Disclosed is a portable terminal that can improve antenna characteristics regardless of the opened or closed state of a case. A portable terminal (1) comprises a first case (2) and a second case (3), a opening/closing sensor (45), which is able to detect an open state and a closed state, a circuit (32), comprising a ground (35), a power supply (36), and a signal processor (37), a first conductor (31), which is disposed in the first case (2) and connected to the ground (35), and a second conductor (400), which is disposed in the second case (3) and connected to the power supply (36), wherein the second conductor (400) is configured having a first part (41) and second part (42), which are adjacently disposed in the alignment direction of the first conductor (31) and second conductor (400) in the open state, and is further equipped with a controller (44) which, when the closed state is detected, provides high-frequency shielding of the second part (42) from the first part (41) and, when the open state is detected, provides high-frequency coupling between the first part (41) and second part (42).

An image formation apparatus for forming an image and test patterns. The image formation apparatus includes a storage unit that stores dither matrix data used to form the image and the test patterns; and an image formation unit that forms the test patterns based on the dither matrix data. A number of tones of the test patterns to be formed by the image formation unit is changed and the number of tones is determined based on a size of the dither matrix data and a number of bits per pixel within the dither matrix data.

A mobile electronic device comprises an RFID antenna section that sends and receives signals on a first useful frequency band, a main antenna section that sends and receives signals on a second useful frequency band, which is a higher frequency band than the first useful frequency band, an adjustment section that adjusts a resonance frequency of the RFID antenna section, and a control section that identifies a reactance value of the RFID antenna section based on the receiving sensitivity with respect to signals on the first useful frequency band and adjusts the resonance frequency of the RFID antenna section based on the identified reactance value by an adjustment section such that a high-order resonance frequency of the RFID antenna section is spaced apart from the second useful frequency band.
摘要:
The present invention is directed to an unpaved road detection system wherein a slip rate is calculated on the basis of wheel speeds detected by wheel speed sensors and a vehicle speed detected by a vehicle speed detection device. A linear acceleration sensor is provided for detecting an acceleration of the vehicle in a longitudinal direction thereof to produce a signal linearly proportional to the detected acceleration. A variation of the signal produced by the linear acceleration sensor corresponding to the variation of the slip rate is calculated. The variation of the signal is compared with a reference value. If the variation exceeds the reference value, it is determined that the vehicle is traveling on an unpaved road. The variation may be provided by calculating a difference between a first signal detected by the linear acceleration sensor when the slip rate exceeded a first reference rate, and a second signal detected by the linear acceleration sensor when the slip rate exceeded a second reference rate.
