Abstract: A time-division multiplexed paging system for transmitting multiple paging messages on the same frequency. A geographic area is divided into a plurality of cells having base stations that transmit radio frequency signals in the cells. Each base station is assigned a time slot at which paging messages may be transmitted. The assignment is made such that no base stations having overlapping radio frequency coverage areas transmit during the same time. A locate signal is simultaneously broadcast throughout a geographic area in order to locate a paging unit. Upon receipt of the locate signal, the paging unit transmits an acknowledge signal back to the paging system. The cell in which the paging unit is located is determined based upon the signal strength of the received acknowledged signal. A paging message is transmitted from the base station in the cell in which the paging unit is located during the time slot that is assigned to the base station.

Abstract: A method and apparatus for applying flux to a series of metallization contacts or plated contact pad a substrate exposed by an apertured solder mask, employs a compressible transfer pad. A central flux pick-up area is formed on the transfer pad bottom surface. The bottom surface may be spherical and may include a cylindrical post onto which a predetermined amount of flux is transferred, such as by dipping the pick-up area into a reservoir of semi-liquid paste flux. The transfer pad is then positioned over and compressed on the solder mask such that the picked up flux on the flux pick-up area of the transfer pad is pressure forced by compression of the transfer pad through apertures in the solder mask directly and successively into all the series of depressions formed on the substrate until all the depressions are substantially filled with flux.

Abstract: An integrated circuit package, and a method for forming the integrated circuit package, including a single layer or multilayer substrate in which interconnection vias are formed is described. Laser energy is swept across a surface of a mask in which holes have been formed. Laser energy passing through the holes of the mask forms vias in a substrate held in place below the mask. The laser energy is swept at such a speed and is maintained at such an energy level that the laser energy forms vias in the substrate, but does not penetrate a set of leads attached to the substrate. Vias may be formed in this way by either a mask imaging, contact mask or conformal mask technique. The laser energy is emitted from a non-thermal (e.g., excimer) laser. The substrate is formed of an organic (e.g., epoxy) resin. The resin may include reinforcing fibers (e.g., aramid fibers). Substrates may be formed on one or both sides of the set of leads.

Abstract: A clock synchronization system for synchronizing a number of paging stations (24) with a system controller (23). Each paging station has a clock that includes a counter (52) that indicates the current local time and which is sequentially incremented by a counter advance signal applied thereto. A voltage controlled oscillator (58) generates the clocking signal that controls the advancement of the counter. A CPU (50) in the system controller monitors the time indicated by the counter and compares it to timing information received from a system clock. The timing information includes a time mark and a time mark send time. The system clock transmits to each paging system the time mark. At a future time, the system clock transmits the time mark send time which is the precise time at which the time mark was transmitted. The paging stations each measure the time interval between the time at which the time mark arrived and the time at which the time mark was transmitted by the system clock period.
