In a system of spaced surface markers disposed on a travel surface, each surface marker includes a housing, a power system within the housing producing electrical power from solar energy or vibration, and wireless transceiver(s) within the housing wirelessly communicating with neighboring surface markers. One surface marker relays data from and to another, while a third surface marker relays data from and to a network connection to a remote network. All surface markers may communicate via WiFi. The travel surface may be for vehicles. Each surface marker may communication with a vehicle or mobile device within communication range, to provide location or other information.

The invention relates to a method for operating a transmission device of a lighting device comprising an illumination device, wherein the transmission device is arranged in or immediately on the illumination device and wirelessly emits a radio signal with identification signals that are specific to the transmission device, wherein the radio signal is emitted according to exactly one predetermined radio standard, wherein the radio signal contains the specific identification data at least in two data formats that are different from each other.

A method for locating an animal using radio waves. In radiolocation, a large number of possible calculation results for the location of the animal arise. Using the results of previous measurements and calculations with regard to the possible locations of the node to be located, stochastic calculations are used to filter out, from the plurality of the current location calculation results, that result which in fact applies with the highest probability. Acceleration values which are measured at the animal are used in the stochastic calculations. It is assumed that with increasing measured acceleration values the probability increases that there can also be relatively large distances between temporally successive locations of the node to be located.

A delivery device includes an image capture device for generating delivery image data of a delivery at a service address. A processor executes a delivery application to bidirectionally communicate delivery data with the delivery data server via the network interface, wherein the delivery data includes a delivery tracking number and the delivery image data. The delivery data server processes the delivery data to provide a delivery confirmation to a customer at the service address, wherein the delivery confirmation includes the delivery tracking number and the delivery image data.

An information processing system is disclosed. A device conducts a predetermined process by sensing a neighboring radio signal state. An information processing apparatus is connected to the device. In the information processing apparatus, multiple sets of neighboring definition information in which a neighboring signal state is defined, is stored in a storage part. Neighboring definition information depending on a location indicated by location information is specified from among the multiple sets of neighboring definition information based on the location information received from the device. The specified neighboring definition information is sent to the device. In the device, the predetermined process using the neighboring information received from the information processing apparatus is conducted. Sensing information indicating a process result acquired by the predetermined process is generated.
