    Abstract: An electronic device may be provided with slot antennas. A slot antenna may be formed from metal structures that have a dielectric gap defining an antenna slot. The metal structures may include multiple metal layers that overlap a plastic antenna window and that serve as capacitive electrodes in a capacitive proximity sensor. The metal structures may also include a metal electronic device housing. The metal electronic device housing and the metal layers may be formed on opposing sides of the antenna slot. The metal layers may have a notch that locally widens the antenna slot at an open end of the antenna slot. One of the metal layers may be shorted to the metal electronic device housing at an opposing closed end of the antenna slot. The antenna slot may be indirectly fed using a near-field-coupled antenna feed structure such as a metal patch that overlaps the antenna slot.

  • Patent number: 8941390
    Abstract: A test system for medical devices that does not require physical contact with an electrical site along a conductive path is described. Not having to physical contact an electrical site while performing an electrical continuity test avoids potential damage to the site. The test system includes a fluidic channel that dispenses an electrolytic solution onto a first electrical site on the conductive path. A light source irradiates the first site to thereby induce a photoelectrochemical (PEC) effect at an interface thereof. The PEC effect produces a change in both the potential (i.e., voltage) and current carrying ability in the conductive path. That voltage or current is measured at a second site to determine whether there is electrical continuity or discontinuity between the sites on the conductive path.
