  • Patent number: 7937232
    Abstract: Embodiments of the present invention relate to managing timestamps associated with received data. According to one embodiment, data is collected from a device that generates data at a specified rate, but which lacks a built-in clock. An accurate timestamp is assigned to the data by first taking an absolute timestamp from a reference clock, and then adding a calculated amount of time to each subsequent data point based on an estimate of the sampling frequency of the device. As the generated timestamp drifts from the actual reference clock time, the sampling frequency is re-estimated based on the amount of detected drift.

The circuit has a plurality of substantially identical pulse shaper elements, each of which expand the pulse of an input signal whose duty cycle is to be measured by a same amount. The outputs of the pulse shaper elements may be coupled to substantially identical divider circuits whose outputs are coupled to a multiplexer that selects two inputs for output to a set of master/slave configured flip-flops, one input serving as a clock and the other as data to the flip-flops. The flip-flops sample the divider outputs selected by the multiplexer to detect if the dividers have failed or not. The outputs of the flip-flops are provided to an XOR gate which outputs a duty cycle signal indicative of the duty cycle of the input signal.

    Abstract: A method and an apparatus for calculating the separation time of the arcing contacts of a high-voltage switchgear which is operatively coupled to a synchronous switching device and to an auxiliary switch having auxiliary contacts operatively connected to the arcing contacts. During execution of a predefined test condition the separation time of the arcing contacts and of the auxiliary contacts is measured. The time delay between the measured separation time of the arcing contacts and of the auxiliary contacts is calculated. Upon separation of the arcing contacts under an operating condition other than the predefined test condition, the separation time of the auxiliary contacts is measured. Then, the separation time of the arcing contacts is calculated as the difference between the separation time of the auxiliary contacts measured during the operating condition other than the predefined test condition and the calculated time delay.

  • Patent number: 7865331
    Abstract: Time synchronization of two clocks is disclosed herein, such as two stationary clocks. A global time signal from a global time reference or common time source can be used to calculate a common view based clock offset between the two clocks. In parallel, a network based clock offset between the two clocks can be calculated based on messages exchanged over a communication network interconnecting the two clocks, without reverting to the global time reference. Two recent values (e.g., the two most recent values) of the common view clock offset and the network based clock offset can be combined or superposed in a seamless way to produce a final time offset estimate. The combination of independently calculated common view and network based clock offsets can be a weighted average of the two values, involving respective weights based on quality estimates of the latter.

    Abstract: A process for correcting the time stamp of recordings such as photographs, obtained in many locations. An onboard clock records a time stamp for each photograph. GPS tracking data is obtained during movement of the camera. A time correction is sought, to account for an unknown error in the onboard clock, relative to the trusted GPS time data. To this end, an assigned location of each photograph is generated from the location tracking data and from an estimated time correction. Indicators of an appropriate time correction include clustering of the assigned locations, and correlation of the assigned locations to locations of reduced velocity. A GUI can be used to enable user assessment of clustering and/or correlation, and indication of a suitable time correction. Or, algorithmic assessment can be used.

  • Patent number: 7774428
    Abstract: A mechanism is provided for automatic response time measurement of Lightweight Directory Access Protocol (LDAP) server operations are provided. The mechanism makes use of an LDAP server plug-in interface and LDAP server plug-in modules to automatically inject response time measurement code before and after each LDAP server operation during real time operation of the LDAP server in a runtime environment. In addition, the mechanism makes use of correlation tokens in the LDAP environment so that LDAP client and server operations may be correlated with one another in an end-to-end transaction. Mechanisms for passing correlation tokens between plug-in modules for the same LDAP server operation and passing correlation tokens between the LDAP client and LDAP server, and among LDAP client calls within a single session, are also provided.

  • Patent number: 7756659
    Abstract: In an integrated circuit with at least two separate timing circuits, for example both a serializer and a deserializer, a trim value correction factor is developed and applied at the testing of the chip. The correction trim value brings the VCO frequency of the serializer into specifications, but the trim value may also be used to alter the delay between a received clock and data in the deserializer. Since both the serializer and the deserializer were made with the same process, the received clock delay may be corrected by substantially the same correction factor as that applied to the VCO. Illustratively the trim values may be stored on the IC.

  • Publication number: 20100138187
    Abstract: Time synchronization of two clocks is disclosed herein, such as two stationary clocks. A global time signal from a global time reference or common time source can be used to calculate a common view based clock offset between the two clocks. In parallel, a network based clock offset between the two clocks can be calculated based on messages exchanged over a communication network interconnecting the two clocks, without reverting to the global time reference. Two recent values (e.g., the two most recent values) of the common view clock offset and the network based clock offset can be combined or superposed in a seamless way to produce a final time offset estimate. The combination of independently calculated common view and network based clock offsets can be a weighted average of the two values, involving respective weights based on quality estimates of the latter.

  • Patent number: 7706996
    Abstract: Circuits, methods and apparatus are provided to reduce skew among signals being provided or transmitted by a data interface. Signal path delays are varied such that signals transmitted by a memory interface are calibrated or aligned with each other along a rising and/or falling edge. For example, self-calibration, external circuitry, or design tools can provide skew adjustment of each output channel by determining one or more delays for each output channel path. When aligning multiple edges, the edges of the output signals may be aligned independently, e.g., using edge specific delay elements.

  • Patent number: 7675822
    Abstract: A clock device is held by a moving body, and receives a modulated wave from two electromagnetic fields generated by an antenna formed in a predetermined shape and disposed on a path. The clock device demodulates the modulated wave and acquires unique identification information. The clock device determines a non-detection period after the identification information is acquired. The clock device acquires a reference time corresponding to a middle of the non-detection period, and specifies the acquired reference time as a pass time when the moving body has passed through a point where the antenna is disposed.
