Abstract: A second device for measuring a distance from a first device is provided. The second device includes an electromagnetic receiver configured to receive an electromagnetic signal transmitted by the first device at a first time and a sound receiver configured to receive a sound signal transmitted by the first device at a second time. The electromagnetic signal and the sound signal are transmitted substantially at the same time. The second device also includes a processor configured to approximate the distance of the second device from the first device based on the first time, set a capturing window for capturing the sound signal based on the approximated distance and capture the sound signal within the set capturing window. The processor is configured to determine the distance of the second device from the first device based on the first time and the captured sound signal.

Abstract: A first device is mounted on a robot, and signals are transmitted between the first device and at least one second device placed at a certain physical location. Based on the signals, one or more positions in a coordinate system of the robot are determined. For this purpose, the robot may move the first device so that the signals can be transmitted for different physical locations of the first device.

Abstract: A proxy device includes a processor circuit, a memory coupled to the processor circuit, and a network interface coupled to the processor circuit. The processor circuit is configured to function as a proxy for network communications to and from an internet of things, IoT, device that is located within a same home network as the proxy device. The processor circuit is configured to determine that the IoT device is in sleep mode in which the IoT device is unable to send or receive network communications, and, in response to determining that the IoT device is in sleep mode, to store network communications received from a remote server on behalf of the IoT device until determining that the IoT device has entered active mode in which the IoT device is able to send and receive network communications.

Abstract: A distance measuring system is provided that includes a first device having a transmitter configured to simultaneously transmit an electromagnetic signal and a sound signal. The distance measuring system also includes a second device located at a distance from the first device. The second device is configured to receive the electromagnetic signal at a first time and receive the sound signal at a second time, and calculate the distance of the second device from the first device based on a difference between the first time and the second time.

Abstract: A system includes a moveable element adapted to move relative to a coordinate system defined for a robot, an object detection transceiver unit adapted to be mounted on the moveable element, and a controller. The controller controls the object detection transceiver unit to emit a signal and obtain a return signal for an operational cell of the robot at each of a series of predetermined positions to emulate a transceiver aperture larger than an aperture of the object detection transceiver unit. A location corresponding to a marker present in the operational cell is determined from the return signals. A predetermined operation is carried out where the predetermined operation includes using the determined location to guide movement of the robot.

Abstract: Signals are transmitted between a device placed on an object and at least one further device. Based on measurement of the signals transmitted between the device and the at least one further device, a position of the object is determined. Further, data associated with the object are stored in the device. The stored data are then transmitted from the device.
