Patent number: 12101887Abstract: In an embodiment, a method of manufacturing (100) is described. The method comprises providing (102) a first layer defining a first inner surface (203a) and a first outer surface (203b), a second layer defining a second inner surface (205a) and a second outer surface (205b), and an electrical component (206) positioned on the first inner surface or the second inner surface. The method further comprises attaching (104) the first and second layers together to create a device (200) comprising the first and second layers, wherein the first outer surface and the second outer surface define an external surface of the device.

Patent number: 9957288Abstract: The present invention relates to compounds which can be used to control plant development. Indeed, the present invention discloses a new class of pyrabactin analogues which have a physiological effect on—for example—seed germination, and/or stomatal closure, and/or have developmental effects on root and shoot development and organogenesis. Hence, the latter compounds can be used to control plant development such as—for example—increasing the tolerance of plants to drought stress or to control physiological phenomena such as pre-harvest sprouting, tolerance to pathogens etc.Type: GrantFiled: January 27, 2015Date of Patent: May 1, 2018Assignee: Universiteit GentInventors: Christian Stevens, Danny Geelen, Thomas Heugebaert, Inge Verstraeten
