Definitions

  • This invention relates generally to the area of portable receivers with time of day clocks .
  • this invention relates to a portable receiver receiving a signal indicating a location, the portable receiver determining a time zone corresponding the the location and adjusting the time of day clock in response thereof.
  • Prior art paging systems which transmit time of day information suffer from several problems.
  • a person cannot choose to operate their clock several minutes fast as many people desire.
  • the time signal must be transmitted in every location that the business person travels. This can be a difficult requirement to impose on nation wide systems operating in conjunction with independently operated local paging systems.
  • a portable receiver comprises a receiving means receiving a location signal, the location signal being indicative of a location, a time keeping means for keeping time of day, and an adjusting means responsive to the location signal for adjusting said time keeping means.
  • Figure 1 shows a block diagram of a paging receiver which operates in accordance with the present invention.
  • Figure 2 shows a flowchart of the adjustment of a time of day clock in accordance with the present invention.
  • Figure 3 shows an example of a display on a paging receiver operating in accordance with the present invention.
  • FIG. 1 shows a block diagram of a paging receiver 20 which operates in accordance with the present invention.
  • the paging receiver receives a signal having a location signal included therein.
  • the location signal includes the location of the city or locality in which the paging receiver is operating.
  • An enabling description of such a pager is included within U.S. Patent No. 4,644,347 to Lucas et al. which is hereby incorporated by reference.
  • the paging receiver additionally has a time of day clock, and an enabling description of a paging receiver having a time of day clock is included in allowed U.S. Patent Application No. 07/141,458 to DeLuca et al., which is also hereby incorporated by reference.
  • the paging signal is collected by antenna 22 and demodulated by receiver 24.
  • the demodulated paging signal is processed by an address decoding means 26 which searches for an address signal matching a predetermined address signal assigned to the pager.
  • message decoding means 28 decodes information associated with the address.
  • the address and information comprise a message which may be displayed on a display means 30 in a known manner.
  • the demodulated information is also processed by a means for detecting the location signal 32.
  • the location signal identifying a city or locality may be included within a unique preamble signal, a unique start code (SC) , or location of a unique binary word appended within the preamble signal.
  • the local area decoder 32 and the receiver 24 operate as a receiving means receiving for a location signal.
  • The'location signal may be made available to a frequency adjusting means 33 which adjusts the receive frequency of receiver 24 to correspond to the proper local frequency, as described in the aforementioned Lucas et al. patent.
  • the location signal is also made available to time zone adjusting means 34 which adjusts the time of day clock 36 in response to the location signal and on the basis of information included within a memory means 38.
  • address decoder 26, message decoder 28, local area decoder 32, adjusting means 34, time keeping means 36 and memory means 38 may be implemented within a host microcomputer.
  • a preferred host microcomputer for the present invention is the Motorola
  • FIG. 2 shows a flowchart of the adjustment of a time of day clock in accordance with ' the present invention.
  • step 50 checks if a location signal has been received by local area detector 32. If received, step 55 performs a series of operations in order to adjust the time of day clock 36. First, the local time zone value is set to be equal to the time zone corresponding to the location signal just received. Then the clock time zone is set to be equal to the time zone corresponding to the time zone of the time of day clock. A new time is calculated by adding the clock time and the clock time zone while subtracting the local time zone.
  • Table 60 shows a table of location signals and time zones which are stored in memory means 38.
  • FIG. 1 shows an example of a display on a paging receiver operating in accordance with the present invention.
  • the display 70 includes date information 72 which is shown to be "April 24", time of day information 74 which is shown to be "10:10 AM”, and time zone information 76 which is shown to be "EST" representing Eastern Standard Time. Additionally, numeric message information display 78 is provided for displaying messages received by the pager.
  • information display could additionally display alpha or graphic information, and that the information of 72, 74, and 76 could be displayed on 78 in the absence of message information thereby providing for the elimination of display segments dedicated to the functions of 72, 74 and 76, and thus providing for a smaller display.
  • One example of the operation of the present invention is a traveling business person traveling from Washington, D.C. to Los Angles. While in Washington ,D.C, the pager received a location signal indicating that Washington, D.C. was the location of the paging receiver, in response to which the pager displays the local time, date and "EST" indicating Eastern Standard Time. Upon arrival at Los Angles the pager receives a new location signal indicating that Los Angles is the location of the paging receiver.
  • time zones such as Caracas which according to table 60 cause the minutes to be adjusted, were eliminated, only the hours of the time of day clock need to be adjusted, thereby reducing the complexity of the adjusting means.
  • the advantage of using the location signal to set the time zone is that the location signal is already being transmitted and used for nation wide pagers in order that they may select a local channel, as described in Lucas et al. No additional time of day signal needs to be transmitted in order to adjust for travel between time zones. This resolves a number of queueing issues involved with paging transmitter systems as well as eliminating the air time required to transmit time of day signals. This additionally allows the time of day clock to be set to operate ahead of (or behind) the true time of day in a first location and preserving the setting as the as time zones are traversed. It is obvious that numerous additional modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practised otherwise than as specifically described herein.

Abstract

Un récepteur portatif (20) comporte une horloge (36), et reçoit un signal indiquant l'emplacement du récepteur portatif. Ledit récepteur portatif comporte une mémoire (38) comprenant une pluralité d'emplacements auxquels correspondent des fuseaux horaires. Lors de la réception du signal d'emplacement, ledit récepteur détermine le fuseau horaire de l'emplacement ainsi que le fuseau horaire de l'horloge. Ladite horloge est ensuite réglée afin de correspondre au fuseau horaire de l'emplacement. On peut également utiliser le signal d'emplacement pour régler la fréquence de fonctionnement dudit récepteur.
