Abstract: A method of forming an orthodontic aligner comprises: generating a teeth digital model; generating a digital dental model based thereon; assigning an identifier to the digital model; forming a dental model, marked with the identifier, corresponding to the digital model; coding a RFID chip within a pallet with the identifier; placing the dental model upon the corresponding pallet, based on the identifier, to form a model/pallet pair; placing the model/pallet pair into a model/pallet vessel; placing a biocompatible thermoplastic sheet upon a membrane stretched about a pressurizable chamber; heating the thermoplastic sheet; placing the membrane and the heated sheet adjacent the model/pallet pair; pressurizing the chamber to apply pressure to the membrane to form the sheet onto the model to form a molded aligner sheet; and cooling the molded aligner sheet to form the orthodontic aligner. The membrane creates a physical barrier between the applied pressure and the sheet.

Abstract: Methods and systems are provided for enhancing security of encrypted messages. One or more bits may be selected in an encrypted message, with the one or more bits being selected such that there is no sequence of consecutive bits in the message, having a length that is greater than or equal to a defined threshold value, that is free of bit errors. An adjustment may be applied to the encrypted message prior to transmitting the message to introduce bit errors in the message, with the adjustment being configured to affect the one or more selected bits. The adjustment may include inverting the one or more selected bits. The one or more bits may be selected and/or adjustment may be configured to reduce detectability of an encryption key used in encrypting messages.

Abstract: Methods and systems are provided for reducing detectability of encryption keys, which may be used to encrypt messages transmitted in a network (e.g., between a base station and a mobile station, such as over the air). Random bit errors may be introduced into the messages to artificially lowering transmission quality, thus makes it harder to detect the encryption key from well-known messages. The random bit errors may be introduced by inverting one or more randomly selected bits in the encrypted message prior to transmitting.

Abstract: In a method for adjusting a gas sensor having a hollow chamber connected to a measuring gas chamber and having an electrochemical pump cell electrochemically pumping the gas component into or out of the hollow chamber, at least two pumping-in phases are provided in which the gas component is pumped into the hollow chamber by the electrochemical pump cell, and at least two pumping-out phases are provided in which the gas component is pumped out of the hollow chamber by the electrochemical pump cell. On the basis of at least one feature of the pump current during the pumping-out phases (Mout), at least one piece of information for adjusting the gas sensor is generated. A parameter regarding the pumping-in is predefined differently in the at least two pumping-in phases.
