Abstract: A backpack that includes an airbag and a release module that comprises a control unit and a gas cartridge. The backpack is configured such that the airbag, in a standby state, is deflated and stowed in a storage space of the backpack. The backpack is also configured such that the airbag is automatically inflated, in response to the control unit detecting a fall of a user of the backpack, by releasing gas from the gas cartridge into the airbag. The backpack is further configured such that the airbag, in an inflated state, protects a cervical spine and/or a chest region and/or shoulder region of the user.

Abstract: In an analyte evaluation method for evaluating an analyte, AC voltage is applied between a substrate electrode on a substrate and a counter electrode, and signals obtained from a marker provided on an analyte bound to the substrate electrode are observed, wherein the frequency of the AC voltage is changed and the behavior of the average value of the marker signals is observed. A novel, highly-selective, low-noise method of evaluating a object of evaluation is thus achieved.
