The present invention relates to a system for determining the position, the orientation and/or the movement of a beacon, said system comprising at least one receiver and one beacon, the beacon comprising a transmitter, the transmitter of the beacon being designed to emit electromagnetic waves in a frequency band and the receiver having means which are designed to receive the waves and to determine a position, orientation and/or movement of the beacon therefrom, the system having at least one further beacon, the frequency band of the transmitter of the further beacon or the frequency bands of the transmitters of the further beacons differing from the frequency band of the transmitter of the beacon.

In an aspect, a method of operating a processing device includes obtaining location information of a target device, transmission time information of first one or more beacons transmitted by the target device, or transmission channel information of the first one or more beacons; and configuring a first set of electronic shelf label (ESL) devices to perform a targeted scanning operation based on the location information, the transmission time information, or the transmission channel information. The method of operating the processing device further includes receiving one or more targeted scanning reports from the first set of ESL devices based on the targeted scanning operation, and engaging in a positioning procedure for determining an estimated location of the target device based on the one or more targeted scanning reports.

Systems and methods for improved geolocation in a network are disclosed. An end node may transmit a signal. The signal may be received by a plurality of computing devices. Receipt times of the signal at the plurality of computing devices may be used to determine a location of the end node.

A barcode-reading device can be configured to transmit a beacon message under certain circumstances in which the barcode-reading device may be lost, or may be likely to become lost, such as when a barcode-reading device becomes unintentionally disconnected from a base station. Intermediary systems can be configured to periodically listen for beacon messages from barcode-reading devices. When an intermediary system receives a beacon message, the intermediary system can determine whether the beacon message was sent by a barcode-reading device. If it was, the intermediary system can forward the beacon message (or at least some of the contents of the beacon message) to a remote server. In response to receiving a forwarded beacon message, a remote server can generate and send a notification message to one or more recipients. The notification message can also include information that indicates (or is in some way related to) the location of the barcode-reading device.

Provided is a wireless locator. The wireless locator includes a locator body and a charging connector movably connected to the locator body. The locator body includes an accommodation groove and a first electrical connection structure. The charging connector includes a second electrical connection structure and a plug-in tongue which may be accommodated in the accommodation groove. When the wireless locator is charged, the plug-in tongue is taken out from the accommodation groove, the first electrical connection structure of the locator body and the second electrical connection structure of the charging connector are connected, and the plug-in tongue is connected to an external charging interface. In this way, a rechargeable battery in the wireless locator is charged.

An attachment is operable to have therein or thereon a transmitter to periodically transmit a first wireless signal which includes a piece of first attachment information relating to the attachment and which is compliant with a near field communication standard. A portable device is operable to transmit a second wireless signal which includes a piece of second attachment information relating to the attachment to be attached to a hitch of a working vehicle and which is compliant with the near field communication standard. A vehicle controller of the working vehicle is configured or programmed to perform a selecting process to select, according to a predetermined condition, a piece of attachment information included in one of one or more of the first and/or second wireless signals received by a receiver, and perform a predetermined process based on the piece of attachment information selected in the selecting process.

Described is a sensor that is used to determine the location of an object with additional features that create human-recognizable feedback that identifies an individual object, solving the problem of needing a specialized device to perform the identity step. The location data is sent to Edge or Cloud devices that contain the raw location data. This data has location information that is used to automatically update an Enterprise Manufacturing System (EMS) or other system critical location. This invention integrates multiple location technologies to overcome the limitations of a single method. In addition to updating business systems (EMS), the cloud devices display location data in a multimodal (maps & digital twin) system, allowing operators to visualize and track the movement and location of objects. The combination of coordinated 2D mapping and 3D digital twin representations creates a superior understanding of an object's location and orientation with respect to other objects in its vicinity leading to exact identities within the workflow.

A method of estimating a relative position of a first robot with respect to a second robot at a current timestamp, wherein a first ultra-wideband (UWB) tag is installed on the first robot, the first UWB tag being a rotating tag configured to move in a circular path about a centre of rotation on the first robot, wherein a second UWB tag is installed on the second robot, the method comprising: receiving an estimate of the relative position of the first robot with respect to the second robot calculated at an earlier timestamp; obtaining rotating tag offset values of the first UWB tag with respect to the first robot at the earlier timestamp and at the current timestamp; obtaining a velocity value of the first robot at the earlier timestamp; obtaining a velocity value of the second robot at the earlier timestamp; obtaining distance values between the first UWB tag and the second UWB tag at the earlier timestamp and at the current timestamp; and calculating the relative position of the first robot with respect to the second robot at the current timestamp according to: the estimate of the relative position calculated at the earlier timestamp, the rotating tag offset values of the first UWB tag with respect to the first robot at the earlier timestamp and at the current timestamp, the velocity values of the first robot at the earlier timestamp, the velocity values of the second robot at the earlier timestamp, and the distance values between the first UWB tag and the second UWB tag at the earlier timestamp and at the current timestamp.

A method and system for enabling the determination of a position of a receiver within a space includes transmitting a beacon signal from each of a plurality of beacon devices located at different locations within the space. The beacon signal transmitted from each beacon device has a unique information component and may have a unique frequency pattern of multiple frequencies. Each beacon signal can be distinguishable from the beacon signals transmitted from any other of the beacon devices based on the combination of its unique information component and its unique frequency pattern. The beacon signals are received at a receiver. At the receiver, for each beacon signal of a working subset, time-delay information of the received beacon signal is determined and multilateration is applied to determine the position of the receiver based on the location of each beacon device of the working subset.

A positioning signal sending method and apparatus are provided. A first signal is generated, where duration of a first rising edge of the first signal is less than duration of a first falling edge, the duration of the first rising edge is duration of a rising edge of a main lobe waveform of the first signal, and the duration of the first falling edge is duration of a falling edge of the main lobe waveform of the first signal; and the first signal is sent. In embodiments of this application, rising time of a main lobe waveform of a signal generated is short, and shorter rising time of the main lobe waveform is more conducive to distinguishing two adjacent paths or identifying a first arrival path of a received signal.
