Patent number: 10382865Abstract: An angle calculator calculates, based on acceleration detected by an acceleration sensor, a tilt angle of a transceiver with respect to the vertical direction. A selector (i) selects a first audio filter to operate if the tilt angle is less than a threshold angle, or (ii) selects a second audio filter to operate if the tilt angle is equal to or greater than the threshold angle. The second audio filter has a lower cutoff frequency that is higher than the lower cutoff frequency of the first audio filter.Type: GrantFiled: December 6, 2018Date of Patent: August 13, 2019Assignee: Icom IncorporatedInventor: Yoshio Sekiyama

Patent number: 10083579Abstract: An electronic device including a submersion detector, an illuminant provided inside a casing, a lighting circuit, a controller, an unnecessary part that is unnecessary for lighting the illuminant. The submersion detector detects submersion of the electronic device and retrieval of the device. The submersion means that the electronic device falls onto or into water. The retrieval means that the electronic device is retrieved from water. The lighting circuit lights the illuminant in response to an input of a lighting signal. The controller lights the illuminant by generating and outputting the lighting signal to the lighting circuit for a period of time from the submersion at least until the retrieval. In a case where the unnecessary part is supplied with power when the submersion detector detects the submersion, the controller stops the supply of the power to the unnecessary part at least for the above period of time.Type: GrantFiled: April 26, 2016Date of Patent: September 25, 2018Assignee: ICOM INCORPORATEDInventor: Yoshio Sekiyama

Patent number: 9854648Abstract: An electronic device including a submersion detector, illuminants, a lighting circuit, a controller, and an orientation detector. The submersion detector detects submersion of the device and detect retrieval of the device. The illuminants are arranged inside a casing such that at least one of the illuminants is visible from above water when the device is submerged in any submersion orientation. The lighting circuit lights up at least one of the illuminants in response to an input of a lighting signal. The controller generates and outputs the lighting signal to the lighting circuit for a period of time from the submersion at least until the retrieval so as to light up the at least one of the illuminants. The orientation detector detects a submersion orientation of the device. Only the at least one of the illuminants that is visible from above water lights up, in accordance with the detected submersion orientation.Type: GrantFiled: April 26, 2016Date of Patent: December 26, 2017Assignee: ICOM INCORPORATEDInventor: Yoshio Sekiyama

Patent number: 9786135Abstract: A radio apparatus includes a control unit, a power unit, a distress key and a transmission unit. When the distress key is manipulated, a distress key manipulation signal is output to the control unit and the power unit. When the power unit receives the distress key manipulation signal during a power supply is stopped, the power unit supplies power to the control unit and the transmission unit. When the control unit receives power from the power unit, the control unit starts setting up the radio apparatus and counts a time that the control unit continuously receives the distress key manipulation signal. When the control unit continuously receives the distress key manipulation signal for a preset time or longer, the control unit outputs a power supply maintenance signal to the power unit, generates the distress signal, and causes the transmission unit to send the distress signal.Type: GrantFiled: March 3, 2017Date of Patent: October 10, 2017Assignee: ICOM INCORPORATEDInventor: Yoshio Sekiyama
