Example embodiments relate to radio-frequency identification (RFID) tags for liquid monitoring. An example RFID tag includes an antenna configured to communicate with an RFID reader. The antenna includes a radiating plane. The antenna also includes a ground plane. The RFID tag is attachable to a container. A reactance associated with the antenna is modifiable based on a temperature and a volume of a liquid within the container and adjacent to the ground plane. The RFID tag also includes an integrated circuit that includes a memory. The integrated circuit is configured to modulate the antenna in response to an RFID signal from the RFID reader based on the reactance associated with the antenna.

Systems and methods of monitoring progress of delivery of a patient-specific medication are disclosed. A patient/medication identification (ID) device is provided on a package containing the medication, the patient/medication ID device comprising medication/patient information indicative of the medication and the patient. At least one location ID device is provided at a location, the at least one location ID device comprising a unique location ID associated with the location. The medication/patient information and the patient/medication ID are read. Delivery progress information indicative of a last-known read location where at least one of the medication/patient ID information and the unique location identifier was read is generated. The delivery progress information is stored in a database. The delivery progress information is accessed from the database in response to the request. A delivery status of the medication is indicated to the user.

An interrogation and detection system for detection of surgical implements within a patient's body, the system including One or more RFID tags affixed to a surgical implement within the patient's body. Each RFID tag being configured to transmit a return signal when energized, and a remote signal generator configured to generate an energizing signal for the one or more RFID tags. The signal generator operably coupled to the in-vivo introducible antenna via a communication cable. The system further includes an in-vivo introducible antenna configured to be inserted through a trocar-cannula assembly into a surgical site within the patient's body. Wherein the tubular channel defines a shape having a dimension “D1”, such that the dimension “D1” of the tubular channel is less than the dimension “D2” of the in-vivo introducible antenna.

A method may include receiving, from a scanning device, a first scan of a first identifier of a first slot within a package unit or a first item to be disposed within the package unit. A correct item to be disposed within the first slot having the first identifier or a correct slot for receiving the first item having the first identifier may be determined based on the first identifier and a packing order associated with the package unit. A user interface may be generated to display an indication of the correct item to be disposed within the first slot having the first identifier or the correct slot for receiving the first item having the first identifier. Whether the correct item is disposed within the first slot or the first item is dispose within the correct slot may be determined based on a third scan of a third identifier.

A RFID reader magnetically attachable to a smart phone includes a circuitry adaptor and a RFID access device. The circuitry adaptor is plugged into a USB connector of the smart phone. The RFID access device is magnetically and detachably connected to the circuitry adaptor, so that electricity and signals from the smart phone are transmitted to the RFID access device, and RFID tag signals picked up by the RFID access device are transmitted to the smart phone. When the RFID access device undergoes external impact, the circuitry adaptor and the RFID access device are detached from each other without damaging the USB connectors.

Handheld scanning devices are disclosed herein. An example handheld scanning device includes a main housing, an antenna housing, an antenna mounting bracket, and a first radio frequency identification (RFID) antenna. The main housing includes a main body portion and a grip portion operably coupled with the main body. The main housing defines a main housing cavity. The antenna housing is operably coupled with the main housing and defines an antenna housing cavity. The antenna mounting bracket is at least partially disposed within the antenna housing cavity and is operably coupled with the antenna housing and the main body portion of the main housing. The first RFID antenna is at least partially disposed within the antenna housing cavity and is operably coupled with the antenna mounting bracket.

An RFID device includes a case, an antenna, and a power receiving coil. The case includes a rotation mechanism. The antenna is provided in the case. The power receiving coil is provided in the case away from the antenna in an axial direction of the rotation mechanism. The power receiving coil is connected to a power receiving unit that charges a battery. The power receiving coil has a cylindrical shape.

Systems and methods for aligning a mobile device and a document are disclosed. An exemplary method comprises the steps of determining a model identifier from the mobile device; associating the model identifier with a device configuration from a source; receiving an image of the document taken by the camera of the mobile device; identifying a document type; associating the document type with a document configuration from the source; selecting an alignment feedback schema based on the device configuration and the document configuration; generating alignment feedback based on the image processing; detecting for a data connection between the mobile device and the document; and generating a connection indication when the data connection is detected.

Systems and methods for linking real world activity, such as real world commercial activity or real world data collection activity, with a location-based parallel reality game are provided. In particular, a game server hosting a parallel reality game can modify, update, or add to game data stored in a game database associated with the parallel reality game to include certain game features in the parallel reality game linked with real world activity in the real world. The game features can be linked with activities in the real world such that player actions associated with the game features in the virtual world can lead to or encourage activity in the real world, such as commercial activity and/or data collection activity in the real world. A one-time password may be used to validate a player's location in the real world and to enable controlled access to game features in the virtual world.

A non-transitory computer-readable medium stores instructions causing a processor to generate a menu displaying representations of a plurality of cards, the cards having associated card data; receive, from a user input device, a selection corresponding to a selected one of the cards; update the menu to display a representation of the selection; and authorize transmission of the card data associated with the selected card to complete a transaction.
