  • Publication number: 20170287297
    Abstract: A security system for deployment within a retail environment is shown. First tags (108 to 112) are concealed within an item of merchandise. Each of these first tags is configured to transmit a first signal modulated to specify a unique first tag code in response to being energised at an exit gate. Second tags (113 to 117) are each independently attached to the merchandise and are configured to communication with mobile devices to facilitate the purchase of the items. A data communication apparatus (119) communicates with mobile devices and controls responses of an exit gate when detecting output signals from the first tags. User selected tags transmit second output signals to a mobile device in response to respective user interactions, with each for the second output signals being modulated by a unique second code. The mobile devices relay received second codes to the communication system.

  • Publication number: 20170124827
    Abstract: An association between a user of a mobile device (301) and an item of merchandise (501) is shown, in which each item of merchandise as a tag (601) attached thereto. The movement of tags is monitored to produce movement data (801). Proximity data is generated for each mobile device identifying tags that are in close proximity (802). The movement data is processed in combination with the proximity data to identify an association between a user and a mobile device and an item of merchandise to which an associated tag has been attached (803).

  • Publication number: 20160027271
    Abstract: A security tag is shown for location upon an article and removal from the article upon receiving authorisation. An internal processor (303) is arranged to transmit an output signal to an external processor indicating that a customer has identified an interest in an article. A physical switch (103) is operated to initiate a procedure for purchasing the article and releasing the tag. The tag transmits an output signal to initiate a release procedure and then receives an input signal to effect a release. The output signal is received by a mobile device and the mobile device interacts with an administration system directly to effect the purchase of the item prior to the administration system issuing the input signal. After receiving the input signal, actual release is only achieved after a further manual operation being performed by the user.

  • Patent number: 6758615
    Abstract: Embodiments of the present invention are directed to a computer keyboard having a key sensing device that provides two levels of sensing by generating electrical signals depending on the force applied on the keys. The different levels of key sensing can be used to provide different functions, for instance, in a software application. This key sensing functionality can be provided on all or only some of the keys of the keyboard. For example, the different pressure levels applied on the key can be used to control cursor movement or scrolling and to produce pressure-based shifting between lower case and upper case. A method of providing pressure sensitive key functionalities for a keyboard comprises producing a signal by applying a pressure to a key which is configured to produce different signals in response to different pressure levels applied to the key. A user interface response is generated based on the signal produced by the pressure applied to the key.
