The transmission of flight instructions from a ground unit to an aircraft comprising an onboard system. The ground unit is configured to generate, on the basis of flight data intended for the aircraft, at least one optical symbol containing a flight instruction. The onboard system comprises an optical reader and a flight management system. The optical reader is configured to read the optical symbol and to transfer the flight instruction contained in the symbol to the flight management system to prepare the flight of the aircraft.

A system and method for identifying test bars formed during a selective laser sintering build. A part cake is formed during a selective laser sintering build. The part cake comprises parts formed from a powder by selective laser sintering and unsintered powder around the formed parts. The parts include test bars for performing material testing. Each test bar includes a plurality of indentations in a first grip section and a second grip section. The plurality of indentations are arranged in a information providing pattern that is adapted to be readable after the test part is removed from the part cake.

A cube for use in a restaurant allowing patrons to more easily notify their server they are in need of something. The cube is equipped with a lighting mechanism that adjusts colors that represent the status of the patrons dining. The cube contains a shell that has an upper surface and lower surface separated by an indent. The cube has a pair of switches that reside within a divot slightly larger in size that the switch. The charging station for the cube has a dock, a layer, and a power supply. The dock has a base equipped with a plurality of dock base towers, each having a plurality of dock tower connections. The dock base has a plurality of base supports each having a central plug. The layer also has layer connection towers each equipped with layer tower connections allowing the layer to function in tandem with the dock base.

Devices are disclosed that provide a way to store and share memories. The devices include a digital memory code which can be scanned to retrieve the memory from an internet accessible location. The digital memory code can be a binary code which has a visual appearance of, for example, a pattern of long and short rectangles.

System and methods for processing audio signals are disclosed. In one implementation, a system may include a wearable apparatus including an image sensor to capture images from an environment of a user; an audio sensor to capture an audio signal from the environment of the user; and at least one processor. The processor may be programmed to receive the audio signal captured by the audio sensor; identify at least one segment including speech in the audio signal; receive an image including a representation of a code; analyze the code to determine whether the code is associated with the user and/or the wearable apparatus; and after determining that the code is associated with the user and/or the wearable apparatus, transmit at least one segment of the audio signal, at least one image of the plurality of images, and/or other information to a computing platform.

A method of establishing a wireless operating communication between the extracorporeal blood treatment device and a medical accessory and extracorporeal blood treatment device configured for implementing the method are provided; the method comprises the steps of establishing a wireless auxiliary communication between the blood treatment device and the medical accessory, transferring configuration data using the wireless auxiliary communication and establishing the wireless operating communication between the blood treatment device and the medical accessory based on the configuration data. A maximum operating distance of the wireless auxiliary communication is shorter than a maximum operating distance of the wireless operating communication.

A method and system for writing a label (defined within a predetermined region of the sample 110), the label displaying a visible layout of light-modified regions in a predetermined spatial arrangement. The method comprises: modifying regions of a material within the label using light, wherein the modifying comprises using light of a first polarisation state to provide photo-induced optically active regions of a first type having a first optical activity state which is characteristic of having been formed by light of the first polarisation state, in order to encode covert information in the label using the locations of the first type of light-modified regions within the spatial arrangement of the label.

An authentication device comprising a woven authentication pattern, wherein the woven authentication pattern comprises a plurality of pattern forming woven elements each defining at least one pattern defining element or a plurality of pattern defining elements, and each pattern forming woven element is formed by a plurality of threads having contrasting optical or visual properties in twisted mutual engagement, wherein said pattern defining element has a spiralling outline or boundary and adjacent or abutting pattern defining elements of a pattern forming woven element are visually or optically distinguishable.

A connector assembly comprises a first housing, a second housing, a machine readable identifier coupled to the second housing, and a position assurance lock disposed proximate to the second housing. The position assurance lock is configured to secure the first housing to the second housing and place the machine readable identifier in a first state or a second state, depending on whether the first housing is secured to the second housing.

A method includes determining a value amount associated with a transaction card having an optical code. The method also includes, based on a transaction involving the transaction card, updating the value amount. The method also includes determining that the optical code has been read. Responsive to the optical code being read, the method includes causing a display associated with the transaction card to render the value amount.
