Abstract
In order to ensure that a user of a battery powered receiving apparatus is available to be called during at least one duty period during every 24 hours and to extend the battery life by avoiding the inadvertent energisation of the receiving apparatus outside the duty period, the receiving apparatus is provided with programmable means for causing a receiver portion (12) of the apparatus to be energised for one duty period in every 24 hours. The programmable means in one embodiment comprises two 24-hour timers (20,22), one for the ON time and one for the OFF time, which are connected to a clock generator (18). <IMAGE>
Description
SPECIFICATION
Battery powered receiving apparatus
The present invention relates to battery powered receiving apparatus, particularly radio receiver apparatus such as paging receivers, which are on standby for considerable periods of time.
When such radio receiver apparatus are on standby, parts of the receiver apparatus are switched off in order to economise on battery power and thereby extend the life of the battery or batteries, those parts being energised on the receipt of a coded signal. In order to save additional battery power,-these receiver apparatus are equipped with manually operable on/off switches to turn the receiver apparatus off at the end of a duty period of the user and turn-on at the commencement of a new duty period. A problem which occurs frequently is that the user of the receiver apparatus forgets to actuate the on/off switch at the end of a duty period or at the commencement of a new duty period. In the former case battery power is needlessly wasted and in the latter case the user cannot be contacted.
Domestic radio receivers including an alarm clock are well known and for convenience of description will be referred to as "clock radios". Clock radios can be preset so that the radio section is energised at a predetermined time for the purpose of waking-up the user. As clock radios are normally powered from the main electricity supply and consume a small quantity of power then the matter of battery economy does not arise. Thus it is not critical from the power consumption point of view how long a clock radio remains energised once turned-on. Furthermore, a clock radio has to be set manually each time by a user otherwise it will not be switched-on at the desired time.
An object of the present invention is to overcome these drawbacks by relieving a user of a battery powered receiving apparatus of the need to rememberto switch-on and -off the apparatus.
According to the present invention there is provided a battery powered receiving apparatus comprising a receiving portion, switching means for enabling the receiving portion to be energised and de-energised, and programmable timing means for operating the switching means at predetermined times, whereby the energisation and de-energisation of the receiving portion is controlled automatically.
By being able to switch-on and -off the receiving portion of the receiving apparatus at the beginning and end of a duty period one can ensure that a user is available for alerting as desired and also the most economical use is made of the batteries in the apparatus.
The battery powered receiving apparatus made in accordance with the present invention may include means for reprogramming the times set in the programmable timing means.
In one embodiment of the receiving apparatus made in accordance with the present invention the programmable timing means comprises two 24hour timers, one of the two timers being for the ON time and the other of the two timers being for the
OFF time, and a clock generator coupled to the timers.
The receiving apparatus may further comprise
means for indicating the energisation/deenergisation status of the receiving portion. Addi tionallyfurther means may be provided whereby the energisation and de-energisation status of thereby ceiving portion can be overridden without causing the predetermined times set in the programmable means to be reset.
In another embodiment of the receiving apparatus made in accordance with the present invention the programmable timing means comprises a presettable ON-timer register, a presettable OFF-time register, and means for comparing a count incremented in a counter with one or the other of the ON time register and the OFF time register.
The apparatus may further comprise display means for displaying the ON and/or OFF times at least when one or both is or are being reprogrammed.
The present invention will now be described, by way of example, with reference to the accompanying drawings, wherein:
Figure 1 is a block schematic circuit diagram of those parts of one embodiment of a paging receiver which are necessary for the understanding of the present invention,
Figure 2 is a block schematic circuit diagram of a modified embodiment to that shown in Figure 1, and
Figure 3 is a block schematic circuit diagram of those parts of another embodiment of a paging receiver which are necessary for the understanding of the present invention.
Referring to Figure 1, the paging receiver 10 comprises a main receiver portion 12 which includes a decoder and output stages of any suitable design.
The receiver portion 12 is energised from a battery power source of +V volts via a PNP switching transistor 14. The base bias of the transistor 14 is controlled buy a programmable timing circuit 16 which may be part of the decoding circuit.
The programmable timing circuit 16 comprises a precision clock generator 18 which is coupled to a 24-hour ON timer 20 and to a 24-hour OFF timer 22.
The ON timer 20 is coupled to one input of a two-input OR gate 26. An ON switch 28 is connected to the second input of the OR gate 26 whose output is connected to a reset input R of set/reset flip-flop 30. An OFF switch 32 and an output of the OFF-timer 22 are connected to respective inputs of a two-input
OR gate 34 whose output is coupled to a set input S of the flip-flop 30. A Q output of the flip-flop 30 is coupled to an "ON" display device 36, to an edge triggered reset input R of the ON timer 20, and to the base electrode of the transistor 14. The display device 36 may comprise a liquid crystal display device. A Q output of the flip-flop 30 is connected to an edge triggered reset input R of the OFF timer 22.
In operation the clock generator 18 supplies clock pulses to both the timers 20 and 22 at a given fixed frequency. The timers 20 and 22 are reset to zero by actuation of the respective switches 28,32. When the timer 20 is full after 24 hours from its time of reset it produces an output which resets the flip-flop 30 causing the 0 output to go low. The low Q output causes the transistor 14to be biased on and in so doing the receiver portion 12 is energised such that normal pager operation may occur including integral main-standby switching. Additionally the ON timer 20 is reset as a negative edge triggered function and the display device 36 indicates that the receiver portion 12 is energised.
Subsequently when the OFF timer 22 is full then its output sets the flip-flop 30 so that its Q output goes low causing the OFF timer 22 to be reset as a negative edge triggered function and its 0 output goes high. This high output renders the transistor 14 non-conductive thereby de-energising the receiver portion 12 and simultaneously causes the ON display device 36 to be extinguished.
Once the ON and OFF timers 20, 22 have been set-up using the switches 28 and 32, respectively, then an output is produced by each timer 20,22 every 24 hours. Thus if a user of the paging receiver 10 is on duty between 08.00 hours and 19.00 hours then at 08.00 hours on the first day he actuates the
ON-switch 28 which causes the flip-flop 30 to be reset and the Q output to go low. Thus the ON-timer 20 is reset by negative edge triggered action and at 08.00 hours each day it will produce an output which is used to turn-on the receiver portion 12. At 19.00 hours on the first day the user actuates the OFFswitch 32 which causes the flip-flop 30 to be set and the OFF timer 22 to be reset by negative edga triggered action. Consequently at 19.00 hours each day the OFF-timer 22 produces an output which is used to turn-off the receiver portion 12.
If the duty period should change to say 07.00 hours to 18.00 hours then at 07.00 hours on the first day, when the receiving portion 12 is de-energised, it will be necessary to actuate the ON switch 28 to energisethe receiving portion and to reset the timer 20 and at 18.00 hours to actuate the OFF switch 32 to de-energise the receiving portion and to reset the timer 22. Thereafter the receiving portion 12 will be energised between 07.00 hours and 18.00 hours.
In the cases where the ON-time is to be changed and the receiving portion 12 is energised and/or the
OFF-time is to be changed and the receiving portion
12 is de-energised, then actuating the switches 28 and 32 at the desired times will cause their respective timers 20, 22 to be reset and to start counting again. If desired a delay of say 2 seconds may be
introduced in the resetting of the timers 20, 22 to avoid unintentionally resetting the timers 20, 22 by the switches 28,32 being actuated inadvertently.
The embodiment shown in Figure 2 differs from that shown in Figure 1 in that the ON display device 36 is omitted.
An indication of the status "ON" or "OFF" of the
paging receiver 10 can be given audibly by means of tones of different patterns.
In order to do this, a "bleep" generator 96 and
associated transducer 98 is coupled to the switches
28,32 as shown. A further connection is made to the
"bleep" generator from the Q output of the flip-flop
30. Between the switches 28,32 and the OR gates 26,
34 are connected 2 second delay circuits 100, 102
which are connected to two input AND gates 104, 106, the second input of each gate 104,106 is connected directly to the switches 28,32 respectively. The outputs oftheAND gates 104, 106 are connected respectively to the OR gates 26,34.
Additionally delay circuits 110 and 112 which have a delay time of 4 seconds are connected to the switches 28 and 32 respectively. The delay circuits 110 and 112 are connected to one input of two-input
AND gates 113, 115 whose second input is connected to the switches 28,32 respectively. The outputs of the gates 113, 115 are connected respectively to one input of AND gates 114,116 whose second inputs are connected resepctivelyto the 0 and 0 outputs of the flip-flop 30. The outputs of the
AND gates 114, 116 are connected to the negative edge triggered reset inputs of the timers 20, 22, respectively.
The basic automatic switch-ON and switch-OFF operations are as described with reference to Figure 1. However if it is desired to check if the paging receiver 10 is energised or not, one merely depresses the ON or the OFF switch 28 or 32 for less than 2 seconds. The energisation status of the paging receiver is given by the Q output of the flip-flop 30 so that the transducer emits an audible signal of an appropriate tone pattern irrespective of whichever switch is depresses, for example a single short tone for "ON" and two short tones for "OFF".
If the switch 28 or 32 is depressed for between 2 and 4 seconds, the status of the pager energisation is changed without affecting the timers 20,22. In other words, the status of the pager is overridden without affecting the times automatically preprogrammed into the timers 20, 22. As an example if the automatic turn-on and turn-off times are 09.00 hours and 18.00 hours and the user wants to be available for alerting between 18.01 and 21.30 hours, then at 18.01 hours the ON switch 28 is actuated for between 2 and 4 seconds so that the pager receiver is energised.
Then at 21.30 hours the "OFF" switch 32 is actuated for between 2 and 4 seconds and the pager receiver 10 is de-energised. At 09.00 hours on the following day, the receiving portion 12 is turned-on automatically and at 18.00 hours the receiving portion is turned off automatically as programmed.
If it is desired to reset one or both of the timers 20, 22, the appropriate switch 28 or 32 is depressed for geater than 4 seconds to overcome the delays incurred by the delay elements 110 or 112 and cause the appropriate timer 20 or 22 to be reset at the desired time.
The embodiment of the paging receiver 10 shown in Figure 3 takes advantage of the fact that the
receiver already includes a micro-computer timing control 40 for turning on the receiving portion 12 at those instances, for example when a synchronisation code word and when an address code word are
expected. A display device 42 capable of indicating
in hours and minutes is coupled to the timing control 40, the counter 44 is incremented by a clock
generator (not shown) in the timing control 40 and
serves to store the absolute time in hours and
minutes. The initial setting of the counter 44 is done
by actuating a mode selector 46 which couples the
display 42 to the counter 44 by means of a switch 48, the hours are set-up in the counter 44 and by means
of a switch 50 the minutes are set-up in the counter 44.
In order to set the switch-ON time, an ON register
52 is connected to the timing control 40 and by
means of actuating the mode selector 46 the display 42 is coupled to the ON register 52. The ON time can
be set in the register 52 by suitable actuation of the switches 48,50. The OFF time can be set in an OFF
register 54 by connecting it to the display 42 and
actuating the switches 48, 50.
In operation when the count in the counter 44 corresponds to that in the register 52, the transistor
14 is rendered conductive and the receiving portion
12 is energised. Similarly when the count in the counter 44 corresponds to that in the register 54 then the transistor 14 is rendered non-conductive and the
receiving portion 12 is de-energised.
Compared with the embodiments shown in Figures 1 and 2, that of Figure 3 is easier to set up and depending on the construction of the timing control 40 it may be possible with additional registers to set-up two or more periods in every 24 hours when the receiving portion 12 should be energised. In practice the counter 44, the registers 52, 54 and any additional registers will be incorporated into the timing control 40. If desired the timing control 40 may contain a calender which enables the automatic -ON and -OFF facility to be inhibited for example at weekends.
