Abstract:
An electronic device comprises a planar dielectric member 44 with at least one antenna trace 48 formed on it. The device may include a touch sensitive screen display with touch sensors 80 mounted on the planar dielectric member 44 with light controlling means to form images on the display. The planar dielectric member 44 may include at least one planar glass member. The display may have an active region with capacitive, touch sensing, indium tin oxide electrodes 80 and an inactive region, with no sensors, which may be used to locate at least one antenna trace 48. The antenna trace 48 may be made of metal, copper or indium tin oxide. A loop antenna trace may be formed around the touch sensing electrodes. Opaque regions of the display screen may be used to conceal at least one antenna trace 48. Alternatively, the device may include a touch panel with touch sensing electrodes 80 formed on the planar dielectric member 44. Otherwise, the device may include a display involving the planar dielectric member where at least one antenna trace 48 is located in an inactive portion of the display which is coupled to an integrated circuit radio frequency transceiver mounted on a circuit board. The device may be a computer or various handheld devices and may use various resilient connection means to various types of antenna.
Abstract:
A battery cell core is hermetically sealed inside a casing, with conductive paths formed in the casing that individually connect cell subsets of the core to a battery management circuit for detecting individual failing cell subsets and for changing the battery output voltage by forming series/parallel connections between the cell subsets. In one version, the casing has a metal can with an opening of the can being sealed by a non-conductive cap that is sealed and bonded along its periphery to the can walls. In one aspect, the cap has edge metallization along its periphery where it is sealed to the can walls. In another aspect, the conductive paths are formed in the non-conductive cap. Various other embodiments are also described and claimed.
