Definitions

  • This invention relates in general to printed circuit boards, and more specifically, a printed circuit board that may be selectively positioned in one of a plurality of shapes for inclusion within a housing for a device such as a pager that may be manufactured in many forms.
  • Printed circuit boards conventionally have comprised a flat, rectangular, rigid or flexible material on which various electronic circuit elements, i.e., transistors, resistors, and capacitors, are placed. Electrical connections between these circuit elements are made by metal flows on the printed circuit board or by wire directly between the circuit elements.
  • electronic circuit elements i.e., transistors, resistors, and capacitors
  • Electronic system devices such as selective call receivers including pagers, typically are manufactured in many different shapes to fulfill different user requirements.
  • pagers are manufactured in the approximate shape of a cigarette pack for attachment to a belt, in the shape of a pen for attachment to a shirt pocket, or in the shape of a credit card for insertion into a shirt pocket.
  • Each of these different shaped pagers typically require substantially the same components, i. e., speaker, battery, antenna, switches, printed circuit board for the electronic circuit elements, and a display device. Because of the different shape and size of each of these pagers, the printed circuit board for each pager was manufactured with a different shape.
  • a credit card pager could use a flat rectangular printed circuit board; however, a pen shaped pager may require a narrower but longer printed circuit board. Therefore, even though the printed circuit boards for each of these shapes may have identical electronic circuitry, each printed circuit board would have to be manufactured differently.
  • Another object of the present invention is to provide an improved printed circuit board. Another object of the present invention is to provide a printed circuit board whose shape may be selected after manufacture in order to be placed within a variety of shaped electronic system housings.
  • a selective call receiver selectively housed within one of two or more housings, wherein each of the two or more housings have one of a plurality of shapes.
  • a printed circuit material is capable of assuming at least two of the plurality of shapes corresponding to the shape of the two or more housings. The printed circuit material is engageably positioned within the housing and is coupled to a battery, antenna, and to an alert device that may be attached to the housing
  • FIGS.1 A and B are side and top views, respectively, of one type of a pager.
  • FIGS.2 A and B are side and top views, respectively, of a second type of a pager.
  • FIGS. 3 A and B are side and top views, respectively, of a third type of a pager.
  • FIGS.4 A and B are side and top views, respectively, of a fourth type of a pager.
  • FIGS.5 A and B are side and top views, respectively, of a fifth type of a pager.
  • FIG.6 is a block diagram of the components of a typical pager.
  • FIG. 7 is a perspective view of a first embodiment of the present invention.
  • FIG. 8 is a perspective view of the first embodiment folded so as to fit within the pager of FIG. 4.
  • FIG. 9 is a perspective view of the first embodiment folded so as to fit within the pager of FIGS. 1 or 2.
  • FIG. 10 is a perspective view of the first embodiment folded so as to fit within the pager of FIG. 5.
  • FIG. 11 is a perspective view of a second embodiment of the present invention.
  • FIG.12 is a perspective view of the second embodiment folded so as to fit within the pager of FIG. 5.
  • FIGs. 1A and IB through 5 A and 5B side and top views of a variety of selective call radio receivers, such as pagers, are illustrated.
  • Each pager comprises a housing 20; switches 21 for controlling power, type of alert, volume of alert, etc.; and ports 22 for emitting an audible alert or audible message.
  • the pagers shown in FIGs. 1, 2, and 4 further comprise a clip 23 for attaching the pager to an item of clothing such as a belt or a shirt pocket.
  • the housing 20 of the pagers shown in FIGs. 1-5 each have a different shape or form factor for satisfying a particular user desire.
  • the pager shown in FIG. 1 is in the shape of a rectangular box for attachment to a belt, for example.
  • the pager shown in FIG. 2 is in the shape of an elongated rectangular box for attachment to the inside of a shirt pocket (pen shape).
  • the pager shown in FIG. 3 is in the shape of an credit card for placement within a pocket, billfold, or purse, for example.
  • the pager shown in FIG. 4 is in the shape of a triangular box for attachment to a belt, or example.
  • the pager shown in FIG. 5 is in the shape of an square box for placement on a desk, for example. Because of the different shapes of these pagers, internal components such as antennas, batteries, and printed circuit boards have different size and location requirements. For example, while a AAA battery may fit within the housing 20 of the belt pager of FIG.
  • a block diagram of a typical pager comprises a printed circuit board 30 including a decoder section, a channel RF section, and an IF section.
  • An antenna 31, a battery 32, an alert apparatus 33, and a control apparatus 34 such as on /off and volume control switches are electrically coupled to the circuit board for performing the pager operation well known to those skilled in the art.
  • a display apparatus 35 may be included in the pager for visually displaying an alert or a message.
  • a printed circuit board 40 may comprise a rigid material (the rigid printed circuit board being well known in the art) or a flexible material such as kapton, and has fold regions 41 wherein the printed circuit board 40 may be folded to assume different shapes (form factors).
  • Electronic devices 42 such as integrated circuits (chips), transistors, resistors, capacitors, and the like are placed on the printed circuit board 40 and electrically coupled for forming a circuit as disclosed in the above referenced patents.
  • the printed circuit board 40 may be cut along regions 41 while maintaining electrical contact via flexible or non-flexible connectors.
  • the shape illustrated in FIG. 8 will readily fit within the -housing 20 of FIG. 4 and the shape illustrated in FIG. 9 will readily fit within the housing of FIGs. 1 and 2.
  • the printed circuit board may be further folded along a second fold region 41 to provide the shape illustrated in FIG. 10 for inclusion in the housing 20 of FIG. 5.
  • the same printed circuit board may be also partially folded along the first fold region 41 to provide the shape illustrated in FIG. 8 for inclusion in the housing 20 of FIG. 4.
  • Functions external to the printed circuit board such as the alert apparatus 33, antenna 31, display 35, battery 32 and control apparatus 34 typically are positioned on the housing in accordance with the shape of the housing.
  • the printed circuit board 30 may be designed and /or the location of the external functions may be modified slightly so the connectors for each external function on the printed circuit board 30 matches the location of each external function.
  • a flexible connector of a given length may be utilized to interconnect the printed circuit board with each external function for each shape of pager.
  • FIGs. 11 and 12 A second embodiment is shown in FIGs. 11 and 12 wherein the portions 43, 44, 45, and 46 are spaced apart but electrically and physically coupled by flexible flanges 47 comprising a flexible material such as kapton.
  • the portions 43, 44, 45, and 46 may be folded once, or twice as shown in FIG. 12, for inclusion in differently shaped housing in a similar manner as discussed above.
