Patent number: 8250398Abstract: An electric vehicle charging station, which does not include a battery-backed Real Time Clock, is in a charging station network managed by a charging station network server. Upon booting, the charging station requests actual real time from a remote source. While the charging station has not received the actual real time, it records the time of charging station specific events in a local system time format that resets when the charging station loses power. The charging station maintains the events recorded in their local system time until actual time is received. When actual real time is received, the charging station synchronizes its local system clock with the actual real time and converts the time of each event into real time format. When actual time is received, the charging station converts the time of each event into real time format. After the time of the events are converted to real time format, they are communicated to the charging station network server for further processing.Type: GrantFiled: February 19, 2010Date of Patent: August 21, 2012Assignee: Coulomb Technologies, Inc.Inventors: James Solomon, Hongfei Cheng

Patent number: 7385879Abstract: A radio-controlled clock (RCC) for receiving and decoding a transmitted time signal to display a precise time in accordance with a time standard. A light emitting diode (LED) display emits sufficient light for easy readability under all lighting conditions, including the time numerals. A signal reception indicator remains lit if the RCC has successfully decoded a time signal. If the time signal is currently being received and decoded, the signal reception indicator flashes. If the decoding is unsuccessful, the signal reception indicator will be unlit until the next decoding attempt. A power transformer to supply current to electronic circuitry contained within in the housing of the RCC is located in the power line cord, as at the plug end, to minimize electromagnetic interference with the decoding of the time signals. A signal strength indicator may have multiple segments to indicate if the received signal is strong, medium, weak or too weak for decoding.Type: GrantFiled: March 10, 2006Date of Patent: June 10, 2008Assignee: Equity Industries, Inc.Inventors: Keith Kibiloski, Charles Wong Tak Chung

Patent number: 6548997Abstract: A novel and useful mechanism for measuring the time duration between asynchronous events. The mechanism utilizes two metastability resolvers, one for detecting the rising edge of the input signal and one for detecting its falling edge. The input signal is typically assumed to have some known nominal clock rate, but its exact frequency and phase (timing of transitions) are not known. Each of the two metastability resolvers comprises two branches of cascaded flip flops, each clocked off the rising edge and falling edge of a fast clock. Each metastability resolver functions to output an edge event signal and a clock phase signal indicating which edge of the fast clock the rising (or falling) edge of the data signal was closer to. The edge event signals are used to start and stop a counter clocked off the fast clock. The clock phase is used to correct (i.e. compensate) the counter value depending on which half cycle of the fast clock the rising and falling edge of the data signal arrived in.Type: GrantFiled: August 3, 2001Date of Patent: April 15, 2003Assignee: Texas Instruments IncorporatedInventors: Alexander Bronfer, Eldad Falik

Patent number: 6205090Abstract: A self adjusting clock system operable to provide a uniform time display on clocks throughout a facility including a master time-keeper, a plurality of slave time-keepers, and a time-keeping correction apparatus for correcting time of the slave time-keepers in accordance with the master timekeeper. The master time-keeper keeps the correct time and is operable to generate a master signal representative of a time correction. This master signal is then received by the time-keeping correction apparatus and analyzed in combination with other applicable information. The time-keeping correction apparatus supplies a slave correction signal to the slave time-keepers. The slave time-keepers independently keep and display the slave time-keeper time and respond to the slave correction signal to correct their slave time-keeper time when it deviates from the correct time kept by the master time-keeper.Type: GrantFiled: September 14, 1999Date of Patent: March 20, 2001Inventors: Rodney K.

Patent number: 5282180Abstract: A master/secondary clock system of the impulse type consisting of stepper motor driven secondary clocks and a master control unit. At five minutes before a predetermined registration time, for example 6:00, the sensor of each secondary clock movement is activated by a reverse polarity signal from the master control unit and a series of reset pulses are thereafter transmitted to the secondary clocks with each secondary clock stopping as the window in its drive train gear moves into alignment with the emitter and detector of its sensor mechanism. After this five minute pulse reset phase to correct clocks that are five or less minutes fast, the master control unit transmits a rapid pulse train so as to quickly move all of the remaining clocks to the 6:00 position with each clock being halted at the 6:00 position by movement of the window of its gear into alignment with the emitter and detector of the sensor mechanism of that clock.Type: GrantFiled: September 27, 1990Date of Patent: January 25, 1994Assignee: National Time & Signal CorporationInventors: Michael P.
