Abstract: An electronic device (1) includes: a positional information obtaining section (21) for obtaining positional information; a boarding determining section (12) for determining whether or not a user has boarded or exited a vehicle; and a frequency switching section (14) for switching a frequency, at which the positional information is obtained, from a first frequency to a second frequency in a case where it is determined that the user has boarded or exited the vehicle.

Abstract: An embodiment of the present invention not only protects user's privacy but also reliably notifies a user of a change in state of an external communication device. A state change notification device (1) includes: an information receiving section (11) that receives state change information in a case where a change in state occurs in a device (100, 200, 300, or 400) in which an external communication device (500) or the state change notification device (1) is provided; and an expansion control section (12) that controls inflation of a balloon (24) provided in a wristwatch-type communication device (100) so that an inner pressure of the balloon (24) will be a user-perceivable pressure.

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.

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.

Abstract: A receiver device (1) of the present invention switches between a bone conduction receiver (16) and an air conduction receiver (17) depending on an area or a shape of a contact region of a touch panel (10) provided in the receiver device (1) which region is in contact with a user.

Abstract: In this surface light source device, light is incident from a plurality of point light sources 2 arranged on a one side end surface of a light guide plate 1, is reflected on a light reflecting surface 11 on a rear surface of the light guide plate 1, and is emitted from a front surface of the light guide plate 1. The point light sources 2 comprise white light emitting diode elements. Two white light emitting diode elements out of six of the white light emitting diode elements having chromaticity outermost from a center of an aimed chromaticity range in opposite hue directions are arranged in an approximately center of a group of the white diode elements.
