Methods, computer program products and systems for providing video tracking. The method includes receiving a first signal from a radio frequency identification (RFID) tag. A location of the RFID tag is determined in response to the first signal. An image that includes the location of the RFID tag is recorded. The location of the RFID tag is marked on the image, resulting in a marked image.

Methods and systems directed to dispensing fluids, such as beverages, using wireless technology are provided. Aspects relate to a beverage dispenser with a dispensing system housing, a valve housing positioned exterior to the dispensing system housing and extending from the dispensing system housing. The valve housing may be configured to dispense a beverage and include self-contained electronics disposed within an interior area of the valve housing. In some embodiments, the beverage dispenser has one or more additional valve housings positioned exterior to the dispensing system housing. The valve housing may be configured to dispense a beverage and include self-contained electronics disposed within an interior area of the valve housing.

Methods and systems directed to dispensing, fluids, such as beverages, using wireless technology are provided. Aspects relate to a container, such as a beverage cup, having a wireless transceiver configured to transmit and/or receive wireless signals to a second wireless transceiver associated with a dispenser. The wireless transceiver may be configured to transmit electronic signals indicative that the container is validated to receive a beverage and whether it is properly located to receive the beverage from a valve of the dispenser. Further aspects of the invention relate to a beverage dispersing system having, a wireless transceiver. In one embodiment, the dispenser is configured to receive a return signal from a container indicative that the container is validated to receive a beverage and whether the container is properly located to receive a beverage from a valve of the dispenser.

A method and system for dividing tagged items into subsets. A region is split into subregions. For each subregion, a central tagged item having more adjacent tagged items in each subregion than any other tagged item in each subregion is determined, utilizing information that includes, for each tagged item in the region, a spatial location of each tagged item and a list of all other tagged items which are adjacent to each tagged item by being within a specified constant distance (Rlimit) from each tagged item. A virtual boundary is outlined around the central tagged item to enclose the central tagged item and a portion of the tagged items in each subregion which are adjacent to the central tagged item. The portion of the tagged items in each subregion consists of all, or less than all, tagged items which are adjacent to the central tagged item in each subregion.

Various embodiments relate generally to continuous monitoring of analyte values received from an analyte sensor system. In some example embodiments, there is provided a method that includes receiving sensor information, calculating and storing estimated analyte measurement values based upon the received sensor information. The method also includes determining one or more communication conditions, and instructing a transceiver to advertise to a first display device in accordance with one or more communication variables based upon the one or more communication conditions. The method then transmits the estimated analyte measurement values to the at least first display device. Related systems, methods, and articles of manufacture are also described.

Methods and systems are described for authorizing an item with an RFID tag to leave a facility. In one embodiment, a mobile device receives or determines an exit code (EC) to write into the tag in response to providing authorizing information. The EC may be based on information stored in the tag such as the tag's item identifier or other tag information (collectively an item identifier or II), a ticket value, other information such as the OC, a mobile identity or location, or any other suitable information. Upon verification of the EC, the tagged item is allowed to leave the facility. In another embodiment, the mobile device stores an item identifier (II) associated with the tag and provides authorizing information. Upon verifying the authorizing information and confirming that the stored II corresponds to the tagged item's II, the tagged item is allowed to leave the facility.

A Radio Frequency Identification (RFID) system including an RFID reader and a reader proxy authenticates itself to a verification authority. The proxy receives a proxy challenge from a verification authority and determines a proxy response based on the proxy challenge and a proxy key known to the proxy. The proxy response is then sent to the verification authority along with an identifier for the reader. The reader then authenticates an RFID tag by sending a tag response to the verification authority, which determines whether the reader is authentic based on the authenticity of the proxy response.

A sensor node includes: a sensor part configured to sense information from a sensor target; a calculation part configured to digitize at least one data of a portion or all of the sensed sensor information and calculate the digitized data to abstracted data indicating a quantity of state; and an internal communication part configured to transmit the abstracted data to a controller node via a network.

A method and a user device (10) for adapting a signaling of the field device (100) that can be displayed via a signal display (102) of a field device (100) are proposed. For this purpose, an user device (10) is used to define a color tone of at least one display element (104) of the signal display (102) of the field device (100), an attribute is assigned to the defined color tone of the at least one display element (104) of the signal display (102), wherein the attribute represents a meaning of the determined color tone for indicating a state of the field device (100), and a control signal is transmitted from the user device (10) to the field device (100), wherein the control signal contains information regarding the determined color tone and regarding the attribute associated with the determined color tone.
