A radio control transmitter, comprising a grip portion gripped by an operator when performing remote control of a control target, a base portion disposed at one end of the grip portion, and a head portion disposed at the other end of the grip portion and having an operating member for controlling the control target, transmits a control signal to the control target in response to an operation of the operating member including a wheel that controls a traveling direction of the control target. The radio control transmitter further comprises a switch mechanism including an operating lever, to which the wheel is detachably attached, disposed at an outer peripheral portion of the switch operating member attached to a main body fitting portion of the head portion, and a switch disposed in the switch operating member to activate a pre-assigned function when the operating lever is pulled toward an axially outer side of a rotation shaft of the wheel.

An IC card communicates with a reader/writer, which is induction-type read/write communication equipment, in a contactless manner. A power supply control circuit detects presence or absence of power reception in accordance with an output voltage of a power receiving circuit, detects presence or absence of predetermined communication by using an electronic functional circuit, starts to charge an electrical energy storage device by using a charging circuit when there is not the predetermined communication immediately after power reception is detected, and supplies power from a voltage conversion circuit to the electronic functional circuit without starting to charge the electrical energy storage device by using the charging circuit when there is the predetermined communication immediately after power reception is detected.

Methods, systems, and devices for wireless communications are described. Some wireless networks may maintain up-to-date location information for the UE by periodically determining the location the UE using a low power transponding mechanism while the UE is in an inactive state. The UE may monitor a first beam to receive one or more transponder search signals during one or more transponder occasions, and between paging attempts from one or more of the base stations of the network. The UE may receive the one or more transponder search signals, and may transmit a transponder response message to a base station including a UE identifier associated with the inactive state. The base station may receive the transponder response message, and may conduct various location measurements for the UE using the transponder response.
