| 073100420 | Timing apparatus (e.g., fuse, camera, or shutter) | 6 |
| 20120111089 | Method for Synchronising Measurements - A method for synchronizing the measurements obtained, over a given period, from a number of measurement acquisition means for acquiring measurements of characteristics associated with the stresses withstood by a tire fitted on a running vehicle. The measurement acquisition means are brought into operation independently of one another and at least one indexing at a given instant of the measurements from each of said means is created relative to a time-measuring reference means. | 05-10-2012 |
| 20140338420 | Method of Determining a Calibration or Maintenance Time Interval - A method of determining a calibration or maintenance time interval, comprising the steps of: determining a criticality of the specific device, based on the criticality setting a reliability target for the device, wherein the reliability target denominates the probability of the device to be compliant according to a predefined criterion at the end of the calibration or maintenance time interval; defining compliancy ranges for a measurable degree of compliance of the device; selecting a reliability model for a reliability of the device as a function of a normalized time interval and a set of at least one parameter from a variety of predefined reliability models, determining a separate set of parameters for the selected reliability model for each of the compliancy ranges based on prescribed reliability expectation values for each of the error ranges, which a reliability function associated with this error range shall comply to at at least one predefined normalized time, determining the degree of compliance of the specific measurement device and based on the degree of compliance determining the corresponding compliancy range; determining a normalized calibration or maintenance time as the time, at which a reliability function given by the selected reliability model and the set of parameters determined for this compliancy range equals the reliability target; and determining the next calibration or maintenance time interval based on a product of this normalized calibration or maintenance time and a given reference time interval. | 11-20-2014 |
| 20160161919 | TIME INDICATING DEVICES BASED ON COUNTERBALANCING REACTIONS - Indicating devices based on the counter balancing effect of one parameter with that of others are disclosed. Color changing and self-reading indicating devices, such as a time indicator having essentially no effect of temperature are developed by this method. In diffusion based time-temperature indicating devices, the effect of temperature is lowered by crosslinking the medium of the device. The devices have net activation energy near zero kcal/mole. | 06-09-2016 |
| 073100430 | Chronometer (e.g., clock, watch, or watch unbalance) | 3 |
| 20140250972 | Quality of Precision Time Sources - Systems and methods for detecting the failure of a precision time source using an independent time source are disclosed. Additionally, detecting the failure of a GNSS based precision time source based on a calculated location of a GNSS receiver is disclosed. Moreover, the system may be further configured to distribute a time derived from the precision time source as a precision time reference to time dependent devices. In the event of a failure of the precision time source, the system may be configured to distribute a time derived from a second precision time source as the precision time signal during a holdover period. | 09-11-2014 |
| 073100450 | Using optical sensor or element | 2 |
| 20160070236 | DEVICE FOR MEASURING THE ACCURACY OF A MECHANICAL WATCH - A device for measuring the accuracy of a mechanical watch includes a time reference source, a calculating mechanism, and another data processing unit. The time reference source is formed by an internal time reference source, or by a receiving and processing mechanism arranged to receive and process signals transmitted by an external time source to permanently update a repeater clock internal to the device. The calculating mechanism is arranged to calculate time differences between display values, and/or between time reference points provided by the time reference source, and to calculate a variation in rate. The another data processing unit is arranged to store and process at least one variation in rate calculated by the calculating mechanism, and/or a viewing mechanism arranged to display at least one variation in rate calculated by the calculating mechanism. | 03-10-2016 |
