摘要： A distance measuring device for an automatic focusing camera includes a light receiving lens and a multilayer printed circuit board mounted on a holder. A potting frame is provided on the lens-facing side surface of the printed circuit board. An optical sensor and an IC are both mounted within a space enclosed by the potting frame and simultaneously sealed by a protecting resin. Resistors and capacitors of a distance measuring circuit are mounted on the opposite surface of the printed circuit board. The two surfaces of the printed circuit board are connected to each other via a through hole to construct the distance measuring circuit. The protecting resin transmits light having specified wavelengths. The light reflected from a subject to be photographed is received by the optical sensor after passing through the protecting resin, and the distance to the subject is calculated on the basis of the received light data.

摘要： In a step-up circuit for causing the emission of light of a distance measuring light emitting element, the step-up circuit outputs a step-up voltage from one terminal of a step-up capacitor. A step-up voltage level changeover circuit applies a step-up voltage to the capacitor every time the distance measuring light emitting element emits light that is higher than the step-up voltage in the normal state. The number of parts is reduced by eliminating a separate capacitor for light emission, the space for the circuit is reduced by using the capacitor having a small capacity, the soldering steps for fabrication of the circuit are automated; and the costs for assembly are ameliorated owing to the automation.

摘要： A distance measuring device may be constructed utilizing a reduced number of components by calculating distance on the basis of the duration of an integration. Pulsed light is projected toward an object. A selecting circuit selectively outputs one of a pair of output voltages from two current-voltage converting circuits, each of which is connected to a position sensitive device which is configured to receive light reflected from the object. A variable-gain amplifying circuit is used for amplifying the selected output voltage and for producing an amplified output voltage. The output voltage of the amplifying circuit is integrated by an integrating circuit. Reference voltage generating circuitry generates two reference voltages having different levels and a comparing circuit compares the output voltage of the integrating circuit with one of a pair of reference voltages. Gain selecting circuitry is used for determining the gain of the variable-gain amplifying circuit on the basis of the output result of the comparing circuit. The distance to the object is determined in accordance with the duration of time that integration is performed by the integrating circuit until the integrated output voltage exceeds one of the reference voltages. Thus, distance may be determined in accordance with the magnitude of the integrated output voltage, the number of times integration is performed or the number of light projections performed by the device.

摘要： A distance measuring device for ensuring accuracy of the positional relationship between the optical axis of a light-receiving lens and the optical center of a light-receiving element obtains distance information data by measuring the distance to a target plate which is 1 meter from the distance measuring device. If the distance information is not smaller than 1.625 meter, a switch is connected to one pair of terminals and the difference between reference output data stored in a control circuit and output data of an AF-IC obtained when the distance to the target plate is measured with the switch connected to the pair of terminals is calculated and stored in a memory circuit. When the value of the distance information data is not greater than 0.375 meter, the switch is connected to another pair of terminals, and output deviation data is stored in the memory circuit 11 in the same way. When the value of the distance information value is smaller than 1.625 meter and greater than 0.375 meter, the switch is connected to a further pair of terminals, and output deviation data is stored in the memory circuit in the same way.

摘要： In order to reduce noise in a controlling circuit including digital circuitry and analog circuitry constructed together on a single CMOS integrated circuit, a regulator is constructed as part of the integrated circuit. A power supply is directly connected to the digital circuitry, and a voltage output of the regulator is supplied to the analog circuitry. The output state of the regulator may be controlled by a switch. Degradation of the performance characteristics of the analog circuitry while the digital circuitry is being operated can be prevented by electrically isolating the power supply to the digital circuitry from the power supply to the analog circuitry. Since the regulator is built into the integrated circuit, the number of externally provided components is thereby reduced, further contributing to the downsizing of an electronic device such as a camera. Furthermore, even when the power supply of the digital circuitry fluctuates greatly, the effects on the analog circuitry are minimized.

A first memory stores output signals of the first and second signal processing circuits, the output signals being generated upon operation of the light projecting device when the first selecting device selects the first output signal and the second selecting device selects the second output signal. A second memory stores output signals of the first and second signal processing circuits, the output signals being generated upon operation of the light projecting device when the first and the second selecting devices both select the first output signal.

摘要： A power supply system for supplying a grid power to a building includes a power generator, a power storing device, and a power controller. The power generator generates off-grid power from a predetermined energy. The power storing device stores the grid power and the off-grid power and supplies the stored power to the building. The power controller controls consumptions of the grid power and the off-grid power. The power controller calculates predicted consumption data related to power consumed in the building and predicted generation data related to power generated by the power generator. The power controller calculates a charging-discharging schedule for the power storing device based on the predicted consumption data and the predicted generation data by formulating the charging-discharging schedule as a mixed integer programming problem.

摘要： A method is provided for device detection by a base station comprising receiving a plurality of signals over a preamble subframe from an endpoint. The plurality of signals are attempting to access an access group of the preamble subframe. Additionally, the plurality of signals are received on a random access channel using a wireless network. Further, the plurality of signals have a plurality of last gasp messages (LGMs). The method additionally comprises determining an allowable rate of collisions for the plurality of signals and determining an actual rate of collisions for the plurality of signals. The method includes increasing the size of the access group allocated to the plurality of signals having the plurality of LGMs, based on whether the actual rate of collisions exceeds the allowable rate of collisions.
