Abstract
An improvement over the device disclosed in U.S. Pat. No. 3,634,885 consisting of the incorporation into the control circuitry of time delay means serving to delay activation of the message playback means for a predetermined time after the attitude switch has become closed due to collapse or seizure of the wearer of the device. Included in the improved control system is a manually operable switch permitting the wearer or user of the device to bypass the delay circuit and thereby instantly activate the device in the event that he senses that a blackout or loss of ability to personally communicate is imminent.

FIG. 1 is a block-schematic showing of a preferred embodiment of the improvement of the invention.
FIG. 2 is a circuit diagram of the invention.
The disclosure set forth in US. Pat. No. 3,634,885 is hereby incorported herein by reference. In FIG. 1, components corresponding to those of the drawings of US. Pat. No. 3,634,885 are identified by the same reference numbers. A comparison of present FIG. 1 with FIG. 4 of US. Pat No. 3,634,885 will indicate that the former differs from the latter in embodying (l) delay means 60 and clock and latch logic means 62 between the attitude switch 34 and the latching relay or power switch 32 and (2) a manual switch 64 whereby the attitude sensing, the delay and the clock and latching circuitry may be bypassed when the wearer or user of the device senses an imminent state of seizure or blackout.
The delay means 60 includes a timing capacitor 66 adapted to be charged and provide an output signal to.
the clock and latch logic means 62 a predetermined time, say seconds, after the closing of the attitude or mercury switch 34. Thereafter the nand'gates 68 of the clock and latch logic means 62 serve to cause the closing of the latching relay or power switch 32 and thereby actuate the motor drive 40 and the annunclator of the warning message.
As previously, the on-off switch 18 is preset to the closed position. Closing of switch 64, as previously stated, then connects the battery 28 directly with the drive motor 40.
Other trip logic means may be readily employed. For instance, the time delay and power switch tripping circuit may comprise a resistance capacitance set, for example, at 20 seconds, clock means to measure the length of the pulse, pulse-length responsive means operable upon the occurrence of a flip-flop going high to turn on the power transitor and enable the driving of a load of 7 8 or 9 volts at 150 ma. Such circuitry may be incorporated into the logic system to enable the connection of power to standby logic for as long as the shelf life of the battery, i.e., without measurable current drain.
The trip logic system, i.e., the built-in predetermined time delay system between the closing of the attitude switch and the actuation of the annunciator, serves to prevent actuation of the annunciator due to mere splash-bridging of the contacts of the exemplary mercury type attitude switch and serves to prevent such actuation when, for example, the wearer slides headlong into third base unless of course he fails to arise within the programmed allotted time.
What is claimed is:
1. A warning device to be attached to a person prone to incapacitating medical conditions or prostrating seizures comprising a warning signal annunciator which when activated repeatedly emits a recorded verbal message to inform bystanders of the nature of such persons condition or seizure and how he is to be treated prior to the arrival of medical aid, a power supply for the annunciator, and control means to connect the power supply with the annunciator, said control means comprising sensing means operable to sense the existence of a supine or non-erect position of the wearer of the device and to transmit a signal only during the time the wearer is in such position, a switch operable upon closure to connect the power supply to the annunclator despite a subsequent change in the wearers position from supine to a normal one, and time delay means to receive said signal and in response to the receipt of said signal for a predetermined period of time to close said switch.
2. The combination of claim 1 including a manual switch connected in parallel to said first-mentioned switch and operable upon being closed to connect the power supply to the annunciator in bypassed relation to said control means.
3.
