Abstract:
An electronic device comprises a housing (2) having an outer face (11) and an inner face (12). A key is provided on the housing (2), which comprises a micro hole (21, 22) formed in the housing (2) and a conductive material (23, 24) extending within the micro hole (21, 22) to the outer face (11) of the housing (2). A sensor (6) is coupled to the conductive material (23, 24) to detect whether an object is brought into contact or out of contact with the micro hole (21, 22) at the outer face (11).
Abstract:
An electrical interconnection system includes a printed circuit board having a receiving cavity therein. At least one circuit trace is located on a side wall of the cavity. An electrical connector is configured for insertion into the receiving cavity. The electrical connector has an electrical contact positioned to contact the at least one circuit trace when inserted into the receiving cavity.
Abstract:
The present invention pertains to a data medium in the form of a chipcard comprising the card body (1) fitted with an antenna (3), a chip module (2) containing an integrated circuit (10) and located in a recess (5) provided in the card body (1). The electric connection between the antenna (3) and the chip module (2) passes through lows (11) in the antenna (3) connections (4). When manufacturing the inventive data medium, a cavity (5) is engineered inside the body card (1) in which the antenna is at least partially embedded. The chip module (2) is placed into said cavity (5) and glued to the card body, for example with a thermoactivable glue (6), thereby establishing an electric connection between the chip module (2) and the antenna (3) inasmuch, for instance, as a conductive glue is used for anticipated application to the free antenna (3) connections (4). In the preferred embodiment the chip removal is carried out so as to form an oblique cutout.
Abstract:
Described examples include a gas cell (201), including a cavity (203) in a first substrate (202), a nonvolatile precursor material in the cavity (203), and a second substrate (206) bonded to the first substrate (202) to seal the cavity (203). The precursor material is activated after or during forming the sealed cavity (203) to release a target gas inside the sealed cavity (203).
Abstract:
The invention relates to circuit boards and to screening circuits and components on such boards from stray rf interference when they are mounted as arrays or stacks of such circuit boards. The- circuit boards (12, 14) are individually screened by conductive screening layers (16, 18) as known in the art and the individual screening layers are coupled together by layered interconnects (34) which connect corresponding screening layers (16, 18) of the individual circuit boards (12, 14) together, instead of by vias.
