  • Patent number: 10845376
    Abstract: An aspect of the present invention more reliably prevents a false detection of lifting of the electronic device, in an information processing device mounted on an electronic device. A first lifting determination section (64A) determines that a mobile terminal (1) has been lifted, in a case where the following conditions (i) and (ii) are satisfied after a manner of change in acceleration detected by an acceleration sensor (11) over time has satisfied a predetermined acceleration condition: (i) a standstill determination section (63) determines that the mobile terminal (1) is in a standstill state; and (ii) a result of detection by a proximity sensor (14) indicates a transition from proximity to non-proximity within a predetermined time range, the predetermined time range being set with reference to a standstill determination completion time point at which the standstill determination section (63) has completed determination.

  • Patent number: 10704922
    Abstract: In order to avoid erroneous count of the number of steps in a case where a user is using a traveling means other than walking, a step counting section (13) switches between acceleration value change period ranges for counting the number of steps, depending on whether a traveling means determining section (11) determines that the user is walking or that the user is using a traveling means other than walking.

  • Patent number: 10667217
    Abstract: An embodiment of the present invention provides an information processing device which reduces the possibility of a false detection of lifting of an electronic device. A standstill determination section (63) determines that a standstill condition is satisfied in a case where a dispersion of acceleration detected by an acceleration sensor (11) is (i) within a predetermined standstill reference range and (ii) outside a predetermined complete standstill reference range. Then, in a case where the standstill determination section (63) determines that the standstill condition is satisfied, a lifting determination section determines that an electronic device (1) has been lifted.

  • Publication number: 20180136742
    Abstract: A device of the present invention makes it possible to detect lifting of the device itself with a reduced possibility of false detection. The device of the present invention includes a lifting control section (52) which determines, under the following conditions, that the lifting has been carried out. The conditions are as follows: the lifting control section (52) obtains acceleration information indicative of acceleration detected by the acceleration sensor (11); a waveform representing values of acceleration indicated by the acceleration information with respect to elapsed time has a maximum value and a minimum value; the acceleration is greater than a first predetermined value during a first predetermined period including a time point of the maximum value; and the acceleration is lower than a second predetermined value during a second predetermined period including a time point of the minimum value.

  • Patent number: 9692877
    Abstract: To reduce the number of erroneous detections and power consumption and increase the speed of a response to an operation, a portable terminal (10) includes (i) a determining unit (22) configured to determine whether a sensing signal output from at least one of a first electrode (1A) and a second electrode (1B) has an absolute value of not less than a first threshold or not greater than a second threshold and (ii) a determination period control unit (23) configured to perform a process of shortening a determination cycle in a case where the determining unit has initially determined that the absolute value of the output is not less than the first threshold or in a case where the determining unit has initially determined that the absolute value of the output is not greater than the second threshold.

  • Patent number: 9553975
    Abstract: Avoided is falsely detecting a hand of a usual user being in contact with a contact sensor, instead of detecting an object, such as water, having a high dielectric constant being in contact with the contact sensor. A smartphone (1) includes a contact determination section (101) which determines that (i) a hand is in contact with a contact sensor (11) in a case where an output value outputted by the contact sensor (11) is not lower than TH1 and lower than TH3 and (ii) an object, such as water, having a high dielectric constant is in contact with the contact sensor (11) in a case where the output value is not lower than TH3.

  • Patent number: 5764316
    Abstract: A lighting system has a light source (2), a liquid crystal dimmer plate (4) for scattering a desired quantity of light from the light source (2), and a control power supply (5) for controlling a light scattering rate or effect of the liquid crystal dimmer plate (4). A light component transmitted through the liquid crystal dimmer plate (4) can be controlled by controlling the scattering effect of the dimmer plate (4). The so controlled light can be used as an illuminating light for a camera for example.

  • Patent number: 5631665
    Abstract: An illumination apparatus includes a liquid crystal device (L) disposed in the optical path of light projected from a light source (P) and a driving circuit (D) connected to the liquid crystal device for applying a special driving voltage to a composite film (1) of the device (L). The applied driving voltage alternately causes the composite film (1) to attain an opaque state and a transparent state. The time periods of the alternating voltage pulses are varied, thereby changing the ratio of the duration of the opaque state to the duration of the transparent state per unit time period, and thus controlling the power of light transmitted through the composite film (1) without undesirably altering the color spectrum of the transmitted light.
