Abstract
Disclosed is an analyzer for producing a digital display of the rate of deviation of a solid state wristwatch from a predetermined norm. It comprises a counter and calculator into which are gated a series of high frequency pulses for a period of time dependent upon the operating frequency of the wristwatch time base under test. Included is a keyboard connected by a manual switch to the calculator so that the device may be operated in a calculator mode as well as a clock circuit by means of which the digital display may be used to indicate time.
Claims17
A timing rate tester for wristwatches having an electrical time standard, comprising:
- an electro-optical digital display;
- a calculator circuit coupled to said display;
- a wristwatch support including an antenna for sensing electrical energy from the time standard of an operating wristwatch mounted on said support;
- a high frequency oscillator for producing a series of high frequency pulses;
- a divider coupled to said antenna for producing a series of low frequency pulses;
- a gate circuit coupled to said divider and said high frequency oscillator whereby the pulses from said oscillator are gated by the output of said divider;
- a counter coupled to the output of said gate;
- sequence control means coupled to the output of said divider;
- keyboard simulator means coupled to the outputs of said sequence control means and said counter for transmitting data from said counter to said calculator circuit under the control of said sequence control means and for controlling said calculator circuit to operate on the data transmitted from said counter in a pre-determined manner;
- a keyboard;
- and a manually operated mode switch coupled to said calculator circuit for alternatively coupling said keyboard simulator and said keyboard to said display.
A timing rate tester according to claim 5 wherein said diodes comprise a seven bar segment array;
- a plurality of segment drivers coupling said calculator circuit to one side of said diodes and a plurality of digit drivers coupling said calculator circuit to the other side of said diodes.
