摘要： The navigation system includes a series of bar codes and a bar code reader. The bar codes are placed at positions throughout the area to be navigated. The bar code readers scan the bar codes as a user moves through the area to be navigated. The navigation system may include a processor which includes instructions for receiving the user's current position and at least one location the user wishes to reach. The processor assembles the most efficient route from the user's position to the locations the user wishes to reach. The navigation system may include an augmented reality viewing device which receives signals from the processor and displays an augmented reality view to the user. The augmented reality view includes augmented reality images which provide step-by-step instructions from the user's position to the locations the user wishes to reach.

摘要： The inventory management system (“the system”) includes a series of bar codes and a bar code reader. The bar codes are placed around the inventory storage area on or near containers which store inventory items. The bar codes identify the contents of the container. The system includes a bar code reader and an augmented reality viewing device. The system includes a processor which stores instructions for identifying the bar codes associated with each of the inventory items in an order. When the bar code reader scans a bar code associated with an item in the order, the augmented reality viewing device emits a cue that indicates the item should be picked. The containers may be connected to sensors which detect when an item has been removed and which transmit the sensor data to a processor. The processor may include instructions for processing the sensor data to maintain a current inventory.

摘要： The method uses a device which measures the volatile organic compounds (VOCs) present in headspaces of fluid samples to differentiate between authentic and synthetic urine samples. The method includes the use of a device which includes an array of resistive microchemical sensors. The device may be exposed to samples of synthetic and authentic urine to identify a pattern of VOCs in each, these steps being referred to herein as training the device. The device may then be exposed to a urine sample of unknown authenticity and a pattern of VOCs identified. The pattern of VOCs from the urine sample of unknown authenticity may be compared to those of synthetic and authentic urine. In some embodiments the device is installed in a toilet. The method may be used to identify a false sample provided for a urine analysis intended to screen for use of illicit drugs.
