Anti-Tamper Digital Clocks - An Overview



Thus, the existing creation just isn't meant to be limited to the embodiments demonstrated herein but should be to be accorded the widest scope according to the rules and novel features disclosed herein.

The water level range can be determined depending on delayed monotone signals from one or more former clock Assess time. The plurality of resettable hold off line segments might comprise faucets along a delay line. Alternatively, the plurality of resettable hold off line segments comprises parallel delay lines.

suggests for delaying the monotone signal to deliver a plurality of delayed monotone indicators having discretely raising hold off instances among a bare minimum hold off time plus a most delay time and every of the plurality of delayed monotone alerts having either a a single or possibly a zero logic price;

The water level quantity could possibly be decided according to delayed monotone signals from one or more former Assess time. The plurality of resettable delay line segments may perhaps comprise faucets alongside a hold off line. Alternatively, the plurality of resettable hold off line segments comprises parallel hold off lines.

means for delaying the monotone sign to create a plurality of delayed monotone alerts having discretely escalating delay moments between a minimum amount hold off time and also a most hold off time and each in the plurality of delayed monotone signals acquiring both a a person or even a zero logic worth;

an evaluate circuit, induced by the clock, that takes advantage of the plurality of delayed monotone indicators to detect a clock fault.

a plurality of resettable delay line segments that delay the monotone signal to produce a respective plurality of delayed monotone signals Just about every obtaining both a a person or maybe a zero logic worth, whereby resettable hold off line segments concerning a resettable hold off line segment related to a bare minimum delay time plus a resettable delay line segment affiliated with a highest delay time are Every related to discretely escalating hold off occasions; and

The system from the creation might detect quicker- and slower-than-envisioned clock frequencies. It also could detect a set up-time violation on the monotone signal to sense quicker than envisioned frequencies or glitches. A substantial modify in the number of set up-time violations may very well be detected to provide an adaptive surroundings insensitive sensor.

In-frame structure permits clock to be accessed for adjustment or battery alter with out more info removing metal housing

The CL100 functions an entry panel (with ligature resistant/tamper resistant barrel lock and circular important) for workers to modify info on the LED Exhibit without the need of removing the duvet/clock in the wall.

In case your Television set established has an additional USB port, it must electric power the supporters and turn them off and on Whilst using the Television; Typically, a USB ability supply could be concerned.

A monotone signal is presented in the course of an Examine period of time. The monotone sign is delayed employing Every single on the plurality of resettable hold off line segments to crank out a respective plurality of delayed monotone signals. A clock is utilized to induce an Appraise circuit that uses the plurality of delayed monotone signals to detect a voltage fault.

Yet another element of the invention may perhaps reside in an equipment for detecting clock tampering, comprising: indicates for supplying a monotone signal throughout a clock Examine time frame related to a clock; usually means for delaying the monotone signal using a plurality of resettable hold off line segments to generate a respective plurality of delayed monotone indicators having discretely growing hold off moments between a least hold off time and also a greatest delay time; and signifies for using the clock to result in an Appraise circuit that utilizes the plurality of delayed monotone alerts to detect a clock fault.
