The disclosure includes a system and method for providing charging services to mobile client devices. The system includes a processor and a memory storing instructions that, when executed, cause the system to: estimate a departure time for a mobile client device; determine a target state of charge at the departure time for a battery system in the mobile client device; determine one or more available charging periods and one or more demand response event periods; determine one or more amounts of power to be discharged from the battery system during the one or more demand response event periods; determine one or more charging time slots within the one or more available charging periods based on the target state of charge and the one or more amounts of power to be discharged; and charge the battery system using the one or more charging time slots.

Charging management based on demand response events

The disclosure includes a system and method for charging a target object wirelessly. The system includes a processor and a memory storing instructions that when executed cause the system to: receive data describing a code from a target object, the code being stored on a tagging device and configured to be read wirelessly by a reading device associated with the target object; verify the code; determine that a location associated with the target object satisfies a safe charging range responsive to the verification of the code, the verification of the code indicating a charging distance between a power transmitter and a power receiver associated with the target object satisfies a safe charging distance; and instruct the power transmitter to wirelessly transmit power to the power receiver associated with the target object responsive to determining that the location of the target object satisfies the safe charging range.

A radar system includes an arithmetic processing unit, which calculates the second derivative of the intensity of a reflected wave and determines whether a target is an upper structure or a vehicle, based on the second derivative. Alternatively, the arithmetic processing unit decomposes the waveform of the intensity of the reflected wave into frequency components and determines whether the target is an upper structure or a vehicle, based on the intensity of a predetermined frequency component.

Radar system and detection method

A radar system includes an arithmetic processing unit, which sends a warning command to a warning device when a local minimum point of the intensity of the reflected wave from a target within a predetermined detection range is detected. By determining whether it is necessary to send a warning command based on whether there is a local minimum point of the intensity within the detection range, it is made possible to determine whether it is necessary to send a warning command more quickly as compared to the conventional system.

An imaging mechanism captures an image of a face of a driver of a vehicle. A first image processor performs image processing on a wide portion of the face of the driver in a first image using a first image captured by the imaging mechanism. A second image processor performs image processing on a part of the face of the driver in a second image captured by the imaging mechanism at a higher exposure than the exposure of the first image, using the second image.

In an electronic apparatus, a first microcomputer is monitored by a second microcomputer, which periodically transmits data relating to a main function to the first microcomputer to be processed. The first microcomputer periodically updates a variable value, performs a predetermined calculation operation whose final result should be a specific fixed value, adds that final result to the updated variable value to obtain a sum value, and transmits the sum value and updated variable value concurrently to the second microcomputer. The second microcomputer determines that the first microcomputer is operating abnormally if the difference between the received sum value and variable value is not equal to the specific fixed value.

A radar sensor receives a radar wave signal through a radome in each of antennas while judging existence of an attenuating thing in a detecting unit. This unit extracts a maximum level channel from receiving channels assigned to the antennas every modulation period, calculates a difference in signal level between the maximum level channel and each receiving channel every modulation period, sets each receiving channel corresponding to large level differences in one measuring period including plural modulation periods as a candidate channel every measuring period, increments a preliminary variable of each candidate channel every measuring period, increases a final variable each time the preliminary variable of at least one receiving channel reaches or exceeds a preliminary value in one measuring period, and judges in response to the final variable reaching a final value that the attenuating thing attenuates the radar wave directed toward the random.

An object is to provide a cheap digital beamforming radar apparatus. For achieving it, the radar apparatus of the present invention comprises a transmit section for radiating a transmit signal in the form of an electromagnetic wave, an array antenna comprised of a plurality of antenna elements for receiving an electromagnetic wave re-radiated from an object when the electromagnetic wave of the transmit signal reaches the object, as a receive signal, a switching device for connecting either one of the antenna elements to a predetermined terminal in an alternative way by a switching signal, a receive section for downconverting the receive signal obtained from the predetermined terminal by use of part of the transmit signal to generate a difference signal between the transmit signal and the receive signal and converting this difference signal to a digital signal, and a digital signal processing section for subjecting the digital signal from the receive section to a predetermined process to detect a distance to the object or a relative velocity of the object.
