| 377016000 | Determining machine or apparatus operating time or monitoring machine, apparatus or operation | 7 |
| 20080304613 | MONITORING DEVICE FOR CONNECTORS - An exemplary monitoring device includes: a time chip connected to a connector to generate a time signal and a count signal when the connector is working, the time signal indicating how long the connector is in use, the count signal indicating that the total number of times the connector has been used should be incremented by one; a processor connected to the time chip to receive the time signal and count signal, and generate a data signal including a total service time and a total number of times the connector has been used; a clock generator connected to the processor to provide a clock signal; and an output port connected to the processor to output the data signal. The monitoring device keeps a watch on a connector for showing the service information about the connector to make an operator know if the connector needs to be replaced. | 12-11-2008 |
| 20090274263 | Run-Time Meter With Blind Interface - A run-time meter for monitoring at least the amount of time a piece of equipment has been operating. The run-time meter comprises a counter and a blind interface. The counter is actuated to begin counting when the piece of equipment operates. The counter is adapted to register run-time data including at least the cumulative amount of time the piece of equipment operates. The counter has a memory portion for storing the run-time data and for storing a unique identifier selectively associated with the piece of equipment. The blind interface is in communication with the counter to permit the run-time data to be extracted from the memory portion of the counter by an external reader while preventing a user from perceiving the run-time data via the blind interface. | 11-05-2009 |
| 20110058639 | COUNTING APPARATUS - A counting apparatus includes a sampling circuit, and a counting and displaying circuit. The sampling circuit includes an interface, a first electric switch, and a second electric switch. The counting and displaying circuit includes a counter and a display tube. Seven input terminals of the display tube are connected to seven output terminals of the counter correspondingly. A clock-up counting terminal of the counter is connected to the second terminal of the second electric switch. | 03-10-2011 |
| 20110091005 | METHOD FOR CLOCKING CUMULATIVE OPERATING TIME FOR A CARGO-HANDLING VEHICLE, AND THE CARGO-HANDLING VEHICLE BY USE OF THE METHOD - The use time till a display unit including an hour meter (a time measuring device) is replaced can be continued even if the time measuring device fails, and false alteration after shipping can be prevented while infallibly resetting the hour meter to zero when the vehicle equipped with the hour meter is shipped from the factory. The cargo handling vehicle includes a first storage device for accumulatively storing the vehicle use time measured by a first time measuring device provided in a display unit of the vehicle and a second storage device for accumulatively storing the vehicle use time measured by a second time measuring device provided in a control device. The control device allows the first and second storage devices to communicate the accumulated use times stored therein when the electric power of the vehicle is turned on. The control device compares the accumulated use times and writes the longer accumulated use time in the storage device storing the shorter one. | 04-21-2011 |
| 20120155602 | TEMPORAL BASED MOTION SENSOR REPORTING - Methods and systems may include a motion sensor and logic to sample an output signal of the motion sensor. The logic can also be configured to track an amount of time the motion sensor is triggered based on the output signal, and transmit the amount of time over a wireless link on a periodic basis. | 06-21-2012 |
| 20120250815 | Method for Determining Usage Rate of Breaking Hammer, Breaking Hammer, and Measuring Device - A method and measuring device for determining the usage rate of a breaking hammer, and to a rock breaking device. The measuring device comprises a sensor for measuring a physical phenomenon caused by the operation of the percussion device. The measuring results are processed, and they are used to determine the start and end times of the operation of the percussion device. By means of a timing device, it is possible to determine the duration of an impact cycle which is added to a time counter. The durations of impact cycles added cumulatively to the time counter indicate the total percussion time of the breaking hammer. Impact pauses between impact cycles are also monitored, and pauses shorter than a predefined time limit are taken into account as part of the usage rate. | 10-04-2012 |
| 20140119489 | COUNTER APPARATUS - Of a counter apparatus, a first microcomputer and a second microcomputer communicate with each other and receive a crank signal with pulses. The first microcomputer detects a first pulse count number at a detection time point and transmits it to the second microcomputer. The second microcomputer detects a second pulse count number at a determination time point, which is an allowable delay time period later from the detection time point. The allowable delay time period is expected to elapse from the detection time point to when the first pulse count number is received by the second microcomputer. The second pulse count number is compared with a determination value, which is the sum of (i) the first pulse count number and (ii) the largest integer not greater than the quotient of T2/T1, T1 being a pulse period of the crank signal, T2 being the allowable delay time period. | 05-01-2014 |
