The structural electrodes comprised an elastomeric column and distributed microelectrodes between the column and piezoelectric film.

In addition, two opposite output signals from different sides of the column can differentiate the force direction as the column is bent by external force. The resulting signal for sensing force and its direction depends on the size of column.Type: ApplicationFiled: February 13, 2009Publication date: August 19, 2010Applicant: Southern Taiwan UniversityInventor: Cheng-Hsin Chuang

Publication number: 20100207499Abstract: Water or air is directed through a hood or double cylinder cooling device for providing cooling to one or more light bulbs used in growing plants in greenhouses, aquarium, and hydroponic applications. A water recirculation system with a reservoir and a pump may provide a flow of cooling water through tubing to the hood. The hood provides a housing and a tube which contains one or more light bulbs which can be accessed or replaced through an end of the tube which projects through the housing. The light holder includes an enclosed electric box and a plurality of curved fins which expand against the inside glass tube. Various reflector housing shapes and reflectors direct light to plants. The end cap is bolted to a split ring flange attached to the outer tube.Type: ApplicationFiled: September 21, 2007Publication date: August 19, 2010Inventors: Stephen B. Keen, Thomas E. Marex

Publication number: 20100207504Abstract: A capped lamp/reflector unit (1) comprising a lamp vessel (2) arranged inside a reflector (3) and a lamp cap (4) fixed to the reflector. Electrical contacts (17) are provided substantially opposite to each other on an outer surface (24) of the lamp cap. The lamp cap comprises a first (25) and a second mating and engaging part (26), preferably identical to each other. The mating parts, when assembled, cannot move relative to each other and preferably are held together by the electrical contacts (17), which for this purpose are formed as spring clamps (39). The reflector is provided with a metal sheet cladding (22) on an outer surface (23) of the reflector. Furthermore, a transparent plate (34) is provided to close the light emission window (21) of the reflector. Thus, an easily replaceable, simple and safe capped lamp/reflector unit is obtained.Type: ApplicationFiled: October 20, 2008Publication date: August 19, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Teunis Adrianus Kassenaar, Greta Joanna Maria S'Heeren
