  • Publication number: 20190197600
    Abstract: An intellectual shopping system includes a scanning apparatus, a cloud server, and an application program installed in a mobile device. The mobile device is bound to the scanning apparatus through the application program. When shopping physically, the scanning apparatus is used to scan sensing data of a merchandise for uploading to the cloud server. The cloud server inquires corresponding merchandise information based on the sensing data, and then adds the merchandise information to a virtual shopping cart, and transmits the merchandise information to the mobile device for displaying. Once receiving an external operation through the application program, the mobile device performs a checkout action for the virtual shopping cart. Further, the merchandise of the virtual shopping cart is delivered directly from a warehouse to a designated address by a logistic system after the checkout action, no need for a consumer to convey the merchandise by himself/herself.

  • Patent number: 10312570
    Abstract: A long-distance radio frequency anti-metal identification tag is provided. When a bottom surface of an insulating spacer plate is attached to the surface of a metal object and an electronic tag reading device is used to read a radio frequency identification chip on a second antenna. A resonant cavity is formed between a slot of a first antenna and the surface of the metal object through the isolation of the insulating spacer plate, such that the second antenna located at the position of the resonant cavity resonates with an electromagnetic wave signal reflected on the surface of the metal object by the first antenna. The electromagnetic wave signal is transmitted to the radio frequency identification chip, or the feedback signal of the radio frequency identification chip is transmitted out. The overall UHF electronic tag is resistant to a metal interference and has the performance of long-distance reading.

  • Publication number: 20190015611
    Abstract: A method is described for supplying a metered amount of a liquid medicament to an aerosolizing device. The method utilizes a dispenser comprising an elongate dispenser body having a proximal end and a tip at a distal end through which a liquid medicament is dispensed. The dispenser further comprises a dispensing mechanism that operates to dispense a metered quantity of the liquid medicament from the tip each time the dispenser body is compressed. The dispenser is grasped with one hand such that the fingers wrap around the dispenser body, with the thumb closest to the proximal end and the last finger closest to the tip. The tip is inserted into an opening of an inhaler and the elongate body is forced toward the tip to cause the dispenser body to compress, thereby operating the dispensing mechanism and causing a metered quantity of the liquid medicament to eject into the inhaler.
