摘要:
The present invention is a retractable/extendable diversity antenna that provides the appropriate polarization in a horizontal orientation. The antenna structure is placed within a Type II PCMCIA PC card package and may be extended or retracted with one touch. The antenna structure is large enough to provide for the diversity antenna design and may optionally be housed within a PCMCIA Type II PC Card. At least one spring-loaded mechanism is used to extend the antenna structure beyond the PCMCIA PC Card package and to provide stability while the antenna structure is in the extended position. The diversity antenna configuration may consist of either two miniature, planar antenna modules or two etched printed circuit board contours that are spaced as far apart as possible with a minimum separation of a quarter wave length distance in order to provide mitigation to radio multipath fading effects. The antenna modules have orientations perpendicular to each other such that the polar nulls representative of their radiation patterns remain spatially orthogonal.

A light matrix display system and a lamp socket for use therein. The lamp socket receives a single lamp which may be easily replaced by another lamp. The lamp socket is also designed so that it may be readily replaced if necessary. A solid state switching circuit is replaceably mounted on each lamp socket. Thus, if a switching circuit fails, it may be quickly replaced without disturbing the operation of other lamps. The light matrix display system includes a plurality of lamps arranged in rows and columns. A plurality of row control conductors and column control conductors are provided which are connected to a matrix system controller. Hot and neutral AC current supplying conductors and one row control conductor and one column control conductor are directly connected to each lamp socket and the switching circuit associated with the lamp socket. When proper voltages are placed on the row and column control conductors connected to a lamp socket, current flows through the solid state switching circuit, which turns on the corresponding lamp.

A surface-mount touch panel cradle is disclosed for use in electrically controlling remote components. The surface-mount touch panel cradle comprises a surface mounted receptacle. A cradle frame can be coupled to the receptacle. A frame biasing mechanism can be configured to move the cradle frame away from the information mount to enable the touch panel to be inserted and removed from the receptacle. An electrical connection can be located within the receptacle. The electrical connection can be configured to be electrically coupled to the touch panel.

A connector includes a modular housing having a jack slidably disposed thereto. The housing includes a substantially U-shaped frame having a cover mounted thereon. A printed circuit board (PCB) is secured to the frame and has an elongated center finger extending between the opposing side walls of the frame. A plurality of partially exposed contact lines are formed on the center finger of the PCB. The jack includes a slide plate having an aperture extending therethrough and a channel communicating with the aperture. The aperture is configured to receive a media plug. Mounted on the slide plate so as to be positioned over the channel is a pin block. The pin block has a plurality of elongated slots formed therein. The slots face the channel and are separated by insulating walls. Disposed within each of the elongated slots is a substantially S-shaped pin. Each pin has a tail end that is mounted to the pin block, a downwardly curved portion that extends within the channel, and an opposing lead end which is freely disposed within the aperture of the slide plate. The center finger of the PCB is slidably received within the channel of the slide plate such that the jack can be selectively moved between an extended position and a retracted position.

A system is disclosed for mounting a faceplate. The system includes a sub-plate configured to be coupled to a junction box. The sub-plate can have an interference-fit socket extending through the sub-plate. The interference-fit socket comprises one or more interference fingers located adjacent to a post opening. A post extending from the faceplate can be positioned and sized such that, as the faceplate is coupled to the sub-plate, the post will be received into the post opening in the interference-fit socket and engaged by the one or more interference fingers, enabling the faceplate to be securely mounted to the sub-plate.

An automatic discharge device comprises a housing adapted to receive a container therein. An actuator arm is attached to the housing and movable between first and second positions. The actuator arm includes a dispensing bore therein. A drive unit is provided for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch. The actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm.

The present invention relates to a removable and/or retractable extension for an electronic apparatus which is connected to the apparatus with a physically independent electrical connector which enables the extension to be retracted, extended, removed and replaced without connection or disconnection of wires, cables, plugs, jacks, flex connectors and similar devices which physically restrain the extension. Preferred embodiments of the present invention include longitudinally extensible conductors or leaf-spring conductors to provide a physically independent electrical connection between the retractable and/or removable extension and its host electronic apparatus. The extensions of some embodiments of the present invention include antennas, physical/electrical media connectors and similar electrical and electronic devices.

A communications card, which preferably conforms to the PCMCIA requirements for a Type III PC card, includes a housing formed by a top cover and a bottom cover. An opening is formed in the housing of the communications card sized and the opening is sized and configured to receive a RJ series connector plug such that no portion of the plug extends through either the top surface or the bottom surface of the communications card. In particular, a portion of the top cover defines an upper portion of the opening and a portion of the bottom cover defines a lower portion of the opening. Preferably, the distance from the top surface to the bottom surface of the communications card is generally equal to or less than about 10.5 mm. Additionally, a distance that is generally equal to or less than about 10.1 mm separates the inner upper surface of the opening from the lower inner surface of the opening.
