Embodiments for device pairing using optical codes are described. One embodiment is a wearable device with an image sensor configured to capture an image including a first optical code from a first host device. The wearable device decodes the first optical code, and in response to the first optical code, initiates broadcast of a pairing advertisement. The host device displays a second optical code in response to the pairing advertisement, and the wearable device captures and processes the second optical code to determine a host pairing advertisement code. The wearable device then, in response to the second optical code, initiate broadcast of a second pairing advertisement including the host pairing advertisement code. In various embodiments, a secure wireless channel is then established and used for further secure communications.

A bioamplifier for analyzing electroencephalogram (EEG) signals is disclosed. The bioamplifier includes an input terminal for receiving an EEG signal from a plurality of sensors coupled to a user. The bioamplifier also includes an analogue-to-digital converter arranged to receive the EEG signal from the input terminal and convert the EEG signal to a digital EEG signal. A data processing apparatus within the bioamplifier is arranged to receive the digital EEG signal from the analogue-to-digital converter and programmed to process, in real time the digital EEG signal using a first machine learning model to generate a cleaned EEG signal having a higher signal-to-noise ratio than the digital EEG signal. The bioamplifier further includes a power source to provide electrical power to the analogue-to-digital converter and the data processing apparatus. The bioamplifier includes a housing that contains the analogue-to-digital converter, the data processing apparatus, the power source, and the sensor input.

An access control system for a premises includes a first scanning device for detecting when an individual having an authorized presence in a unique location in the premises has left the premises, the individual having a handheld device; a second scanning device for determining a location of another individual who is not in the premises, the another individual having another handheld device; nd a server computer in communication with the first scanning device, the second scanning device, the handheld device and the another handheld device, the server computer determining from the first scanning device that the individual has left the premises, and upon said determining, further determining whether the another individual is within a predetermined proximity to the premises, and authorizing access to the unique location in the premises to the another individual if the another individual is within said predetermined proximity.

Secure identifiers for a series of articles are generated by encoding a characterising value such as a time stamp or serial number of each article with a pointer to a database entry such as a blockchain entry storing a range of valid characterising values, or other rule permitting the validation of each characterising value. When an identifier is challenged, the pointer is extracted and used to retrieve the rule, against which the characterising value extracted from the same identifier is tested.

A slip processing device including a scanner which irradiates a slip with a light beam and reads identification information from a barcode provided on the slip, a camera which captures an image of the slip, and a processor which functions as an information acquisition control section which starts reading of the identification information by the scanner and image capturing of the slip by the camera, in response to an information acquisition instruction from a user, and a recording control section which records the captured image of the slip in a predetermined recording section on condition that the reading of the identification information has been judged as successful.

The present invention includes methods and apparatus for the automated provision of goods through the use of scanning systems. More specifically, the present invention provides a method for automatically conveying which goods are being ordered, where the goods will be picked up, an associated method of payment, kitchen fulfillment, item tracking, and automatic delivery by a dispenser apparatus. In preferred embodiments, the present invention is applied to the automated ordering and pick-up of food items at a fast food restaurant and delivery to a food dispenser at a customer location.

In accordance with some embodiments, a physical game element such as a wagering chip or a playing card may be utilized to implement a promotion scheme on an electronic card table (e.g., using RFID or optical imaging technology). During a game it may be determined whether the element is associated with special functionality (e.g., entitles the player to a payout multiplier, special payout table, bonus prize or other benefit). The special functionality may have been previously associated with the element or associated with the element during the game (e.g., dynamically and/or randomly). In accordance with some embodiments a player is not able to readily discern the special functionality by a physical inspection of the physical game element and is only notified of the special functionality once the physical game element is used in a qualifying action (e.g., during a wager at an electronic card table).
