  • Patent number: 10095566
    Abstract: An operator control element in a motor vehicle generates an activation signal as a function of the activation of the operating element, and a control unit receives the activation signal and measures a signal length of the activation signal, and signals the activation if the signal length becomes greater than a predetermined debounce time. Despite possible incorrect triggering of the activation signal owing to voltage fluctuations, the debounce time is to be short. The control unit determines for this purpose an operating parameter, and on the basis of the operating parameter it is detected that a supply voltage, made available at the control unit, satisfies a predetermined instability criterion, and when the instability criterion is satisfied the control unit delays the measurement of the signal length for a predetermined blocking time.

    Abstract: An electric power generation control system for a vehicle, which enables generation of electric power by a generator as much as possible while preventing an electrical component from being overheated by power generation by the generator. The electric power generation control system selectively switches a mode of the generator between first and second modes in which an instruction voltage is higher and not higher than an allowable voltage of a wire harness, respectively. A counter value is counted up in the first mode and down in the second mode. When the counter value has reached a higher limit value, the first mode is inhibited and the power generation mode is set to the second mode. This increase the proportion of an execution time period of the first, and accordingly, when a possibility of overheating the wire harness becomes high, the instruction voltage is lowered.

  • Patent number: 8860248
    Abstract: A demand response unit (DRU) interposed between a utility's electrical power line (PL) and at least one load (L1-Ln) to which power is supplied by the utility over the line. A detector (Fdet or Vdet) measures a characteristic (frequency F, voltage V) of an electrical waveform (W) by which power is transmitted by the utility to the load. The detector determines both when the measured frequency or voltage exceeds a predetermined threshold for a first predetermined period of time; and, if the threshold is exceeded, when the frequency or voltage exceeds the second predetermined threshold for a second predetermined period of time. For this purpose, the detector processes a predetermined number of intervals of the waveform and produces an average value of the characteristic which is compared to the threshold. This is done to reduce the effect of extraneous events which may temporarily change the value of the frequency or voltage.

    Abstract: The present disclosure provides apparatus, systems, and methods for preventing out-of-synchronism closing between power systems. An intelligent electronic device (IED) apparatus may include a control component and a delay component. The control component is configured to selectively control opening and closing of a breaker. The control component selectively outputs a close signal to cause the breaker to connect a first portion of a power delivery system to another portion of the power delivery system. The delay component is configured to delay output of the close signal to the breaker. The delay component includes circuitry independent from control by the control component and the delay component is inconfigurable from a remote location.

  • Patent number: 8632199
    Abstract: A lamp apparatus include a lamp body, at least an alternating current light-emitting diode and a plug. The alternating current light-emitting diode is disposed on a lamp body. The plug is electrically connected to the alternating current light-emitting diode. In lamp apparatuses utilizing AC LED, heat generated thereby is almost concentrated on chips. Compared with conventional lamp apparatuses utilizing DC LEDs, heat generated thereby is distributed on chips and outer rectifier. In lamp apparatuses utilizing AC LEDs, heat generated thereby is almost concentrated on chips because AC LEDs operate directly with AC electric power, omitting a rectifier and preventing power loss during operation of power rectification. Therefore, the heat accumulated on the chips of the AC LEDs is enough to be used to evaporate essential oil. In another embodiment, the invention utilizes low-resistance pure water surrounding the AC LED to dissipate its heat.

  • Patent number: 8538596
    Abstract: A lighting controller may optimize a timeout value of a lamp based on the goals of saving energy and providing occupant comfort. The lamp may illuminate a lighting area. The lighting controller may determine a false-negative rate for the lamp from sensor data that represents a frequency at which the lamp is timed out while the lighting area is occupied. The lighting controller may adjust the timeout value of the lamp over time so that the false-negative rate approaches a threshold false-negative rate. The false-negatives and occupancy periods may be detected from spikes in time distributions of motion data. The amount of energy that the lamp would consume at an increased timeout value of the lamp may be determined from motion data stored while the timeout value of the lamp is at an initial timeout value.

    Abstract: A power control module which can be used to automatically open a power circuit for electrically operated devices, particularly battery operated devices, during predetermined periods of non-use. A timer is reset by a motion detector indicating continuing use. The timer controls a transistor switch which closes and opens the power circuit as required. The timing interval can be user-selected e.g., by programming a microprocessor controller. The transition time between conductive and non-conductive states of the transistor can also be controlled to prolong the life of incandescent bulbs or other sensitive load devices.

The power control unit is driven by power supplied from a power source. The power switch outputs a detection signal to the power control unit. The timer unit outputs a switch-on signal for giving an instruction to turn on the switch. The power supply switch switches between connection and non-connection of the power source and a load. The connection instruction unit outputs a connection instruction signal for connecting the power source to the load. The power control unit outputs a stop signal for stopping the output of the switch-on signal to the timer unit before a time point at which the predetermined time elapses when the power is supplied from the power source. The power control unit outputs the switch-on signal to the connection instruction unit.

  • Patent number: 8484497
    Abstract: An integrated circuit 2 is provided with a first power supply conductor 8 coupled via header transistors 14 to 26 to a second power supply conductor 10. Logic circuitry 4, 6 draws its power supply from the second power supply conductor. When switching from a sleep mode to an operating mode the header transistors 14 to 26 are divided into a plurality of sets of transistors which are switched on in a predetermined sequence using controller circuitry 28. The controller circuitry 28 senses the voltage of the second power supply conductor 10 to determine when each set of header transistors should be switched on. In this way, the in-rush current within the integrated circuit 2 associated with the switch from the sleep state to the operating state can be held within a predetermined range of a target in-rush current.
