintaining a driving level and substantial and surprisingly improved performance.

More in particular, the present invention relates to a piezoelectric device (1, 101) comprising at least two carbon fibre crossed yarns (2a, 2b; 102a, 102b), at the intersection of which a zinc oxide layer (3, 103) in nanorod form is arranged, wherein an end (4a, 4b) of each of said yarns (2a, 2b; 102a, 102b) is connected to an operative unit (5).

A MEMS piezoelectric device includes a monolithic semiconductor body having first and second main surfaces extending parallel to a horizontal plane formed by first and second horizontal axes. A housing cavity is arranged within the monolithic semiconductor body. A membrane is suspended above the housing cavity at the first main surface. A piezoelectric material layer is arranged above a first surface of the membrane with a proof mass coupled to a second surface, opposite to the first surface, along the vertical axis. An electrode arrangement is provided in contact with the piezoelectric material layer.

A monolithic integration of phase change material (PCM) switches with a MEMS resonator is provided to implement switching and reconfiguration functionalities. MEMS resonator includes a piezoelectric material to control terminal connections to the electrodes. The PCM is operable between an ON state and an OFF state by application of heat, which causes the phase change material to change from an amorphous state to a crystalline state or from a crystalline state to an amorphous state, the amorphous state and the crystalline state each associated with one of the ON state and the OFF state.

Disclosed is a piezoelectric material including stereocomplex crystals of poly(D-lactic acid) (PDLA) and poly(L-lactic acid) (PLLA), wherein poly(D-lactic acid) and poly(L-lactic acid) are crystallized into a stereocomplex, thus exhibiting superior heat resistance and piezoelectric properties. This piezoelectric material, which is obtained using poly(lactic acid), can be produced at very low cost compared to when using PVDF, and is configured to include stereocomplex crystals of PDLA and PLLA and can thus manifest high thermal stability and piezoelectric properties, compared to when using conventional PLLA alone. Such a piezoelectric material can be efficiently utilized in a variety of fields in which low production cost, high processing temperature in the manufacturing process, or high-temperature stability of piezoelectric material products is required.

I have a really romantic view about taking my child to a festival. The reality is very different. We went to Let’s Rock last week. She is of course bored by the time we reach 2 metres past the entrance, but I persevere and blow up an air lounger which entertains her for approximately 5 seconds because she has her own personal bouncy castle. But, after she has fallen into 10 people and knocked over five drinks, it's time to put it away. This will carry on for approximately five hours while I try and drink a pint of cider and watch a band.

The 'Big Little Lies' actress, who portrayed Christina in the film franchise, makes the confession during an appearance on the Armchair Expert with Dax Shepard podcast.

Een onderzoeksbureau heeft geen grensoverschrijdend gedrag vastgesteld bij de vroegere Denk-fractievoorzitter Kuzu. Dat zegt de huidige fractievoorzitter Azarkan na onderzoek door het bureau Integis.

Binnen Denk woedt een machtsstrijd, die voor een deel te maken heeft met de positie van Kuzu. Die stapte in maart op als fractievoorzitter, naar later bleek in verband met de nasleep van berichten over een eerdere buitenechtelijke affaire met een vrouw.

Kuzu beschuldigde partijvoorzitter (en fractiegenoot) Öztürk van een poging tot politieke broedermoord omdat hij verhalen over de affaire naar buiten zou hebben gebracht. De discussie spitste zich erop toe dat Kuzu grensoverschrijdend gedrag zou hebben gepleegd.

Bureau sprak niet met de vrouw

Na het opstappen van Kuzu werd Azarkan fractievoorzitter en die heeft een onderzoek laten instellen. Daarvan zijn nu dus de resultaten naar buiten gekomen. Volgens Azarkan heeft het bureau Integis omgevingsonderzoek gedaan, openbare bronnen geraadpleegd en interviews afgenomen. De vrouw heeft geen aangifte tegen Kuzu gedaan. Volgens Azarkan was de vrouw niet bereid aan het onderzoek mee te werken en "feiten te presenteren om de door haar in de media geuite beschuldigingen te staven."

Azarkan stelt dat er nu duidelijkheid is, en dat de beschuldiging van grensoverschrijdend gedrag niet kan worden gestaafd. Hij vindt dat het partijbestuur onder leiding van voorzitter Öztürk al in 2018 onderzoek had moeten doen. Kuzu zelf zegt zich door de uitkomsten van het onderzoek gesterkt te voelen. Hij benadrukt dat hij de beschuldigingen over grensoverschrijdend gedrag steeds pertinent onwaar heeft genoemd. "Ik ga met alles wat ik in mij heb door met het vertegenwoordigen van onze kiezers", voegt hij eraan toe.

Overigens loopt er ook nog een ander onderzoek naar de gang van zaken. Dat is niet ingesteld door de fractie, maar door het partijbestuur onder leiding van Öztürk. Het bestuur zette Azarkan deze week uit de partij, maar deze is niet van plan zijn werk neer te leggen. Kuzu steunt Azarkan.

...this feels like the album that brings all the talents together.
